PURPOSE: The purpose of this study was to investigate the effect of functional training using a sliding rehabilitation machine (SRM) on the mobility of the ankle joint and balance in children with cerebral palsy (CP). METHODS: The subjects consisted of 11 children who were diagnosed with spastic CP. They carried out the functional training using the SRM for 30 minutes, three times a week, for 8 weeks. Before and after all of the training sessions, the subjects were tested using the Pediatric Balance Scale (PBS) and Gross Motor Function Measurement (GMFM), range of motion (ROM) in the ankle joint, the pennation angle of the gastrocnemius muscle and the fascicle length of gastrocnemius muscle were measured to determine the mobility of the ankle joint and balance ability. RESULTS: There were significant differences between the pre-test and post-test in the PBS and GMFM. The ROM of the ankle joint was significantly increased after the functional training using the SRM. Moreover, the fascicle length was increased and the pennation angle was decreased after the functional training using the SRM, but the difference was not significant. CONCLUSION: These results suggest that functional training using the SRM may have some effect on the mobility of ankle joint and balance in children with CP. According to the results, this study could present an approach to the rehabilitation or treatment of children with CP.

PURPOSE: This study was conducted to investigate the effects of combined Joint Mobilization and Functional Electrical Stimulation on Muscle Activation and Mobility of ankle joints in stroke patients and their Modified Functional Reach Test (MFRT) results. METHODS: A total of 26 patients with stroke were randomly selected for enrollment in this study. (1) Functional Electrical Stimulation (FES) (2) combined Joint Mobilization and FES. An EMG system was used to measure tibialis anterior and gastrocnemius activities. Range Of Motion (ROM) of Ankle Joint and MFRT for Dynamic Balance. Pre and post intervention results were compared by paired-t-tests and differences in changes after intervention between groups were identified by the independent t-test. RESULTS: The muscle activation, ROM, and MFRT differed significantly in the experimental group (p<.05). The ROM was significantly different for the active dorsiflexion pre and post intervention in the group that received FES alone (p<.05). CONCLUSION: The results of this study suggest use of a systematic program of proactive posture control to prevent dysfunction when planning interventions for ankle joints can help stroke patients walk efficiently.

Background: The purpose of this study was to compare the differences in gait and mobility according to the types of assistive device for ankle joint including ankle foot orthosis (AFO), non-elastic tape, elastic tape, and high ankle shoes in chronic hemiplegic stroke survivors. Design: A cross-over design. Methods: Twelve hemiplegic stroke survivors participated in this study, and they walked under 5 different conditions including bare feet, wearing a AFO, wearing a non-elastic tape, wearing a elastic tape, and wearing a high ankle shoes. During the participants walked, the spatio-temporal gait analysis and mobility examinations were performed. For the spatio-temporal gait analysis (gait velocity and cadence, step length, stride length, and single and double leg support time) and mobility examinations, the gait mat, TUG and TUDS were used. Results: As s results, on the AFO, non-elastic tape, elastic tape, and high ankle shoes, there were significantly differences in the all spatio-temporal gait parameters, TUG, and TUDS compared to barefoot (p<0.05). In particular, all spatio-temporal gait parameters, TUG, TUDS were significantly improved with AFO compared to barefoot. TUG was significantly improved with AFO compared to non-elastic tape, TUG and TUDS were significantly improved with AFO compared to elastic tape, gait velocity was significantly improved with non-elastic tape compared to high ankle shoes, gait velocity and TUG were significantly improved with elastic tape compared to high ankle shoes, and TUDS was significantly improved with non-elastic tape compared to elastic tape. Conclusion: The AFO, non-elastic tape, elastic tape, and high ankle shoes showed a positive effect on gait and mobility compared to barefoot, and among them, wearing AFO was most effective for improving gait and mobility of chronic hemiplegic stroke survivors.

PURPOSE: Stroke patients have reduced balance ability due to a lack of motion in the ankle joint. Elastic taping assists movement, and joint mobilization, a form of passive movement, enhances mobility. The purpose of this study was to determine the immediate effects on balance ability after anterior-to-posterior (A-P) talocrural joint mobilization combined with elastic taping in stroke patients. METHODS: Twenty stroke patients were divided into two groups: a joint mobilization with taping group (experimental group, n=10) and an elastic taping only group (control group, n=10). The experimental group underwent anteroposterior mobilization of the talus and elastic tape was applied to the calf and tibialis anterior muscles. The control group had elastic tape applied. Dynamic balanced abilities were assessed by using the BioRescue system. After 30 minutes of intervention, the forward, backward, left side, and right side sway areas ($mm^2$) were measured. RESULTS: Only the experimental group showed a significant increase in forward sway area after intervention. However, no significant differences were detected between the two groups. CONCLUSION: This study shows that A-P talocrural joint mobilization combined with elastic taping has a positive effect, producing an immediate increase in the forward balance ability of stroke patients. However, this study did not examine joint mobilization alone. In subsequent studies, it is necessary to examine the effect of joint mobilization only on balance in stroke patients.

Objective: The purpose of this study was to investigate the effects of a 12-week combined exercise program on gait parameters in elderly women with osteoarthritis. Method: The subjects of this study were 11 elderly women (age: $67.09{\pm}2.47$, height: $157.35{\pm}4.30cm$, weight: $62.49{\pm}6.36kg$) with knee osteoarthritis. The combined exercise program of this study was divided into aerobic exercise and lower extremity strengthening exercises. The exercises were performed for 60 minutes per session, three times a week, for a total of 12 weeks. The maximum joint moments of the hip, knee, and ankle joints with walking were obtained with 8-3D cameras (MX-T20, Vicon, USA) and 2-force plate (AMTI OR6-7-400, AMTI, USA). SPSS Windows version 23.0 was used for statistical analysis. A paired t-test was used for pre-post comparison. An alpha level of .05 was utilized in all tests. Results: The maximum extension moment was significantly higher in the hip joint after P1 on the X axis. The maximum joint moment of P3 in extension was statistically significantly lower after intervention. On the Z axis, the maximum joint moment was significantly lower after the exercise intervention at P3. There was a statistically significant increase in the extension moment of the left and right knee joints in the X axis after exercise intervention. In the right ankle joint, P1 (plantar flexion moment) showed a statistically significant high moment after exercise intervention. Conclusion: These results suggest that combined exercise, including lower limb and aerobic exercise, may have a positive effect on mobility and walking moments in patients with osteoarthritis of the knee.

The use of AFO in the management of patients with hemiplegia has been somewhat controversial. The purpose of the study was to identify the influence of the plastic ankle foot orthoses(AFO) on the characteristics of pelvic tilt in the patients with hemiplegia. Sixteen hemiplegic patients participated. The angle of pelvic tilt were measured using the BROM II . Results showed that the hemiplegia who weared plastic AFO, the angle of pelvic tilt was significantly less than not weared subjects. However. duration of wearing a plastic AFO and the degree of spasticity were not affected to the angle of pelvic tilt. Therefore the patients with hemiplegia should consider using the brace for the right purpose, also need to maintain the mobility of ankle joint while wearing the plastic AFO.

Soft-tissue deficits over the plantar forefoot, plantar heel, Achilles tendon, and distal parts of lower leg are often troublesome to cover with a simple graft or local flap due to limited mobility of surrounding skin and poor circulation in these area. Soft-tissue reconstruction in these regions should provide tissue components similar to the original lost tissue, supply durability and minimal protective pressure sensation and result in a donor site that is well tolerated and treated. We analysed 7 cases that were treated with the Instep flap due to soft-tissue defects over these regions from July of 1990 to July of 1993. All flaps were viable and successful at follow-up. 1. The age ranged from 9 years to 60 years, and 6 cases were male and 1 case female. 2. The sites of soft-tissue loss were the plantar forefoot(1 case), plantar heel(3 cases), Achilles tendon(2 cases), and distal parts of lower leg(1 case). 3. The causes of soft-tissue loss were simple soft-tissue crushing injury(1 case), crushing injury of the 1st toe(1 case) and posttraumatic infection and necrosis(5 cases). 4. The associated injury were open distal tibio-fibula, fracture(2 cases), medial malleolar fracture of the ankle(1 case), Achilles tendon rupture(2 case) and 1st metatarso-phalangeal disarticulation(1 case). 5. The size of flap was from $3{\times}4cm$ to $5{\times}10cm$(average $4{\times}5.6cm)$. 6. In 7 cases, we were not to find post-operative necrosis and infection, non-viability, limitation of ankle joint, and gait disturbance caused by the Instep flap surgery. 7. This study demonstrates that the Instep flap should be considered as another valuable technique in reconstruction of these regions.
