Design outcomes

Primary

Measure	Time frame
1. Intra- and inter-rater reliability of slow and fast stretches are measured using the hand-held device at baseline 2. Validity of passive ankle joint stiffness is measured comparing the hand-held device compared to the golden standard stationary dynamometer at baseline 3. Differentiation of passive ankle joint stiffness between healthy subjects and subjects with CP is measured using the hand-held device at baseline	—
