Description

This study examines the role of the direction of a fall on neuromuscular response. Electromyography sensors were positioned on the erector spinae of twenty subjects. Falls, simulating slips, occurred in the anterior, posterior, and medial-lateral directions. The average activation curves for the four different fall directions displayed different characteristics. Observations were supported by principal component analysis (PCA). PCA coefficients related all fall directions to a single reflex-like response. Analysis of variance on the coefficients demonstrated that anterior falls had a significantly (p
