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.

Arm && Interventions

Group	Intervention	Description
Intervention Group	Optokinetic stimulation	-
Control Group	Placebo	-

Primary Outcome Measures

Name	Time	Method
Fugl Meyer Assessment Scale	60 minutes	This scale assess upper limb, lower limb, balance, sensibility, range of motion and pain in patients with stroke.
Fullerton Advance Balance Test	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	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	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	60 minutes	This scale assess USN by crossing letters H included with distractors. The number of letters crossed are calculated.
Stability	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
Bisection of the line	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

Secondary Outcome Measures

Name	Time	Method
Sex	1 minute	The sex of the participants is recorded at the start of the study
Date of injury	1 minute	The date of the injury is registered in order to calculate the time of evolution with the disease
Date of birth	1 minute	The participant's date of birth is collected in order to calculate his age in years
Admission time	1 minute	Date of involvement in study
National Institutes of Health Stroke Scale	10 minutes	is a tool used by healthcare providers to objectively quantify the impairment caused by a stroke. The NIHSS is composed of 11 items, each of which scores a specific ability between a 0 and 4. For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment. The individual scores from each item are summed in order to calculate a patient's total NIHSS score. The maximum possible score is 42, with the minimum score being a 0.
Type of injury	1 minute	Description of injury to analyse if it has some effect during intervention
