A Construction Method of Lower Limb Rehabilitation Robot with Remote Control System

Abstract

In response to the rehabilitation needs of stroke patients who are unable to benefit from conventional rehabilitation due to the COVID-19 epidemic, this paper designs a robot that combines on-site and telerehabilitation. The objective is to assist the patient in walking. We design the electromechanical system with a gantry mechanism, body-weight support system, information feedback system, and man-machine interactive control system. The proposed rehabilitation robot remote system is based on the client/server (C/S) network framework to realize the remote control of the robot state logic and the transmission of patient training data. Based on the proposed system, doctors can set or adjust the training modes and control the parameters of the robot and guide remote patient rehabilitation training through video communication. The robotic system can further store and manage the rehabilitation data of the patient during training. Experiments show the human-computer interaction system of the lower limb rehabilitation robot has good performance, can accurately recognize the information of human motion posture, and achieve the goal of actively the following motion. Experiments confirm the feasibility of the proposed design, the information management of stroke patients, and the efficiency of rehabilitation training. The proposed system can reduce the workload of the doctors in practical training.

Effectiveness of Physical Therapy Services Through Telemedicine During the Covid-19 Pandemic: Systematic Review

“…From the eight articles reviewed, it is known that physical therapy services through telemedicine or telerehabilitation have produced good results for their users during the Covid-19 pandemic. This method has been successfully applied to patients with cardiorespiratory disorders, patients with musculoskeletal disorders (Patellofemoral Pain Syndrome and breast cancer), as well as patients with neurological disorders (Stroke, and Amyotrophic Lateral Sclerosis) (Albornoz-Cabello et al, 2021;Batalik et al, 2021;De Marchi et al, 2021;Hameed et al, 2021;Lewis et al, 2021;Mella-Abarca et al, 2020;Miao et al, 2021;Turcinovic et…”

“…In addition, it turns out that this method has other advantages. One of them is cost-effective (Batalik et al, 2021;Miao et al, 2021). Telerehabilitation showed to be at least as cost-effective as traditional cardiac rehabilitation programs (Kraal et al, 2014).…”

Research on Intelligent Following Motion Control System of Rehabilitation Robot

“…The system of the rehabilitation robot platform is shown in Figure 1(a). The robot system consists of four parts: multi-sensor, control, weight support and driving systems [21]. Firstly, the user stands in the middle of the rehabilitation robot and wears auxiliary clothes to connect with the rehabilitation robot.…”

Telerehabilitation—A Viable Option for the Recovery of Post-Stroke Patients

“…Strokes are a frequent condition affecting 15 million people every year, of which 5 million survivors live with a consequent disability [1,2]. Healthcare and medical technologies have rapidly evolved in the last years, increasing the survival rate after stroke and therefore raising the number of patients with infirmities [3,4]. Post-stroke patients usually suffer from impaired motor function of one or more limbs, diminished sense of touch, cognition or swallowing alterations and speech and language difficulties [5].…”

“…Teletherapy represents an alternative in the form of a variety of communication technologies, robotic devices or computer games used at home under the remote guidance of the therapist, and is a promising option that can stimulate motivation and prevent boredom [6,8]. Telerehabilitation (TR) implies access anytime and anywhere, through the Internet and technology, to qualitative rehabilitation services of any kind: physiotherapy, occupational therapy, speech and language therapy and neuropsychology [3]. It allows patients to have continuity in the rehabilitation of their acute or chronic conditions in cases of shortage of healthcare staff and medical resources, difficult transport, living in rural areas with difficult access to rehabilitation centers or mobility and interpersonal contact restrictions in the case of a pandemic [18].…”
