Technique Update: Chiropractic Adjustments Improve Lower Limb Strength

by Dr. David Graber, Council on Technique & Clinical Excellence Chair

Can Chiropractic adjustments improve athletic performance? A recent study suggests that they can.  Published in the European Journal of Applied Physiology, a single session of spinal manipulation increased muscle strength and corticospinal excitability to ankle plantar flexor (Soleus) muscles in elite Taekwondo athletes. The increased maximum voluntary contraction force lasted for 30 minutes, and the corticospinal excitability increase persisted for at least 60 minutes.

The spinal manipulations were performed by a licensed chiropractor who assessed the function of the entire spine and both sacroiliac joints for segmental dysfunction and performed spinal manipulation where he found it was indicated. The clinical indicators for segmental dysfunction include joint tenderness, restricted intersegmental range of motion, asymmetric intervertebral muscle tension, and abnormal or blocked joint play and end-feel of a joint.
