About this study

Official title: Clinical Effects of the Intralesional Application of Incobotulinum Toxin vs Corticosteroid in Patients With 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Visual Analogue Pain Scale

    zero is equivalent to no pain and 10 indicates the worst possible pain

    Measured: Initially, 4, 8 and 16 weeks.

  2. Clinical Functional Status of the Ankle and Foot

    Result of the total summative score of the American Foot and Ankle Society Scale, Excellent=90-100, Good =80-89, Medium=70-79, Poor=<70.

    Measured: Initially, 4, 8 and 16 weeks.

  3. Index of Functional Disability of the Foot and Ankle in Activities of Daily Living

    Result of the total summative score of the Ankle disability index scale. Absence of disability or pain = 100 Mild=80-99 Moderate=50-79 Severe:1-49 Maximum disability level = 0

    Measured: Initially, 4, 8 and 16 weeks.

  4. Index of Functional Disability of the Foot and Ankle in Sports Activities

    Result of the total summative score of the ankle disability index scale. Absence of disability or pain = 100 Mild=80-99 Moderate=50-79 Severe:1-49 Maximum disability level = 0

    Measured: Initially, 4, 8 and 16 weeks.

Secondary outcomes (1)
  1. Mobility Arc

    Range of motion (degree of travel) or total angular/axial displacement allowed at ankle joint, dosiflexion degrees at the time of data collection, will be expressed in the results by mobility range groups according to the American Academy of Orthopedic Surgeons AAOS.

    Measured: Initially and 16 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Incobotulinum Toxin A and Glucocorticoid in people with Plantar Fasciitis of Both Feet and Pain, run by Instituto Mexicano del Seguro Social at 1 site in Mexico.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Mexico. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Visual Analogue Pain Scale (time frame: Initially, 4, 8 and 16 weeks.). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06788158, which also lists 20 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Nov 2026.
