A Clinical Evaluation of Scapular Dyskinesis Among Professional Bus Drivers With Unilateral Upper Quadrant Musculoskeletal Pain

Abstract

Background: Professional bus drivers report a high prevalence of upper quadrant musculoskeletal pain which could be associated with scapular dyskinesis (SD). However, the evidence for valid and reliable screening methods for this condition is limited as SD among bus drivers is an emerging area of research. Therefore, the main aim of the study was to investigate the reliability of dynamic scapular motion test (DSMT) using video analysis as an accurate method to evaluate SD and to identify patterns of SD among bus drivers. Methods: In total, 32 bus drivers from a private bus company with unilateral upper quadrant musculoskeletal pain participated in the study. The DSMT was conducted and the SD was captured in the video during shoulder flexion–abduction movements. Two investigators analyzed the video recordings and identified the patterns of SD. The intra- and interrater reliability were determined using the percentage of agreement and weighted Kappa coefficients (Kw). Descriptive analysis was used to examine the patterns of SD. Findings: The intra- and interrater reliability of DSMT using video analysis were excellent (Kw coefficient: 0.762–0.878 and 0.87–1.00, respectively). About 56.2% and 53.1% of bus drivers presented SD with the shoulder flexion and abduction movements during DSMT. Medial border prominence (Type II pattern of SD) was identified as the common pattern of SD. Conclusion/Application to practice: The DSMT using video analysis showed excellent intra- and interrater reliability to evaluate SD. Occupational health practitioners can consider DSMT using video analysis to identify SD among people with upper quadrant musculoskeletal pain at the workplace.

Methods of engagement and levels of involvement of stakeholders in the management of work-related musculoskeletal disorders: A systematic scoping review

“…The different methods and levels of SE in WRMSD identified in this review might provide information to policy makers, researchers, and organisations in establishing guidelines for engaging stakeholders in WRMSDs care and research agenda. As the SMART Drive network group is currently engaging with various stakeholders as part of developing a comprehensive care and related policies to manage WRMSD in a group of professional drivers (Kasemsan, 2021, Sattasuk, 2021, the findings of the study have direct implications in terms of implementing the methods and levels of SE identified in the current review.…”

Prevalence of Scapular Dyskinesis in Working Dentists: An Epidemiological Study

“…Studies about upper quadrant musculoskeletal disorders in various occupations with ergonomic risk factors, such as prolonged static position and repeated upper limb-based activities for long hours as bus drivers, workers on sewing machines, and mechanics, described the prevalence of upper body pain as being associated with age under 30, female gender, having a diagnosis of an MSD or a systemic illness, working for more than 10 years, higher work-rest ratios, and high physical exertion (54). Additionally, 53% of bus drivers have dyskinesia, which has been linked to unilateral upper quadrant musculoskeletal pain that has been explained by repetitive neck and shoulder motions over an extended period of time and overuse (55,56).…”

An investigation of the prevalence of work-related musculoskeletal pain and related disability among poultry slaughterhouse workers: a cross-sectional study

“…The ethical approval for the study was obtained from a university institutional ethics committee, according to the Declaration of Helsinki (Ethical approval number AMSE-64EX-112). This study was a continuation of the initiatives from the Sustainable Measures for Assessment and Rehabilitation Drive (SMART Drive) research networking group which had been working on a series of projects to enhance and improve musculoskeletal health and wellbeing for people at the work place (Joseph L et al 2020;Joseph L et al 2021;Kasemsan et al 2021;Sattasuk et al 2021).…”
