Does objectively measured daily duration of forward bending predict development and aggravation of low-back pain? A prospective study

Abstract

This study is the first to investigate the association between objectively measured duration of forward bending and the prospective development and aggravation of low-back pain among blue-collar workers. This study shows no significant association. Future studies in the cohort will investigate the contribution of possible effect modifiers such as psychosocial work factors and physical capacity.Affiliation:

Trunk kinematics and low back pain during pruning among vineyard workers—A field study at the Chateau Larose-Trintaudon

“…Vineyard-workers were asked to rate their pain intensity using a 0–10 numeric rating scale (0:”No pain”, 10: “Worst imaginable pain”) [25,31] every working day over the 2 weeks prior data collection. The mean of these ratings was used for data analysis enabling to assess the relationship between trunk kinematics and the pain intensity representing a proxy of the pain commonly reported in the low back region by the participants from the Chateau Larose-Trintaudon (France).…”

“…Second, it did not assess the association between physical exposure and risk of LBP among vineyard-workers, while numerous studies have highlighted the need to evaluate more precisely this association using objective and quantitative field measurements [16,29,30]. As mentioned in numerous studies [31,32], one valid approach to quantify the risk of LBP among workers is to assess the relationship between duration of forward bending and self-reported LBP intensity, e.g. using numeric pain rating scale (NRS).…”

Effects of a Participatory Ergonomics Intervention With Wearable Technical Measurements of Physical Workload in the Construction Industry: Cluster Randomized Controlled Trial (Preprint)

“…Technological development has made it possible to obtain field measurements with surface electromyography (sEMG) [10,11], kinematics measured with inertial measurement unit (IMU) [12][13][14][15], or a combination [16]. However, no studies have used sEMG, IMU and video recordings obtained simultaneously to detect events with excessive physical workload (events) during a working day.…”
