Exclusion Criteria:
The participants will received 2 weeks of RT therapy and followed by 2 weeks of distributed CIT therapy. The treatment principles of RT and distributed CIT are the same with those described in the monotherapy of RT or dCIT, respectively.
Behavioral: RT in sequential combination with dCIT
The dCIT group will focus on restriction on movement of the unaffected hand by placement of the hand in a mitt for 6 hours/day and intensive training of the affected UL in functional tasks for 1.5 hours/weekday over the 4 weeks. Participants in this group will focus on the intensive training of the affected arm in functional activities with behavioral shaping.
Behavioral: Distributed Constraint-Induced Therapy
Participants will receive 20 training sessions (1.5 hours/day, 5 days/week for 4 consecutive weeks). The ArmeoSpring will be used in this project. It is a 5 degree-of-freedom skeleton mechanism that automates arm movement in a gravity-supported and computer-enhanced environment. The design of the arm support component of the ArmeoSpring is based on Wilmington Robotic Exoskeleton, an antigravity arm support. Instrumentation of the ArmeoSpring with position sensors at each joint enables it to be used as a 3D input device for computer game play with the hemiparetic arm. A custom software package named Vu Therapy will be also used in this project. Games were designed to simulate functional arm movements to provide training in a simple virtual reality environment.
Behavioral: Robot-Assisted Therapy
Participants will receive 20 training sessions (1.5 hours/day, 5 days/week for 4 consecutive weeks). This group will received a structured protocol using conventional occupational therapy techniques such as neuro-developmental techniques with emphasis on functional tasks and muscle strengthening. The treatment protocol will include (1) passive range of motion exercises, stretching of the affected limb, or facilitatory and inhibitory techniques for 15 to 20 minutes, (2) fine motor or dexterity training for 20 minutes, (3) arm exercises or gross motor training for 20 minutes, (4) muscle strengthening of the affected upper limb for 15 to 20 minutes, and (5) activities of daily living or functional tasks training for 15 to 20 minutes.
Behavioral: Dose-matched control therapy
The participants will received 2 weeks of RT therapy using the ArmeoSpring and followed by 2 weeks of distributed CIT therapy. The treatment principles of RT and distributed CIT are the same with those described in the monotherapy of RT or dCIT, respectively.

Fugl-Meyer Assessment (FMA)
The upper-extremity subscale of the FMA will be used to assess motor impairment. The 33 upper limb items measure the movement and reflexes of the shoulder/elbow/forearm, wrist, hand, and coordination/speed. They are scored on a 3-point ordinal scale (0-cannot perform, 1-performs partially, 2-performs fully). The maximum score is 66, indicating optimal recovery.
Time frame: An expected average of 4 weeks
Functional Independence Measure (FIM)
The FIM consists of 18 items grouped into 6 subscales measuring self-care, sphincter control, transfer, locomotion, communication, and social cognition ability. Each item is rated from 1 to 7 (maximum score 126) based on the required level of assistance to perform the tasks (e.g., 1-complete assistance and 7-complete independence). A higher score on any subscale indicates a less disability.
Time frame: An expected average of 4 weeks
Stroke Impact Scale Version 3.0 (SIS 3.0)
The SIS 3.0 is a stroke-specific instrument of health-related quality of life. It contains 59 items measuring 8 domains (i.e., strength, hand function, Activities of Daily Living/Instrumental Activities of Daily Living, mobility, communication, emotion. memory and thinking and participation) with a single item assessing perceived overall recovery from stroke. Items are rated on a 5-point Likert scale with lower scores indicating greater difficulty in task completion during the past week. Aggregate scores, ranges from 0 to 100, are generated for each domain.
Time frame: An expected average of 4 weeks
Visual analogue scale (VAS) for assessing post-exertional fatigue and pain
The visual analogue fatigue scale (VAFS) and visual analogue pain scale (VAPS) will be used to assess the level of post-exertional fatigue and post-exertional pain. The VAS consists of score ranges from 0 to 100 measured in millimeters on a 10-cm vertical line. The scores will be obtained by measuring the lines from "no fatigue" to "very severe fatigue" and from "no pain" to "very severe pain".
Time frame: An expected average of 4 weeks
Actigraphy
The activity monitors, Actigraphy (Ambulatory Monitoring Inc., New York), quantitatively recording the amount of activity in free-living conditions, will be used to reflect increase in the amount of affected arm use over time. The participants will be asked to wear an Actigraphy on each wrist for 3 consecutive days to measure what amount they actually do in their daily life. The Actigraphy can be attached to the subject's limb and measures the motion of that limb through an accelerometer.
Time frame: An expected average of 4 weeks
Motor Status Score (MSS)
The MSS examines shoulder, elbow (maximum score = 40), wrist, hand, and finger movements (maximum score = 42). The MSS isolates and grades movements of the shoulder, elbow, forearm, and wrist using a 6-point scale (0, -1, 1, +1, -2, and 2), ranging from no volitional movement to perform movements faultlessly. Scoring for the hand is based on a 3-point scale (0, 1, and 2).
Time frame: An expected average of 4 weeks
Wolf Motor Function Test (WMFT)
The WMFT requires the participant to perform 15 function-based and 2 strength-based tasks. The tasks are averaged to produce a score in seconds that ranges from 0 to 120 seconds. For functional ability scoring, we used a 6-point ordinal scale where 0 indicates "does not attempt with the involved arm" and 5 indicates "arm does participate; movement appears to be normal."
Time frame: An expected average of 4 weeks
Medical Research Council scale (MRC)
The MRC scale examines muscle power of the affected arm. The MRC scale is reliable measurement in stroke patients with score ranged from 0 to 5. Grade of 0 indicates no contraction, 1: flicker or trace contraction, 2: active movement, with gravity eliminated, 3: active movement against gravity, 4: active movement against gravity and resistance, and 5: normal power.
Time frame: An expected average of 4 weeks
Modified Ashworth Scale (MAS)
The MAS is one of the most frequently used of the clinical scales for assessing muscle spasticity by means of a quick stretch response. Muscle tone of upper limb will be evaluated by the MAS in this project. The scoring of the MAS ranges from 0 (no increase in muscle tone) to 4 (affected part rigid).
Time frame: An expected average of 4 weeks
Revised Nottingham Sensory Assessment (RNSA)
The RNSA includes tactile sensation, kinesthetic sensation, and stereognosis. For tactile sensation, the patient will be asked to indicate whenever he or she feels the test sensation. For kinesthetic sensations, all 3 aspects of movement will be tested: appreciation of movement, its direction and accurate joint position sense. For stereognosis, the object will be placed in the patient's hand for a maximum of 30 seconds. Identification is by naming, description or by pair-matching with an identical set.
Time frame: An expected average of 4 weeks
Myoton
The functional state of skeletal muscle was assessed by using myotonometric measurements with the Myoton (Muomeetria Ltd, Estonia) device, created at the University of Tartu in Estonia. The MYOTON represents a noninvasive way to characterize the viscoelastic properties of skeletal muscle in vivo. Three measurement parameters in the MYOTON: F - Frequency, Hz, characterizes muscle tone; D - Decrement, characterizes muscle elasticity; S - Stiffness, N/m, characterizes muscle stiffness.
Time frame: An expected average of 4 weeks
