“…Each dimension includes five items rated on a 5‐point Likert scale (0–4 points), with higher scores indicating more positive ratings. The TSQ‐WT has already been successfully used to evaluate the navigation assistance system of the SW and other robotic devices . It can be adapted to several systems, and was customized to the STS assistance system by deleting the inappropriate dimensions of wearing comfort, which focuses on wearable technology, and privacy and loss of control, which focuses on long‐term technology use.…”

Aim To evaluate the effectiveness and user satisfaction with the sit‐to‐stand (STS) assistance system of a smart walker (SW), and to identify factors associated with them in potential users. Methods A total of 33 older adults (29 women, aged ≥65 years) with motor impairments (habitual rollator use) and no severe cognitive impairment (Mini‐Mental State Examination ≥17 points) carried out a Five‐Chair Stand Test without assistance and five STS transfers with the STS assistance system. Based on the number of successfully completed STS transfers, success rates were calculated for the Five‐Chair Stand Test and the SW‐assisted STS transfers, and compared using the Wilcoxon signed‐rank test. User satisfaction was assessed using the Tele‐healthcare Satisfaction Questionnaire‐Wearable Technology (0–80 points, higher score = higher satisfaction). Bivariate correlations and multiple linear regression analyses were used to identify participant characteristics associated with the success rate and user satisfaction with the STS assistance system. Results The success rate for the SW‐assisted STS transfers was significantly higher than for the Five‐Chair Stand Test (93.3 ± 12.9% vs 54.5 ± 50.6%, P < 0.001). User satisfaction was high (Tele‐healthcare Satisfaction Questionnaire‐Wearable Technology 62.5 ± 11.2 points). The success rate with the STS assistance system was not significantly associated with any participant characteristics. Higher body mass index was a significant independent predictor of higher user satisfaction. Conclusions The SW‐integrated STS assistance system can provide effective STS support with high user satisfaction for a wide range of potential users. Our findings suggest the high potential of the STS assistance system for promoting mobility, independence and quality of life for older adults with motor impairments.

“…The more successful products include BLEEX researched by DARPA [2], Hal-5 made by Cyberdyne [3] and Rewalk [4]. It can be used in medical rehabilitation and some devices [5,6] have already achieved the function of rehabilitation training. But limited by the material, energy, control technology, etc., at present there still has a long distance from the practical application of the robot.…”

Recent years, exoskeleton robot has become the focus of fields of medical rehabilitation, military, aerospace, etc. But there still exist some hardnut problems in the design of mechanism, the movement intention detection and the coupling control of human-machine. Passive control is mainly used for improving the motor recovery of hemiplegic patients. A method of generating bionic trajectories which are used in passive control methods is proposed. Firstly, the structure of the control system of the elbow joint is discussed. Based on the Hill model of skeletal muscle, a new position tracking passive control strategy is proposed, which has a highly similar compliance with human motion. According to the requirements of assistance and comfort, a proportional sliding mode controller is designed using feedback linearization. After that, the model of the control system is simulated, and the tracking characteristics of the angle and angular velocity are analyzed. Finally, the experimental results validate that the passive control strategy has high human similar compliance.

The demand for motor rehabilitation is growing apace with the graying of the population. The utilization of robotic devices in sensorimotor rehabilitation therapy has received increased attention during the last decade. Despite the growing interest in using robotic devices for rehabilitation of sensorimotor function, their widespread use remains somewhat limited by a number of factors, including the assessment of the true cost-to-benefit ratio relative to other types of rehabilitation approaches and parameters that would optimize their long-term efficacy. Understanding human sensorimotor control and brain plasticity can provide insight into the design of robot hardware and controllers with the appropriate reference or desired output. On the other hand, the control of the physical interaction of the therapeutic device with the subject to effectively accelerate recovery is of paramount importance. This special issue focuses on the current state of knowledge about sensorimotor control and brain plasticity, models of sensorimotor functional recovery, and use of intelligent robot controllers to provide robotic-assisted therapy for motor rehabilitation.This special issue includes studies that describe the development, optimization and testing of robotic devices and exoskeletons used for both upper 1,2,9,10,11,12,14,15 and lower limbs. 4,6,8 Methods for quantifying and improving sensorimotor control are also discussed.3,13 The technology and control of hardware physically interfaced with human subjects for rehabilitation is studied providing directions for future applications. 7 Finally, an additional contribution focuses on the use of robots in a social assistive manner for individuals with cerebral palsy. 5Although the studies included here represent the state of the art of robotic systems to be used in sensorimotor rehabilitation, there are several issues that still remain open. It is the opinion of these Guest Editors that the technological advancement in the field of rehabilitation robotics is mature enough to make the transition to the clinic. Actuators with inherently low mechanical impedance provide the necessary safety for these applications. However, how robotic intervention should be tailored to the subject-specific needs remains an open question. More specifically, a model-based approach to robot-assisted therapy is needed. Model-based approaches are successfully used in many engineering fields, and can provide a more controllable and predictable performance. Modelbased therapies are therefore the next big challenge for the field of sensorimotor rehabilitation. Multi-disciplinary teams of researchers with expertise in control, system identification, robotics, neurophysiology, and neuroscience are well positioned to provide the solutions to those challenges in the near future.
