- 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

- 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
