Purpose : The purpose of this study was to investigate the change of the peak plantar pressure distribution under the foot areas and the range of motion (ROM) of ankle joint according to gradients in treadmill gait. Method : Thirty normal subjects (15 male and 15 female) walked on treadmill at three gradient conditions ($0^{\circ}$, $10^{\circ}$, and $15^{\circ}$) in normal speed. The ankle ROM was measured using the CMS70P that is three dimensional analyzer for excursion of ankle ROM, plantar flexion, and dorsi flexion. The peak plantar pressure distribution under the hallux, 1st metatarsal head (MTH) and heel was measured using the F -Scan system with an in-shoe sensor. Data was collected from 9 steps of left sife foot in at each gradient condition while all subjects walked. Result : As the treadmill gradient increased, the excursion of ankle joint was significantly increased (p<.05). Also, plantar flexion and dorsi flexion was significantly increased according to treadmill gradients (p<.05). The peak plantar pressure under the 1st MTH was significantly increased (p<.05) and the peak plantar pressure under the heel was significantly decreased (p<.05) as the treadmill gradient increased. No significant different in the peak plantar pressure under the hallux was observed. Conclusion : This study suggests that physical therapy for patients who have limited ankle ROM should be considered sufficient range of motion for functional ambulation. And individuals that have painful forefoot syndromes, including metatarsalgia, hallux valgus, and plantar ulceration should be careful in walking to uphill, as there is high plantar pressure under the forefoot.

The purpose of this study was to find the effects of using aid in enhancing walking ability inpatients with spinal cord injury who have received rehabilitative care. The study population consisted of 24 spinal cord injury patients referred to the Department of Rehabilitation Medicine in the National Rehabilitation Center (NRC). All subjects were ambulatory with or without an assistive devices. All of the participants were assessed on SCIM II, WISCI II, FIM, MBI, gait speed (m/s), and walking endurance (120 min/m). The data were analyzed using a paired t-test, a one-way ANOVA, and a Duncan test. The results revealed that TSCIM II and all of the items of SCIM II of the cervical ASIA D group patients were higher than those of the Thoracic ASIA A and C group patients (p<.05). The FIM, MBI, and WISCI II of the cervical ASIA D group patients were higher than those of the Thoracic ASIA C group patients (p>.05). The walking velocities of the lumbar ASIA C group patients were higher than those of Thoracic ASIA A group patients (p<.05). The walking endurance of the lumbar ASIA C group patients was higher than that of the thoracic ASIA C group patients (p<.05). The ASIA D group patients used bilateral standard canes or crutches, but none used AFO. The ASIA A and C group patients used bilateral standard walkers with KAFO for standing and walking. The findings suggest that injury level as well as the functionality of walking aids should be considered when formulating a rehabilitative plan for patients with spinal cord injury.

Background : To estimate fall incidence rate and associated factors in inpatients from a general hospital. Method : The data were collected from 104 fall incident reports developed by the patient safety committee in a general hospital in Seoul from 01 January 2007 to 31 December 2008. Information included general characteristics of patients, factors related to fall, types, places, circumstances and outcomes of fall. Result : The incidence rate of fall, which was 4.4 per 1,000 total discharged patients and 0.5 per 1,000 patient-days, was much lower than that of several hospitals in the United States. The difference may reflect the different incidence reporting system of each hospital. Fall-prone patients were, in general, $$\geq_-$$65 years of age, had an alert mental status, were ambulatory with some assistance, and were dependent on and ambulatory device. High incidence of falls was associated with patients with circulatory disease. The majority of fall events usually occurred in bed or at the bedside in the patient's room, and occurred more often during the night than during the day or evening. Risk factors of fall were use of drugs (antihypertensive or neuropsychiatric drugs) and environmental factors (e.g., overly high bed height, surrounding objects, inadequate fitness shoes and slippery floor). Physical injury occurred in 43.3% of fall events, which typically required diagnosis of injury and treatment such as suturing. Risk factors for repeated falls were use of a neuropsychiatric drug (odds ratio=13.9) and gait disturbance (odds ratio=91.2). Risk factors for fall-related injury were alert mental status (odds ratio=3.3 times more likely to fall than those who were drowsy or in a stupor) and general weakness(odds ratio=3.3 times more likely to fall than those who were not generally weak). Conclusion : Medical and nursing staff should be aware of the fall risk factors of hospitalized patients and should intensively pursue preventative strategies. Development of fall prevention education based on these results is recommended.

본 논문은 다양한 지면에 적응 가능한 견형 4족 로봇의 위치 이동에 관한 것으로 정 보행과 동 보행의 구현 방법 및 특성을 주로 다루었다. 이를 위하여, 총 12 자유도의 로봇을 자체 제작하였으며, 몸통과 발의 운동궤적을 생체 모방 방식으로 생성한 후 역기구학에 의하여 그에 해당하는 각 다리의 관절각을 해석적으로 구하였다. 이러한 관절각 데이터를 상기 로봇의 ADAMS 모델에 적용하여 컴퓨터 시뮬레이션을 수행한 결과, 계획된 걷기 및 속보 걸음새가 동력학적으로 안정함을 확인하였다. 그러나 그 이전의 속보 패턴의 경우에는 시뮬레이션 결과와는 달리 실험 중 불안정한 거동을 보였다. 그에 따라 원인 분석을 하는 과정 중, 속보와 같은 동 보행의 경우 ZMP보다는 WSM의 개념을 적극적으로 활용하고 보행 주기를 최대한 단축시키는 것이 안정성 확보에 매우 중요함을 발견하였다.

Objective: The purpose of this study was to investigate the relationship between anticipatory postural adjustment (APA), single task, dual tasks and physical performances. The trunk muscles of APA consist of bilateral erector spinae (ES) and bilateral internal oblique (IO) adnominal muscles, during rapid stepping with the affected or unaffected leg in a sitting posture. Design: Cross-sectional study. Methods: In patients with chronic stroke, electrodes of surface electromyography (EMG) were attached on the bilateral erector spinae (ES), bilateral internal oblique adnominal (IO), and bilateral rectus femoris (RF) muscles. RF acts as the prime mover. The stroke patients performed hip flexion until $20^{\circ}$ as fast as possible at each leg in a sitting posture according to a visual cue. The visual cue unexpectedly appeared on monitor in front of the stroke patient. The single task was the Timed Up and Go (TUG) test. The dual tasks were the TUGconitive, which increased cognitive capacity, and the TUGmanual task, which had an external focus. Results: All EMG data showed earlier onset latency before the prime mover. In affected leg raising, the onset time of unaffected ES muscle of the stroke patients was correlated with the single and dual tasks (p<0.05). In unaffected leg raising, the onset time of the affected IO muscle was related to all the tasks (p<0.05). Gait speed showed a relationship with the unaffected ES muscle only. Conclusions: The trunk muscles of the bilateral ES and bilateral IO play an important role in APA. The single and dual tasks using TUG test were correlated with the APA s of ES and IO muscles. Dual task by the TUG test is a good measuring tool for reflecting the real life in patients with chronic stroke.

Purpose: This study was conducted to determine the structural change in knees caused by quadriceps angle and the muscle activity in lower limbs. Indirect intervention was provided by using taping for stability in the ankle joints, which affected patellofemoral pain. Methods: The subjects in this study were 20 patients with patellofemoral pain who visited ${\bigcirc}{\bigcirc}{\bigcirc} $ Hospital in Busan. The visual analogue scale measured the dynamic quadriceps angle and the degree of pain felt by the patients while walking down stairs, which was a known factor of patellofemoral pain. In addition, muscle activities in the rectus femoris, vastus lateralis, vastus medialis, tibialis anterior, peroneus longus, and biceps femoris, which affect the knees and ankles, were measured using surface electromyography. The muscle activities were converted into %RVC for this study. The data obtained in this study were analyzed with the Wilcoxon signed-rank test using the SPSS Ver. 25.0 statistical program. The significance level ${\alpha}$ was 0.05. Results: The study results showed that the pain and dynamic quadriceps angle were significantly reduced statistically when applying the calcaneus fixation taping (p<0.05). Muscle activity in the lower limbs was significantly decreased in the vastus medialis, vastus lateralis, and tibialis anterior (p<0.05). Conclusion: The summary of the study results verified that the calcaneus fixation taping reduced the pain and dynamic quadriceps angle by providing stability in the ankle joints. It also produced efficient movement due to the difference in lower-limb muscle activity.

뇌졸중 질환은 전세계적으로 가장 중요한 사망원인 중 하나이며, 특히 고령자에게 장애의 원인이 되는 가장 중요한 질환이다. 뇌졸중 질환이 발생하면 사망 또는 심각한 장애를 유발하기 때문에, 적극적인 일차 예방과 전조증상의 빠른 발견이 매우 중요하다. 특히, 일상생활에서의 뇌졸중 전조증상 발병을 감지 및 정확히 예측하여 전문가의 신속한 진단을 유도할 수 있어야 한다. 최근까지의 연구에서는 뇌졸중 환자의 전조증상을 예측하는 방법론으로 CT(Computed Tomography)나 MRI(Magnetic Resonance Imaging)와 같은 영상 분석이 대부분이었으나, 이러한 접근에는 오랜 검사 시간과 높은 검사 비용 등에 대한 한계점을 가지고 있다. 본 논문에서는 고령자의 뇌졸중 질환 발병이 보행 시 족압(Foot Pressure)에 어떤 영향을 미치는지 임상 데이터를 이용해 실험하였다. 실험 결과, 보행 중에 뇌졸중 고령자와 일반 고령자 간에 12개의 셀에서 * p < .05 인 유의미한 차가 있음을 분석 및 검증하였다. 결과적으로 고령의 뇌졸중 환자와 일반 고령자의 일상생활의 보행 패턴에 유의미한 차이를 발견했다는 것에 그 의미가 크다고 할 수 있다.
