Objective: This study was conducted to confirm the effect of physiotherapy on the balance and walking in dog with sciatic nerve injury and degenerative arthritis of stifle joints. Design: Single case study Methods: The dog walked abnormally for six months and was administrated in S animal hospital. The dog's right hindlimb was operated for cranial cruciate ligament repair and the dog had been taking a nonsteroidal anti-inflammatory analgesic before being refered. There was severe degenerated osteoarthritis in the right hindlimb. During stance and walking, the right hindlimb was often shown partial weight bearing. The dog's left hindlimb was shown plantigrade stance and walking. The radiograph was shown an intact calcaneal tendon in the left hindlimb. In the neurologic examination, sciatic nerve injury in the left hindlimb was confirmed. The dog was treated using muscle strengthening, proprioceptive exercise, underwater treadmill and Laser therapy two, or three times a week for 3 months. At the 10th and 17th treatment, it was evaluated through stance and gait analyzer system to measure dog's balance and walking. Results: 3 months following physiotherapy, the dog's balance was improved in center of pressure(COP). And peak vertical force(PVF), vertical impulse(VI) was increased in right hindlimb and double stance was decreased. Conclusions: Physiotherapy may have improved the prognosis in this dog with severe osteoarthritis and sciatic nerve injury. This study suggested that animal physiotherapy is a valuable way to improve balance and walking.

Background: Fall-related injuries in older adults are a major health problem, and the risks and mechanisms of these injuries should be affected by race, culture, living environment, and/or economic status. Objects: Research articles have been systematically reviewed to understand fall-related injuries in older adults in South Korea. Methods: 128 published research papers have been found through the Korea Citation Index and the Korean Studies Information Service System, and reviewed in various perspectives, including incidents, fall death rates, medical costs, causes, injury sites and types, locations where falls occurred, prevention strategies, scholarly fields interested in fall injuries, and the role of physical therapy. Results: Fall-related injuries were found to be more common in women than in men, and the number of incidents increased with age, with the highest rate found in individuals over 85 years old. Risk of fall injury was associated with education level, comorbidities, and fear of falling. Common places where falls occurred included the bathroom, living room, stairs, and hallway. Common types of injury included bruises, fractures, and sprains in the lower extremities. Intervention strategies included exercise programs, education, and protective clothing. Scholarly fields interested in fall-related injuries in older adults included medicine, nursing, physical therapy, occupational therapy, physical education, pharmacology, oriental medicine, biomedical engineering, design, clothing, and textiles. Physical therapy intervention using proprioceptive neuromuscular facilitation has been used to improve one's balance. Conclusion: Any movement during the activities of daily living can lead to a fall. Physical therapists are highly educated to analyze human movements and should be involved in more research and practices to solve fall-related injuries in older adults.

본 연구는 단순반복 작업자의 근골격 질환 발생 급증에 따라 이들 발생 원인과 업종간 발생 정도에 대한 차이를 도출하기 위해 기존의 단일 업종 조사에서 벗어나 다양한 업종간 장시간의 단순반복작업에 따른 발생 실태 차이를 도출하기 위해 현장 실태조사를 하였다. 먼저 기초 실태를 조사한 결과 대부분의 근로자들이 근골격계질환을 경험하고 있는 것으로 나타났다. 그러나 병원치료를 받은 경우는 거의 없는 것으로 나타났으며 이러한 결과는 근골격계질환이 작업에서 발생되는 것이기는 하나 그 위험성을 아직 깨닫지 못하고 있기 때문인 것으로 판단할 수 있다. 또한, 담당업무별로도 발생빈도에 있어 근골격계질환자가 발생하는 비율이 직종에 따라 다소 다른 것으로 나타났다. 특히, 성형, 운전, 포장업무에서 많이 발생하고 있는 것으로 나타났는데 이의 예방을 위해서는 각 담당업무별로 근골격계질환 노출 정도에 맞추어 성형업무에서는 자동화기기로의 대체와 작업장 환경 평가결과 제시된 개선계획에 대한 철저한 이행 및 회사차원에서의 지속적인 관심과 정밀 측정 기법을 적용한 지속적 연구가 요구된다.

Purpose: Little information has been published regarding minor burn injuries in infants, most of which are preventable. To fill this research gap, this study explored the patterns and mechanisms of burn injuries in infants to ascertain whether such incidents can be prevented. Methods: This was a retrospective study, based on data collected prospectively from all infants (<12 months old) admitted to our hospital with burns in the four-year period between January 1, 2015 and December 31, 2018. A medical record review provided basic demographic information, such as age at the time of injury, sex, cause of injury, duration of treatment, operative treatment, and the extent and type of burn, as well as the anatomical region involved. Results: Fifty-seven infants were diagnosed with burn injuries, with scalding being the most common type (47%), followed by contact (32%) and steam (14%). Seven infants of eight steam burn patients injured by pressure cooker. Superficial second degree was the most common depth of injury (72%) followed by first degree (17%) and deep second degree (8%). Average age per injury type was calculated by independent T-test. Average ages of patients with contact and steam burns were significantly lower (7.06 months; P=0.19) and higher (9.25 months; P=0.005), respectively, than for other burn types. Conclusion: Given that infants cannot control their body movements, talk, or manage by themselves, they are entirely dependent on the proper care of adults. Consequently, in addition to the prevention of burns, special care should be taken for the pressure cooker.

The objective of this paper is to develop a powered wheelchair controller based on EMG for users with high-level spinal cord injury using a proportional control scheme. An advantage of EMG is relative convenience of acquisition by a surface electrode to users. Direction information can be easily extracted from two EMG channels and force information can be acquired by proportional relationship between the amplitude of EMG and user's power, respectively. Pattern classification algorithm is a threshold method with a supervised learning process. Furthermore, the emergency situation can be avoided using an interrupt function. We evaluated the performance of powered wheelchair controller by navigating a pre-defined path with three non-handicapped people. The results show the feasibility of EMG as an input interface for powered wheelchair and other devices for the seriously disabled.

현재 어깨상해는 많은 운동 참여자에게 빈번히 발생하는 질환이다. 운동 동작 시 올바르지 못한 어깨정렬로 인해 어깨의 안정성이 저해되고 그로인해 다양한 상해들이 유발되어진다. 운동 동작 시 팔꿈치와 손목간의 올바른 정렬은 어깨 안정성에 중요한 요소이다. 따라서 본 논문에서는 팔꿈치보호대와 손목밴드에 센서를 부착하여 웨어러블 장비와 함께 융복합 IT기술을 기반으로 하여 팔꿈치와 손목간의 정상범위를 직관적으로 제시하여 동적 운동 상황에서의 상해를 예방하고자 한다.
