This study assessed the real-world effectiveness of 10 kHz spinal cord stimulation (SCS) in improving pain, function, and quality of life in chronic, treatment-resistant leg pain.
Individuals suffering from chronic intractable leg pain experience meaningful, long-term improvements in pain, function, and quality of life with 10 kHz spinal cord stimulation.
This study assessed the real-world effectiveness of 10 kHz spinal cord stimulation (SCS) in improving pain, function, and quality of life in chronic, treatment-resistant leg pain.
In this prospective study, investigators enrolled patients from 12 clinical sites who had leg pain unresponsive to conservative treatments and reported a score of ≥5 cm on a 10-cm visual analog scale (VAS). Those who experienced at least a 50% reduction in leg pain during a temporary SCS trial proceeded to permanent implantation and were monitored over a 12-month period.
The key outcomes encompassed the proportion of patients attaining ≥50% VAS reduction, improvements in health-related quality of life (EuroQol 5-Dimensions 5-Levels [EQ-5D-5L]), functional disability (Oswestry Disability Index [ODI]), opioid use, sleep quality (Pain and Sleep Questionnaire 3-Item [PSQ-3]), global impression of change, and overall patient satisfaction.
Of the 121 subjects who underwent trial stimulation, 118 completed it, and 95 received permanent implants. At 3 months post-implantation, 64.2% (61/95) of the patients reported a ≥50% drop in leg pain, a result that remained consistent at the 12-month follow-up. Significant and sustained improvements were witnessed in EQ-5D-5L, ODI, and PSQ-3 scores over time. Additionally, patients reported a prominent reduction in opioid use. The safety outcomes were in line with previously established data for 10 kHz SCS.
For chronic intractable leg pain, 10 kHz spinal cord stimulation is a safe and effective treatment option, offering substantial relief from disability and pain while boosting well-being.
