Stroke aerobic exercise daily functioning rehabilitation
Brief summary
This study aims to investigate the effect of aerobic exercise on the aerobic capacity, the daily functioning, post-stroke fatigue , depression and cardiovascular risk factors in stroke patients.
Detailed description
People with neurologic impairments after stroke often show decreased aerobic exercise capacity. The etiologies of which are assigned to physiologic changes in paretic muscle, gait deficits and disability-related deconditioning. This declares that stroke patients live an inactive lifestyle and therefore stay cardiovascular risk patients. The usefulness of aerobic training on aerobic capacity is recently been proved in clinical stroke research. However, no study can shown the long-term effect of aerobic exercises. Also the effect of aerobic exercises on daily functioning, fatigue and depression in stroke needs to be established.
Interventions
BEHAVIORALAerobic exercise group
The patients continue their regular therapy in the rehabilitation center. They participate in a 12-week programme of aerobic training 30 minutes/session, using a leg cycle bike. Patients will be trained three times a week. The heartrate will vary from 50 tot 75% of their predicted heart rate. Each patient will be provided with an progressive exercise prescription based on 50-75% of their predicted maximum heartrate. Throughout the training sessions the heart rate will be monitored continuously with a polar pulse rate. Within these 12 week exercise programme four information sessions will be offered to patients and relatives about risk factors of stroke, usefulness of an active lifestyle and healthy eating.
BEHAVIORALControl group
The patients continue their regular therapy in the rehabilitation center. They participate in a 12-week programme of passive mobilisation of the hemiplegic knee, using a continuous passive motion device. Patients will be trained three times a week, 30 minutes/session.
BEHAVIORALFollow-up first aerobic exercise group
The experimental aerobic exercise will be divided in two groups at random after the 12 weeks aerobic exercise programme. The first group will get feedback on how to train further their aerobic capacity within the following 9 months. The second group will not undergo the feedback programme.
BEHAVIORALFollow-up control group
No intervention will be offered in a period of 9 months after the passive mobilisation programme
BEHAVIORALFollow-up second aerobic exercise group
The experimental aerobic exercise will be divided in two groups at random after the 12 weeks aerobic exercise programme. The second group will not undergo the feedback programme. This group will be measured but not treated with an intervention programme
