Abstract

Is there a correlation between thumb mobility and mechanical hand function? The metacarpophalangeal mobility, the web, grip force and dexterity were measured on volunteers. Statistical analysis showed a good correlation between the dominant and nondominant hand. Thumb mobility shows no correlation with grip force and dexterity while the width of the webspace has a clear influence on them. We could not find a compensatory mechanism between thumb mobility and the first web.
