Construct validity, reliability, and responsiveness of the Wrist Position Sense Test for use in children with hemiplegic cerebral palsy

Abstract

Introduction: We investigate the construct validity, test re-test reliability, and responsiveness of the Wrist Position Sense Test (WPST) for children with hemiplegic cerebral palsy (CP). Methods: Twenty-eight children with spastic hemiplegic CP [mean age 10.8 years; SD 2.4 years] and 39 typically developing (TD) children [mean age 11 years; SD 2.9 years] participated in a cross-sectional study to investigate construct validity and association with an upper limb activity measure, the Box and Block Test (BBT). Twenty-two TD children were tested at a second time-point to examine reliability. Test responsiveness was determined by random allocation of 17 children with CP to a treatment (n = 10) ..
