“…An ankle-foot orthosis (AFO) is often worn on the paretic limb to improve walking performance in poststroke rehabilitation. 16 AFOs can increase the load on the paretic limb, with increasing the vGRF in the paretic stance phase, 16 which would help to move the CoM upward during the double-limb support phase. Especially, an AFO with an oil damper (AFO-OD; Gait Solution Design, Kawamura Gishi, Japan) provides functional movement by generating resistive ankle plantarflexion moment during the paretic loading response phase (the details are presented in Figure 1).…”

Background: An ankle-foot orthosis with an oil damper (AFO-OD) may improve kinetics and kinematics for efficient walking after stroke. Yet it is unknown whether hemiplegic walking behaves like "inverted-pendulum" gait and how it is modulated by using AFO-ODs for efficiency.Objectives: This study examined whether the use of AFO-ODs improves the kinetics of total vertical ground reaction force (vGRF) and kinematics of vertical pelvic displacement (vPD) in different walking phases, and gait speed following stroke. Also, the relationship between those gait parameters was examined to assess efficient walking.Study design: Observational study within subject. Methods: Eight participants with hemiplegia walked at self-selected speed without and with AFO-ODs over the walkway and gait speed was measured. Force plates were used to measure total vGRF during the double-limb support phase with the paretic leading limb and with the paretic trailing limb (DSPT). The vPD in the paretic and nonparetic stance phases was measured by a threedimensional motion analysis system. Results: Without AFO-ODs, reduced total vGRF during DSPT was related to greater vPD in the subsequent nonparetic stance. Using AFO-ODs significantly increased gait speed and total vGRF during double-limb support phase with the paretic leading limb and during DSPT, which were significantly correlated. Vertical pelvic displacement in the nonparetic stance was higher than the paretic stance in both conditions. Conclusions: Decreased total vGRF during DSPT was compensated by excessive vPD in the nonparetic stance phase without AFO-ODs, indicating inefficient walking. However, the use of AFO-ODs improved the kinetic energy of total vGRF during the doublelimb support phase, contributing to efficient walking. Clinical relevance statement: The AFO-ODs can be used to improve kinetic energy and to modulate functions in the weight transition during the double-limb support phase, with faster walking speed. Thus, AFO-ODs can be considered to be therapeutic AFOs to acquire efficient walking performance in poststroke rehabilitation.

“…On the other hand, the main objective of robotics-based rehabilitation systems in stroke therapy is to provide assistance in restoring impaired limb movements. These systems mainly include orthoses, exoskeletons, and other robotics units that allow the rehabilitation of upper and lower limbs, depending on the stroke severity [28][29][30][31][32][33][34][35][36][37][38][39]. An additional advantage of robotics systems includes the ability to measure the dynamic and kinematic parameters of the subject's motion during the therapy.…”

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.
