Forearm rotation affects grip strength. In a study with 40 volunteers, an overall decrease in grip strength was observed when the forearm rotated from pronation to supination. In males grip strength in pronation was significantly lower compared to the neutral and supinated position, with the wrist free as well as in an immobilized wrist position. In females this was only observed with a free wrist position, but with the wrist immobilized, the grip strength was higher in supination compared to neutral and pronation.
