Efficacy of Microcurrent Therapy After Eccentric Exercise

Status Completed

Clinical Trial Summary

15 participants will be included in the present study. They will attend two groups of three sessions (i.e. sessions 1-2-3 and sessions 4-5-6) spaced by 3 months:

- session 1 and 4 (performed a few days before the experimental session): session for participants to get familiarized with the test battery.

- session 2 and 5: experimental session (the test battery followed by the provocative task, the test battery, the one-hour "treatment" and the test battery again).

- session 3 and 6 (performed 2 days later): the test battery.

The test battery included flexibility, functional, pressure pain threshold tests.

The provocative task was an isokinetic eccentric task for knee flexors and extensors.

The treatment was either a microcurrent therapy or a placebo microcurrent therapy.

Clinical Trial Description

Objective:

To study the efficacy of microcurrent to reduce DOMS (Delayed Onset Muscle Soreness) occuring after an eccentric exercise

Methods:

Experimental protocol

Participants will attend two groups of three sessions (i.e. sessions 1-2-3 and sessions 4-5-6) spaced by 3 months:

- session 1 and 4 (performed a few days before the experimental session): session for participants to get familiarized with the test battery.

- session 2 and 5: experimental session: the test battery followed by the provocative task, the test battery, the one-hour "treatment" (real microcurrents at one of the session and placebo microcurrents at the other one) and the test battery again.

- session 3 and 6 (performed 2 days later): the test battery.

Before starting session 2, patients will be randomized into the microcurrent group or the placebo microcurrent group. Three months later, participants will change of group.

The Test Battery: it will be conducted by a blind (to the treatment) investigator. It will include knee flexor and extensor flexibility tests, a functional test (unilateral " counter-movement jump "), a pain to measure pain threshold of thigh muscles and an isometric maximal voluntary contraction (MVC) test of knee flexors and extensors.

The Provocative task: 40 isokinetic eccentric contractions of knee flexors and extensors.

The one-hour Treatment: with the participant lying on an examination table, several electrodes were located over the muscles involved in the provocative task. The microcurrent therapy was then started. It was stopped after 5 seconds in the "Placebo group" and after one hour in the real "Microcurrent group". The microcurrents were delivered by the machine B-E-St®.

Follow-up: in addition to the 48hours follow-up (session 3/6), participants will fill in a pain visual analogue scale each day after the session 2/5. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
