Clinical Trial 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.

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.

Exclusion Criteria:

• Visual and hearing dysfunction not corrected by eyeglasses/contact lenses or a hearing aid;
• Infectious diseases;

Related Conditions & MeSH terms

• Neck Pain

Intervention

Other:
• Action-observation therapy
Action observation therapy involves the observation and perception of human movement performed by others. The observation of actions performed by others activates in the perceiver the same neural structures responsible for the actual execution of those same actions.
• Placebo
Participants will watch a natural landscape without any human.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Catastrophizing	Measured with the Catastrophizing Scale (range 0-52 and higher values are indicative of higher pain catastrophizing)	Baseline
Other	Disability	Measured using the Neck Disability Index (Range: 0 - 50 and higher values indicate higher disability)	Baseline
Other	Fear of movement	Measured with the TAMPA Scale of Kinesiophobia (range: 13-52 and higher values are indicative of higher levels of fear of movement)	Baseline
Other	Fear-avoidance beliefs	Measured with the Fear-Avoidance Beliefs Questionnaire (range: 0-66 with higher scores indicating higher fear-avoidance beliefs)	Baseline
Primary	Pressure pain thresholds	Pressure pain thresholds are the minimum amount of pressure applied with an algometer that is perceived as being painful; is measured in Kgf	Baseline
