Rehabilitation Efficacy of Low-Load Blood Flow Restriction Training for Lateral Patellar Compression Syndrome

Each training session consists of a 10-minute warm-up (including power cycling, full-body stretching, etc.) At the same time, use the foam axis to relax the lateral oblique femoris and iliotibial band to relieve the pressure on the lateral side of the patella), 40 minutes of formal training (including wall squats with a ball, straight leg raising resistance training, terminal resistance knee extension training, bench kick ball clamping training, and balance training), and 10 minutes of relaxation (using a foam roller, foam axis and other combined techniques to relax the muscles Especially for the lower limb muscles such as the lateral femoris, iliotibial band, and tibialis anterior muscle.

The experimental group (LL-BFRT group) wore a flow-limiting pressure band for exercise during routine rehabilitation training. The blood flow limiting pressure band used in this study mainly consists of a 109\*10cm leg pressure band, a barometric display dial with a pressure range of 0-300mmHg, and a pressure pump. In the experiment, we fixed the blood flow restriction pressure band in the area for measuring the circumference and adjusted the blood flow restriction pressure according to the thigh circumference of the subjects to maintain it within the range of 40%-60% arterial occlusion pressure. The way to limit blood flow is intermittent inflation, that is, during the intervals of muscle strength training, the cuff deflation operation is carried out simultaneously.
