Validity of the Mini‐BESTest in adults with myotonic dystrophy type 1

Introduction Myotonic dystrophy type 1 (DM1) is a multisystemic neuromuscular disease that causes balance problems. The objective of this study was to assess the construct validity of the Mini‐BESTest among adults with DM1. Methods Fifty‐nine individuals with late‐onset or adult phenotypes of DM1 we...

Summary:Introduction Myotonic dystrophy type 1 (DM1) is a multisystemic neuromuscular disease that causes balance problems. The objective of this study was to assess the construct validity of the Mini‐BESTest among adults with DM1. Methods Fifty‐nine individuals with late‐onset or adult phenotypes of DM1 were recruited. Participants performed the Mini‐BESTest, 10‐Meter Walk Test (10mWT), 6‐Minute Walk Test (6MWT), and Timed Up & Go (TUG) and were questioned on their tendency to lose balance and whether they fell in the past month. Results Scores on the Mini‐BESTest were significantly different between phenotypes and CTG repeat numbers (P
