Occupational Footwear Design Influences Biomechanics and Physiology of Human Postural Control and Fall Risk

Abstract

While design modifications present on work boots improve safety, they may not always provide optimal human performance during work tasks. Understanding the impact of these different design features on biomechanical and physiological postural control and locomotion variables can aid in better design modifications that can provide a safe and efficient human performance. This brief review focuses on a series of studies conducted by the current research team, that have tested three different work boots (SB: high-top steel-toed work boots; TB: high-top tactical work boots; SR: low-top slip-resistant work boots). The series of studies included testing of these work boots or combinations of them under acute and chronic simulated occupational workloads, assessing biomechanical variable such as postural stability, gait, slips, and muscle activity, as well as physiological variables such as heart rate, energy expenditure, oxygen consumption, and pain perception. The impact of each of the work boots and their design feature on postural control and locomotion are summarized from these studies’ previously published literature. Finally, work boot design suggestions for optimal human performance are provided for better work boot selection, modification, and design.

Q-angle and postural stability: a review of the relationship and implications for fall risk

“…16 The sensory stimulation information from these systems produces specific circumstances to engage the muscles to resist gravity and to activate the balance system, thus preventing the fall. 17 Another important variable that raises the risk of falling is regarded to be postural stability. 18 The ability of the senses to adapt balance control in order to prevent negative reactions brought on by internal or external disturbances is crucial for maintaining postural stability, which lowers the risk of falls [19][20] .…”

A Cross-Sectional Study Investigating Lumbar Proprioception Impairments in Individuals with Type 2 Diabetes Mellitus: Correlations with Glycated Hemoglobin Levels

“…Falls are a major concern among older adults with diabetes, and impaired proprioception is a known risk factor for falls [55]. By addressing lumbar proprioceptive impairments and improving postural control, healthcare professionals can play a vital role in reducing the risk of falls and fall-related injuries in individuals with T2DM [56,57]. This may involve incorporating proprioceptive training, balance exercises, and education on home safety into diabetes management programs.…”

Special Issue: “Novel Approaches and Applications in Ergonomic Design II”

“…The foot's role as a link to the environment underscores its importance in somatosensory feedback and balance, with potential impacts on stability from improper footwear and occupational regulations. Derby et al [10] presented a review of a series of studies conducted by the authors on the different effects of work boots on postural stability, gait, slips, muscle activity, heart rate, energy expenditure, oxygen consumption, and pain perception. The research assessed biomechanical and physiological variables associated with different types of work boots and their design features to provide recommendations for optimal human performance.…”
