Resumo
Introdução: A osteoartrite (OA) é classificada como uma doença reumática crônica capaz
de causar modificação na integridade da cartilagem articular, e alterações no osso cortical e
na margem articular. Entre as articulações comumente afetadas, a OA de joelho é a
principal responsável pela limitação na locomoção devido à dor, sintoma prevalente da
doença. Para melhora do quadro álgico em pacientes com OA, a fotobiomodulação (FBM)
vem sendo amplamente estudada devido à sua capacidade de promover analgesia, e efeitos
anti-inflamatórios e regenerativos no tecido. Objetivo: Avaliar o efeito da FBM na
intensidade da dor em pacientes com OA de joelho grau IV. Método: Foram selecionados
40 participantes de ambos os gêneros diagnosticados com OA de joelho grau IV,
distribuídos randomicamente em grupo placebo (GP) e grupo fotobiomodulação (GFBM).
O tratamento foi realizado com frequência de 3 vezes por semana durante 4 semanas,
totalizando 12 sessões de FBM, utilizando-se o laser de baixa intensidade AsGaAl (830
nm, 100 mW, 4J por ponto, 80J por joelho) aplicado após um protocolo de equilíbrio. As
avaliações foram realizadas por meio dos questionários KOOS, WHOQOL-abreviado e
LANSS; e através dos testes de limiar de dor por pressão (PPT), Sit to Stand (STS) e
Timed Up and Go (TUG). Resultados: O GFBM apresentou melhora significativa nos
testes STS e TUG, e nos domínios Qualidade de Vida e Físico do questionário WHOQOLabreviado quando comparado ao GP. No teste PPT, ambos os grupos diminuíram o limiar
de dor. Nas demais avaliações, não houve diferença significativa entre os grupos.
Conclusão: O GFBM apresentou melhora mais significativa na funcionalidade quando
comparado ao GP. Porém, mais estudos com diferentes protocolos de aplicação de laser
são necessários para elucidar a questão da intensidade da dor em indivíduos com OA de
joelho grau IV
Introduction: Osteoarthritis (OA) is classified as a chronic rheumatic disease, which causes alterations not only in articular cartilage, but also in adjacent bone structure. The knee, one of the most common affected joints by the disease, can lead to mobility disability due to pain, a major symptom of OA. To decrease pain in patients with OA, photobiomodulation (PBM) has been broadly studied as it is known for promoting analgesia and also by its anti-inflammatory and regeneration effects on tissue. Objective: Evaluate PBM effect on pain intensity of patients with knee OA grade IV. Methods: Forty participants of both genders diagnosed with knee OA grade IV were selected and randomly distributed on placebo group (PG) and photobiomodulation group (PBMG). Treatment was conducted 3 times a week for 4 weeks, which comprehend a total of 12 sessions, it was used a photobiomodulation therapy with an AsGaAl (830nm, 100mW, 4J per point, 80J per knee) applied after a exercise protocol. Evaluations were made through KOOS, WHOQOL-bref and LANSS questionnaires; and with Pressure Pain Threshold (PPT), Sit to Stand (STS) and Timed Up and Go (TUG) tests. Results: PBMG improved on STS and TUG tests and also on Quality of Life and Physical domains of WHOQOL-bref when compared with PG. On PPT test, both groups decreased their pain threshold. Other evaluations demonstrated no difference between groups. Conclusion: PBMG improved more significantly on physical functionality when compared with PG. However, more studies with different laser protocols are needed to analyse the effects on pain intensity of individuals with knee OA grade IV
