Symmetry of VEMP Responses across Swimmers and Non-swimmers

The purpose of the current study was to investigate if swimmers show any greater asymmetry (right versus left) related to the nature of their strength and/ or flexibility training on amplitudes of Cervical Vestibular Evoked Myogenic Potentials than non-swimmers. A total of sixteen subjects (eight swimmers and eight non-swimmers) participated in the study. Results of our study showed no significant differences in amplitudes between swimmers and non-swimmers even when corrected for effects of tonic neck muscle activity. Hence the clinical interpretation of these potentials does not appear to be confounded by swimming-related asymmetries.
