Symmetry of paraspinal muscle denervation in clinical lumbar spinal stenosis: support for a hypothesis of posterior primary ramus stretching?

Introduction: Denervation of the paraspinal muscles in spinal disorders is frequently attributed to radiculopathy. Therefore, patients with lumbar spinal stenosis causing asymmetrical symptoms should have asymmetrical paraspinal denervation.

Methods: Seventy-three patients with clinical lumbar spinal stenosis, aged 55-85 years, completed a pain drawing and underwent masked electrodiagnostic testing, including bilateral paraspinal mapping and testing of 6 muscles on the most symptomatic (or randomly chosen) limb.

Defining the clinical syndrome of lumbar spinal stenosis: a recursive specialist survey process.

Background: Lumbar spinal stenosis has evolved from an anatomic concept to a poorly defined clinical syndrome. Rules for such a syndrome need to be informed by the experience and beliefs of expert clinicians. The level of certainty is seldom considered in defining criteria for a syndrome.

Sleep and quality of life in children with cerebral palsy.

Objective: To examine the associations between sleep problems and quality of life (QoL) in children with cerebral palsy (CP).

Methods: Prospective correlational study using parent-report forms to measure QoL and sleep disorder symptoms. Two groups comprised of 41 children with CP and 91 typically developing (TD) controls age 8-12years participated in a prospective correlational study.
