cDifferent minimal clinically important difference values for grasp strength reflect arm dominance versus arm affected. A 0° angle value indicates full extension to a straight arm (for elbow) and a straight hand for finger metacarpophalangeal joints.

dMinimal clinically important difference for that measure.

eN/A: not applicable.

fMCP: metacarpophalangeal joint
