Participants will undergo traditional occupational therapy (2-3 times per week, one hour per session, for a total of six weeks), supplemented with an additional home-based dynamic orthotic therapy program (five days per week, one hour per session, for six weeks). The style of the dynamic orthosis will be selected by the researchers based on the participants' movement performance and rehabilitation goals, and it will be adjusted or replaced as their abilities progress.

Participants will receive traditional occupational therapy (2-3 sessions per week, one hour per session, for a total of six weeks). The training program includes muscle strength training, reaching and grasping exercises, manual tone control, motor facilitation, and activities of daily living training. During the study period, participants will not wear any hand dynamic orthosis during training.

Engaging in motion training at home with the use of dynamic orthoses.

The Fugl-Meyer Assessment-Upper Extremity (FMA-UE) is a specialized test designed for evaluating motor function in individuals post-stroke. It employs an ordinal scale to score 33 items related to upper limb movements, with a total score of 66 points. Each item reflects movements indicative of motor function in post-stroke hemiparetic patients, covering a range from proximal to distal joints.

The FMA-UE has undergone extensive testing and has been found to possess excellent psychometric properties. It is considered an effective assessment tool for upper limb motor function, particularly suitable for chronic stroke patients with moderate to severe impairments.

The Box and Block Test (BBT) is a tool used to assess manual dexterity, known for its short assessment time, simplicity, and ease of understanding. It exhibits excellent test-retest reliability (0.96) and inter-rater reliability (0.99). The test involves counting the number of cubes a person can move within one minute, with a higher quantity indicating better functionality. The size of the cubes is 2.5cm³, and there are a total of 150 cubes. Past research suggests a Minimal Clinically Important Difference (MCID) value of 5.5 cubes for the BBT.

The Motor Activity Log (MAL) is a questionnaire-based assessment that evaluates the amount of use (AOU) and quality of movement (QOM) of the affected side in daily activities. The scoring for amount of use ranges from 0 (never using the affected hand in the activity) to 5 (always using the affected hand in the activity). Quality of movement is scored from 0 (unable to use the affected hand) to 5 (movement quality comparable to pre-stroke). There are a total of 28 items in the assessment, recording the average scores for both amount of use and movement quality for each item. Previous research has demonstrated good construct validity for this scale, with a Minimal Clinically Important Difference (MCID) ranging from 1.0 to 1.1 points.

The MAS (Modified Ashworth Scale) utilizes quick stretching to assess muscle tone, with testing conducted on the upper limb, specifically the hand, elbow, wrist, and fingers. For ease of statistical analysis, the scale is converted into numerical values ranging from 0 to 5, with lower scores indicating lower muscle tone.
