Rebox effect on exercise-induced acute inflammation in human muscle.
OBJECTIVE
To evaluate the effect of Rebox stimulation on an experimental model of soft tissue inflammation.


METHODS
Randomized trial, partially blinded, comparing a control group with active and placebo Rebox.


METHODS
Thirty healthy volunteers, 15 women.


METHODS
Delayed onset muscle soreness was induced in biceps brachii muscle by weighted eccentric exercise. Rebox stimulation was applied daily for 3 days using a negatively charged probe electrode, at pulse duration of 100 microsec, amplitude of 160 microamp, and frequency of 3000 Hz.


METHODS
DAILY ratings of pain by visual analogue scale (VAS), and tenderness by pressure-pain threshold (PPT) and pressure-pain tolerance (PT).


RESULTS
Significant increases in VAS and decreases in PPT and PT were found at 24 and 48 hours. There were no differences between groups.


CONCLUSIONS
Rebox had no effect on this experimental model of soft tissue injury.
