Abstract:
OBJECTIVE: To investigate the effects of modified constraint- induced movement therapy (CIMT) on motor function and cortical activation in children with hemiplegic cerebral palsy (CP). METHOD: Five children with hemiplegic cerebral palsy were studied with Jebsen hand function test and quality of upper extremity skills test (QUEST), dynamic electromyography (EMG), and single photon emission computed tomography (SPECT) at rest before and after the CIMT period. Children were treated with a 4-week protocol of modified CIMT, consisting of twice-weekly 2-hour sessions of structured activities and a home program for non-treatment days. Children wore orthoses on their less affected upper extremities for 6 hours per day, during which time they were engaged in play, functional activities and 2-hour protocol of motor tasks. RESULTS: Improvements in upper-extremity function were found in Jebsen hand function test and QUEST. Increased muscle activities in elbow extensors were observed in dynamic EMG during affected hand grip. In right hemiplegic patients, regional cerebral perfusion increased in right Brodmann area (BA) 3 and lentiform nucleus. In left hemiplegic patients, regional cerebral perfusion increased in right BA 6, 9, 21, left BA 19 and left cerebellum, but decreased in left BA 11. CONCLUSION: Modified CIMT appears to change local cerebral perfusion in areas known to participate in movement planning and execution. These changes might be a sign of cortical activation after CIMT in the children with hemiplegic cerebral palsy. Results of this study suggest that modified CIMT may be an effective way of treating children with hemiplegic CP.
