This study shows that a new oculomotor prismatic training can effectively reduce spatial neglect symptoms in patients with right brain damage. The training helps patients regain awareness of their left visual field.
Area of Science:
- Neuroscience
- Rehabilitation Medicine
- Ophthalmology
Background:
- Spatial neglect is a common neurological deficit after right brain damage, causing unawareness of the left side of space.
- Visuomotor prismatic training is an established rehabilitation method for spatial neglect.
Purpose of the Study:
- To investigate the efficacy of a novel oculomotor prismatic training (OPT) for reducing spatial neglect.
- To explore the underlying mechanisms of OPT-induced amelioration of spatial neglect.
Main Methods:
- Patients with spatial neglect underwent a training protocol involving sequences of gaze shifts with prisms.
- Neglect severity was assessed using straight-ahead and paper-and-pencil tasks before and after training.
Main Results:
- Oculomotor prismatic training significantly reduced spatial neglect severity.
- Patients showed improvements in both straight-ahead and paper-and-pencil tasks post-training.
Conclusions:
- A novel oculomotor prismatic training procedure effectively alleviates spatial neglect symptoms.
- The training's effectiveness may stem from the brain adapting to conflicting sensory inputs (visual/oculomotor vs. proprioceptive).
