Constraint-induced movement therapy for severe upper-extremity impairment after stroke in an outpatient rehabilitation setting: a case report.

PURPOSE

Laboratory studies confirm that constraint-induced movement therapy (CIMT) improves upper-extremity (UE) function after stroke. Due to strict patient criteria and the intensive resources required, CIMT has been slow to become part of rehabilitation practice. Our purpose was to determine the feasibility and effectiveness of an adapted experimental protocol within an outpatient clinical setting for a patient with moderate to severe UE impairment who did not meet traditional CIMT criteria.

PATIENT DESCRIPTION

AJ, a 16-year-old male, experienced a left middle cerebral artery ischemic stroke due to carotid artery dissection one year before beginning CIMT. He demonstrated some proximal movement but no wrist or finger extension. He had received intensive rehabilitation for 12 months prior to beginning CIMT.

INTERVENTION

Two occupational therapists and two physiotherapists collaborated to provide CIMT task training for 6 hours daily for 2 weeks. A knitted mitten extending to the elbow restrained the less-involved UE during 90% of waking hours. Tasks were tailored to AJ's interests, with the goal of integrating his affected UE into his behavioural repertoire. MEASURES AND OUTCOMES: After 2 weeks of CIMT, AJ improved in all measures (grip and lateral pinch strength, Action Research Arm Test [ARAT], and Box and Block Test) except the Chedoke McMaster Impairment Inventory. Greatest gains were seen at 6 months in the ARAT and Box and Block Test, which coincided with patient and family reports of AJ's using his arm in everyday functional tasks.

IMPLICATIONS

Shared workload, emphasis on relevant functional tasks, and complete family participation likely influenced the success of CIMT. Our findings suggest that the strict CIMT criteria used in previous studies may exclude patients who might benefit from the treatment. Controlled trials should be undertaken to examine the effects of CIMT in patients with moderate to severe UE impairment.
