It is not always possible to prevent sciatica from occurring. However, patients can take several steps to help reduce the risk of experiencing pain related to sciatica. These include:
Regular exercise. Exercise programs can strengthen muscles, particularly in the lower back and abdomen, that can help protect the body against sciatica.
Proper posture when sitting. Sit in a chair that comfortably supports the hips and that does not press into the back of the thighs or knees. Place a rolled towel or pillow behind the back to help support the natural curve of the lower spine. Adjust the seat so feet are flat on the floor, and use chairs with armrests. When driving, adjust the seat so knees and hips are level. Move the seat to avoid having to overreach for pedals.
Proper body mechanics. Stand with good posture, lift heavy objects by bending at the knees rather than the back and sleep on a firm mattress and pillows that do not force the neck up at a steep angle.
Regular medical care, good diet and routine safety measures. Prevention or treatment of underlying conditions such as peripheral arterial disease, osteoporosis, spinal stenosis or scoliosis may help avert sciatica. Practicing safety steps such as defensive driving and proper use of seat belts and ladders may help prevent potential causes of sciatica such as acute pelvic fractures.
