Final answer:
Overexertion injuries such as musculoskeletal disorders and tendinitis are common among window cleaners due to repetitive movements and awkward postures. Pre-existing conditions can increase the risk and severity of these injuries.
Step-by-step explanation:
Overexertion Injuries in Window Cleaners
Window cleaners working on multi-story office buildings are at risk of several types of overexertion injuries. Two examples of these injuries include:
- Musculoskeletal disorders (MSDs): These are injuries affecting the muscles, nerves, and tendons. For a window cleaner, prolonged repetitive movements such as reaching out to clean windows, lifting heavy equipment, or maintaining stability on a platform can lead to strains and sprains, particularly in the shoulders, arms, and back.
- Tendinitis: This is inflammation or irritation of a tendon. It can result from the repetitive motion of window squeegeeing, especially if done with force or in awkward positions.
The basic causes of overexertion injuries include repetitive motion, forceful exertions, and working in awkward body postures for extended periods. Pre-existing conditions such as previous injuries, arthritis, or muscular imbalances can exacerbate the risk and severity of new overexertion injuries, as they can make the body more susceptible to strain and less capable of recovering from strenuous activity.
