Effect of High-intensity Laser Therapy on Shear-wave Elastography Parameters in Achilles Tendinopathy: A Case Report

Achilles tendinopathy is a common musculoskeletal occurrence primarily affecting athletes, but the general population is also prone to develop this pathology. Shear-wave elastography serves as a complement to traditional ultrasound imaging in assessing tendon properties in patients with Achilles tendinopathy. High Intensity Laser therapy (HILT) is a non-invasive and painless treatment option, exhibiting anti-inflammatory, analgesic, and bio-stimulant characteristics. However, limited evidence exists on the effectiveness of high-intensity laser therapy on shear-wave elastography parameters in patients with Achilles tendinopathy. This case study examines the case of a 22-year-old male with a complaint of pain in the Achilles region. He reported stiffness in the morning and difficulty with weight-bearing activities. To assess patient numeric pain rating scale, range of motion (using goniometer) and shear-wave elastography were used. High-intensity laser therapy was administered to the patient for three sessions alternately. Outcome measures were assessed at baseline and after the commencement of treatment. HILT demonstrated positive effects in reducing pain and improving tissue elasticity in patients with Achilles tendinopathy, as observed through shearwave elastography. These results indicate that HILT may serve as a valuable complement in the conservative treatment of Achilles tendinopathy
