Summary

The previous pilot study showed that two weeks of intensive expiratory muscle strength training (EMST) with SpiroGym was sufficient to significantly improve voluntary peak cough flow (PCF). The improvement was quantitatively comparable to that reported in other intensive EMST studies of longer duration. To explain this rapid improvement, we considered the potential contribution of SpiroGym's visual feedback. We assumed that real-time visual feedback increased training effort compared with conventional EMST performed without immediate feedback.

The aim of this study is to evaluate the effect of visual feedback provided by the SpiroGym mobile application on performance during expiratory muscle strength training in patients with Parkinson's disease.

Interventions

DEVICE

EMST with SpiroGym app

Participants will perform expiratory muscle training using an Expiratory Muscle Trainer (EMST150; Aspire Products, LLC, United States). Participants will be instructed to perform five sets of five forceful expirations coupled with the SpiroGym app. Video feedback via the SpiroGym app: During correct performance of the expiratory manoeuvre with the handheld device, the exhalation valve opens and the resulting airflow increases the sound level detected by the microphone. Simultaneously, the application provides real-time visual feedback on the mobile phone screen as a curve depicting the current sound level. The patient's task is to keep the curve within the training zone, defined by two lines corresponding to the lower and upper thresholds.

DEVICE

EMST without SpiroGym app

Participants will perform expiratory muscle training using an Expiratory Muscle Trainer (EMST150; Aspire Products, LLC, United States). Participants will be instructed to perform five sets of five forceful expirations without the SpiroGym app.
