Lower limb loading assessment systems and methods
First Claim
1. A lower limb loading assessment system comprising:
- at least one wearable motion sensor releasably securable to a subject'"'"'s lower limb that is configured to sense the tibial shockwaves experienced by the lower limb as the subject performs a repetitive physical activity involving repetitive footstrikes of the lower limb with a surface, the wearable motion sensor comprising an accelerometer that is configured to sense acceleration data in at least three orthogonal axes and generate representative multi-axis acceleration data over a time period associated with the physical activity, the wearable motion sensor generating tibial shockwave data comprising the generated multi-axis acceleration data which represents a series of discrete tibial shockwaves from the discrete footstrikes; and
a data processor that is configured to receive and convert the tibial shockwave data comprising the multi-axis acceleration data sensed by the wearable motion sensor into resultant acceleration magnitude data, and wherein the data processor is configured to process the resultant acceleration magnitude data to generate output feedback data comprising data to assist the subject to minimize future loading in their lower limbs.

Abstract
A lower loading assessment system having at least one motion sensor mounted to a subject'"'"'s lower limb that is configured to sense the tibial shockwaves experienced by the lower limb as the subject performs a repetitive physical activity involving repetitive footstrikes of the lower limb with a surface. The motion sensor comprises an accelerometer that is configured to sense acceleration data in at least three axes and generate representative acceleration data over a time period associated with the physical activity. The acceleration data represents a series of discrete tibial shockwaves from the discrete footstrikes. A data processor receives the tibial shockwave data and processes that to generate output feedback data comprising data to assist the subject to minimize future loading in their lower limbs.
