Electrical Effects - Bone Fracture (Vertebral Fracture)

Abstract

As future HEMI device designs may consider different waveforms and durations, it is useful to consider the effects of prolonged muscle excitation and contraction on the spine. Prior porcine testing revealed that spinal fractures frequently occurred when the animals were subjected to prolonged muscle contraction [1]. This leads us to consider if the human spine is also susceptible to fracture when the trunk musculature is activated under specific HEMI waveforms for prolonged durations. The main goal in this report is to estimate the chance of vertebral fracture risk due to prolonged electro-muscular excitation. To accomplish this, we compare the likelihood of vertebral fracture due to HEMI induced muscle contraction in porcine versus human conditions. We also investigate whether individual body types, or other risk factors, may influence vertebral fracture risk and help identify vulnerable populations.
