Physical therapy relates to those treatment modalities that address the musculo-skeletal frame. When treating a physical body for injury, pain or malfunction, Interferential therapy may be first applied to reduce pain, increase circulation, and treat muscle spasm or inflammation before Massage is manually applied to the physical body. This greatly enhances the therapeutic effect on an injury or musculo-skeletal derangment. It is recommended that these therapies precede any manual adjusting of the spine or limbs with Chiropractic or Osteopathic techniques as it improves the treatment outcome.
