St. Jude Medical to study neuromodulation combo treatment for back and leg pain

St. Jude Medical ($STJ) has begun enrolling patients in a clinical trial to test whether combining peripheral nerve field stimulation and spinal cord stimulation to manage chronic low back and leg pain is more effective than spinal cord stimulation alone. The Minnesota company's SENSE trial is a randomized, prospective, multicenter clinical study designed to enroll up to 450 patients at up to 35 U.S. sites. Separately, St. Jude launched a clinical trial to test its Prodigy neurostimulator as a treatment for chronic pain. The device uses burst stimulation rather than tonic stimulation, an advance thought to reduce or eliminate the tingling sensation caused by the latter option. Item
