Recovery Of Force Output And Electromyography From Trunk Muscles After Cyclic Passive Loading.

Abstract

Continuous loading of the low back tissues results in modified neuromuscular and kinetic output during trunk extension efforts. It is believed that the viscoelastic behavior of these low back tissues is modified, but the ramifications of these loading schemes needs further study for longer durations. The purpose of this research project was to observe force output and muscle activation pattern changes during trunk extension efforts before and up to 60 minutes after
