Laterality Discrimination in Patients With Non-specific Chronic Neck Pain

Effects of Laterality Discrimination in Patients With Non-specific Chronic Neck Pain. Randomized Blind Clinical Trial

Chronic neck pain is one of the most common causes of pain, affecting 15% of the adult population, and the fourth leading cause of disability. The recognition of laterality is the ability to recognize a part of the body that belongs to the left or right which is used as a tool to create a normal process of motor planning.

Study Overview

• Status: Completed
• Conditions: Neck Pain
• Intervention / Treatment: Behavioral: Neck Laterality; Behavioral: Foot Laterality

Detailed Description

The most consistent data come from the investigation of the primary motor cortex, in which the cortical representations of the altered body part are affected when there is chronic pain. Occasionally, the primary motor cortex is smaller on the affected side than on the contralateral side.

Recognition of the body schema is altered in the presence of painful disorders. The most common way of assessing the body schema is by motor imagery through the laterality discrimination of the left and right.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Neck Laterality; It was done with 20 images of necks and 4 seconds for each image in the Vanilla program of the tablet application.	Behavioral: Neck Laterality; Patients who belonged to the neck group performed the recognition of laterality with certain parameters. The execution of the recognition began with a test to familiarize themselves with the program at the "Basic" level and then followed the laterality test. It was done with 20 images and 4 seconds for each image in the "Vanilla" program
Experimental: Foot Laterality; It was done with 20 images of feet and 4 seconds for each image in the Vanilla program of the tablet application.	Behavioral: Foot Laterality; Patients who belonged to the foot group performed the recognition of laterality with certain parameters. The execution of the recognition began with a test to familiarize themselves with the program at the "Basic" level and then followed the laterality test. It was done with 20 images and 4 seconds for each image in the "Vanilla" program

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Response time	Changes in the time response. Time response is defined as the time between the image appearance and the subject response.	Immediately post-intervention
Accuracy	Changes in the accuracy at the end of the intervention. Accuracy must be taken as the precision of the response when a subject say wether the image is right or left. It is measured by percentage of success.	Immediately post-intervention
Joint Position Error	Changes in the joint position error at the end of the intervention. It is measured on centimeters.	Immediately post-intervention
Cervical Active Range of Motion	Changes the cervical active range of motion at the end of the intervention. It is measured on centimeters.	immediately post-intervention
