Bilateral training has been shown to normalize intercortical inhibition in stroke patients, facilitate brain functional network reorganization, and ultimately enhance upper limb function21. This study presents a program for upper limb functional training in stroke patients utilizing a dual upper limb task-oriented robotic system. The program integrates bilateral upper limb movement, task-oriented activities, and robot-assisted training to enhance the rehabilitation of upper limb function in stroke...

Stroke is one of the major causes of disability and the second leading cause of death globally1,2. Stroke patients often face various challenges, such as motor, sensory, and cognitive deficits3. Upper limb dysfunction is a common problem after stroke, characterized by muscle weakness, spasticity, and reduced motor ability of the upper limb on the hemiplegic side4. It is reported to be present in more than 70% of stroke patients, and only around 5% recover to normal, while 20% regain some upper limb capabilities5. More than half of human life requires the participation of the upper limbs6, and upper limb dysfunction after a stroke severely affects patients' activities of daily living7, significantly decreasing their quality of life8 and increasing their financial burden9. Therefore, it is particularly important to explore effective methods of upper limb functional rehabilitation.
Various clinical upper limb rehabilitation treatments, such as mirror therapy, constraint-induced movement therapy, functional electrical stimulation, and other active or passive training, are commonly utilized for stroke patients3,10. In recent years, bilateral arm training has garnered increased attention6,11,12. It has been demonstrated to enhance neural connectivity between the sensorimotor areas of both ipsilateral and contralateral hemispheres12. This type of training helps correct abnormalities in interhemispheric inhibition, facilitates reorganization of brain functional networks, and ultimately leads to improvements in upper limb function12,13. Furthermore, robot-assisted training has also been shown to assist patients in consistently executing accurate limb movements and engaging in task-specific training14. This process provides the brain with substantial feedback stimulation, ultimately boosting neuroplasticity and aiding in the restoration of upper limb function in individuals with hemiplegia14,15. There is currently limited research on strategies utilizing robot-assisted dual upper limb training for stroke patients. This study employed a dual upper limb task-oriented robotic system to combine robot-assisted training with bilateral upper limb training. The robotic device was utilized to aid stroke patients in conducting dual upper limb task-oriented training with high repetitions in a proper movement pattern. The objective of the research was to evaluate the effects of this method on the corticospinal pathway, upper-limb function, and activities of daily living in stroke survivors, with the aim of discovering innovative strategies for upper limb functional rehabilitation.

application of a dual upper limb task-oriented robotic system for the functional recovery of the upper limb in stroke patients

Highly repetitive and task-oriented training has been shown to promote the recovery of limb function in stroke patients. Additionally, bilateral arm training can help stroke survivors regain their upper limb function and improve their daily activities. The dual upper limb task-oriented robotic system is designed to assist the healthy side of the stroke patient in driving the affected side to perform bilateral arm training through the use of a robotic device. It can also guide the patient in carrying out dual upper limb coordinated movements and engage them in a task-oriented virtual game using force feedback and human-computer interaction technology. This study aimed to assess the efficacy of the system in enhancing upper limb function and activities of daily living in stroke patients. The assessment methods used included motor evoked potential (MEP), functional test for the hemiplegic upper extremity-Hong Kong (FTHUE-HK), Fugl-Meyer Assessment Upper Extremity Scale (FMA-UE), and modified Barthel index (MBI). The results of the study indicate that the dual upper limb task-oriented robotic system can significantly improve the corticospinal pathway, upper limb function, and activities of daily living in stroke patients after 6 weeks of treatment. This system can serve as an effective adjunct to upper limb functional rehabilitation in stroke survivors, reducing the dependence on rehabilitation therapists. In conclusion, the dual upper limb task-oriented robotic system provides a new strategy for post-stroke limb functional rehabilitation and holds great potential for application, as it offers certain social and financial benefits.

Application of a Dual Upper Limb Task-Oriented Robotic System for the Functional Recovery of the Upper Limb in Stroke Patients

Our research is focused on the rehabilitation of patients who have suffered a stroke or traumatic brain injury, and we're trying to investigate the impact of our robot-assisted to upper limb training strategy on the recovery of upper limb function in stroke patients. Our protocol integrates bilateral upper limb training, task-oriented activities, and robot-assisted training to enhance the rehabilitation of upper limb function in stroke patients. We will focus on the impact of neuromodulation technology, virtual reality technology, and artificial intelligence robotic assistants on post-stroke limb function rehabilitation.

A total of 60 stroke patients were divided into a control group (n = 30) and an experimental group (n = 30) for this study. Upon comparing age, gender, stroke type, disease duration, side of hemiplegia, and other general information between the two groups, no statistically significant differences were found (P &#62; 0.05), indicating their comparability (Table 1). Patients in the experimental group, who underwent training with a dual upper limb task-oriented robotic system, showed greater improvements in...
