Key information

About this study

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.

  • Diagnostis of OH
  • able to perform an ambulatory physiotherapy at Aachen University Hospital.

Treatment and study plan

Physiotherapy

Other

Ambulatory leg-muscle oriented physiotherapy (2 x 45 minutes per week for at least 8 weeks) at Aachen University Hospital. Daily protocol of leg muscle training, exercises, sufficient fluid intake of 2liter/day, pressure stockings.

Primary outcomes

  1. Blood Pressure in mmHg

    Time frame: 10months

    Systolic postural blood pressure drop in the interventional Group (Long_Physiotherapy) less than 10mmHg (5-15mmHg) compared to Short_Physiotherapy

Secondary outcomes

  1. Attention in TAP

    Time frame: 10months

    Attention Tasks (TAP) ≥ 20% Change in Long_Physiotherapy

  2. Orthostatic symptoms (Winkler Scale)

    Time frame: 10months

    ≥ 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

  3. daytime sleepiness

    Time frame: 10months

    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
