Study Overview
Brief Summary
This study aims to assess the immediate effects of action observation therapy on the cervical muscles' strength, pain intensity, tactile acuity and pain pressure threshold in individuals with chronic nonspecific neck pain.
Detailed Description
This study is a randomized controlled trial with two arms: action observation group vs control group. The action observation group will be asked to watch videos of neck exercises with full attention and concentration and not perform any motion or execute any movement during the observation time. The control group will be asked to watch videos of a landscape.
Participants will be assessed at baseline and at post-intervention for muscle strength, pain intensity, pressure pain threshold and tactile acuity.

Outcomes
Primary Outcomes
Pressure pain thresholds
Time Frame: Post-intervention (within the same session of the baseline assessment but approximately 30 minutes after that).
Pressure pain thresholds are the minimum amount of pressure applied with an algometer that is perceived as being painful; is measured in Kgf
Secondary Outcomes
- Pain intensity(Post-intervention (within the same session of the baseline assessment but approximately 30 minutes after that).)
- Neck flexors strength(Post-intervention (within the same session of the baseline assessment but approximately 30 minutes after that).)
- Neck extensors strength(Post-intervention (within the same session of the baseline assessment but approximately 30 minutes after that).)
- Tactile acuity(Post-intervention (within the same session of the baseline assessment but approximately 30 minutes after that).)
- Neck lateral flexors strength(Post-intervention (within the same session of the baseline assessment but approximately 30 minutes after that).)
