Soleus H-reflex gain in elderly and young adults: modulation due to body position.
The control of posture and balance in the elderly is a primary health concern. Postural instability directly leads to a greater incidence of falling in the elderly population. One important neuromuscular mechanism instrumental in the control of posture and balance is the reflex system. The purpose of this study was to examine the gain of the soleus H-reflex in young and elderly adults in two different body positions: standing and prone. ⋯ The results demonstrate different control strategies for young and elderly subjects between prone and standing body positions.
