Kinematic synergies in over-ground slip recovery outcomes: Distinct strategies or a single strategy?

ABSTRACT:

Background

After experiencing an unexpected slip perturbation, individuals' behavioral performance can be classified into three categories: recovery, feet-forward fall, and split fall. Researchers are uncertain whether these differences in slip outcomes are due to distinct strategies or part of a single strategy.

Research question

Whether older adults with different behavioral outcomes during their novel slip have different kinematic synergies?

Methods

The kinematic synergies were extracted from segment angles in 87 participants using principal component analysis (PCA). The first two principal components (PC1 and PC2) in pre-slip, early-reactive, and late-reactive phases were compared across different slip outcomes.

Results

Results showed that the kinematic syn
