Mello Paula R. Serrão Roberta P. Luz Lia R. Bittencourt Stela M. Mattiello Salud knee osteoarthritis rehabilitation muscle strength sleep apnea syndromes Objective: The aim of this study was to investigate whether obstructive sleep apnea (OSA) alters the fluctuation of submaximal isometric torque of the knee extensors in patients with early-grade osteoarthritis (OA). Method : The study included 60 male volunteers, aged 40 to 70 years, divided into four groups: Group 1 (G1) - Control (n=15): without OA and without OSA; Group 2 (G2) (n=15): with OA and without OSA; Group 3 (G3) (n=15): without OA and with OSA; and Group 4 (G4) (n=15) with OA and with OSA. Five patients underwent maximal isometric contractions of 10 seconds duration each, with the knee at 60° of flexion to determine peak torque at 60°. To evaluate the fluctuation of torque, 5 submaximal isometric contractions (50% of maximum peak torque) of 10 seconds each, which were calculated from the standard deviation of torque and coefficient of variation, were performed. Results : Significant differences were observed between groups for maximum peak torque, while G4 showed a lower value compared with G1 (p=0.005). Additionally, for the average torque exerted, G4 showed a lower value compared to the G1 (p=0.036). However, no differences were found between the groups for the standard deviation (p=0.844) and the coefficient of variation (p=0.143). Conclusion : The authors concluded that OSA did not change the parameters of the fluctuation of isometric submaximal torque of knee extensors in patients with early-grade OA. 2015 artículo científico 1413-3555 https://www.redalyc.org/articulo.oa?id=235041372004 en http://www.redalyc.org/revista.oa?id=2350 Revista Brasileira de Fisioterapia application/pdf Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia Revista Brasileira de Fisioterapia (Brasil) Num.4 Vol.19 |
