SUMMARY:Environmental Influence on Cognitive-motor Interaction During Whee
 lchair Propulsion
DESCRIPTION:Mikaela Frechette (University of Illinois at Urbana-Champaign,
  Re:Build Tekna); Jacob Sosnoff (University of Kansas Medical Center); and
  Manuel Hernandez and Laura Rice (University of Illinois at Urbana-Champai
 gn)\n\nPurpose: To determine the influence of environmental complexity on 
 cognitive-motor interaction during wheelchair propulsion. Methods: Fourtee
 n participants completed two single- to dual-task trials of Serial-7 Subtr
 action Task and four environments varying in complexity. Differences in co
 gnitive and motor function were determined through paired samples t-tests 
 and percent changes (dual-task costs [DTCs]) were calculated. Within-subje
 cts, repeated-measures ANOVAs were performed to determine differences in D
 TCs across environments. Results: Cognitive function was maintained from t
 he single- to dual-task trial in all environments (p≥0.16) and yielded sim
 ilar DTCs across environments (p=0.80). Compromised motor function was obs
 erved in all environments (p≤0.03) and yielded similar DTCs across environ
 ments (p≥0.37). Conclusion: Wheelchair propulsion is attentionally demandi
 ng; however, environmental complexity did not exacerbate cognitive or moto
 r dual-task costs.\n\n
