Study of Patients With Knee Prostheses Treated With Noninvasive Neuromodulation

March 24, 2024 updated by: Aníbal Báez Suárez, University of Las Palmas de Gran Canaria

Study of Patients With Knee Prostheses Treated With Noninvasive Neuromodulation. PRONES Trial

It will consist of a randomized clinical trial with a control group. The sample will be distributed as homogeneously as possible into two groups, which will be randomly divided into a control group, to which the usual general treatment will be applied, and an experimental group, which will be treated with the NESA XSignal device. During the procedure, the subjects will continue to receive the usual care routine.

Study Overview

Detailed Description

The main objective will be to evaluate the efficacy of the NESA XSignal device in relation to the improvement of pain, functionality and quality of life in patients who have undergone total knee replacement surgery.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Crossover Assignment
  • Masking: Quadruple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Non-invasive Neuromodulation
Non-invasive Neuromodulation Intervention with microcurrents: application of 6 electrodes per extremity and an adhesive electrode at C7 level.

The electrodes will be placed with the help of gloves and adapted socks for 1 hour, twice a week, until 10 intervention sessions are completed. In addition, depending on the session, an adhesive electrode will be placed at the level of C7.

Characteristics of microcurrents: pulsed monophasic rectangular wave with a pulse of 1.3 s and pause of 300 ms, voltage 3 millivolt and intensity 0.5 μA.

Placebo Comparator: Placebo Non-invasive Neuromodulation
Intervention with microcurrents: application of 6 electrodes per extremity and an adhesive electrode at C7.
The same protocol described for the experimental group will be applied, but microcurrents device which will be previously manipulated and tested with an oscilloscope so that they do not emit electrical currents.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Pain assessed by VAS
Time Frame: Baseline and up to four weeks

The instrument will be used to measure the change of pain before and after the intervention will be the Visual Analogue Scale (VAS).

Participants will be asked to mark the level of their pain on a 100 mm, no hatched VAS scale marked at one end as "no pain" and at the other as "worst pain imaginable".

Baseline and up to four weeks
Change in WOMAC questionnaire
Time Frame: Baseline and up to four weeks

The WOMAC ( Western Ontario and McMaster Universities Osteoarthritis Index) questionnaire measures quality of life, in terms of Symptomatology and Physical Disability, in people with osteoarthrosis of the hip or knee.

It contains 24 items grouped into 3 scales: pain (0-20), stiffness (0-8), functional capacity (0-68).

The scales are used separately, they are not added together.

Each item is answered with a 5-level verbal-type scale that is coded:

None = 0; Little = 1; Quite a lot = 2; A lot = 3; Very much = 4.

Baseline and up to four weeks
Change in the quality of life test
Time Frame: Baseline and up to four weeks

The EuroQol questionnaire will be used: a generic instrument for measuring health-related quality of life that can be used both in relatively healthy individuals (general population) and in groups of patients with different pathologies. The individual him/herself assesses his/her state of health, first in levels of severity by dimensions.

The descriptive system contains five health dimensions (mobility, self-care, activities of daily living, pain/discomfort, and anxiety/depression) and each has three levels of severity (no problems, some problems or moderate problems, and severe problems).

severity levels are coded 1 if the response option is "no (I have) problems"; 2 if the response option is "some or moderate problems"; and 3 if the response option is "many problems".

Baseline and up to four weeks
