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>

		</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

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.
