Pathological forward trunk flexion (FTF) is a drug-refractory complication in patients with PD leading to imbalance, pain and fall-related injuries. Deep abdominal muscle training is a key rehabilitation strategy for FTF, as muscles like the transversus abdominis and multifidus are crucial for lumbar stabilization. This training has been shown to improve body position and lumbar proprioception.\n\nAbdominal muscles are also responsible for forced expiration. Expiratory muscle strength training (EMST) utilizing forced expiration through expiratory trainer has emerged as a beneficial intervention in the non-pharmacological management of PD, positively impacting clinical aspects such as dysphagia, dystussia, hypokinetic dysarthria, and drooling. EMG study showed large abdominal muscles activity, particularly the transversus abdominis and internus obliquus abdominis during EMST. Therefore, EMST might also be effective in improving lumbar stabilization.\n\nGiven the established role of abdominal muscles in trunk stabilization, it is plausible that activation of deep abdominal muscles during EMST with the right level of resistance might improve FTF in PD patients. No studies have yet examined the effect of EMST on posture in PD.\n\nThe primary aim of this study will be to evaluate the effect of EMST on forward trunk flexion in patients with Parkinson's disease.\n\nThe secondary aim will be to assess the potential duration of the EMST effect on postural abnormalities and its impact on patient stability.",[63],"Parkinson Disease",[63,9,65],"Forward Trunk Flexion","NOT_YET_RECRUITING","2025-04-30",{"date":69,"type":70},"2025-05-09","ACTUAL",{"date":72,"type":57},"2025-08",{"date":74,"type":57},"2026-01",{"name":5,"class":6},1]
