Summary

Overuse injuries and painful symptoms in athletes and dancers (especially classical ballerinas) may lead to reduced functional performance. However, laser application may reduce pain and increase physical conditioning. The aim of the current study was to evaluate the immediate and long-term effects of infrared laser on classical ballerinas' feet. The hypothesis investigators was that the infrared laser would be able to reduce pain perception and enhance functional performance in ballerinas.

DEVICE

Infrared Laser

An aluminum gallium arsenide (AlGaAs) diode laser device (Twin laser, MMOptics, São Carlos, SP, Brazil) was used. The irradiation parameters were as follows: infrared laser (808 nm wavelength) with a spot area of 0.04 cm2, and an average optical power of 100 mW operated in a continuous mode during 1 minute per point, leading to an irradiance of 2,500 mW/cm2, energy of 6 J and fluence of 125 J/cm2 per point. The laser was applied on ballerina's feet twice a week during three months.
