We thank the patients and healthcare staff of the First Affiliated Hospital of Zhejiang University School of Medicine for their support and cooperation throughout this study.

This study protocol received approval from the ethics committee of the First Affiliated Hospital of Zhejiang University (approval number IIT20210035C-R2), and informed consent was obtained from all participants. An experimental study employing quasi-randomization, single-blinding, and a control group was conducted to assess the feasibility and effectiveness of the program. 24 patients hospitalized in the rehabilitation medicine ward of the First Affiliated Hospital of Zhejiang University were invited to participate in this experiment. Inclusion criteria encompassed stroke patients confirmed by computed tomography (CT) or magnetic resonance imaging (MRI), aged 30-75 years, 6-24 weeks post-stroke, a Montreal Cognitive Rating Scale (MoCA) score &#60;2613, upper limb dysfunction14, unilateral hemiplegia, Brunnstrom stage 3-6 for sitting ability15, and cooperation for assessment and treatment. Exclusion criteria included a history of cognitive disorders, major organ dysfunction, visual or hearing impairment, abnormal mental behavior or antipsychotic drug use, severe spasticity (Ashworth scale 3-4)16, and shoulder subluxation or severe upper limb pain.
1. Study design
<ol>
	<li>Divide all the patients into the control group and the experimental group (12 in each group) according to the random number table method2. 
	NOTE: Before the experiment, the following assessments were completed by an experienced occupational therapist for all patients: The Montreal Cognitive Assessment (MoCA)13, Fugl-Meyer Assessment Upper Extremity Scale (FMA-UE)14, and Modified Barthel Index (MBI)17.</li>
	<li>Verify and confirm that patients in the experimental group underwent conventional drug therapy, including medications for antihypertensives, antidiabetics, antiplatelets, lipid-regulating agents, etc., as prescribed by their respective physicians.
	<ol>
		<li>Additionally, ensure that they received 30 min of routine occupational therapy training each day, comprising cognitive function training and upper limb function training. Furthermore, confirm that they dedicated 30 min daily to the digital occupational training system for a duration of 8 weeks. 
		NOTE: The term &#34;conventional drug therapy&#34; refers to standard medications prescribed for post-stroke care, and the specific medications may vary among patients and clinics.</li>
	</ol>
	</li>
	<li>Ensure that patients in the control group receive routine occupational therapy (OT) for 1 h each day, in conjunction with conventional drug therapy.</li>
	<li>Implement routine cognitive function training tailored to the types of patients&#39; cognitive impairment following the steps below: 
	NOTE: Both control and experimental group of patients receive these trainings.
	<ol>
		<li>For Memory dysfunction: Guide patients to engage in activities such as discussing pictures, reciting paragraphs, path memory exercises, and recalling life plots.</li>
		<li>For Attention dysfunction: Instruct patients to participate in eye tracking training, number classification exercises, and similar picture recognition training.</li>
		<li>For Dyscalculia: Request patients to perform simple addition and subtraction exercises involving numbers less than 50, along with activities like shopping and financial simulation training.</li>
		<li>For Visuospatial disturbance: Guide patients through activities such as stacking wood, solving jigsaw puzzles, drawing, and turning objects.</li>
		<li>For Executive dysfunction: Lead patients in activities like origami, hand-making, painting, watering flowers, and others.</li>
		<li>For Thinking and reasoning dysfunction: Guide patients in classifying items, arranging numbers, simulating supermarket shopping, progressing from general reasoning to specific reasoning.</li>
	</ol>
	</li>
	<li>Instruct patients to engage in conventional upper limb functional exercises, encompassing passive and dominant movements of each joint of the upper limb. This includes activities like roller training, upper limb extraction, throwing and catching the ball, and control training for shoulder, elbow, and wrist movements.
	<ol>
		<li>Additionally, include forearm pronation and supination, finger fine movements, and coordination flexibility training, such as using a pin board and screw screwing. 
		NOTE: Dressing and stripping training, self-help equipment application, and other exercises to enhance the ability of daily living activities should primarily focus on the affected side, with appropriate incorporation of the healthy side to assist in the training of the affected side. All experimental steps are conducted in the rehabilitation room of the ward. The mentioned training is carried out 5 days a week for a duration of 8 weeks.</li>
	</ol>

			<li>Object Differentiation Training: Among several columns of shapes appearing on the screen, ask the patients to identify and click the one that is unique and different from the others.</li>
		</ol>
		</li>
	</ol>
	</li>
	<li>Conduct Upper limb functional training.
	<ol>
		<li>Train the patients with Auxiliary exercises or one-handed exercises. 
		NOTE: If the affected limb is unable to complete the training alone, have the healthy hand hold the affected limb and complete auxiliary training. Once the affected limb regains a certain level of muscle strength, one-handed training can be initiated. The following training procedures are suitable for auxiliary exercises or one-handed exercises: &#34;Drawing Exercise,&#34; &#34;Musical Journey,&#34; &#34;Walking The Maze.&#34;
		<ol>
			<li>Drawing Exercise: According to the path prompts appearing on the screen, instruct the patients to draw specific lines or outlines of the pattern. The system will automatically generate a beautiful picture. As the difficulty increases, consider allowing the path to disappear and ask the patient to outline the picture from memory.</li>
			<li>Musical Journey: Have the patient erase gray squares on the screen in sync with the rhythm of the music, transforming them into colorful squares. This provides an intensely pleasurable experience.</li>
			<li>Walking The Maze: Instruct the patient to hold onto the small ball in the maze and guide the ball through the maze to reach the endpoint where the diamond is located.</li>
		</ol>
		</li>
		<li>Train the patients with Two-handed coordination exercises. 
		NOTE: If the affected limb has good muscle strength, two-hand coordination training can be initiated. Choose procedures such as &#34;Balance Ball,&#34; &#34;Fish Feeding Game,&#34; &#34;Archery Practice,&#34; and &#34;Reaction Coordination Training.&#34;
		<ol>
			<li>Balance Ball: Have the patient place their left and right fists on both ends of the balance beam, which has a small blue ball on it. Instruct them to maintain balance and prevent the ball from rolling off either side.</li>
			<li>Fish Feeding Game: Instruct patients to hold down the feed with one hand and click on the small fish swimming on the screen with the other hand to complete the fish feeding task.</li>
			<li>Archery Practice: Guide the patient to place one hand on the bow and the other on the arrow, clicking and controlling the arrow so that it hits the bull&#39;s eye perfectly.</li>
			<li>Reaction Coordination Training: Let the right and left hands of the patients hold down the hammer and click to hit the yellow ball alternately, similar to the game of ping-pong, to train the patient&#39;s coordination and reaction ability. 
			NOTE: Upon the completion of training for each procedure, the instrument automatically provides an analysis of the training results, storing them in the patient&#39;s exclusive file. The therapist evaluates the patient&#39;s training effect by comparing the results each time (Figure 3 and Figure 4).</li>
		</ol>
		</li>
	</ol>
	</li>
	<li>As the patient&#39;s function recovers, ask the therapist to regularly recombine the training program, adjusting the difficulty and duration of the procedure based on the patient&#39;s performance. 
	NOTE: Throughout the training period, the therapist supervises the entire training process of the patient, patiently listens to the patient&#39;s needs, assists the patient when encountering difficulties, and offers praise and encouragement upon successful completion of training tasks.</li>
</ol>
3. Follow up procedures
<ol>
	<li>Following 8 weeks of treatment, conduct a reassessment of all patients using the MoCA, FMA-UE, and MBI. This reassessment is carried out by the same occupational therapist.</li>
	<li>Statistically analyze the collected data from the pre- and post-training assessments to determine the significance of the outcomes. 
	NOTE: Appropriate statistical methods were employed, depending on the normality of the data distribution, to assess the impact of the digital occupational training system on the recovery of cognitive and motor functions.</li>

There is a high incidence, mortality, disability rate, and recurrence associated with stroke, or cerebrovascular accident1. Globally, stroke has surpassed tumors and heart disease to become the second leading cause of death, and it is the primary cause in China2. The incidence and social burden of stroke are expected to increase significantly in the coming years as the population ages. Survivors of stroke may continue to experience sensory, motor, cognitive, and psychological impairments3. The effects of a stroke can include paralysis of one side of the body, including the face, arms, and legs, a condition known as hemiplegia. This is the most common sequel to stroke and significantly impacts people's quality of life4.
Stroke poses a significant threat to people's health. Due to brain tissue damage, stroke and hemiplegia can result in hand dysfunction, hindering patients' activities of daily living (ADLs) and diminishing their quality of life5. Decreased upper limb function, especially of the hands as the distal body part, presents the most significant challenge in upper limb recovery6. Therefore, functional rehabilitation is crucial. Additionally, 20%-80% of stroke patients experience cognitive impairment, leading to deficits in attention, memory, language, and executive abilities7.
Currently, the clinical rehabilitation of upper limb hemiplegia primarily relies on comprehensive upper limb training and various occupational therapies (e.g., mirror box treatment8, suspension9, functional electrical stimulation10, among others). Recently, virtual reality and interactive video games have emerged as alternative rehabilitation methods. These interventions can facilitate high-capacity practice and reduce demands on therapists' time11. Virtual reality systems have rapidly evolved into new commercial devices that can be utilized to enhance cognitive and upper limb motor function in stroke survivors12. Despite these advancements, there are still unexplored avenues in this field.
Therefore, this study aims to investigate the effects of upper limb rehabilitation training combined with conventional upper limb rehabilitation on cognitive and upper limb motor function in stroke patients during the recovery period of hemiparesis, typically spanning the initial 6-24 weeks after the incident stroke. Additionally, we will examine its impact on daily life abilities. This research seeks to provide valuable evidence for the clinical application of robotic interventions.

cognitive function and upper limb rehabilitation training post-stroke using a digital occupational training system

Stroke rehabilitation often requires frequent and intensive therapy to improve functional recovery. Virtual reality (VR) technology has shown the potential to meet these demands by providing engaging and motivating therapy options. The digital occupational training system is a VR application that utilizes cutting-edge technologies, including multi-touch screens, virtual reality, and human-computer interaction, to offer diverse training techniques for advanced cognitive capacity and hand-eye coordination abilities. The objective of this study was to assess the effectiveness of this program in enhancing cognitive function and upper extremity rehabilitation in stroke patients. The training and assessment consist of five cognitive modules covering perception, attention, memory, logical reasoning, and calculation, along with hand-eye coordination training. This research indicates that after eight weeks of training, the digital occupational training system can significantly improve cognitive function, daily living skills, attention, and self-care abilities in stroke patients. This software can be employed as a time-saving and clinically effective rehabilitation aid to complement traditional one-on-one occupational therapy sessions. In summary, the digital occupational training system shows promise and offers potential financial benefits as a tool to support the functional recovery of stroke patients.

In this study, 24 patients were enrolled presenting with upper limb dysfunction combined with various types of cognitive impairment following a stroke. The observed types of cognitive impairment included Amnesia, Agnosia, Executive Dysfunction, Attentional Impairments, among others. No statistically significant differences were found between the two groups in terms of sex, age, duration of disease, and type of stroke (P &#62; 0.05), as detailed in Table 1. The experimental group, which underwent...

An Investigation of the Effects of Sports-related Concussion in Youth Using Functional Magnetic Resonance Imaging and the Head Impact Telemetry System

One of the most commonly reported injuries in children who participate in sports is concussion or mild traumatic brain injury (mTBI)1. Children and youth involved in organized sports such as competitive hockey are nearly six times more likely to suffer a severe concussion compared to children involved in other leisure physical activities2. While the most common cognitive sequelae of mTBI appear similar for children and adults, the recovery profile and breadth of consequences in children remains largely unknown2, as does the influence of pre-injury characteristics (e.g. gender) and injury details (e.g. magnitude and direction of impact) on long-term outcomes. Competitive sports, such as hockey, allow the rare opportunity to utilize a pre-post design to obtain pre-injury data before concussion occurs on youth characteristics and functioning and to relate this to outcome following injury. Our primary goals are to refine pediatric concussion diagnosis and management based on research evidence that is specific to children and youth. To do this we use new, multi-modal and integrative approaches that will:
 1.Evaluate the immediate effects of head trauma in youth 
2.Monitor the resolution of post-concussion symptoms (PCS) and cognitive performance during recovery 
3.Utilize new methods to verify brain injury and recovery
To achieve our goals, we have implemented the Head Impact Telemetry (HIT) System. (Simbex; Lebanon, NH, USA). This system equips commercially available Easton S9 hockey helmets (Easton-Bell Sports; Van Nuys, CA, USA) with single-axis accelerometers designed to measure real-time head accelerations during contact sport participation 3 - 5. By using telemetric technology, the magnitude of acceleration and location of all head impacts during sport participation can be objectively detected and recorded. We also use functional magnetic resonance imaging (fMRI) to localize and assess changes in neural activity specifically in the medial temporal and frontal lobes during the performance of cognitive tasks, since those are the cerebral regions most sensitive to concussive head injury 6. Finally, we are acquiring structural imaging data sensitive to damage in brain white matter.

This article provides an overview of a multi-modal approach to mild traumatic brain injury diagnosis and recovery in youth. This approach combines neuropsychological testing with functional magnetic resonance imaging and the Head Impact Telemetry System to monitor the relationship between head impacts and brain activity during cognitive testing.

A Murine Model of Muscle Training by Neuromuscular Electrical Stimulation

Neuromuscular electrical stimulation (NMES) is a common clinical modality that is widely used to restore1, maintain2 or enhance3-5 muscle functional capacity. Transcutaneous surface stimulation of skeletal muscle involves a current flow between a cathode and an anode, thereby inducing excitement of the motor unit and the surrounding muscle fibers. 
NMES is an attractive modality to evaluate skeletal muscle adaptive responses for several reasons. First, it provides a reproducible experimental model in which physiological adaptations, such as myofiber hypertophy and muscle strengthening6, angiogenesis7-9, growth factor secretion9-11, and muscle precursor cell activation12 are well documented. Such physiological responses may be carefully titrated using different parameters of stimulation (for Cochrane review, see 13). In addition, NMES recruits motor units non-selectively, and in a spatially fixed and temporally synchronous manner14, offering the advantage of exerting a treatment effect on all fibers, regardless of fiber type. Although there are specified contraindications to NMES in clinical populations, including peripheral venous disorders or malignancy, for example, NMES is safe and feasible, even for those who are ill and/or bedridden and for populations in which rigorous exercise may be challenging. 
Here, we demonstrate the protocol for adapting commercially available electrodes and performing a NMES protocol using a murine model. This animal model has the advantage of utilizing a clinically available device and providing instant feedback regarding positioning of the electrode to elicit the desired muscle contractile effect. For the purpose of this manuscript, we will describe the protocol for muscle stimulation of the anterior compartment muscles of a mouse hindlimb.

A murine model of neuromuscular electrical stimulation (NMES), a safe and inexpensive clinical modality, to the anterior compartment muscles is described. This model has the advantage of modifying a readily available clinical device for the purpose of eliciting targeted and specific muscle contractions in mice.

A Multi-Modal Approach to Assessing Recovery in Youth Athletes Following Concussion

Concussion is one of the most commonly reported injuries amongst children and youth involved in sport participation. Following a concussion, youth can experience a range of short and long term neurobehavioral symptoms (somatic, cognitive and emotional/behavioral) that can have a significant impact on one&#8217;s participation in daily activities and pursuits of interest (e.g., school, sports, work, family/social life, etc.). Despite this, there remains a paucity in clinically driven research aimed specifically at exploring concussion within the youth sport population, and more specifically, multi-modal approaches to measuring recovery. This article provides an overview of a novel and multi-modal approach to measuring recovery amongst youth athletes following concussion. The presented approach involves the use of both pre-injury/baseline testing and post-injury/follow-up testing to assess performance across a wide variety of domains (post-concussion symptoms, cognition, balance, strength, agility/motor skills and resting state heart rate variability). The goal of this research is to gain a more objective and accurate understanding of recovery following concussion in youth athletes (ages 10-18 years). Findings from this research can help to inform the development and use of improved approaches to concussion management and rehabilitation specific to the youth sport community.

Adapted Resistance Training Improves Strength in Eight Weeks in Individuals with Multiple Sclerosis

Hip weakness is a common symptom affecting walking ability in people with multiple sclerosis (MS). It is known that resistance strength training (RST) can improve strength in individuals with MS, however; it remains unclear the duration of RST that is needed to make strength gains and how to adapt hip strengthening exercises for individuals of varying strength using only resistance bands. This paper describes the methodology to set up and implement an adapted resistance strength training program, using resistance bands, for individuals with MS. Directions for pre- and post-strength tests to evaluate efficacy of the strength-training program are included. Safety features and detailed instructions outline the weekly program content and progression. Current evidence is presented showing that significant strength gains can be made within 8 weeks of starting a RST program. Evidence is also presented showing that resistance strength training can be successfully adapted for individuals with MS of varying strength with little equipment.

Hip weakness is a common symptom affecting walking ability in people with multiple sclerosis. Isolated muscle strengthening is a useful method to target specific weaknesses. This protocol describes a progressive resistance-training program using exercise bands to increase hip muscle strength.

A Method for Quantifying Upper Limb Performance in Daily Life Using Accelerometers

A key reason for referral to rehabilitation services after stroke and other neurological conditions is to improve one's ability to function in daily life. It has become important to measure a person's activities in daily life, and not just measure their capacity for activity in the structured environment of a clinic or laboratory. A wearable sensor that is now enabling measurement of daily movement is the accelerometer. Accelerometers are commercially-available devices resembling large wrist watches that can be worn throughout the day. Data from accelerometers can quantify how the limbs are engaged to perform activities in peoples' homes and communities. This report describes a methodology to collect accelerometry data and turn it into clinically-relevant information. First, data are collected by having the participant wear two accelerometers (one on each wrist) for 24 h or longer. The accelerometry data are then downloaded and processed to produce four different variables that describe key aspects of upper limb activity in daily life: hours of use, use ratio, magnitude ratio, and the bilateral magnitude. Density plots can be constructed that visually represent the data from the 24 h wearing period. The variables and their resultant density plots are highly consistent in neurologically-intact, community-dwelling adults. This striking consistency makes them a useful tool for determining if upper limb daily performance is different from normal. This methodology is appropriate for research studies investigating upper limb dysfunction and interventions designed to improve upper limb performance in daily life in people with stroke and other patient populations. Because of its relative simplicity, it may not be long before it is also incorporated in clinical neurorehabilitation practice.

This protocol describes a method to quantify upper limb performance in daily life using wrist-worn accelerometers.

Porcine As a Training Module for Head and Neck Microvascular Reconstruction

Live models that resemble surgical conditions of humans are needed for training free-flap harvesting and anastomosis. Animal models for training purposes have been available for years in many surgical fields. We used the female (because they are easy to handle for the procedure) Yorkshire pigs for the head and neck reconstruction by harvesting the deep inferior epigastric artery perforator or the superior epigastric artery perforator flap. The anastomosis site (neck skin defect or tracheal wall defect) was prepared via the dissection of the common carotid artery and the internal jugular vein, in which 3.5&#215; loupe magnification was used for anastomosis as we use on human cases in real life. This procedure demonstrates a new training method using a reliable learning model and provides a detailed anatomy in a live scenario. We focused on the ischemia time, harvesting, vessel anastomosis, and designing the flap to fit the defect site. This model improves tissue handling and with the use of proper instruments can be repeated many times so that the surgeon is fully confident before starting the surgery on humans.

Here we present a protocol for the use of the pig superior epigastric artery perforator flap as a learning module for head and neck microvascular reconstruction.

Autonomic Function Following Concussion in Youth Athletes: An Exploration of Heart Rate Variability Using 24-hour Recording Methodology

Participation in organized sports makes a significant contribution to youth development, but places youth at a higher risk for sustaining a concussion. To date, return-to-activity decision-making has been anchored in the monitoring of self-reported concussion symptoms and neurocognitive testing. However, multi-modal assessments that corroborate objective physiological measures with traditional subjective symptom reporting are needed and can be valuable. Heart rate variability (HRV) is a non-invasive physiological indicator of the autonomic nervous system, capturing the reciprocal interplay between the sympathetic and parasympathetic nervous systems. There is a dearth of literature exploring the effect of concussion on HRV in youth athletes, and developmental differences preclude the application of adult findings to a pediatric population. Further, the current state of HRV methodology has primarily included short-term (5-15 min) recordings, by using resting state or short-term physical exertion testing to elucidate changes following concussion. The novelty in utilizing a 24 h&#160;recording methodology is that it has the potential to capture natural variation in autonomic function, directly related to the activities a youth athlete performs on a regular basis. Within a prospective, longitudinal research setting, this novel approach to quantifying autonomic function can provide important information regarding the recovery trajectory, alongside traditional self-report symptom measures. Our objectives regarding a 24 h recording methodology were to (1) evaluate the physiological effects of a concussion in youth athletes, and (2) describe the trajectory of physiological change, while considering the resolution of self-reported post-concussion symptoms. To achieve these objectives, non-invasive sensor technology was implemented. The raw beat-to-beat time intervals captured can be transformed to derive time domain and frequency domain measures, which reflect an individual&#39;s ability to adapt and be flexible to their ever-changing environment. By using non-invasive heart rate technology, autonomic function can be quantified outside of a traditional controlled research setting.

We demonstrate a 24 h heart rate recording methodology to evaluate the influence of concussion across the recovery trajectory in youth athletes, within an ecologically valid context.

Development of a Novel Task-oriented Rehabilitation Program using a Bimanual Exoskeleton Robotic Hand

A robot-assisted hand is used for the rehabilitation of patients with impaired upper limb function, particularly for stroke patients with a loss of motor control. However, it is unclear how conventional occupational training strategies can be applied to the use of rehabilitation robots. Novel robotic technologies and occupational therapy concepts are used to develop a protocol that allows patients with impaired upper limb function to grasp objects using their affected hand through a variety of pinching and grasping functions. To conduct this appropriately, we used five types of objects: a peg, a rectangular cube, a cube, a ball, and a cylindrical bar. We also equipped the patients with a robotic hand, the Mirror Hand, an exoskeleton&#160;hand that is fitted to the subject&#8217;s affected hand and follows the movement of the sensor glove fitted to their unaffected hand (bimanual movement training (BMT)). This study had two stages. Three healthy subjects were first recruited to test the feasibility and acceptability of the training program. Three patients with hand dysfunction caused by stroke were then recruited to confirm the feasibility and acceptability of the training program, which was conducted on 3 consecutive days. On each day, the patient was monitored during 5 min of movement in a passive range of motion, 5 min of robot-assisted bimanual movement, and task-oriented training using the five objects. The results showed that both healthy subjects and subjects who had suffered a stroke in conjunction with the robotic hand could successfully grasp the objects. Both healthy subjects and those who had suffered a stroke performed well with the robot-assisted task-oriented training program in terms of feasibility and acceptability.

This study reports the development of a novel robot-assisted task-oriented program for hand rehabilitation. The developmental process consists of experiments using both healthy subjects and subjects who have had a stroke and suffered from subsequent motor control dysfunction.

Integrated Robotic and Conventional Therapy for Post-Stroke Upper Limb Recovery

Enhancing Upper Limb Function and Motor Skills Post-Stroke Through an Upper Limb Rehabilitation Robot

Cerebrovascular accidents, commonly known as strokes, represent a prevalent neurological event leading to significant upper limb disabilities, thereby profoundly affecting individuals' activities of daily living and diminishing their quality of life. Traditional rehabilitation methods for upper limb recovery post-stroke are often hindered by limitations, including therapist and patient fatigue, reliance on singular training methodologies, and lack of sustained motivation. Addressing these challenges, this study introduces an upper limb rehabilitation robot, which uses intelligent feedback motion control to improve therapeutic outcomes. The system is distinguished by its capability to adjust the direction and magnitude of force feedback dynamically, based on the detection of spastic movements during exercises, thereby offering a tailored therapeutic experience. This system is equipped with four distinct training modes, intelligent assessment of joint range of motion, and the ability to personalize training programs. Moreover, it provides an immersive interactive gaming experience coupled with comprehensive safety measures. This multifaceted approach not only elevates the engagement and interest of participants beyond traditional rehabilitation protocols but also demonstrates significant improvements in upper limb functionality and the activities of daily living among hemiplegic patients. The system exemplifies an advanced tool in upper limb rehabilitation, offering a synergistic blend of precision, personalization, and interactive engagement, thereby broadening the therapeutic options available to stroke survivors.

Dual Upper Limb Robotic Training in Stroke 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.
