Lumbar Stretches and Exercises for Low Back Pain and Sciatica from your San Francisco Chiropractor. Stretching should be an integral part of your low back pain and hip treatment as back muscles and hip muscles will spasm and contract when injured. In order to regain full function of the lumbar spine and the hip joint full range of motion must be re-established. These lumbar and hip stretches are best done on the floor on a towel, mat, or some sort of padding to protect the knees. Watch as Dr. Andrea Schillingh of Executive Express Chiropractic in downtown San Francisco demonstrates the lumbar and hip stretching routine we recommend for our low back pain and sciatica patients at the mid point of their treatment program. If you have any questions you can call and ask to speak with one of our San Francisco Chiropractors at 415-392-2225. We have been serving the SF Financial District since 1992.
