Neurorehabilitation for Parkinson's disease: Future perspectives for behavioural adaptation

Parkinson's disease is a common neurodegenerative disorder, resulting in both motor and non-motor symptoms that significantly reduce quality of life. Treatment consists of both pharmaceutical and non-pharmaceutical treatment approaches. Neurorehabilitation is an important non-pharmaceutical treatment approach, and a prime component of this is formed by the training of behavioural adaptations that can assist patients to cope better with their motor and non-motor symptoms. Optimal delivery of neurorehabilitation requires a tailor-made, personalized approach. In this review we discuss the great potential for growth in the field of neurorehabilitation. Specifically, we will focus on four relatively new developments: visual rehabilitation (because Parkinson patients are very dependent on optimal vision); cueing delivered by wearable devices (allowing for objective, continuous, and quantitative detection of mobility problems, such that cueing can be delivered effectively in an on-demand manner - i.e., with external cues being delivered only at a time when they are needed most); exergaming (to promote compliance with exercise programs); and telemedicine (allowing for delivery of expert rehabilitation advice to the patient's own home). Evidence in these new fields is growing, based on good clinical trials, fuelling hope that state-of-the-art neurorehabilitation can make a real impact on improving the quality of life of patients affected by Parkinson's disease.
