RESEARCH QUESTION: How does prolonged walking-induced fatigue affect lower limb muscle activity, plantar pressure distribution, and tripping risk? METHODS: Eighteen elderly adults walked fast on a treadmill for 60 minutes at a fixed speed. The plantar pressure was measured with an in-shoe monitoring system, eight lower limb muscles were monitored using surface electromyography, and foot movements were tracked by a motion capture analysis system...
