Aging is associated with loss of muscle strength and a serious import of physical disability. Treatment of age-related physical disability should focus on the prevention of the condition rather than the consequences. Need to modify daily tasks is an early sign of future mobility disability. Many older adults who utilize daily task modifications report no mobility difficulty. Neglect to self-report task modification may delay intervention. Identifying objective marker of task modification will help to identify task modifiers.

Sampling Method:   Probability Sample
Study Population
fifty-three community dwelling male (21) and female (32) older adults (76.4±5.2 years) were observed performing a chair rise, negotiating stairs, kneeling from a standing position, and rising from supine to stand.

Inclusion Criteria:

  • 65 years and older
  • no major health problems

Exclusion Criteria:

  • Participants were not invited for further testing if they were unable to understand basic English, or reported health problems that contraindicated strength and functional testing.
  • Examples of such exclusion criteria included severe orthopedic limitations, uncontrolled cardiovascular or metabolic diseases, recent/unhealed fractures, disorders with highly variable course (e.g. multiple sclerosis), severe cognitive impairments, or a score of 20/30 or below on the Mini-Mental State Examination (MMSE) test (Folstein,M.F. 1975; Jensen,J. 2003;Tombaugh,T.N. 1992;).
