Clinical Trial Summary

Study on orthostatic Hypotension in Parkinson's disease

Description:

Orthostatic hypotension (OH) in Parkinson's disease (PD) may not only be related to dizziness or light headedness but to deficits in attention, visual, and verbal memory. Would a successful treatment of OH which includes physiotherapy significantly improve OH and these cognitive deficits? By means of a randomized cross-over trial, we want to measure and compare the effects of OH therapy on orthostatic tolerance, as well as on attention, visuo-spatial working memory, and verbal memory in patients with PD. If confirmed, therapy of orthostatic hypotension would provide a sound and simple approach to improve those cognitive deficits originating from orthostatic hypotension.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Blood Pressure in mmHg	Systolic postural blood pressure drop in the interventional Group (Long_Physiotherapy) less than 10mmHg (5-15mmHg) compared to Short_Physiotherapy	10months
Secondary	Attention in TAP	Attention Tasks (TAP) = 20% Change in Long_Physiotherapy	10months
Secondary	Orthostatic symptoms (Winkler Scale)	= 2 points change in Winkler Scale (Sum Score) in Long_Physiotherapy; 10 symptoms must be rated concerning their frequency from 0= never to 4= more than once a day. Sum score from minimum 0 points (no symptoms) to maximum 40 points (all symptoms more than once daily) is interpreted	10months
Secondary	daytime sleepiness	Epworth Sleepiness Scale = 20% Change of Sum Score in Long_Physiotherapy. Sum Score can range from minimum = 0 Points to Maximum = 24points. More points indicate more symptoms. Cut off for daytime sleepiness are10 points	10months
