简要总结
The purpose of this study is to investigate the efficacy of optokinetic stimulation in stroke patients by examining its effects on spatial neglect, static balance, dynamic balance, and weight-bearing symmetry.
详细描述
In stroke patients the presence of spatial neglect predicts poor outcome in functional recovery, entailing a longer time of hospitalization, greater functional dependency, increased risk of falls and a long-term disability in Activities of Daily Living (ADL). This results in an overall increase of costs for the health system.
Spatial neglect patients' performance in self-care and household is usually compromised. Those patients had more problems in performing self-care and household tasks than non-spatially neglected patients. For example, spatial neglect patients forgot or could not find objects at one side when dressing or in the kitchen and had difficulty eating or using devices. VSN severity had a negative impact on the performance of ADL. Spatial neglect had a negative impact on walking and wheelchair navigation. Spatial neglect had a negative impact on exercise such as walking and jogging .
Patients with spatial neglect had an increased weight-bearing asymmetry favouring the non-paretic leg and increased mediolateral CoP excursions while standing. However, upright standing is an inherently more demanding posture owing to the height of the center of mass relative to the base of support.
Because of all those effects of spatial neglect on outcomes, it is a necessity to engage more neurological rehabilitative procedures focusing on neglect and its complications. One of the treatments used for neglect is optokinetic stimulation (OKS).
The vestibular apparatus is the primary organ of balance which is used mainly during motion when compared to somatosensation. Optokinetic stimulation is known to stimulate areas of the brain such as the brain stem and cerebellum that immediately process balance signals from the vestibular apparatus before they are transmitted to the cerebral cortex via the thalamus. Optokinetic chart stimulation has been reported to restore voluntary movement and mobility in an acute hemorrhagic stroke as well as restore postural control and independent mobility in an acute, ataxic, posterior temporal parietal ischemic stroke.

结局指标
主要结局
Albert test
时间窗: 10 weeks
It is the test used for screening of unilateral spatial neglect .the examiner asked to cross all the lines. The more un crossed lines the worst degree of spatial neglect.
Catherine bergego scale (CGS)
时间窗: 10 weeks
It is a 4 point scale used to indicate the severity of neglect .the total score out of 30 . the higher scores indicate the more severe the spatial neglect
次要结局
- Limit of stability (LOS)(10 weeks)
- The Modified clinical test of sensory interaction on balance (m CTSIB)(10 weeks)
- Center of pressure(10 weeks)
