简要总结
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.
详细描述
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.

结局指标
主要结局
Analysis of pain for feet by algometry
时间窗: 3 months
Pressure pain thresholds (PPT) were assessed with an electronic algometer. The pressure was applied and the ballerinas were instructed to ask to say "stop" when the sensation changed from pressure to pain. Three PPT measurements were performed to obtain an average.
Analysis of pain for feet by the visual analogue pain intensity scale
时间窗: 3 months
A continuous scale comprised of a horizontal line with 10 centimeters in length was used. All ballerinas were instructed to make a mark with a pen at any point on the line between 2 verbal descriptors, one for each symptom extreme \["No pain" (score=0) and "as bad as it could be" or "worst imaginable pain" (score=10)\].
