High test-retest reliability was found for the Function component , while results for the Disability component were more variable .
Conclusions There is extensive evidence to support the construct validity and sensitivity to change of the LLFDI among various clinical population s of community-dwelling older adults .
Background The choice of measure for use as a primary outcome in geriatric research is contingent upon the construct of interest and evidence for its psychometric properties .
The Late-Life Function and Disability Instrument ( LLFDI ) has been widely used to assess functional limitations and disability in studies with older adults .
The primary aim of this systematic review was to evaluate the current available evidence for the psychometric properties of the LLFDI .
Sit-to-stand as home exercise for mobility-limited adults over 80 years of age--GrandStand System may keep you standing?
PURPOSE To compare the effects of functional home exercise of repeated sit-to-st and s with low-intensity progressive resistance training , on performance measures in mobility-limited adults over 80 years of age . SETTING Participants ' homes . DESIGN Community-dwelling older adults > or = 80 years of age were invited to participate in a r and omised controlled clinical trial . Baseline and outcome measures were : comfortable gait velocity , 30-s chair-st and test , 15-s step test , Berg Balance Scale , Modified Falls Efficacy Scale and the Late-Life Function and Disability Instrument-function component . Participants r and omised to the intervention group performed repeated sit-to-st and s using a Gr and St and System ; a biofeedback device that recorded and displayed the number of repetitions performed . Participants r and omised to the control group performed knee extensions using ankle cuff weights . Both groups performed the exercises daily for 6 weeks . RESULTS Sixty-six older adults took part . The intervention group had a statistically significant improvement in Berg Balance Scale mean score , 1.67 + /- 2.64 points , P = 0.001 ( control group 0.73 + /- 3.63 points , P = 0.258 ) , indicating an improvement in balance over the 6-week exercise period . There was no statistically significant effect of either intervention on the other outcome measures . CONCLUSIONS In a highly variable population of older adults with mobility limitations , low-intensity functional home exercise of repeated sit-to-st and s using the Gr and St and System improved Berg Balance Scale score while low-intensity progressive resistance training did not . While statistically significant , the improvement in Berg Balance Scale score was modest raising the issue of what extent of change in score is clinical ly significant in this population
