• Conditions: First Ray Dorsiflexion

• Registration Number: NCT05647616

SUBJECTS: Patients with flexible dorsiflexed first ray. INTERVENTIONS: Patients will be randomly assigned to either group A, which will receive instructions for a strengthening programme of the peroneus longus muscle, or group B, which will receive no treatment.
