A Streamlined 4-item Wolf Motor Function Test for Efficient Assessment of Upper Extremity Motor Function in Chronic Stroke Survivors.

The study only included patients with mild-to-moderate impairment in the subacute and chronic phases, so it may not work for severe or acute cases. The 4-item version excludes tasks involving fine motor control, precision pinch, and bilateral coordination, meaning it cannot fully assess hand dexterity. The minimal clinically important difference was derived using the Fugl-Meyer Assessment, which measures impairment rather than daily activity, so the threshold might not perfectly reflect functional changes.

Do not use the WMFT-4 as a standalone measure for fine motor skills or hand dexterity. It omits critical tasks like precision pinch and bilateral coordination, so it should be paired with other assessments if you need a comprehensive profile of upper extremity function.
