Plantar fasciitis is inflammation of plantar fascia.The main symptom of plantar fasciitis manifests itself as localized pain in the inner area of the foot and increases in intensity after long periods of standing or resting. Its etiology is multifactorial and risk factors include overweight, female gender, physical exercise (impact sports), biomechanical imbalances of the foot and possible dysfunction of the functional twin-ankle-plantar system.Generally speaking, conservative measures are recommended as initial treatment for plantar fasciitis, and in situations where these are ineffective, corticosteroids are sometimes administered. At the local level, the route of administration can be by infiltration or iontophoresis.Iontophoresis consists of administering a drug through the skin by applying an electric current locally. This technique can be considered as a safe and effective method within the SLTF (Transcutaneous Drug Delivery Systems). It consists of introducing ions through the skin by means of electricity using a direct current, with an electrode carrying a positive charge (anode) and a negative charge (cathode). Its administration is produced thanks to the repulsive force to carry the compound through the skin by means of galvanic current.

This study aims to assess whether treatment with iontophoresis in subjects with plantar fasciitis can show a more positive evolution in pain after a 6-week treatment period (treatment frequency: 1 time per week) versus ultrasound (3 times per week) for 6 weeks.
