Abstract
Demo abstract. Partial weight-bearing instructions are poorly followed. This device streams load data to a clinician dashboard for early corrective feedback.
Description
The prototype prioritised battery life and washability over sensor density, based on early user feedback.
Validation compared insole output with force-plate measurements in a gait lab.
Innovation / discovery
Reporting adherence as a weekly percentage rather than raw data made the output usable in a normal clinic appointment.
Surgical / procedural method
Four-zone pressure sensing, Bluetooth logging, validation against force plates, pilot deployment after lower-limb fracture fixation.
Research findings
- Insole load estimates tracked force-plate values within acceptable error in the demo validation.
- Adherence improved after patients saw their own weekly reports.
- Sensor drift required recalibration at around eight weeks.
