SocketSense Össur DS01 Pilot Study

SocketSense Pilot Study Pressure Only Dataset

Intra-socket pressure data collected from QTSS sensors at the socket-liner interface for various tasks.

MAT file contains structure of pressure and gait monitor data collected from the SocketSense system. Pressure values reported in kPa.

Structure format:

data--task--sensor strip location--sensel location pressure

See figure for visual representation of strip and sensel locations in the socket.

Tasks include donning, doffing, walking, ramp, sit-to-stand/stand-to-sit, etc.

sts = sit to stand

sts includes sit-to-stand and stand-to-sit

ramp includes ramp ascent and descent

Gait state is represented numerically as follows:

[1] Unknown

[2] Toe-Off

[3] Mid-Swing

[4] Heel Strike

[5] Mid-Stance

Time vector is given in seconds. Sampling frequency was 20Hz.
