    ___ N.W.2d ___
    Filed December 29, 2015.   Nos. A-15-197, A-15-234, A-15-235.
    1.	 Workers’ Compensation: Appeal and Error. On appellate review, the
    findings of fact made by the trial judge of the Workers’ Compensation
    Court have the effect of a jury verdict and will not be disturbed unless
    clearly wrong.
    2.	 Workers’ Compensation: Evidence: Appeal and Error. If the record
    contains evidence to substantiate the factual conclusions reached by the
    trial judge in workers’ compensation cases, an appellate court is pre-
    cluded from substituting its view of the facts for that of the compensa-
    tion court.
    3.	 Workers’ Compensation. Under Neb. Rev. Stat. § 48-120(1)(a) (Supp.
    2015), an employer is liable for all reasonable medical, surgical, and
    hospital services which are required by the nature of the injury and
    which will relieve pain or promote and hasten the employee’s restoration
    to health and employment.
    4.	 ____. Whether medical treatment is reasonable or necessary to treat
    a workers’ compensation claimant’s compensable injury is a question
    of fact.
    5.	 Workers’ Compensation: Appeal and Error. Upon appellate review,
    the findings of fact made by the trial judge of the compensation court
    have the effect of a jury verdict and will not be disturbed unless
    clearly wrong.
    6.	 Workers’ Compensation. A procedure that provides relief from
    the symptoms of an injury is compensable under Neb. Rev. Stat.
    § 48-120(1)(a) (Supp. 2015), regardless of whether those symptoms
    produce a permanent physical impairment or disability.
    7.	 ____. Neb. Rev. Stat. § 48-120(1)(a) (Supp. 2015) requires three factors
    be established before payment for a medical service is required: that the
    service (1) is reasonable, (2) is required by the work injury, and (3) will

    relieve pain or promote or hasten the employee’s restoration to health
    and employment.
    8.	 Workers’ Compensation: Expert Witnesses: Physicians and
    Surgeons. The Workers’ Compensation Court is the sole judge of the
    credibility and weight to be given medical opinions, even when the
    health care providers do not give live testimony.
    9.	 ____: ____: ____. Resolving conflicts within a health care provider’s
    opinion rests with the Workers’ Compensation Court, as the trier
    of fact.
    10.	 Workers’ Compensation: Expert Witnesses: Physicians and
    Surgeons: Appeal and Error. When the record presents nothing more
    than conflicting medical testimony, an appellate court will not substitute
    its judgment for that of the Workers’ Compensation Court.
    11.	 Workers’ Compensation: Proof. An applicant seeking modification of
    a workers’ compensation award, or an approved agreement and stipula-
    tion, under Neb. Rev. Stat. § 48-141 (Reissue 2010) must prove by a
    preponderance of the evidence that an increase in his or her incapacity
    is due solely to the injury resulting from the original accident.
    12.	 ____: ____. To establish a change in incapacity under Neb. Rev. Stat.
    § 48-141 (Reissue 2010), an applicant must show a change in impair-
    ment and a change in disability.
    13.	 Workers’ Compensation: Words and Phrases. In a workers’ compen-
    sation context, impairment refers to a medical assessment whereas dis-
    ability relates to employability.
    14.	 Workers’ Compensation: Appeal and Error. Whether an injured
    worker’s incapacity has increased since the entry of an award of ben-
    efits so as to justify modification of the award is a finding of fact, and
    upon appellate review, the findings of fact made by the trial judge have
    the effect of a jury verdict and will not be disturbed on appeal unless
    clearly wrong.
    15.	 Workers’ Compensation: Words and Phrases. Under Neb. Rev. Stat.
    § 48-121 (Reissue 2010), a workers’ compensation claimant may receive
    permanent or temporary workers’ compensation benefits for either par-
    tial or total disability. “Temporary” and “permanent” refer to the dura-
    tion of disability, while “total” and “partial” refer to the degree or extent
    of the diminished employability or loss of earning capacity.
    16.	 ____: ____. Temporary disability ordinarily continues until the claim-
    ant is restored so far as the permanent character of his or her injuries
    will permit.
    17.	 Workers’ Compensation. Compensation for temporary disability
    ceases as soon as the extent of the claimant’s permanent disability
    is ascertained.

    18.	 ____. Temporary disability should be paid only to the time when it
    becomes apparent that the employee will get no better or no worse
    because of the injury.
    19.	 Workers’ Compensation: Words and Phrases. The term “maximum
    medical improvement,” describes the point of transition from temporary
    to permanent disability.
    20.	 Workers’ Compensation. Once a worker has reached maximum medi-
    cal improvement from a disabling injury and the worker’s permanent
    disability and concomitant decreased earning capacity have been deter-
    mined, an award of permanent disability is appropriate.
    21.	 ____. Generally, whether a workers’ compensation claimant has reached
    maximum medical improvement is a question of fact.
    22.	 Workers’ Compensation: Judgments: Time: Appeal and Error. The
    Nebraska Workers’ Compensation Court may, on its own motion or on
    the motion of any party, modify or change its findings, order, award, or
    judgment at any time before appeal and within 14 days after the date of
    such findings, order, award, or judgment.
    23.	 Workers’ Compensation. The Nebraska Workers’ Compensation Court
    may rule upon any motion addressed to the court by any party to a suit
    or proceeding, including, but not limited to, motions for summary judg-
    ment or other motions for judgment on the pleadings but not including
    motions for new trial.
    24.	 Pleadings: Judgments. A postjudgment motion must be reviewed
    based on the relief sought by the motion, not based on the title of
    the motion.
    25.	 New Trial: Words and Phrases. A new trial is defined as a reexamina-
    tion in the same court of an issue of fact after a verdict by a jury, report
    of a referee, or a trial and decision by the court.
    26.	 Evidence: Words and Phrases. Newly discovered evidence has been
    defined as evidence which neither the litigant nor counsel could have
    discovered by the exercise of reasonable diligence.
    27.	 New Trial: Evidence. Newly discovered evidence must be more than
    merely cumulative; it must be competent, relevant, and material, and of
    such character as to reasonably justify a belief that its admission would
    bring about a different result if a new trial were granted.
    28.	 Appeal and Error. An appellate court is not obligated to engage in an
    analysis that is not necessary to adjudicate the case and controversy
    before it.

    INTRODUCTION
    Debra Yost appeals, and Davita, Inc., cross-appeals, from the
    further award of the Workers’ Compensation Court. On appeal,
    Yost argues that the compensation court erred in finding that
    Davita was not required to pay for the cost of her spinal
    cord stimulator.
    On cross-appeal, Davita challenges the compensation court’s
    finding that Yost suffered an increase in incapacity and is
    now at maximum medical improvement (MMI) for her men-
    tal injury. It also challenges the court’s refusal to reopen the
    record for further evidence. We find no merit to the arguments
    made on appeal or cross-appeal and therefore affirm.
    BACKGROUND
    On June 3, 2008, Yost suffered a work-related injury to her
    lower back. In an award dated November 25, 2009, the com-
    pensation court found that she reached MMI with respect to
    her low-back injury and sustained a 35-percent permanent loss
    of earning capacity. Davita was ordered to pay Yost’s past and
    future medical expenses.
    On May 26, 2010, Yost filed an application for modifi-
    cation, alleging that she suffered material and substantial
    changes in her physical condition and an increase in incapac-
    ity due to her work-related injuries. Yost and Davita entered
    into an agreement regarding modification of the award. The
    parties agreed that Yost suffered an increase in incapacity due
    solely to her work injury and again became temporarily totally
    disabled pending low-back surgery, which was approved by
    - 486 -
    Decisions of the Nebraska Court of A ppeals

    YOST v. DAVITA, INC.

    23 Neb. Ct. App. 482
    Davita. The parties further stipulated that the worsening of
    Yost’s back condition also caused or aggravated depression
    symptoms. Thus, she was entitled to all reasonable and neces-
    sary future medical care for her low-back injuries as well as
    her depression symptoms. The compensation court approved
    the parties’ agreement and stipulations.
    In January 2011, Yost underwent spinal fusion surgery at
    the L4-5 and L5-S1 levels of her spine. Following surgery,
    she began to experience back spasms and her pain continued.
    She underwent additional treatment, including pain manage-
    ment, therapy, and medication. Eventually, based on Yost’s
    continued pain and problems stemming from her lower back,
    her spinal surgeon recommended a spinal cord stimulator,
    which he believed would provide her some relief. He referred
    her to an anesthesiologist and pain specialist who determined
    that Yost was a candidate for a trial spinal cord stimulator,
    which she received in March 2013. The trial was consid-
    ered successful, and Yost received a permanent stimulator in
    April 2013.
    At the time Yost was undergoing continued treatment for
    her back, she was also seeking treatment for depression,
    insomnia, and anxiety. In May 2011, Yost was diagnosed
    with major depression and prescribed antidepressant medica-
    tion. In August, her treating psychiatrist opined that Yost’s
    depression was secondary in large part to her June 2008
    work injury. He did not believe that she was able to work at
    all given that her depression was impairing her concentra-
    tion. In May 2013, her treating psychiatrist reported that her
    condition remained unchanged and that in his opinion, Yost
    remained permanently and totally disabled from a psychiat-
    ric standpoint.
    Davita filed a petition for modification, alleging that Yost
    experienced a decrease in incapacity and had reached MMI.
    Yost filed an answer and counterclaim for modification,
    claiming that she had again reached MMI and requesting
    that the court find her permanently and totally disabled as

    a result of her work-related injuries. She also requested that
    the court order Davita to cover the cost of her spinal cord
    stimulator.
    Trial was held on the parties’ requests for modification, and
    the compensation court entered a further award on February
    13, 2015. The court found that Yost had reached MMI for
    her low-back condition as of October 19, 2012, and for her
    psychological condition as of June 18, 2014. Relying on the
    opinions of Drs. Robert Arias and Vithyalakshmi Selvaraj, the
    court determined that Yost is completely disabled as a result of
    her depression.
    The court also found that Davita was not responsible for
    the cost of the spinal cord stimulator. The court acknowledged
    Yost’s testimony that the stimulator alleviated some symptoms
    in her legs and feet, but it emphasized that she still has pain
    in her lower back. The court also noted that several physicians
    opined that the stimulator was not necessary and would not
    alleviate her symptoms. Further, the court observed that Yost
    testified that the stimulator helped her functionality but did
    not aid in her return to work.
    On February 24, 2015, Davita filed a motion to reopen the
    evidence. Davita alleged that it had newly discovered evidence
    relevant to the issues in the case. At a hearing on the motion,
    an affidavit from Yost’s former husband was received into
    evidence wherein he stated that he had personal knowledge
    regarding misrepresentations Yost made as to the cause and
    extent of her back injuries and manipulations she made of
    medical treatment for the purpose of increasing the value of
    her workers’ compensation claim. The compensation court
    subsequently entered an order finding that it lacked authority
    to open the record to receive additional evidence after having
    already rendered its decision.
    On March 3, 2015, Davita filed a motion for offer of proof
    requesting the opportunity to make an offer of proof to allow
    it to timely perfect an appeal from the denial of its request
    to reopen the evidence. On March 4, Yost filed a notice of

    YOST v. DAVITA, INC.
    Cite as 
    23 Neb. Ct. App. 482
    her intent to appeal the further award. A hearing on Davita’s
    motion for offer of proof was held on March 6, and the com-
    pensation court determined that it no longer had jurisdiction
    over the matter because Yost had already filed her notice of
    appeal. Therefore, Davita’s motion was dismissed. Yost timely
    appeals the further award, and Davita cross-appeals the denial
    of its postjudgment motions. The matters have been consoli-
    dated for our consideration.
    ASSIGNMENTS OF ERROR
    On appeal, Yost assigns that the compensation court erred
    in failing to require that Davita pay for the spinal cord
    stimulator.
    On cross-appeal, Davita assigns that the compensation
    court erred in finding that (1) Yost suffered an increase in
    incapacity due solely to her work-related accident and that
    she is at MMI for her mental injury, (2) it lacked authority to
    reopen the evidentiary record, and (3) it lacked jurisdiction
    over Davita’s motion to make an offer of proof.
    STANDARD OF REVIEW
    [1,2] Under Neb. Rev. Stat. § 48-185 (Cum. Supp. 2014),
    an appellate court may modify, reverse, or set aside a Workers’
    Compensation Court decision only when (1) the compensa-
    tion court acted without or in excess of its powers; (2) the
    judgment, order, or award was procured by fraud; (3) there is
    not sufficient competent evidence in the record to warrant the
    making of the order, judgment, or award; or (4) the findings
    of fact by the compensation court do not support the order
    or award. Manchester v. Drivers Mgmt., 
    278 Neb. 776
    , 
    775 N.W.2d 179
    (2009). On appellate review, the findings of fact
    made by the trial judge of the Workers’ Compensation Court
    have the effect of a jury verdict and will not be disturbed
    unless clearly wrong. 
    Id. If the
    record contains evidence
    to substantiate the factual conclusions reached by the trial
    judge in workers’ compensation cases, an appellate court is

    precluded from substituting its view of the facts for that of the
    compensation court. 
    Id. ANALYSIS Spinal
    Cord Stimulator.
    Yost asserts that the compensation court erred in finding
    that the cost of the spinal cord stimulator was not reasonable.
    We find no merit to this argument.
    [3-5] Under Neb. Rev. Stat. § 48-120(1)(a) (Supp. 2015),
    an employer is liable for all reasonable medical, surgical,
    and hospital services which are required by the nature of the
    injury and which will relieve pain or promote and hasten the
    employee’s restoration to health and employment. Whether
    medical treatment is reasonable or necessary to treat a work-
    ers’ compensation claimant’s compensable injury is a question
    of fact. Rodriguez v. Hirschbach Motor Lines, 
    270 Neb. 757
    ,
    
    707 N.W.2d 232
    (2005). Upon appellate review, the findings
    of fact made by the trial judge of the compensation court have
    the effect of a jury verdict and will not be disturbed unless
    clearly wrong. 
    Id. In the
    present case, in finding that Davita was not liable
    for the cost of the spinal cord stimulator, the compensation
    court relied upon the opinions of Drs. Timothy Burd, Charles
    Taylon, and Chris Cornett. In an office note dated June 18,
    2011, Dr. Burd reported that after reviewing Yost’s recent MRI,
    he did not identify any significant pathology or reasons for her
    spinal cord stimulator.
    Similarly, in a report dated October 20, 2012, Dr. Taylon
    stated that he was unable to find any objective findings for
    Yost’s continued pain. He stated that he “would challenge
    any predication by any doctor that further procedures on
    [Yost] could possibly make her better” and advised that
    further invasive procedures not be performed. In a report
    a month later, he specifically stated that he did not feel
    that Yost would benefit from a spinal cord stimulator. He
    reported that in his experience, such treatment is a “notorious

    failure” in people with benign pain, especially those involved
    in litigation.
    Dr. Cornett’s report dated August 1, 2014, indicated that he
    agreed with Dr. Taylon. Dr. Cornett noted Yost’s reports that
    the stimulator helped with some of her leg pain and toe numb-
    ness and tingling but did not really help her back pain, and she
    still rated her pain as a 6 or 7 out of 10 primarily in her lower
    back. Dr. Cornett agreed with Dr. Taylon’s opinion that Yost
    was at MMI in October 2012 and therefore did not require
    additional treatment. Thus, he would not have recommended
    the spinal cord stimulator.
    In its further award, the compensation court cited the opin-
    ions from Drs. Burd, Taylon, and Cornett in reaching its deci-
    sion that the spinal cord stimulator was not reasonable treat-
    ment. Specifically, the court stated: “The [c]ourt simply does
    not believe that for the cost incurred the spinal cord stimulator
    was reasonable treatment in light of the limited benefit it pro-
    vided.” Yost interprets the court’s statements as a finding that
    the cost for the spinal cord stimulator was not reasonable. Yost
    misinterprets the court’s finding.
    As stated above, under § 48-120(1)(a), an employer is liable
    for all reasonable medical, surgical, and hospital services which
    are required by the nature of the injury and which will relieve
    pain or promote and hasten the employee’s restoration to health
    and employment. The compensation court found that in light
    of Drs. Burd’s, Taylon’s, and Cornett’s opinions, coupled with
    Yost’s testimony that she still has pain in her lower back after
    the stimulator was implanted, the cost outweighed the benefit,
    resulting in a finding that it was not reasonable treatment. We
    find no error in this analysis.
    [6,7] Yost cites to Pearson v. Archer-Daniels-Midland
    Milling Co., 
    282 Neb. 400
    , 
    803 N.W.2d 489
    (2011), to argue
    that the implementation of the stimulator was reasonable, and
    therefore compensable, because it alleviated some symptoms
    in her legs and feet. In Pearson, the Supreme Court observed
    that a procedure that provides relief from the symptoms of an

    injury is compensable under § 48-120(1)(a) (Reissue 2010),
    regardless of whether those symptoms produce a permanent
    physical impairment or disability. (Emphasis in original.) It
    is important to note, however, that in Pearson, the Supreme
    Court remanded the cause for a factual determination as
    to whether the procedure for which the employee sought
    compensation “falls under the provisions of § 
    48-120.” 282 Neb. at 408
    , 803 N.W.2d at 495. On remand, the Workers’
    Compensation Court found Pearson’s procedure was not com-
    pensable because it was not required by the work-related
    injury and the Supreme Court affirmed. Pearson v. Archer-
    Daniels-Midland Milling Co., 
    285 Neb. 568
    , 
    828 N.W.2d 154
    (2013). In so doing, the court iterated that § 48-120(1)(a)
    requires three factors be established: that the service (1) is
    reasonable, (2) is required by the work injury, and (3) will
    relieve pain or promote or hasten the employee’s restoration
    to health and employment.
    In the present case, Yost focuses only on the factor dealing
    with relief of pain; she ignores the requirements that the serv­
    ice be reasonable and be required by the nature of the injury.
    Although the stimulator afforded relief to some of Yost’s
    symptoms, she admitted that it did not go high enough to
    help her lower back, and when questioned by Dr. Cornett, she
    still rated the pain in her back as a “6 to 7 out of 10.” Thus,
    although there was improvement in some secondary symptoms,
    the stimulator was not providing relief from the main symptom
    of her work-related injury, namely her low-back pain. Given
    the medical testimony of Drs. Burd, Taylon, and Cornett, and
    Yost’s own testimony of the limited relief the stimulator pro-
    vided, we cannot say the court was clearly wrong in determin-
    ing that the spinal cord stimulator was not a reasonable service
    for which Davita was liable.
    [8-10] We recognize that some of Yost’s medical provid-
    ers issued opposing viewpoints and opined that the spinal
    cord stimulator was causally related, reasonable, and neces-
    sary to treat her work-related injuries. However, the Workers’

    Compensation Court is the sole judge of the credibility and
    weight to be given medical opinions, even when the health care
    providers do not give live testimony. Damme v. Pike Enters.,
    
    289 Neb. 620
    , 
    856 N.W.2d 422
    (2014). Resolving conflicts
    within a health care provider’s opinion also rests with the
    compensation court, as the trier of fact. 
    Id. When the
    record
    presents nothing more than conflicting medical testimony, an
    appellate court will not substitute its judgment for that of the
    compensation court. 
    Id. The compensation
    court chose to find
    the opinions of Drs. Burd, Taylon, and Cornett credible, and
    we do not reweigh that decision on appeal. Based on the record
    before us, we cannot say the compensation court was clearly
    wrong in determining that Davita was not liable for the costs
    of the stimulator.
    Increase in Incapacity.
    On cross-appeal, Davita claims that the compensation court
    erred in finding that Yost suffered an increase in incapacity
    due solely to her work-related accident. Davita argues that any
    increase in Yost’s incapacity was not due solely to her work-
    related injury because the compensation court found that any
    pain and treatment related to the L2-3 level of Yost’s spine
    was not related to the June 2008 work accident, and Yost’s
    depression was exacerbated by her generalized back pain,
    which included pain at the L2-3 level. We find no merit to
    this argument.
    [11-14] An applicant seeking modification of a workers’
    compensation award, or an approved agreement and stipula-
    tion, under Neb. Rev. Stat. § 48-141 (Reissue 2010) must

    assessment whereas disability relates to employability. 
    Id. Whether an
    injured worker’s incapacity has increased since the
    entry of an award of benefits so as to justify modification of
    the award is a finding of fact, and upon appellate review, the
    findings of fact made by the trial judge have the effect of a
    jury verdict and will not be disturbed on appeal unless clearly
    wrong. See Rader v. Speer Auto, 
    287 Neb. 116

    (2013).
    In Sands v. School Dist. Of City of Lincoln, 
    7 Neb. Ct. App. 28
    , 
    581 N.W.2d 894
    (1998), this court analyzed the meaning
    and effect of the phrase “due solely to the injury” to determine
    whether the evidence supported a finding that an employee’s
    increased disability was due solely to a prior work injury.
    There, the employee suffered a work-related injury to her
    knee in 1983. She also had degenerative osteoarthritis which
    affected her knee. The employee later sought additional ben-
    efits based on increased disability.
    At the modification hearing, the employee’s physician testi-
    fied that he found it difficult to separate how much disability
    was due to repeated traumatic events and the presence of
    arthritis but that the original work injury was a material and
    substantial factor as it related to the need for knee replace-
    ment and the impairment. He also testified that he was unable
    to determine the amount of impairment that was caused by
    the natural progression of the preexisting conditions or by
    new traumas other than the work accident. He further testi-
    fied that there were several major contributing factors to
    the employee’s treatment including the original work-related
    injury, the degenerative osteoarthritis, the multiple other inci-
    dents of trauma to her knees, and the natural aging process.
    Despite this testimony, the workers’ compensation court found
    that the employee had suffered an increase in disability due
    solely to the original work accident and awarded compensa-
    tion accordingly.
    On appeal, we noted that in Hohnstein v. W.C. Frank, 
    237 Neb. 974
    , 
    468 N.W.2d 597
    (1991), the Supreme Court stated

    that the question to be considered was whether the worker’s
    medical expert evidence sufficiently demonstrated the causal
    connection between the original work-related accident and
    the increased incapacity. We observed that in Hohnstein, the
    Supreme Court ultimately concluded that for medical testi-
    mony to be the basis for an award, it must be sufficiently defi-
    nite and certain that a conclusion can be drawn that there was
    a causal connection between the accident and the disability.
    We reiterated that the compensation court is the sole judge of
    credibility and that an appellate court does not substitute its
    judgment for that of the lower court. We thus affirmed, hold-
    ing that the record did not justify a finding that the trial court
    clearly erred in determining that the increase in incapacity was
    due solely to the original accident.
    In the present case, in reaching its decision that Yost was
    permanently and totally disabled as a result of her psycho-
    logical injury, the compensation court relied on the opinions of
    Drs. Arias and Selvaraj as well as a functional capacity evalu-
    ation. In a November 17, 2014, letter, Dr. Selvaraj wrote that
    although Yost experienced minor stress from family issues, it
    is her depression and psychological conditions associated with
    her work disability that is solely attributable to her incapacity
    and limitations on her ability to work. She further reported that
    all of the psychological and psychiatric treatment Yost received
    was reasonable and necessary to treat injuries resulting from
    the June 2008 work accident.
    Similarly, Dr. Arias agreed that Yost’s psychological con-
    ditions were causally related to injuries from her original
    work accident and complications from her back fusion surgery.
    The functional capacity evaluation accepted the opinions of
    Drs. Arias and Selvaraj and determined that Yost suffered a
    100-percent loss of earning capacity. We cannot find that it was
    clear error when the compensation court relied on these medi-
    cal opinions to find Yost’s increased incapacity was due solely
    to her work injury.

    We also note that the compensation court made a factual
    finding that the L2-3 level was not a pain generator based on
    an opinion by Dr. Cornett. This finding was not challenged on
    appeal. Thus, all of the pain Yost experiences in her back is,
    in fact, related to the work accident. And it is her back pain
    and limitations from her work-related back injury that have
    exacerbated her depression symptoms to the point that she is
    unable to work.
    Based on the record before us, we find no clear error in the
    compensation court’s decision. We therefore affirm the finding
    that Yost sustained a 100-percent loss of earning capacity based
    solely on the 2008 work-related injuries.
    MMI for Psychological Injury.
    Davita next contends that the compensation court errone-
    ously determined that Yost was at MMI for her depression.
    We disagree.
    [15-18] Under Neb. Rev. Stat. § 48-121 (Reissue 2010), a
    workers’ compensation claimant may receive permanent or
    temporary workers’ compensation benefits for either partial
    or total disability. “Temporary” and “permanent” refer to the
    duration of disability, while “total” and “partial” refer to the
    degree or extent of the diminished employability or loss of
    earning capacity. Rodriguez v. Hirschbach Motor Lines, 
    270 Neb. 757
    , 
    707 N.W.2d 232
    (2005). Temporary disability ordi-
    narily continues until the claimant is restored so far as the
    permanent character of his or her injuries will permit. 
    Id. Compensation for
    temporary disability ceases as soon as the
    extent of the claimant’s permanent disability is ascertained. 
    Id. In other
    words, temporary disability should be paid only to the
    time when it becomes apparent that the employee will get no
    better or no worse because of the injury. 
    Id. [19-21] The
    term “maximum medical improvement,” or
    MMI, has been used to describe the point of transition from
    temporary to permanent disability. See 
    id. Once a
    worker
    has reached MMI from a disabling injury and the worker’s

    YOST v. DAVITA, INC.
    Cite as 
    23 Neb. Ct. App. 482
    permanent disability and concomitant decreased earning capac-
    ity have been determined, an award of permanent disability is
    appropriate. 
    Id. Generally, whether
    a workers’ compensation
    claimant has reached MMI is a question of fact. 
    Id. Dr. Arias
    placed Yost at MMI for her depression as of June
    18, 2014, which is the date the compensation court utilized for
    its findings. Dr. Selvaraj, Yost’s treating psychiatrist, indicated
    that she hoped Yost could return to work and continued to treat
    her with the hope of improvement. Nevertheless, Dr. Selvaraj
    also placed Yost at MMI, albeit as of November 17, 2014.
    Dr. Selvaraj explained that if Yost’s physical back injuries are
    not going to get any better, the prognosis for improvement
    for her mental condition is “pretty limited.” It is undisputed
    that Yost is at MMI for her back injury, and she has declined
    additional treatment. Because Yost’s depression is dependent
    upon her physical pain and limitations, the compensation court
    found that Yost is as good as she is going to get physically
    and, therefore, psychologically. Again, we recognize there
    were opinions to the contrary, including medical opinions that
    Yost was “malingering” and that her depression and anxiety
    were motivated by secondary gain. However, the compensa-
    tion court recognized the conflicting evidence as well and
    nevertheless concluded that the preponderance of the evidence
    established that Yost had reached MMI for her psychologi-
    cal injury.
    We repeat that the compensation court is the sole judge of
    the credibility and weight to be given medical opinions, even
    when the health care providers do not give live testimony. See
    Damme v. Pike Enters., 
    289 Neb. 620
    , 
    856 N.W.2d 422
    (2014).
    Resolving conflicts within a health care provider’s opinion also
    rests with the court, as the trier of fact. 
    Id. When the
    record
    presents nothing more than conflicting medical testimony, an
    appellate court will not substitute its judgment for that of the
    compensation court. 
    Id. As such,
    we find no clear error in the
    compensation court’s factual finding that Yost reached MMI
    for her depression.

    Motion to Reopen Evidence.
    In filing a motion to reopen evidence, Davita requested
    that the court reopen the record, accept new evidence, and
    reconsider its decision contained in the further award. Davita
    now claims that the compensation court erred in denying
    its motion to reopen the evidence. We find no merit to this
    argument.
    [22] The Nebraska Workers’ Compensation Court may, on its
    own motion or on the motion of any party, modify or change
    its findings, order, award, or judgment at any time before
    appeal and within 14 days after the date of such findings,
    order, award, or judgment. Neb. Rev. Stat. § 48-180 (Cum.
    Supp. 2014). Thus, because Davita’s motion was filed 11 days
    after entry of the further award and prior to Yost’s appeal, the
    compensation court had the authority under § 48-180 to modify
    its findings.
    [23] However, the compensation court’s authority does not
    include the ability to rule on motions for new trial. The com-
    pensation court may rule upon any motion addressed to the
    court by any party to a suit or proceeding, including, but not
    limited to, motions for summary judgment or other motions for
    judgment on the pleadings but not including motions for new
    trial. Neb. Rev. Stat. § 48-162.03 (Cum. Supp. 2014). We must
    therefore determine whether the compensation court properly
    treated Davita’s motion as a request for a new trial.
    [24] We recognize that Davita’s motion was entitled “Motion
    to Reopen the Evidence or in the Alternative Motion to Modify
    Further Award Pursuant to §[§ ]48-180, 48-162.03 and 48-141.”
    At the hearing, Davita argued that in reality its requests were
    not alternative, but, rather, it was seeking to reopen the evi-
    dence and modify the further award. A postjudgment motion
    must be reviewed based on the relief sought by the motion, not
    based on the title of the motion. Woodhouse Ford v. Laflan,
    
    268 Neb. 722
    , 
    687 N.W.2d 672
    (2004).

    cedure, a new trial is defined as a reexamination in the same

    court of an issue of fact after a verdict by a jury, report of a
    referee, or a trial and decision by the court. See, Neb. Rev.
    Stat. § 25-1142 (Reissue 2008); Woodhouse Ford v. 
    Laflan, supra
    . One of the bases upon which a new trial may be granted
    is newly discovered evidence. See § 25-1142(7). Newly dis-
    covered evidence has been defined as evidence which neither
    the litigant nor counsel could have discovered by the exercise
    of reasonable diligence. State v. Timmens, 
    282 Neb. 787
    , 
    805 N.W.2d 704
    (2011). Newly discovered evidence must also be
    more than merely cumulative; it must be competent, relevant,
    and material, and of such character as to reasonably justify a
    belief that its admission would bring about a different result if
    a new trial were granted. 
    Id. In the
    case at hand, Davita asked the compensation court
    to reopen the record, accept newly discovered evidence, and
    reconsider its prior decision based upon its belief that the new
    evidence would bring about a different result. In other words,
    Davita asserted that if the compensation court weighed the
    newly discovered evidence, it might change its decision find-
    ing that Yost was totally and permanently disabled. Regardless
    of how Davita’s motion was titled, it was seeking a new trial
    based upon newly discovered evidence, which is not permitted
    in the compensation court.
    We recognize that in Woodhouse Ford v. 
    Laflan, supra
    , the
    trial court treated a motion for new trial as a motion to alter
    or amend, a motion which could be heard in the compensa-
    tion court. However, in that case, the moving party asked the
    court to consider newly discovered evidence and then alter its
    judgment after entry of summary judgment, in which the court
    only determined that there were no genuine issues of fact for it
    to decide. Under the definition of a new trial, a party is seek-
    ing a reexamination of an issue of fact after a verdict, report,
    or trial. Thus, in Woodhouse Ford, the moving party was not
    actually seeking a reexamination of an issue of fact because
    no factual findings were made in the entry of summary judg-
    ment. Here, the compensation court made factual findings

    23 Neb. Ct. App. 482
    with respect to the nature and extent of Yost’s disability and
    weighed the credibility of conflicting expert opinions. Thus,
    Davita was, in fact, seeking a reexamination of factual issues,
    and the court properly treated the motion as a motion for new
    trial. We therefore find that the court did not err in denying the
    motion to reopen evidence.
    Motion for Offer of Proof.
    [28] Davita also asserts that the compensation court erro-
    neously denied its motion to make an offer of proof. Davita
    sought to make an offer of proof of the newly discovered evi-
    dence it obtained in order to complete the record for appellate
    purposes. Based upon our finding above that the compensa-
    tion court properly found it did not have the authority to rule
    on the motion to reopen evidence, we need not address this
    assignment of error. An appellate court is not obligated to
    engage in an analysis that is not necessary to adjudicate the
    case and controversy before it. Tierney v. Four H Land Co.,
    
    288 Neb. 586
    , 
    852 N.W.2d 292
    (2014).
    CONCLUSION
    We find no merit to the arguments on appeal or cross-appeal
    and therefore affirm.
