Abstract

The use of an obstacle course to quantify gait, balance and functional mobility in elderly persons, particularly to assess objectively changes following exercise and rehabilitation interventions, has not been extensively developed or tested. In this study, we describe an 18-item obstacle course developed as an outcome measure for an exercise intervention among fall-prone elderly men. Reliability and validity of the obstacle course was tested in a group of 58 community-living elderly men (mean age=75 years). Each subject’s performance was videotaped and timed. The videotapes were scored by a physical therapist and a physician. Inter-rater reliability between the raters was high (Kappa =0.96, p<0.0001). Both the obstacle course score and time correlated significantly with gait velocity, a 6-minute walk test, and a performance-oriented instrument of gait and balance. Obstacle course scores showed significant improvement among the most impaired subjects, but not among higher functioning subjects following a 3-month exercise intervention. These results suggest that an obstacle course may be a useful and valid method for measuring outcomes related to mobility tasks in selected elderly populations. Further work is needed to determine in which populations, and for which outcomes, an obstacle course is better than simpler performance-based measures.
