Falls in the elderly: Part I, Gait.
The aim of this study was to determine a gait profile of two groups of elderly adults: one with a history of falls and one without a history of falls. The following gait characteristics were identified: step frequency, stance time, swing time, double support time, step length, heel width, heel height, toe height, and hip, knee, and ankle angular excursion. The history of falls group was composed of 25 subjects (seven men and 18 women), and the no history of falls group was composed of 30 subjects (12 men and 18 women). Two 16-mm Locam cameras were used to film the subjects. Each subject was filmed while walking on a motorized treadmill at 4 km/h and 6 km/h. The film data were digitized on a sonic digitizer interfaced to a VAX computer. The ANOVA statistic indicated significant (p less than .05) difference between the two independent variables for heel width. There appears to be no significant relationship between the studied gait characteristics (other than heel width) and falls in apparently healthy elderly individuals.
