Overview
Brief Summary
The purpose of this randomised and controlled study is to investigate the effects of walking training combined with respiratory muscle training on pulmonary function, respiratory muscle strength, and functional exercise capacity.
Detailed Description
Although respiratory dysfunction has been recognized as a cause of morbidity and mortality in patients with Parkinson's disease (PD), most of the patients were not aware of their respiratory problems due to restriction in their activities. Respiratory dysfunction in patients with PD has not been well characterized. However, there are many studies showing restrictive or obstructive type respiratory disorders and decreased respiratory muscle strength in the literature. Ineffective cough due to decreased respiratory muscle strength may cause to secretion retention and secondary infections in PD patients who have severe symptoms. Therefore, the assessment and rehabilitation of these respiratory problems is important in PD patients treatment. There are studies in the literature showing that respiratory muscle training is effective in PD. Walking difficulty is seen as a common problem in PD. Typically, walking is slow despite adequate Levodopa therapy. It is known that exercise capacity may be affected by respiratory impairment, walking difficulties and personal exercise habits in patients with PD. Respiratory and walking problems lead to limitation of physical activity in PD, which leads to a decrease in exercise capacity. In a recently published article reported that walking is a good example of exercise. Although walking training is important for PD patients, there is no studies what happens to pulmonary function and functional exercise capacity when walking training is combined with respiratory muscle training in patients with Parkinson's disease. Therefore, this study planned to investigate the effects of walking and respiratory muscle training on pulmonary function and functional exercise capacity in PD.

Outcomes
Primary Outcomes
Maximal Inspiratory mouth pressure (PImax) and Maximal Expiratory mouth pressure (PEmax)
Time Frame: Change from baseline maximal inspiratory mouth pressure and maximal expiratory pressure at 8 weeks
Maximum inspiratory pressure (PImax) is the classic volitional test for inspiratory muscle strength. It is measured as the highest mouth pressure (cmH2O) sustained for 1 s during a maximum inspiratory effort against a quasi occlusion. Assessment is carried out according to the Black and Hyatt technique. Maximum expiratory pressure (PEmax) is the classic volitional test for expiratory muscle strength. It is measured as the highest mouth pressure (cmH2O) sustained for 1 s during a maximum expiratory effort against a quasi occlusion. Assessment is carried out according to the Black and Hyatt technique.
Functional Exercise Capacity
Time Frame: Change from baseline functional exercise capacity at week 8
Functional exercise capacity was measured with the 6 Minute Walk Test (6MWT) according to the American Thoracic Society (ATS) guidelines. The 6 minutes walking distance (6MWD) was recorded in meters.
Secondary Outcomes
- Spirometric measurements(Baseline and week 8)
- Unified Parkinson's Disease Rating Scale - motor examination(Baseline and week 8)
