High Ankle Sprains - Special Tests [External Rotation & Syndesmotic Squeeze Tests]

The video tutorial explains two tests for diagnosing high ankle sprains: the external rotation test and the syndesmotic squeeze test. The external rotation test involves dorsiflexion and external rotation of the ankle, but has limited sensitivity and specificity. The syndesmotic squeeze test involves compressing the fibula and tibia, with a higher specificity. Pain location during the squeeze test can indicate injury severity. Combining both tests improves diagnostic accuracy.

What is the main purpose of the external rotation test in diagnosing ankle injuries?

• To evaluate the strength of the ankle muscles

• To measure the range of motion in the ankle

• To identify potential injury to the syndesmosis

• To assess the flexibility of the ankle joint

Which of the following best describes the sensitivity of the external rotation test?

• Moderate sensitivity, moderate specificity

• Low sensitivity, high specificity

• Low sensitivity, low specificity

• High sensitivity, low specificity

How is the syndesmotic squeeze test performed?

• By stretching the ankle into plantarflexion

• By compressing the fibula and tibia together

• By measuring the ankle's range of motion

• By applying a rotational force to the ankle

What does pain felt higher up the leg during the syndesmotic squeeze test indicate?

• No injury present

• A more severe injury

• A different type of injury

• A less severe injury

What is the specificity of the syndesmotic squeeze test?

• 50%

• 94%

• 63%

• 71%
