Often disabling, BRLP accounts for greater work loss, recurrences, and higher costs than uncomplicated LBP and more often leads to surgery with a lifetime incidence of 10% for those with severe BRLP, compared to 1-2% for those with LBP. In the US, half of those with back-related conditions seek CAM treatments, the most common of which is chiropractic care. While there is preliminary evidence suggesting chiropractic spinal manipulative therapy is beneficial for patients with BRLP, there is insufficient evidence currently available to assess the effectiveness of this care. ![]() ![]() Methods/Design This study is a two-site, prospective, parallel group, observer-blinded randomized clinical trial (RCT). A total of 192 study patients will be recruited from the Twin Cities, MN (n = 122) and Quad Cities area in Iowa and Illinois (n = 70) to the research clinics at WHCCS and PCCR, respectively. It compares two interventions: chiropractic spinal manipulative therapy (SMT) plus home exercise program (HEP) to HEP alone (minimal intervention comparison) for patients with subacute or chronic back-related leg pain. Discussion Back-related leg pain (BRLP) is a costly and often disabling variation of the ubiquitous back pain conditions. As health care costs continue to climb, the search for effective treatments with few side-effects is critical. While SMT is the most commonly sought CAM treatment for LBP sufferers, there is only a small, albeit promising, body of research to support its use for patients with BRLP. This study seeks to fill a critical gap in the LBP literature by performing the first full scale RCT assessing chiropractic SMT for patients with sub-acute or chronic BRLP using important patient-oriented and objective biomechanical outcome measures. Low back pain (LBP) is well recognized as a significant individual and societal burden with lifetime prevalence estimates of up to 80%,[, ] contributing to rising health care costs in the United States that are now estimated to exceed $100 billion annually[ ]. Back-related leg pain (BRLP) is a common variation of LBP,[ – ] with lifetime prevalence estimates as high as 40%[ ]. A population-based survey from the Netherlands reported a one year prevalence of 13-24% for radiating leg symptoms[ ]. Often disabling, BRLP accounts for greater work loss, recurrences, and costs than uncomplicated LBP[ – ]. Further, the lifetime incidence of surgery is 10% for those with severe BRLP, compared to 1-2% for those with LBP[ ]. By far the most common reason for back surgery is herniated lumbar disc, a common cause of BRLP[ ]. In the US, half of those with back-related conditions seek complementary and alternative medicine (CAM) treatments, the most common of which is chiropractic care[, ]. While there is preliminary evidence suggesting chiropractic spinal manipulative therapy is beneficial for patients with BRLP, there is insufficient evidence currently available to assess the effectiveness of this care[, ]. Definition of Back-Related Leg Pain (BRLP) BRLP is defined as the constellation of symptoms characterized by unilateral or bilateral radiating pain originating in the lumbar region and traveling into the proximal or distal lower extremity with or without neurological signs[, ]. BRLP includes both radicular and nonradicular radiating pain. Radicular radiating pain is defined as pain caused by a lumbar nerve root lesion, resulting in pain radiating from the back into the dermatome of that root along the femoral or sciatic nerve distribution. Nonradicular radiating pain is defined as pain radiating from the back into the leg in a nondermatomal pattern[ ]. Etiology of Back-Related Leg Pain BRLP of radicular origin caused by lumbar nerve root irritation can be secondary to a variety of causes including one or more herniated lumbar discs[ ]. Disc herniation can lead to compression or traction of a nerve root and subsequent intra-neural inflammation[, ]. Inflammation may also be caused by biochemical mechanisms. For example, the breakdown products from a degenerating nucleus pulposis may leak into the epidural space and result in 'chemical radiculitis' of the nerve root[ ]. Other possible causes of lumbar nerve root irritation are spinal stenosis, nerve root canal narrowing, and synovial cysts[ ]. BRLP of nonradicular origin is caused by biomechanical dysfunction or pathological changes in the paraspinal muscles, ligaments, discs, facet joints, or other structures of the lumbar motion segments[ ]. Interventions Conservative or non-operative management is the first line of therapy for most BRLP patients[ ]. Surgery is a more costly treatment strategy and is only indicated in patients with progressive neurological deficits or unmanageable pain[ ]. Nicelabel serial number. Some of the most commonly used conservative approaches are physical treatments such as chiropractic spinal manipulative therapy[ ]. Chiropractic Spinal Manipulative Therapy (SMT) The most common reason patients pursue CAM treatments in the US is for back pain conditions[ ].
