Secondary Outcomes: RST led to significant increases in cough peak inspiratory flow (p=0.02), however, did not impact cough expiratory flow (p = 0.06) or FVC (p=0.60). Twelve-Month Outcomes: A significant difference in ALSFRS-R Bulbar subscale slope was observed across treatment groups, with a more than two-fold faster rate of bulbar decline in the sham versus active-RST groups observed (-0.29 vs. -0.12 points/month, p=0.02). Total ALSFRS-R slope, feeding status, and time to NIV did not differ across treatment groups (p >0.05).Conclusions: RST was well tolerated and led to improvements in some, but not all, short- and long-term outcomes. RST represents a proactive rehabilitative intervention that could increase physiologic capacity of specific breathing and airway clearance functions during the early stages of ALS. Further work is needed to determine optimal training intensity, resistance load specifications, and potential long-term functional outcomes. ER -
