Brief summary
To investigate the effect of whole body vibration on upper limb motor function in hemiplegic patients with subacute stroke
Interventions
The subjects were exposed to alternating vertical sinusoidal vibration using a Galileo tilting table system.The frequency of WBV ranged from 5 to 20 Hz, and the amplitude ranged from 1 to 6 mm.The subjects were kneeled on the ground, both shoulders flexed at 90 degrees, elbows slightly flexed, their trunk bent in this position and contacted on the platform board with their palms equidistant from the midpoint of the board
OTHERconventional upper limb training
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

Inclusion criteria
* After unilateral stroke 1 to 6 months * An ischemic or hemorrhagic poststroke hemiplegia * No cognitive impairment * Able to reach Brunnstrom stage II or above in the proximal and distal parts of the arms * No excessive pain in the more affected upper extremity * All subjects agreed to participate in the study after receiving explanations regarding the purpose and procedures of the experiment, and they signed an informed consent statement before participation
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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 |
