Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Painful Manual Therapy
Manual therapy treatment shall be carried out at a high intensity that causes pain to the patient.
The aim is to provoke a medium intensity pain to the patient of 5/10 in the NRS.
The physiotherapist will ask every 30 seconds the pain provoked by the treatment with the numeric rating scale (NRS) and the patient will give continuous feedback.
Based on this, the physiotherapist will adapt the intensity of the treatment to provoke a medium intensity pain.
|
|
Active Comparator: Painless Manual Therapy
Manual therapy treatment shall be performed at a low intensity that does not cause pain to the patient.
The aim is for the patient to report a pain intensity of 0/10 in NRS throughout treatment.
The physiotherapist will ask every 30 seconds the pain provoked by the treatment with NRS and the patient will give continuous feedback.
Based on this, the physiotherapist will adapt the intensity of the treatment to be performed below the pain threshold.

To evaluate conditioned pain modulation (CPM), a handheld pressure algometer will be used as the test stimulus to evaluate the PPT at the nail bed of the thumb of the symptomatic side before and during application of a conditioning stimulus.
Ischemic muscle pain will be used as the conditioning stimulus using a sphygmomanometer.
The sphygmomanometer will be applied around the upper arm of the asymptomatic side, with its lower rim 3 cm proximal to the cubital fossa.
The cuff was inflated to 260 mmHg and maintained until the subject perceived a 7/10 pain on the NRS.
The CPM will be the result of the PPT during the conditioning stimulus minus the PPT before the conditioning stimulus.

To evaluate conditioned pain modulation (CPM), a handheld pressure algometer (Model FPX, Wagner instruments, Greenwich, CT, USA) will be used as the test stimulus to evaluate the PPT at the nail bed of the thumb of the symptomatic side before and 1 minute after application of a conditioning stimulus.
Ischemic muscle pain will be used as the conditioning stimulus using a sphygmomanometer.
The sphygmomanometer will be applied around the upper arm of the asymptomatic side, with its lower rim 3 cm proximal to the cubital fossa.
The cuff was inflated to 260 mmHg and maintained until the subject perceived a 7/10 pain on the NRS.
The CPM will be the result of the PPT after the conditioning stimulus minus the PPT before the conditioning stimulus.

Change from Baseline in Termporal Summation of Pain (TSP) to immediate post-intervention
Time Frame: At baseline and immediately after the intervention
|
TSP will be elicited with 10 applications of the algometer (Model FPX, Wagner instruments, Greenwich, CT, USA) at the individual PPT intensity perceived at the nail bed of the thumb of the asymptomatic side.
For each pulse, the pressure will be increased at a rate of approximately 2 kg/second to the previously determined PPT intensity.
Pulses will be presented with an interstimulus interval of 1 second because this has previously been shown to be optimal for inducing TSP with pressure pain.
Before application of the first pressure pulse, subjects were instructed to manually rate the pain intensity of the first and 10th pulse with a NRS.
The TSP will be calculated as the difference between the pain intensity of the tenth stimulus minus the first stimulus.
|
At baseline and immediately after the intervention
|
Self-perceived improvement by Global Rating of Change (GROC scale) immediately after the intervention
Time Frame: Immediately after the intervention
|

|
Immediately after the intervention
|
Change from Baseline in Cold Pain Intensity to immediate post-intervention
Time Frame: At baseline and immediately after the intervention
|
Cold pain intensity will be evaluated with the subject resting on a chair with the ice application test. Testing will be conducted on the anterior skin of the right forearm. For the ice application test, the ice pack will be held on the skin for 10 s. After 10 s of ice application, subjects will be instructed to rate the intensity of pain on NRS. The procedure will be repeated three times to obtain a mean value, with a 60 s rest period between measures to avoid summation of pain. |
