The aim of this study was to clarify a knack for skillful winding operation by a professional of braiding. We recorded kinematic and electromyographic (EMG) data simultaneously using three high-speed cameras (125Hz) and a 6-channnel surface EMG system. EMG activity was recorded from selected superficial muscles of the left upper limb-flexor carpi radialis, extensor digitrum, flexor carpi ulnaris, extensor carpi radialis, biceps brachii, and triceps brachii muscles. Kinematic characteristics of motion of the left upper limb were identified by wrist (palmar) flexion-extension, ulnar-radial flexion, pronation-supination of the forearm, and elbow flexion-extension. Compared to the parallel-winding method in which limb movement was very slowly at elbow and wrist joints, in the cross-winding method each joint moved repeatedly with short quick steps. In addition, whereas EMG activity of each muscle in the parallel-winding method was little, in the cross-winding method EMG burst of the biceps and triceps brachii appeared alternately, and the pattern of EMG burst of the BB and TB matched those of the kinematic characteristics. These results indicate that controlling the proximal muscles appears to be important for the skillful cross-winding method.
