At City Osteopathy and Physiotherapy your Osteopath or Physiotherapist may manipulate your back. When an Osteopath/Physiotherapist manipulates your back you may hear a click. The click is due to the surfaces of the joint coming apart creating a potential vacuum. The aim of this is to separate the joint surfaces, which leads to increased movement between the bones that make up the joint, and causes the muscles surrounding the joint to relax. You may feel a little twisted and stretched as the Osteopath/Physiotherapist prepares you for manipulation should not cause pain.
