For the talocrural joint, three lateral collateral ligaments are present and one medial collateral ligament (Bonnel et al., 2010).\n\nPhysical examination is mostly the first diagnostic step in the assessment of ankle injuries. Imaging modalities such as ultrasonography (US) and magnetic resonance imaging (MRI) play a major role in providing a detailed depiction of ankle tendons and ligaments (Hosseinian et al., 2022).\n\nThe effect of ESWT is Higher multiplication of collagen fibers; faster organization of muscle fibers and vascularization by treatment with radial shockwaves (Schnurrer-Luke-Vrbanic et al., 2018), ESWT could improve pain, ankle instability, ankle function, dorsiflexion ROM, and dynamic balance in patients with CAI (Le et al., 2022).\n\nPhotobiomodulation Therapy (PBMT) is effective for patients with an ankle sprain. PBMT showed high effect size with a moderate level of evidence on pain intensity and is related to the PBMT intensity and frequency (Alayat et al., 2024).\n\nHYPOTHESES:\n\nThere is no statistically significant effect of extra corporeal shock wave versus photobiomodulation on level of pain, ROM, muscle strength, function level, dynamic balance and thickness of ligament in patients with chronic ankle instability.\n\nRESEARCH QUESTION:\n\nIs there any effect of extra corporeal shock wave versus Photobiomodulation on pain level, ROM, muscle strength, function level, dynamic balance and thickness of ligament in patients with chronic ankle instability?",[87],"Chronic Ankle Instability, CAI",[89],"extracorporeal shock wave, photobiomodulation, chronic ankle instability","NOT_YET_RECRUITING","2025-08-17",{"date":93,"type":94},"2025-08-24","ACTUAL",{"date":96,"type":81},"2025-08-29",{"date":98,"type":81},"2026-01-10",{"name":5,"class":6},1]
