A comparison of voice amplifiers and personal communication systems in individuals with hypophonia: An exploration of communicative participation
(2022)
Abstract
Hypophonia is one of the most prevalent speech impairments in hypokinetic dysarthria. Unfortunately, behavioral interventions for hypophonia often fail to generalize beyond the clinic. An alternative approach to management is the use of speech amplification devices. This study evaluated how 17 individuals with hypophonia (HP) and their primary communication partners (PCPs) rated communicative participation across three, one-week device trial periods at home. Amplification devices included: a wired belt pack amplifier, wireless stationary amplifier, and personal FM system. Patient-reported outcome measures included the CES, VAPP and PIADS. Results indicated HPs rated participation higher following device use in comparison no device. Further, HP and PCPs rated these measures similarly suggesting PCPs can be used reliably as proxies. Finally, the FM system produced the overall highest VAPP ratings and second highest CES ratings. This study will serve to inform evidence-based prescription of speech amplification devices from a multi-dimensional approach for individuals with hypophonia.
