title: Kinematic and neuromuscular changes of the gait pattern after Achilles tendon rupture.
abstract: After long immobilization periods in equinovalgus with operated Achilles tendon rupture, long-lasting changes of motor patterns in functional movement can be expected. In the present study, possible alterations in gait pattern have been analyzed based on kinematic and neuromuscular parameters. Ten patients 1 year after surgery and a healthy control group performed 10 gait cycles in natural walking cadence. Ankle motion, pressure distribution, and electromyographic data were recorded and analyzed in defined phases. Kinematic and neuromuscular changes are still evident 1 year after surgery with a temporal phase shift and a neuromuscular deficit of the lateral gastrocnemius muscle. The objective of rehabilitation should be the facilitation of the temporal innervation pattern of the lateral gastrocnemius muscle in the functional movement.
