Intervention model description: To evaluate the immediate and long-term effects of infrared laser on classical ballerinas' feet.
Primary purpose: TREATMENT

Brief 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.

Detailed description: High risk of injuries and painful symptoms in athletes and dancers (especially classical ballerinas) may lead to reduced functional performance. The use of photobiomodulation may improve functional performance in ballerinas that are affected by foot pain. An aluminum gallium arsenide (AlGaAs) diode laser device was uded. Infrared laser (808 nm) was applied on ballerina's feet twice a week during three months. Thermography, algometry and unipodal static standing balance test were performed. There were pain relief and improvement of functional performance in ballerinas.
