“…We successively used three different trikes in preparation for the race: BerkelBike Pro (BerkelBike B.V., Netherlands), 12 Rehabike (Hasomed GmbH, Germany), 13 and Carbontrikes Race SL (Carbontrikes, Sweden). 14 The first two were commercially available FES trikes; the third one, which we named “TetraTrike” was a custom made mono-bloc carbon recumbent trike that we equipped with in-house FES equipment.…”

Whether it is from the patient’s or the physical therapist’s point of view, FES cycling can be considered either as a recreational activity, or an engaging rehabilitation tool. In both cases, it keeps patients with lower-limb paralysis motivated to sustain a regular physical activity. Thus, it is not surprising that it was selected as one of the six disciplines of the first Cybathlon competition held on October 8, 2016. However, many unresolved issues prevent FES cycling from being an activity practiced outdoors on a daily basis; such as, low power production, rapid muscle fatigue, precise electrode positioning, lack of systematic procedures to determine stimulation patterns, and the difficulty of transferring disabled riders from their wheelchair to the tricycle. This article documents the challenges we faced during preparation for the Cybathlon 2016 FES cycling race, and provides results obtained during different phases of the process. A particular specificity of our team was that, unlike most other teams where pilots were mainly paraplegic, both the primary and backup pilots for team ENS de Lyon are C6/C7 tetraplegics, with neither voluntary control of their abdominal muscles nor hand grip, and only partial use of their arms.

“…The importance of the FES treatment is that cortical activation could be facilitated by forcing the patients to practice with impaired extremities, which patients do not tend to use due to difficulties [29]. Moreover, the psychological benefits of utilizing FES rehabilitation, such as increasing self-esteem and reducing depression [30]. Therefore, studies have been conducted with FES for the motor function restoration of stroke and TBI patients [21,31].…”

Functional Electrical Stimulation Controlled by Motor Imagery Brain-Computer Interface for Rehabilitation

Sensorimotor rhythm (SMR)-based brain–computer interface (BCI) controlled Functional Electrical Stimulation (FES) has gained importance in recent years for the rehabilitation of motor deficits. However, there still remain many research questions to be addressed, such as unstructured Motor Imagery (MI) training procedures; a lack of methods to classify different MI tasks in a single hand, such as grasping and opening; and difficulty in decoding voluntary MI-evoked SMRs compared to FES-driven passive-movement-evoked SMRs. To address these issues, a study that is composed of two phases was conducted to develop and validate an SMR-based BCI-FES system with 2-class MI tasks in a single hand (Phase 1), and investigate the feasibility of the system with stroke and traumatic brain injury (TBI) patients (Phase 2). The results of Phase 1 showed that the accuracy of classifying 2-class MIs (approximately 71.25%) was significantly higher than the true chance level, while that of distinguishing voluntary and passive SMRs was not. In Phase 2, where the patients performed goal-oriented tasks in a semi-asynchronous mode, the effects of the FES existence type and adaptive learning on task performance were evaluated. The results showed that adaptive learning significantly increased the accuracy, and the accuracy after applying adaptive learning under the No-FES condition (61.9%) was significantly higher than the true chance level. The outcomes of the present research would provide insight into SMR-based BCI-controlled FES systems that can connect those with motor disabilities (e.g., stroke and TBI patients) to other people by greatly improving their quality of life. Recommendations for future work with a larger sample size and kinesthetic MI were also presented.

“…In electrical stimulation usually electrical signals of certain characteristics are used (usually of low amplitudes) to help to revert or reduce abnormalities in utterances or responses of the human body parts due to the nervous system failure as a result of diseases, trauma or complications (such as spinal cord injury, head injury, stroke and other disorders) which are usually controlled by the central nervous system (CNS) (Arantes et al, 2007;Braz, Russold, & Davis, 2009;Chen et al, 2014;Durfee, 2006;Ethier, Oby, Bauman, & Miller, 2012;Jezernik et al, 2002;Kern et al, 2010;Lee et al, 2013;Papachristos, 2014;Tan et al, 2014). The function reversal/revival of the affected body part is achieved by systematically applying the desirable electrical signals its muscles/nerves.…”

“…The function reversal/revival of the affected body part is achieved by systematically applying the desirable electrical signals its muscles/nerves. The term Functional Electrical Stimulation (FES) usually refers to the use of electrical stimulation for movement restoration (Arantes et al, 2007;Durfee, 2006;Papachristos, 2014;Tan et al, 2014). Figure 1 is a brief demonstration of how to use electrical stimulation is accomplished for the restoration of some functions.…”

Functional Electrical Stimulation (FES) can be used to revive movement functions of the human body to a certain degree which was lost due to occurrences of the nervous system disorders resulting from accidents or diseases. It can also be employed for gait rehabilitation as well as therapy. Control systems could be employed to improve on the FES-induced motion, and the closed-loop was targeted due to its advantages. Based on the papers reviewed, studies have shown that the linear control schemes are popular for movement restoration in the lower limb, but mostly for continuous standing contributing to mainly the stance phase. Therefore, a myriad of limitations was observed which include: the need for using improved sensors, re-tuning for every subject, tests conducted using patient with more straightforward ailments, complexity in implementation and most importantly is the issue of stability. The swing phase of gait movement and the full walking motion have more complex dynamics and coupled with the nature of the plant (human with nervous system disorder and the neuromuscular structure) could render the linear control method obsolete or unsuitable. Hence, there is a need to investigate other techniques such as the nonlinear and intelligent control methods.
