| dc.description.abstract | Low back pain affects people of all age, it is a very common health problem worldwide, about 80% of people may have complained about it in their life, and it’s ineffective if we use same treatment to all patient. In addition, rehabilitation therapy takes a long period of time, patient may lacked for motivation or don’t have enough physiotherapists, patients are often unable to finish the entire course of treatment. With the progress in technology and electronic process, makes virtual reality a useful tool in rehabilitation field. Cheaper and more accurate wearable device can also be substitute for motion tracking system in measuring patient’s movement.
The system is based on virtual reality and combined wireless sensor which is aim to assist therapist and patient in doing three stages low back pain rehabilitation exercises. The three stages are as follows: Observe and correct patient’s posture which is wrong and will makes them get injury. Therapist adjust proper rehabilitation target for every individual in order to training muscle strength. And in the third stage, the system will set the goal of exercise time and frequency for training endurance.
Total of 40 low back pain participate recruited in this study, clinical assessment (include VAS for unpleasantness, VAS for pain and Oswestry Low Back Disability Questionnaire), task performance and user acceptance of technology questionnaires are used to investigate the effectiveness of the system.
Experimental result shows that participates using the system for rehabilitation tool have significant improve in clinical assessment compare with traditional therapy group. In task performance, the study group also have great improvement. Finally, the users also have a high degree of technology acceptance and willing to continue to use the system for rehabilitation
