the effect of high frequency rtms on advancing parkinson's disease with dysphagia

Conditions: Advanced Parkinson's With Dysphagia

Summary: this study aims to assess the therapeutic role of rtms on parkinson's patients with dysphagia. thirty pd patients with dysphagia using uk bank criteria for pd will recruited from outpatient clinic in assuit university. all patients were admitted at neuropsychiatric department, assiut university hospital/ assiut, egypt. each patient fulfilled the inclusion criteria as spontaneous swallows should be identified clearly when patients cannot perform voluntary swallows using clinical examination test. the patients will be allocated randomly into two groups one of which will receive real sessions of high frequency rtms (25 hz), with intensity of 80% of resting motor threshold detected from the hand motor area, with total 2000 pulses for each hemisphere for 10 consecutive sessions totally over period of 10 days with repeated booster session every month during the period of follow up among three months. the other will receive sham sessions. all subjects will be followed up by selected clinical rating scales at different intervals pre session, post 10 sessions, and after one, two and three months.

this study aims to assess the therapeutic role of repetitive transcranial magnetic (rtms) on parkinson's patients with dysphagia. thirty pd patients with dysphagia using uk bank criteria for pd will recruited from outpatient clinic in assuit university. all patients were admitted at, neuropsychiatric department, assiut university hospital/ assiut, egypt. each patient fulfilled the inclusion criteria as spontaneous swallows should be identified clearly when patients cannot perform voluntary swallows using clinical examination test. the patients will be allocated randomly into two groups using closed envelops one of which will receive real sessions of high frequency rtms (25 hz), with intensity of 80% of resting motor threshold detected from the hand motor area, with total 2000 pulses for each hemisphere for 10 consecutive sessions totally over period of 10 days with repeated booster session every month during the period of follow up among three months. the other will receive sham sessions. all subjects after receiving the rtms will be followed up by selected clinical rating scales at different intervals pre session, post 10 sessions, after one, two and three months.
