“…27 This is supported by findings of earlier studies identifying poor social relationships being a risk factor for pain chronification. 41,45 Vital exhaustion as a sign of stress-related fatigue turned out to predict pain intensity at 1-year follow-up, but not disability. At 2-years follow-up, this link was not found.…”

Purpose: Psychosocial variables are known risk factors for the development and chronification of low back pain (LBP). Psychosocial stress is one of these risk factors. Therefore, this study aims to identify the most important types of stress predicting LBP. Self-efficacy was included as a potential protective factor related to both, stress and pain. Participants and Methods: This prospective observational study assessed n = 1071 subjects with low back pain over 2 years. Psychosocial stress was evaluated in a broad manner using instruments assessing perceived stress, stress experiences in work and social contexts, vital exhaustion and life-event stress. Further, self-efficacy and pain (characteristic pain intensity and disability) were assessed. Using least absolute shrinkage selection operator regression, important predictors of characteristic pain intensity and pain-related disability at 1-year and 2-years follow-up were analyzed. Results: The final sample for the statistic procedure consisted of 588 subjects (age: 39.2 (±13.4) years; baseline pain intensity: 27.8 (±18.4); disability: 14.3 (±17.9)). In the 1-year follow-up, the stress types "tendency to worry", "social isolation", "work discontent" as well as vital exhaustion and negative life events were identified as risk factors for both pain intensity and pain-related disability. Within the 2-years follow-up, Lasso models identified the stress types "tendency to worry", "social isolation", "social conflicts", and "perceived long-term stress" as potential risk factors for both pain intensity and disability. Furthermore, "self-efficacy" ("internality", "self-concept") and "social externality" play a role in reducing pain-related disability. Conclusion: Stress experiences in social and work-related contexts were identified as important risk factors for LBP 1 or 2 years in the future, even in subjects with low initial pain levels. Self-efficacy turned out to be a protective factor for pain development, especially in the long-term follow-up. Results suggest a differentiation of stress types in addressing psychosocial factors in research, prevention and therapy approaches.

“…Other studies suggest to utilise measures of the kinematics of the trunk (Balaguier et al 2017;LagerstedOlsen et al 2016;Lunde et al 2017;Robert-Lachaine et al 2017;Villumsen et al 2016) or a combination of these methods (Samani et al 2012). So far, most studies based on in situ assessments have studied bending and torsion of the trunk but have not provided assessments of the physical loads (Balaguier et al 2017;Villumsen et al 2015Villumsen et al , 2016. The current body of literature reinforces the need for direct objective measures enabling delineation of lifts with low or high risk of contracting low back injuries.…”

The aim was to classify lifting activities into low and high risk categories (according to The Danish Working Environment Authority guidelines) based on surface electromyography (sEMG) and trunk inclination (tri-axial accelerometer) measurements. Lifting tasks with different weights, horizontal distance and technique were performed. The lifting tasks were characterised by a feature vector composed of either the 90th, 95th or 99th percentile of sEMG activity level and trunk inclinations during the task. Linear Discriminant Analysis and a subject-specific threshold scheme were applied and lifting tasks were classified with an accuracy of 65.1-65.5%. When lifts were classified based on the subject-specific threshold scheme from low and upper back accelerometers, the accuracy reached 52.1-58.1% and 72.7-78.1%, respectively. In conclusion, the use of subject-specific thresholds from sEMG from upper trapezius and erector spinae as well as inclination of the upper trunk enabled us to identify low and high risk lifts with an acceptable accuracy.Practitioner Summary: This study contributes to the development of a method enabling the automatic detection of high risk lifting tasks, i.e. exposure to high biomechanical loads, based on individual sEMG and kinematics from an entire working day. These methods may be more costeffective and may complement observations commonly used by practitioners.

Knowledge about the time course of neck-shoulder pain (NSP) among workers is sparse. Latent class growth modeling was used to distinguish NSP trajectories based on repeated measurements over one year. Six distinct pain trajectories were identified. Pain characteristics, personal and occupational factors predicted severe persistent NSP. The study contributes with novel information about the time course of NSP among workers.
