Home-based prescribed exercise improves balance-related activities and gait speed in people with Parkinson 's disease , and these improvements are similar to improvements with equivalent centre-based exercise .
QUESTIONS In people with Parkinson 's disease , does home-based prescribed exercise improve balance-related activities and quality of life compared with no intervention ?
Are the effects of home-based exercise similar to those of equivalent centre-based exercise ?
Minimal Detectable Change of the Timed “Up & Go” Test and the Dynamic Gait Index in People With Parkinson Disease
Background The minimal detectable change ( MDC ) is the smallest amount of difference in individual scores that represents true change ( beyond r and om measurement error ) . The MDCs of the Timed “ Up & Go ” Test ( TUG ) and the Dynamic Gait Index ( DGI ) in people with Parkinson disease ( PD ) are largely unknown , limiting the interpretability of the change scores of both measures . Objective The purpose of this study was to estimate the MDCs of the TUG and the DGI in people with PD . Design This investigation was a prospect i ve cohort study . Methods Seventy-two participants were recruited from special clinics for movement disorders at a university hospital . Their mean age was 67.5 years , and 61 % were men . All participants completed the TUG and the DGI assessment s twice , about 14 days apart . The MDC was calculated from the st and ard error of measurement . The percentage MDC ( MDC% ) was calculated as the MDC divided by the mean of all scores for the sample . Furthermore , the intraclass correlation coefficient was used to examine the reproducibility between testing sessions ( test-retest reliability ) . Results The respective MDC and MDC% of the TUG were 3.5 seconds and 29.8 , and those of the DGI were 2.9 points and 13.3 . The test-retest reliability values for the TUG and the DGI were high ; the intraclass correlation coefficients were .80 and .84 , respectively . Limitations The study sample was a convenience sample , and the participants had mild to moderately severe PD . Conclusions The results showed that the TUG and the DGI have generally acceptable r and om measurement error and test-retest reliability . These findings should help clinicians and research ers determine whether a change in an individual patient with PD is a true change
