Short answerPain and tenderness in the lateral collateral ligaments can last for weeks following an ankle sprain. Direct 980/1470 nm clinical evidence for laser is limited. 980 nm may help with symptom control in superficial ligament and periarticular soft tissue; balance, proprioception, and progressive loading form the foundation of treatment.
Why does pain persist after a sprain?
ATFL/CFL ligament injury, joint stiffness, muscle weakness, or chronic instability can lead to residual pain.
980 and 1470 nm
980 nm is more rational for superficial-to-mid-depth ligament and soft tissue targets. 1470 nm has a superficial thermal character and may be considered in selected, very superficial tender areas; direct evidence is lacking.
Scientific evidence
Level of evidence: C+. Although the orthopedic pain and soft tissue PBM literature is supportive, strong HILT data specific to chronic ankle sprains is scarce.
Our approach at our Bodrum clinic
The possibility of instability, fracture sequelae, peroneal tendon pathology, and osteochondral lesions is evaluated. If laser is available, it is added to the balance and strength program.
