Do FCU and ECU muscle architecture in children with hemiparetic cerebral palsy affect wrist functionality

Purpose In individuals with cerebral palsy (CP), wrist flexor and extensor muscles can have impaired tonus, strength, posture, and range of motion. Muscle force and movement generating capacity are related to muscle architecture. The purpose of the study was to measure muscle morphology of the flexor (FCU) and extensor carpi ulnaris (ECU) muscles and compare it with strength and passive stiffness in affected and unaffected forearms of children with hemiparetic CP.
