EFFECT OF PSYCHOLOGICAL STATUS ON THE OUTCOME OF A SPINAL FITNESS EXERCISE PROGRAM

Abstract

Study Design: Prospective analysis of a cohort of patients who underwent a Spinal Fitness Exercise Program in a nurse led spinal assessment clinic in a University Hospital.

Objective: To determine if psychological status affects the outcome of a spinal fitness exercise program in patients with low back pain.

Background: Evidence for the effectiveness of exercise programs in the treatment of chronic mechanical low back pain is well documented. In this study, the effect of psychological status on the outcome of a self-help spinal fitness exercise programme was studied.

Methods: Patients who were referred by their primary care physicians to the nurse led spinal assessment clinic and met the inclusion criteria were given a spinal exercise booklet, which describes with the aid of diagrams how to perform a series of lumbar core stability exercises for them to practise at home. Back pain related disability was assessed before and 3 months after the exercise program using the Oswestry Disability Index (ODI). Psychological status was measured using the Distress and Risk Assessment Method (DRAM). This classifies patients into 4 groups based on the combination of scores from the Modified Somatic Perception Questionnaire (MSPQ, 13 questions, scored 0–13) and Modified Zung Questionnaire (23 questions scored 0–69): normal, at risk, distressed somatic and distressed depressive.

Results: Forty one patients were enrolled into the study (19 male, 22 female, mean age at treatment 45.8 years, age range 22–78 years). The DRAM scores showed that 9 had no psychological disturbance (normal), 17 were at risk, 4 were distressed somatic and 11 distressed depressive. Even though there was a statistically significant improvement in the mean ODI after the exercise program for all DRAM groups, the improvement in the ODI was not significantly different between the four groups (ANOVA, p = 0.596).

Conclusions: Our study suggests that the outcome of a spinal fitness exercise programme is not affected by the psychological status of the patient. We conclude that patients should not be excluded from spinal fitness exercise programs on the basis of psychological status.
