简要总结
Introduction: Fu's Subcutaneous Needling (FSN) is a new type of acupuncture treatment method based on the subcutaneous tissue sweeping technique, and it has been proven to have a good therapeutic effect on ankle sprain. However, at present, the difference between its curative effect and the ankle joint orthosis and exercise therapy recommended by the Guidelines remains unclear. Therefore, this study aims to explore the improvement effects of FSN on pain relief, joint function improvement, and ankle balance ability by comparing with ankle orthosis combined with exercise therapy. Verify whether it is more helpful in preventing the progression of lateral ankle sprain (LAS) to chronic ankle instability (CAI) and provide evidence-based basis for clinical decision-making.
Methods and analysis: This study is a randomized, parallel - controlled, single - center prospective clinical study. This study will include 60 subjects with postacute lateral ankle sprain and divide them into the FSN group and the combined treatment group. There are 30 cases in each group. The FSN group will be treated with Fu's subcutaneous needling three times a week for a total of two weeks. The Combined treatment group will wear ankle orthotics from 9:00 to 20:00, and complete resistance exercise training every day for a total of two weeks.Patients will be followed up for 6 months after the treatment. The main efficacy index is the change value of the Visual Analog Scale (VAS) compared to the baseline after 2 weeks of treatment. The secondary indicators include active range of motion (ROM) of the ankle joint, Star Excursion Balance Test (SEBT), and the Foot and Ankle Ability Measure (FAAM) to prove the clinical efficacy.
Ethics and dissemination: This study strictly adheres to the ethical guidelines of the Declaration of Helsinki.This study has passed the review of the Ethics Committee of Guangdong Provincial Hospital of Chinese Medicine. Approval No.: YF 2025 - 158 - 01. All subjects will sign a written informed consent form. The research results will be publicly published in journals indexed by SCI.

入选标准
- •Patients with first-time lateral ankle sprains

- •The patient presents with swelling and tenderness in the anteroinferior aspect of the lateral malleolus and the anterolateral aspect of the medial malleolus, and has limited mobility during inversion and flexion-extension.
- •Auxiliary examinations: No fracture or dislocation was found in the patient during the examination, and no fracture was detected by X-ray examination.
- •The patient's sprain time is more than 3 weeks and within 6 months.
- •Those who have not received surgical treatment at other medical institutions before coming to our hospital for treatment, can complete the treatment and accept follow - up.
- •The patients' ages range from 18 to 60 years old.
- •The patient voluntarily and is capable of signing the Informed Consent Form.
排除标准
- •Those with complete rupture of fractures or soft tissues such as muscles, tendons, and ligaments
- •Patients with severe primary diseases such as heart, liver, kidney, hematopoietic system diseases and mental diseases
- •Patients with tumors or tuberculosis in the ankle joint
- •Patients with rheumatic and rheumatoid arthritis, or gout.
- •Patients with acute inflammatory reactions such as redness, swelling, heat and pain and signs of infection in the ankle joint, or those accompanied by severe osteoarthritis.

研究组 & 干预措施
FSN group
Participants first assume the supine position. After routine disinfection, the Fu's subcutaneous needle is inserted parallelly into the subcutaneous loose connective tissue around the pathologically taut muscles (such as the tibialis anterior, peroneus longus, gastrocnemius, soleus, peroneus brevis, and extensor digitorum longus, etc.). After the needle is fully inserted, fix the protruding part of the hose holder onto the card slot.To minimize the participants' perception of pain, the doctor uses the index finger and ring finger to perform a smooth, gentle, and fan-shaped swinging motion in an alternating front-to-back manner.The sector angle is approximately 60°. It makes a total of round - trips 45 times within 30 seconds. The rocking motion is accompanied by Reperfusion Approach: A set of procedures consists of 20 times of rocking followed by 10 seconds of reperfusion method. Each target lesioned tense muscle requires 2 - 3 sets of the above - mentioned procedures.
干预措施: Fu's Subcutaneous Needling therapy (Procedure)
combined treatment group
Participants in the combination therapy group wore ankle orthoses during their daily activities from 9:00 to 20:00 every day for a total of 2 weeks. During the treatment with ankle joint orthosis, complete the resistance training every day.
干预措施: Ankle joint aids combined with exercise therapy (Behavioral)
结局指标
主要结局
Visual Analog Scale (VAS)
时间窗: The evaluators measure the outcomes at the baseline, on day 7, day 14, and during the follow - up period (day 28, day 42, 3 months, and 6 months after the start of treatment).
The scoring range of the Visual Analogue Scale (VAS) is 0 - 100 mm, which is used for objectively quantifying the pain level. The participants were instructed to indicate the severity of their ankle pain by marking a point on a continuous horizontal line segment, with 0 mm representing the least pain and 100 mm representing the most severe pain.
次要结局
- active range of motion of the ankle joint(was measured at the baseline, on the 14th day, and during the follow - up period.)
- The Star Excursion Balance Test(at the baseline, on the 7th day, on the 14th day, and during the follow-up period.)
- The Foot and Ankle Ability Measure(at the baseline, on the 14th day, and during the follow - up period.)
- Cumberland Ankle Instability Tool(at the baseline, on the 14th day, and during the follow - up period.)
