MMPI-2 profiles and illness perception in fibromyalgia syndrome: The role of therapeutic exercise as adapted physical activity

Abstract

BACKGROUND:

Control of pain management is an important up-stream process in fibromyalgia (FM) mechanisms.

OBJECTIVE:

To investigate whether adapted physical activity (APA) could change the illness perception in relation to the FM personality profile.

METHODS:

Thirty-seven women with FM allocated randomly: 19 treatment group (TG) and 18 control group (CG). Interventions: exercises program included ten sessions, two times for week for one hour each and observation for CG. Scales: Illness Perception Questionnaire-revisited (IPQ-r) for the mental representation of the disease, Minnesota Multiphasic Personality Inventory profiles (MMPI-2) for personality tool and Fibromyalgia Impact Questionnaire (FIQ) for function, impact and symptoms. Outcome assessments were performed before rehabilitation treatment (T0) than at the end (T1), and a follow-up 12 weeks after treatment (T2).

RESULTS:

APA was efficacy to improve FIQ values in TG at T1 and T2 test days ( $\mathit{P}=0.014$ ). Changes in IPQ-R values in T2 were not significant. All patients presented a baseline T-score ≥ 65 in at least one of the basic and content MMPI-2 scales (Hy, D, Hs and Hea and Anx).

CONCLUSION:

APA was efficacy in FM, but further research to differentiate between illness experience rather than focus on a strict personality profile are necessary.
