Laterality Discrimination in Patients With Non-specific Chronic Neck Pain

Not Applicable

Completed

• Conditions: Neck Pain
• Interventions: Behavioral: Foot Laterality; Behavioral: Neck Laterality

• Registration Number: NCT03861312
• Lead Sponsor: Centro Universitario La Salle

Brief Summary

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.

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.

Arm && Interventions

Group	Intervention	Description
Foot Laterality	Foot Laterality	It was done with 20 images of feet and 4 seconds for each image in the Vanilla program of the tablet application.
Neck Laterality	Neck Laterality	It was done with 20 images of necks and 4 seconds for each image in the Vanilla program of the tablet application.

Primary Outcome Measures

Name	Time	Method
Accuracy	Immediately post-intervention	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.
Cervical Active Range of Motion	immediately post-intervention	Changes the cervical active range of motion at the end of the intervention. It is measured on centimeters.
Response time	Immediately post-intervention	Changes in the time response. Time response is defined as the time between the image appearance and the subject response.
Joint Position Error	Immediately post-intervention	Changes in the joint position error at the end of the intervention. It is measured on centimeters.
