Efeito da fotobiomodulação e da cinesioterapia na expressão de índices hematológicos em pacientes com osteoartrose de joelho

Abstract

Photobiomodulation (PBM: English-photobiomodulation) is a treatment that involves the use of a monochromatic light source, non-thermal effect, which has been proposed in the treatment of patients with knee osteoarthrosis (OAJ), due to these analog, action effects anti-inflammatory and regenerative. However, the systemic effects of PBM, especially those referring to monomorphonuclear blood cells, are still unclear. The aim of this study was to evaluate the number of white series cells and the number of patients diagnosed with OAJ published through PBM and kinesiotherapy, associated or not. The number of cells in the white and platelet series of 28 patients, between 45 and 80 years old, were randomly divided into 4 groups: Kinesiotherapy Group (CG); PBM Group (GL); Cinesioterapia + PBM Group (GCL); and PBM + Cinesioterapia Group (GLC). All groups receive treatment 3 times a week on alternate days for 4 weeks. Groups using treatment with physical activity (CG, GLC and GCL) perform supervised exercises and groups using treatment with PBM (GL, GCL and GLC) receive 9 irradiation points (Therapy XT-DMC, São Carlos, Brazil - 808nm P = 100mW - 3J / point). The evaluations were performed before the start of treatment (AV0) and 48 h after the end of the 10th session (AV1). Our results show that the initial and final count is not the number of neutrophils, lymphocytes, monocytes and platelets, the GC, GCL and GLC do not significantly alter cell counts (p0.05). The GL showed a significant increase only in the monocyte count (p0.05) after 4 weeks of treatment. The comparison between cell relationships between lymphocytic neoplasms (RNL), monocyte lymphocytes (RML) and coated lymphocytes (RPL), did not significantly affect the use of any method used. However, an RML in the intergroup evaluation showed an increasing trend only in the group treated with PBM. Therefore, we can conclude that PBM alone, without OAJ treatment, was the only treatment capable of promoting white cell and platelet count, mainly in monocytes. And an RML relationship was also a single cellular relationship capable of differentiating the proposed procedures, suggesting that PBM alone can increase the inflammatory response, in the tests tested.
