Quantitative sensory testing changes in the successful management of chronic low back pain.

Individuals with chronic low back pain (LBP) represent a significant percentage of patients in physical therapy practice. The clinical pattern often includes diffuse pain and a variety of sensory complaints, making categorization difficult and leading to diagnoses such as non-specific LBP. Objective measures of sensory changes through quantitative sensory testing may help identify central sensitization of nociceptive pathways in this population. Identification of these somatosensory changes may contribute to clinical decision making and patient management. The purpose of this case report is to present objective evaluation findings, including altered somatosensation, in a patient with a 2-year history of LBP, and to describe changes in function and quantitative sensory testing with successful management.
