본 연구의 목적은 넘어짐 예방 운동이 여성노인의 체력, 자세, 낙상효능감에 미치는 영향을 규명하는 것이다. 연구 대상은 65세 이상의 여성노인 30명을 대상으로 하였으며, 그 중 14명은 운동집단, 16명은 비교 집단으로 하였다. 넘어짐 예방운동 프로그램은 탄성밴드를 이용한 다방향 근력 근지구력, 파워 운동, 자세 정렬 운동과 한국무용 동작을 접목한 다방향 동적균형, 협응력 운동으로 구분하였고 총 12주간, 주 2회, 각 60분으로 진행하였다. 운동 프로그램 전후의 체력, 자세, 낙상 효능감을 측정하여 비교하였다. 연구 결과 운동 집단은 악력을 제외한 근지구력, 심폐지구력, 유연성, 평형성, 협응력에서 유의하게 증가하였고, 자세는 상체 기울기를 제외한 어깨 기울기, 견갑골 기울기, 골반 기울기, 종골각 기울기, 다리길이 차이가 유의하게 감소하였다. 낙상 효능감 점수는 운동 집단에서는 증가하고 비교 집단에서 감소하였으나, 모두 통계적으로 유의하지는 않았다. 그러므로 넘어짐 예방운동은 체력 향상과 자세교정에 효과적이라는 결론을 내릴 수 있다. 그러나 악력(근력)을 증가하는 것과 상체기울기를 교정하는 운동프로그램의 보완이 필요하다.

Weight bearing training on the involved leg is impotant for ambulation and activities of daily living in ambulatory hemiplegic patients. Traditionally, physical therapists have relied on exercise therapy and subjective evaluation. The goal for this study was to measure lower extremity weight distribution in standing with ten hemiplegic pations(M:8, F:2) and to determine the traing effect on symmetrical standing posture using a "Limloader". The Limloader is a machine designed for training symmetrical weight bearing posture. The results showed that the ability to keep the center of gravity within the limits for balance was improved significantly but the ability to adjust weight bearing on the involved leg was not (p<0.05). This study demostrated that hemiplegics can improved their symmetrical weight bearing ability using sensory biofeedback.

This paper proposes an evolutionary optimization approach for optimal hopping of humanoid robots. In the proposed approach, the hopping trajectory is generated by a central pattern generator (CPG). The CPG is one of the biologically inspired approaches, and it generates rhythmic signals by using neural oscillators. During the hopping motion, the disturbance caused by the ground reaction forces is compensated for by utilizing the sensory feedback in the CPG. Posture control is essential for a stable hopping motion. A posture controller is utilized to maintain the balance of the humanoid robot while hopping. In addition, a compliance controller using a virtual spring-damper model is applied for stable landing. For optimal hopping, the optimization of the hopping motion is formulated as a minimization problem with equality constraints. To solve this problem, two-phase evolutionary programming is employed. The proposed approach is verified through computer simulations using a simulated model of the small-sized humanoid robot platform DARwIn-OP.

The purpose of this study is to understand the structure and biomechanics of the skeletal muscle. The skeletal muscle takes 40 to 45% of the whole body. Stable posture requires a balance of muscle. However, when the muscle strength is unbalanced, movement initiates. The power generated by the muscle is a primary means to adjust the equilibrium of posture and movement. The structural unit of the skeletal muscle is a long cylindrical type muscle fiber which contains hundreds of nucleus. The thickness of muscle fiber is about $10-100{\mu}m$, and its length is about 1-50cm. Muscle fiber is composed of myofibril that is covered with plasma membrane which is called sarcolemma. In understanding the movement of human body, it is important to comprehend the movement of bone and joint and the tension of muscle. Understanding the structure and biomechanics of muscle also provides basic information on clinical treatment of patients.

The prevalence of patients with adult spinal deformity (ASD) has been reported as high as 68%. ASD often leads to significant pain and disability. Recent emphasis has been placed on sagittal plane balance and restoring normal sagittal alignment with regards to the three dimensional deformity of ASD. Optimal sagittal alignment has been known to increase spinal biomechanical efficiency, reduce energy expenditure by maintaining a stable posture with improved load absorption, influence better bony union, and help to decelerate adjacent segment deterioration. Increasingly positive sagittal imbalance has been shown to correlate with poor functional outcome and poor self-image along with poor psychological function. Compensatory mechanisms attempt to maintain sagittal balance through pelvic rotation, alterations in lumbar lordosis as well as knee and ankle flexion at the cost of increased energy expenditure. Restoring normal spinopelvic alignment is paramount to the treatment of complex spinal deformity with sagittal imbalance. Posterior osteotomies including posterior column osteotomies, pedicle subtraction osteotomies, and posterior vertebral column resection, as well anterior column support are well known to improve sagittal alignment. Understanding of whole spinal alignment and dynamics of spinopelvic alignment is essential to restore sagittal balance while minimizing the risk of developing sagittal decompensation after surgical intervention.

Some hemiplegic patients show a particular posture that pushing away from the nonaffected side of the body. A few study has been conducted of any aspect of this syndrome. But despite the lack of a scientific basis, this term is widely used in the physical therapy of hemiplegic patients. The purposes of this study was to investigate whether pusher syndrome has an adverse impact on functional outcome. Included were all acute stroke patients admitted in a months period a hospital in Seoul. The presence of pusher syndrome was assessed by a Bobath trained physical therapist. The ability of transfer was assessed by the Functional Independence Measure(FIM), Activities of daily living by the Modified Barthel Index(MBI), and standing balance by Bohannon's Standing Balance Scale(BSBS) on admission, weekly during the hospital stay, and at discharge. Pusher syndrome was found in $52.4\%$ of the left side and $50.0\%$ of the right aide hemiplegic patients. Significant differences were found in the score of transfer, ADL and standing balance between patients with and without pusher syndrome.

PURPOSE: This study was examined the effects of coordinative locomotor training (CLT) on the postural imbalance and gait in children. METHODS: Four children were sampled as subjects. A single subject study (A-B-A') was conducted by measuring the following: baseline five sessions;, intervention phase, 15 sessions;, and postline (A') five sessions. The research period was eight weeks. The CLT program consisted of warming-up exercise, main exercise, and finishing exercise, and it was performed for one hour per day. A oneleg standing test (OLST) was performed determine the static balance. A functional reach test (FRT) was performed determine the reactionary balance. To determine the dynamic balance, the time up and go test (TUG) was performed. A 10m walking test (10 MWT) was performed to determine the walking ability. A statistical test was performed through descriptive statistics to present the average and standard deviation, and the variation rate was compared using a visual analysis method with graphs. RESULTS: As a result of CLT application, all four subjects improved the OLST, FRT, TUG, and 10 MWT compared to the intervention period baseline, and postline period. CONCLUSION: CLT appeared to improve the posture imbalance and gait in children.
