- Brief Summary
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.

Group Intervention Description Blood Flow Restriction Training，BFRT Exercise Intervention Blood Flow Restriction Training (BFRT) is a special training technique aimed at limiting blood flow by using cuffs or elastic bands on the limbs to promote muscle growth and improve strength. BFRT was originally designed for rehabilitation injured athletes as it can improve muscle strength while reducing load, helping to avoid further injuries during the rehabilitation process. But as research deepens, it is gradually being applied to a wider range of fitness and training fields. One major advantage of BFRT is that it allows for efficient training under relatively light loads, reducing the burden on joints and tendons, making it suitable for people who find it difficult to withstand high-intensity training due to injuries or other reasons. Meanwhile, BFRT also has the characteristic of achieving muscle growth and strength growth in a short period of time, and it is considered a time-saving training method. BFRT can not only be used for strength training, but also for rehabilitation, i Instrument-Assisted Soft Tissue Mobilization，IASTM Instrument-Assisted Soft Tissue Mobilization Instrument Assisted Soft Tissue Mobilization (IASTM) is a physical therapy technique that utilizes specially designed tools (such as metal or plastic scraping boards) to assist in the treatment of soft tissue problems. Mainly used in rehabilitation medicine, sports medicine, and plastic surgery, it is used to handle tension, adhesion, pain, and motor dysfunction of muscles, fascia, and tendons. The edge design of IASTM special tools can loosen adhesions in tissues, improving their elasticity and plasticity. Regulating pathological areas through neural pathways, reducing pain and improving neurological function. And different types of treatment tools improve the accuracy of treatment, promote blood circulation, accelerate the rehabilitation process, improve tissue elasticity, expand joint range of motion, and have lower risks and complications compared to invasive surgery. Tuinal Tuinal Tuinal is an important physical therapy method in traditional Chinese medicine, which can be traced back to the Shang Dynasty around 2700 BC. With the continuous development of social economy and cultural exchange, Tuinal technology based on traditional Chinese medicine ethics and guided by modern scientific theories gradually emerged. The technical treatment methods are mainly relaxation techniques, supplemented by movement techniques. Following the principle of combining movement and stillness, emphasizing both muscles and bones, and progressing step by step, massage has significant therapeutic effects on skeletal muscle diseases. In clinical practice, massage therapists use various techniques to apply to specific parts or acupoints of the human body, keeping the nerves and muscle tissues in a good state, improving the unblocking of meridians, relaxing soft tissues, restoring flexibility, and relieving symptoms such as muscle spasms and pain.
- Primary Outcome Measures
Name Time Method Foot and Ankle Ability Measure（FAAM） 4-6week Foot and Ankle Ability Measure (FAAM) is a scale used to evaluate ankle joint function, which includes questions about pain, function, and quality of life, and can be used to assess the overall condition of patients with ankle instability. The functional score includes two types of assessments: the functional level of daily life (FAAM-ADL) and the functional level of physical activity (FAAM-SPORT). The score range is usually from 0 to 100, where 100 represents completely normal ankle joint function, and 0 represents extreme restriction or complete inability to use the ankle joint.
Cumberland Ankle Instability Tool，CAIT 4-6week Evaluated the patient's perception of ankle instability, including the frequency, CAIT typically includes a specific range of questions, each of which may have different scores. The total score is usually between 0 and 30 points, with higher scores indicating higher stability intensity, and impact of symptoms
Ankle joint strength test 4-6week The experimental strength data was tested using a handheld digital muscle strength tester (model: FM-204M series muscle strength tester). The measurement unit of this muscle strength tester is N, with a measurement unit range of ± 50kgf and a measurement accuracy of ± 0.5% FS (range) ± 1 digital peak. The measured data includes both peak strength and instantaneous strength values. Therefore, this study used a handheld digital muscle strength tester, where participants sat in a suitable position, fixed the bottom of the instrument on the ground, and then applied force in different directions through their ankles. Measure the maximum force in the direction of dorsiflexion and plantarflexion of the ankle joint, abduction and eversion of the foot, and adduction and eversion. The strength test for each different exercise segment needs to be completed three times, and the average of the maximum strength values from the three tests is taken.
Ankle joint range of motion 4-6week This study used a high-precision joint motion angle measuring ruler to measure the range of motion of different ankle functions in both sitting and supine positions, including measurements of dorsiflexion and plantar flexion of the ankle, as well as measurements of varus and eversion of the foot. The larger the angle, the better the improvement in joint motion.
