RG mice exhibit normal muscle physiology compared to C57BL/6 WT mice. All measurements shown here were normalized to the estimated cross-sectional area of each muscle. a, b Measurements of direct stimulation of muscle fibers. c, d Measurements of muscle twitch after nerve stimulation. e, f Estimates of synaptic efficiency using the data from direct and indirect stimulation. n = 3 age and sex-matched mice per group. There was no significant difference (as defined as p < 0.05) between any RG and C57BL/6 groups
