About this study
Official title: Percutaneous Femoral Nerve Neuromodulation for Postoperative Analgesia and Functional Recovery Following Knee Arthroplasty.
The goal of this clinical trial is to compare the maximum isometric contraction force differential of the quadriceps in the postoperative period after the use of a peripheral nerve neuromodulation program in patients undergoing knee arthroplasty. The main questions it aims to answer are if the combination of a peripheral neuromodulation program in the perioperative period improves analgesic quality and short-term functional recovery in patients undergoing knee arthroplasty,
Participants will be asked to reach a maximum knee extension prior to neurostimulation Patients will have the electrodes inserted under direct ultrasound vision and placed near the femoral nerve.
Researchers will compare whether there is a difference in both quadriceps contraction force and analgesia between the stimulated group and the control group.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Percutaneous neuromodulation using the EPTE® Bipolar System deviceDevice
The two stimulation protocols will be applied consecutively. Firstly, the high-frequency protocol (HFS) will be applied in order to produce potentiation of the non-nociceptive pathway, using the pulsed square waveform and 5 bursts of stimulation lasting 5 seconds at a frequency of 100 Hz separated by 55 s interval between bursts. Adjustments to amplitude and pulse width are made until the patient experiences paresthesias at a perceptible but not painful intensity, and the intensity will be set 200 μA above the detection threshold for each subject.
In order to depress the nociceptive pathway, the low-frequency protocol (LFS) with stimulation at 2 Hz for 16 min with an intensity of 1000μA will subsequently be switched to. To ensure the recruitment of higher threshold type C nociceptive fibers, the intensity level will be programmed at the pain threshold for each subject.
| Study group | Role | What they receive |
|---|---|---|
| Neuromodulation group | Experimental | The maximum isometric contraction force of the quadriceps will be measured prior to the neuromodulation program using a hand dynamometer.
The percutaneous neuromodulation program will begin using the EPTE® Bipolar System device. The two stimulation protocols will be applied consecutively. Firstly, the high-frequency protocol (HFS) will be applied using the pulsed square waveform and 5 bursts of stimulation lasting 5 seconds at a frequency of 100 Hz separated by 55 s interval between bursts.
The low-frequency protocol (LFS) with stimulation at 2 Hz for 16 min with an intensity of 1000μA will subsequently be switched to.
The surgical intervention will be carried out by subarachnoid block with local anesthetic in accordance with the usual practice.
After its completion, a single injection block of the femoral nerve will be performed with a long-acting local anesthetic , a regional anesthesia technique included in routine clinical practice. Receives: Device: Percutaneous neuromodulation using the EPTE® Bipolar System device |
| Control group | No intervention | The neuromodulation program will not be carried out. Only the maximum contraction force of the quadriceps prior to subarachnoid block will be measured. After the intervention, the femoral nerve block will be performed following the usual clinical practice. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Quadriceps maximal isometric contraction force differential after the use of a peripheral nerve neuromodulation program with direct current at low frequency combined with high frequency
To compare (analyze) the differential of the maximum isometric contraction force of the quadriceps in the postoperative period after the use of a peripheral nerve neuromodulation program with direct current at low frequency combined with high frequency compared to the usual practice.
Measured: Before neuromodulation, immediately after the first phase of the program, and 24 hours after it.
Secondary outcomes (1)
VAS score and Opioid use
To compare the analgesic efficacy with the use of the described neuromodulation program versus the usual practice, in which it is not performed, in patients undergoing knee arthroplasty.
Measured: In the immediate postoperative period in the PACU and at 24 hours

Questions about this trial
What is this clinical trial studying?
A study testing Percutaneous neuromodulation using the EPTE® Bipolar System device in people with Acute Pain, run by Hospital General Universitario de Valencia at 1 site in Spain.
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 4 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 2 Aug 2023. 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 Spain. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact FERRAN MARQUES PEIRO, MD (34671364792, fermarpei@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Quadriceps maximal isometric contraction force differential after the use of a peripheral nerve neuromodulation program with direct current at low frequency combined with high frequency (time frame: Before neuromodulation, immediately after the first phase of the program, and 24 hours after it.). 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 NCT05971095, which also lists 14 linked publications.
Does a listing mean the treatment is approved or proven to work?
