When measurement error equals the clinical effect: designing a wearable knee monitor
On a wearable knee monitor built on inertial sensors, published measurement error against optical motion capture runs 4 to 9 degrees, and the gait deficits it has to detect after total knee arthroplasty run 4.8 to 6.6 degrees. The defensible claim is change within one patient over weeks, not an absolute angle, with a flexion […]
Load sensing is solved. Adherence is the product.
On a rehabilitation crutch that doses limb loading, the load cell is the solved part. Published measurement accuracy sits near an intraclass correlation of 0.97, while published compliance with partial weight bearing runs between zero and 38 percent. The engineering budget belongs in the feedback loop: feedback that arrives within the step and never asks […]
Orthopedic device development: the hard parts and how teams handle them
Orthopedic and rehabilitation devices tend to get into trouble in the same places. Implants carry cyclic load for years, sensors sit next to metal, wearables slide over soft tissue, and patients use the device at home with nobody watching. Orthopedics is one of the main areas at OVA Solutions, a medical device engineering group of […]
