Abstract/OtherAbstract:
Studies documenting the forces that are transmitted through a walker's frame are still scant. The purpose of this study was to evaluate the pattern and magnitude of forces that are transmitted through the frame of a walker during ambulation. A standard aluminum walker was instrumented. Gauges, which were mounted on all four legs, recorded axial, frontal, and sagittally oriented forces. A custom made computerized system registered the forces during 30 seconds of data acquisition. Twelve patients with ambulation dysfunction were tested with this system. Two different usage patterns emerged from the study. One usage pattern was observed in patients who were using the walker as a mean to reduce the amount of weight transmitted through the lower extremity. The second pattern was observed in patients with severe balance problems. These patients used the walker to enhance their balance and stability. The system described allows walker usage pattern analysis. Better understanding of force distribution and usage patterns may lead to improved or new walker design.
