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 .
Effects of Telerehabilitation on Physical Function and Disability for Stroke Patients: A Randomized, Controlled Trial
Background and Purpose — To determine the effect of a multifaceted stroke telerehabilitation ( STeleR ) intervention on physical function , and secondarily on disability , in veterans poststroke . Methods — We conducted a prospect i ve , r and omized , multisite , single-blinded trial in 52 veterans with stroke from 3 Veterans Affairs medical centers . Veterans with a stroke in the preceding 24 months were r and omized to the STeleR intervention or usual care .  The STeleR intervention consisted of 3 home visits , 5 telephone calls , and an in-home messaging device provided over 3 months to instruct patients in functionally based exercises and adaptive strategies . Usual care participants received routine rehabilitation care as prescribed by their physicians . The primary outcome measures were improvement in function at 6 months , measured by both the motor subscale of the Telephone Version of Functional Independence Measure and by the function scales of the Late-Life Function and Disability Instrument . Results — The 2 complementary primary outcomes ( Late-Life Function and Disability Instrument Function and Telephone Version of Functional Independence Measure ) improved at 6 months for the STeleR group and declined for the usual care group , but the differences were not statistically significant ( P=0.25 , Late-Life Function and Disability Instrument ; P=0.316 ) . Several of secondary outcomes were statistically significant . At 6 months , compared with the usual care group , the STeleR group showed statistically significant improvements in 4 of the 5 Late-Life Function and Disability Instrument disability component subscales ( P<0.05 ) , and approached significance in 1 of the 3 Function component subscales ( P=0.06 ) . Conclusions — The STeleR intervention significantly improved physical function , with improvements persisting up to 3 months after completing the intervention . STeleR could be a useful supplement to traditional poststroke rehabilitation given the limited re sources available for in-home rehabilitation for stroke survivors .
