This article is about physical therapy in carpal tunnel syndrome. Physical therapists and occupational therapists are involved in the assessment and intervention process with clients with carpal tunnel syndrome (CTS). Within the area of intervention, PTs and OTs provide education; symptom management techniques such as splinting; and modification of specific tasks, equipment and environment. Assessment Tinel's sign and Phalen's tests can be used to assess for CTS. They may be administered by the physical therapist (PT) or occupational therapist (OT). Tinel's sign involves tapping at the volar wrist while Phalen's test involves maintaining maximum wrist flexion for 60 seconds. In both tests, a positive sign is indicated by numbness, tingling or pain in the thumb, index and half of the middle finger. The presence of positive Tinel sign, Phalen sign, Flick sign, or Upper limb neural tension test independently have weak evidence for diagnosing CTS. However, when these provocative tests are combined, they are far more reliable for diagnosing this condition. Following positive signs, the PT or OT may perform manual muscle testing for grip and pinch strength and assess range of motion. The clinician may perform a detailed step-by-step breakdown of what's involved in the activity to look at the specific tasks that could be affected by or be contributing to CTS symptoms. For example, the PT or OT may analyze the activity of cooking. They may find, for example, that repetitive lifting of heavy skillets is a contributing factor to the individual's CTS symptoms. They may also observe the environment in which the activity is being performed and identify risk factors and compensatory strategies. Intervention PTs and OTs provide protective and corrective non-surgical measures for CTS and focus intervention on the person's physical abilities, environment, and the activities they engage in. Intervention has an emphasis on enabling function in self-care activities, leisure and paid or unpaid work. At the level of person, therapists can provide education and/or direct intervention for physical symptom treatment and management. At the levels of environment and occupation, PTs and OTs provide education and modifications related to the method of task completion, including equipment and tools used, and the setting in which it is being performed. PTs and OTs who provide intervention for individuals with CTS may also be hand therapists. In addition Physical Therapists may have residency and fellowship training concerning the treatment of hands. Bash & Farber state that to become a
