# Insights into effective rest breaks for reducing cognitive and musculoskeletal strain in farm machinery operators: a qualitative reflexive analysis

## TL;DR

Farm machinery operators prefer active rest breaks like walking or stretching to reduce physical and mental strain caused by whole-body vibration, but face barriers like time constraints and work habits.

## Contribution

This study identifies contextual and behavioral factors influencing the adoption of movement-based rest breaks among farm machinery operators.

## Key findings

- Farm operators prefer active breaks (e.g., walking, stretching) over passive ones for physical and mental relief.
- Time-sensitive agricultural tasks and ingrained work habits hinder regular break-taking.
- Flexible, task-compatible movement strategies are more acceptable than rigidly scheduled breaks.

## Abstract

Agricultural machinery operators are frequently exposed to whole-body vibration (WBV), which contributes to musculoskeletal discomfort, cognitive fatigue, and impaired balance. While engineering controls such as improved seating and suspension systems have been widely studied, there is growing interest in complementary behavioral interventions, such as regular movement-based rest breaks, to mitigate the negative health effects of WBV exposure.

We explored operators’ perceptions of rest break activities aimed at reducing WBV-related strain, with attention to factors influencing uptake, acceptability, and real-world feasibility.

This was a reflexive-descriptive qualitative piece, to a broader experimental study involving 15 participants (10 in-lab, 5 in-field). In-lab participants completed a WBV simulation protocol and evaluated structured break activities (sitting, walking, stretching); in-field participants were observed on machinery and interviewed about their usual practices. Thematic analysis was conducted using an inductive approach.

Five overarching themes emerged. Participants preferred movement-based breaks but noted barriers such as time constraints and ingrained work habits posed significant barriers to regular break-taking. Greater awareness of WBV’s long-term health impacts was considered as motivators. Perceptions of WBV exposure differed between lab and field participants, influencing the perceived urgency for rest breaks. While engineering controls (e.g. seat design) were valued, they were viewed as necessary but insufficient without complementary active self-care strategies.

Movement-based breaks were perceived as beneficial, but their adoption requires flexible, context-sensitive integration into daily routines. Interventions like gaze stabilization exercises offer physiological benefit, but must be adapted to respect farmers’ work routines and productivity imperatives for successful uptake.

Farm machinery operators favor active breaks (e.g., walking, stretching) over passive ones (e.g., sitting), citing benefits for both physical relief and mental clarity.Despite recognizing the benefits of taking occasional breaks between vibration exposure, deeply ingrained work habits and time-sensitive agricultural demands (e.g., during harvest) pose significant barriers to regular break-taking.Farm machinery operators are more receptive to ‘incidental’ or ‘dual-purpose’ movement (e.g., walking while inspecting equipment) than to rigidly scheduled breaks. Flexible and task-compatible strategies are preferred.For uptake in agricultural settings, break interventions should respect the local contexts and realities of seasonal work intensity, cultural norms, and workflow interruptions.
