Background: Peripheral nerve stimulation (PNS) has been used for over 50 years to treat chronic pain by delivering electrical pulses through small electrodes placed near targeted peripheral nerves those outside the brain and spinal cord. Early PNS systems often required invasive neurosurgical procedures. However, since 2015, the Food and Drug Administration (FDA) approved percutaneously implanted PNS leads and neurostimulators  offering a much less invasive, non-opioid option for managing recalcitrant chronic pain.

Background: The frequency of performance of interventional techniques in chronic pain patients receiving anticoagulant and antiplatelet therapy continues to increase. Understanding the importance of continuing chronic anticoagulant therapy, the need for interventional techniques, and determining the duration and discontinuation or temporary suspension of anticoagulation is crucial to avoiding devastating complications, primarily when neuraxial procedures are performed. Anticoagulants and antiplatelets target the clotting system, increasing the bleeding risk.

Background: The sacroiliac joint is well known as a cause of low back and lower extremity pain. Prevalence estimates are 10% to 25% in patients with persistent axial low back pain without disc herniation, discogenic pain, or radiculitis based on multiple diagnostic studies and systematic reviews. However, at present there are no definitive management options for treating sacroiliac joint pain.

Background: The therapeutic spinal facet joint interventions generally used for the treatment of axial spinal pain of facet joint origin are intraarticular facet joint injections, facet joint nerve blocks, and radiofrequency neurotomy. Despite interventional procedures being common as treatment strategies for facet joint pathology, there is a paucity of literature investigating these therapeutic approaches. Systematic reviews assessing the effectiveness of various therapeutic facet joint interventions have shown there to be variable evidence based on the region and the modality of treatment utilized.

Article Synopsis
  • * Of the 31 trials reviewed, strong evidence (Level I) indicated that local anesthetics combined with steroids effectively manage chronic spinal pain, with similar results noted for local anesthetic alone, except in cases of disc herniation.
  • * The review concluded that while local anesthetic with steroids and local anesthetic alone show equal effectiveness for most spinal conditions, local anesthetic with steroids is superior for patients with disc herniation.

Background: Lumbar discogenic pain without pain mediated by a disc herniation, facet joints, or the sacroiliac joints, is common and often results in chronic, persistent pain and disability. After conservative treatment failure, injection therapy, such as an epidural injection, is frequently the next step considered in managing discogenic pain. The objective of this systematic review is to determine the efficacy of lumbar epidural injections in managing discogenic pain without radiculopathy, and compare this approach to lumbar fusion or disc arthroplasty surgery.

Article Synopsis
  • Chronic neck pain is common and affects individuals' health and the economy, with various treatment options like surgery, conservative measures, and injections being explored for relief.
  • The study aimed to evaluate the long-term effectiveness of cervical interlaminar and transforaminal epidural injections for conditions such as disc herniation and spinal stenosis.
  • Findings revealed that while there is decent evidence supporting the interlaminar approach, especially for specific pain types, limited research exists on the transforaminal method, highlighting a need for more randomized trials.

Objective: This pilot study was designed to evaluate the impact of a home-based aerobic conditioning program on symptoms of fibromyalgia and determine if changes in symptoms were related to quantitative changes in aerobic conditioning (VO(2) max).

Methods: Twenty-six sedentary individuals diagnosed with fibromyalgia syndrome participated in an individualized 12-week home-based aerobic exercise program with the goal of daily aerobic exercise of 30 minutes at 80% of estimated maximum heart rate. The aerobic conditioning took place in the participants' homes, outdoors, or at local fitness clubs at the discretion of the individual under the supervision of a physical therapist.

Low back pain is the most common pain symptom experienced by American adults and is the second most common reason for primary care physician visits. There are many structures in the lumbar spine that can serve as pain generators and often the etiology of low back pain is multifactorial. However, the facet joint has been increasingly recognized as an important cause of low back pain.
