3.1 Introduction
Body mechanics is defined as “the efficient and careful use of the body in moving and lifting.” The goals of body mechanics are to conserve energy and to prevent injury. A thorough knowledge of body mechanics is essential if you are to safely carry out your role as a Health Care Assistant. Body mechanics, however, is not just confined to your working hours. All areas of your life demand a conscious awareness of the need to practice safe body mechanics.
When working as an HCA, you cannot avoid lifting, whether it is assisting a client or lifting a load of laundry. However, you can control how you are lifting. Back, wrist, and shoulder injuries are all too common among health care workers. Many of these injuries could be prevented if workers used correct body mechanics and kept themselves physically fit.
