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 theⅠgroup (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±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.

PURPOSE: This study aimed to identify differences in ankle laxity in chronic ankle instability (CAI), coper, and control groups, and a correlation between ankle laxity, self-reported function, and perceived instability. METHODS: Sixty-six participants (22 CAI patients, 22 copers, and 22 controls) selected by recommendations of the International Ankle Consortium volunteered for this study. Foot and Ankle Ability Measure Activities of Daily Living (FAAM-ADL), FAAM-Sports, and Ankle Instability Instrument (AII) were used to assess participants’ self-reported function and perceived instability. The FAAM-ADL and FAAM-Sports are reported as a percentage. Higher scores indicate better function. The AII is reported as “yes” responses while more “yes” responses indicate higher instability. Three trials of anterior/posterior (A/P) displacement and inversion/eversion (I/E) displacement were assessed by an instrumented ankle arthrometer. Greater displacement indicates higher laxity. The ankle positioned in sagittal- and frontal-plane neutral while A/P and I/E displacement were assessed with 125 N and 4 N-m, respectively. The means of three trials were used for data analysis. One-way ANOVA and Tukey post-hoc comparisons (α=0.05) were performed to identify differences in ankle laxity between groups. Pearson correlation analysis was performed to identify a relationship between ankle laxity, self-reported function, and perceived instability. RESULTS: CAI patients show greater A/P displacement compared to control group (p<.03), and greater I/E displacement compared to coper and control groups (p<.03). Several positive and negative correlations were found between ankle laxity, self-reported function, and perceived instability (p<.00). CONCLUSIONS: As self-reported function and perceived instability are correlated with greater laxity (I/E displacement), improving static stability (ankle laxity) may play an important role in improving perceived ankle function and instability in CAI.

Background: Ankle sprains, and the resulting ankle instability worsen to chronic due to recurrent ankle injuries or sprains, 78% of which are accompanied by posture instability and damage due to changes in the position of the talus of the ankle. The purpose of this study is to investigate the immediate effect of applying MWM taping on the patient's muscle strength and balance ability in patients with chronic ankle instability. Methods: 15 people with MWM taping and 15 people with Kinesio taping were applied, and after applying the taping of the ankle, 10 minutes of walking treadmill and 10 times of forward lunge operation, the change in ankle muscle strength and balance ability was confirmed. The strength test of the ankle was performed using a test device called Biodex system 4 (USA) for the movement of the dorsi-flexion and plantar flexion of the foot, and the balance of the two groups was measured using Biodex balance system (USA) to test balance ability. Results: The comparison of muscle strength changes in the ankle does not show a significant increase in the group applying MWM compared to the group applying kinesio taping (p<.05). In the comparison of equilibrium capabilities, the MWM taping group also showed a significant increase in the MWM taping group compared to the kinesio taping group (p<.05). Conclusion: When applying MWM taping and kinesio taping to patients with chronic ankle instability, there was no significant difference in comparison of muscle strength changes, but there was a significant difference in comparison of balance ability.

Objective : The purpose of this study is to determine the effect of the ankle disk training on the contraction pattern of peroneous longus and tibialis anterior muscles of the patients with functional ankle instability resulted from repeated inversion injury. Method : Fourteen patients with functional ankle instability and fourteen age-matched healthy subjects participated in this study. With attaching surface electrode to the peroneous longus and tibialis anterior muscles, inversion moment at the ankle was induced by a platform with trap door. While inducing inversion moment, onset time of contraction of the two muscles was assessed and compared by electromyography(EMG). And the changes in onset time of contraction between pretraining and post-six-week ankle disk training were assessed. Results : In experimental group, the onset time of contraction of the peroneus longus muscle during inversion moment was significantly slower than that of tibialis anterior muscle(p<0.05). And the difference of the onset time of contraction between peroneus longus muscle and tibialis anterior muscle was positively correlated with the number of time of injury(p<0.05). The onset time of contraction of the peroneus longus muscle in both stable and unstable ankle after the six-week ankle disk training became significantly short(p<0.05). Conclusion : This study examined the effect of ankle disk training as one form of proprioceptive training on muscle reaction times, and its results my explain why such training can help protect aganist further ankle sprain in patients with functional ankle instability.

PURPOSE: This study examined the comparative effects of an ankle sensorimotor training program combined with hip strengthening exercise (ASTPCHSE) and ankle sensorimotor training program (ASTP) alone on muscle strength, static balance, and dynamic balance in individuals with functional ankle instability. METHODS: Sixteen research participants with functional ankle instability were enrolled in this study. The participants were divided randomly into the ankle sensory motor training program group and the ankle sensory motor training program combined with the hip strengthening exercise group. Each group performed a series of exercise programs two times per week for four weeks. The Cumberland ankle instability tool (CAIT) was used to measure the participants’ functional ankle instability. A Balance trainer 4 was applied to assess the static and dynamic balance, and a Primus RS multimodal dynamometer was used to evaluate the muscle strength. RESULTS: No significant differences in static balance, dynamic balance, and muscle strength were found between the ASTP and ASTPCHSE groups (p > .05). On the other hand, the dynamic balance and muscle strength improved in the ASTP and ASTPCHSE groups after the intervention (p < .05). The static balance was not enhanced in both groups after the intervention (p > .05). CONCLUSION: Ankle exercise and an ankle sensorimotor training program combined with hip strengthening exercise are effective in improving muscle strength and dynamic balance in individuals with ankle instability. On the other hand, there are no meaningful differences between ankle exercise and ankle and hip combined exercise.

Background: The multiple hop test is an active performance test that has been commonly used to assess individuals with functional ankle instability. Previous studies have suggested that insufficiency of dynamic postural stability and passive stability during dynamic activities can have an influence on performance in the multiple hop test. However, no study has investigated the effects of dynamic postural stability training and ankle bracing on multiple hop test performance in individuals with functional ankle instability. Objects: The purpose of this study was to compare the immediate effects of dynamic postural stability training versus ankle bracing in the performance of the multiple hop test for participants with functional ankle instability. Methods: Twenty-nine participants with functional ankle instability who scored below 24 in the Cumberland Ankle Instability Tool were selected. The participants were randomly divided into two groups: a dynamic postural stability training group (n1=14) and an ankle bracing control group (n2=15). The multiple hop tests were performed before and after applying each intervention. Dynamic postural stability training was performed using visual-feedback-based balance-training equipment; participants in this group were asked to perform a heel raise in a standing position while watching the centering of their forefoot pressure to prevent excessive ankle inversion. Ankle bracing was applied in the control group. Results: When comparing the pre- and post-intervention period for both groups, both methods significantly improved the results of the multiple hop test (p<.05). However, no significant differences were shown between the dynamic postural stability training and ankle bracing groups (p>.05). Conclusion: Both dynamic postural stability training and ankle bracing showed significant improvement(2.85 seconds and 2.05 seconds, respectively) in test performance. Further study is needed to determine the long-term effects of dynamic postural stability training and to determine whether insufficient dynamic postural stability is a causative factor for functional ankle instability.

박시은,김기종 한국신경근육물리치료학회(구 한국신경근육재활학회) 2021 한국신경근육재활학회지 Vol.11 No.3

The aim of this study is to find out the immediate effect of kinesio taping on static balance for stable ankles and functional instability ankles in general adults, and whether kinesio taping affects stable ankles as well as functional instability ankles. Twenty-two healthy adults were selected and divided into two groups(stable ankle group and functional instability ankle group) according to the Cumberland Ankle Instability Tool (CAIT). If the subject's CAIT score is 28 or higher, it is classified as a stable ankle, and if the CAIT score is 24 or lower, it is classified as a functional ankle instability. To determine the effectiveness of kinesio taping, the static balance ability(overall, anterior-posterior, and medial-lateral stability index) was measured by the Biodex Balance System®. As a result, there was no significant difference on the static balance between before and after application of kinesio taping in both groups. And there was no significant difference between stable ankle and functional instability ankle groups. These results indicate that kinesio taping on stable and functional instability ankles for healthy adults has no immediate effect on static balance. In future studies, it will be necessary to examine the short-term and long-term effects of kinesio taping on elderly and subjects with ankle injuries.

Objectives: The purpose of this study was to suggest a more effective exercise method for chronic ankle instability by comparing an effect of strengthening exercise and the balance exercise. Methods: After recruiting 24 people in their 20s with chronic ankle instability(CAI) and dividing them into two groups. The control group performed strengthening exercises(calf raise, heel walks and theraband exercise) three times a week for four weeks for 30 minutes. In the experimental group, they conducted a combination of ankle strengthening exercises and balance exercises(dumbbell cross exercise, BOSU Exercise) three times a week for four week s for 40 minutes. We measured ankle instability index, muscle strength, and balancing abilities before and after the training. Results: In both the experimental group and the control group, there was a significant difference in the Cumberland ankle instability tool(CAIT), static balance before and after the intervention(p< .05). But there was no significant difference between the two groups(p >.05). In the dynamic balance, the experimental group had significant differences (p< .05). However, the control group had no significant difference(p >.05). There was no statistically significant difference in the outcomes both the experimental group and control group(p>.05). Conclusions: We propose that ankle strengthening exercises and balance exercises can be an effective clinical exercise method to improve the ankle instability and balance ability of people with ankle chronic ankle instability.
