Study Overview
Brief 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.

Masking Description
Participants will be assigned to one of the groups through a number contained in an opaque envelope. Only the physiotherapist in charge of applying the intervention sessions will know the assignment group of each participant.

Outcomes
Primary Outcomes
Stability
Time Frame: 60 minutes
To analyze static balance, a Carbon 5 Flex® pressure platform will be used. It will be measured before and after the application of each experimental situation
Fugl Meyer Assessment Scale
Time Frame: 60 minutes
This scale assess upper limb, lower limb, balance, sensibility, range of motion and pain in patients with stroke.
Fullerton Advance Balance Test
Time Frame: 60 minutes
This scale assess balance and postural control. It has a total punctuation of 40 points. People who are under 25 points have risk of fall.
Posture
Time Frame: 60 minutes
To analyze static posture, a pressure platform will be used. It will be measured before and after the application of each experimental situation
Fluff Test
Time Frame: 60 minutes
It is a tool specifically designed to assess body representation in patients with hemineglect, through a body examination with closed eyes, and the removal of stickers located on both sides of the body. The percentage of stickers removed from each part of the body is assessed. It will be measured before and after the application of each experimental situation
Diller's cancelation test
Time Frame: 60 minutes
This scale assess USN by crossing letters H included with distractors. The number of letters crossed are calculated.
Bisection of the line
Time Frame: 60 minutes
It is one of the most used tools in the assessment of hemineglect. It consists of marking the middle of a line and evaluating how much deviation to the right occurs. The distance in centimeters to the center of the line is calculated. It will be measured before and after the application of each experimental situation
