Ankle Orthopaedic Test: Peroneus longus and brevis tests
May 24, 2023Peroneus longus and brevis are two muscles located in the lower leg that help to stabilize and move the ankle joint. There are a few tests that can be done to evaluate the strength and function of these muscles. Here are the steps for each test:
Position the patient lying on their side with the affected leg on top.
- Hold the patient's foot and ankle in a neutral position (not inverted or everted).
- Ask the patient to actively evert their foot against resistance.
- Resist the movement by applying pressure against the lateral aspect of the foot.
- Observe the strength and quality of the movement.
In both tests, it is important to observe for any pain, weakness, or abnormal movement patterns. These tests can help to diagnose conditions such as ankle sprains, peroneal tendonitis, or ankle instability.
