dc.description.abstractBackground: When performing a second task, normal gait parameters are altered as compared to normal walking. Purpose: The purpose of this study was to determine the effects of performing a task on gait parameters including number of steps, step width, step length, and stride length. Hypotheses: It was predicted that walking at a fast-pace would decrease number of steps and step width while increasing stride length and step length. Carrying 15% of the subjects body weight would increase number of steps and step width while decreasing stride length and step length. Performing mental math would increase number of steps, step width would deviate from normal, and step length and stride length would decrease. Methods: Nine male and female students ages 19-26 participated in the study. Six conditions during walking were performed by each subject for a total of 18 7-m trials. Measurements were taken including number of steps, step width, step length, and stride length. Ttests were performed to statistically analyze the data. Results: There was a statistically significant difference found between normal walking and fast-paced walking in number of steps, step length, and stride length, but not step width. No other statistically significant data was found. Conclusions: Gait is not significantly altered when performing a second task, with the exception of fast-paced walking. Further studies should be done with an increased sample size.en_US
