The purpose of this study is to investigate the effects of vibration stimuli to contra lateral neck muscles on Contraversive Pusher Syndrome, function and neglect in stroke patients.
12 post-stroke subjects will be recruited from neurological rehabilitation department at Loewenstein rehabilitation hospital, Raanana, Israel. The patients will be randomly assigned to one of two groups: 1) Experimental group. 2) Control group. The 2 weeks intervention (10 sessions) in each group will include vibration stimuli (frequency of 1 Hz and amplitude of 20 mm) for 20 minutes and structured standard physiotherapy for 45 minutes. The vibration stimuli in the experimental group will be done to the contralesional neck muscles, whereas the vibration stimuli in the control group will be done in the contralesional hand. Different assessments will be done before the intervention, after the first day of intervention, after two weeks of intervention and one months post-intervention. The tests will include: Clinical Scale for Contraversive Pushing, Lateropulsion Scale, Subjective Straight Ahead, Postural Assesment Scale for Stroke Patients, Anterior and Lateral Functional Reach Test, Posturography, Behavioral Inattention Test, Mesulam Cancellation Test, Line Bisection Test, Dynamic Starry Night and sensation.
Differences between groups will be calculated using t-tests or Mann-Whitney, depending on distribution of normality with corrections for multiple comparisons. Smallest Real Difference (SRD) will be calculated for detecting the minimal detectable change.

| Change in Clinical Scale for Contraversive Pushing | Score range: 0-6. Score of zero indicates no pushing. Assesses pushing during spontaneous body posture, abduction and extension of the nonparetic extremities and resistance to passive correction of tilted posture. | Before the intervention, after the first day of intervention, after 2 weeks (end of intervention), and one month after the end of the intervention (follow up) |
| Measure | Description | Time Frame |

| Change in Lateropulsion Scale | Score range: 0-17. Score of zero indicated no pushing. Assesses pushing during supine, sitting, standing, transfers and walking. | Before the intervention, after the first day of intervention, after 2 weeks (end of intervention), and one month after the end of the intervention (follow up) |
