Objectives: Neurological examination on balance function is widely applied in clinical practice. Balance function may be clinically relevant to an assessment of yinyang balance in such therapies as temporomandibular joint balancing medicine. Fukuda stepping test is a relatively not-well-known method of balance function test. This study reviewed the procedures and criteria of Fukuda stepping test. Method: Recent articles on Fukuda stepping test were searched in public database (Pubmed, Proquest) and reviewed for its procedures and clinical implications. Results: Fukuda stepping test adopts 50 steps or 100 steps with subsequent assessment of the deviation or displacement of the subject. It may not be reliable during acute phase. Conclusion: Fukuda stepping test may be utilized and be further developed to assess balance function in the neurological management of functions.

Purpose: Trunk muscle weakness in the children with cerebral palsy can lead to postural and alignment problems, breathing difficulties, and so on. Therefore, children with cerebral palsy can benefit from exercises that strengthen the muscles in their trunks. The purpose of this study was to investigate the effects of trunk muscle strengthening exercise on functional gross movement and balance ability in children with spastic diplegic cerebral palsy. Methods: We used single group repeated measure design in 8 children(four males, four females; aged 6~12 years; mean 8.3 years) with diplegia. The functional gross motor outcome measured by using the GMFM and balance ability of all children was measured by pediatric balance scale. All participants were alternately received trunk strengthening exercise and neurodevelopment treatment for 40 minutes twice per week during 8 weeks. Results: Significant and clinical meaningful improvement in functional gross motor and balance ability were shown. Conclusion: The results indicate that trunk strengthening exercise has a positive effect on both functional gross motor and balance ability in children with spastic diaplegic cerebral palsy.

The purpose of this study was to determine differences of balance performance to upright standing, forward bending posture, and sudden load during forward bending posture in subjects with and without a history of low back pain. A study was conducted on 8 subjects with low back pain and 13 healthy subjects. Dynamic Balance System was used to measure the postural sway index, left-right sway index, and anterior-posterior sway index on balance performance. There were no differences between subject groups on balance performance during upright standing. Balance performance was increased in forward bending posture and decreased in sudden load during forward bending posture in subjects with low back pain. These results suggest that subjects with low back pain demonstrated increased activity and decreased reaction times of trunk muscles.

Background: Functional ankle instability (FAI) indicating a decrease in muscle strength, proprioception, neuromuscular control, balance and postural control function. Objective: To investigate the effect of jumping exercise on the supporting surface on the ankle muscle thickness, proprioceptive sensation, and balance in adults with FAI. Design: Randomized Controlled Trial. Methods: Twenty young people with FAI were randomly assigned to the unstable supporting surface jump group (N=10) and the stable supporting surface jump group (N=10). The intervention was conducted three times a week for eight weeks, and for 30 minutes per session. Trampoline was used as an unstable support surface and the stable support surface was carried out on a regular floor. The thickness of the tibialis anterior muscle and medial gastrocnemius muscle was measured by ultrasonography, and the proprioception of dorsiflexion and plantarflexion was measured using an electrogoniometer. The dynamic balance was also measured with a balance meter. Results: The the muscle thickness of the medial gastrocnemius muscle was significantly higher in the stable supporting surface jump group than in the unstable supporting surface jump group (p<.05). Furthermore, the plantar flexion proprioception and dynamic balance were significantly improved in the unstable supporting surface jump group than in the stable supporting surface jump group in the intergroup comparison (p<.05). Conclusions: The conclusion has been reached in this study that the jumping exercise on the unstable supporting surface could be a more effective in improving FAI than the regular surface.

Purpose: Temporomandibular disorder (TMD) is a condition defined as pain and dysfunction of temporomandibular joints and masticatory muscles. Abnormal interconnections between temporomandibular muscles and cervical spine structures can cause the changes of postural alignment and balance ability. The aim of this study was to investigate changes in static balance ability in subjects with painrelated TMD. Methods: This study conducted on 25 subjects with TMD and 25 control subjects with no TMD. Pressure pain thresholds (PPTs) of the masseter and temporalis muscles were measured using a pressure algometer. Static balance ability was assessed during one leg standing using an Inertial Measurement Unit (IMU) sensor. During balance task, the IMU sensors measured motion and transfer movement data for center of mass (COM) motion, ankle sway and hip sway. Results: PPTs of masseter and temporalis muscles were significantly lower in the TMD group than in the control group (p<0.05). One leg standing, hip sway, and COM sway results were significantly greater in the TMD group (p<0.05), but ankle sways were not different between group. Conclusion: We suggest pain-related TMD is positively related to reduced PPTs of masticatory muscles and to static balance ability. These results should be considered together with global body posture when evaluating or treating pain-related TMD.

Objective: This study investigated the effect of a video game-based home exercise program on the improvement of balance and muscle strength in the elderly. Design: Randomized controlled trial Methods: Participants were randomly assigned to two groups: a video game-based home exercise training group (experimental group, n=16) and a control group (n=17). The experimental group trained three times a week for 50 minutes per session for six weeks, and the control group did not perform any exercise. To evaluate postural balance, one leg standing test, Berg balance scale, functional reach test, and timed up and go test were performed, and five times sit-to-stand was performed to evaluate lower extremity muscle strength. Results: In the experimental group, there were statistically significant improvements (p<0.05) in one leg standing test, Berg balance scale, functional reach test, and timed up and go test, and five times sit-to-stand after the intervention, but in the control group, the difference before and after the intervention was not significant. The difference between the groups according to the experimental method showed a significant increase in the experimental group (p<0.05). Conclusions: These results suggest that a video game-based home exercise program effectively improves balance and muscle strength in the elderly. A video game-based exercise program can contribute to the rehabilitation of the elderly as a method of home remote rehabilitation.

본 연구는 여자대학 체조선수 3명을 대상으로 평균대의 좌측 턴 동작 시 성공과 실패에 따른 동적 자세조절에 미치는 신체중심(C.O.G) 변화와 안구 움직임(E.O.G)의 관계를 분석하는데 목적이 있다. 성공 시 몸통이 $180^{\circ}$ 회전하는 시점까지 C.O.G는 회전방향으로 이동되는 경향이었으며, 실패 시에도 동일한 경향이 나타났지만 C.O.G의 편차가 상대적으로 큰 이동을 보여 동적 자세 조절 유지에 영향을 미치는 특징이 있었다. 회전 동작 시 E.O.G는 몸통의 회전 방향과 안구가 반대로 이동한다는 사전 이론과 일치하였지만 중심이동 시점에서는 차이가 있었으며 동작의 성패에서는 확연한 차이가 나타났다. 또한 실패 시 상-하 E.O.G는 대부분이 하 방향으로 작용하는 특성을 나타내고 있어서 실패의 원인과의 연관성을 분석할 필요를 느꼈다. 따라서 평균대 턴 동작에서 동적 자세 조절능력과 E.O.G의 운동역학적인 후속연구가 심층적으로 수행된다면 미세한 원인을 규명할 수 있을 것으로 사료된다.

PURPOSE: This study examined the effects of a whole body vibration-exercise program on the muscle strength, balance, and falling efficacy of super-aged women. METHODS: Thirty participants, who are over 75 years of age, were recruited. They were assigned randomly to an experimental group (n=15), which received whole body vibration exercise, and a control group (n=15), which received an exercise program that did not include vibration. The interventions lasted for four weeks, three times a day, and 25 minutes per session. To compare the effects of the intervention, a 30-second chair stand test (CST), Korean version of Berg balance scale (K-BBS), functional reach test (FRT), timed up and go test (TUG), and Korean version of the falls efficacy scale (K-FES) was used. RESULTS: The experimental group showed a significant increase (p.<05) before and after the intervention in the chair stand test (CST), Korean version of the Berg balance scale (K-BBS), functional reach test (FRT), timed up-and-go (TUG), and Korean version of the fall efficacy scale (K-FES). Compared to the control group, the experiment group showed a more significant increase (p.<05) in the CST, K-BBS, and FRT. CONCLUSION: A whole body vibration exercise program could be suggested as an effective intervention method for muscle and balance strengthening for super-aged women.

Purpose: This study was to investigate the effects of unilateral muscle fatigue in knee and ankle joints on balance and gait in healthy adults. Methods: Exercise inducing muscle fatigue in the knee joint consisted of concentric and eccentric contraction of dominant knee extensors in healthy adults by using the Leg Extension Rehap exercise machine (HUR, Finland). Exercise inducing muscle fatigue in the ankle joint was composed of voluntary contractions and forced contractions of the dominant plantar flexors in healthy adults. Exercises to induce muscle fatigue in the knee and ankle joints were performed until the subject complained of fatigue or pain, the occurrence of muscle fatigue was confirmed by electromyography. We measured static and dynamic balance using the Good Balance system and gait performance by RS-scan. Results: Static and dynamic balance ability and spatial-temporal gait decreased significantly after muscle fatigue in knee and ankle joint. Conclusion: These results show that unilateral muscle fatigue of the lower extremities affected postural control and gait. Therefore, therapists and sport trainers should minimize the risks of fall and injuries related to unilateral muscle fatigue.
