简要总结
One of the causes of disability in patients suffering from a stroke is postural imbalance. Sensory stimulation improves the postural symmetry of the subject transitorily and they are thought to have an effect on the spatial frame of reference through a sensory recalibration. Studies have shown that sensory stimulation by vibration of neck muscles have an immediate effect on static balance and when walking. The objective of this preliminary study is to test the long-lasting effects of repetitive neck muscle vibrations on postural disturbances in standing position and on spatial frame reference in chronic patients.
详细描述
The hypothesis of this study is that the proprioceptive repeated stimulation by vibration of neck muscles in the long term improved postural asymmetry in connection with the egocentric representation of body disorders.
The effect of vibration simultaneously on improving postural asymmetry and on improving markers of the perception of the body in space (LBA, SSA, Subjective Visual Vertical (SVV), Rod and frame) will be assessed.

结局指标
主要结局
Changes from baseline Weight Bearing Asymmetry at Day 15
时间窗: Before and after the intervention program (Day 15)
The primary evaluation criteria is the percentage of the Weight Bearing Asymmetry on the hemiparetic lower limb (WBA) calculated as the mean of 4 trys, each based on a 30 seconds duration with the two eyes open (OP) and then again with the two eyes closed. This evaluation is realized on a force platform.
次要结局

- Change from baseline of patients' motor skills(1 month after the end of the program)
- Haptic and visual Subjective Straight Ahead (SSA) test(7 days and 15 days after the start of the intervention)
- Evaluation of Longitudinal Body Axis (LBA)(7 days and 15 days after the start of the intervention)
- Rod and Frame Test(7 days and 15 days after the start of the intervention)
- Change from baseline of patients' functional capacity(1 month after the end of the program)
- Change from baseline of patients' sensitivity(1 month after the end of the program)
