Postural Stability and Physical Activity of Workers Working at Height

Area of Science:

• Occupational Health
• Biomechanics
• Human Physiology

Background:

• Assessing physical activity and postural stability is crucial for understanding the health and safety of workers in demanding occupations.
• At-height work presents unique physiological challenges that may influence balance and physical capabilities.

Purpose of the Study:

• To compare the levels of physical activity and postural stability between at-height workers and office workers.
• To investigate the relationship between work type, physical activity patterns, and postural control.

Main Methods:

• A comparative study involving 34 healthy men, divided into at-height workers (HW) and office workers (OW) groups (n=17 each).
• Physical activity was assessed using the Baecke questionnaire, evaluating work, sports, and leisure activities.
• Postural stability was measured using the one-leg standing test with eyes open and closed.

Main Results:

• At-height workers reported higher physical activity at work, while office workers engaged in more leisure-time physical activity.
• No significant differences in sports activity were observed between the groups.
• At-height workers demonstrated significantly better postural stability, especially with eyes closed (p < .05).

Conclusions:

• At-height workers possess enhanced postural stability compared to office workers.
• Despite differing activity profiles, overall physical activity levels were comparable, suggesting other factors influence postural control.
• Exposure to distress conditions associated with at-height work may be a key factor in improving postural stability.
