Arms & Interventions
control group
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
Intervention: conventional upper limb training (Other)
whole-body vibration group
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
Intervention: whole-body vibration training (Device)
Outcomes
Primary Outcomes
upper-extremity Fugl-Meyer Scale
Time Frame: 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
Time Frame: 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
Time Frame: 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
Secondary Outcomes
No secondary outcomes reported
