Chronic Pain
Conditions
Brief summary
The main objective of this research is to evaluate the influence of different distraction stimuli on neural mechano-sensitivity tests.
Interventions
BEHAVIORALmedian nerve mobilization
The patient is placed in a supine position and his cervical spine with 25º of lateral flexion on the opposite side of the member in which we perform the test. First a passive scapular depression is performed, 90º of shoulder abduction combining external shoulder rotation. Next, a supination of the forearm is performed with wrist extension and finger extension. Finally, the elbow is extended to the limit of resistance or when the investigator observes the elevation of the shoulder girdle.
BEHAVIORALNeural stress provocation with cognitive auditory distraction
Neural provocation of the median nerve is performed but an auditory distraction is added with a metronome with a constant time of 50 beats per minute.
BEHAVIORALProviding neural stress with a motor distraction
The neural provocation of the median nerve is performed and we add a motor distraction that consists of the patient intermittently squeezing a ball with the opposite hand.
BEHAVIORALNeural stress provocation with auditory and motor cognitive distraction.
The neural provocation of the median nerve is performed, we add auditory distraction with the metronome with a constant time of 50 BPM and a motor distraction consisting of squeezing a ball to the rhythm that sounds the metronome.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Mechanosensitivity based on range of motion | Change in pressure pain threshold immediately at the end of the intervention | The inclinometer, an instrument characterized by the constant use of gravity as a reference point to evaluate mobility, is used to evaluate the range of nerve movement. |
| Pain intensity | Change in pain intensity immediately at the end of the intervention | It is the subjective feeling of self-reported pain ranging from 0-100 points. |
