Stretching and Splinting Devices for the Treatment of Joint Stiffness and Contractures

Policy Number: MP-346

Latest Review Date: December 2022

Category:  DME                                                                    

POLICY:

Dynamic low-load prolonged-duration stretch (LLPS) devices for use on the ankle, knee, elbow, wrist, finger or jaw may be considered medically necessary for a period of up to 4 months in the following clinical setting:

  • As a treatment for loss of motion from a contracture as part of a formal rehabilitation program or when a formal rehabilitative program is not feasible or has failed to provide benefit.

Only one device is covered per affected area, i.e., separate devices for flexion and extension for the same area are considered not medically necessary.

The use of dynamic LLPS devices for any other joint or condition including, but not limited to toe, foot, shoulder and forearm disorders, chronic joint stiffness, chronic or fixed contractures, rheumatoid arthritis or plantar fasciitis are considered investigational. 

Dynamic low-load prolonged-duration stretch (LLPS) devices are non-covered when used as a part of post-operative care.

The use of dynamic, extension/flexion devices with active resistance control are considered investigational.

The use of carpal tunnel dynamic splinting as a non-surgical rehabilitative modality for the treatment of carpal tunnel syndrome is considered investigational.

For Bi-directional static progressive (SP) stretch devices and patient-actuated serial stretch (PASS) devices, please refer to Medical Policy 578-Patient-actuated End Range Motion Stretching Devices.

DESCRIPTION OF PROCEDURE OR SERVICE:

Mechanical stretching devices differ from continuous passive motion devices in that they are nonmotorized and include the following types: low-load prolonged-duration stretch (LLPS) devices. Mechanical stretching devices are generally proposed as an adjunct treatment to PT and/or exercise.

LLPS devices, also referred to as dynamic splinting, permit active and passive motion with elastic traction within a limited range and maintain a set level of tension by means of incorporated springs. Examples of LLPS devices include, but may not be limited to, Advance Dynamic ROM, Dynasplint, EMPI Advance Dynamic ROM, Proglide Advance Dynamic ROM, LMB Pro-Glide, SaeboFlex, SaeboReach, Stat-A-Dyne and Ultraflex.

Jaw mobility mechanical stretching devices are suggested for use in the treatment of temporomandibular joint (TMJ) disorders, trismus or other conditions in which jaw movement is limited. Examples of this type of mechanical stretching device include, but may not be limited to, TheraBite Jaw Motion Rehabilitation System, Dynasplint Trismus System or Orastretch.

KEY POINTS:

Literature review through December 2022.

SUMMARY OF EVIDENCE:

The use of low-load prolonged stretch (LLPS) splinting devices are proven for improvement of range of motion after surgery or injury when physical therapy alone has not been effective. The use is limited to joints of the jaw, ankle, knee, elbow, finger, and wrist. The evidence is sufficient to determine that the technology results in an improvement in the net health outcome.

The use of low-load prolonged stretch (LLPS) splinting devices in joints other than those mentioned above and prophylactic use has not been proven at this time. Effectiveness with chronic or long-term fixed contractures has not been proven at this time. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.

KEY WORDS:

Joint stiffness, contracture, dynamic low-load prolonged-duration stretch (LLPS) devices, plantar fasciitis, Dynasplint System, Dynasplint Trismus System, EMPI Advance Dynamic ROM, LMB Pro-Glide,TheraBite®, OraStretch™

APPROVED BY GOVERNING BODIES:

Mechanical stretching devices are classified by the FDA as Class 1 medical devices.  Class 1 devices have the least amount of regulatory control; manufacturers of these devices are exempt from premarket notification procedures and are not required to provide safety and effectiveness data prior to marketing.  Numerous mechanical stretch devices have been developed and are generally categorized as static progressive (SP) stretch devices, low-load, prolonged-duration stretch (LLPS) devices, and patient-actuated serial stretch (PASS) devices.

BENEFIT APPLICATION:

Coverage is subject to member’s specific benefits.  Group specific policy will supersede this policy when applicable.

ITS: Home Policy provisions apply

FEP contracts: FEP does not consider investigational if FDA approved and will be reviewed for medical necessity. Special benefit consideration may apply.  Refer to member’s benefit plan.

This medical policy is not an authorization, certification, explanation of benefits, or a contract. Eligibility and benefits are determined on a case-by-case basis according to the terms of the member’s plan in effect as of the date services are rendered. All medical policies are based on (i) research of current medical literature and (ii) review of common medical practices in the treatment and diagnosis of disease as of the date hereof. Physicians and other providers are solely responsible for all aspects of medical care and treatment, including the type, quality, and levels of care and treatment.

This policy is intended to be used for adjudication of claims (including pre-admission certification, pre-determinations, and pre-procedure review) in Blue Cross and Blue Shield’s administration of plan contracts.

The plan does not approve or deny procedures, services, testing, or equipment for our members. Our decisions concern coverage only. The decision of whether or not to have a certain test, treatment or procedure is one made between the physician and his/her patient. The plan administers benefits based on the member’s contract and corporate medical policies. Physicians should always exercise their best medical judgment in providing the care they feel is most appropriate for their patients. Needed care should not be delayed or refused because of a coverage determination.

As a general rule, benefits are payable under health plans only in cases of medical necessity and only if services or supplies are not investigational, provided the customer group contracts have such coverage.

The following Association Technology Evaluation Criteria must be met for a service/supply to be considered for coverage:

1. The technology must have final approval from the appropriate government regulatory bodies;

2. The scientific evidence must permit conclusions concerning the effect of the technology on health outcomes;

3. The technology must improve the net health outcome;

4. The technology must be as beneficial as any established alternatives;

5. The improvement must be attainable outside the investigational setting.

Medical Necessity means that health care services (e.g., procedures, treatments, supplies, devices, equipment, facilities or drugs) that a physician, exercising prudent clinical judgment, would provide to a patient for the purpose of preventing, evaluating, diagnosing or treating an illness, injury or disease or its symptoms, and that are:

1. In accordance with generally accepted standards of medical practice; and

2. Clinically appropriate in terms of type, frequency, extent, site and duration and considered effective for the patient’s illness, injury or disease; and

3. Not primarily for the convenience of the patient, physician or other health care provider; and

4. Not more costly than an alternative service or sequence of services at least as likely to produce equivalent therapeutic or diagnostic results as to the diagnosis or treatment of that patient’s illness, injury or disease.
