Functional Range of Motion During GRASP: Impact of the Object Location.

摘要

In this study we determined the Functional Range of Motion (FROM) of arm and hand joints for various functional tasks and different locations of the objects to be grasped. The data for F-ROM were collected in six healthy volunteers who used seven selected objects typical for daily activities. Subjects grasped the objects from six different locations marked at the working desk. The recorded data comprised nine hand and arm joint angles measured by Penny & Gilles flexible goniometers and torziometers during the reach/grasp/ release tasks. The FROM was defined as a difference between the maximum and the minimum joint angle; it was calculated for each task and for each object locations.
