The multiple acupuncture techniques have been used to relieve the pain of lateral ankle sprain. Recently, early functional rehabilitation is emphasized in rehabilitative concepts using active ROM, facilitated proprioception, alphabet exercise and so forth. Similarly, in oriental rehabilition medicine, traditional movement technique called "Dong-Ki" has been used to relieve pain of ankle sprain. So we used "Dong-Ki" technique with SSP(silver spike point) electrotherapy transformed from alphabet exercise and evaluated the effects in method of randomized controlled trials. Methods : 27 outpatients with lateral ankle sprains were randomized into two groups : 15 samples and 12 controls. Sample group was treated with "Dong-Ki" technique(writing his name with foot) with SSP electrotherapy to relieve pain during additionally. "Dong-KI". Outcomes were measured by 10cm VAS and ankle circumference(cm). Results : In terms of VAS, Sample group had inclination of pain relieving but not significantly meaningful. In terms of ankle circumference measurement, Sample group showed significantly improved.

Purpose: The aim of the present study was to investigate the effects of proprioceptive neuromuscular facilitation (PNF) and taping interventions on balance ability, joint position sense, and ankle joint strength. Methods: Thirty subjects who had experienced an ankle sprain within the previous 3 months participated in this study. The subjects were randomly assigned to a PNF group (n=15) or a taping group (n=15). Before and after the interventions, ankle dorsi-flexion and plantar-flexion strength, joint position error, and total center of pressure movements in one leg while in a standing position were measured. Results: Regardless of the group allocation, ankle dorsi-flexion and plantar-flexion strength significantly improved after the interventions (p<0.05). Compared to preintervention measurements, joint position errors were significantly reduced postintervention (p<0.05). The PNF intervention significantly decreased the total lateral movement of the center of pressure in the one leg standing condition (p<0.05). Conclusion: Both PNF and taping interventions improved joint position sense and ankle joint strength. In common with the findings of a previous study, the PNF intervention improved balance ability. Further study is required to investigate the effects of various PNF and taping interventions on ankle performance in subjects with chronic ankle sprains.

Chronic lateral ankle instability is a major complication of acute ankle sprains, which can cause discomfort in both daily and sports activity. In addition, it may result in degenerative changes to the ankle joint in the long term. An accurate diagnostic approach and successful treatment plan can be established based on a comprehensive understanding of the concept of functional and mechanical instability. The patients' history and correct physical examination would be the first and most important step. The hindfoot alignment, competence of the lateral ligaments, and proprioceptive function should be evaluated. Additional information can be gathered using standard and stress radiographs. In addition, concomitant pathologic conditions can be investigated by magnetic resonance imaging. Conservative rehabilitation composed of the range of motion, muscle strengthening, and proprioceptive exercise is the main treatment for functional instability and mechanical instability. Regarding the mechanical instability, surgical treatment can be considered for irresponsible patients after a sufficient period of rehabilitation. Anatomic repair (modified $Brostr{\ddot{o}}m$ operation) is regarded as the gold standard procedure. In cases with poor prognostic factors, an anatomical reconstruction or additional procedures can be chosen. For combined intra-articular pathologies, arthroscopic procedures should be conducted, and arthroscopic lateral ligament repair has recently been introduced. Regarding the postoperative management, early functional rehabilitation with short term immobilization is recommended.

Purpose: Recently, many studies on robotic rehabilitation have been conducted, but such studies on patients with ankle sprains are lacking. This study aimed to investigate the effects of robot-assisted rehabilitation on the range of motion of the ankle and balance in patients with ankle sprain. METHODS: This study used the A-B-A' design and was conducted for a total of fifteen days. The subjects performed general physical therapy for five days each, during the baseline A and A' periods. In period B, robot rehabilitation was performed for five days, along with general physical therapy. The subjects were evaluated based on weight-bearing lunge test (WBLT), single leg stance (SLS), and functional reach test (FRT). RESULTS: The WBLT, STS, and FRT showed significant improvement in periods B and A' compared to period A, but there was no significant improvement in period A' compared to period B. Conclusion: This study confirmed that robot-assisted rehabilitation was an effective intervention for improving the function of patients with ankle sprain. In the future, a study with a control group comparison should be performed.

This study aimed to evaluate clinical practice guidelines (CPGs) for ankle sprains using the Appraisal of Guidelines for Research and Evaluation II tool, using electronic databases (GIN, PubMed, EMBASE, NCKM, CNKI, CiNii, WanFang database, RISS, and SCOPUS), to suggest strategies for improvement in the future. The search was performed on April 23, 2021 and 10 CPGs were selected for evaluation. Three CPGs were recommended without modification (Class A scores), five were recommended with modification (Class B), and two were not recommended (Class C scores). The CPG domain that received the lowest score was "applicability." The traditional medicine CPGs scored higher [Class A (n = 1) and Class B (n = 1)] than the conventional Western medicine CPGs [Class A (n = 2), Class B (n = 4), and Class C (n = 2)] and were considered to be more methodical. In the future, more research into traditional medicine is required.

Background : Ankle inversion sprains are one of the most common injuries in sports and activities of daily living that mostly concern physically active individuals. In most researches, proprioceptive deficit, muscle weakness and/or absent coordination have been regarded as a contributing factors. Despite the high incidence of ankle sprain and instability, therapeutic approaches to properly manage the symptoms have rarely been investigated. This study aimed to identify the effect of proprioceptive exercise program that is easy to integrate in normal training program. Methods : Subjects were randomly allocated to control group and experimental group consisting of 11 and 10 patients, respectively. The conservative treatment for the control group consisted of hot packs, ultrasound and TENS. In addition, the experimental group performed 7 exercises to enhance proprioceptive function of ankle joint. The therapeutic intervention of the controland experimental groups was performed a total of 20 exercise sessions, averaging 50 hour each, 5 times per week for 4 weeks. To compare the two groups, the level of ankle disability was assessed by using the ankle injury score scale in pre- and post-treatment. Results : On assessment of post-treatment, there were statistically significant differences in the scores of all sub-items, except for ankle laxity and range of motion, and the total score of ankle injury score scale between the two groups(p<0.05). In comparison between pre- and post-treatments, the significant difference in the scores of all sub-items and total score didn't appear for the control group, while the scores of most sub-items and total score of the experimental group were shown the statistically significant difference(p<0.05). Conclusion : The findings suggest that the proprioceptive exercise program is more effective for relieving ankle disability than conservative treatment therefore, the program to improve proprioceptive function should be recommended for prevention and rehabilitation of recurrent ankle inversion injuries.

The purpose of this study was to measure magnitude of lower leg muscle activity during dynamic stability tests performed on an unstable board by subjects with sprained lateral ankles. Fifteen lateral ankle sprain subjects(8 male, 7 female) participated in this study. The muscle activity was measured at gastrocnemious, tibialis anterior, peroneus longus during dynamic stability tests performed on Biodex stability system as surface EMG. The EMG amplitude of each muscle was normalized to the amplitude in the maximal voluntary isometric contraction(MVIC) of each muscle. As results, peroneus longus evidenced significant difference at stable and unstable grade comparing injured with uninjured sides. Gastrocnemious and tibialis anterior evidenced no significant difference. Change of muscle activity with stable and unstable grade evidenced no significant difference on injured and uninjured sides. The data provided information on peroneus longus contributes to dynamic stability after lateral ankle sprains. Peroneus longus training program may have to be emphasized after an ankle sprain.

Objective: Epidemiological research shows that 47 to 73% of athletes suffer from recurrent ankle sprains. Joint mobilization techniques (JMT) implemented in correcting may be beneficial in the management of ankle injuries. The purpose of this study is to examine the immediate JM on ankle complex as clinical measures in individuals with chronic ankle instability (CAI) through intervention. Method: Thirteen subjects with CAI (8 males and 5 females) participated in this study. Each subject tried total four alignments (Navicular drop test: NDT, Standing rearfoot angle: SRA, Tibia torsion: TT, and dorsiflexion range of motion: DFROM). The participants were performed the 10 meter shuttle run after JMT for post-task. Finally, it was tried to compare between pre-post tasks after shuttle run. Results: SRA and DFROM after intervention showed significant differences. SRA (p=.026), and DFROM (p=.034). Conclusion: We concluded that the JMT has resulted in improvement in SRA, DFROM. Increased DFROM and varus shapes of foot would be closed kinetic chain, indicating that reduce the risk factors of ankle sprain. Future study needs to be conducted in order to measure the effects of prolonged intervention of JMT.

Purpose: Anterior drawer and varus stress radiographs are commonly to diagnose chronic lateral ankle instability. We compared the preoperative stress radiographs with the intraoperative radiographs under anesthesia to determine the accuracy and efficacy of stress radiographs in an outpatient clinical environment. Materials and Methods: Data was collected from patients who underwent a modified $Brostr{\ddot{o}}m$ operation for painful chronic unilateral lateral ankle instability between January 2014 and June 2016. Subjects were divided into three groups-complete tear, partial tear, and instability without rupture-according to the status of preoperative MRI findings of the anterior talofibular ligament. The anterior drawer and varus stress radiographs were taken preoperatively and intraoperatively under anesthesia. Results: Ninety-six patients, with a mean age of 29.63 years, were enrolled. There were 39, 46, and 11 patients in the complete tear, partial tear, and instability without rupture groups, respectively. On the anterior drawer and varus stress radiographs of the affected limb, talar anterior translation and varus tilting were significantly increased by 2.56 mm and $2.0^{\circ}$. The gaps between the unaffected limbs were also increased by 2.47 mm and $1.32^{\circ}$ after anesthesia. Although the stress radiographs were taken under anesthesia, the results were often smaller than the diagnostic value. Conclusion: Stress radiographs for painful chronic lateral ankle instability taken at the outpatient clinic might be inaccurate for diagnosis.
