The purpose of this study was to determine the relationship with the Y-Balance Test, which evaluates dynamic balance ability according to the ankle joint dorsiflexion range of motion in a non-weight bearing posture. This study involved 27 male soccer players who regularly participate in the K3 League with more than 10 years of soccer experience. The Pearson Rank Correlation Coefficient was used to verify the relationship between ankle joint dorsiflexion and dynamic balance ability. The results of this study showed significant differences in PLRD (P<.05) and CS (P<.01) in the HADR group. A significant correlation between ankle joint dorsi-flexion range of motion and severity was found only in PMRD, PLRD, and CS. Therefore, a decrease in ankle joint dorsi-flexion is associated with a decrease in balance ability. In order to prevent injuries in soccer players, it is believed that regular evaluation of ankle joint range of motion as well as training to improve knee and hip joint strength and proprioception are necessary.

Background: Increased foot pronation causes biomedchanical changes at the lower limbs, which may result in musculoskeletal injuries at the proximal joints. Pronation rear-foot leads to plantar fasciitis, Achilles tendonitis, and posterior tibial tendonitis pathologically. According to the recent meta-analysis, They showed that therapeutic adhesive taping is more effective than foot orthoses and motion control footwear, low-Dye (LD) taping has become the most popular method used by physiotherapists. Objects: The purpose of this study was to determine the immediate effects of LD taping results in different ankle motion and ground reaction force (GRF) as before and after applied LD taping on pronated rear-foot during gait. Methods: Twenty-four participants were recruited for this study. The gait data were recorded using an 8-camera motion capture system and two force platforms. At first, the experiments were carried out that participants walked barefoot without LD taping. And then they walked both feet was applied LD taping. Results: The ankle inversion minimum was significantly greater after LD taping than before LD taping (p=.04); however, in the GRF, there were no significant differences in the inversion maximum or total motion of the stance phase (p=.33, p=.07), or in the vertical (p=.33), posterior (p=.22), and lateral (p=.14) peak forces. Conclusion: The application of taping to pronation rear-foot assists in increased ankle inversion.

Purpose: We present clinical usefulness of saphenous neurocutaneous island flap for reconstruction of soft tissue defect of the lower leg, especially anteromedial aspect, including foot and ankle. Materials and Methods: Thirteen cases of soft tissue defects in the lower leg including foot and ankle which were 6 cases of pretibial area, 2 cases of anteromedial aspect of distal two third, 2 cases of ankle, and 3 cases of foot were treated saphenous neurocutaneous island flap. They were proximally based flap 3 cases and distally based flap 10 cases. Clinically the flaps ranged in size from $4{\times}5\;cm$ to $6{\times}12\;cm$. Results: All of the flaps except 1 case survived completely. Three cases, however, had marginal necrosis. One case of flap failure was proximal tibia fracture accompanied with injury of the flap pedicle which was difficult in flap elevation, subsequently. Conclusion: The saphenous neurocutaneous island flap is a simple, reliable procedure with a versatility for soft tissue coverage of the lower leg, especially anteomedial aspect, including foot and ankle. In case of another injuries accompanied near the saphenous nerve, careful attention should be made.

Purpose: A distal tibiofibular syndesmosis injury with an ankle fracture is usually fixed with syndesmotic screws. Knotless Tightrope$^{(R)}$ has been used as an alternative procedure because of the fewer reported complications. Therefore, this study compared the two surgeries. Materials and Methods: Forty-two patients, who underwent syndesmotic screw fixation, and 34 patients, who underwent Knotless Tightrope$^{(R)}$ fixation for distal tibiofibular syndesmosis injury from February 2014 to February 2016, were analyzed retrospectively. The visual analogue scale (VAS) score, American Orthopaedic Foot and Ankle Society (AOFAS) score, range of motion of ankle at 1 year after surgery, tibiofibular clear space, and tibiofibular interval at preoperative, postoperative and 1 year after surgery were investigated. Results: The VAS score, AOFAS score and radiographs were similar in the two groups. Knotless Tightrope$^{(R)}$ showed better results in complications and plantarflexion. Conclusion: Knotless Tightrope$^{(R)}$ fixation is a useful treatment that does not show a difference in fixation strength and clinical outcome. Knotless Tightrope$^{(R)}$ fixation also has an advantage in the range of motion and complications.

The purpose of this study was to analyze the effects of ankle flexibility, gender, and Q-angle on the ankle joint injury factors during one leg drop landing. For this study, 16 males(age: 20.19±1.78 years, mass: 69.54±10.12 kg, height: 173.22±4.43 cm) and 16 females(age: 21.05±1.53 years, mass: 61.75±6.97 kg, height: 159.34±4.56 cm) in their 20's majoring in physical education using the right foot as their dominant feet were selected as subjects. First, an independent t-test of joint motion and joint moment according to the experience of ankle injury was conducted to determine the effect of physical characteristics on ankle joint injury during one leg drop landing(α = .05). Second, the variable that showed a significant difference through t-test was set as the dependent variable, and the ankle flexibility, gender difference, and Q-angle were designated as independent variables to use Multiple Linear Regression(α =. 05). As a result of this study, it was found that the group that experienced an ankle joint injury was found to use a landing strategy and technique through adduction of the ankle joint and internal rotation of the knee joint, unlike the group without an injury. It was also confirmed that this movement increases the extension moment of the ankle joint and decreases the extension moment of the hip joint. In particular, it was found that the dorsi flexion flexibility of the ankle affects the ankle and knee landing strategy, and the gender difference affects the ankle extension moment. Therefore, it was confirmed that physical characteristics factors affecting ankle joint injuries during one leg drop landing.

The purpose of this study was to investigate the incidence of sports injury and trend of incidence pattern of national judo athletes. The research method was analyzed based on the records of all injuries experienced by national judo athletes during training and competition for 9 years from 2008 to 2016. A total of 20,345 sports injuries requiring physical therapy were 10,768 (52.93%) for women, 9,577 (47.07%) for men, lower extremities 9,688 (47.62%), upper limbs 5,807 (28.54%), and trunk 4,850 (23.84%) and knee-related injuries (27.82%) occur more frequently than other injuries. Shoulders, feet and back were more frequent in male athletes, and ankle, neck and hand injuries were more common in female athletes. Using the binomial trend line, the trend of the decrease of sports injuries in each area was shown. However, infrequent injuries such as hands and hips tend to increase gradually. The results of this study are expected to be used as a training program for judo athletes' sports injury and basic data.

Background: This study was performed to review the efficacy of national and international randomized controlled trials (RCT) investigating Chuna manipulative treatment for ankle sprains. Methods: Online databases (PubMed, Cochrane, EMBASE, CNKI, NDSL, OASIS), were searched for studies where Chuna treatment was performed for ankle sprains up to October 12th, 2017. Only RCT were selected that fulfilled the inclusion/exclusion criteria. Data were analyzed using the Cochrane risk of bias tool. Results: There were 676 studies retrieved from the databases, resulting in analysis of 24 RCT. There was an average of 7 treatment visits over a 7 day period and the most frequent evaluation tool used was efficacy rate, with drug therapy being the most common control used in the trials. In 15 RCT, several Chuna methods were used in combination, amongst which, the osteopathic technique was most common. Statistically significant improvement in evaluation indices was reported in 19 RCT, and in 3 RCT, statistically significant improvement was reported, but not for all indices. In the remaining 2 RCT, there were no significant differences in any of the evaluation indices. No adverse reactions were reported in any of the RCT, although it was unknown whether all the trial protocols indicated that adverse reactions should be monitored, and for this reason, the risk of bias was unclear. Conclusion: The review of 24 studies suggest that Chuna manipulative treatment for ankle sprains was effective in most cases, although, potential bias in these studies was difficult to evaluate.
