Non-invasive load measurement in the human tibia via spectral analysis of flexural waves

Ali Yawar, Daniel E. Lieberman, Daniel H. Aslan

Peak locations in tibial flexural wave spectra vary linearly with compressive force and serve as non-invasive proxies for bone load.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Under physiological conditions, peak locations in the wave acceleration spectra vary linearly with the compressive force on the tibia and may be used as proxies for the compressive force.

C2weakest assumption

That soft tissue and skin interfaces do not substantially distort the flexural wave spectra from the underlying bone, allowing skin-mounted sensors to accurately capture load-dependent bone wave behavior as predicted by the Euler-Bernoulli model.

C3one line summary

Tibial compressive force correlates linearly with the frequency location of peaks in flexural wave acceleration spectra, allowing non-invasive proxy measurement via skin-mounted transducers and accelerometers.
