Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a randomized control trial with an elective cross over after three months to evaluate three different treatments in the management of non-insertional Achilles Tendinopathy. The treatment methods include physical therapy, shockwave therapy and photobiomodulation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a randomized control study with an elective cross over. In part 1 of the study participants will be randomized into one of three treatment arms: 1) physical therapy only; 2) physical therapy and shockwave therapy; 3) physical therapy, shockwave therapy and photobiomodulation. At 3 months, patients can choose to switch to a different treatment arm than they were initially randomized.
