Summary

Hemineglect is a sequel to stroke, which appears more frequently when the injury occurs in the right cerebral hemisphere. Hemineglect refers to those patients who do not pay attention to their left side, presenting movement disorders that do not allow them to participate spontaneously in their activities of daily life. There are different methodologies for the treatment of hemineglect. Among them, we find optokinetic stimulation (OKS), which consists of creating an illusory movement to the left to center the patient's frame of reference and thus, make them pay more attention to their left side. In recent years, the effect that this therapy has on motor movement disorders has begun to be explored, although the parameters for its correct application still seem to be unclear. For this reason, our aim is to describe the effect that the OKS has on balance, posture, spatial representation and conscience, and movement disorders in hemineglect. Patients with hemineglect will undergo OKS to see its influence on the recovery of this sequel of stroke.

Conditions

• Perceptual Disorders
• Unilateral Spatial Neglect

Interventions

Type	Name	Description
OTHER	Optokinetic stimulation	Participants are placed in a standing position, with support products, if necessary, and virtual reality glasses will be placed where the visual stimuli will be projected. The study will be carried out for 10 weeks with a frequency of two weekly sessions. During them, the participants will receive stimulation with OKS. Stimulation will be performed at 1 cm/second, the vertical black bars will move to the left. The bars change color and the participants will be asked to detect the changes that will occur in the stimulus.
OTHER	Placebo	Participants are placed in a standing position, with support products, if necessary, and virtual reality glasses will be placed where the visual stimuli will be projected. In this group, stimulation consists of a video with static vertical bars that change their colour at a randon intervals, in the same way that in the intervention group. The difference between groups is that in control group, bars are not in movement, preventing from generating optokinetic stimulation.
