The aim of this study is therefore to validate Myant SKIIN garments for the purpose of gait and balance assessment. To achieve this, we recruit young healthy adults from the University of Waterloo to wear Skiin products (see Fig. 1). Participants will be asked to perform a number of scripted gait and balance tasks.
Specific objectives of this study are:
Gait metrics from Skiin garments will be compared to metrics from a gold standard measurement (Vicon motion capture) to indicate accuracy, precision and reliability.

| Skiin garment and pods | Device | Participants will be asked to wear a Skiin smart garment over their own clothes. Small motion capture markers will be placed on their body and pressure-sensitive insoles placed into their shoes to measure the pressure underneath their feet during the study tasks. Once the sensors are ready for collection, participants will be asked to complete 5 tasks associated with their daily activities: 1. Locomotion; 2. Lower limb strength - repeated sit-to-stand-to-sit transitions; 3. Lower limb strength and locomotion - Timed Up and Go; 4. Free walking during a 2min walk; 5. Standing balance, postural control. |
