Wireless high-frequency dorsal root ganglion stimulation for chronic low back pain: A pilot study.
Evaluation of the efficacy of a wireless high-frequency stimulator placed over selected DRG of exiting nerve roots for the treatment of chronic low back pain. ⋯ Wireless high-frequency stimulation of the DRG is a viable option to treat chronic low back pain. Preliminary results show a subject preference for stimulation at the T9 vertebral level.

Low back pain (LBP) is associated with both axial discomfort and radiating leg pain. Although intervertebral discs are suspected as the source of pain in some individuals, the relationship between disc degeneration and back pain remains controversial. The goals of this study were to investigate the long-term impact of L4/L5 disc puncture on disc degeneration and the subsequent emergence, persistence, and underlying mechanisms of axial and radiating LBP in mice. ⋯ Radiating pain then reemerged 9 to 12 months after injury in half the animals and correlated with increased dorsal innervation and reduced disc height at these late time points. In summary, a single-level disc injury is sufficient to induce prolonged disc degeneration and delayed axial and radiating pain. This model will be useful to investigate underlying mechanisms and potential therapeutic strategies for discogenic LBP.

Chronic low back pain (CLBP) is challenging to treat. Minimal invasive neurostimulation therapies, such as subcutaneous peripheral nerve field stimulation (SPNS), improve pain relief and quality of life. The goal of the present study was to assess the usefulness, safety, and efficacy of SPNS in patients with CLBP. ⋯ The complication rate was 23% (3/13 patients). In non-responders, VAS and ODI at 24 months dropped significantly as well but the decrease was less pronounced compared to responders and had not led to a decrease in pain medication. SPNS is a novel, safe, and effective treatment for CLBP and may have advantages over interventional treatments including intrathecal therapy and spinal cord stimulation.

Chiropractic care is a popular alternative for back and neck pain, with efficacy comparable to usual care in randomized trials. However, the effectiveness of chiropractic care as delivered through conventional care settings remains largely unexplored. ⋯ We found no statistically significant difference between the two groups in either patient-reported or economic outcomes. As clinical outcomes were similar, and the provision of chiropractic care did not increase costs, making chiropractic services available provided an additional viable option for patients who prefer this type of care, at no additional expense.
