“…For instance, vineyard workers spent 50% of the 12 minutes working time with the trunk rotated >10° for pruning. Similar rotated trunk postures have been previously observed among other workers such as sheep shearers [48] or paramedics [49]. However, during the 12 minutes of pruning activity, vineyard-workers spent significantly most of the time with the trunk rotated to the left side for all cut-off angles (i.e.…”

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

The prevalence of low back disorders is dramatically high in viticulture. Field measurements that objectively quantify work exposure can provide information on the relationship between the adopted trunk postures and low back pain. The purposes of the present study were three-fold (1) to carry out a kinematics analysis of vineyard-workers’ pruning activity by extracting the duration of bending and rotation of the trunk, (2) to question separately the relationship between the duration of forward bending or trunk rotation with low back pain intensity and pressure pain sensitivity and (3) to question the relationship between the combined duration of forward bending and trunk rotation on low back pain intensity and pressure pain sensitivity. Fifteen vineyard-workers were asked to perform pruning activity for 12 minutes with a wireless triaxial accelerometer placed on their trunk. Kinematic analysis of the trunk showed that vineyard-workers spent more than 50% of the time with the trunk flexed greater than 30° and more than 20% with the trunk rotated greater than 10°. These results show that pruning activity lead to the adoption of forward bended and rotated trunk postures that could significantly increase the risk of work related musculoskeletal disorders in the low back. However, this result was mitigated by the observation of an absence of significant association between the duration of forward bending and trunk rotation with low back pain intensity or pressure pain sensitivity. Even if prospective field measurements and studies assessing the effects of low back pain confounders are needed, this field study provides new genuine information on trunk kinematics during pruning activity.

“…The most prevalent risks are from the ergonomic risk of physical overexertion [ 5 , 6 ] and from psychosocial factors [ 3 , 7 – 11 ]. For both types of risk, a higher incidence of exposure among MT workers compared to other groups of the active population has been observed [ 3 , 11 ].…”

BackgroundMedical transport (MT) professionals are subject to considerable emotional demands due to their involvement in life-or-death situations and their exposure to the serious health problems of their clients. An increase in the demand for MT services has, in turn, increased interest in the study of the psychosocial risk factors affecting the health of workers in this sector. However, research thus far has not distinguished between emergency (EMT) and non-emergency (non-EMT) services, nor between the sexes. Furthermore, little emphasis has been placed on the protective factors involved. The main objective of the present study is to identify any existing differential exposure – for reasons of work setting (EMT and non-EMT) or of gender – to the various psychosocial risk and protective factors affecting the health of MT workers.MethodsDescriptive and transversal research with responses from 201 professionals.ResultsThe scores obtained on the various psychosocial scales in our study – as indicators of future health problems – were more unfavourable for non-EMT workers than they were for EMT workers. Work setting, but not gender, was able to account for these differences.DiscussionThe scores obtained for the different psychosocial factors are generally more favourable for the professionals we surveyed than those obtained in previous samples.ConclusionThe significant differences observed between EMT and non-EMT personnel raise important questions regarding the organization of work in companies that carry out both services at the same time in the same territory. The relationships among the set of risk/protective factors suggests a need for further investigation into working conditions as well as a consideration of the workers’ sense of coherence and subjective well-being as protective factors against occupational burnout syndrome.

“…The use of the threshold value for anterior / posterior shear with a limit of 700 N for repetitive manual handling material and 1000 N for non-repetitive handling material handling (Gallagar & Marras, 2012) is also used in the study of lifting of patients into the ambulance (Prairie et al 2014;Labaj et al, 2016). Other studies used the allowable anterior/posterior shear limit of 500 N from McGill (Harris- Adamson et al, 2016) for exciting or encouraging work.…”

Material handling manual work is a job at risk to worker health and safety, errors in the manual procedure of manual material handling will result in health impacts in the short and long term. One of the manual jobs of material handling is the job of lowering the sand from the top of the truck. In working the workers use a tool in the form of enggrong which is a shovel with a short handle. Due to the use of employee enggrong work with a stooped posture. This work posture raises the potential for low back pain on workers. Low back pain is a pain and/or loss of workability as a long-term risk of postural errors in activity. Low back pain occurs on low back disc L4 / L5 or L5 / S1. This study used treatment by the same subject design with a sample of 9 participants. The purpose of the study was to find out the different forces in Low back disc L4 / L5 when the worker worked using standard enggrong (Period 1 / P1) compared to using modification enggorong (Period 2 / P2). The forces in the L4 / L5 Low back disc include 1) compression, 2) anterior/posterior shear, and 3) lateral shear. Work posture data was taken using Microsoft KinectTM 3D camera and analyzed by using Siemen Jack 3D Static Strength Prediction Program (3DSSPP) method to get the force on the low back disc. The results of the analysis of the 6 work postures P1 and P2, showed a significant decrease (p <0.05) in the average compression force in the low back disc L4 / L5 on the work posture using modified enggrong. Enggrong modification lowers compression in low back disc L4 / L5 by 38.73% (P1 2143.8 ± 411.3 N; P2 1320.2 ± 418.4 N), anterior / posterior shear 46.17% (P1 542, 6 ± 103.9 N, P2 292.1 ± 81.2 N), and lateral shear 29.69% (P1 31.2 ± 22.08 N; P2 16.6 ± 14.28 N) compared with the use of enggrong standard. The threshold value for compression 3400 N and anterior / posterior shear is 700 N, then the compression and anterior / posterior shear values in Period 2 are well below the threshold. Decrease in the press force in low back disc L4 / L5 is as a result of changes in work posture workers who work using modification enggrong. It can be concluded that the use of modification enggrong can decrease the compressive force in the low back disc L4 / L5 so as to reduce the low back pain occurs to the workers.
