Effect of Spinal Cord Stimulation on Pain Thresholds and Sensory Perception in Chronic Pain Patients.

Completed

Conditions studied: Chronic Pain

In brief

The purpose of this study is to better understand how the Spinal Cord Stimulator works in relieving chronic pain. The investigators are asking subject to take part in this study because who are chronic pain patients who already have a Spinal Cord Stimulator (SCS) in place. The investigators hypothesize that chronic pain patients will have higher heat pain threshold and heat pain tolerance over the painful areas with the SCS on. QST (Quantitative Sensory Testing, a heat/cold simulation test) might be an objective helpful tool for prudent patient selection for an expensive and invasive procedure for future SCS placement.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Subject is 18 years or older.
• Subject has an SCS device implanted for at least one month for pain control. This requirement is set to ensure that the subject becomes familiarized with the therapy and has recovered from the surgical implantation of the SCS device.

You may not qualify if…

• Subject has neurological disease or a condition causing sensory deficit to the painful area.
• Subject had recent therapy that may influence QST results, e.g., neuroablative procedure within two-months.
• Subjects who are unable to travel to the study center.
