The association between symptom severity and physical activity participation in people seeking care for acute low back pain

Return to self-reported physical activity level after an event of acute low back pain

Background

Regular physical activity participation is known to promote better mobility and coordination. Although previous research has established that lack of physical activity participation may increase the risk of developing low back pain, the role of physical activity as a predictor of recovery among symptomatic individuals remains unclear.

Objective

To evaluate whether: (i) the level of physical activity participation before an acute episode of low back pain predicts recovery within 12 months following the acute pain episode (i.e. index episode); and (ii) participants return to their pre-pain level of physical activity participation 12 months from the index episode.

Design

This study used longitudinal data from the TRIGGERS case-crossover study.

Setting

This study was conducted through over-the-phone interviews to participants that presented to 300 primary care clinics with a new episode of acute low back pain.

Participants

This study included 999 consecutive patients, aged 18 years or older. Follow-up assessment was completed at 12 months following the index episode.

Methods

This is a cohort study where consecutive patients, aged 18 years or older, that presented with a new episode of acute low back pain were recruited between October 2011 and November 2012.

Main outcome measurements

Self-reported level of physical activity participation.

Results

A total of 830 participants completed the study. When comparing participants who reported pain at 12 months follow-up with those without pain, all participants reported similar levels of physical activity participation one week before (p = 0.449), one week after (p = 0.812) and 12 months after the index episode (p = 0.233). The level of physical activity participation before the index episode was not a reliable predictor of presence of pain at either 3 or 12 months follow-up (OR 0.99; 95% CI 0.993 to 1.003; p = 0.523 and OR 1; 95% CI 0.992 to 1.008; p = 0.923, respectively).

Conclusion

Physical activity participation did not predict recovery from the pain episode. Also all participants returned to their pre-pain level of physical activity participation after 12 months.

A cross-sectional study of associations between kinesiophobia, pain, disability, and quality of life in patients with chronic low back pain

BACKGROUND

Low back pain is a significant health problem condition due to high prevalence among the general population. Emotions and physical factors are believed to play a role in chronic low back pain. Kinesiophobia is one of the most extreme forms of fear of pain due to movement or re-injury. The purpose of this study was to investigate the association between kinesiophobia and pain intensity, disability and quality of life in people with chronic low back pain.

METHODS

The study included 132 individuals with chronic back pain, with ages between 18 and 65 years old. Kinesiophobia was assessed using the Tampa Scale of Kinesiophobia, pain intensity was measured using the Numeric Rating Scale with a cut-off more than 3 for inclusion in the study, disability was assessed using the Roland Morris questionnaire, quality of pain was assessed using the McGill questionnaire, and quality of life was assessed using the Quality of Life questionnaire SF-36.

RESULTS

The results are statistically significant, but with weak associations were found between kinesiophobia and pain intensity (r = 0.187), quality of pain (sensory, r = 0.266; affective, r = - 0.174; and total r = 0.275), disability (r = 0.399) and physical quality of life (emotional r = - 0.414).

CONCLUSION

Kinesiophobia is an important outcome to assess in patients with chronic low back pain. The results suggest that correlations between kinesiophobia and disability and quality of life are statistically significant.

Low back pain in healthy postmenopausal women and the effect of physical activity: A secondary analysis in a randomized trial

Epidemiological studies on the prevalence of musculoskeletal pain have consistently shown that this is a relevant health problem, with non-specific low back pain (LBP) being the most commonly reported in adult females. Conflicting data on the association between LBP symptoms and physical activity (PA) have been reported. Here, we investigated the prevalence of LBP and the effect of a 24-month non-specific PA intervention on changes in LBP prevalence in a series of Italian healthy postmenopausal women. We performed a secondary analysis in the frame of the DAMA trial, a factorial randomized intervention trial aimed to evaluate the ability of a 24-month intervention, based on moderate-intensity PA, and/or dietary modification, in reducing mammographic breast density in healthy postmenopausal women. The PA intervention included at least 1 hour/day of moderate PA and a more strenuous weekly activity, collective walks and theoretical group sessions. A self-administered pain questionnaire was administered at baseline and at the end of the intervention. The questionnaire was specifically structured to investigate the occurrence of musculoskeletal pain, the body localization, intensity and duration of the pain. Two hundred and ten women (102 randomized to PA intervention, 108 not receiving the PA intervention) filled out the questionnaires. At baseline LBP was present in 32.9% of the participants. Among women randomized to the PA intervention, LBP prevalence at follow up (21.6%) was lower than at baseline (33.3%) (p = 0.02), while in women who did not receive the PA intervention the LBP prevalence at baseline and follow up were 32.4% and 25.9%, respectively (p = 0.30). Overall, there was no significant between-group effect of PA intervention on LBP. Further studies are needed to understand the role of non-specific PA intervention, aimed to improve overall fitness, on LBP prevalence.

[Formalized consensus: clinical practice recommendations for the management of acute low back pain of the African patient]

La lombalgie aiguë est la pathologie rhumatismale la plus fréquente en Afrique. L’épidémiologie et la présentation clinique ne diffèrent pas de celles observées sur les autres continents. En revanche, les aspects psycho-sociaux, la disponibilité des traitements, l'accès aux soins et le poids culturel des médecines traditionnelles sont autant de spécificités qui ont conduit à la réalisation du 1er consensus d'experts en rhumatologie pour la prise en charge du patient africain. Destiné aux praticiens, ce travail collaboratif multinational a pour objectif de fournir 11 recommandations de pratiques cliniques simples, fondées sur les preuves, et adaptées aux conditions de l'exercice médical en Afrique. Leur ambition est d'améliorer la prise en charge de la lombalgie aigue par une évaluation initiale clinique pertinente, une diminution des examens radiologiques inutiles, une prescription médicamenteuse adéquate et l'abandon de procédures invasives inappropriées.
