Correct positions for bending
When standing with your back straight the stresses on intervertebral discs and ligaments in the back are considerably lower than when you stand with your back bent forward. Many every-day-activities may cause spinal bending – for example gardening, vacuuming, occupations requiring, etc. While working in these bent positions, you are more likely to sustain back problems in the first four or five hours of the day.
In order to minimize the risks involved in prolonged forward bending you should interrupt the stooped position at regular intervals before pain starts.
When working in a stooped position, regular interruption of the bent posture is essential to prevent the onset of pain. This can be achieved by standing upright and bending backwards five or six times.
