The physiotherapist will perform a thorough Subjective Assessment to screen for the appropriateness for a Shockwave Therapy. They will document things such as how the injury occurred, what movements aggravate it, previous treatments tried and response, as well as any other medical conditions that you may have, that might mean a cortisone injection isn't appropriate for you.
Note: If your physio has been treating you for the injury already using traditional physiotherapy treatments then they shall have all this information to hand and will discuss/may have discussed with you their thoughts on the use of a Shockwave Therapy.
This subjective will follow with an Objective Assessment which will look at the injury and asses joint range of movement, strength and stability of the structure in question be it a joint, tendon, ligament etc.
The physio will then give you your Report of Findings (ROF) where they will detail what the prognosis of the injury will be and the treatment and management process.
If it has been deemed suitable and you have given your written consent then the intervention will be performed by your physio and acute management post treatment will be discussed.
