Ankle sprains are commonly classified into three grades or levels based on the severity of the injury. These grades provide a general framework for understanding ankle sprains, but individual cases may vary.
The three grades of ankle sprains are:
Grade 1 (Mild)
Ligament Damage: Slight stretching or microscopic tearing of the ligament fibers.
Symptoms: Mild pain, minimal swelling, and little to no joint instability.
Range of Motion: Generally, the range of motion is maintained, and the employee can often bear weight on the affected ankle.
Grade 2 (Moderate)
Ligament Damage: Partial tearing of the ligament.
Symptoms: Moderate pain, noticeable swelling, and some joint instability.
Range of Motion: Reduced range of motion and walking may be challenging for the worker.
Grade 3 (Severe)
Ligament Damage: Complete tearing of the ligament or ligaments.
Symptoms: Severe pain, significant swelling, and pronounced joint instability.
Range of Motion: Limited to no range of motion, and weight-bearing is often very painful or impossible for the worker.
