Reward During Arm Training Improves Impairment and Activity After Stroke: A Randomized Controlled Trial.

ABSTRACT:

Background

Learning and learning-related neuroplasticity in motor cortex are potential mechanisms mediating recovery of movement abilities after stroke. These mechanisms depend on dopaminergic projections from midbrain that may encode reward information. Likewise, therapist experience confirms the role of feedback/reward for training efficacy after stroke.

Objective

To test the hypothesis that rehabilitative training can be enhanced by adding performance feedback and monetary rewards.

Methods

This multicentric, assessor-blinded, randomized controlled trial used the ArmeoSenso virtual reality rehabilitation system to train 37 first-ever subacute stroke patients in arm-reaching to moving targets. The rewarded group (n = 19) trained with performance feedback (gameplay) a
