Fu's Subcutaneous Needling for Postacute Lateral Ankle Sprain and Prevention of Chronic Ankle Instability
Sponsor: Guangzhou University of Chinese Medicine
Summary
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.

Interventions
Fu's Subcutaneous Needling therapy
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.
Ankle joint aids combined with exercise therapy
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. To ensure standardization, a unified specification is selected for the ankle joint orthosis: Product number: 100159548, the 195R Super Sports Ankle Brace for Inversion/Eversion Sprains and Ligament Fixation by McDavid from the United States. During the treatment with ankle joint orthosis, complete the resistance training every day.
