About this study

Official title: PEMFS in Patients With CRPS-I of the Foot and Ankle: a Randomized Controlled Trial

The investigators hypothesize that the association of I-ONE® therapy with standard rehabilitation treatment can optimize the clinical and functional recovery of patients with pulsed electromagnetic fields (PEMFs) (I-ONE® therapy) of the foot or ankle.

Read the detailed description

Study design; spontaneous, prospective, randomized study with control group.

Purpose of the study:

evaluate the functional clinical improvement of the foot/ankle joint with algodystrophic pathology following a standard rehabilitation treatment and home biophysical treatment and local biophysical stimulation with I-ONE® therapy (IGEA SpA).

Being tested
I-One
Keywords

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • I-OneDevice

    Also called I-One, IGEA, Italy

    I-ONE® is a medical device certified by the Ministry of Health as a Medical Device (risk class II A) for the treatment of inflammatory and degenerative tissue pathologies. The device consists of a signal generator and an applicator, called a solenoid. The solenoid will be placed on the joint, not necessarily in direct contact with the skin. The device works with a rechargeable battery and is equipped with an hour counter to assess patient compliance.

    Treatment with I-ONE® therapy will start within 3-7 days of recruitment, will last 6 hours a day and will be maintained for 60 days. The treatment will be carried out at home and the device will be delivered directly to the patient's home by courier.

I-ONE groupExperimentalThe group will undergo home biophysical treatment with I-ONE® therapy (experimental group) for 4 hours/day for 60 days. Patients will follow standard rehabilitation treatment: patients will perform active and active-assisted range of motion (ROM) recovery exercises and stretching exercises for 30 minutes per day, for 6 weeks.

Questions about this trial

What is this clinical trial studying?

A study testing I-One in people with Pain, Joint and Complex Regional Pain Syndromes, run by Azienda Ospedaliero-Universitaria Consorziale Policlinico di Bari at 1 site in Italy.

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 3 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 15 May 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 Italy. 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.

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?

Number of participants with allodynia (time frame: Change from baseline at 3 months). The study lists 15 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 NCT05922618, which also lists 29 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 15 May 2026.
