Achilles Tendinopathy
Conditions
Brief summary
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
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.
Interventions
Participants will receive shockwave therapy once a week for three weeks
Participants will receive photobiomodulation therapy twice a week for three weeks
Participants will enroll in physical therapy and complete an at-home exercise protocol

Recruitment details
Target enrollment was 60 participants randomly assigned equally to three groups. No power calculations were used to determine sample size as no comparable studies were identified to estimate effects of RPW. Eligible participants were runners aged 18-65 with primary running-related injury diagnosed as unilateral or bilateral non-insertional AT and symptoms exceeding 3 months. Each reported running as their primary sport, with weekly volume \>16 km.
Pre-assignment details
After screening and obtaining written informed consent, participants who enrolled were assigned, using block randomisation design, o one of three conditions: EXER; EXER and RPW; or EXER, RPW and PBMT. After 3 months, participants could elect to participate for three additional months using a different treatment than initially prescribed (EXER +RPW or EXER + RPW + PBMT) or could continue EXER and complete a 6-month follow-up visit.
