Inertial measurement units worn on the dorsum of the foot and proximal to the ankle can provide valid slip recovery measures.

ABSTRACT:

Background

Slips are a leading cause of injury among older adults. Slip recovery measures are often captured using optoelectronic motion capture (OMC) systems that can be costly and typically require a laboratory setting. Inertial measurement unit (IMU) systems show promise as a lower cost, portable, and wearable form of motion capture.

Question

Can IMUs worn on the dorsum of the feet and proximal to the ankles be used to capture valid slip recovery measures?

Methods

Thirty older adults (ages 65-80; 18 females) were exposed to a laboratory slip while wearing OMC markers, IMUs on the dorsum of the feet, and IMUs proximal to the ankles. To evaluate the concurrent validity of IMU-based slip recovery measures using the OMC-based measures as our standard, we determined whe
