Management of back and neck pain: who seeks care from physical therapists?

Abstract

Background and purpose: Little information is available on factors associated with physical therapist use by people with back or neck pain. Identifying the characteristics of people who seek care from physical therapists is a useful first step in determining whether there is appropriate use of physical therapy services. The purpose of this study was to identify factors associated with physical therapist use by people with back or neck pain.

Subjects: The subjects were 29,049 people who had back pain or neck pain, or both, and who were seen for an initial evaluation at 1 of 21 US spine care centers. Each subject and evaluating physician completed a written survey at the time of the initial evaluation.

Methods: Multiple logistic regression analyses were conducted to identify factors associated with physical therapist use.

Results: Several measures of health and illness severity were associated with physical therapist use. Age and being male were negatively associated with physical therapist use. Education level, having workers' compensation coverage, and being in litigation were positively associated with physical therapist use. Physical therapist use also varied by previous physician use and census region.

Discussion and conclusion: The results suggest that variations in physical therapist use are associated with factors other than health and illness severity. The results also suggest that people who would benefit from physical therapy may not be receiving it or that people who would not benefit from physical therapy are receiving it, or both.
