Purpose: Our study sought to investigate differences in plantar foot pressure as a function of type of pack carried and of changing weight during gait and stance. Methods: Subjects were 40 students with no disabilities. Plantar foot pressure was measured with different types of packs carried and with changing weight of the pack during both gait and stance and while changing feet. During stance while carrying a satchel on the shoulder caused a disproportionate change in plantar foot pressure. An even great imbalance occurred for plantar foot pressure during gait. Results: Using a satchel can influence diseases such as scoliosis that are caused by unbalanced muscle activation and by a disproportionate distribution of the weight of the body. Conclusion: Knowing how to use a pack correctly and how to appropriately adjust the weight of bag should be taught.

Objectives : The purpose of this study is to find the effectiveness of Korean medical treatment on sense of balance by cerebral hemorrhage. Gaitview analysis and Berg balance scale(BBS) research were used to evaluate it. Methods : We selected patients who were hospitalized at the Kangnam Korean Hospital, Kyung Hee University Hospital from May 2014 to August 2014 that satisfied inclusion/exclusion criteria. Before taking treatment, we took gaitview analysis and BBS first to analyze the ability of balance and gait of patients. In gaitview analysis, we checked Center of gravity(COG), pressure ratio, ave pressure, gait time ratio, statistic score. For about 10 days, patients were given acupuncture treatment, herbal medicine and physical therapy. Afterwards, we compared patients' progression between before-treatment and after-treatment with the same evaluation scale. Results : In the period of treatment, patients showed static and dynamic index change within the normal range or increase. And in statistic score, 2 cases score are increased. In BBS, all cases score are increased. Conclusions : Korean medical treatment improves imbalance symptom of cerebral hemorrhage patient. So the ability of gait and activity of daily living is improved. But, this study has only 3 cases, and has no comparable study. Prospective and Larger study will be necessary.

We diagnosis two patients who have severe vertigo and gait inbalance as ‘dizziness due to retention of phlegm’ (痰暈) and gave Zexie-tang(澤瀉湯). They improved enable to walk balance and no more vetigo. Therefore we could assume that Ku-ren-xuan-mao(苦人眩冒) which is the main symptom of Zexie-tang means the vertigo and gait imbalance due to vestibular disorder.

A 70-year-old man complained imbalance while walking, inability to perform ankle flexion, and could not stand on tip-toe 3 months after injury. The ankle looked swollen with loss of Achilles contour and obvious gait disturbance. Magnetic resonance imaging shows a 5-cm Achilles tendon gap. Subsequently, surgery was performed to solve the neglected Achilles tendon rupture. Patient was put under general anesthesia with a regional block. Using a nontourniquet technique, a reconstructive procedure was performed using a half-width autologous Achilles tendon graft, which was attached to the calcaneal prominence with wire in a double strand Bunnell fashion. As for the proximal stump, double core Bunnell/modified Kessler suturing was carried out to suture the graft to Achilles stump. To increase the vascularization, an ipsilateral gastrocnemius fascial flap with a distally based-pedicle was harvested to wrap around the tendon graft. At a 6-month follow-up, the patient was able to stand on tip-toe and had also regained a normal gait.

본 논문에서는 기존의 보행 분석의 제한점을 개선한 보행분석 방법으로 보행불균형을 판단하기 위해 자체 제작한 좌 우측 고관절, 슬관절의 각도 측정 장비 및 SI 지표를 활용한 판단 시스템과 개인별 보행 상태의 양상을 분석하기 위해 DTW 유사도 분석 알고리즘을 이용한 보행 분석 방법을 제한한다. 실험은 보행 장애가 없는 총 12명의 피험자를 대상으로 정상 보행 및 불균형 보행 실험을 진행하였다. 실험결과 좌 우측 고관절과 슬관절의 각도 측정을 통한 불균형 판단 SI 지수 산출을 통해 정상 보행과 불균형 보행 모두 판단을 할 수 있었다. 개인별 보행특성 분석에서는 실험에 참여한 12명의 피험자를 대상으로 정상보행과 불균형 보행 시 허리 중앙, 좌 우측 허벅지, 발등의 측정 부위에 대한 유사도를 각각 비교하였다. 피험자별 정상 보행 및 불균형 보행 시 측정한 값에 대한 유사도 분석을 통해 보행 동작을 수행하는 동안 항시 같은 패턴의 보행 동작을 유지하는 것이 아니라는 점을 분석 결과 판단할 수 있었다.

본 연구에서는 지능형 대퇴 의족의 노면 적응 기술 구현시 보행 환경이 변화하는 구간 및 약 경사로 보행에서의 보행 불평형 문제를 해결하기 위한 방법으로 발목 관절 운동을 제어 가능한 하퇴 의족을 적용하였다. 제안한 태퇴 의족의 개발을 위해서는 보행의 단계 구분이 필수적이다. 이러한 보행의 입각기의 단계별 구분과 유각기의 판단을 위하여 대퇴의족의 슬관절 데이터와 관성센서 데이터를 바탕으로 의사 결정 나무 학습법과 랜덤포레스트 기법을 융합한 머신러닝 기술을 제안 및 적용하였다. 이러한 방법으로 발목의 운동 상태를 제어 하였으며 보행 평형이 문제가 해소 되는지를 butterfly diagram을 측정하여 평가 하였다.

Conventional gait rehabilitation requires at least three therapists in a traditional rehabilitation training program. Several robots have been developed to reduce human burden and increase rehabilitation efficacy. In this study, we present a lower-limb wearable robot (WA-H) for gait rehabilitation of hemiplegia patients, and propose a protocol of 12 weeks gait rehabilitation training program using WA-H. To identify the efficacy of the robot and protocols, we conducted a clinical study with two actual hemiplegia patients and observed a chronological change of ambulation ability through four assessments. We discovered the progression of results by 6 minute walking test, TUGT (Timed Up and Go Test), SPPB (Short Physical Performance Battery), BBS (Berg Balance Test), and Fugl-Meyer score. The torques generated in the normal side and paralyzed side of the patient became similar, indicating rehabilitation. The result also showed the walking of the paralysis patient improved and imbalance motion had considerable improved performance.

A variety of neuromuscular diseases in children cause muscle imbalance. impaired function, and resultant deformity of the lower extremities. Equinovarus, equinos, adductor contracture are common deformity of lower extremities in the children. Generally, the transfer was successful in improving or maintaining range of motion, stability of the joint and gait. Postoperative physical therapy is important. Physical therapy was instituted after cast removal. All children received stretching exercise, range of motion exercise for the joint, proprioceptive neuromuscular fascilitation and gait training was administered. This article describes our experience with the physical therapy for tendon transfered spastic cerebral palsy and discusses the therapeutic protocol.

본 연구는 이중 벨트 트레드밀을 이용하여 좌우 독립적 보행 시 횡축 체중부하 감소 유무에 따른 하지 근력불균형 개선효과에 대해 고찰하고자 한다. 피험자들은 하지의 좌우 근력차이가 20% 이상인 자 20명이며 체중부하 감소 유무에 따라 각각 10명씩 그룹으로 나누었다. 실험은 보행운동을 격일로 40분씩 주 3회, 총 4주간 진행되었으며 2주마다 등속성 관절토크 검사를 실시하여 고관절, 슬관절 및 족관절의 최대근력과 평균일률을 평가하였다. 실험 결과, 고관절에서 가장 큰 하지의 좌우 최대근력 불균형 개선효과(12.51%)를 보였으며 슬관절에서는 근반응성 개선효과(10.66%)가 크게 나타났다. 체중부하 감소방법은 하지의 근력불균형 개선효과에 긍정적인 결과를 기대할 수 있다고 사료된다.

Purpose : The purpose of this study was to investigate the effect of different heel height on the electromyographic (EMG) activity in Rectus abdominis (RA) and Erector spinae (ES) during gait activity. Methods : A repeated measures design was used. 33 healthy females carried out a standardized gait activity under 3 conditions; with heel wedges of 1, 7, and 12cm in height. EMG activity was recorded from RA and ES during the activity. Data was analysed using the repeated one-way ANOVA. Results : First, as the shoe-heel height was getting higher, change of muscle activation indicated the statistically significant difference in rectus abdominis(p<0.05). Second, as the shoe-heel height was getting higher, change of muscle activation indicated the statistically significant difference in erector spinae(p<0.05). Conclusion : We found that as heel height increased, there was an increase in EMG activity in both RA and ES. This indicated that no RA : ES imbalance was elicited. This study provides information that will inform future research on how heel height affects muscle activity around the trunk.
