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

Study on the Effect of Blood Flow Restriction Training Combined With IASTAM on Symptoms in Patients With Chronic Ankle Instability

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.

Inclusion Criteria:

• Age: 18-35 years old
• Course of illness: Suffering from chronic ankle instability symptoms that last for at least 3 months
• Symptoms: Ankle instability, frequent ankle sprains, discomfort during walking or exercise

• Structural examination: No joint structural lesions or congenital ankle deformities,
• Medical history: Have not undergone ankle surgery or have external injuries
• Health status: No serious heart, lung, nervous system or other systemic diseases
• Exercise level: Able to complete the exercise intervention and evaluation tasks specified in the experiment
• Agree to participate in the study: Has limited exercise ability and is unable to complete the research task

Exclusion Criteria:

• Under 18 years old or over 35 years old
• Acute ankle injury or no joint injury
• No ankle instability or unwillingness to cooperate with research requirements
• Failed ankle function screening
• Structural lesions or congenital ankle deformities present in the ankle joint
• Have undergone ankle surgery or have obvious injuries or wounds
