“…ASIA scores did not show relevant changes for either group (Figure 1B ). The improvements suggested possibility of beneficial effect of HAL for OPLL patients as previous studies (Aach et al, 2014 ; Fujii et al, 2016 ; Kasai and Takeda, 2016 ; Kubota et al, 2016 ). The effect of HAL therapy could be a reinforcement of the motor learning process during training, helping patients to reshape their motor function.…”

“…In previous studies where HAL was used in neurologic patients with gait disturbances, improvement in clinical scores, and walking performance, such as elongation of the stride length and increment of gait speed, was found (Kawamoto et al, 2013 ; Sakakima et al, 2013 ; Fujii et al, 2016 ; Kubota et al, 2016 ; Sczesny-Kaiser et al, 2017 ). A group of stroke patients treated with HAL improved their sit-to-stand movements thanks to the increment of the forward tilt angle (Kasai and Takeda, 2016 ). Additionally, spinal cord injury patients showed improvement in their spasticity (Ikumi et al, 2016 ), recovery of lower limb muscle activities (Shimizu et al, 2017 ), reduction of neuropathic pain (Cruciger et al, 2016 ) and normalization of cortical excitability and cortical plasticity (Sczesny-Kaiser et al, 2017 ).…”

Reshaping of Gait Coordination by Robotic Intervention in Myelopathy Patients After Surgery

The Ossification of the Posterior Longitudinal Ligament (OPLL) is an idiopathic degenerative spinal disease which may cause motor deficit. For patients presenting myelopathy or severe stenosis, surgical decompression is the treatment of choice; however, despite adequate decompression residual motor impairment is found in some cases. After surgery, there is no therapeutic approach available for this population. The Hybrid Assistive Limb® (HAL) robot suit is a unique powered exoskeleton designed to predict, support, and enhance the lower extremities performance of patients using their own bioelectric signals. This approach has been used for spinal cord injury and stroke patients where the walking performance improved. However, there is no available data about gait kinematics evaluation after HAL therapy. Here we analyze the effect of HAL therapy in OPLL patients in acute and chronic stages after decompression surgery. We found that HAL therapy improved the walking performance for both groups. Interestingly, kinematics evaluation by the analysis of the elevation angles of the thigh, shank, and foot by using a principal component analysis showed that planar covariation, plane orientation, and movement range evaluation improved for acute patients suggesting an improvement in gait coordination. Being the first study performing kinematics analysis after HAL therapy, our results suggest that HAL improved the gait coordination of acute patients by supporting the relearning process and therefore reshaping their gait pattern.

Background and aims There is a growing demand for health and social care services to provide technology‐mediated interventions that promote the health and well‐being of older people with health or care needs and of their informal carers. The objectives of this study were to scope and review the nature and extent of prior intervention studies involving ambient assisted living technology‐mediated interventions for older people and their informal carers, and how and in what ways (if any) the goals and aims of these interventions reflected the domains of the World Health Organization framework for healthy ageing. Methods We conducted a scoping review. Data were collected between June and October 2018 with an updated search in October 2020. A total of 85 articles were eligible for inclusion. Results Nine categories described the aims and content of the included studies. The healthy ageing domain “Ability to meet basic needs” was mirrored in four categories, whereas “Ability to contribute to society” was not addressed at all. Conclusion The ways in which domains of healthy ageing are mirrored suggest that there is an emphasis on individual factors and individual responsibility, and a lack of attention given to broader, environmental factors affecting healthy ageing. Only a few of the studies used a dyadic approach when assessing health outcomes concerning older people and their informal carers.

“…In stroke patients with spasticity or motor paralysis, it is possible to follow functional changes by using EMG to clarify characteristics of standing and standing-up in hemiplegic stroke patients [7][8][9][10]. It is also possible to observe characteristics of posture in those with Parkinson's disease via EMG [11].…”

Objective: For the convenient use of electromyography devices in physical rehabilitation during locomotion, we developed a simple, low-cost 2-channel electromyography telemeter (LC-EMGT) that can be connected wirelessly with a personal computer (PC) microphone port.The aim of this study was to verify whether the performance of our LC-EMGT fulfills the need for monitoring EMG during locomotion of patients in rehabilitation. For this purpose, we compared the performance of our LC-EMGT with an existing EMG device (NeuropackΣ). Methods:Muscle activity of the left and right vastus medialis were recorded when the participant repeated a standing-up movement for 10 seconds at 55-bpm speed. The EMG signal was simultaneously recorded by the LC-EMGT and NeuropackΣ. We compared the waveform of these EMG signals and their root mean squared signals in appearance and by cross-correlation analysis. Also, we monitored the orthopedic patients' EMG waveforms during standing-up and ascending stairs. Results:The cross-correlation analysis demonstrated an approximately 170-ms delay in EMG measurement by LC-EMGT due to the wireless signal transformation. Meanwhile, the amplitudes of the waveforms in the LC-EMGT were almost equal to those of the NeuropackΣ. In addition, with the LC-EMGT, we could visually monitor EMG waveforms of the patients during standing-up and stair climbing on-line using a PC. Conclusion:Consequently, the LC-EMGT was as reliable as the existing EMG device at monitoring EMG signals and is available as an EMG monitor in real-time. The LC-EMGT is cost-effective, convenient, and may be generally used in various clinical and sports situations.
