All of the participants in experimental and comparison groups will practice on the exergaming for 30 minutes per session. To avoid fatigue, the four domains of programs will be provided alternately. Each program will be executed for approximately 5 minutes with warm-up, followed by a 2-minute break between programs, and cool-down. The games will be selected and adapted according to the personal capacity, the occupational role, and the rehabilitation goal of each participant. The investigators will illustrate and guide the participants to play the games and stand next to them to prevent falls from occurring. To increase security, we will place a handrail in front of the participant for support as needed.

Participants in control group will receive 30 minutes of therapist-mediated conventional therapy per session. The training protocols of the conventional therapy will use occupational therapy techniques, such as neurodevelopmental techniques and functional task training. The therapy will be adapted to the participants' levels of motor deficits and their personal needs. The protocol will include affected arm exercise or gross motor training, muscle strengthening of the affected arm, fine motor or dexterity training, and functional tasks of daily life or compensatory techniques to alleviate functional deficits. The content of the functional tasks will be decided together by participants and therapists, such as picking up and putting down items in a box, lifting two soft drink bottles, and so on.

1. The FIM consists of 18 items grouped into 6 sub-scales, including self-care, sphincter control, transfer, locomotion, communication, and social cognition.
2. Each item is rated from 1 (full assistance) to 7 (full independence), according to the level of support required to perform the tasks.
3. A higher score (maximum score of 126) indicates a lower disability.

1. The SSEQ will be used to gauge participants' confidence in their functional performance after stroke.
2. It includes 13 items and gives an overview of the factors that influence functional performance.
3. Each item will be assigned according to the perceived confidence rating on the scale of 0 (no confidence at all) to 10 (full confidence).
4. The higher summed score means the more confidence of participant.

1. Self-reported fatigue and pain severity will be evaluated using the 10-cm vertical line in the Face Rating Scale for adverse effects.
2. The participants will rate the level of their pain and fatigue after the intervention on an 11-point ordinal scale (0 = no pain/fatigue; 10 = the most severe pain/fatigue).
3. The higher score means the more pain or fatigue of participant.
