Previous issue date: 2017-03-02 === A fibromialgia ? uma doen?a que apresenta dor musculoesquel?tica cr?nica e difusa associada a fadiga, dist?rbio do sono, problemas cognitivos e baixos n?veis de condicionamento f?sico. Trabalhos recentes mostram bons resultados tanto com a pr?tica de exerc?cios funcionais quanto com a utiliza??o da terapia laser de baixa intensidade (TLBI) para reduzir os sintomas dessa popula??o. Por?m, n?o foram encontradas evid?ncias que associem as duas formas de terapia no tratamento da fibromialgia. Objetivo: Investigar os efeitos de um programa de exerc?cios funcionais associado ? TLBI na dor, desempenho funcional e qualidade de vida de indiv?duos com fibromialgia. M?todos: Trata-se de um ensaio cl?nico randomizado e duplo-cego composto por 22 mulheres divididas em dois grupos de forma aleat?ria em blocos: grupo placebo (n=11) que foi submetido a um programa de exerc?cios funcionais associado a TLBI placebo; e o grupo laser (n=11) que foi submetido ao mesmo programa de exerc?cios associado a TLBI ativa. O programa de exerc?cio teve dura??o de dois meses e frequ?ncia de tr?s vezes semanais. A TLBI (808nm; 100mW; 4J e 142,85 J/cm2 por ponto) foi aplicada imediatamente ap?s cada sess?o de exerc?cio em diferentes pontos dos m?sculos quadr?ceps (8), isquiotibiais (6) e tr?ceps sural (3), bilateralmente. Todos os indiv?duos foram submetidos a avalia??es pr? e p?s interven??o quanto a: dor (locais, intensidade e limiar), desempenho funcional (equil?brio, testes funcionais), desempenho muscular (flexibilidade e vari?veis isocin?ticas), depress?o e qualidade de vida. A an?lise estat?stica foi realizada por meio do SPSS 20.0 adotando um intervalo de confian?a de 95%. Resultados: Pode-se observar que houve uma redu??o da dor e melhora do desempenho funcional e muscular, da depress?o e qualidade de vida em ambos os grupos (p<0,05), por?m, sem diferen?as significativas entre eles (p>0,05). Conclus?o: O programa de exerc?cio funcional foi eficaz na melhora da dor, desempenho funcional e qualidade de vida de indiv?duos com fibromialgia. No entanto, a TLBI n?o promoveu um incremento nos efeitos positivos proporcionados pelo exerc?cio. === Background: Fibromyalgia is a disease that presents chronic and diffuse musculoskeletal pain associated with fatigue, sleep disturbance, cognitive problems and low levels of physical conditioning. Recent studies have shown good results both with the practice of functional exercises or with the use of low-level laser therapy (LLLT) to reduce the symptoms of this population. However, no evidence was found associating both forms of therapy in the treatment of fibromyalgia. Objective: To investigate the effects of a LLLT associated with an exercise program on pain, functional capacity and quality of life of individuals with fibromyalgia. Methods: It was performed a randomized, double-blind clinical trial with 22 women randomly divided into two blocked groups: placebo group (n = 11) who went through a functional exercise program associated with placebo LLLT and the laser group (n = 11), who underwent the same functional exercise program associated with active TLBI. The exercise program occurred in two months and three times a week. The LLLT (808nm; 100mW; 4J e 142,85 J/cm2 per point) was applied right after each exercise program session in different points of quadriceps (8), hamstrings (6) and sural tr?ceps (3), bilaterally. Both groups were submitted to an evaluation of pain (sites, intensity and threshold), functional capacity (balance, functional tests), muscle performance (flexibility and isokinetic variables), depression and quality of life, before and after the intervention. Statistical analysis was performed using SPSS 20.0 adopting a 95% confidence interval. Results: It was observed that there was a reduction of pain and depression levels and an improvement of functional capacity, muscular performance and quality of life in both groups (p<0.05), but with no significant differences among them (p>0.05). Conclusion: The functional exercise program was effective on pain relief, better functional capacity and quality of life of individuals with fibromyalgia. However, LLLT did not promote an increase on the positive effects caused by the exercise.
