QST and Neuropathic Pain
A Prospective Open Labelled Study to Evaluate if Central Sensitization as Measured With QST Alters Following Chronic Pain Interventions
To establish the sensory profile of patients using quantitative sensory testing (QST) and questionnaires as well as the level of sensitisation using temporal summation and diffuse noxious inhibitory control paradigms in all patients undergoing a chronic pain intervention at Barts Health NHS Trust.
Primary objective- To identify the phenotype of responders and non-responders to a chronic pain intervention using QST sensory profile as well as the sensitisation paradigms.
Secondary objective- To establish the correlation between sensory profile, and sensitisation parameters as well as other measures of chronic pain as per Initiative on Methods, Measurement and Pain Assessment in clinical trials (IMMPACT) recommendation.
Common interventions performed at Barts Health NHS Trust includes Neuromodulation, targeted epidural steroid and/or radiofrequency treatment, 8% Capsaicin patch and pharmacological interventions such as anti-neuropathic agent and opioids.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
• To identify the phenotype of responders and non-responders to a chronic pain intervention using QST sensory profile as well as the sensitisation paradigms.
Time Frame: QST changes at 4 weeks is taken as primary objective.
|
This is assessed by comparing and reporting any change in QST results before and after the intervention.

QST changes at 4 weeks is taken as primary objective.
