Patients with amyotrophic lateral sclerosis (ALS) experience progressive limb weakness, muscle atrophy, and dysphagia, making them vulnerable to insufficient energy intake. Half of ALS patients suffer from hyper-metabolism.
They enrolled 80 ALS participants at varying stages of their illness, then developed statistical models to estimate TDEE by using factors easily obtained during a routine clinical visit.
Their predictive equations can serve as a basis for recommending placement of a feeding gastrostomy in ALS patients who fail to meet their energy requirements by oral intake.
They developed a Web-based calculator, but it seems to not work anymore.
I tried to replicate this calculator.
