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

Completed

• Conditions: Lateral Patellar Compression Syndrome

• Registration Number: NCT06988917
• Lead Sponsor: Peking University Third Hospital

Brief Summary

The purpose of this study is to understand the effect of low-load blood flow restriction training on the rehabilitation effect of patients after lateral patellar compression syndrome surgery, and to observe the differences between low-load blood flow restriction training combined with conventional rehabilitation training and conventional rehabilitation training. The main question it aims to answer is:

Can low-load blood flow restriction training improve the rehabilitation effect of patients after surgery for lateral patellar hypertension syndrome? Researchers compared conventional rehabilitation training with conventional rehabilitation training combined with low-load blood-limiting training to explore the effect of blood-limiting training combined with conventional rehabilitation training on the lower extremity function of patients after lateral patellar compression syndrome surgery, providing experimental and theoretical basis for formulating rehabilitation training programs.
