Brief Summary
Achilles tendinopathy is a prevalent condition characterized by pain, swelling, and impaired function of the Achilles tendon, commonly affecting athletes and active individuals. The disorder arises from a failed healing response, leading to degenerative changes in the tendon without significant inflammation. It is categorized into insertional (at the calcaneus-Achilles junction) and non-insertional (2-6 cm proximal to the insertion) types. Intrinsic risk factors include biomechanical abnormalities and systemic conditions like diabetes and hypertension, while extrinsic factors involve excessive mechanical load and training errors. Effective management of Achilles tendinopathy is crucial for preventing long-term disability and ensuring the continuation of physical activities.

Outcome Measures
Primary Outcomes (1)
Numeric pain rating scale
The pain NPRS is a unidimensional measure of pain intensity, used to record patients' pain progression, or compare pain severity between patients with similar conditions. Using a ruler, the score is determined by measuring the distance (mm) on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity. It has been shown that NPRS is valid, reliable and interval scale. NPRS has high test-retest reliability of ICC 0.98.

Laser therapy protocol.
ACTIVE COMPARATORThe therapy system will be used the Thor DD Laser Therapy Unit. This will be a class 3B laser with an 810-nm, 100-mW infrared probe. Laser or placebo laser treatment protocols will be identical and will be delivered with the patients lying prone, with their foot over the end of the treatment plinth and the ankle plantar-grade. The contact method will be used to apply the laser treatment probe to 3 standardized points on both sides of the Achilles' tendon (6 in all: at the site of the lesion, 2cm proximal, and 2cm distal) for 30 seconds, giving a dose of 3J per point and 18J per session for the active probe. .
Extracorporeal shock wave therapy protocol.
ACTIVE COMPARATORWhen treating Achilles tendinopathy, most researchers will be used 3 sessions of extracorporeal shock wave therapy (ESWT) with a one-week break in between. There will also be shorter breaks of 3 to 4 days or longer 2-week breaks. The number of pulses per session will range from 800 to 3000, and the pulse frequency will be between 4 and 50 Hz.

The treating physiotherapist, without any knowledge of which position on the switch will be the active laser, will select position 1 or 2 on the switch according to group allocation.
