Spasticity of finger extensor
Modified ashworth scale of finger flexor
Time frame: baseline, 2 weeks after baseline, 6 weeks after baseline, 10 weeks after baseline
active range of motion of wrist joint
active range of motion of wrist joint
Time frame: baseline, 2 weeks after baseline, 6 weeks after baseline, 10 weeks after baseline
Brunnstrom stage of stroke recovery of distal upper extremity
Brunnstrom stage of stroke recovery of distal upper extremity. By observing the pattern of participants posture, the stage was scored. The stage ranges from 1 to 6. Higher is better.
Time frame: baseline, 2 weeks after baseline, 6 weeks after baseline, 10 weeks after baseline

Quick Disabilities of Arm, Shoulder & Hand
Quick Disabilities of Arm, Shoulder \& Hand is questionnaire about patients' symptoms as well as ability to perform certain activities in the last week. Total score is obtained by summing the each question, and ranges from 0 (no disability) to 100 (most severe disability).
Time frame: baseline, 2 weeks after baseline, 6 weeks after baseline, 10 weeks after baseline
Grading of active thumb opposition
Grading of active thumb opposition. It is measured by observing the pattern of thumb opposition.
Time frame: baseline, 2 weeks after baseline, 6 weeks after baseline, 10 weeks after baseline
Grip strength
measured by Jamar dynamometer
Time frame: baseline, 2 weeks after baseline, 6 weeks after baseline, 10 weeks after baseline
Active finger extension
Active finger extension. It is graded by observation of voluntary finger extension.
Time frame: baseline, 2 weeks after baseline, 6 weeks after baseline, 10 weeks after baseline
