Abstract des Autors

Objective: To determine whether grasping the handrails during treadmill walking affects sagittal plane kinematic parameters selected to describe walking style. Design: Crossover trial. Setting: A university motion analysis laboratory. Participants: A convenience sample comprised of 15 apparently healthy college-age volunteers. Intervention: After being acclimatized to treadmill walking, subjects were videotaped while completing two treadmill walking bouts. Each bout was 10 minutes in duration and was conducted at a walking speed of 1.5m/sec. Subjects were instructed to grasp the handrails in one bout (GRASP) but to refrain from using the handrails in the other (FREE). Both bouts were conducted in a single session and were separated by a 10-minute rest period. The order in which subjects completed the bouts was randomized. Main Outcome Measures: Five successive strides occurring during the last 30 seconds of each bout were digitized. The coordinate data were numerically filtered and the following parameters derived: stride length, percentage of stride cycle spent in double-support, and the hip, knee, and ankle angles at heel-strike and toe-off. The results for the five strides in each bout were averaged and the average value was used in the statistical analysis. The FREE and GRASP conditions were compared with t tests for dependent samples. Results: There were no differences between the FREE and GRASP conditions for any of the parameters assessed. Conclusions: Subjects may grasp the treadmill handrails without affecting sagittal plane kinematic parameters of walking style. Verf.-Referat
