Use half-cut wood training method for rehabilitation of Chinese patients with knee instability

Previous studies have shown that if a series of overlapping segments were connected via pin joints, these interlocking joints would create a system that would allow the movement of one joint to affect the movement of another joint within the kinetic chain. This leads to knees and ankles operating in unity. In order to stabilize knees, ankle mobility should therefore be improved. Our study therefore developed Half-wood Training method to reflect these principles. In this method, endways quincuncial piles were cut into half and placed transversely, in order to decrease the risk and the degree of difficulty, allowing for comfortable and convenient barefooted practice for patients with knee instability. There are four phases of the intervention consisting of four phases with 40 lessons in total and the intervention will take both supervised individual level training plus self-directed exercise and qualified physicians will deliver the intervention program. Each lesson takes 45 minutes: (1). Phase 1: 10 lessons in Education and posture training. This include basic understanding of the function of joints, characteristics of normal and abnormal postures and movements and joint related exercise. This phase will last for 5 days, with 90 minutes supervised training, and 60 minutes self-directed exercise per day. The self-directed exercise is to review and repeat the exercise actions during the supervised training session (2). 10 lessons in Phase 2. This phase will focus on multiple joints' training and respiratory training. The purpose of the exercise is to facilitate coordination of action and respiration by exercise starting from one joint exercise to multiple joint based exercise. This will take 5 days with 90 minutes supervised exercise and 1 hours 30 minutes self-directed exercise time per day. The self-directed exercise is to review and repeat the exercise actions during the supervised training session (3). 10 lessons in Phase 3. This phase will focus on abnormal knee joint and spine training. This phase exercise is to correct abnormal posture and shape of the spine. This willl take 5 days with 90 minutes supervised exercise and 1hours 30 minutes self-directed exercise time per day.The self-directed exercise is to review and repeat the exercise actions during the supervised training session (4). 10 lessons in phase 4. This phase will focus on application in daily life. This will include rolling and balance training to enhance physical flexibility. This phase will take 6 days with 90 minutes supervised exercise and 1hours 30 minutes self-directed exercise time per day using. The self-directed exercise is to review and repeat the exercise actions during the supervised training session Undertaking a supervised series of exercises on the Half-cut woods barefooted improves ankle flexion, and simultaneously strengthens the ankle and back of the calf muscles, quadriceps strength, knee and ankle range of motion, lower extremity muscle flexibility. Half-cut Wood Training is designed for this study at Tonwo Clinic in China. Half-cut Wood Training materials consist of logs that are cut into halves and placed transversely across the floor (length=40cm-50cm, width=15cm-25cm, height=10cm-20cm). An intervention guideline is designed for this study. The intervention will consist of 3 hours exercise session per day (which is equivalent 2 lessons per day) over 3 months period of time depending on individual's improvement level. The intervention is individual level based.
