At 6 months post-implant, 64% of patients had achieved the 50% reduction in leg pain criterion (vs. For example, in a recent demonstration, randomized 100 failed back surgery syndrome (FBSS) patients to either SCS or conventional medical management. For these patients, SCS can be an effective alternative. Many chronic LBP patients have conditions not amenable to spine surgery, or they have failed to achieve successful outcome with previous spine surgery. Chronic LBP can also limit flexibility and/or range of motion, which may contribute to an overall decrease in functional capacity, and may ultimately heighten the risk for additional lower extremity injury. Low back pain is the second leading cause for missed days at work, potentially having disability and major socioeconomic consequences. However, the small percentage of people who do not recover quickly present a costly problem to society and a great challenge to health care providers. Fortunately, 80-90% of individuals recover from their back pain, whether they receive treatment or not. Low back pain is reported in 75-80% of the population and can significantly influence patients' quality of life. Condition or diseaseĬhronic Low Back Pain Pain in Leg, Unspecified Also, explored will be the relationship of changes in gait and balance to psychosocial factors that have previously been shown to be correlated with SCS outcomes. Objective spine and lower extremity motion and neuromuscular control will be evaluated using dynamic surface EMG and a video motion capture system during functional evaluation. In addition, 50 control subjects having no pain will undergo 1 session of gait and balance assessment. Fifty subjects with symptomatic leg pain and/or low back pain (LBP) who are deemed appropriate SCS candidates and are scheduled for surgery will undergo gait and balance analyses preoperatively as well as 6 weeks and 3 months post operatively. Successful SCS implants lead to a broad range of positive outcomes: 1) long-term pain can be expected to be reduced by at least by 50% 2) quality of life as assessed by subjective measurements improves substantially 3) patients can significantly reduce opioid medication intake.1 However, the impacts of SCS intervention on neuromuscular and biomechanical outcomes including gait and balance have not been fully explored. Spinal Cord Stimulation (SCS) uses electrical signals to disrupt noxious signals arising from painful areas, thereby reducing pain perception. Why Should I Register and Submit Results?.
