[Purpose] To clarify the reason why the axillary pad often deviates from the axilla during double-crutch walking using a musculoskeletal simulator. [Participants and Methods] The subjects were five healthy young males without orthopedic disease. Movement during crutch walking was measured using a 3D motion analysis system. Based on the obtained data, muscle activity related to the shoulder joint during double-crutch walking was modeled using a musculoskeletal simulation. [Results] The shoulder joint was abducted in the crutch stance phase of all subjects. [Conclusion] The results suggest that crutch walking with the shoulder blades rotated downward may suppress the activity of the abductor muscle of the shoulder joint and the activity of the shoulder joint adductor muscle.

<p> [Purpose] We aimed to clarify whether demonstration and simulated experience help the ability of care-receivers to get transferred, such as from the bed to the commode. [Participants and Methods] Participants included 28 nurses and 17 caregivers (34 females and 11 males). We developed a total floor reaction force measurement device to quantify the total loading level of care-receivers and caregivers and force shoes to quantify the loading level of the caregivers. Using these instruments, we constructed a system to measure the load on the lower limbs of the care-receivers during partial assistance. We divided the participants into the control, demonstration, and simulated experience method groups. We examined the differences in the load on the lower limbs before and after the intervention. [Results] The loads on the lower limbs of care-receivers when their buttocks were lifted from the chair were 11.7 ± 69.6, 61.8 ± 79.4, and 101.0 ± 104.0 N in the control, demonstration, and simulated experience groups. [Conclusion] These data suggest that the simulated experience method could help make use of the ability of the care-receiver to get transferred. Even care workers for the sanatorium-type sickbeds could learn to utilize the physical ability of the care-receivers using simulated experience.</p>

<p> [Purpose] Caregivers experience low back pain owing to frequent patient handling motions such as supporting the body while standing up. To prevent low back pain in caregivers, low load posture while engaging in patient handling motions is required. We determined the relationship between surface electromyography of the erector spinae muscles and subjective step length as "long" and "short" during the supporting standing-up motions of caregivers. [Participants and Methods] Ten young male participants were asked to perform supporting standing-up motion 10 times using two-step lengths comprised of subjective long and short steps. During supporting standing-up motion, we measured surface electromyograms of the erector spinae muscles and calculated the integral electromyographic values. [Results] The subjective long/short-step length normalized by body height did not differ across the participants. In addition, the subjective long-step length was longer than the subjective short-step length in all the participants. Integral electromyographic values for both the left and right erector spinae muscles in the short-step length were significantly lower than those in the long-step length when the data obtained from all the participants were used. [Conclusion] We considered that the load of the erector spinae muscle will be reduced if the short-step instead of the long-step instruction is given. In the future, instructions based on the subjective step-length variation in caregivers must be considered.</p>

Developing an anthropomorphic robotic hand (ARH) has become a relevant research field due to the need to help the amputees live their life as normal people. However, the current state of research is unsatisfactory, especially in terms of structural design and the robot control method. This paper, which proposes a 3D printed ARH structure that follows the average size of an adult human hand, consists of five fingers with a tendon-driven actuator mechanism embedded in each finger structure. Besides that, the movement capability of the developed 3D printed robot hand validated by using motion capture analysis to ensure the similarity to the expected motion range in structural design is achieved. Its system functionality test was conducted in three stages: (1) muscular activity detection, (2) object detection for individualfinger movement control, and (3)integration ofbothstages in one algorithm. Finally, an ARHwas developed, whichresembles human hand features, as well as a reliable system that can perform opened hand palm and some grasping postures for daily use.

© 2018 IEEE. In recent years, the popularity of sports climbing competitions has increased. Currently, not only able-bodied people but also people with disabilities may be interested in sports climbing. However, evaluation and guidance in climbing competitions are subjective, and those who attempt sports climbing for the first time may find it difficult to compete. Additionally, the current training methods have been developed for able-bodied people, and it is not known whether they are suitable for people with disabilities. If an objective evaluation method is established, it will be possible to propose a rational and effective teaching method for sports climbing participants. Therefore, the ultimate goal of this study is to develop an objective training method for climbing for lower-leg amputees. We studied subjects climbing a ladder that imitated the wall-climbing process and analyzed the relationship between EMG of the upper limbs and body center acceleration during climbing, which revealed a close relationship.

© 2018 IEEE. In this paper, we propose an educational system of assistance motions using wearable sensors. In addition, we will briefly introduce our proposed system and evaluate the classification method of assistance motion with different foot positions using wearable sensors as a first step toward developing an educational system. Our proposed system comprises shoe-type pressure sensors and a single inertial measurement unit attached to the trunk. The proposed method classifies assistance motion by machine learning technique using feature quantities obtained from wearable sensors. Herein we evaluated whether the proposed method could classify assistance motions for supporting standing-up with different foot positions. Participants were five young men and were asked to perform two motions with different two feet anteroposterior positions positions ("short step length" and "long step length"). The results showed that the proposed method was able to classify the two motions with 90% or higher accuracy for all participants. Therefore, we considered that the method could be used in the educational system.

© 2018 IEEE. In order to provide a notification system for the blind awaiting a bus, a classification of viewpoints is necessary. In a previous study, we classified the viewpoints in non-congested traffic using road features extraction. However, the viewpoints in congested traffic have not yet been discussed; hence this paper proposes a viewpoints classification using car distribution on the road in congested traffic. The study aimed to classify the viewpoints to two classes as "Good Viewpoints" and "Bad Viewpoints" with 100 images for each class. The experimental results showed a 76% accuracy of the proposed method.
