The appearance of joint was satisfactory, stable. The flexion deformity was disappeared at 2 years after operation with extended fingers activities. The thumb extension and opposition function were good, and the finger joint motion of the first metacarpal was normal with 84.6%(11/13) subjective satisfaction rate.
③Patient's condition was judged by stroke scoring (including 7 items: status of mind,language expression,shoulder joints of upper limbs,articulationes digitorum manus,femoral articulation,articulationes digitorum pedis and comprehensive function. There were 5 grades in all with the score ranged 0- 4 points,and the highest score signified the lightest disease).
The flexion and extension of phalangeal joints was normal in 13 cases besides 5 cases of originally existed extensor tendon adhesion and contracture of accessory ligament of metacarpophalangeal joints.
The axial line of the flap was the line from ulnar side of the head of the fifth metacarpal bone to the pisiform level. The revolving point of the flap pedicle was 0 5～1 cm near the proximal end of the metacarpal |phalangeal joint.
First, we manufacture a power assist device which compensates the bending moment exerted at a human finger joint utilizing a standing-wave-type ultrasonic motor.
The proposed CVT is remarkably simple and enables a finger joint to exert a large fingertip force and to move quickly.
Finger joint movement sensitivity of non-cutaneous mechanoreceptor afferents in the human radial nerve
In conclusion, the present study established a method for recording the evoked responses to the brisk passive movement of the finger joint, which mainly reflect the dynamic aspects of proprioception mediated through muscle afferent.
Furthermore, it was possible to make this estimate without determining any of the finger joint angles.
