Abstract
A comparison of hinged versus solid ankle orthoses in a child with moderate spastic diplegia demonstrated that solid ankle braces blocked needed foot and ankle mobility. The loss of movement forced the child to use extraneous movement patterns in order to move the upper body over the foot. These iatrogenically induced deviations were considered reasons for surgery. When ankle and foot mobility were increased by the use of hinged ankle braces, the gait improved and with physical therapy the reasons for surgery were removed. This case study shows that significant biomechanical changes can be achieved by simply switching from solid to articulated or hinged ankle-foot orthoses.
