Effects of Invasive Techniques in Myofascial Trigger Points: A Randomized Controlled Clinical Trial
Effects of Invasive Techniques in Myofascial Trigger Points: A Randomized Controlled Clinical Trial
Myofascial pain syndrome (MPS) is present in up to 87% of the patients that present pain. MPS usually presents painful myofascial trigger points (MTrPs).
One methodology used to quantify the pain in MPS is the algometry, which measures the pressure pain threshold (PPT).
Invasive techniques in physiotherapy have become popular in the last years due to their clinical efficacy and evidence. Percutaneous Microelectrolysis (MEP®) and dry needling are techniques that are already in use for this syndrome.
MEP® is a technique that employs a galvanic current up to 990 microAmperes, which is applied percutaneously with an acupuncture needle connected to the cathode. It is also known as low intensity percutaneous electrolysis.
The aim of this study is to compare the effects in pain and muscle tone (measured with algometry and surface electromyography) of invasive techniques. Healthy subjects between 18 to 48 years old, both sex, presenting MTrPs in upper trapezius will be recruited.
The secondary objectives are to determine the discomfort degree of each technique and if it is better to use MEP® with a fixed dose or with an algorithm in which the dose varies.
The hypothesis, according to our previous studies, is that MEP® generates higher changes in PPT.
