“…Some authors have also proposed works on the linear actuator applied in equipment to support lower limb rehabilitation exercises. [24][25][26][27][28] In these papers, the authors also introduced some mathematical models for the linear actuator, but these mathematical models are not specific and do not consider the impact force of the patient's lower-extremity joints.…”

In recent years, the number of stroke patients has increased, which has led to an increased need for motor rehabilitation exercises. The application of automation devices in the rehabilitation of patients is becoming increasingly developed. These devices help reduce the patient training time and workload. Each type of equipment uses different actuators such as electric motors, pneumatic cylinders, and hydraulic cylinders. Different from previous studies, in this paper, a research model of lower extremity rehabilitation devices using a simple actuator which is a linear actuator is presented. The main contribution of this study is that a dynamic model of the linear actuator associated with the action dynamics of the lower extremities of the studied model with three degrees of freedom was established. A mathematical model for this actuator is also presented, simulating the response of the mechanism using the MATLAB/Simulink software. A lower extremity rehabilitation device using a linear actuator was manufactured and tested. The test results for 10 volunteers show that the actuator works and causes miniature angle errors. This experiment demonstrates that the linear actuator can be used in stroke patient rehabilitation equipment and contributes to the diversification of the mechanism in automation equipment.

In this study, an active exercise function was added to a continuous passive motion device, which is widely used in rehabilitation therapy for function enhancement. The objective is to reduce physical overwork on the part of physical therapists and promote self-rehabilitation in patients. Impedance control based on position control was applied to provide active exercise load. Various active exercise loads are required to reproduce daily life muscle activity. Accordingly, a friction load model was introduced in the impedance control system. The effects of increasing the types of active exercise loads were evaluated by analysis of muscle activity during experimental tests, and a new muscle activity that could not be attained by the conventional spring-mass-damper load model was confirmed.

Over the last few years, numerous robotic ankle-foot orthoses have been developed to help stroke patients optimize gait rehabilitation. In this paper, we present a study on the effects of assistance on dorsiflexion-restricted gait. Our high-dorsiflexion assistive system aims to provide full assistance to realize passive training of dorsiflexion during the swing phase and prevent compensatory movements. This system, which includes a McKibben-type artificial muscle and an air source, is lightweight and provides a high-dorsiflexion torque. The device could help boost overground gait rehabilitation in stroke patients. With this system, we conducted an experiment on five healthy participants whose dorsiflexion movements were restricted, and the extent of their compensatory movements differed. The results of the processed surface electromyography data differed significantly when dorsiflexion movement was assisted by our system. The spatial parameters also showed significantly improved compensatory movement inclination with sufficient assistance. These results indicate the potential of our system to assist in passive training of ankle dorsiflexion movements and to prevent incorrect gait in patients with low dorsiflexion abilities.
