Title: Effects of Computer-aided Interlimb Force Coupling Training on Paretic Hand and Arm Motor Control Following Chronic Stroke
Brief Summary: The investigators hypothesized that bilateral handgrip force training would result in significant improvements in paretic hand, arm movements and daily functional performances. In order to investigate whether the improvement of paretic hand could facilitate the motor recovery of paretic arm and functional performances, the investigators also hypothesized that motor recovery and functional performances improvements of paretic arm and hand have strongly correlation.


Options:
A: Inclusion Criteria:

1. at least 6 months since stroke
2. three or fewer incidents of unilateral stroke confirmed by taking the participant's medical history ability to follow researcher's instructions
3. ability to flex and extend the paretic arm and hand
4. Modified Ashworth Score (MAS) ≦3 for wrist and finger joints
5. Mini-Mental State Examination (MMSE) score should 24 or higher
6. no other orthopedic neurological disorders
7. Brunnstrom stage 3 or 4
8. no joint in other experimental rehabilitation or drug studies 21

Exclusion Criteria:

1. unstable cardiovascular conditions
2. uncontrolled hypertension (190/110 mm Hg)
3. severe orthopedic or pain conditions
4. dementia (Mini-Mental State Examination score \< 22)
5. aphasia with inability to follow researcher's commands
6. severe joint contracture of bilateral upper extremities that would impact the movement performances of upper extremities
B: Inclusion Criteria:

* Living in the city of Trondheim or the municipalities of Asker or Bærum
* Included 2.5 - 4 months after stroke
* Modified Rankin Scale 0 - 4

* Other diseases that make it difficult to complete the intervention
C: Inclusion Criteria:

* Informed consent
* Clinical diagnosis of first or recurrent stroke, hemorrhage or infarct.
* Recruited within 24 hours of onset of stroke symptoms
* Admission in a stroke care unit
* Consciousness: At a minimum patient must at least react to verbal commands.

Exclusion Criteria:

* pre stroke mRS of 3,4 or 5
* Deterioration in patients condition resulting in direct admission to ICU, decision to palliate or surgery.
* Concurrent diagnosis of rapidly deteriorating disease
* Unstable coronary or other medical condition that is judged by the investigator to impose a hazard to the patient by involvement
* Patients unable to be mobilized within 24 hours of onset. (eg bed rest policy post tPA, lower limb fracture)
* Other interventional trials
* Systolic BP less than 110 or greater than 220mmHg
* Oxygen saturation of less than 92 % with supplementation
* Resting heart rate of less than 40 or greater than 110 beats per minute
* Temperature of greater than 38.5 degrees C
D: Inclusion Criteria:

Subjects in this study will:

* be aged over 50 years.
* be between one week and three months after stroke when recruited to the study;
* have been independently mobile indoors, with or without aids, before the stroke;
* have some voluntary movement in the paretic lower limb i.e. score above 28/100 on the lower limb section of the Motricity Index43;
* demonstrate adequate orientation and communication (be able to complete a one-stage command using the non-paretic upper limb e.g. point at the ceiling).

In addition those who agree to participate in TMS measurement will have no contraindications to TMS.
