The goal of functional outcomes working group is to identify standardized functional measures appropriate for use as endpoints in NF clinical trials.  Our group reviews measures for types of physical functioning that can be affected by NF, including hearing, facial function, pulmonary function (breathing), walking and sleep. 

Current group leader: Scott Plotkin, MD, PhD

Current Work

Currently, we are working on the designing a trial to establish the reliability of hand-held dynamometry (HHD) for measurement of strength in individuals with NF.   We also researching the possibility of designing a trial to establish the validity of measuring swallowing function.
