The use of rhythmic auditory stimulation (RAS) has been proven useful in the management of gait disturbances induced by Parkinson's disease (PD). Typically, the stimuli used to provide RAS consist of metronome or music-based sounds, which are not related with the auditory experience of walking. Based on previous laboratory research, it is hypothesized that the use of ecological sounds deriving from biological motion (i.e., footstep sounds) could have a greater impact compared to artificial sounds (i.e., metronome sounds), within a rehabilitation program. In a double-blind experiment, it was investigated the effects of 5 weeks of supervised rehabilitation integrated with RAS. Thirty-two individuals affected by PD (age 68.2 ± 10.5, Hoehn and Yahr 1,5-3) were randomly assigned to one of the two conditions (artificial vs. ecological sounds). Spatio-temporal parameters of gait and clinical variables were assessed before the rehabilitation period, at its end, and after a 3-month follow-up. The results revealed that the rehabilitation program integrated with RAS had positive effects on the majority of objective and subjective measures, independently of the type of sound. However, when the two groups were examined separately, the patients assigned to the ecological RAS condition were the only who improved both in terms of cadence and gait speed. Overall, the hypothesized greater effect of the ecological sounds compared to artificial sounds was only partially supported by data.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Artificial Sounds | Experimental | Participants were provided headphones and a portable MP3 device which played a metronome tick at specified rhythm calculated as follows: a) if a patient's cadence was below the normality, the BPM of the stimulus was set at a value of 10% higher than one's own cadence; b) if a patient's cadence was below, but close to normality (less than 10% difference), the BPM of the stimulus was set at normality values; c) if a patient's cadence was above the normality, the BPM of the stimulus was set at a value equal to one's own cadence. Participants performed daily 30 minutes of walking assisted by the rhythmic acoustic stimuli. |

| Ecological Sounds | Experimental | Participants were provided headphones and a portable MP3 device which played an ecological rhythmic sound obtained by actual footsteps of human at specified rhythm calculated as follows: a) if a patient's cadence was below the normality, the BPM of the stimulus was set at a value of 10% higher than one's own cadence; b) if a patient's cadence was below, but close to normality (less than 10% difference), the BPM of the stimulus was set at normality values; c) if a patient's cadence was above the normality, the BPM of the stimulus was set at a value equal to one's own cadence. Participants performed daily 30 minutes of walking assisted by the rhythmic acoustic stimuli. |

Participants were randomly assigned to one of the two groups (artificial or ecological RAS) and were evaluated in three moments: before the rehabilitative treatment (T0), at the end of the 5 week rehabilitative treatment (T5), and 3 months after the end of the treatment, namely 17 weeks after the first assessment (T17).
