| Abstract: | AbstractA previous study compared socio-demographic characteristics, health problem characteristics, and primary process data between a database sample of patients referred to physical therapy (PT) versus a sample of patients referred for specific manual physical therapy (MPT) diagnosis and management. This study did not differentiate between patients based on affected body region or diagnosis. The present study is a secondary analysis of these data for patients with non-specific low-back pain (LBP). Statistical analysis indicated that the MPT patient sample was significantly (P<0.01) different from the PT database sample with regard to socio-demographic data: The MPT patients were more often male, younger, had attained a higher level of post-secondary education, and were more often gainfully employed. The MPT sample was also significantly (P<0.01) different from the PT sample with regard to health problem characteristics indicating more often acute, recurrent, non-surgical LBP of shorter duration and unknown etiology in the MPT sample. Both samples were also significantly different with regard to the most common impairments, limitations in activities, and restrictions in participation. After correction for socio-demographic differences, both samples remained significantly different for pathology, recurrence, and mechanism of injury. Diagnosis and management with MPT resulted in a significantly better outcome at discharge than PT as determined by the therapist based on patient verbal report (P=0.0000); however, data on recurrence and the unclear influence of socio-demographic data as well as the absence of more reliable, valid, and responsive outcome measures render these outcome data somewhat equivocal. Interpretation of these data with regard to their potential use in diagnostic classification of patients with non-specific LBP is discussed. |
