| Popis: | 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.Eight female adults who perform classical ballet training and feel pain in their foot, but report no injuries in the last 6 months participated in the study. Infrared laser (808 nm) was applied on ballerina's feet twice a week during three months. The laser parameters utilized were 100 mW average optical power and spot size of 0.04 cmThere was a significant increase in plantar arch temperature (1.6 °C for center and 2.3 °C for border, p 0.05) immediately after laser treatment for all ballerinas. The pressure pain thresholds (PPT) were significantly increased for 5 of 7 analyzed sites (p 0.05). Regarding to the static standing balance, the time on one-foot showed a significant increases (from 23 ± 12 s to 34 ± 13 s, p 0.05) only when the test was performed on the left foot (support foot).Then, there were pain relief and improvement of functional performance in ballerinas. The possible mechanism of laser action in reducing pain and thus enhancing performance, like higher blood flow of foot due to an increase of cutaneous temperature, will be discussed. |
