Stroke Clinical Trial

Official title:
Does Moderate Intensity Aerobic Training Influence Serum Levels of BDNF in Sub-acute and Chronic Stroke Patients and Consequently Increase the Efficacy of Upper-limb Rehabilitation? A Study Protocol for a Randomized Control Trial With an Embedded Health Economic Evaluation.

Status Completed

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. . ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
