Minimal Detectable Change in Muscle Strength Measurements Obtained Using a Hand-Held Dynamometer in Patients with Stroke

Itoh S, Tanikawa H, Kondo H, Ozeki S, Ito T, Fujimura K, Teranishi T. Minimal Detectable Change in Muscle Strength Measurements Obtained Using a Hand-Held Dynamometer in Patients with Stroke. Jpn J Compr Rehabil Sci 2025; 16: 9-18. Objective: ). Methods: Patients who presented with chronic stroke hemiplegia for > 180 days post-stroke onset were analyzed. Muscle strength in the paretic lower limb was assessed using an HHD, and gait speed was evaluated. Results: of each muscle strength measurement was established, thereby providing a criterion for detecting actual changes that exceed the measurement error. Conclusions: allows for a more accurate assessment of the intervention effects.
