      abstract     = {It is known that music influences gait parameters in
                      Parkinson's disease (PD). However, it remains unclear
                      whether this effect is merely due to temporal aspects of
                      music (rhythm and tempo) or other musical parameters.To
                      examine the influence of pleasant and unpleasant music on
                      spatiotemporal gait parameters in PD, while controlling for
                      rhythmic aspects of the musical signal.We measured
                      spatiotemporal gait parameters of 18 patients suffering from
                      mild PD $(50\%men,$ mean±SD age of 64±6 years; mean
                      disease duration of 6±5 years; mean Unified PD Rating scale
                      [UPDRS] motor score of 15±7) who listened to eight
                      different pieces of music. Music pieces varied in harmonic
                      consonance/dissonance to create the experience of
                      pleasant/unpleasant feelings. To measure gait parameters, we
                      used an established analysis of spatiotemporal gait, which
                      consists of a walkway containing pressure-receptive sensors
                      (GAITRite®). Repeated measures analyses of variance were
                      used to evaluate effects of auditory stimuli. In addition,
                      linear regression was used to evaluate effects of valence on
                      gait.Sensory dissonance modulated spatiotemporal and spatial
                      gait parameters, namely velocity and stride length, while
                      temporal gait parameters (cadence, swing duration) were not
                      affected. In contrast, valence in music as perceived by
                      patients was not associated with gait parameters. Motor and
                      musical abilities did not relevantly influence the
                      modulation of gait by auditory stimuli.Our observations
                      suggest that dissonant music negatively affects particularly
                      spatial gait parameters in PD by yet unknown mechanisms, but
                      putatively through increased cognitive interference reducing
                      attention in auditory cueing.},
