Assessment of thumb to index pulp to pulp pinch grip strengths

In this study of fifty men and women with normal hand function, the strength of thumb to index finger pulp to pulp pinch grip was assessed with the remaining fingers either flexed or extended. When the pinch grip was performed with the remaining fingers flexed the value was up to 92% higher than when the remaining fingers were extended. In future studies where thumb to index finger pinch grip is used as an objective test of function then the position of the remaining fingers must be defined to aid interpretation of the results.
