Purpose: The purpose of this study was to investigate the effects of the fascia distortion model (FDM), one of the fascia treatments, on unstable ankle subjects. This was done through the chronic ankle instability tool (CAIT) questionnaire on maximum isometric muscle strength, proprioception, dynamic balance, and maximum angle. Methods: An experiment was conducted using the chronic ankle instability tool questionnaire on males and females in their twenties who suffered from ankle instability. Before the experiment, maximum isometric strength, proprioceptive, dynamic balance, and maximum angle were measured. The fascia distortion model was applied and then measurements were taken again to compare and analyze the changes. Analysis was carried out using the paired t-test. Results: After applying the fascia distortion model, maximum isometric strength, proprioceptive, dynamic balance, and maximum angle significantly improved (p<0.05). Conclusion: This study found that the fascia distortion model method was effective in improving maximum isometric strength, proprioceptive, dynamic balance, and maximum angle. The results suggest that the fascia distortion model method is a new intervention that could be used for subjects with chronic ankle instability.

Objective: The purpose of this study was to investigate the effects of neuromuscular training of ballet dancers with chronic ankle instability on ankle stability and posture controlability. Design: A randomized controlled trial. Methods: A total of Thirty-twoyoung female ballet dancers with chronic ankle instability have voluntarily participated in the study. The participants were randomized to the neuromuscular training group(n₁=11), elastic resistance squat group(n₂=11), and control group(n₃=10). The intervention was applied to a total of 18 exercises per six weeks and conducted in each group for one hour a day, three times a week. All subjects were evaluated for Cumberland ankle instability tool(CAIT), static balance at before-after intervention. Results: In the comparison of the effects within the groups, the effect of the intervention on CAIT and posture control was significantly increased in the neuromuscular training group and elastic resistance squat group (p <0.05). In the comparison of the effects between the groups, the neuromuscular training group, and elastic resistance squat group were found to significantly increase more than the control group (p <0.05). The effect of ankle stability is similar in neuromuscular training and elastic resistance squat training, neuromuscular training is more effective in improving posture control rather than elastic resistance squat training. Conclusions: When planning a rehabilitation training program for a ballet dancer with chronic ankle instability, neuromuscular training can be applied as an intervention method to improve ankle stability and posture control ability.

Purpose : The purpose of this study is to compare the balance ability between subjects with chronic ankle instability and normal people and the center of pressure displacement during the sit to stand and stand to sit. Methods : The subjects of this study were 63 who met the inclusion criteria and were classified into normal group (n=33) and chronic ankle instability group (n=30). The displacement of the center of pressure during sit to stand and stand to sit was measured. And the limit of stability and Y-balance tests were performed to measure the balance ability. Independent t-test was conducted to compare center of pressure displacement and balance ability between groups, and pearson correlation was conducted to analyze the correlation between the center of pressure displacement and balance ability. Results : In the case of the center of pressure displacement, there was a significant difference between the two groups during sit to stand and stand to sit. In the case of balance, both limit of stability and Y-balance test showed significant differences between the two groups. At the time of sit to stand, the center of pressure displacement showed a significant correlation with balance abilities, and at the time of stand to sit, the center of pressure displacement showed a significant correlation with Y-balance test. Conclusion : Chronic ankle instability shows that there is a lot of sway in the body due to compensation to replace the decrease in ankle joint range of motion when performing sit to stand and stand to sit due to sensory input damage such as decrease in ankle range of motion and decrease in ankle proprioception. Chronic ankle instability is expected to have a negative effect on our daily lives in life. The results of this study will serve as the basis for the dynamic approach to objective evaluation, treatment, and prevention of chronic ankle instability.

Severe ankle sprain secondarily leads to chronic lateral ankle instability in 20-30%. Many surgical procedures have been presented for reconstruction of the lateral ankle instability, but controversy still remains for the ideal surgical option. Br$\ddot{o}$strom procedure or its modifications have been widely used but they have some limitations for the instabilities for the over-weight, physically high demanding patients and especially for significantly deficient or attenuated ligaments. Moreover the tenodesis procedures using peroneus brevis tendon are non-anatomical and sacrifice important lateral stabilizing tendon. Therefore recently, many reconstructive procedures for lateral ankle instability utilizing free allograft or autograft tendon have been introduced to anatomically stabilize the lateral ligaments to various degrees.

PURPOSE: The aim of this study was to compare the effect of whole body vibration stimulation on ankle instability, ankle range of motion, and balance ability in adult with chronic ankle instability. METHODS: Forty-five adult with chronic ankle instability were randomly equally allocated the I group (whole body vibration stimulated at 10 Hz), or the II group (20 Hz), or the III group (25 Hz). All the participants (male:13/female: 32, age: $26.64{\pm}3.14$) in this study received whole body vibration therapy for an additional 15 minutes after hot pack and ultrasound three times a week for four weeks. Outcome were measured before and after 4 weeks training. RESULTS: All the three groups showed significant differences in AII and CAIT after intervention (p<.05). I group showed the most significant difference (p<.05). All the three groups also showed significant increase in ankle dorsiflexion and plantar flexion after training (p<.05). I group showed greater increase than the other groups in ankle dorsiflexion (p<.05). The X-axis, Y-axis, and fluctuation speed were significantly decreased in the three groups (p<.05), but there was no significant difference between the three groups after the intervention. CONCLUSION: The findings suggest that the whole body vibration stimulation according to various frequencies is effective for improve ankle instability, ankle range of motion and balance ability in adult with chronic ankle instability. 10 Hz whole body vibration stimulation could help improve ankle instability and ankle range more effectively than other frequencies.

The term chronic lateral ankle instability (CLAI) embraces a spectrum of conditions that involve functional and mechanical instability, both in athletes and lower-demand patients. The hallmarks of CLAI are recurrent sprains, persistent pain, and repeated episodes of the ankle giving way. CLAI is the main complication of acute ankle sprains, which can cause discomfort in daily and sports activity. Approximately 10% to 30% of patients with acute ligament ruptures will develop chronic instability over the course of a year from the index injury. An accurate diagnostic approach and successful treatment plan should be established based on a comprehensive understanding of the concept of functional and mechanical instability. Unfortunately, the optimal modality for the management of CLAI is unclear. Even after conservative treatment or surgical intervention, it could result in degenerative changes to the ankle joint in the long term. Thus far, the incidence of ligamentous posttraumatic ankle osteoarthritis was reported to be 13% to 78%. The mean latency time between injury and osteoarthritis was at least 10 to 34.3 years. CLAI is an important pathological condition that can cause discomfort or dysfunction in daily activity in the short term, resulting in joint destruction in the long term. Therefore, it is important to understand the various complications that can occur when CLAI is not treated properly.

PURPOSE: This study investigated the effect that an elastic therapeutic taping treatment given to patients with chronic ankle instability had on the vertical ground reaction force, center of pressure, and range of motion in the ankle, knee and hip joints, during a Cross-cutting movement from landing. METHODS: This study analyzed 12 able-bodied adults and 12 patients with chronic ankle instability classified by using the Cumberland tool in the motion analysis laboratory, Hanseo University. The experiment was conducted under two conditions elastic taping and no treatment. In order to analyze the difference between the groups. An independent t-test was performed at p>.01. RESULTS: Plying an elastic therapeutic taping to the patients with chronic ankle instability significantly decreased the range of joint motion in the inversion of the ankle joint, the flexion of the knee joint, and the flexion and internal rotation of the hip joint during a cross-cutting movement from landing in comparison with the able-bodied adults p<.01. This restriction in the range of motion decreased the center-of-pressure trajectory length of patients with chronic ankle instability p>.01. CONCLUSION: An elastic therapeutic taping treatment given to patients with chronic ankle instability causes ankle stability to increase during a cross-cutting movement from landing.
