Introduction:
Successful recovery of upper limb motor function in poststroke adult patients occurs only in 20% of cases. Motor training in virtual environment allows to create the necessary training space for motor skills relearning, as well as provide interactive biofeedback and intensify rehabilitation process.
Objectives:
Reveal the efficacy of non-immersive, markerless virtual reality system as a rehabilitation tool for upper limb in poststroke patients.
Materials and methods:
17 patients met the inclusion criteria (10 males; 7 females) at the age of 30 to 60 years and 3 to 12 months after stroke were included. Main group (n=10), received two weeks (30 min, 6 days\week) of virtual biofeedback training on Kinect based system «Habilect». Control group (n=7) received equal time conventional therapy. Evaluation methods: Fugl-Meyer Assessment scale (FM), Action Research Arm Test (ARAT), 3D motion capture system.
Results:
Main group patients showed improvements (p<0,05) in FM: arm and hand movements, and total score; ARAT: significant (p<0,05) improvement of pinch grip, gross movements and total score. Motion analysis showed significant increase in reaching movement speed and changes in the reaching synergy. The shoulder flexion torque decreased by 23% (p<0,05) with correlated elbow extension torque decreasing by 11% (p<0,05). Shoulder abduction torque decreased by 31% (p<0,05) and was correlated with shoulder flexion. In control group were found improvements (p<0,05) only in range of passive movements (FM).
Conclusion:
Virtual biofeedback training is effective method for stroke rehabilitation that promotes arm function increasing, improves movement coordination and proved to be useful addition to the traditional methods of rehabilitation.
