Detaljeret beskrivelse
There is a growing body of clinical evidence which shows that noninvasive, nonpharmacologic pulsed electromagnetic fields have many clinical effects. Pulsed electromagnetic fields have shown to reduce pain in different groups of patients. This concerns patients with osteoarthritis, rheumatoid arthritis, diabetic neuropathy, fibromyalgia, distal radius fractures, pelvic pain and postoperative patients.
A marathon is a muscular strain. Physiologic effects of a marathon involves muscular and connective tissue damage which initiates an inflammatory response as well as release of metabolic factors like lactate and free radicals, intracellular metabolites and by-products of proteolysis.
The objective of this study was to investigate the efficacy of pulsed electromagnetic fields compared to placebo in reducing delayed onset muscle soreness in marathon runners.

|---|---|

Eksperimentel: Active pulsed electromagnetic field
|
Every person received two active devices.
The devices emitted 2-ms bursts of 27.12 MHz sinusoidal waves repeating at 2 bursts/s.
Peak magnetic field intensity was 0.05 G which induced an average electric field of 10 mV in the tissue with an effect of 7.3 mW/cm3.

Every persons received two sham pulsed electromagnetic field devices.

Thigh pain by walking
Tidsramme: 5 days
|
Primary outcome of thigh pain during semi-squat during 5 days following the marathon showed a significantly lower pain among the active group compared to the placebo group. The outcome was thigh muscle pain measured on a 10 cm visual analog scale during a squat of 90 degrees three times a day; when they woke up, at 12 pm and 8 pm. |
