<p><b>Objective: </b>We have developed a robot for gait rehabilitation of paraplegics for use in combination with functional electrical stimulation (FES). The purpose of this study was to verify whether the robot-derived torque can be reduced by using FES in a healthy-person pseudo-paraplegic model.</p><p><b>Methods: </b>Nine healthy participants (22–36 years old) participated in this study. The robot exoskeleton was designed based on the hip–knee–ankle–foot orthosis for paraplegia. Participants walked on a treadmill using a rehabilitation lift to support their weight. The bilateral quadriceps femoris and hamstrings were stimulated using FES. The participants walked both with and without FES, and two walking speeds, 0.8 and 1.2 km/h, were used. Participants walked for 1 min in each of the four conditions: (a) 0.8 km/h without FES, (b) 0.8 km/h with FES, (c) 1.2 km/h without FES, and (d) 1.2 km/h with FES. The required robot torques in these conditions were compared for each hip and knee joint. The maximum torque was compared using one-way analysis of variance to determine whether there was a difference in the amount of assist torque for each gait cycle.</p><p><b>Results: </b>Walking with the exoskeleton robot in combination with FES significantly reduced the torque in hip and knee joints, except for the right hip during extension.</p><p><b>Conclusions: </b>In the healthy-participant pseudo-paraplegic model, walking with FES showed a reduction in the robot-derived torque at both the hip and knee joints. Our rehabilitation robot combined with FES has the potential to assist paraplegics with various degrees of muscle weakness and thereby provide effective rehabilitation.</p>

<p>大腿四頭筋腱断裂に対し，スーチャーアンカー法とpull out法を用いた修復術を直視下・鏡視下に行い，ともに良好な成績を得た．手術時間は鏡視下で長く，手術創は直視下が大きい点が差として挙げられた．患者背景や施設体制に応じて適切な術式を選択するべきである．</p>

We have developed a gait training rehabilitation robot “Akita Trainer” for hemiplegic patients. It has servomotors attached to the hip and knee joints of the exoskeleton, and driving it enables gait rehabilitation of the paralyzed people. As its core systems, we developed a variable assist system and an automatic assist adjustment system. The variable assist system based on compliance control can change the stiffness parameter of “Akita Trainer” to provide assist torque according to the degree of paralysis. The automatic assist adjustment system uses reinforcement learning to change the stiffness parameter to the optimal value for the paralyzed people while using this robot. We conducted an experiment with three healthy subjects to validate the combined system of both. We set up two walking patterns: , normal walking and pseudo-hemiplegic walking assuming right hemiplegia. The participants walked for 10 minutes on the treadmill at a speed of 0.8 km/h. The amount of assistance decreased for normal walking and increased for pseudo-hemiplegic walking, indicating that the optimal amount of assistance can be provided according to the walking patterns. By using this system, it is possible to perform gait rehabilitation with the optimal assist torque for the hemiplegic people.

<p><b>Objectives: </b>The extent to which locomotive syndrome is associated with low back pain (LBP), health-related quality of life (HRQOL), and impairment of activities of daily living among elderly men and women remains poorly documented. This study evaluated associations between locomotive syndrome and both HRQOL and LBP as assessed using a questionnaire completed by elderly individuals, including some >80 years old.</p><p><b>Methods: </b>We conducted a survey assessing locomotive syndrome using the loco-check, HRQOL using the Short-Form 36 questionnaire (SF-36), and LBP using the Roland-Morris Disability Questionnaire (RDQ) among individuals >60 years old. SF-36 and RDQ scores were compared between 253 subjects with and without locomotive syndrome.</p><p><b>Results: </b>Fifty-seven men (48%) and 71 women (53%) were diagnosed with locomotive syndrome. Subjects of both sexes with locomotive syndrome scored significantly lower for eight items from SF-36. Physical and mental component summary scores were significantly worse in women with locomotive syndrome in their 60s and 70s. RDQ scores were significantly higher in participants with locomotive syndrome for men in their 60s and for both men and women in their 70s.</p><p><b>Conclusions: </b>Locomotive syndrome was associated with impaired HRQOL and worse LBP among men and women >60 years old. Differences in HRQOL and LBP between subjects with and without locomotive syndrome were significant for both men and women in their 60s and 70s, but not in their 80s. Locomotive syndrome should be prevented to maintain HRQOL, particularly for men and women in their 60s and 70s.</p>

<p>In recent years, gait rehabilitation robots have been developed to reduce the load on paralyzed patients and therapists. The purpose of this study is to design and develop a new gait rehabilitation robot "Akita Trainer" using FES in combination for right hemiplegic, left hemiplegic and paraplegic persons and verification of its control system. The problems of commercially available walking rehabilitation robots were identified, necessary elements were examined, and the items examined were reflected in the design. Then, we have developed main device bearing weight of orthosis, and exoskeleton frames with built-in actuators. In the verification of the control system, the operation of the control system for paraplegics was verified, and the reproducibility of the walking motion was different between the left and right. In the future, we will develop orthoses, complete the Akita Trainer, and verify the operation of that.</p>

<p>脊髄損傷による四肢麻痺・対麻痺では，脳からの運動制御指令が損傷高位で途絶するため末梢に伝達されず，随意的筋収縮ができない状態であることが多い．機能的電気刺激（FES）は，プログラムされた動作刺激を末梢運動神経とその支配筋に行う医用工学的技術で，麻痺からの回復促進や動作再建などに有用である．FESにより，四肢麻痺上肢の手指把持動作再建や，対麻痺起立歩行再建などが可能であり，新しい表面電極FESシステムが国内で普及しつつある．将来的には，多チャンネル同時刺激可能な完全埋め込み電極の実用化，BMIやリハビリテーションロボット技術の発展などと相まって，FESは脊髄損傷再生医療におけるリハビリテーション治療において，重要な役割を担うことが期待される．</p>
