Spinal manipulation is often used for its effect on pain, but more information is needed concerning its mechanisms of action.
The effect of spinal manipulation on the pressure pain threshold in asymptomatic subjects should be challenged by a validated sham procedure, regionally and remotely over time. Further information is needed concerning its duration and its size.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Spinal manipulation | Experimental | The spinal manipulation is located between the fifth and eighth thoracic vertebrae, on a level and a side pain-free to a light palpation. The maneuver is of high velocity and low amplitude, oriented posterior to anterior, on the transverse process area of the chosen thoracic vertebrae. |
|
| Sham procedure | Sham Comparator | The sham procedure is a manual contact on both inferior angles of the scapulae by the chiropractor. After a short tensioning, a slight movement with low velocity and low amplitude is done, respecting scapula-thoracic sliding plans laterally, without repercussion on the spine. It is considered by us to be a "credible" sham procedure, as it resembles an actual act of thoracic manipulation, and it has been validated, with questionnaires. |

|---|---|---|---|---|
| Spinal manipulation | Other | Spinal manipulation is defined as a quick, passive and forced manoeuvre applied to spinal joints, and sometimes followed by a characteristic cracking sound. It can be compared to a mobilisation, which is a passive manual therapy as well, but is applied slower and repetitively on the joints. Spinal manipulation has been shown to have a significant clinical impact in the treatment of musculoskeletal pain |
| Measure | Description | Time Frame |
|---|---|---|
| Change of the Pressure Pain threshold | Pressure Pain Threshold is defined as the minimal pressure that provokes a pain or a discomfort. It is considered as a valid and objective method, with a good reliability. | The change of the Pressure Pain Threshold is assessed from baseline to immediately after spinal manipulation, and then every fifteen minutes for about an hour. |
