SocketSense Össur DS01 Pilot Study
Description
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.
