Little is known about arm swing asymmetry in overground walking. We report directional (dASI) and non-directional arm swing symmetry indices (ndASI) from 334 adults (mean age 68.6 ± 5.9 y) walking overground at comfortable (NW) and fast (FW) speeds and while completing a serial subtraction task (DT). dASI and ndASI were calculated from sagittal shoulder range of motion data generated by inertial measurement units affixed to the wrist. Most $(91\%)$ participants were right-handed. Group mean arm swing amplitude was significantly larger on the left in all walking conditions. During NW, ndASI was 39.5 ± 21.8, with a dASI of 21.9 ± 39.5. Distribution of dASI was bimodal with an approximately 2:1 ratio of left:right-dominant arm swing. There were no differences in ndASI between conditions but dASI was smaller during DT compared to FW (15.2 vs 24.6; p = 0.009). Handedness was unrelated to ndASI, dASI or the change in ASI metrics under DT. Left-dominant arm swing is the norm in healthy human walking irrespective of walking condition or handedness. As disease markers, ndASI and dASI may have different and complementary roles.}, keywords = {Aged / Aged, 80 and over / Arm: physiology / Biomechanical Phenomena / Female / Functional Laterality / Humans / Linear Models / Male / Middle Aged / Walking: physiology}, cin = {AG Maetzler / Ext UKT-Trend / AG Gasser / AG Berg ; AG Berg}, ddc = {600}, cid = {I:(DE-2719)5000024 / I:(DE-2719)5000056 / I:(DE-2719)1210000 / I:(DE-2719)5000055}, pnm = {344 - Clinical and Health Care Research (POF3-344) / 345 - Population Studies and Genetics (POF3-345)}, pid = {G:(DE-HGF)POF3-344 / G:(DE-HGF)POF3-345}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:30143717}, pmc = {pmc:PMC6109135}, doi = {10.1038/s41598-018-31151-9}, url = {https://pub.dzne.de/record/140157}, }
