简要总结
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.
详细描述
The study will be conducted using a prospective crossover design. Patients with Parkinson's disease will complete two EMST sessions, each at 75% of maximum expiratory pressure (MEP), separated by a two-week interval. One EMST session will include feedback via the SpiroGym mobile application, while the other will be performed without feedback. The order of these conditions will be randomly assigned.
Primary hypothesis
- Visual feedback provided by the SpiroGym application during expiratory training will result in greater muscle activation, as measured by surface electromyography (sEMG), compared with training without visual feedback.
Secondary hypotheses 2. Visual feedback during expiratory training will lead to greater expiratory performance, reflected by higher noise intensity recorded by the SpiroGym application, than training without visual feedback. 3. Participants will report lower perceived difficulty and higher motivation to perform expiratory training exercises when visual feedback is provided than when it is absent.

结局指标
主要结局
Surphace elektromyography (sEMG) measurement of abdominal muscle (m. obliquus internus abdominis).
时间窗: Baseline, week 2
Wireless sEMG electrodes will be placed on the clean skin of the abdominal muscle (m. obliquus internus abdominis). A reference voluntary contraction (RVC) will be used to normalize the sEMG data. sEMG of the abdominal muscle (m. obliquus internus abdominis) during two conditions (EMST with SpiroGym and EMST without SpiroGym) will be compared.
次要结局
- SpiroGym Sound Intenzity (SSI) measurement(Baseline, week 2)
- SpiroGym Sound Intenzity (SSI) measurement(Baseline, week 2)
- Surphace elektromyography (sEMG) measurement of suprahyoid muscle complex and abdominal muscles (m. rectus abdominis and m. obliquus externus abdominis).(Baseline, week 2)
- Participant's Feedback questionnaire(week 2)
