In this study, the concept of autonomous mobility is applied to a gait support mobile robot. The aim of the development of the service robot is to assist the elderly with gait rehabilitation. This study proposes an ergonomic service robot design parameter. The gait assistant path pattern is derived from analysis of the elderly gait. A lever is installed in the AMR in order to measure both the pulling force and the leading force of the elderly. The path generation of the mobile robot is developed through consideration and analysis of elderly gait patterns. The ergonomic design parameters (dimensions, action scope and working space) are determined based on moving scope of the elderly. The gait assistant mobile robot was offered the elderly guide service and internet service based on the ergonomic design parameters.

Purpose: The purpose of this study was to analyze the necessity of home visit rehabilitation therapy by rehabilitation professionals working at social welfare facilities. Methods: The subjects of this study were 227 rehabilitation professionals (social worker, nurse, physical therapist, occupational therapist, speech-language therapist, special education teacher, and staff of institutions for the disabled who were working at community rehabilitation centers. The data were collected over 65 days (2008. 09. 10~11. 14). The results were analysed statistically by the Chi-square test. Results: The results are as follows: Long-term care service was established in Korea by the Ministry of Health in July, 2008. But there are limits to their being able to provide various rehabilitation services for chronic patients and old people. According to a recent survey, almost all rehabilitation professionals (N=227) stated that home visit rehabilitation therapy is necessary. Conclusion: In Korea, the long-term care service has a nursing service and a service supporting physical activities of daily living, but not physical therapy. So, home visit rehabilitation services should include physical therapy, rehabilitation exercise, and pain management.

Disorders of the shoulder in which conservative management is indicated as a primary treatment include idiopathic frozen shoulder, atraumatic instability. acute calcific tendinitis , subacromial impingement syndrome, partial thickness or small full thickness tear of the rotator cuff, and chronic rotator cuff tear in elderly population. Aside from medication and various physical modalities used for relief of pain, the mainstay of orthopaedic rehabilitation consists of stretching of the tendons and capsulologamentous complex, and strengtnening of rotator cuff muscles as well as surrounding muscles. However, orthopaedic rehabilitation in chronically painful conditions of the shoulder differs in detail according to the specific diseases or injuries, And it is important to make the rehabilitation program that can be undertaken by the patients rather than adhering to a fixed schedule. Also the program should be changed as the condition of the patient improves or deteriorates. Nevertheless there are basic rules of stretching and strengthening , which should always be observed in applying orthopaedic rehabilitation treatment.

This study was designed to examine, using Rasch analysis, the rating scale performance of the Korean version of the Berg Balance Scale (BBS). The subjects were 95 elderly people at community dwelling. Subjects (19 men, 76 women) ranged in age from 65 to 91 years. Rasch analysis was then done by means of the Winsteps program to determine the validity and reliability of the Korean version of the BBS evaluation tools for elderly people. The results were as follows: Twenty-one elderly people were excluded for misfit persons. Three items were found to be misfits and the order of item difficulty of the remaining 11 items was arranged. Elderly people BBS ability is indicated by -.94~7.41 logit, and the transformation formula is score=(logit score+.94)/$(.94+7.41){\times}100$. This transformation formula can be applied to Korean elderly people for balance ability. In the order of difficulty of evaluation items, the most difficult item was "Standing on one foot" and the easiest item was "Standing to Sitting". In conclusion, the Korean version of BBS evaluation tool for the elderly people has been proved valid and will be useful in clinical practice and research in Korea.

비데는 최근 상당수가 의료기능을 포함하여 다목적용으로 개발되어지고 있다. 그러나 이러한 비데를 사용함에 있어서도 장애인과 고령자가 일반인에 비해 추구하는 니즈들이 더 다양하고 심지어 장애유형별로도 제각각 요구사항들이 다르다. 따라서 본 연구는 고령자 및 장애인이 배변활동에서 요구하는 실질적인 니즈에 대해 조사하였으며 장애유형별로 니즈를 비교하여 분석하였다. 설문 조사는 고령자 39명, 장애인 120명을 대상으로 진행 되었다. 설문문항은 각 비데업체별 UI 인지능력 비교, 자동 물 내림 기능 선호도, 비데 컨트롤러 위치, 양각화 필요성에 대한 문항들로 이루어져 있다. 결과는 비데 UI인식에서 고령자와 장애인이 비슷한 비율로 제일 직관력이 뛰어난 아이콘을 선정하였다. 자동 물 내림 기능 선호도에 있어서는 고령자와 신체적기능장애인이 약 1:9의 비율로 자동 물 내림을 선호하였지만 감각적 기능장애인의 경우 5.1:4.9로 오히려 수동 물 내림을 더 선호하였다. 컨트롤박스 위치 또한 고령자와 신체적 기능장애인은 약 5:5의 비율로 차이가 미비했지만 감각적 기능장애인의 경우 2:8의 비율로 벽면 부착 보다는 비데 우측부착을 선호하는 것으로 나타났다. 시각 장애인에게만 해당되는 양각화 기능 선호에서는 점자지원보다 양각화 또는 점자와 양각화 모두 지원을 선호하는 응답자가 약 1:9의 비율로 높게 나타났다.

Purpose: This study aimed to examine the effects of proprioceptive neuromuscular facilitation (PNF) upper and lower limb coordinated exercises on balance in elderly women. Methods: The study was conducted with 27 elderly women who were at least 65-year-old. The subjects were randomly assigned to a PNF upper and lower limb coordinated exercise group consisting of 14 subjects and an aero step balance exercise group consisting of 13 subjects, and the exercises were performed for 30 minutes, three times per week, for eight weeks. One Leg Stance Tests (OLST), Functional Reaching Tests (FRT), Four Square Step Tests (FSST), and Timed Up and Go (TUB) tests were conducted before and after the exercises to evaluate the subjects' static balance ability and dynamic balance ability. Among the collected data, the subjects' general characteristics were evaluated using descriptive statistics, the intra-group differences of the test results before and after the intervention were compared using paired sample t-tests, and the inter-group differences in the results before and after the intervention were evaluated using independent sample t-tests. The statistical significance level was set to 0.05. Results: Among the OLST, FRT, FSST, and TUG tests, the experimental group showed positive FSST results that were statistically significantly greater than the control group; the results of the other tests were also more positive for this group, but the differences between the groups were not statistically significant. The magnitude of the effects for both groups was clinically significant. Conclusion: Since inter-limb coordinated exercises for PNF applied to elderly women were found to produce good results for both static balance ability and dynamic balance ability, these exercises can be used in exercise programs to improve balance in elderly women.

Objective: The purpose of this study was to quantitatively evaluate the Wii Balance Board (WBB)-based jump performance for the elderly and to confirm the difference in jump performance according to age. Design: Cross-sectional study. Methods: 40 young adults (aged 22.5±2.2 years) and 33 elderly (aged 75.1±5.2 years) without orthopedics disease participated in this study. Standing on the WBB then, with the signal "start," jump vertically to the maximum height at which you can jump, land on the force plate after jump and keep it standing on both feet. All subjects were required to practice the jump sufficiently before starting the measurement, each measuring three times, and the mean values were used. A one-minute break was provided between each trial. Evaluators waited within 1meter for every test to prepare for fall. Results: The vertical ground reaction force of elderly and young adults when jumping using WBB showed a significant difference (p<0.05) and demonstrated discriminant validity. Between two groups, there were significant differences in overall jump time (p<0.05), maximum value (p<0.05), minimum value (p<0.05), center of pressure (COP) pathlength (p<0.05), and flight time p<0.05). Conclusions: This study found that performing the vertical jump, the elderly showed longer jump time, lower vertical ground reaction force, COP pathlength and shorter flight phase than healthy young adults using WBB and demonstrated that as a measurement tool, WBB discriminated vertical jump performance between elderly and young adults.

Weight bearing is effective during rehabilitation of gait, in the elderly and disabled people. Various training devices using weight bearing function were developed along with treadmill walking; however, no device has been developed in conjunction to walking on the ground. Here, we designed a rail type frame of a gait rehabilitation system for body-weight support (BWS) function, and analyzed its mechanical safety in the static weight bearing condition of a vertical axis. Computational simulations were performed to analyze structure of the driving parts, which are connected with a rail and driving rollers and the lower plate of the BWS. Structural analyses showed the drivers and BWS were safe, when simulated at 135kg weight under static conditions. Thus, this rail type rehabilitation system can be used for gait training of the elderly and disabled.

본 연구는 심근경색 환자에서 고강도 간헐적 운동 프로그램이 나이에 따라 심폐운동 기능에 미치는 효과를 비교하여 노인환자에서의 효과를 알아보고자 하였다. 2015년에서 2017년까지 심장 재활을 실시하였던 환자 중 외래 경과 관찰중인 환자의 기록을 후향적으로 분석하였다. 총 39명 (60세 이상의 노인 20명, 19명의 60세 미만의 젊은 환자군)이 연구에 포함되었다. 고강도 간헐적 심장 재활프로그램은 준비운동 5-10 분, 고강도 간헐적 유산소 운동 28분 및 마무리 운동 5-10분으로 구성되었다. 대상자들은 초기 운동부하 검사 결과를 바탕으로 심장재활 치료실에서 심전도 감시 하에 유산소 운동을 여유 산소 섭취량을 기준으로 70-90%의 고강도의 훈련 4분, 60-70% 로 3 분가량의 일반적인 강도의 훈련을 반복적으로 4 회간 실시하고 마무리운동을 시행하였다. 심폐기능은 심장재활 실시 전, 후로 운동부하 검사에 의해 평가되었다. 심장재활 후 두 군 모두에서 운동기능의 개선의 효과가 있었다. 심장재활을 실시하기 전 시행한 운동 부하 검사에서 최대 산소 소모량, 최대 운동시의 신진대사 해당치, 무산소 역치 등이 60 세 이상의 노인에서 의미 있는 운동 기능 저하가 관찰되었다(p<0.05). 심장 재활 전과 후의 운동 능력을 비교하였을 때, 두 군에서 최대 운동 가능시간, 심근부담률, 최대 심박수, 안정시 심박수, 최대 산소 소모량, 최대 산소소모량 측정시의 최대 환기량, 최대 운동 시 의 신진대사 해당치, 무산소 역치 지표에서 통계학적으로 유의한 변화가 관찰되어(p<0.05), 고강도 간헐적 운동방법은 노인환자에게서도 안전하며 효과적이다. 그러므로 60 세 이상의 노인 환자에서의 효과적인 고강도 간헐적 운동 참여를 확대하는 것이 필요할 것으로 생각된다.
