About

This study is to test the system composed by a 3D virtual environment, attached to the Leap Motion, evaluating its effects on the rehabilitation of hand movements in patients with motor alteration.

Full description

In order to elaborate the virtual environment, softwares for 3D content creation were used. The virtual environment is formed by four phases, each one having three spheres that are supposed to be inserted, one by one, into a hole located on the scenario floor. Each phase presents a level of difficulty, from pushing the object to performing the grip movement. By the end of each phase, a log file is generated with the time spent on it.

Enrollment: 10 patients

Sex: All

Ages: 18+ years old

Description:

For the tests, the volunteers used the access device (Leap Motion) and a computer that were previously installed. The intervention was composed by 8 sessions of 15 minutes each, where the volunteers used a virtual environment attached it to a Leap Motion, which is a sensor that allows to capture the movements that are produced by the hands and reproduce them in a computer through a 3D virtual environment in order to stimulate the execution of their finer movements. The strength (Jamar) and motor coordination (wooden box) evaluations were made in the first, fourth and eighth sessions with the objective of checking the gain progression or not of motion coordination and grip strength.

Treatment:

Diagnostic Test: Jamar

Diagnostic Test: Wooden box

Other: Virtual environment
