Abstract
This retrospective study examined the adequacy of manual muscle testing (MMT) as a measure of knee extension force among home-care patients. The knee extension strength of 31 patients was measured by MMT, hand-held dynamometry (HHD), and the five-repetition sit-to-stand-test (FRSTST). Although most patients were identified as weak by MMT, neither the sensitivity nor the specificity of MMT relative to HHD or FRSTST justifies its use as a sole measure of muscle strength among home care patients.
