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 .
Wii‐Hab for Pre‐Frail Older Adults
Purpose : To examine the effectiveness of a novel intervention aim ed at decreasing indices related to frailty through systematic , Progressive Functional Rehabilitation ( PFR ) . Methods : Pre‐frail volunteers were recruited to participate in a 15 week exercise intervention or control group .  Those who met study criteria and consented were r and omized into one of three groups : control , seated exercise , or Wii ® ‐fit . Test measures were completed before and after the 15 week intervention period on all participants . Measures included : Senior Fitness Test , Body Weight , Balance Efficacy Scale , CHAMPS , Late‐Life Function and Disability Index , MOS SF‐36 . Attendance was also recorded . Results : There were improvements on several of the measures included in the Senior Fitness Test including chair st and s , arm curls , step 2 , six minute walk , sit and reach , and the timed up and go . A few participants did lose weight . All of the differences reflected improved physical functional status in the seated exercise or Wii‐fit groups compared with the control group . Discussion : Increased physical activity was beneficial for all who participated . There were improvements in physical performance scores on several of the measures on the senior fitness test in both the seated exercise and Wii‐fit groups . Participants in the Wii‐fit group also showed improvement in their reported caloric expenditure and balance confidence . Conclusion : This pilot study suggests a rehabilitation effect that was similar to the effect of community based senior fitness classes . A home video game console system with weight vest could be an effective alternative for pre‐frail senior adults to group exercise classes
