简要总结
Knee osteoarthritis (KOA) is one of the leading causes of lower limb disability among the elderly and can cause loss of knee joint proprioception that contributes towards deterioration of postural balance. Maintaining a good postural stability is essential while performing everyday functional activities and to avoid falls. Exercise training has been reported to reduce pain as well as improve performance of functional tasks in patients with KOA however compliance to exercise can be challenging due to pain, lack of motivation and traditional nature of exercise that can easily overtax patients. Furthermore, there are not exercise programs that are specifically designed for patients with KOA in order to address lost knee joint proprioception. Recent studies have also demonstrated that visual feedback during exercise can enhance the benefits of exercise training. Therefore, the aim of the proposed study is to implement an interactive sensor-based exercise training to improve postural balance, gait and activities of daily living in patients with KOA.
详细描述
The exercise intervention procedure is based on wearable sensor game-based balance-training program (Exergame). Subjects will perform progressive balance exercises such as ankle reaching or weight shifting, obstacle crossing, and ankle trail making task (i.e. motor-cognitive task). Real-time visual/audio lower-extremity joint motion feedback will be provided using wearable sensors (LEGSys, Biosensics LLC, Cambridge, MA, USA) to assist and encourage subjects to accurately execute each exercise task. The same wearable sensor technology is also used to quantify changes in balance and gait. Changes in balance, gait, fear of falling, physical activity, pain, and quality of life parameters will be assessed at the beginning and conclusion of the training program. Subjects will perform sensor-based interactive balance training (on computer screen), 2 x week, for a period of 6 weeks. The training consists of three balance tasks shown on a computer screen (1. ankle reaching task or weight shifting , 2. obstacle negotiation task, and 3. ankle trail making task (i.e. motor-cognitive task) intended to improve postural stability.
