Have you heard the rumors that running or squatting is bad for your knees? Do you have Achilles Tendonitis, Plantar Fasciitis, Shin Splints, Knee or Hip Pain? Has your rehab or Physical Therapy only focused on the area of pain and not how your entire body is reacting to the ground?
Try this simple test, an inline kneel. Line up your front foot, directly "inline" with your back knee, your back foot should be down. Try to hold this for 30 seconds. Can you hold it? Are you wobbling all over? If you are not steady in the position, you are running on that instability! Runners legs afford them so much stability, your legs may be overcompensating for a lack of stability or strength in your hips, lumbar or thoracic spine. Your issue may be the opposite a lack of stability in your hips, in concert with your lumbar spine. You may lack mobility in your thoracic spine. Tightness in your shoulders can affect your lumbar spine through your latissimus dorsi! The fascia from your lats crosses the same and the opposite side posterior hips.
Practice this position until you get steady in it, then add challenges such as chops and lifts with a ball or a small weight.
A movement screen (FMS, SFMA) can be very effective way to discern where the issue is occurring. Call 720-352-0678 for a free phone consult, or schedule online at http://www.neuromuscularstrategies.com
