Trial Outcomes & Findings for Effect of Acupuncture and Pain Medication on Radicular Pain Using QST (NCT NCT01678586)

NCT ID: NCT01678586

Last Updated: 2024-04-23

Results Overview

Changes in response to heat stimulation stated as pain, sensitivity and tolerance. Responses are measured with a quantitative sensory testing (QST) device. Measurements are taken before, during, and after acupuncture treatment and throughout the gabapentin medication regimen. Measurements are taken at Visit 1 (before any intervention), Visit 4 (after session 3 for acupuncture groups or within treatment week 2 for medication groups), and Visit 7 (after session 6 for acupuncture groups or within treatment week 3 for medication groups), up to a maximum of 3 weeks for each participant.

Participant milestones
Measure
True Acupuncture
Pain subjects with radicular pain receiving 6, 30 minute acupuncture treatments. Acupuncture: In true acupuncture the needles penetrate the skin.
Sham Acupuncture
Pain subjects with radicular pain receiving 6, 30 minute sham acupuncture treatments. Sham Acupuncture: In sham acupuncture the needles do not penetrate the skin.
Gabapentin
Pain subjects with radicular pain receiving gabapentin. Medication treatment groups will titrate up to the standard clinical treatment dosage for one week and maintain that dosage for 1.5 weeks. Gabapentin: Gabapentin is a commonly prescribed drug used to treat neuropathic pain.
Sham Gabapentin
Pain subjects with radicular pain receiving sham gabapentin. Medication treatment groups will titrate up to the standard clinical treatment dosage for one week and maintain that dosage for 1.5 weeks. Sham Gabapentin: Benadryl or diphenhydramine is used as a placebo as it could mimic some common side effects of gabapentin (i.e. sedation, drowsiness, lightheadedness)
