Limitation of range of motion (ROM) changes grasping style. Therefore, we proposed a method to clarify the features of grasping styles of ROM-limited hands. First, we proposed to artificially limit ROM of healthy hands by using rigid strapping tape. The palmar adduction of the thumb's carpometacarpal (CM) joint and the extension of the thumb's metacarpal (MP) joint were the target of limitation. Then, we conducted an experiment to clarify the features of grasping styles of a ROM-limited hand. For the ROM-limited hand, several grasping styles were found in trials, and there was a tendency that one grasping style was chosen finally. Grasping styles finally selected by the ROM-limited hand tend to use side region of the thumb. CM joint and MP joint of the grasping styles finally selected by the ROM-limited hand tend to be farther from ROM boundary than those temporary appeared in the trial process.
