Clinical Trial Summary

The aim of this study is to evaluate the influence on three different training modalities on the blood concentration levels of a growth factor called Brain Derived Neurotrophic Factor (BDNF) and on the recovery of arm function following in sub-acute and chronic stroke survivors. The training modalities are 1. moderate intensity aerobic training on a bike ergonometer followed by robotic or sensor-based upper-limb training, 2. non-aerobic circuit training followed by robotic or sensor-based upper-limb training 3. circuit training alone.


Clinical Trial Description

Background and Rationale:Brain-derived neurotrophic factor (BDNF) belongs to a group of neurotrophins which influence neuroplasticity by increasing long-term potentiation and axonal and dendritic growth. Levels of serum BDNF are increased following moderate intensity aerobic exercise (MAE) in animal and healthy subjects. The influence of MAE on BDNF following stroke and the resultant efficacy of motor training in this environment remains unclear.

Objective(s):To investigate the influence of MAE on acute and chronic levels of serum BDNF in sub-acute and chronic stroke patients, the efficacy of robotic upper limb or sensor based motor task training in this environment and consequent effect on functional arm recovery compared to the same upper limb training following non-aerobic training circuit training, or non-aerobic circuit training alone To evaluate the cost-effectiveness of the interventions. Study Interventions: Group 1: moderate intensity AE 40 minutes, 3 times weekly followed after 20 minutes break by 40 minutes robotic or sensor-based upper-limb Training. Group2: non-aerobic gait and balance circuit training 40 mins 3 times weekly followed after 20 minutes break by 40 minutes robotic or sensor-based upper-limb training, group 3: 40 minutes non-aerobic gait and balance circuit training.In total 45 participants will be enrolled - 15 in each group.Study Duration:3 monthly Intervention period per intervention group, with a 3 month and 6 month follow-up. . ;
