9. PHYSICAL LOAD 26 9.3. Proper posture is the basis for ergonomic load Ergonomic spine and joints load is possible when the body’s central lines are in place. In this case, the spine viewed from the front or back appears to be straight. The spine viewed from the side is ”straight”, i.e. vertebrae along with discs are in the proper position. The spine in your neck (cervical spine) has a slight inward curve, the upperto mid back (thoracic spine) curves outward slightly; the lower back (lumbar spine) has a slight inward curve. The head is in the natural central position and the neck and shoulders are relaxed Maintain ergonomic standing posture engaging the lower extremities and abdomen muscles. Try to keep your weight evenly distributed over both of your feet and knees in central position. If, due to work task, you have to keep your weight more on one foot, try to shift sides. ! To prevent discomfort, avoid standing with putting pressure on joints for too long, so called ”hip-rest,” or keeping knees inward. Remember, good posture means that the upper back is relaxed and slightly outward, it is not stiff and not pushing the chest forward. © Valmius Hyvinvointiin Group Oy
