Article Abstract:
The impact of aging on sensorimotor levels of propriomuscular function was analyzed by measuring reflex and postural responses in young and elderly subjects. The results showed that reflex responses to vibration of the biceps and triceps brachii and deep reflexes of the lower limbs were not dependent on age. However, the intensity of postural responses to the same vibratory stimulation applied to the soleus and the tibialis anterior muscles decreased both with age and when the use of vision was possible.

Article Abstract:
Research indicates that the phase-dependent modulatory capacity of the elderly could be influenced by psychological or physiological factors, with older people maintaining a limited capacity for modulatory ability. Younger adults were found to have greater capacity to modulate burst magnitude than the elderly, although the postural responses of the elderly incorporated phase-dependent modulatory abilities of the burst duration, onset latency and occurrence of forward slip simulations.

Article Abstract:
Stephen N. Robinovitch and associates conducted a study on the role of perception with regards to the reaching abilities of the elderly and younger adults. They concluded that the restricted reaching abilities of the elderly may be related to the lack of awareness of their movement abilities which may result in falls. Their conclusion that younger adults may invoke caution when underestimating their reaching abilities is open to alternative interpretations.
