Purpose: We analyzed the ankle bony abnormality of patients with marked ankle instability who had chronic ankle sprain more than 3 years. Materials and Methods: We evaluated the chronic ankle sprain (more than 3 years) patients with marked ankle instability tested by varus stress test and anterior draw test from March 2000 to December 2005. Eighty-nine patients (104 ankle) were evaluated and there were 38 males and 51 females. The mean age of patient at the time of diagnosis was 34.5 (range, 18 to 56 years). The average duration of morbidity was 7 years and 3 months (range, 3 years and 3 months to 21 years). The patients who had history of dislocation, fracture, malalignment, operated patients, and rheumatoid ones were excluded. Plain radiographs of AP, lateral, oblique and mortise view were checked. Results: Radilologic abnormalities were found at 74 ankles (71%) among 104 ankles. Frequent sequences of location were anterior talotibial osteophyte, medial malleolar osteophyte, Os subfibulare, lateral malleolar osteophyte. Posteior osteophyte, ankle arthritis, talar articular defect were rarely found. Conclusion: Seventy-one percent among patients with chronic ankle sprain and marked ankle instability showed more than one radiologic abnormalities. Thus, more exclusive and accurate ankle examination should be performed in these patients.

Purpose: This retrospective study was designed to determine the type and frequency of associated lesions in patients with chronic lateral ankle instability who had modified Brostrom lateral ankle ligament reconstruction. Materials and Methods: Between 2004 and 2007, 60 cases of 60 patients were enrolled in this study. A retrospective review of the magnetic resonance images of the affected ankle was conducted by two orthopedic surgeons who did not get any information about intraoperative findings and the lesions were admitted when two doctors were coincident. Results: The overall incidence of associated lesions found in this study was about 83%. Peroneal tenosynovitis was the highest frequency (32%), followed by osteochondral lesion of talus (28%), anterolateral impingement (15%), Os subfibula (13%), Os trigonum (12%), ankle synovitis (12%), anterior tibiofibular ligament tear (15%), anterior bony spur (7%). Another findings were loose bodies (5%), flexor tendon tenosynovitis (5%), medial osteophyte (3%). Conclusion: Identifying these associated lesions will be helpful in treating chronic lateral ankle instability especially when the surgeon have a plan to operate the instability. We suggest that the better results can be obtained when the associated lesions are corrected simultaneously.

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.

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.

We investigated the effects of a Virtual reality(VR) program on the proprioception and instability of functional ankle instability(FAI) patients. Among the 20s old individuals who lived in Republic of Korea; 20 people were selected through a public participation process. The 20 participants were then randomly divided into two groups, one of strength exercise(n=10) and one of balance exercise(n=10). Of the patients who had experienced an ankle sprain in the past and currently felt ankle instability, those who recorded 24 points or less on the Cumberland ankle instability tool(CAIT) were determined to have FAI. We selected the strength exercise and balance exercise in the Nintendo Wii Fit Plus as a VR program. The subjects used the program on the Wii Balance Board three times per week for 20 minutes and total 10-minute warm-up and down for four weeks. Proprioception and CAIT of the balance exercise group were improved significantly after the exercise compared to before the exercise(p<.05). Authors recommend that the balance exercise in the VR program be used as an aid for physical therapeutic intervention.

Purpose : Kinesio taping applied to the ankle varies, and if the overall ankle is taped as much as possible, several effects, including balance, can be expected, but clinically the cost reduction for intervention is very important. Therefore, this study attempted to find out the optimal way to the effect and cost of kinesio taping on ankle dynamic balance. Methods : The subject of this study was 24 university students in their 20s (male: 13, female: 11), who received sufficient explanation of the purpose and method of the study. The Cumberland ankle instability tool (CAIT) questionnaire was used for the degree of ankle instability of the study subjects. If the subject's CAIT score was 28 points or more, it was classified as a stable ankle, and if the score was 24 points or less, it was classified as functional ankle instability (FAI). In this study, Biodex Balance System^® measurement equipment was used to calculate the dynamic balance of study participants. The application of kinesio taping was performed by one physical therapist to attach in the same way, and a method of wrapping the ankle joint was applied in the eight-shaped bandage. Results : The results are as follows in before and after taping of the stable ankle and FAI group. There was no significant difference in the overall, anterior-posterior, and medial-lateral stability index. The comparison is as follows between groups for the differences (post-pre value) in before and after the application of kinesio taping. There were no significant differences between groups in all the overall, anterior-posterior, and medial-lateral stability index. Conclusion : In this study, no significant difference in kinesio taping was found in the dynamic balance of stable ankle and FAI (overall, anterior-posterior, and medial-lateral). It is necessary to continue to study ways to find the maximum effect while minimally attaching them to the application method of ankle kinesio taping.

Physical examination and surgical findings and symptoms are often inconsistent with magnetic resonance imaging (MRI) findings when diagnosing chronic ankle lateral ligament instability, and confirmed surgical findings are used as the gold standard in most clinical studies. Anterior drawer testing is considered unreliable because normal findings are highly variable, and its accuracy ranges from 50% to 100%. Furthermore, radiographic stress imaging, such as in anterior drawer stress view, is performed under manual stress or using a stress device, and its findings also vary widely and confuse when interpreting stress views. The average accuracy of MRI findings is around 85% (range, 66%~91.7%), and thus, cannot be used as a primary indicator for surgery. For patients with suspected lateral ankle ligament instability, based on symptoms and physical examination findings, MRI may be useful for identifying lesions in ankle joints and for differentiating them from other conditions.

Patients with chronic lateral ankle instability often experience a range of associated injuries. The well-known comorbidities include intra-articular pathologies (osteochondral lesion, soft tissue or bony impingement, and loose body), peroneal tendon pathologies, neural injuries, and other extra-articular pathologies. Surgeons should have a high index of suspicion for these associated pathologies before operative intervention, correlate the clinical findings, and plan the treatment. Despite the restoration of ankle stability following ligament repair or reconstruction surgery, a high prevalence (13%~35%) of postoperative residual pain has been reported. This pain can negatively affect the clinical outcomes and patient satisfaction. This study examined the causes of persistent pain after surgical treatments for chronic ankle instability.

Purpose: We try to retrospectively analyze the clinical results of the modified Chrisman-Snook procedure for chronic ankle instability. Materials and Methods: From November 1997 to April 2006, thirty-one patients who underwent modified Chrisman-Snook procedure for chronic ankle instability were analyzed. All patients were male and the mean age was 31 years. The follow-up period averaged 48 months. We evaluated the clinical results measured by Hasegawa method. Results: Among them, there were soldiers in 11, socker players in 6, patients who weigh more 80 kg in 5. And there were 9 patients who previously underwent modified Brostrom procedure for chronic ankle instability. The clinical results were rated as excellent in 29, fair in 2 who did not cooperate with postoperative rehabilitation program. There were complications of 2 cases of irritation of the sural nerve and recurrence respectively, 1 case of wound problem. Conclusion: Our results show that the modified Chrisman-Snook procedure is effective treatment method for patients with high-performance athlete/soldier or failed modified Brostrom procedure.

Purpose : Using a smartphone while walking districts attention and increases the risk of losing balance or falling. Ankle instability is caused by decreased muscle strength and decreased neuromuscular ability leading to postural control problems. Dual tasks increases the risk of falls by reducing postural control in adults with ankle instability. This study aimed to investigate the effect of performing a dual task on balance and muscle activity in adults with ankle instability using a smartphone. Methods : Forty-nine individuals with ankle instability participated in this study. A game of finding the wrong picture was performed using a smartphone in the dual task, and only looking at the blank screen of a smartphone was evaluated in the single task. The participants randomly performed single and dual task to evalutate balance and muscle atcitivy. Balance was evaluated using the Biodex balance system (BBS), and muscle activity was evaluated using surface EMG. Muscle activity of the gastrocnemius and tibialis anterior was measured at the same time as balance. Results : The results of this study showed that overall, anteior/posterior, and medial/lateral balance indices all showed significant differences when performing the dual task compared with those during the single task (p<.05). The muscle activity results showed a significant difference compared with that of the gastronemius muscle on the nondominant side during the dual task (p>.05). Conclusion : The results of this study showed that maintaining balance is more difficult when performing the dual task than during the single task, and only the muscle activity of the nondominant gastrocnemius muscle decreased. The dual task causes a decrease in concentration for postural control, which negatively affects postural stability. Individuals with ankle ankle instability should refrain from performing dual tasks, such as using smartphones, to prevent ankle damage.
