Official study title

Effect of the SpiroGym App on Voluntary Cough Strength in Parkinson's Disease

Short title used by the registry

SpiroGym App-Aided Cough Rehabilitation

Original description

The pilot study by Srp et al. (2021) proved that the SpiroGym app was feasible for supporting expiratory muscle strength training (EMST) in Parkinson's disease (PD) patients. Two weeks of intensive EMST coupled with SpiroGym were sufficient to significantly improve the participants' voluntary peak cough flow (PCF). The improvement was quantitatively comparable to the results of other intensive EMST studies with longer durations. When interpreting such rapid improvement, the impact of SpiroGym's visual feedback was considered. It was assumed that visual feedback increased training effort compared to regular training without immediate control. However, comparative studies were required to verify the possible additional effects of visual feedback on voluntary PCF compared to EMST without feedback.

Further description from the registry

Goal: To explore the visual feedback effect of the SpiroGym app in EMST on voluntary peak cough Hypothesis 1: Change in voluntary peak cough flow will be higher in the experimental group than in the active control group after 8weeks and 24 weeks of EMST. Study Design: A double-blind, randomized controlled trial

Conditions reported: Parkinson Disease; Voluntary Peak Cough Strength; mHealth
