We have investigated the effects of the low pressure environment (510mmHG) on the motor function in human. We have gotten some conclusions as below.
1) There are no significant effects on dorsal muscle function, dorsal muscle power and grasping power. 2) The significant decline of quick active function as finger-nose test was shown in the low pressure environment. 3) The significant delay of ulnar motor nerve conduction velocity was shown in the low pressure environment especially after loading exercise.
