Exploring Multidimensional Trajectories in People With Low Back Pain

Обзор

Low back pain (LBP) is a major health problem in Switzerland and worldwide. Globally, LBP remains the leading cause of years lived with disability and its incidence and associated socioeconomic consequences are predicted to increase in the coming decades. In Switzerland, the condition is one of the most commonly reported physical complaints and negatively affects quality of life, resulting in significant personal burden and personal financial burden. LBP also generates enormous socioeconomic costs, with both direct and indirect costs estimated to reach billions of Swiss francs in Switzerland annually. Therefore, it is essential that LBP prevention, diagnosis, and management are improved. LBP is a multifactorial condition. Social, psychological and biophysical factors, along with comorbidities and genetic factors, influence LBP development and associated disability. In individuals with LBP, psychological factors, such as pain catastrophizing, are associated with higher pain intensity and developing chronic LBP and the associated disability. Among biophysical factors, altered spinal motor behaviour (e.g. smaller trunk movement amplitude) and reduced physical activity have been observed in LBP patients and suggested to influence LBP. However, exactly how all these factors influence LBP and how they are interrelated remains unclear. In particular, the effect of altered spinal motor behaviour on LBP is not understood. However, altered motor behaviour could play an important role in changing LBP and related disability. Therefore, improving our understanding of the patterns of spinal motor behaviour and the interrelationships with other factors in LBP would increase our understanding of LBP progression and could help improve LBP management. This study consists of a 6-month prospective longitudinal cohort observation of spinal motor behavior, physical activity, psychological factors, pain intensity, and disability in LBP patients (300 acute, 300 chronic LBP). Data collection will occur remotely and the frequency of repeated measures will be daily or weekly, depending on the measure. A custom smart-phone application will be used by participants to collect data on spinal motor behavior, psychological factors, pain intensity, and disability. Physical activity will be monitored using a wearable physical activity tracker. Established trajectories of motor behavior will be investigated for potential interrelations with trajectories of other parameters (e.g. pain, psychological factors, and disability), to explore potential causal effects. In addition, risk factors or predictive factors for certain trajectories of motor behavior and other parameters will be identified. As such, this study will allow us to investigate the temporality of these relationships and identify LBP, and in particular spinal motor behavior, phenotypes.
