【 摘 要 】

Introduction: Ambulation can be used to monitor the healing of lower extremity fractures. However, the ambulatory behavior of tibia fracture patients remains unknown due to an inability to continuously quantify ambulation outside of the clinic. The goal of this study was to design and validate an algorithm to assess ambulation in tibia fracture patients using the ambulatory tibial load analysis system during recovery, outside of the clinic.MethodsData were collected from a cyclic tester, 14 healthy volunteers performing a 2-min walk test on the treadmill, and 10 tibia fracture patients who wore the ambulatory tibial load analysis system during recovery.ResultsThe algorithm accurately detected 2000/2000 steps from simulated ambulatory data. During the 2-min walk test, step counts derived from the algorithm and treadmill showed a strong correlation (r2>0.98) to the visual (“actual”) step count. Applying the algorithm to continuous data from tibia fracture patients revealed qualitative differences in gait be...
