Eligibility Criteria | Inclusion Criteria: - Non-radicular LBP pain for ≤12 months (non-radicular defined as LBP that does not radiate below the mid-buttock and with no sensory symptoms in the leg) - Had LBP as the primary source of pain. Patients may have had mild to moderate spinal stenosis and no radicular symptoms - Had an average daily pain intensity score of >4 on a 0 to 10 scale, with 0 being no pain and 10 being pain as bad as the patients have ever imagined (Question 5 of BPI) within 24 hours prior to the screening visit. - Had a normal neurological examination, including: - Motor strength - Sensory testing (light touch, pinprick, and vibration) - Deep tendon reflexes Patients were eligible for participation in the long-term chronic (>12 months) group of the study if they also: - Had LBP for greater than one year. Patients may have had any of the following: lumbar degenerative disc disease, internal disc disruption, mild-to-severe spinal stenosis, degenerative scoliosis and spondylolisthesis, facet arthropathy Exclusion Criteria: - Had a history of greater than one back surgery or one back surgery within 3 months of study entry - Had severe spinal stenosis and radicular symptoms - Had any other chronic pain condition that, in the opinion of the investigator, would have interfered with patient assessment of LBP relief - Had received an epidural steroid/local anesthetic injection within 2 weeks prior to study entry - Had received trigger point injections within 2 weeks prior to study entry - Had received Botox Injections within 3 months prior to study entry - Were taking a lidocaine-containing product that could not be discontinued while receiving Lidoderm - Were taking class 1 anti-arrhythmic drugs (e.g., mexiletine, tocainide) Patients were excluded from participation in the long-term chronic (>12 months) group if they also: - Had an undefined spinal diagnosis - Had a history of lumbar spine surgery within 6 months prior to study entry |
