Tolerance of the VocaLog™ Vocal Monitor by Healthy Persons and Individuals With Parkinson Disease

The VocaLog™ offers a method to monitor vocal loudness during everyday activities for several consecutive days. The device was well tolerated by participants from both groups. IWPD reported greater discomfort than controls, possibly reflecting altered sensory perceptions associated with PD. The current data offer some reassurance that this VM can be tolerated by both healthy persons and those with PD for clinical and research purposes.
