Benchmark datasets for bilateral lower limb neuromechanical signals from wearable sensors during unassisted locomotion in able-bodied individuals

This dataset, the ENcyclopedia of Able-bodied Bilateral Lower Limb Locomotor Signals (ENABL3S), represents a benchmark for lower limb neuromechanical signals recorded using wearable sensors from 10 able-bodied individuals during unassisted locomotion. In addition to sitting and standing, subjects freely transitioned between level ground walking, ramp ascent/descent, and stair ascent/descent at their self-selected speed. Subjects were bilaterally instrumented with surface electromyography (EMG) from seven lower limb muscles, goniometers at the knee and ankle, and inertial measurement units (IMU) at the shank, thigh. An additional IMU was worn around the waist. Features commonly used in lower limb intent recognition for prosthesis control have been extracted from windows near heel contact and toe off gait events.
