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.

Plain Language Summary

Simplified for easier understanding

This study is testing whether visual feedback from a mobile app (SpiroGym) can improve breathing and voice symptoms in people with Parkinson's disease by helping them learn to breathe and vocalise more effectively. **You may be eligible if...** - You have been diagnosed with Parkinson's disease - Your dopamine (Parkinson's) medication dose has been stable for at least one month **You may NOT be eligible if...** - You have another neurological disorder in addition to Parkinson's disease - You have significant memory or thinking difficulties - You have a major psychiatric condition - You have had cancer of the head or neck, or previous neck surgery - You become unwell during the study period Talk to your doctor to see if this trial is right for you.

Interventions

DEVICEEMST 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.
