Background: Occupation-based interventions are effective in hand rehabilitation. The purpose of this study was to identify the grasp and pinch patterns used during specific ceramic activities for rehabilitative interventions.
Method: A convenience sample of 59 videos with 38 subjects were taken of adults without hand dysfunction completing various ceramic activities. Elementary Grasp Actions (EGA’s) were analyzed to identify the different grasps and pinch patterns.
Results: The EGA’s occurred 279 times across 12 ceramics activities. The EGA’s with the highest frequencies include nonprehensile, pinch, and lateral pinch. Nonprehensile was the most frequently used grasp used by the left hand. The EGA’s with the most prolonged durations were nonprehensile, special pinch, and oblique. The mean frequency and duration of each grasp and pinch pattern for specific ceramic activities are presented.
Conclusion: Therapists can use the results of this study to help individuals with hand dysfunction through specific ceramic activity interventions.
