WorkplaceTesting explains Lumbar

The lumbar region is the area where most back pain occurs. Approximately 80% of adults experience low back pain in their lifetime. Common causes of low back pain are sprains and strains, intervertebral disc degeneration, herniated discs, radiculopathy, spondylolisthesis, spinal stenosis, and skeletal irregularities. Individuals can also be predisposed to low back pain if they have a history of inflammatory diseases of the joints, osteoporosis, endometriosis, or fibromyalgia.

Occupational risk factors to developing low back pain include heavy lifting, pushing, pulling, and twisting or vibrating tasks, as well as sedentary work in poor postures. Low back pain causes are commonly diagnosed with an X-ray, MRI, CT scan, bone scan, or ultrasound imaging.
