About

Research has shown that chronic pain is related to variety of perceptual distortions. Little is known on how acute pain experience influences perception, especially precision of touch. This project is aiming to test the hypothesis of pain as a process of biological value leading to improvement in tactile acuity.

Full description

This project has following goals:

1. To test the hypothesis of pain as a process of biological value leading to improvement in tactile acuity
2. To investigate intra-rater reliability of tests measuring perceptual distortions in pain
3. To investigate validity of novel tests measuring perceptual distortions in pain
4. To explore the influence of acute neck pain on left/right recognition task
5. To explore the effect of acute neck pain on body perception

Enrollment: 30 patients

Sex: All

Ages: 18 to 35 years old

Volunteers: Accepts Healthy Volunteers

Trial design

Primary purpose: Basic Science

Allocation: Randomized

Interventional model: Sequential Assignment

Masking: Double Blind

---

30 participants in 3 patient groups

Saline injection

Experimental group

Description:

In the saline condition, acute neck pain will be induced via 0.5 ml hypertonic (5% NaCl) saline solution.

Treatment:

Other: Saline injection

Sham injection

Sham Comparator group

Description:

In the sham injection condition, a real needle will be shown to the participants to imitate and produce the anticipation of a pain experience.

Treatment:

Other: Sham injection

Control

No Intervention group

Description:

Participants in the control condition will not receive any kind of pain or pinprick sensation.
