Objective To Study the stress distribution of the lower cervical spine in the flexionandextension movement.
目的:探讨下颈椎屈伸运动对其应力分布的影响。
2
Elbow flexion, wrist flexionandextension, and metacarpophalangeal joint flexionandextension were not impaired.
但是肘关节屈曲、腕关节的屈曲和伸展、掌指关节的屈曲和伸展未受影响。
3
Repeated traction and compression on the ulnar nerve during elbow flexionandextension is the anatomical foundation of ulnar nerve compression at the elbow.
