In spastic cerebral palsy, there are interrelated neuromuscular deficits that can affect ankle joint control, including impaired selective voluntary motor control, muscle weakness, spasticity, and shortened muscle-tendon units. As a result, it is important to assess ankle joint control in children with spastic cerebral palsy. Clinicians need valid, reliable, and practical methods to assess ankle joint control. The aim of this study is to evaluate the validity and reliability of the Foot-taping Test in children with spastic cerebral palsy.
