Association of incipient disc degeneration and instability in spondylolisthesis. A magnetic resonance and flexion-extension radiographic study of 20-year-old low back pain patients.
The concurrence of early disc degeneration and abnormal segmental motion in spondylolysis of young low back pain patients (n = 14) was investigated using magnetic resonance imaging (MRI) and flexion-extension radiography. Seven patients with L5 spondylolisthesis had normal discs on MRI and 7 had disc degeneration below the slipped vertebra. ⋯ The present study shows that in adolescents the motion pattern and hydration of discs associated with spondylolysis and spondylolisthesis are not always abnormal. The early dehydration and degeneration of lumbar discs observed on MRI are not always associated with abnormal mobility of the corresponding motion segment.

Comparative Study
A comparison of two-point discrimination threshold of tactual, non-painful stimuli between chronic low back pain patients and controls.
Differences in pain sensitivity between chronic pain patients and healthy controls have been reported. Seltzer and Seltzer extended this line of research in studying the sensitivity to non-painful stimuli. They reported that the 2-point discrimination threshold of chronic pain patients was higher than that of control subjects. ⋯ Therefore, in the present study we tried to replicate the findings in a group of chronic low back pain patients using a design that was believed to be methodologically stronger. Replication failed: no evidence was found for the hypothesis that chronic pain patients are less sensitive to non-painful stimuli. Further studies on various defined types of acute and chronic pain patients are required.

Associations between the frequency of medical visits and psychological disturbance were explored using chronic low back pain patients from a back education class. Psychometric measures included the illness Behaviour Questionnaire (IBQ), somatic problems, and current mood. ⋯ Additional predictors for specialist visits included a self-rated pain/mood association, sex, age, and IBQ denial. Patients' expectations and attitudes about illness and treatment appeared most central to medical visits and several different forms of psychological disturbance accompanied increased visits.

The aim of this prospective study was to follow the pain and discomfort among dentists in the Public Dental Service in Malmöhus District and the Municipality of Malmö. In this investigation 311 dentists, who had answered questionnaires in 1987 and in 1990, took part. The prevalence of musculoskeletal pain and discomfort had increased, except the lower back pain and headache. ⋯ Of the 262 dentists with symptoms in 1987 twenty-four were without symptoms at the follow-up in 1990. The aim of the investigation was also to study the influence of some ergonomic factors on the course of symptoms. However, these ergonomic variables showed a low predictive value for recovery or for the development of pain and discomfort in the locomotor system.

Personality traits in patients with acute low-back pain. A comparison with chronic low-back pain patients.
This study investigates the possibilities to identify, within a group of acute low-back pain patients, individuals with psychogenic etiology to pain. 26 acute back pain patients and 25 healthy control subjects were tested with the Minnesota Multiphasic Personality Inventory Hysteria: (Hs), Hypochondria (Hy), Depression (D); Cesarek-Marke Personality Scale: Aggression (Agg), Defence of status (Dst), Guilt (Gui); Mood Adjective Check List: (Hedonism, Activity, Calmness = Hed, Act, Clm) and a 'pain questionnaire' including 'pain drawing'. Differences between groups and correlation patterns between test variables indicate that a combination of Hs, Hy, D, Dst, Gui, Hed, Act, Clm as well as predisposition to somatization, Som (a quantification of pain drawing) provides a useful predictive screening instrument.
