DECISION AND ORDER
This case is decided pursuant to Chapter 410 of the Texas Workers’ Compensation Act and Rules of the Division of Workers’ Compensation adopted thereunder.
ISSUES
A contested case hearing was held on April 30, 2012, to decide the following disputed issue:
- Is the preponderance of the evidence contrary to the decision of the IRO that the claimant is not entitled to 12 additional visits of physical therapy to the left humerus, neck, and low back over 4 weeks for the compensable injury of (Date of Injury)?
PARTIES PRESENT
Petitioner/Claimant appeared and was assisted by PG, ombudsman.
Respondent/Carrier appeared and was represented by RJ, attorney.
BACKGROUND INFORMATION
The Claimant sustained a compensable injury on (Date of Injury), when the forklift he was moving flipped over. The Claimant sustained a broken left humerus, lower back injury, a ruptured spleen, and a neck injury. He had 12 sessions of physical therapy that focused on his back and neck. The Claimant testified that his treating doctor, Dr. M, wants him to undergo more physical therapy for the compensable injury in order to further improve range of motion of his back and neck, and also to address his arm, which was previously not addressed in physical therapy.
Texas Labor Code Section 408.021 provides that an employee who sustains a compensable injury is entitled to all health care reasonably required by the nature of the injury as and when needed. Health care reasonably required is further defined in Texas Labor Code Section 401.011 (22a) as health care that is clinically appropriate and considered effective for the injured employee’s injury and provided in accordance with best practices consistent with evidence based medicine or, if evidence based medicine is not available, then generally accepted standards of medical practice recognized in the medical community. Health care under the Texas Workers’ Compensation system must be consistent with evidence based medicine if that evidence is available. Evidence based medicine is further defined in Texas Labor Code Section 401.011 (18a) to be the use of the current best quality scientific and medical evidence formulated from credible scientific studies, including peer-reviewed medical literature and other current scientifically based texts and treatment and practice guidelines in making decisions about the care of individual patients. The Commissioner of the Division of Workers’ Compensation is required to adopt treatment guidelines that are evidence-based, scientifically valid, outcome-focused, and designed to reduce excessive or inappropriate medical care while safeguarding necessary medical care. Texas Labor Code Section 413.011(e). Medical services consistent with the medical policies and fee guidelines adopted by the commissioner are presumed reasonable in accordance with Texas Labor Code Section 413.017(1).
In accordance with the above statutory guidance, the Division of Workers’ Compensation has adopted treatment guidelines by Division Rule 137.100. This rule directs health care providers to provide treatment in accordance with the current edition of the Official Disability Guidelines (ODG), and such treatment is presumed to be health care reasonably required as defined in the Texas Labor Code. Thus, the focus of any health care dispute starts with the health care set out in the ODG. Also, in accordance with Division Rule 133.308 (t), “A decision issued by an IRO is not considered an agency decision and neither the Department nor the Division are considered parties to an appeal. In a Contested Case Hearing (CCH), the party appealing the IRO decision has the burden of overcoming the decision issued by an IRO by a preponderance of evidence-based medical evidence.”
Regarding physical therapy, the Official Disability Guidelines & Treatment Guidelines (ODG) provides, in pertinent part:
Recommended. There is strong evidence that physical methods, including exercise and return to normal activities, have the best long-term outcome in employees with low back pain. See also Exercise. Direction from physical and occupational therapy providers can play a role in this, with the evidence supporting active therapy and not extensive use of passive modalities. The most effective strategy may be delivering individually designed exercise programs in a supervised format (for example, home exercises with regular therapist follow-up), encouraging adherence to achieve high dosage, and stretching and muscle-strengthening exercises seem to be the most effective types of exercises for treating chronic low back pain. (Hayden, 2005) Studies also suggest benefit from early use of aggressive physical therapy (“sports medicine model”), training in exercises for home use, and a functional restoration program, including intensive physical training, occupational therapy, and psychological support. (Zigenfus, 2000) (Linz, 2002) (Cherkin-NEJM, 1998) (Rainville, 2002) Successful outcomes depend on a functional restoration program, including intensive physical training, versus extensive use of passive modalities. (Mannion, 2001) (Jousset, 2004) (Rainville, 2004) (Airaksinen, 2006) One clinical trial found both effective, but chiropractic was slightly more favorable for acute back pain and physical therapy for chronic cases. (Skargren, 1998) A spinal stabilization program is more effective than standard physical therapy sessions, in which no exercises are prescribed. With regard to manual therapy, this approach may be the most common physical therapy modality for chronic low back disorder, and it may be appropriate as a pain reducing modality, but it should not be used as an isolated modality because it does not concomitantly reduce disability, handicap, or improve quality of life. (Goldby-Spine, 2006) Better symptom relief is achieved with directional preference exercise. (Long, 2004) As compared with no therapy, physical therapy (up to 20 sessions over 12 weeks) following disc herniation surgery was effective. Because of the limited benefits of physical therapy relative to “sham” therapy (massage), it is open to question whether this treatment acts primarily physiologically, but psychological factors may contribute substantially to the benefits observed. (Erdogmus, 2007) In this RCT, exercise and stretching, regardless of whether it is achieved via yoga classes or conventional PT supervision, helps improve low back pain. (Sherman, 2011) See also specific physical therapy modalities, as well as Exercise; Work conditioning; Lumbar extension exercise equipment; McKenzie method; Stretching; & Aquatic therapy. [Physical therapy is the treatment of a disease or injury by the use of therapeutic exercise and other interventions that focus on improving posture, locomotion, strength, endurance, balance, coordination, joint mobility, flexibility, activities of daily living and alleviating pain. (BlueCross BlueShield, 2005) As for visits with any medical provider, physical therapy treatment does not preclude an employee from being at work when not visiting the medical provider, although time off may be required for the visit.]
Active Treatment versus Passive Modalities: The use of active treatment modalities instead of passive treatments is associated with substantially better clinical outcomes. In a large case series of patients with acute low back pain treated by physical therapists, those adhering to guidelines for active rather than passive treatments incurred fewer treatment visits, cost less, and had less pain and less disability. The overall success rates were 64.7% among those adhering to the active treatment recommendations versus 36.5% for passive treatment. (Fritz, 2007) The most commonly used active treatment modality is Therapeutic exercises (97110), but other active therapies may be recommended as well, including Neuromuscular reeducation (97112), Manual therapy (97140), and Therapeutic activities/exercises (97530). A recent RCT comparing active spinal stabilization exercises (using the GDS or Godelive Denys-Struyf method) with passive electrotherapy using TENS plus microwave treatment (considered conventional physical therapy in Spanish primary care), concluded that treatment of nonspecific LBP using the GDS method provides greater improvements in the midterm (6 months) in terms of pain, functional ability, and quality of life. (Arribas, 2009) In this RCT, two active interventions, multidisciplinary rehab (intensive, bio-psychosocial PT) and exercise (exercises targeted at trunk muscles together with stretching and relaxation), reduced the probability of sickness absence, and were more effective for pain than self-care advice at 12 months. (Rantonen, 2012)
Patient Selection Criteria:Multiple studies have shown that patients with a high level of fear-avoidance do much better in a supervised physical therapy exercise program, and patients with low fear-avoidance do better following a self-directed exercise program. When using the Fear-Avoidance Beliefs Questionnaire (FABQ), scores greater than 34 predicted success with PT supervised care. (Fritz, 2001) (Fritz, 2002) (George, 2003) (Klaber, 2004) (Riipinen, 2005) (Hicks, 2005) Without proper patient selection, routine physical therapy may be no more effective than one session of assessment and advice from a physical therapist. (Frost, 2004) Patients exhibiting the centralization phenomenon during lumbar range of motion testing should be treated with the specific exercises (flexion or extension) that promote centralization of symptoms. When findings from the patient’s history or physical examination are associated with clinical instability, they should be treated with a trunk strengthening and stabilization exercise program. (Fritz-Spine, 2003) Practitioners must be cautious when implementing the wait-and-see approach for LBP, and once medical clearance has been obtained, patients should be advised to keep as active as possible. Patients presenting with high fear avoidance characteristics should have these concerns addressed aggressively to prevent long-term disability, and they should be encouraged to promote the resumption of physical activity. (Hanney, 2009)
Post Epidural Steroid Injections: ESIs are currently recommended as a possible option for short-term treatment of radicular pain (sciatica), defined as pain in dermatomal distribution with corroborative findings of radiculopathy. The general goal of physical therapy during the acute/subacute phase of injury is to decrease guarding, maintain motion, and decrease pain and inflammation. Progression of rehabilitation to a more advanced program of stabilization occurs in the maintenance phase once pain is controlled. There is little evidence-based research that addresses the use of physical therapy post ESIs, but it appears that most randomized controlled trials have utilized an ongoing, home directed program post injection. Based on current literature, the only need for further physical therapy treatment post ESI would be to emphasize the home exercise program, and this requirement would generally be included in the currently suggested maximum visits for the underlying condition, or at least not require more than 2 additional visits to reinforce the home exercise program. ESIs have been found to have limited effectiveness for treatment of chronic pain. The claimant should continue to follow a home exercise program post injection. (Luijesterburg, 2007) (Luijsterburg2, 2007) (Price, 2005) (Vad, 2002) (Smeal, 2004)
Post-surgical (discectomy) rehab: A recent Cochrane review concluded that exercise programs starting 4-6 weeks post-surgery seem to lead to a faster decrease in pain and disability than no treatment; high intensity exercise programs seem to lead to a faster decrease in pain and disability than low intensity programs; home exercises are as good as supervised exercises; and active programs do not increase the re-operation rate. Although it is not harmful to return to activity after lumbar disc surgery, it is still unclear what exact components should be included in rehabilitation programs. High intensity programs seem to be more effective but they could also be more expensive. Another question is whether all patients should be treated post-surgery or is a minimal intervention with the message return to an active lifestyle sufficient, with only patients that still have symptoms 4 to 6 weeks post-surgery requiring rehabilitation programs. (Ostelo, 2009) There is inconclusive evidence for the effectiveness of outpatient physical therapy after first lumbar discectomy. Although evidence from two trials suggested that intervention might reduce disability short-term, and more intensive intervention may be more beneficial than less intensive therapy, pooled results did not show statistically significant benefit.

Recommended. Positive (limited evidence). See also specific physical therapy modalities by name. Use of a home pulley system for stretching and strengthening should be recommended. (Thomas, 2001) For rotator cuff disorders, physical therapy can improve short-term recovery and long-term function. For rotator cuff pain with an intact tendon, a trial of 3 to 6 months of conservative therapy is reasonable before orthopaedic referral. Patients with small tears of the rotator cuff may be referred to an orthopaedist after 6 to 12 weeks of conservative treatment. The mainstays of treatment for instability of the glenohumeral joint are modification of physical activity and an aggressive strengthening program. Osteoarthritis of the glenohumeral joint usually responds to analgesics and injections into the glenohumeral joint. However, aggressive physical therapy can actually exacerbate this condition because of a high incidence of joint incongruity. (Burbank, 2008) (Burbank2, 2008)
Impingement syndrome: For impingement syndrome significant results were found in pain reduction and isodynamic strength. (Bang, 2000) (Verhagen-Cochrane, 2004) (Michener, 2004) Self-training may be as effective as physical therapist-supervised rehabilitation of the shoulder in post-surgical treatment of patients treated with arthroscopic subacromial decompression. (Anderson, 1999) A recent structured review of physical rehabilitation techniques for patients with subacromial impingement syndrome found that therapeutic exercise was the most widely studied form of physical intervention and demonstrated short-term and long-term effectiveness for decreasing pain and reducing functional loss. Upper quarter joint mobilizations in combination with therapeutic exercise were more effective than exercise alone. Laser therapy is an effective single intervention when compared with placebo treatments, but adding laser treatment to therapeutic exercise did not improve treatment efficacy. The limited data available do not support the use of ultrasound as an effective treatment for reducing pain or functional loss. Two studies evaluating the effectiveness of acupuncture produced equivocal results. (Sauers, 2005)
Rotator cuff: There is poor data from non-controlled open studies favoring conservative interventions for rotator cuff tears, but this still needs to be proved. Considering these interventions are less invasive and less expensive than the surgical approach, they could be the first choice for the rotator cuff tears, until we have better and more reliable results from clinical trials. (Ejnisman-Cochrane, 2004) External rotator cuff strengthening is recommended because an imbalance between the relatively overstrengthened internal rotators and relatively weakened external rotators could cause damage to the shoulder and elbow, resulting in injury. (Byram, 2009)
Adhesive capsulitis: For adhesive capsulitis, injection of corticosteroid combined with a simple home exercise program is effective in improving shoulder pain and disability in patients. Adding supervised physical therapy provides faster improvement in shoulder range of motion. When used alone, supervised physical therapy is of limited efficacy in the management of adhesive capsulitis. (Carette, 2003) Physical therapy following arthrographic joint distension for adhesive capsulitis provided no additional benefits in terms of pain, function, or quality of life but resulted in sustained greater active range of shoulder movement and participant-perceived improvement up to 6 months. (Buchbinder, 2007) Use of the Shoulder Dynasplint System (Dynasplint Systems, Inc., Severna Park, MD) may be an effective adjunct “home therapy” for adhesive capsulitis, combined with PT. (Gaspar, 2009)
Active Treatment versus Passive Modalities: See the Low Back Chapter for more information. The use of active treatment modalities instead of passive treatments is associated with substantially better clinical outcomes. The most commonly used active treatment modality is Therapeutic exercises (97110), but other active therapies may be recommended as well, including Neuromuscular reeducation (97112), Manual therapy (97140), and Therapeutic activities/exercises (97530). Physical modalities, such as massage, diathermy, cutaneous laser treatment, ultrasonography, transcutaneous electrical neurostimulation (TENS) units, and biofeedback are not supported by high quality medical studies, but they may be useful in the initial conservative treatment of acute shoulder symptoms, depending on the experience of local physical therapy providers available for referral.

The IRO reviewer, a physical medicine and rehabilitation specialist, pointed out that the Claimant already had the amount of physical therapy that is recommended by the ODG and there was no clear rationale to support exceeding the recommendation. The Claimant should now, according to the ODG, be in a self-directed home exercise program. Although Dr. M wrote a letter stating that the Claimant would benefit from more physical therapy to his neck and back, there was no explanation as to how it would be more beneficial than the therapy he has already received. The Claimant failed to provide evidence-based medicine to overturn the decision of the IRO.
Even though all the evidence presented was not discussed, it was considered. The Findings of Fact and Conclusions of Law are based on all of the evidence presented.
