12 Ergonomic Adjustments That Reduce Injury Risk at Work

8. Telephone and Communication Device Ergonomics - Preventing Neck and Shoulder Problems

Proper positioning and use of telephones and communication devices are critical ergonomic considerations that can prevent significant neck and shoulder injuries, particularly for workers who spend substantial time on phone calls while performing other tasks. Research from the National Institute for Occupational Safety and Health shows that cradling a phone between the ear and shoulder can increase neck muscle tension by over 200%, leading to cervical spine disorders and tension headaches. The most effective solution for frequent phone users is a hands-free headset that allows for natural head positioning while keeping the hands free for other tasks. Studies published in the Journal of Occupational Medicine demonstrate that headset use reduces neck and shoulder pain by up to 70% compared to traditional handset use among customer service representatives and other phone-intensive workers. When headsets are not available, the phone should be positioned within easy reach on the same side as the dominant hand to minimize reaching across the body, and users should alternate ears when possible to prevent asymmetrical strain. For workers using mobile devices, the screen should be held at eye level to prevent forward head posture, and voice-to-text features should be utilized when possible to reduce repetitive thumb and finger motions. Additionally, speakerphone functionality should be used when appropriate and feasible, as this completely eliminates the need for holding devices and allows for more natural posturing during conversations.
