The most common cause of sciatica is a herniated disk. Disks act like cushions between the vertebrae of your spine. These disks get weaker as you age and become more vulnerable to injury. Sometimes the gel-like center of a disk pushes through its outer lining and presses on the roots of the sciatic nerve. About 1 in 50 people will get a herniated disk at some point in life. Up to a quarter of them will have symptoms that last more than 6 weeks.
Approximately 15 degrees of hip extension is required to walk normally. If hip flexors are tight then in order to walk, compensatory movement needs to take place through the lower back causing back pain and premature disc degeneration. Like other joints, if we fail to take them through their full range on a regular basis we eventually lose mobility.
The sacroiliac joint typically has little motion. Small movements at the joint help with shock absorption and forward/backward bending. The joint is reinforced by strong ligaments surrounding it, some of which extend across the joint in the back of the pelvis. This network of soft tissues provides support, limits movement at the joint, and assists with absorbing pressure.
If your sciatica is due to a herniated disk, and it's still causing severe pain after four to six weeks, surgery may be an option. The surgeon will remove a portion of the herniated disk to relieve the pressure on the sciatic nerve. About 90% of patients get relief from this type of surgery. Other surgical procedures can relieve sciatica caused by spinal stenosis.
The hip flexor stretch has become a very popular stretch in the fitness and sports performance world, and rightly so considering how many people live their lives in anterior pelvic tilt. However, this seems to be one of those stretches that I see a lot of people either performing incorrectly or too aggressively. I talked about this in a recent Inner Circle webinar on 5 common stretches we probably shouldn’t be using, but I wanted to expand on the hip flexor stretch as I feel this is pretty important.
Kneel on your mat with thighs perpendicular to the floor and tops of of your feet facing down. Place a yoga block between your feet. Bring your inner knees together. Slide your feet apart so they are slightly wider than your hips, and press the tops of your feet evenly into the mat. Slowly sit down on the yoga block. Use your hands to turn the top of your thighs inward. Allow the backs of your hands to rest on your thighs. Hold for at least 30 seconds.
Hip hikers (also known as the pelvic drop) are great exercises to get your gluteal muscles working in a weight bearing position. To do the exercise, stand sideways with one foot on a step and the other hanging off. Keeping both knees straight, lower down your pelvis on one side so your foot moves toward the floor. Both knees should remain straight; the motion should come from your hip joint. Once your pelvis is lowered down, slowly raise it back up to the starting position. Repeat the exercise for 10 repetitions.
The hip flexors are the muscles at the front of your hip. They’re responsible for several essential functions. Since they’re so often overlooked, we often forget to stretch them before exercising or engaging in rigorous activities. Tight hip flexors can also be a product of being sedentary. So, if you don’t lead an active lifestyle, or if you spend most of your day sitting at a desk, you’ll be susceptible to hip flexor tightness.
Mobility and exercise (e.g., walking, running, stretching, etc.) help to more evenly distribute the forces of impact and weight through this ball-and-socket joint. As people age or find themselves living a more sedentary lifestyle from (e.g., sitting a lot at work), the wear and tear of the hip joint is less distributed, taking place in a smaller area within the socket.
