  • PURPOSE: The purpose of this study was to examine the immediate changes in the weight-bearing ankle dorsiflexion range of motion (ROM) and the dynamic balance in asymptomatic subjects using the modified Star Excursion Balance Test (SEBT) after ankle balance taping (ABT) and placebo ABT with kinesiology tape METHODS: A total of 23 active participants (11 men, 12 women) volunteered for this study. Ankle flexibility was assessed using the weight-bearing lunge test, and dynamic balance was assessed using the modified SEBT. Participants were asked to respond to questions regarding their perception of stability, reassurance, and confidence when performing modified SEBT. RESULTS: The weight-bearing ankle dorsiflexion ROM did not show a significant decrease after real ABT or placebo ABT compared to the ROM prior to ABT. The anterior, posterolateral, and posteromedial reach distances of SEBT did not increase significantly after real ABT or placebo ABT compared to the distances prior to ABT. However, the participants' perception of stability, reassurance, and confidence, when performing SEBT with real ABT, was increased compared to that during the control trial. CONCLUSION: This study showed that although real ABT did not immediately improve the reach distances in the 3 directions during modified SEBT, it improved the participants' perception of stability, reassurance, and confidence without decreasing weight-bearing ankle dorsiflexion ROM.

  • PURPOSE: This study examined the effect of vibration stimulation of a vibration foam roller on the change in the range of motion of the ankle joint and proprioception in patients with chronic ankle instability. An additional aim was to provide basic data for rehabilitation programs for chronic ankle instability patients. METHODS: This study was a randomized crossover design of 22 patients with chronic ankle instability. All subjects were divided into a vibrating group, a non-vibrating group, and a control group. The vibration and non-vibration groups performed the interventions, but the control group did not. For the measurement, the range of motion and proprioception of the ankle joint was measured using an electronic protractor (Electrogoniometer, BPM Pathway, UK). RESULTS: The vibration group showed significant differences in the dorsiflexion angle, dorsiflexion proprioception, and plantar flexion proprioception (p < .05). The non- vibration group showed significant differences in the dorsiflexion angle and dorsiflexion proprioceptive sensation (p < .05). The vibration group and the control group showed significant differences in dorsiflexion proprioception and plantar flexion proprioception (p < .05). CONCLUSION: The range of motion and proprioception of the ankle joint were improved in the group that received vibration stimulation after the intervention than before the intervention. Future research will be needed on patients with various diseases.

  • Objective: This study attempted to compare the effects of bridge exercise using a sling according to the angle of the ankle to confirm the effective lower extremity muscle activation posture of patients with patellofemoral pain syndrome(PFPS). Design: Cross-sectional study Methods: Seventeen patients with PFPS were recruited and the muscle activities of the vastus medialis, vastus lateralis, rectus femoris, and gluteus maximus were measured according to the ankle position (dorsiflexion, neutral, plantar flexion). After measuring the maximum number of isometric contractions of vastus medialis, vastus lateralis, rectus femoris, and gluteus maximus, bridging exercise using a sling according to each ankle posture was applied to measure lower extremity muscle activity. The evaluation was performed 3 times for 10 seconds. The three ankle postures were randomly performed and the average values were compared. Results: As a result of this study, the vastus medialis muscle showed high muscle activity in the order of dorsiflexion, plantar flexion, and neutral position bridge exercise (p<0.05). And the vastus lateralis showed high muscle activity in the order of dorsiflexion, neutral, and plantar flexion (p<0.05). However, rectus femoris and gluteus maximus did not show significant muscle activity according to the ankle posture, but muscle activity was highest in the dorsiflexion posture. Conclusions: As a result of this study, muscle activity was high in the order of vastus medialis and vastus lateralis during ankle dorsiflexion. This is thought to be a major factor that can be applied in various ways in clinical practice according to the ankle angle when treating PFPS patients.

  • PURPOSE: This study compared the effect of performing gastrocnemius stretching with and without the self-myofascial release of the sole on the active and passive ankle dorsiflexion angles and muscle tone of the gastrocnemius muscle in subjects with short gastrocnemius muscle. METHOD: A total of 23 subjects with short gastrocnemius muscles were included in this study. The study participants were divided into two experimental groups. Group A performed gastrocnemius muscle self-stretching exercises only, while group B performed self-myofascial release of the sole using a massage ball after the gastrocnemius muscle self-stretching exercises. For both groups, the active and passive ankle dorsiflexion angles were measured using a goniometer, and the tone of the gastrocnemius muscle was assessed using the MyotonPRO®. RESULTS: Within-group comparison showed that the participants in both groups A and B had significantly increased active and passive ankle dorsiflexion angles and decreased gastrocnemius muscle tone (p < .05) after performing their respective exercises. However, no significant differences in the said criteria were observed between groups A and B (p>.05). CONCLUSION: The results of this study showed that both methods were effective in increasing active and passive dorsiflexion angles and decreasing muscle tone. Thus, it is recommended to tailor gastrocnemius stretching exercises according to the patient's condition. If the patient does not experience discomfort in the plantar fasciae, it is recommended to perform the gastrocnemius stretching exercise only without myofascial release and use a massage ball afterward.

  • 본 연구의 목적은 발목관절의 발등굽힘 각도를 $0^{\circ}$, $10^{\circ}$, $20^{\circ}$로 위치하게 한 후 각 각도에서 장딴지근의 깃각 변화에 미치는 영향을 비교하여 효율적인 장딴지근 신장 각도를 제시하는 것이다. 건강한 성인 남녀 25명을 그 대상으로 하여 발목관절 발등굽힘 각도 $0^{\circ}$, $10^{\circ}$, $20^{\circ}$에서 초음파 기기를 이용하여 내측 장딴지근의 깃각을 측정하였다. 각도별 장딴지근의 깃각 변화를 알아보기 위해 반복측정분산분석을 성별에 따른 각도별 차이를 알아보기 위해 독립 t 검정을 실시하였다. 연구의 결과 발목관절의 발등굽힘 각도가 증가함에 따라 장딴지근의 깃각은 유의하게 감소하였으며, 각 각도별 사이 교호작용이 유의한 것으로 나타났다(p<.01). 각 각도별 남녀 차이 비교 결과 남성의 깃각이 더 큰 값을 보였으나 유의한 차이는 없었으며(p.>.05), 성별에 따른 발등굽힘 각도 증가에 따른 장딴지근의 깃각은 유의한 차이를 보였다(p<.01). 이러한 결과는 장딴지근 신장을 위한 발등굽힘 시 관절운동범위의 마지막 범위에서 시행하는 것이 장딴지근의 신장에 작은 각도로 시행하는 것보다 긍정적인 효과를 가져올 수 있다는 것을 의미한다. 향후 장딴지근 신장에 영향을 미치는 신장 각도, 적용 시간 등 다양한 요소들에 대한 연구가 지속되어야 할 것이다.

  • PURPOSE: There are several standard interventions for managing Achilles tendinitis, including eccentric exercise and calf muscle stretches, orthoses, electrotherapy, and taping. However, no study has determined the effect of non-elastic taping on deloading the Achilles tendon while vertical jumping. Therefore, this study determined the effect of non-elastic taping on ankle dorsiflexion and the triceps surae muscle activity while vertical jumping in healthy subjects. METHODS: The study recruited 17 participants. A motion analysis system was used to measure the angle of ankle dorsiflexion and wireless surface electromyography was used to measure the soleus and gastrocnemius activities while vertical jumping. Non-elastic taping was applied on randomized leg side. All subjects performed maximal effort vertical jumps without and with non-elastic taping, with three trials for each condition. The mean peak dorsiflexion and muscle activities during the three trials were calculated and paired t-tests were used to compare the mean values without and with non-elastic taping. Significance was defined as (p<.05). RESULTS: The maximum angle of ankle dorsiflexion and activity of the gastrocnemius muscle decreased significantly when non-elastic tape was applied (p<.05), while there was no significant difference in the soleus activity between no-taping and taping (p>.05). CONCLUSION: We introduce non-elastic taping as a method to decrease maximum ankle dorsiflexion and gastrocnemius activity while vertical jumping.

  • Background: Older adults use different ankle muscle activation patterns during difficult static balance conditions. It has been suggested that this is related to a decline in proprioception with age, resulting in reduced postural balance. However, the association between proprioception and ankle muscle activity during quiet standing has not been directly assessed. Objects: This study aimed to investigate the effects of age and sensory condition on ankle muscle activity and the association between ankle proprioception and ankle muscle activity. Methods: We recruited 10 young women and 9 older women. Ankle proprioception was evaluated using joint position sense (JPS) and force sense (FS) divided by dorsiflexion and plantarflexion. The electromyographic activity of the tibialis anterior (TA) and gastrocnemius (GCM) muscles was collected during quiet standing. Results: Older women activated GCM muscle more than young during quiet standing and when performing difficult tasks. Older women had more errors in JPS dorsiflexion and FS plantarflexion than did young. The GCM muscle activity is related to JPS dorsiflexion and FS plantarflexion. Conclusion: Lower proprioception of the GCM with age leads to increased muscle activity, resulting in reduced postural balance. There was no difference in TA proprioception or muscle activity among older women with frequent physical activity.
