Brief summary

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.

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.

Interventions

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.

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.

Design outcomes

Primary

MeasureTime frameDescription
Change in Pain assessed by VASBaseline and up to four weeksThe 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.
Change in WOMAC questionnaireBaseline and up to four weeksThe 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.
Change in the quality of life testBaseline and up to four weeksThe 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.
