Comparison of Photobiomodulation and Anti-Inflammatory Drugs on Tissue Repair on Collagenase-Induced Achilles Tendon Inflammation in Rats.
RatOtherWistarFemalen = 205 female Wistar rats in total, n = 5 per group at each ti…Transcutaneous laser irradiation of the Achilles tendon3 J, 100 mW, 810 nm
Model: Peritendinous collagenase injection (100 micrograms per tendon) induced Achilles tendinitis
Low-level laser therapy prevented haemorrhage, reduced inflammation severity and preserved tendon morphology, showing significant superiority over diclofenac and dexamethasone, both of which prolonged the inflammatory phase and slowed normalisation of tendon quality, particularly dexamethasone.
