Two groups of elderly females were studied to assess the importance of manual ability as a component of independent self-care. A survey instrument was designed which consisted of timing empiric tasks chosen to approximate skills needed to conduct daily activities. Comparison of the mean times for almost every task reveals differences of such magnitude that the populations sampled are totally different by the criteria of manual ability. Many hypotheses are consistent with this observation. Regardless of which hypothesis will prove most likely, the result will be germane to geriatric medicine.
