Abstract
Background and objective
Clinical guidelines recommend physical activity to manage neck pain (NP) and low back pain (LBP). However, studies used to support these guidelines are based on self‐reports of physical behaviour which are prone to bias and misclassification. This systematic review aimed to investigate associations between objectively measured physical behaviour and the risk or prognosis of NP and/or LBP.
Databases and data treatment
Literature searches were performed in MEDLINE, Embase, and Scopus from their inception until January 18th, 2019. We considered prospective cohort studies for eligibility. Article selection, data extraction, and critical appraisal were carried out by independent reviewers. Results were stratified on activity/sedentariness.
Results
Ten articles out of 897 unique records identified met the inclusion criteria, of which eight studied working populations with mainly blue‐collar workers. The overall results indicate that increased sitting time at work reduces the risk of NP and LBP while increased physical activity during work and/or leisure increases the risk of these conditions among blue‐collar workers; however, associations were weak. Physical activity was not associated with prognosis of LBP (no studies investigated prognosis of NP). Most of the included articles have methodological shortcomings.
Conclusions
This review indicates that, among blue‐collar workers, increased sitting at work may protect against NP and LBP, while increased physical activity during work and/or leisure may increase this risk. There was no evidence supporting physical activity as a prognostic factor for LBP. Findings should be interpreted with caution due to the weak associations and few available studies with methodological shortcomings.
