Dynamic stabilization refers to exercises that target your core posture muscles by keeping your trunk steady while you move one or more of your extremities. (It doesn't matter which direction you move your arms or legs.)
For people with weak trunk stabilizer muscles -- the abdominal and back muscles especially -- arm and/or leg movement may cause a corresponding movement of the trunk. This type of responsive trunk movement often means there's weakness in the core. Weakness in core posture muscles may cause or increase joint stress and/or back pain. Dynamic stabilization exercises may help strengthen the core, which in turn may help relieve or manage your back pain.
Dynamic stabilization exercises are used in physical therapy clinics for people with upper and lower back pain. They are also taught in yoga, Pilates, and other core-strengthening programs.
