Study on the Effect of Exercise Intervention Combined With Physical Therapy on Chronic Ankle Instability Symptoms

Purpose; Through experimental observation of exercise intervention (blood flow restriction training combined with low load ankle muscle strength training and balance training) combined with instrument tool therapy (Instrument Soft Tissue Release Technique, IASTM), the intervention effect on ankle function, strength, and joint range of motion of sports dance athletes with ankle instability was observed. Method; 45 subjects with unstable, restricted or uncomfortable ankle joints were selected as observation subjects and randomly divided into ankle blood flow restriction training combined with IASTM group (n=15), ankle blood flow restriction training alone (n=15), and traditional ankle strength training (n=15). The intervention lasted for 6 weeks, once a week. Cumberland ankle instability assessment, FAAM ankle function assessment score, and ankle range of motion measurement were performed at three time points before intervention, after the first intervention, and after 6 weeks of intervention for three groups. The ankle strength test was only compared and analyzed at two time points before and after intervention.
