Constraint‐induced movement therapy versus bimanual intensive therapy in children with hemiplegia showing low/very low bimanual functional performance: A randomized clinical trial

Abstract

AbstractIntroductionChildren with infantile hemiplegia with low or very low bimanual functional performance have great impediments to spontaneously use their affected upper limb, which affects their performance of day‐to‐day activities and their quality of life.ObjectiveTo determine whether the order of application and the dose of modified constraint‐induced movement therapy within a combined (hybrid) protocol influences the results of bimanual functional performance of the affected upper limb and the quality of life of children with congenital hemiplegia (5 to 8 years old) with low/very low bimanual functional performance.DesignSingle‐blinded randomized controlled trial.ParticipantsTwenty‐one children with congenital hemiplegia (5 to 8 years old) were recruited from two public hospitals and an infantile hemiplegia association in Spain.InterventionsThe experimental group (n = 11) received 100 hours of intensive therapies for the affected upper limb: 80 hours of modified constraint‐induced movement therapy and 20 hours of bimanual intensive therapy. The control group (n = 10) received the same dose with 80 hours of bimanual intensive therapy and 20 hours of modified constraint‐induced movement therapy. The protocol was provided 2 hours per day, 5 days per week, for 10 weeks.Outcome MeasuresThe primary outcome was bimanual functional performance, measured with the Assisting Hand Assessment, and the second outcome was quality of life, measured with the Pediatric Quality of Life Inventory Cerebral‐Palsy module (PedsQL v. 3.0, CP module). Four assessments were performed: Weeks 0, 4, 8, and 10.ResultsThe experimental group obtained an increase of 22 assisting hand assessment (AHA) units at week 8 with the application of modified constraint‐induced movement, in contrast with the control group, which obtained an increase of 3.7 AHA units after bimanual intensive therapy. At week 10, the control group showed its greatest increase in bimanual functional performance, with 10.6 AHA units after modified constraint‐induced movement therapy. Regarding quality of life, the greatest improvement occurred after modified constraint‐induced movement, with 13.1 points in the experimental group (80 hours) and 6.3 points in the control group (20 hours). The protocol interaction was statistically significant for bimanual functional performance (p = .018) and quality of life (p = .09).ConclusionsModified constraint‐induced movement therapy is more beneficial than bimanual intensive therapy for improving upper limb functioning and quality of life in children with congenital hemiplegia showing low/very low bimanual performance.ClinicalTrials.gov IdentifierNCT03465046.
