Many with Left side tighter than right?

Generally, from a therapy point of view, you (or your clients) can have an imbalance of one o more of this structural complex system:

  1. Cranio-cervico-mandibular system
  2. Pelvic system
  3. Feet/gait complex

A chiro can help you to identify the cause of your problem.

Spinal manipulation can be a waste of time if you work only on this structure (too much adaptative).
