Brief Summary

We aimed to investigate the effects of virtual reality based rehabilitation program on patients with knee osteoarthritis.

Detailed Description

Sixty volunteer participants with knee osteoarthritis aged 40 to 65 years who were at stage of 2-3 according to the Kellgren Lawrence radiological evaluation were included in the study.

Participants were randomly divided into two groups as virtual and control group. While a conventional physiotherapy program consisting of electrotherapy and exercise program was applied to both groups 5 days a week for 6 weeks, a virtual reality program was added to the virtual group for 6 weeks, 5 days a week. At the beginning of the treatment and at the end of the sixth week, ROM, pain, kinesiophobia, proprioception, balance, muscle strength and functional status were evaluated between groups.

Study Groups

Virtual group

This virtual realtiy was implemented with MarVAJED® (Marmara Visual Auditory Joint Education Device) system which was developed by Marmara University, Department of Physiotherapy and Rehabilitation, Istanbul,Turkey. MarVAJED® is a system that evaulates the range of motion of the joints, analyzes the sensation of joint position, provides biofeedback support to increase joint control and the same time allows exercises to be controlled. This device analyzes the joint motion with the help of small sensors (Figure 2). The obtained data transfers to your mobile phone, to the tablet or to your personal computer. It stores the data by downloading it to the central server via internet for storage.

Group Type: EXPERIMENTAL

Virtual Reality based Rehabilitation Program

Intervention Type: OTHER

Virtual reality-based rehabilitation was implemented via MarVAJED system. At first the sensors of MarVAJED® were placed under and above the knee joint and then it was calibrated. The content of the game programs included in the MarVAJED system and how to perform these games with the exercises were explained to the participants. We used games called "Crazy Wings and Blasting Ball" included in the MarVAJED®.There was a bird figure in Crazy Wings game and represented knee joint of participants. Although the bird figure moved upwards during knee flexion, it moved downward in knee extension, there were some obstacles on the way of the bird went. The subjects were asked to follow the bird figure visually and to pass through the obstacles by flexing or extending their knees when they encountered obstacles.

Control group

Conventional physiotherapy consists of electrotherapy and exercise programs. Hotpack or coldpack, therapeutic ultrasound (US) and conventional TENS were applied as electrotherapy program.
