PURPOSE To examine the results of repeated episodes of 21-day pediatric constraint induced movement therapy (PCIMT) paired with gross motor training (GMT). METHODS Nineteen children, age 14 months - 6 years with unilateral upper extremity impairment enrolled in this cohort study to receive repeated episodes of 21 day PCIMT-GMT. Outcome measures included the Peabody Developmental Motor Scales-2 (PDMS-2), the Assisting Hand Assessment (AHA) and the Canadian Occupational Performance Measure (COPM). RESULTS All children demonstrated improvement in raw scores following each episode of PCIMT-GMT with a statistically significant change in the least squares estimated mean for all measures except the PDMS-2 total motor raw score and gross motor quotient for the preferred hand in the fourth episode (p< 0.05). Gains were noted on the Scaled Score for the AHA for 39/39 episodes, all greater than the smallest detectable difference. COPM Performance and Satisfaction scores for 17/17 episodes were above the clinically meaningful threshold. Additional improvements in scores were noted in all children with each repeated episode. CONCLUSION Children with unilateral upper extremity impairment demonstrate improvements in fine motor, gross motor, and bimanual skills, along with functional changes in participation in daily life, following PCIMT-GMT. Participation in repeated episodes can lead to further improvements.
