[Effectiveness of rehabilitation with virtual reality and biofeedback in recovery of hand function after stroke]

To evaluate the effectiveness and safety of the rehabilitation glove (RG) with virtual reality (VR) and biofeedback (BFB) on recovery of the hand function in patients during the late recovery period after first hemispheric ischemic stroke (IS).

The study was randomized and controlled. One hundred and six patients (age 58.8±4.3 years, time after stroke onset - 8.7±2.1 months) were included in the final analysis. The intervention group (n=56) received rehabilitation with RG and VR. The control group (n=50) received individualized physical therapy. The primary end points were a change in the Fugl-Meyer scale score (FMA-UE), in the Action Research Arm Test (ARAT), and in the nine holes peg test (NHPT). Secondary end points included changes in MRCS, MAS, MoCA, HADS, modified Barthel index (MBI) and quality of life (EQ-5D-5L).

Improvement of the motor function in the intervention group on FMA-UE scale (an increase of ≥7 points in sections A-D) was observed in 46.4% of patients, on ARAT (an increase of ≥5 points) in 53.6% of patients. There was a significant decrease in time from 36.8±6.3 sec. to 22.0±3.9 sec. on NHPT. A negative correlation was observed between the average ARAT score and anxiety (r=-0.7; p<0.05) and depression (r=-0.67; p<0.05). There was also a significant increase in EQ-5D-5L (VAS) by the end of rehabilitation in both groups with better scores in the intervention group (p=0.03).

Rehabilitation based on VR, RG, and BFB is effective in the rehabilitation of dexterous hand function in patients with first hemispheric IS.
