UNASSIGNED: Despite the ubiquity of gait assessment in clinic and research, it is unclear how observation impacts gait, particularly in @entity1 with @entity1118 and @entity1642 . We compared temporal spatial gait patterns in @entity1 with and without @entity1643 ( @entity1643 ) when they were aware and unaware of being observed. This was a repeated-measures, deception study in 55 healthy @entity1 (32.0  12.4 yr, 24.2  2.7kg/m(2)) and @entity1 with @entity1643 (51.9  17.9 yr, 27.8  4.4kg/m(2)). @entity1 performed one condition in which they were unaware of observation (UNW), and three conditions under investigator observation: (1) aware of observation (AWA), (2) investigators watching cadence, (3) investigators watching step length. @entity1 walked across an 8.4m gait mat, while temporal spatial parameters of gait were collected. The Medical Outcomes Short Form (SF-12), Beck @entity308 Inventory (BDI), State Trait @entity148 Inventory (STAI), and @entity717 Index (ODI) were completed. Significant condition by group interactions were found for velocity and step length (p<0.05). Main effects of study condition existed for all gait variables except for step width. Main effects of group (healthy, @entity5752 ) were significant for all variables except for step width (p<0.05). Regression analyses revealed that after accounting for age, sex, and SF-12 mental component score, BDI scores predict velocity changes during walking from the UNW to AWA conditions. These findings show that @entity1 change their gait patterns when being observed. Gait analyses may require additional trials before data can reliably be interpreted and used for clinical decision-making.
