| 内容記述 | To test our hypothesis that somatosensory inputs inhibit the soles Hoffmann(H-reflex) circuit during upright standing, ten subjects were investigated under the head-out water immersion (HOWI) condition. Subjects maintained an upright standing without any activity in the soleus, tibialis anterior and vastus lateralis muscles. Testing was conducted (1)dry condition, (2)neck level water immersion to reduce the gravitational effect by 95% by buoyancy (HOWI condition) and (3)95% of the subject’s body weight bearing under HOWI condition (weight-load condition). The test soleus H-reflex and motor (M) response was elicited at a stimulation intensity of 1.05 times the motor threhold. No significant differences in the recruitnebt profile of the M response were observed. Yhe amplitude of the H-reflex normalized by the maximum M response (M_<max>) was significantly different, even while the stimulation intensity remained constant. The H-reflex in the HOWI was significantly stronger as compared with its strength in the HOWI condition. It was concluded that somatosensory inputs due to gravity exert an inhibitory effects on the soleus H-reflex circuit during upright standing in humans. | |||||
