Abstract
Objective To explore the gaits of patients with club foot undergoing anterior tibialis transfer by three-dimensional (3D)gait analysis through a biomechanical approach. Methods Twenty patients under-going anterior tibialis transfer were recruited between July 201 1 and July 201 4.There were 1 5 males and 5 fe-males with an average age of 6.3(5 ~8)years.All patients were evaluated by 3D gait analysis motion analysis system (Motion Inc.,USA).Three-step lengths at constant gait speed were measured.Fifteen points were set up around pelvis,hip,knee and ankle and connected for constructing 3D dynamic images. Results After an-terior tibialis transfer,no significant differences existed in walking speed,cadence and step compared with pre-operative values.Foot abduction of postoperative children significantly improved compared with preoperative sta-tus.Preoperative and postoperative muscle activity of anterior tibialis had no significant change and it stayed ac-tive post-operation.The postoperative moving line of affected-side lower extremities improved compared with pre-operative status. Conclusions 3—D gait analysis can clearly evaluate bilateral lower extremity joint motions in all planes in patients with club foot undergoing anterior tibialis transfer.Also it helps us understand accurately the changes in muscle activity of anterior tibialis and biomechanics of ankle joint.Therefore deformity correction of patients with club foot undergoing anterior tibialis transfer may be fully evaluated through 3—D gait analysis.关键词
