Grip Movement Training for Adults With Fine Motor Limitation

The grip strength was evaluated through a dynamometer JAMAR 5030-J, formed by two parallel steel bars, one stationary and a mobile one, which can be adjusted in five different positions. The volunteer was sitting with a neutrally rotated abducted shoulder, elbow flexed at 90°, the forearm in neutral position, and the wrist between 0° and 30° of extension, 0° to 15° of ulnar variance and it was requested that he or she made the grip movement. This test was performed three times with a one-minute-break between each one.

The motor coordination evaluation was made through the measurement of the time spent to perform the task of fitting. To do so, a wooden box was built. In its upper part, there is a circular orifice with 6 cm of diameter.

The system proposed is composed by a virtual environment and an access device. The Leap Motion was used as the access device, making it possible to capture the movements performed by the hands.
