Abstract

- Haptic feedback refers to the external vibratory cue that is activated by data picked up by the haptic device, Inertial Measurement Unit (IMU) (Figure 1), which senses joint position.

- Position-driven haptic touch input can modify movement in real-time (Meszaros, 2019)

- Original goal: to reduce knee hyperextension during gait using a popliteal fossa tactor driven by an IMU-based angle sensor (Sagemotion)

-Concerns arose on the validity of IMU/tactor and markerless motion analysis ❏ Are these algorithm-based data technologies clinic-ready?

- Does Sagemotion IMU fire the tactor at the actual knee angle selected in its software?

- Can markerless motion analysis accurately sense knee hyperextension in adult gait?
