Purpose

The purpose of these tests is to locate the peronei musceles.

Technique

Peroneus brevis:

Patient position:
Semi-lateral position on the contralateral side with the ankle in neutral position.

Instructions therapist and patient:
Immobilize the distal calf with one hand proximal to the ankle while pressing to the lateral margin of the foot into eversion with the other hand. Instruct the patient to evert the foot and the talocalcaneoavicular joint in a neutral position. Make sure that the long extensors are relaxed and the toes are held in slight flexion. [1][2]


Peroneus longus:

Patient position:
Semi-lateral position on the contralateral side with the ankle in plantar flexion.

Instructions therapist and patient:
Immobilize the distal calf proximal to the ankle with one hand. At the same time, press with the other hand against the head of the first metatarsal to elevate it, invert the foot, and move the ankle into dorsiflexion. Instruct the patient to evert the foot and bring the head of the first metatarsal into plantar flexion. Make sure that the toe extensors are relaxed for this maneuver. [1][2]
