Laterality Discrimination in Patients With Non-specific Chronic Neck Pain

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.

About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • The inclusion criteria were as follows: a) men and women aged between 18- and 65-years b) medical diagnosis of Non-Specific Chronic Neck Pain with more than 6 months of evolution of neck pain.

Exclusion criteria

  • Exclusion criteria included the following: a) patients with rheumatic diseases, cervical hernia, cervical whiplash syndrome, neck surgeries or history of arthrodesis, b) systemic diseases, c) vision, hearing or vestibular problems, d) Severe trauma or traffic accident which has had an impact on the cervical area.

Treatment and study plan

Neck Laterality

Behavioral

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

Foot Laterality

Behavioral

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

Primary outcomes

  1. Response time

    Time frame: Immediately post-intervention

    Changes in the time response. Time response is defined as the time between the image appearance and the subject response.

  2. Accuracy

    Time frame: 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.

  3. Joint Position Error

    Time frame: Immediately post-intervention

    Changes in the joint position error at the end of the intervention. It is measured on centimeters.

  4. Cervical Active Range of Motion

    Time frame: immediately post-intervention

    Changes the cervical active range of motion at the end of the intervention. It is measured on centimeters.
