    In a previous study, we have demonstrated in healthy subjects that a shoehorn-type ankle-foot orthosis with a T-strap is effective in correcting adduction, which is the horizontal movement of the ankle joint in resting standing position. However, in individuals with increased muscle tone in the plantarflexor muscles requiring a T-strap, use of an articulated ankle-foot orthosis with dorsiflexion assist is recommended, to avoid range-of-motion limitation occurring in the ankle joint. In this study, we fabricated a prototype ankle-foot orthosis by incorporating a T-strap in a plastic ankle-foot orthosis with a Tamarack ankle joint for dorsiflexion assist and plantarflexion stop. We also evaluated the effectiveness of the prototype in correcting ankle joint inversion in healthy subjects. From the results of gait measurement, the angle of ankle joint inversion was reduced during the stance phase excluding initial contact when the ankle-foot orthosis with T-strap was worn compared to when the orthosis without T-strap was used. These results demonstrated the correction effect of the prototype ankle-foot orthosis.

    In hemiplegic stroke patients, rehabilitation is started early in the onset. Walking exercises using a knee-ankle-foot orthosis are performed in patients with severe hemiplegia, but conventional knee-ankle-foot orthosis knee joints cannot be adjusted for the extension range of motion of the knee, or require a tool to adjust the angle. For example, there are many cases in which the lower limbs of hemiplegic patients with limited joint range of motion are painful to wear and require time to put on. Based on the above, we have developed a knee joint that enables angle adjustment and fixation without tools.

    The selection and recommendation of appropriate prosthetics and orthotics (PO) in physical therapy is recommended in guidelines and is considered to be an important component of this medical speciality. However, although there is a high awareness of the importance, there are reports of insufficient pre-graduate education on PO. The aim of this study was to identify the experiences of physiotherapy students in long-term clinical practice with prosthetics and the knowledge they felt they needed to acquire prior to practice. The target group consisted of 75 students from the physical therapy department, who answered questions via their personal electronic terminals. The content of the survey included a breakdown of the practical training facilities, whether they had experience with PO, the PO they had experienced, what they had been briefed on, what they had experienced and the knowledge they thought they needed before practical training. The survey showed that approximately 80% of students had experienced PO during their practical training. The results showed that most of the involvement centered on fitting and orthotic gait assessment, suggesting that students tended to reflect on their knowledge of basic areas through experience. There is a need to provide information to students prior to practical training and incorporate this as a measure in the future.

    The purpose of this study was to determine the immediate effect of the use of a foot orthosis on the shock-absorbing capacity of the knee joint for over-pronation of the subtalar joint. The arch height ratio and Q-angle in the static standing posture, the knee extensor muscle activity during level walking as a movement task, and the shock-absorbing capacity of the knee joint were compared with and without the intervention of a foot orthosis. The results showed that the use of a foot orthosis improved the arch height ratio and Q-angle and tended to increase muscle activity, but did not show an immediate effect on shock-absorbing capacity.

    There are few epidemiological studies of multiple amputations in Japan. In this study, we conducted a survey using a database operated by the National Rehabilitation Center for Persons with Disabilities to clarify the epidemiological characteristics of multiple amputees. As a result of analyzing 140 multilimb amputees who were subject to prosthetic limbs made at our center during the 41 years from 1979-2019, bilateral upper limb amputation was mainly male amputation due to industrial accidents, bilateral lower limb amputation was mainly caused by traffic accidents, diabetes and angiogenic diseases, and the proportion of women was higher than that of unilateral upper and lower limb amputation and triple limb amputation, and all cases of unilateral upper and lower limb amputation and triple amputation were traumatic injuries mainly in traffic accidents, and no characteristics were found in gender. Quadruple amputation was mainly caused by diseases such as purpura fulminans, and the proportion of women was the largest compared to other amputation sites, and the average age was higher. Over time, the number of quadruple amputees has increased, the number of amputees has aged, and the number of amputees due to disease has tended to increase.

    Using toys in prosthetic training for children with congenital limb deficiency is useful for them to get trained while having fun. We investigated the toys used in training of upper limb prostheses for children in National Rehabilitation Center for Persons with Disabilities in 2012-2020 to learn what kind of toys were suitable for training. We counted the number of times that the toys were used in the training for 23 children under 3 years old. One hundred thirty types of toys were used in 293 training sessions, and 80% of them were ready-made. There weren’t many types of toys that were used repeatedly. The toys used frequently had simple functionality, and these were able to be used for children at different developmental stages. Toys that weren’t appropriate for the child’s developmental stage or that limited the manner of use were used less frequently. Some toys had different frequencies of use between boys and girls. It was suggested that ready-made toys are effective for training depending on how they were used. Considering suitability for the developmental stage of the target child and acceptability to many children is important when selecting a toy or giving function for training to a ready-made toy.
