From August 15, 2012. What causes low back pain? What positions are the absolute worst for the lower back region? What is “the core” and why is it so important? Is the core truly a “powerhouse” of strength? Can the core be “trained” to create postural correction? Why is sciatica (nerve root irritation) so common in people and how can it be prevented? Do you feel pain that travels down the back and outside of the leg to the toes? If so, you may be suffering from sciatica. On this show, our guest, Karena Wu, a graduate of Columbia University’s Program in Physical Therapy, a NYS licensed manual Physical Therapist and owner of ActiveCare Physical Therapy, explains these questions and more. Karena also breaks down some of the common myths that many people believe about Physical Therapy. Listen now.
