Objective.Stroke is one of the most common neural disorders, which causes physical disabilities and motor impairments among its survivors. Several technologies have been developed for providing stroke rehabilitation and to assist the survivors in performing their daily life activities. Currently, the use of flexible technology (FT) for stroke rehabilitation systems is on a rise that allows the development of more compact and lightweight wearable systems, which stroke survivors can easily use for long-term activities.Approach.For stroke applications, FT mainly includes the 'flexible/stretchable electronics', 'e-textile (electronic textile)' and 'soft robotics'. Thus, a thorough literature review has been performed to report the practical implementation of FT for post-stroke application.Main results.In this review, the highlights of the advancement of FT in stroke rehabilitation systems are dealt with. Such systems mainly involve the 'biosignal acquisition unit', 'rehabilitation devices' and 'assistive systems'. In terms of biosignals acquisition, electroencephalography and electromyography are comprehensively described. For rehabilitation/assistive systems, the application of functional electrical stimulation and robotics units (exoskeleton, orthosis, etc) have been explained.Significance.This is the first review article that compiles the different studies regarding FT based post-stroke systems. Furthermore, the technological advantages, limitations, and possible future implications are also discussed to help improve and advance the flexible systems for the betterment of the stroke community.
