About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • men and women with age equal or higher than 18 years old;
  • having clinical diagnosis of neurological pathology;
  • presenting fine motor coordination deficit and in grip strength;
  • being able to understand instructions in order to perform the tasks of the virtual environment;
  • minimum score of 23/24 (from a total of 30) in the Mini-Mental State Examination (MMSE)

Exclusion criteria

  • Not accepting to participate in this research

Treatment and study plan

Jamar

Diagnostic Test

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.

Wooden box

Diagnostic Test

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.

Virtual environment

Other

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.

Primary outcomes

  1. Virtual environment

    Time frame: 120 minutes

    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.

Secondary outcomes

  1. Wooden box

    Time frame: Immediately after at the Session 1, 4 and 8.

    The motor coordination evaluation was made in the first, fourth and eighth sessions. Each volunteer used three balls, or spheres, of different sizes (small, medium, large). The objective was to insert each ball in each orifice. The time was measured with a chronometer.

  2. Dynamometer JAMAR

    Time frame: Immediately after at the Session 1, 4 and 8.

    The grip strength (kgf) was evaluated in the first, fourth and eighth sessions.
