Background: Ankle sprains are a common clinical ankle disorder and alternations in tibiofibular joint biomechanics along with the talus are thought to contribute to its occurrence. During ankle joint dorsi flexion, proper movement requires the talus to glide posteriorly. Due to the wider front of the talus head, achieving the end range of dorsi flexion necessitates both superior and posterior glide of the distal fibula and anterior glide of the proximal fibula. The purpose of this study was to investigate the effects of tibiofibular joint mobilization on pain, range of motion, and balance in patients with lateral ankle sprains. Methods: Participants were randomly assigned to a control group (n=33) or an experimental group (n=31). Both groups underwent ankle joint mobilization three times a week for two weeks. Additionally, the experimental group received proximal and distal tibiofibular joint mobilization three times a week for two weeks. Measurements were obtained pre-intervention and post-intervention (after 2 weeks). Results: Evaluation parameters included the visual analog scale score (VAS), range of motion (ROM), and one-leg standing test (OLS). Post-intervention, both groups demonstrated significantly improved results for all assessments (p<.01). A significant intergroup difference was observed only in the ROM (p<.01) and OLS (p<.05). Conclusion: Our findings suggest that tibiofibular joint mobilization, combined with ankle joint mobilization, may be beneficial in enhancing outcomes for individuals with lateral ankle sprains.

The purpose of the study was to compare the differences among phases accoring to the gait time on the heel height during gait, investigate the effect on ROM of the lower limb on gait time. Ten female college students in their 20s participated in the study, and variables were calculated through 3D gait analysis on height of heel. As a statistical method, one-way ANOVA was performed for the differences between the three heel heights, and multiple regression analysis was performed to determine the effect of gait time on the ROM. As a result of the study, phase 2, the higher the heel, the longer the gait time, but phase 3, the higher the heel, the shorter the gait time. As a result of analyzing the effect of gait time on the ROM of the lower limb, in phase 2, the greater the ROM for the ankle and knee joint in 1 cm, and for the ankle joint in 5 cm, the longer the gait time. In phase 3, the greater the ROM for the hip joint in 1 cm, the longer the gait time, and the smaller the ROM for the ankle joint in 10 cm, the longer the gait time. Therefore, in the case of high-heeled shoes, it is suggested that the control of the ankle joint is important.

Objectives: The purpose of this study is to evaluate the clinical effects of Muscle Energy Technique (MET) for peroneal nerve palsy after normal delivery. Methods: Two patients with peroneal nerve palsy were treated with acupuncture, moxibustion, cupping and MET. MET was performed in piriform, gluteus medius, anterior tibial and adductor muscles. To evaluate the effect of MET, we analyzed Ankle dorsiflexion range of motion (ROM), Manual Muscle Test (MMT), Numerical Rating Scale (NRS) and Ankle Hindfoot Scale (AHS). Results: In Case 1, ROM score was changed from −5 to 20, and MMT score was changed from 0 to 4. NRS score was changed from 5 to 1, and her AHS score was changed from 54 to 94 after treatment. In Case 2, ROM score was changed from 0 to 20, and her MMT score was changed from 1 to 5. NRS score was changed from 4 to 1, and her AHS score was changed from 64 to 97 after treatment. Conclusions: MET may be a useful treatment for patients who, shortly after childbirth or while breastfeeding, strongly refuse to treat the irritation.

The purpose of this study was to analyse the effect of the drop height on lower extremity and lower back kinematics and kinetics during drop landing with the use of raised heel insole. Furthermore we investigated the change that occurred in our body. Joint ROM, eccentric work and contribution to total work were calculated in 11 male college students performing drop landing with 8 motion analysis cameras and 1 forceplate. The result were as follows. First, the ROM and eccentric work were increased in all joints with the increase of the drop height. Second, the ankle ROM and eccentric work were decreased with the use of the insole. Third, the use of the lower back was increased as the use of the ankle decreased with the insole. Based on these results, we can infer that putting on the insole may contribute to chronic injury. We recommend not to use the insole during physical activity.

Objective: The purpose of this study was to examined the kinematic relationship and differences through the range of motion (ROM), muscle activity, and vertical ground reaction force (VGRF) during forward and backward lunge movements, which are effective in improving muscle strength and balance ability of the lower extremities, and to provide clinical information on more efficient lunge movements. Design: Cross-sectional study Methods: Fifteen adult males who met the selection criteria were tested for their dominant feet.Forward and backward lunges were then performed, and the ROM, muscle activity, and VGRF were measured for kinematic analysis during the lunge movement.The differences betweenthe forward lunge and backward lunge intervention were examined using a paired t-test. Results: A significant increase in the ROM of the knee and ankle was observed during the forward and backward lunges (p<0.05). In addition, in terms of the muscle activity, the peak values of the vastus medialis oblique (VMO) and VGRF also showed a significant increase in the forward lunge compared to the backward lunge (p<0.05). Conclusions: This study showed an increase in VGRF peak value, knee and ankle ROM, and VMO muscle activity during forward lunge. Based on these results, it is considered necessary to apply differently depending on the direction of progress in consideration of the musculoskeletal situation and physical ability during the lunge movement.

PURPOSE: The purpose of this study is to determine the effect of therapeutic exercise on pain, range of motion and strength, and balance ability in a patient with an anterior ankle impingement (AAI). METHODS: A-32-year-old male presented limited ankle motion and pain with forced dorsiflexion at both ankle joints. In response, a therapeutic exercise program consisted of ankle joint mobilization, strength exercises using an elastic band, and proprioceptive exercises including semi-squats and a one-legged standing exercise with open and closed eyes. The program was performed for 40 min/day, twice per week, for 8 weeks. Pain, range of motion (ROM), and muscle strength (ankle dorsiflexion, plantarflexion, inversion, and eversion), as well as a one-legged standing test of both ankles, were measured before and after 4 and 8 weeks of therapeutic exercise. RESULTS: VAS decreased in both ankles after 8 weeks of exercise, respectively, compared to baseline levels. Range of motion and strength increased in both ankles for dorsiflexion, plantarflexion, inversion, and eversion after 8 weeks of exercise compared to baseline levels. In addition, the ability to perform a one-legged standing test with eyes opened and closed improved in both legs after 8 week of exercise compared to baseline levels. CONCLUSION: These results suggest that therapeutic exercise improves pain, ROM, muscle strength, and balancing ability in patients with AAI.

The purpose of this study is to develop a minimally constraint joint angle measurement system for the feedback control of FES (functional electrical stimulation) locomotion. Feedback control is desirable for the efficient FES locomotion, however, the simple on-off control schemes are mainly used in clinic because the currently available angle measurement systems are heavily constraint or cosmetically poor. We designed a new angle measurement system consisting of a magnet and magnetic sensors located below and above the ankle joint, respectively, in the rear side of ipsilateral leg. Two magnetic sensors are arranged so that the sensing axes are perpendicular each other. Multiple positions of sensors attachment on the shank part of the ankle joint model and also human ankle joint were selected and the accuracy of the measured angle at each position was investigated. The reference ankle joint angle was measured by potentiometer and motion capture system. The ankle joint angle was determined from the fitting curve of the reference angle and magnetic flux density relationship. The errors of the measured angle were calculated at each sensor position for the ankle range of motion (ROM) $-20{\sim}15$ degrees (dorsiflexion as positive) which covers the ankle ROM of both stroke patients and normal subjects during locomotion. The error was the smallest with the sensor at the position 1 which was the nearest position to the ankle joint. In case of human experiment, the RMS (root mean square) errors were $0.51{\pm}1.78(0.31{\sim}0.64)$ degrees and the maximum errors were $1.19{\pm}0.46(0.68{\sim}1.58)$ degrees. The proposed system is less constraint and cosmetically better than the existing angle measurement system because the wires are not needed.

The multiple acupuncture techniques have been used to relieve the pain of lateral ankle sprain. Recently, early functional rehabilitation is emphasized in rehabilitative concepts using active ROM, facilitated proprioception, alphabet exercise and so forth. Similarly, in oriental rehabilition medicine, traditional movement technique called 'Dong-Ki' has been used to relieve pain of ankle sprain. So we used 'Dong-Ki' technique with SSP(silver spike point) electrotherapy transformed from alphabet exercise and evaluated the effects in method of randomized controlled trials. 27 outpatients with lateral ankle sprains were randomized into two groups : 15 samples and 12 controls. Sample group was treated with 'Dong-Ki' technique(writing his name with foot) with SSP electrotherapy to relieve pain during additionally. 'Dong-Ki'. Outcomes were measured by 10cm VAS and ankle circumference(cm). In terms of VAS, Sample group had inclination of pain relieving but not significantly meaningful. In terms of ankle circumference measurement, Sample group showed significantly improved.

Purpose: The purpose of this study was to investigate the kinematic characteristics and muscle activities during the following two conditions: transition from half-kneel to standing on the affected leg and non-affected leg. Methods: Twenty-one hemiplegic patients participated in the study. A motion analysis system was used to record the range of motion and angle velocity of the hip, knee and ankle from the half-kneel to the standing position. Electromyography was used to record the activity of 4 muscles. Results: The statistical analysis showed that the minimum ROM of the hip joint was less on the affected leg during transition from half-kneel to standing. However, the minimum ROM of the knee and ankle joints was less on the non-affected leg during transition from half-kneel to standing. The angle velocity of the knee and ankle joints was less during transition from half kneeling to standing on the non-affected leg. Muscle activity of the rectus femoris and tibialis anterior was less while moving from half-kneel to the standing position on the affected leg. Conclusion: These results show that greater active ROM of the knee and ankle was required on the affected leg for transition from half-kneel to the standing position than for normal gait. Muscle activity of the rectus femoris and tibialis anterior is normally required for movement from the half-kneel to the standing position during normal gait. Further studies are needed to investigate the antigravity movement in healthy subjects and hemiplegic patients in order to completely understand the normal and abnormal movement from the half-kneel to the standing position.
