Individual Factors in Constraint-Induced Movement Therapy after Stroke

Objectives. Constraint-induced movement therapy (CIMT) has been shown to be effective in chronic stroke patients. It is worthwhile to investigate the influence of individual factors for two reasons: to find out whether they influence outcome and to see whether they support the theory underlying CIMT. Methods. Agroupof26 patients were treated with CIMT and followed over 6 months. In total, 14 individual factors were identified. Patients were assessed with 6 tests, including 2 commonly used after stroke (Frenchay Arm Test, 9 Hole Peg Test). Results. There were individual differences, but as a group, patients improved after therapy. There were no individual factors that influenced improvement in more than one test. Conclusions. CIMT is an effective therapy in patients with moderate impairment after stroke, also in tests commonly used in stroke rehabilitation. Factors that could have expected to make a difference on the basis of the theory behind CIMT (e.g., time since stroke, previous therapy, sensory deficit) did not influence results. Patients with hemorrhagic lesions and those with a high level of performance (Motor Activity Log > 2.5) profit as well. Pairwise therapy is as effective as individual therapy.
