[Recommendations for functional evaluation and rehabilitation of chronic low back pain]. / Recommandations pour l'évaluation et la rééducation fonctionnelles du patient souffrant d'une lombalgie chronique.

The majority of non-specific low back pain has a favourable evolution within a short period of time but in some cases the pain becomes persistent or recurrent. These chronic forms are responsible for most of the social and economic burden of low back pain. The crucial role of psycho-social factors in the chronicisation of low back pain justifies a thorough bio-psycho-social assessment. An active semi-intensive ambulatory multidisciplinary programme (Spine Unit Center) that complies with international and national recommendations (KCE and INAMI) has demonstrated its effectiveness in chronic low back pain in terms of algo-functional, physical and psycho-social components. In contrast to intensive programmes requiring hospitalisation, this outpatient treatment allows the patient to remain in his/her social and professional network. The active participation and motivation of the patient are essential for the success of the treatment. The multidisciplinary team will help the patient to define his/her functional objectives and to manage, via the psychologist, emotional aspects. The programme includes therapeutic education and physical reconditioning sessions including progressive aerobic training, group exercises, and individualised and progressive strengthening of the trunk muscles. The introduction of physical activity at home will be encouraged in order to sustain the changes in the patient's behaviour.

La majorité des lombalgies non spécifiques présente une évolution favorable dans un délai assez court, mais, dans certains cas, les douleurs deviennent persistantes ou récurrentes. Ces formes chroniques sont responsables de l'essentiel du poids social et économique des lombalgies. Le rôle crucial des facteurs psycho-sociaux dans la chronicisation de la lombalgie justifie une évaluation bio-psycho-sociale approfondie. Un programme pluridisciplinaire ambulatoire actif semi-intensif («Clinique du Dos¼) répondant aux recommandations internationales et nationales (KCE et INAMI) a démontré une efficacité sur les composantes algo-fonctionnelles, physiques et psycho-sociales du patient lombalgique chronique. Contrairement aux programmes intensifs imposant une hospitalisation, cette prise en charge ambulatoire permet au patient de rester dans son réseau social et professionnel. La participation active et la motivation du patient constituent les éléments essentiels pour la réussite du traitement. L'équipe pluridisciplinaire l'aidera à définir ses objectifs fonctionnels et à gérer, via le psychologue, certains aspects émotionnels en lien avec la douleur. Le programme comprend des séances d'éducation thérapeutique et de reconditionnement physique, incluant un entraînement aérobie progressif, une gymnastique collective de tonification et un renforcement individualisé et graduel des muscles du tronc. L'instauration d'une activité physique à domicile sera encouragée de manière à pérenniser les changements de comportement du patient.

Complementary treatment comparison for chronic pain management: A randomized longitudinal study.

BACKGROUND: In chronic pain, it seems that the effect of cognitive-behavioral therapy (CBT) is boosted when it is combined with hypnosis. The aim of this study was to assess the efficacy of self-hypnosis combined with self-care (i.e., a type of CBT) compared to music/self-care, self-care and psychoeducation/CBT and to evaluate their long-term effects. METHODS: An open label randomized clinical trial enrolled patients with chronic pain and was carried out at the University Hospital of Liège (Belgium). Patients were randomized into four groups: self-hypnosis/self-care, music/self-care, self-care, psychoeducation/CBT (7 monthly sessions of 2 hours). Two follow-up sessions were delivered at 6- and 12-month. Levels of pain, fatigue intensity, anxiety, depression, insomnia severity, disability, health locus of control, mental and physical quality of life and attitudes (control, disability, harm, emotion, medical cure, medication, solicitude) towards pain were assessed before and after the treatments, and at follow-up. RESULTS: 203 patients were randomized: 52 in self-hypnosis/self-care, 59 in music/self-care, 47 in self-care, and 45 in psychoeducation/CBT. No group effect was found. A significant time effect was showed. Directly after the treatment, all groups decreased in pain attitudes and physical quality of life. Perceived control increased. At 6-month, all patients kept their levels of physical quality of life and perceived control, and showed decrease in pain intensity, harm, emotion and medical cure. At 12-month, scores that had change previously remained ameliorated, a decrease in insomnia severity and an increase in internal locus of control were observed. CONCLUSIONS: The present findings are encouraging as they display long-term beneficial effects of complementary biopsychosocial-based treatments in chronic pain. It seems that patients continued to apply the learnt strategies as improvements were observed one year after the treatments had ended.

Drop-out from chronic pain treatment programmes: Is randomization justified in biopsychosocial approaches?

OBJECTIVE: To identify profiles of patients who are at risk of dropping out from biopsychosocial approaches to chronic pain management. PATIENTS: A total of 575 patients were included in the study. Of these, 203 were randomized into 4 treat-ment groups: self-hypnosis/self-care; music/self-care; self-care; and psychoeducation/cognitive behavioural therapy. The remaining 372 patients were not randomized, as they presented with the demand to learn self-hypnosis/self-care, and therefore were termed a "self-hypnosis/self-care demanders" group. METHODS: Socio-demographics and behavioural data were included in the analyses. Univariates analyses, comparing early drop-outs (never attended treatment), late drop-outs (6/9 sessions' treatment) and continuers were conducted in order to select variables to include in a multivariate logistic regression. RESULTS: Univariate analyses yielded 8 variables, out of 18 potential predictors for drop-out, which were eligible for inclusion in the multivariate logistic regression. The model showed that having an intermediate or high educational level protects against dropping out early or late in the pain management process. Having to wait for more than 4 months before starting the treatment increases the risk of never starting it. Being randomized increases the risk of never starting the treatment. CONCLUSION: In a context in which randomization is considered a "gold standard" in evidence-based practice, these results indicate that this very principle could be deleterious to pain management in patients with chronic pain.

Psychological interventions influence patients' attitudes and beliefs about their chronic pain.

BACKGROUND: Patients' changing attitudes and beliefs about pain are considered as improvements in the treatment of chronic pain. Multidisciplinary approaches to pain allow modifications of coping strategies of patients, from passive to active. METHODS: We investigate how two therapeutic treatments impact patients' attitudes and beliefs regarding pain, as measured with the Survey of Pain Attitudes (SOPA). We allocated 415 patients with chronic pain either to psychoeducation combined with physiotherapy, self-hypnosis combined with self-care learning, or to control groups. Pain intensity, global impression of change, and beliefs and attitudes regarding pain were assessed before and after treatment. RESULTS: Our main results showed a significant effect of psychoeducation/physiotherapy on control, harm, and medical cure SOPA subscales; and a significant effect of self-hypnosis/self-care on control, disability and medical cure subscales. Correlation results showed that pain perception was negatively associated with control, while positively associated with disability, and a belief that hurt signifies harm. Patients' impression of improvement was associated with greater control, lower disability, and lower belief that hurt signifies harm. CONCLUSIONS: The present study showed that self-hypnosis/self-care and psychoeducation/physiotherapy were associated with patients' evolution of coping strategies from passive to active, allowing them to reduce pain perception and improve their global impression of treatment effectiveness.

Relationship between different measures of pain-related fear and physical capacity of the spine in patients with chronic low back pain.

BACKGROUND CONTEXT: It has been controversially stated that pain-related fear is a more important determining factor for disability in chronic low back pain (CLBP) than pain or physical impairment in itself. So far, the relationship between psychological and physiological determinants of chronic pain, that is, pain-related fear and physiological abilities, remains unclear. PURPOSE: To evaluate whether pain-related fear assessed by different tools (both task specific and non task specific) is related to physical capacity measured by specific spine tests and, secondarily, to explore the relationship between different pain-related fear assessment tools. STUDY DESIGN/SETTING: Cross-sectional study. PATIENT SAMPLE: Fifty patients with CLBP (50% women; meanage [standard deviationage]: 44.2 [9.5 years]). OUTCOME MEASURES: Physical capacity by means of three specific spine tests, that is, the finger-floor distance test (flexibility), a maximal isometric strength test of trunk extensor muscles (strength), and the Sorensen test (endurance). Pain-related fear by means of self-report measures, that is, the Tampa Scale for Kinesiophobia (TSK), the Photograph Series of Daily Activities (PHODA), and a fear visual analog scale (FVAS) tailored to the spine tests. METHODS: Participants were asked to complete the TSK and PHODA and to perform the three spine tests. Right before performing each of the spine tests, an FVAS was filled out. Linear regression analyses controlling for gender and age were performed to study the association between the pain-related fear measurements and the results of the spine tests. To investigate the relationship between the pain-related fear measurements, correlation tests were performed. RESULTS: The linear regression analyses revealed that neither the TSK and PHODA scores nor the FVAS scores were significantly related to the physical capacity measurements. The correlational tests showed no significant correlation between the PHODA, TSK, and FVAS scores. CONCLUSIONS: The present study shows that neither the task-specific tool (FVAS) nor the non task-specific questionnaires (TSK and PHODA) were significantly correlated to the spine tests in patients with CLBP. This is contrary to earlier evidence according to which physical capacity is inversely related to the level of pain-related fear, and it suggests that one should not draw conclusions about physical capacity based on pain-related fear scores. Furthermore, the different assessment tools for pain-related fear were surprisingly not correlated with each other.
