Analysis of Hyperthermia as an Adjunctive Treatment to Evidence-based Clinical Intervention in Subjects With Plantar Fasciitis: a Double-blind Randomized Clinical Trial

Hyperthermia will be applied for a period of 15 to 20 minutes in the area to be treated, maintaining a thermal sensation of gentle heat for the patient and accompanied by active-assisted or passive mobilization of the structures adjacent to the plantar fascia.

The therapeutic physical exercise focused on the flexor muscles of the foot will consist of 3 periods of isometric contraction of 15 seconds, with a rest period of 30 seconds, varying the number of repetitions from 3 to 5 depending on the patient's symptoms.

The plantar fascia stretch will be performed with the patient in the supine position. Maximum dorsiflexion will be achieved, and the lower limb will be elevated with the knee extended as tolerated. This procedure will be performed three times in a row for 30 seconds, with a 1-minute rest between each stretch.
