Effects of constraint-induced therapy on hand function in children with hemiplegic cerebral palsy

Pediatr Phys Ther. 2001 Summer;13(2):68-76.


Purpose: The effects of constraint-induced therapy on hand function of the involved upper extremity were examined in three children with hemiplegic cerebral palsy.

Methods: In these case reports, the noninvolved upper extremities of the children were constrained six hours daily for 14 consecutive days. Hand function, strength, sensation, and fingertip force coordination were examined pre- and postintervention.

Results: The results indicated that there was an improvement in hand function for two of the three children and an improvement in two-point discrimination threshold values for all children. While there was no consistent change in fingertip force coordination during precision grip across children, one child demonstrated a consistent decrease in duration of temporal phases of fingertip force coordination and two children demonstrated a reorganization of the grip-lift synergy of the involved hand.

Conclusion and clinical implications: Improvement in hand function is not captured by any one measure. The effectiveness of this intervention is promising but may be dependent on the severity of the impairment.
