DESCRIPTION OF PROCEDURE OR SERVICE:

Constraint-induced movement therapy (CIMT), also known as constraint induced therapy (CIT) or forced use movement therapy, is a therapeutic approach to rehabilitation of movement after stroke or other neurologic events.  CIMT has been used to improve motor function in patients following CVA.  The intensity and schedule of delivery of CIMT is different from that of traditional physical therapy.  CIMT involves a technique of restraining the unimpaired limb and forcing the use of the impaired limb during normal daily activities and rehabilitation exercises.  The non-paretic upper extremity is secured in a sling for 90% of waking hours, while the paretic arm receives intensive training in a variety of tasks six hours per day for two to three weeks.  Pediatric CIT may also be referred to as ACQUIREc Therapy.

CIMT has been used in patients with chronic and subacute CVA, chronic traumatic brain injury, incomplete spinal cord injury, cerebral palsy, fractured hip, phantom limb pain, as well as musicians with focal hand dystonia.  The exact mechanism by which CIMT produces its therapeutic effect is not known, but imaging studies suggest that use-dependent cortical reorganization may occur after CI therapy.

Recently, Constraint Induced Language Therapy (CILT) or Constraint Induced Aphasia Therapy (CIAT) has been used to treat patients with aphasia.  CILT differs from usual aphasia treatment approaches in that no compensatory nonverbal communications (e.g., gesture, drawing, and writing) are allowed during the language activities.  Improved verbal responses are the goal of treatment.  Proponents of this therapy hypothesize that by limiting the patient’s use of compensatory communications or even giving up on the message altogether during the therapy session, the brain is forced to adapt and find an alternate way to express the idea, i.e., verbalization and spoken words.  Treatment is intense and frequent lasting six hours per day for five days per week. 

KEY POINTS:

Summary of Evidence:

There continues to be little evidence to evaluate the efficacy of CIMT for motor disorders. Among three small controlled trials published to date, there were trends supporting a treatment effect. Because the methods and outcomes used varied considerably among these trials, it is unclear which techniques, if any, are clinically useful.

A literature search identified one randomized controlled trials for using CILT to treat aphasia. The authors of this trial could not rule out that the possibility that conventional therapy performed in a massed-practice fashion also could result in pronounced behavioral improvement within a few days. In addition, small case series reporting on a limited number of participants with short follow-up were noted. There is little evidence to evaluate the efficacy of CILT for aphasia.

Finally, there is no documented standardized protocol for performing CIMT.  Future studies are needed to determine the best protocol for sustained results.

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.
