Arm && Interventions

Group	Intervention	Description
whole-body vibration group	whole-body vibration training	Subjects in the whole-body vibration group received half an hour of daily conventional upper limb training, followed by whole-body vibration training for an additional half hour per day,5 days per week during a 3-week period
control group	conventional upper limb training	Over a 3-week period, the subjects in the control group received 1 hour daily of conventional upper limb training 5 times a week,including compensatory techniques for activities of daily living, UE strength, therapist-guided techniques for facilitating normal UE movement patterns,and range of motion and traditional positioning

Primary Outcome Measures

Name	Time	Method
upper-extremity Fugl-Meyer Scale	After the 3-week intervention period	the assessment is scored by summing item ratings and reporting the aggregate score out of 66 points,with higher scores representing a greater UE motor ability summing item ratings and reporting the aggregate score out of 66 points, with higher scores representing a greater UE motor ability
Wolf Motor Function Test	After the 3-week intervention period	participants were timed as they completed 15 activities that progressively involved more difficult arm movements and interactions with objects such as lifting a soda can, stacking checkers, and folding a towel. We reported the average time to perform the 15 items and the evaluator rated the normalcy of these items with a 6-point ordinal scale (range,0-5) using the functional ability scale.
Surface electromyography	After the 3-week intervention period	Surface electromyography was used to measure the integrated EMG（IEMG）of the biceps and triceps during maximum isometric voluntary contraction（MIVC）of the affected elbow flexion and extension and then the co-contraction rate（CR）was calculated
