Intra- and inter-individual variability of vibration-induced postural reactions in healthy adults

The present work characterized the variability of postural reactions induced by mechanical vibration of ankle tendons. Posturography measures were obtained with a forceplate on thirty healthy adults. Overall, results denoted a high level of measurement error (intra-subject variability), but good to excellent intraclass correlation coefficients (i.e. relatively unchanging results between individuals with repeated testing). Future perspectives for research and clinical applications of vibration-induced postural reactions (Vib-PR) are discussed.
