Psychological disturbance and pain report differences in both organic and non-organic low back pain patients.
Patients with undiagnosable low back pain have been observed to differ from patients with proven low back pain in their clinical description of pain and in their psychological status. More variable and diffuse pain qualities are emphasized in their clinical reports and more psychological disturbance characterizes them as a group, suggesting an association between pain expression and psychological disturbance. One hundred and two patients with low back pain were administered a standardized pain questionnaire to determine more systematically the association between pain expression and psychological disturbance in patients with and without demonstrable organic disease. Patients with psychological disturbance differed significantly from patients without psychological disturbance in the following ways. They used more words in their description of pain, distributed these words over more pain factors, and endorsed significantly more pain of the affective and skin pressure variety. The results underscore previous clinical impressions and suggest that patients without either organic or psychological findings may be cases of undiagnosed organic disease.
