Effect of Microbreaks on Perceived Discomfort of Veterinary Workers Performing Abdominal Ultrasonography

Musculoskeletal symptoms related to work activities are reported by 65-91% sonographers imaging human patients, yet little is known about risks in veterinary ultrasonography. A 2024 study identified a significant risk of musculoskeletal injury to veterinary ultrasonographers performing abdominal ultrasounds. To address this concern, a microbreak training intervention was implemented in 2025. The current study investigated the effect of short, intentional breaks, termed microbreaks, on the perceived discomfort of veterinary workers performing abdominal ultrasounds. Sixty-five videos of a convenience sample of veterinary sonographers were analyzed using Inseer, an AI-powered ergonomics software. Microbreak intervention was randomized by pair of procedures. Qualitative interviews were conducted to explore the workers’ experiences with microbreaks. Consistent with the 2024 study, an elevated risk of musculoskeletal injury was identified in all ultrasound sessions. Of note, the liver and right adrenal gland were the most high-risk organs to scan. Our findings suggest that veterinary sonographers incur a risk of musculoskeletal injury related to their work. Furthermore, a microbreak intervention, when employed in the proper context, provides subjective benefits in reducing discomfort without interrupting workflow.
