PRT results in improvements to muscle strength and some aspects of functional limitation , such as gait speed , in older adults .
However , based on current data , the effect of PRT on physical disability remains unclear .
Further , due to the poor reporting of adverse events in trials , it is difficult to evaluate the risks associated with PRT
BACKGROUND The aim of this systematic review was to quantify the effectiveness of progressive resistance strength training ( PRT ) to reduce  physical disability in older people .
Nursing rehabilitation and exercise strategies in the nursing home.
BACKGROUND The purpose of this study was to evaluate how weight training or nursing-based rehabilitative care programs in nursing homes impact on resident performance of Activities of Daily Living ( ADL ) and objectives tests of physical performance . METHODS This study involved a quasi-experimental control , longitudinal comparison of functional status over a 10-month period , where baseline status was adjusted through a weighting procedure based on functional status , cognitive status , and age . All residents from six residential care nursing home facilities were eligible except those with a terminal prognosis , a projected stay of less than 90 days , or with health complications that prohibited contact . Homes were placed into matched triplets based on patient characteristics : two members of each triplet were r and omly design ated to be experimental sites , the third became the control site . Baseline data were available for 468 subjects , follow-up for 392 .  ADL self-performance measures derived from the Minimum Data Set , including indicators of early loss ADL , locomotion , and late loss ADL ; a number of objective functional tests ( including measures of balance , power , and endurance ) ; and mood state as measured by the Geriatric Depression Scale . RESULTS Mean ADL values in the two experimental groups declined at a significantly lower rate than did rates for the controls . Functional decline was also lower in more specific measures : locomotion , early loss ADL , and late loss ADL . CONCLUSIONS With both interventions , facilities were able to implement a broad-based intervention that result ed in a significant reduction in ADL decline rates . A facility-wide nursing rehabilitation program can play a useful role in reversing functional decline , helping residents to maintain their involvement in a broad spectrum of ADL activities
