Purpose: To evaluate the incidence and risk factors of ipsilateral reamputation after lower limb amputation in the patient with diabetic foot lesions. Materials and Methods: Between May 2005 and June 2009, 88 patients who underwent lower limb amputation were analyzed. Group 1 consisted of 73 patients who didn't have a ipsilateral reamputation after lower limb amputation and group 2 consisted of 15 patients who underwent reamputation. We compared several factors between two groups, such as age, gender, BMI, ABI, Wagner classification, wound culture, site of amputation, vascular surgery, the period of diabetes mellitus, chronic renal failure. Results: Fifteen (17%) of 88 patients had a ipsilateral limb reamputation and 13 patients (87%) of them underwent reamputation within 6 months. When we compared the two groups, average age was 59.3 (range, 48-74 years); 62.9(range, 44-78 years). Age was significantly associated with reamputation rate (p=0.02) and no reamputation after initial amputation above ankle joint was found. Other factors did not show statistically difference between both groups. Conclusion: There were no significant difference between diabetic limb amputation and reamputation group in our concerned risk factors except age and amputation level. There should be careful consideration when determine level of amputation in diabetic foot lesions especially in elder patients.

The two groups each consisting of 28 people who had an adult hemiplegia due to a brain injury received two different methods of exercises to reduce the angle to which the affected lower limb rotates externally. The comparisons between the two groups were made for the changes of the angle in external rotations measured between pre and post test. The static balance index values taken during pre and post tests were also compared. In addition, the correlations of the angle to which the affected lower limb rotates externally with static balance index values were analyzed. The result were as follows: 1. A statistical analysis indicated that in group one having taken simple R.O.M exercises, the angle to which the affected lower limb rotates externally and the static balance index values were both significantly different between pre and post test (P<.01). 2. A statistical analysis indicated that in group two having taken a pattern movement, both the angle to which the affected lower limb rotates externally and static balance index values were significantly different between pre and post test (P<.01). 3. A significant difference between simple R.O.M exercises group and pattern movement exercises groupwas shown only for the angle to which affected limb rotates externally not for static balance index values (P<.01), 4. Pearson correlation coefficient for the angle to which the affected limb rotates externally with static balance index values was found to be significant only in pattern movement exercises group (P < .05).

The purpose of this study is to estimate how much the motility of affected and unaffected lower limb respectively would have effects on their ambulation through comparing the difference between their affected and unaffected lower limb and studying the correlation between such difference and their ambulation. In addition, the study also intends to find out remedial measures suitable for improving their ambulation with relevant physical treatment. To do this, a quantitative electromyogram(QEMG) test was done to hamstring of affected and unaffected lower limb so as to yield IP values. Based on such IP values, RMS(root mean square) values as the total sum of IP values were found with QEMG analysis system (made by Medelec Co.) and then the ambulation depending on the difference in muscular strength were analyzed by ink-foot print method as well as the corresponding statistics were processed by T-test through SPSS. The differences in muscular strength of hamstring in unaffected limbs of hemiplegic patients only affect stride length. It was statistically significant. The effect of difference in muscular strength of the hamstring in affected limb of hemiplegic patients on their ambulation was very different between strong and weak group in terms of walking velocity, step per minute, stride and step length, showing statistically significant difference(p<.05). Although there was a difference in the step length of the affected limb, it was not statistically significant(p>.05). For the unaffected hamstring, there were significant differences of stride length between in unaffected limb and in affected limb. For the affected hamstring, there were also significant differences in walking velocity, step per minute, stride and step length. Besides, it was found that the difference of the muscular strength between strong and weak group was at the highest.

거동이 불편한 노인 및 장애인의 이동을 위한 휠체어 사용 시, 사용하지 않는 상 하지의 근력 저하 등 운동 능력의 감소를 초래할 수 있다. 특히, 척수손상 및 뇌졸중 편마비와 같은 중증 장애인은 거동이 제한되어 운동이 부족하고 근력 유지가 어렵다. 본 논문에서는 이러한 중증 장애인의 특성을 고려하여 상 하지 운동 및 재활훈련이 가능한 지능형 휠체어 로봇 시스템을 설계하였다. 이 시스템은 전동 휠체어, 개인의 특성 파악을 위한 생체인식모듈, 그리고 상 하지 재활 로봇으로 구성되어 있다. 본 논문에서는 개발된 로봇의 설계 및 구성에 대해 설명하고 운용 방법을 제시한다. 또한, 제안한 시스템의 추종 성능을 검증하기 위하여, 비장애인 피험자를 대상으로 재활 운동 수행시 생체 신호 변화에 따른 위험상황 분석과 휠체어 로봇이 이동하면서 상 하지 재활운동 기능에 대한 성능평가를 수행한 결과, 피험자의 재활 운동 수행 시 위험상황 분석에 대한 평균 정확도는 86.7%, 관절각도 최대 오차는 상지 2.5도, 하지 2.3도로 재활 운동 수행에 충분한 추종성능을 나타냈다.

Purpose: To investigate the spatial distribution of diabetes-related lower limb amputations and analyze the relationship between the spatial distribution of diabetes-related lower limb amputations and regional factors. Materials and Methods: This study was performed based on the data from the Korean Health Insurance Review and Assessment Service, in 2016. The unit of analysis was the administrative districts of city·gun·gu. The dependent variable was the age- and sex-adjusted incidence of diabetes-related lower limb amputations and the regional variables were selected to represent two aspects: socioeconomic factors, and health and medical factors. Along with traditional ordinary least square (OLS) regression analysis, geographically weighted regression (GWR) was applied for spatial analysis. Results: The age- and sex-adjusted incidence of diabetes-related lower limb amputation varied according to region. OLS regression showed that the incidence of diabetes-related lower limb amputation had significant relationships with the health and medical factors (number of healthcare institution and doctors per 100,000 population). In GWR, the effects of regional factors were not consistent. Conclusion: The spatial distribution of the incidence of diabetes-related lower limb amputations and the effects of regional factors varied according to the regions. The regional characteristics should be considered when establishing health policy related to diabetic foot care.
