Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Doctors sometimes treat chronic pain with devices that send mild electrical currents into the spinal cord. This type of treatment is referred to as neurostimulation. A common form of neurostimulation therapy is spinal cord stimulation (SCS). In this study, researchers want to learn more about how SCS affects pain processing and relieves pain. The researchers will examine multiple forms of SCS in chronic pain patients who are receiving SCS from their own doctors as part of their standard of care. During the study, participants will be asked to complete a variety of evaluations at certain time points.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

Subjects will receive each treatment for seven days following one of six randomly-allocated sequences
Primary Study Purpose

TREATMENT

Blinding Strategy

TRIPLE

Participants Investigators Outcome Assessors
There will be two research teams. One team will be unblinded (e.g., clinical care provider/company representative, study coordinator) and will perform stimulator programming/adjustment, and the other team will be blinded (e.g., research personnel) and will perform clinical testing and collect study outcome measures.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Burst / kHz / Sham / Tonic

Participants will be randomized to one of six treatment arms. Participants will receive burst, kHz, tonic, and sham spinal cord stimulation (SCS). Each treatment will be applied for a duration of seven days. Participants will be blinded during programming.

Group Type EXPERIMENTAL

Spinal cord stimulation

Intervention Type DEVICE

Researchers will program the spinal cord stimulation (SCS) system to deliver, according to the randomization status of the participant, burst, kHz, tonic, and sham stimulation.

Burst / Sham / kHz / Tonic

Participants will be randomized to one of six treatment arms. Participants will receive burst, kHz, tonic, and sham spinal cord stimulation (SCS). Each treatment will be applied for a duration of seven days. Participants will be blinded during programming.
