Two standard methods of cane length measurements were compared to find which methods really achieve the elbow flexion of 20 degrees to 30 degrees Twenty-four patients with hemiplegia who were ambulatory participated in this study. Method I : Length of the cane measured from the floor to the top of the greater trochanter. Method II : Length of the cane measured from the floor to the distal wrist crease with the arm at the side. Using an adjustable cane, each individual was fitted according to the two methods, and elbow angle was measured after each adjustment. The elbow angle according to Method I and Method II was $46.4{\pm}20$, $44.3{\pm}12.2$, respectively. No significant difference was found in the elbow angle or the cane length between the two methods. Of the 24 participants, 5(20.8%) measured according to method I and 3(12.5%) measured according to method II showed the elbow angle between 20 degrees and 30 degrees. These low predictive rates of agreement between ideal cane length and actually achieved elbow angle showed that these two methods which have conventionally been accepted as a standard to measure ideal cane length need to be revised through further research.

This study investigates the influence of cane length on the weight distribution of the elderly in a standing position. Thirty participants were evaluated using two different cane lengths based on measurements of distal wrist crease to ground (WC cane), and distance of greater trochanter to ground (GT cane). A limloader was used to determine the weight distribution on the subject. It was found that 6.5% of body weight was supported on a GT cane and 7.7% of body weight supported on a WC cane in a standing position. Results suggests that more weight is distributed on a WC cane than a GT cane in the elderly.

This paper presents a sensor-based cane mechanism for walking aid of the visually impaired person. We also describe an approach to decide properly the length of the specified cane mechanism. The cane mechanism has some sensors to identify the possibility of a collision between the cane user and an object and/or a person, and a signal processing unit that enables the user to recognize such a collision is attached in the mechanism. Thus, the walker using this cane can recognize in advance the possibility of such a collision in his walking process. Consequently, it is helpful for the visually impaired person to walk on a pedestrian road safely. The feature of the proposed cane mechanism and its availability have been shown through experimental works in a typical walking environment.

본 연구는 성인 뇌졸중 환자의 보행기능을 향상시키기 위해 사용되고 있는 보행보조기의 가장 이상적인 길이를 제시함으로써 뇌졸중 환자만을 위한 전문화된 맞춤형 보행보조기 길이의 사용을 독려하기 위하여 실시하게 되었다. 그 결과, 지팡이 높이에 따른 성인 뇌졸중 환자의 보행균형, 보행분석에서 보행의 속도 증가를 위해서 몸통 굴곡을 통한 무게 중심이 아래쪽에 위치하고, 하지근육의 활성도 증가를 위해서 몸통 신전을 통한 무게 중심이 위쪽으로 이동하여 척추 기립근의 수축으로 뇌졸중 환자의 지팡이 높이에 따른 균형과 보행 변화의 근거를 제시한다.

The purpose of this study was to assess of cane use on the hemiplegic gait of strock patients in temporal and spatial variables. Subjects were thirteen including 8 men and 5 women. They could walk independently without cane, To compare the effect of walking with and without a cane, temporal and spatial variables was measured using GAITRite. Cane walking demonstrated increased stance time on the affected side, and swing time, step length on the sound side were increased, and base of support was decreased. In conclusion, hemiplegic gait pattern of strock patients were improved with cane than those not using a cane.

Purpose: This study was undertaken to determine whether the position of cane use affects the distribution of weight-bearing on both feet of children with hemiplegic cerebral palsy in a standing posture. Methods: Twenty participants with cerebral palsy were recruited as volunteers for this study. Using the Zebris FDM-System, weight-bearing distribution according to the method of using a cane was measured under three conditions in randomized order: (1) standing unaided (no cane); (2) standing with the affected side using the cane; and (3) standing with the non-affected side using the cane. The cane was matched by measuring length-from-floor to the greater trochanter of the subject, and was placed 15 cm outward from the little toe on the supporting side. Results: Evaluating the method of using a cane under the three conditions, we determined that pressure of the foot on the affected side was higher in the order: standing with affected side using cane > standing unaided (no cane) > standing with non-affected side using cane (p<0.05). In the post-hoc analysis, a significant difference was observed between (i) standing unaided (no cane) and standing with the affected side using cane, and (ii) standing with affected side using cane and standing with non-affected side using cane (p<0.05). Conclusion: This study suggests that induced weight-bearing methods using a cane on the affected side could increase the weight-bearing capacity on the affected side in children with spastic hemiplegic cerebral palsy, which will have a positive effect on reducing asymmetry weight support.

Objective: There are no guidelines for choosing appropriate gait assistive devices. The aim of this study was to evaluate gait assistive devices in patients with Parkinson's disease. Method: We evaluated 15 individuals with Parkinson's disease who did or did not use one of two different devices including canes and two-wheeled walkers. Data were collected using the GAITRite system. Results: Participants in the group using canes and two-wheeled walkers had significantly increased double support time and decreased gait velocity, normalized gait velocity, and stride length compared with those who did not. Participants who used a two-wheeled walker had significantly decreased gait velocity, normalized gait velocity, and stride length compared with those who used a cane. Furthermore, participants who used a two-wheeled walker had significantly decreased coefficients of variation for step time, stride length, and swing time compared with those who used a cane. Conclusion: Our results indicated that the two-wheeled walker offered the most consistent advantages for decreasing the risk of falling.

Monosodium glutamate는 많이 쓰이고 있는 화학조미료이다. 인간을 비롯하여 생쥐, 원숭이(Rhesus monkey), 초파리등의 동물에 대한 MSG의 영향을 실험 검토하여 MSG가 해롭다 또는 그렇지 않다는 상반된 여러 보고가 있다. 초파리(Drosophila melanogaster)의 발생에 대한 MSG의 영향을 조사하여 이렇듯 엇갈린 보고를 검토 확인할 목적으로 여러가지 농도의 MSG와 cane sugar media(대조구)에 두 계통의 초파리(Oregon-R와 Sinchon-I)를 사육해서 우화해 나온 $F_1$초파리의 수를 조사 검토한 결과는 다음과 같다. 1) MSG의 처리는 초파리의 어느 계통에서나 다 같이 그 농도가 증가함에 따라 발생에 억제적 효과를 나타내는 동시에 10% 이상의 농도에서는 성층의 생육조차 불가능하였다. 2) Cane sugar는 초파리 발생에 억제적이라기 보다 오히려 촉진적 효과를 보이는 것같다. 3) MSG나 cane sugar처리구에서 다 같이 Sinchon-I이 Oregon-R보다 $F_1$ 산출수가 많았는데 이것은 Sinchon-I이 Oregon-R보다 생식 및 생존력이 강함을 암시하여 그 원인으로서 사육하는 동안 근친교배되는 기간의 차이라고 생각된다. 4) Muller-5 test는 부정적 결과를 나타냈는데 이것은 MSC가 mutagenic effect가 없음을 시사하고 있다. 5) MSG의 초파리 발생에 대한 억제적 효과에 관한 생리학적 기구는 아직 미지의 문제인데 이것은 조만간 해결하여야 할것이다.

Purpose : This study investigated the validity of crosswalk signal time length with regards to elderly stroke patients. Methods : We recruited 60 elderly adults sixty years of age or older for our study. The participants were divided into three groups.Group A consisted of 20 healthy participants with no walking aids. Group B consisted of 20 stroke patients with no walking aids. Group C consisted of 20 stroke patients using a cane as a walking aid. We measured the walking times of participants for 7 m, 14 m and 21 m lengths. Results : Using an independent t test, there was a statistically significant difference in the walking times between Group A and Group B for all lengths. There was a statistically significant difference in the walking times between Group A and Group C for all lengths. There was no statistically significant difference in the walking times between Group B and Group C. There was a statistically significant difference between the three group when using ANOVA. Conclusion : From the results of this study, we infer that the signal times at crosswalks are inappropriate for elderly stroke participants who use a cane as a walking aid. Therefore further research should be conducted to determine the appropriate amount of additional time needed for the elderly to safely cross the street.
