Lombalgia crônica em pacientes com lúpus eritematoso sistêmico: prevalência e preditores da força muscular de extensão de tronco e sua correlação com a incapacidade

The prevalence of CLBP in individuals with LES was 26%. The MVIC of the back muscles was 63% predicted by five variables of interest, however, only the handgrip strength was a statistically significant predictive variable. The MVIC of the back muscles presented a linear relation directly proportional to handgrip and inversely proportional to Oswestry Index i.e. stronger back muscles are associated with lower disability scores.
