Background: The study aimed to examine changes in muscle activity by measuring the Q-angle and lower extremity activity when going down the stairs, after the application of either Mulligan taping or flossing bands to patients with chronic ankle instability. Methods: A total of 19 men with chronic ankle instability in their 20s and 30s participated in the study. Participants were randomly divided into two groups: the Mulligan taping group (n = 9) and the flossing band group (n=10). The Mulligan taping group had three sets of Mulligan joint operations repeated 10 times, after which the Mulligan tape was applied. The flossing band group either performed functional activities or exercised for 2 minutes after flossing band application. After the application of either Mulligan taping or flossing bands, changes in the Q-angle and lower limb muscular activity while going down the stairs were measured and compared. Results: In the Mulligan taping group, the Q-angle significantly decreased from 13.63° to 12.7° during the step down. Similarly, the Q-angle of the flossing band group significantly decreased from 15.95° to 15.48° (p<.05). There was no difference in lower limb muscle activity between the two groups when going down the stairs. The muscle activity of the tibialis anterior significantly increased from 34.12% to 40.2%, and the difference between the two groups were statistically significant (p<.05). Conclusions: The study found that the application of Mulligan taping and flossing bands to patients with chronic ankle instability decreased the Q-angle and lower limb muscle activity when going down the stairs.

We performed lateral ankle ligament reconstructions using Achilles allograft on patients who had failed previous Brostrom repair. The bone plug is fixed with an interference screw into the calcaneus, the tendon graft is passed through a fibular tunnel, and then anchored into the talus with the biotenodesis screw. The graft is strong enough to maintain joint stability until graft incorporation and remodeling occurs. In patients with chronic failed lateral ankle instability requiring graft for ligament reconstruction, this technique allows anatomic reconstruction without the need to sacrifice autogenous peroneal tendons.

Purpose: The purpose of this study was to investigate the relationship between hip abductor muscle strength and lumbar instability in patients with chronic low back pain. Methods: Fifty-two female patients were recruited for this study. The patients' history was recorded and was used to determine the general characteristics of the female complaints. The women were additionally examined to determine whether the level of pain was characteristic of patients with chronic lumbar instability. The following tests were also carried out in the subjects during the examination: 1) the prone instability test. 2) the test for aberrant movement patterns during lumbar flexion test. 3) the straight leg raising test. 4) posterior-to-anterior mobility test, and 5) the test for age and strength of the hip abductor muscle following assessment of the dominant side. In particular, hip abductor muscle strength was evaluated using a dynamometer. Results: The test results showed that the number of positive responses for the five types of lumbar instability tests performed, was significantly related to the strength of the hip abductor muscle. The average hip abductor muscle strength in total subjects was $72.89{\pm}7.66N$, whereas the average hip abductor muscle strength in subjects who showed positive responses to more than four out of the five tests, was $44.70{\pm}5.79N$. Conclusion: The results demonstrated that the hip abductor muscle strength and lumbar instability were negatively correlated. The lower was the strength of the hip abductor muscle, the higher was the possibility of lumbar instability.

본 연구는 만성 발목 불안정성을 가진 엘리트 선수들을 대상으로 8주간의 엉덩이 강화 운동이 엉덩이의 근력 및 족압 분포도의 변화에 어떠한 영향을 미치는 지를 분석하기 위해 실시되었다. 발목에 최소 2회 이상의 발목 염좌를 진단받은 만성 발목 불안정성의 대상자 19명을 대상으로 8주간의 엉덩이 강화 운동을 실시하였으며, 결과에서 엉덩이 강화 운동으로 엉덩이의 외전근력은 유의한 증가를 보였지만 족압의 분포도와 증가비율은 유의한 변화를 보이지 않았다. 이 결과는 운동 후, 환측과 건측의 근력과 족압분포의 차이가 나타나지 않아 환측의 근력과 족압분포가 건측의 수준만큼 증가된 것으로 생각되며 이는 8주간의 엉덩이 강화 운동이 발목의 불안정의 개선에 일정정도 효과가 있는 것으로 사료된다. 이러한 결과를 토대로 만성 발목 불안정성을 가진 대상자들의 회복과 재발방지를 위한 재활운동 프로그램의 구성요인으로서 엉덩이 외전근력 강화와 족압 분포도에 대한 부분을 중요하게 반영하는 것이 효과적일 것으로 사료된다.

Objective: The purpose of this study was to identify the effect of reduced plantar cutaneous sensation on gait kinematics during walking with and without CAI. Method: A total of 20 subjects involved in this study and ten healthy subjects and 10 CAI subjects participated underwent ice-immersion of the plantar aspect of the feet before walking test in this study. The gait kinematics were measured before and after ice-immersion. Results: We observed a before ice-immersion on plantar cutaneous sensation, CAI subject were found to reduced ankle dorsiflexion, knee external rotation, hip adduction, and internal rotation compared to control subject. After ice-immersion, CAI subjects were found to reduce knee external rotation, hip adduction. However, no significant ankle joint kinematics. Conclusion: While walking, gait pattern differences were perceived between groups with and without plantar cutaneous sensation. The results of the study may explain the abductions in the hip angle movements in CAI patients at initial contact compared to healthy subjects in the control group when plantar cutaneous sensation was reduced. A change in proximal joint kinematics may be a conservative strategy to promote normal gait patterns in CAI patients.

Objective: To quantitatively assess biochemical alterations in the cartilage of the subtalar and midtarsal joints in chronic lateral ankle instability (CLAI) patients with isolated anterior talofibular ligament (ATFL) injuries and combined calcaneofibular ligament (CFL) injuries using MRI T2 mapping. Materials and Methods: This study was performed according to regulations of the Committee for Human Research at our institution, and written informed consent was obtained from all participants. Forty CLAI patients (26 with isolated ATFL injuries and 14 with combined ATFL and CFL injuries) and 25 healthy subjects were recruited for this study. All participants underwent MRI scans with T2 mapping. Patients were assessed with the American Orthopedic Foot and Ankle Society (AOFAS) rating system. The subtalar and midtarsal joints were segmented into 14 cartilage subregions. The T2 value of each subregion was measured from T2 mapping images. Data were analyzed with ANOVA, the Student's t test, and Pearson's correlation coefficient. Results: T2 values of most subregions of the subtalar joint and the calcaneal facet of the calcaneocuboid joint in CLAI patients with combined CFL injuries were higher than those in healthy controls (all p < 0.05). However, there were no significant differences in T2 values in subtalar and midtarsal joints between patients with isolated ATFL injuries and healthy controls (all p > 0.05). Moreover, T2 values of the medial talar subregions of the posterior subtalar joint in patients with combined CFL injuries showed negative correlations with the AOFAS scores (r = -0.687, p = 0.007; r = -0.609, p = 0.021, respectively). Conclusion: CLAI with combined CFL injuries can lead to cartilage degeneration in subtalar and calcaneocuboid joints, while an isolated ATFL injury might not have a significant impact on the cartilage in these joints.

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.

Background: To evaluate the effect of Kinesio taping applied on the ankle instability, joint range of motion and balance. Methods: The participants included in this study were male and female, 20~30 ages, who experiencing an ankle sprain or had chronic pain, did not exercise during the intervention, and did not experience severe exercise at least 3 weeks before. A total of twenty-four participants were divided into two groups: Kinesio taping applied group (n=12) and control group (n=12). The experiment was conducted for a three days. Measurements were taken for ankle joint range of motion using goniometer, and measurements were taken for balance using good balance system. Pre-test measurements were conducted on before Kinesio taping apply, and 24 hours after, 48 hours after, 72 hours after measurements were conducted. Statistical analysis was done using a independent samples t-test and repeated measure ANOVA. Results: There were significant differences to the duration of intervention in ankle joint range of motion and balance within the both group. However, there was a significant differences Kinesio taping group when comparing the groups. Conclusions: According to the results of this study, applying Kinesio taping to ankle instability is more effective on ankle joint range of motion and to recover balance.

Purpose: To evaluate the efficacy of the arthroscopic exploration combined with modified Brostrom operation (MBO) for the treatment of chronic lateral ankle instability (CAI). Materials and Methods: Sixty patients who diagnosed a CAI were performed MBO. We divided to 2 groups, whether simultaneously inspected by arthroscopy (group B) or not (group A). The both group's results were compared according to American Orthopedic Foot and Ankle Society Ankle-hindfoot score (AOFAS), functional ankle score and visual analog scale (VAS) at preoperative and final follow-up period. Results: There were no significant differences of AOFAS, functional ankle score and VAS between both groups at final follow-up. However, in group A, 2 cases associated with medial ankle instability and syndesmotic injuries were did not diagnosed preoperatively, showed poor prognosis. In group B, one case had a permanent peroneal nerve symptom. The match rate of intra-articular lesions between preoperative diagnosis and postoperative arthroscopic diagnosis was 30% in group B. Conclusion: Combination of arthroscopic exploration and MBO is effective strategy for intra-operatively discrimination of intra-articular associated lesions for CAI.

본 연구의 목적은 농구동호인의 만성발목관절불안정성(CAI)에 따른 한발착지패턴의 변화를 확인하고 비교분석하고자 하였다. 현재 부산광역시에서 레크레이션 농구경기에 참여하고 있는 농구동호인 30명을 대상으로 국제발목협회에서 제공하는 CAI 표준 선정기준에따라 CAI집단 21명과 CON집단 9명으로 분류하였다. 한발착지패턴을 측정하기 위해 초기접촉 시점 및 무릎관절 최대 굽힘 시점에서 하지정렬과 관절 움직임을 측정하고 초기접촉 시점, 발꿈치접촉 시점 및 무릎관절 최대 굽힘 시점에서 앞정강근, 긴종아리근, 안쪽장딴지근 및 중간볼기근의 활성도를 측정하였다. 그 결과, 집단 간 단일 다리 드롭랜딩 시 하지정렬과 하지 근활성도는 유의한 차이를 보이지 않았다. 이런 결과는, CAI에 따라 한발착지패턴과 근활성도에 유의한 차이가 없다는 것을 보여주었다. 추후 연구에서는 CAI를 세부적으로 구분하고 경기포지션을 고려하여 움직임의 특성 및 기능적 요구의 차이를 반영해야 할 것으로 생각된다.
