  1. Mean (SD) unless stated otherwise. Two patients did not tolerate the MUNIX procedure. Two missing measurements for Ki67 staining and 1 missing for NCAM expression due to insufficient antibody binding. SMI Skeletal muscle index, IGF-I Insulin-like growth factor 1, IGFBP-3 Insulin-like growth factor binding protein 3, ALS Acid labile subunit, MUNIX Motor unit number index, MUSIX Motor unit size index, NCAM neural cell adhesion molecule. p-values between groups were calculated using two sample-t-test. p-Values <.05 are bold
