Thus, we hypothesized that intradialytic NMES would attenuate the loss leg lean mass and improve the phase angle in patients undergoing hemodialysis (HD). Methods: A randomized controlled trial was performed with twenty-one adult HD patients (n = 8 F, n = 13 M; 45.8 +/- 10.6 y) randomly assigned to usual care (control group, n = 11; 4F/7M) or to the NMES group (n = 10; 4F/6M). NMES was applied bilaterally at the origin and insertion points of the quadriceps or gastrocnemius muscles for 40 min during each HD session (3x/wk for one month). Pre-and post-intervention, we measured leg lean mass using dual-energy x-ray absorptiometry and phase angle using bioelectrical impedance analysis. Results: NMES did not change leg lean mass compared to the control group. Phase angle increased in the NMES compared to the control group (Delta: +0.71 +/- 0.27 degrees vs. -0.46 +/- 0.23 degrees, p = 0.004) with interaction time x treatment (ANOVA p = 0.004). Conclusion: Short-term intradialytic NMES targeting muscles of the legs improved the phase angle but did not change leg lean mass. Brazilian registry of clinical trials under the code: RBR-98wzgn.
