简要总结
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.
详细描述
This project has following goals:
- To test the hypothesis of pain as a process of biological value leading to improvement in tactile acuity
- To investigate intra-rater reliability of tests measuring perceptual distortions in pain
- To investigate validity of novel tests measuring perceptual distortions in pain
- To explore the influence of acute neck pain on left/right recognition task
- To explore the effect of acute neck pain on body perception

盲法说明
Participants will not be informed about the hypotheses tested and will not be informed about the sham-injection condition. The fact that they received only one injection during the study period will be uncovered at the end of the project.
Examiner will be blinded towards conditions sequence. Between pre-test and post-test examiner will not be present in the research room to provide blinding towards the manipulation provided (control, saline injection, sham injection).

结局指标
主要结局
Tactile acuity measured by two-point discrimination test (TPD).
时间窗: TPD change from baseline at 30 seconds post-manipulation period (e.g. saline injection).
Mechanical callipers will be delicately applied to the spot just below the location where real or sham injection will be administered. Tactile stimuli will be applied until the very first blanching of the skin. Testing will be commenced with 0 mm between the two calliper's tips, and then the distance between them will be gradually increased until participants will able to verbally report that two points had been touched instead of one. Subsequently, the descending sequence will be applied until the perception of the two points disappeared.
次要结局
- Sensory dissociation measured by two-point estimation task (TPE).(Measured at baseline and ~30 seconds after manipulation (e.g. saline injection).)
- Laterality judgements measured by left/right recognition application.(Measured at baseline and ~30 seconds after manipulation (e.g. saline injection).)
