Comment

According to the follow-up survey, the discomfort that he had before the changes has been eliminated. The keyboard tray was a major contribution to his improved work posture that led him to feel comfortable. The phone position does still pose a problem. Since the current telephone cords hinder getting in and out of drawers, the phone is placed too far away from the subject to be at a comfortable reach distance. Our recommendation is to use an extended cord that goes around the back of the desk, thus moving the phone closer.
