When we say “physical therapy,” most people imagine things like stretching exercises, heat, or massage. While those impressions aren’t wrong—all can be effective components of a physical therapy treatment course—the full definition is much broader and more inclusive.
Physical therapy also includes things like electrical stimulation, ultrasound or Radial shockwave therapy, etc. Essentially, physical therapy uses external, mechanical forces to bring about increased blood flow to accelerate healing, rather than surgery or drugs. And it can be used not only as part of rehabilitation, but as a primary treatment for many conditions.
