A Comparison of Two Different Methods of Physical Therapy to Treat Acute and Subacute Low Back Pain

Recent research has shown that classifying patients with low back pain into treatment subgroups results in better improvements than treating all patients with low back pain the same. However, physical therapists may use different types of information to determine how to classify their patients. One method uses patient characteristics that have been shown by research to predict good results from a certain type of treatment. Another method uses specific impairments that the physical therapist identifies in a clinical exam to determine which treatment to provide. It is not currently known if one of these methods is better than the other. The purpose of this study is to determine if research-based classification or impairment-based treatment is more effective for treating patients with low back pain that has lasted less than 90 days in terms of improvements in pain and disability. The results of this study may help reduce the high financial cost associated with low back pain.
