An Australian and Canadian research team examined the concurrent validity of adherence to home strengthening exercises measured by exercise diaries and a self-rated scale, compared to adherence measured using an accelerometer concealed in an ankle cuff weight. Test-retest reliability of the self-rated scale was also assessed. They found that exercise adherence was significantly overestimated in diaries and was moderately correlated with accelerometer data.
