Effects of upper extremity surgery on activities and participation of children with cerebral palsy: a systematic review

AIM: To evaluate and synthesize the evidence for effects of upper extremity surgery (UES) on activities and participation of children and adolescents with cerebral palsy (CP). METHOD: The databases MEDLINE, Embase, and PsycINFO were searched for publications up to September 2018. Studies included were comparative studies with or without concurrent comparison groups or case series with pretest/posttest outcomes with a minimal sample size of 10 participants; those that reported the effects of UES with a follow‐up time of at least 5 months; those including patients diagnosed with CP aged up to 20 years; and those that used a validated activity‐based instrument. Risk of bias was assessed using the ROBINS‐I (Risk Of Bias In Non‐randomised Studies ‐ of Interventions) tool and quality assessment was performed using the Grading of Recommendations Assessment, Development and Evaluation. RESULTS: Twelve studies, involving 310 children and adolescents, were included. The ability and perception of the patient to use the hand(s) and perform activities (measured with the Shriners Hospital Upper Extremity Evaluation, Assisting Hand Assessment, and House Functional Classification) improved significantly after UES. The quality of evidence was very low for each of the activity outcomes of interest. INTERPRETATION: The very low evidence prohibits recommendations on the use of UES to guide clinical practice. More high‐quality comparative studies are needed to obtain better insight into the effects of UES on activities and participation. WHAT THIS PAPER ADDS: Low quality of evidence for effects of upper extremity surgery (UES) on activities and participation. Limited evidence for improvement in activities and participation after UES.
