Clinical Effects of Incobotulinum Toxin vs Corticosteroid in Plantar Fascitis

Objectives: To evaluate the clinical effects of intralesional application of incobotulinum toxin vs corticosteroid in patients with plantar fasciitis . Material and methods: Prospective, experimental, randomized, controlled clinical study; the population will be recruited in the outpatient clinic of the rehabilitation service meeting the inclusion criteria, two randomized study groups will be formed: GROUP A: Patients who accept intralesional infiltration with incobotulinum toxin . GROUP B: Patients who accept intralesional infiltration with dexamethasone. Both groups will be assessed before application, at 1 month, at 2 and 4 months post intervention. The visual analogue scale (VAS), the American Orthopaedic Foot and Ankle Society (AOFAS) scale and the Foot and Ankle Disability Index (FADI) will be used to assess pain, foot functionality, functional disability index in activities of daily living, in physical activity and measurement of the dorsiflexion arch in 2 visits at the beginning of diagnosis and at 4 months, collecting the variables and establishing a hypothesis analysis to accept or discard normality criteria of the same with tendency and its significance in relation to p \<0.05 to establish contrast of the results with parametric or non-parametric variables according to whether or not the hypothesis of normality is discarded.
