LocoD - TFA

Our Data Repository consists of data from 5 participants with transfemoral amputation and osseointegration.

The recorded data corresponds to one recording per participant digitalized at 2 kHz. Data includes 8 EMG (Delsys) channels, 3 IMUs (Delsys), and one pressure sensor (Delsys).

Data consists of 30 trials of our circuit. Our circuit contains terrains for walking, stair ascent, stair descent, ramp ascent, and ramp descent. Data were tagged when the subjects started a terrain manually by an operator.

real time data consists of 15 trials.

SEMG electrodes were placed on the semitendinosus, biceps femoris, tensor fasciae latae, rectus femoris, vastus lateralis, vastus medialis, and gracilise. These muscles were found using palpation by an experienced physiotherapist and were selected based on a literature search for the most common muscle signals used to control lower limb prosthetics.

IMUs were placed above the knee, below the knee, and on the foot to get all the joint orientations during different movements.

A Pressure sensor was built into an insole used by each research participant.

Participants were instructed to enter each terrain, such as stairs or ramps with their sensorized legs. These different locomotion modes were selected as they are the most common movements in daily life.
