    In recent years remarkable developments have been made in rehabilitation technology. However, although technologically very advanced, these developments are not yet in widespread use in clinical settings. The reasons for this include 1. Issues with wearability and operability, 2. The availability of rehabilitation teams that can instruct patients in their use as well as the availability of equipment and the means to maintain this equipment, and 3. Issues with pricing in the public financial support system. Among these new technological developments in the field of rehabilitation, progress has been made regarding myoelectric prostheses as financial support for such devices is now available under the Act for Supporting the Independence of Persons with Disabilities and the Workmen’s Accident Compensation Insurance Law. In addition, improvements have been made in terms of wearability and operability. However, issues that remain stumbling blocks to the improved utility of myoelectric prostheses include the weight of the devices, the price, and the development of training methods for children, among others.

    Japan is entering the era of the unprecedented super-aged society. We will have many elderly and disabled people. In this situation, the emergence of rehabilitation robotics is highly anticipated. Fujita Health University is developing five kinds of rehabilitation robots ; (1) WPAL is a new gait-assist robot which reconstructs practical walking in paraplegics. (2) Independent Gait Assist is designed to assist patients with hemiplegia or lower extremity monoplegia to walk safely and comfortably. (3) Gait Exercise Assist is the robot which provides new and effective gait exercise for stroke patients with hemiplegia. (4) Balance Exercise Assist produces new balance exercises which have a lot of merits from the viewpoint of motor-learning. (5) Transfer Care Assist is aimed at reducing the physical load of caregivers, assisting the transfer and toileting of patients. Rehabilitation robots are just being realized.

  • Biomechanical influences of ankle dorsiflexion restriction using an ankle-foot orthosis on the trunk and lower extremity during stair ascending

    An ankle dorsiflexion-restricting orthosis (ADRO) to protect the joint from mechanical stresses is generally used in post-operative treatments and management after injury and/or surgery. Ascending stairs is one of the most frequent actions in our daily life that seems to impose a higher level of mechanical stresses on the body, especially in those people wearing an ADRO. However, to date, an extensive literature search by the authors has not uncovered any studies of stair ascending motion under the condition of ankle dorsiflexion restriction. We have studied the stair ascending motion while the ankle was restrictively dorsiflexed using an ankle-foot orthosis focusing on the stance phase of the lower extremity in the restricted side in healthy younger adults. Our results showed that the ankle dorsiflexion restriction was compensated for by increased trunk flexion and knee extension in the restricted side, and that the change in strategy required greater moment of hip extension and knee flexion in the restricted side. Therefore, while ankle dorsiflexion restriction can help the ankle in a rest condition, there is a possibility that stair ascending with some compensation strategies for such restriction may increase biomechanical stress in the hip joint and the knee joint.

  • The second report of invention and evaluation of a trunk brace with the joint providing resistance force : Kinetic and kinematic analysis in level walking

    The purposes of this study were to modify the previously reported trunk brace with joints providing resistance force to enhance its wearable functions and to execute kinetic and kinematic analysis of level walking wearing the modified brace. Eight healthy male subjects participated in this study. The study compared walking speed, cadence, trunk and pelvic angle and lower extremity joint moment under three different conditions, which were level walking without any orthosis, with the modified trunk brace and with a juet trunk orthosis. As a result, no change was observed in walking speed, cadence or lower extremity joint moment between level walking without any orthosis and with the modified trunk brace. However, the use of modified brace significantly increased the pelvic anterior tilt angle and slightly decreased the pelvic rotation angle compared to those of without any orthosis. These results suggest that the modified trunk brace has the function of modifying the pelvic tilt angle and this function might be useful to improve the abnormal posture of the patient with low back pain and of elderly people with posterior pelvic tilt.

  • Why not use the carbon fiber: Challenges at P.O.TEC

    For persons wearing prosthetics or orthotics, “a light-weight and strong product” is obviously the desirable feature. About half a century has already passed since carbon fiber, a light-weight and strong material, was first developed. In recent years, global warming has led to various consequences such as carbon dioxide reduction and soaring price of crude oil. In order to improve fuel efficiency, the automobile and airline industries have urgently directed their efforts to find a light-weight solution. For this reason, promotional activities have been carried out to utilize the excellent properties of carbon fiber, resulting in remarkable technological innovations. To introduce this excellent material and manufacturing technology into our prosthetics and orthotics industry, P.O.TEC is promoting the use of carbon fiber in prosthetics and orthotics so that the benefits of this advanced technology can be shared widely by users.

    We conducted a survey and analysis to investigate the current status and issues of patients who newly underwent lower extremity amputations due to peripheral circulatory disorder (PCD). Sixty patients underwent lower extremity amputations during the four-year period between 2007 and 2010 at the Department of Orthopedic Surgery of our hospital. Among them, 40 patients (66.7%) underwent amputations because of PCD, and the final site of amputation was below-knee amputation in 21 extremities (48.8%). Twelve patients (30%) died within 1 year after surgery. Nine patients (22.5%) received a prescription of prosthetic limb: 8 had below-knee amputation and 1 had above-knee amputation. The mean duration of hospital stay for patients who finally received a prescription of below-knee prosthesis was 89.6 days in PCD amputees, and 59.3 days in non-PCD (trauma) amputees.
