A systematic review of perturbation-based balance training on reducing fall risk among individuals with stroke
The existing evidence does not conclusively support the reduction in falls and improvements in fall risk factors resulting from perturbation-based balance training among people with stroke. Such an inconsistent finding could be due to the small sample sizes and variations in perturbation-based balance training protocols across studies. More high-quality studies are needed to further determine the effects of perturbation-based balance training on reducing fall risk in people with stroke.

Control of center of mass during gait of stroke patients: Statistical parametric mapping analysis
The statistical parametric mapping approach showed to be suitable for determining gait changes in post-stroke individuals, irrespective of their motor recovery stage.

Time profile of kinematic synergies of stroke gait.
Despite the sensory-motor deficits and the atypical kinematic behavior, stroke patients can produce joint covariations to control the center of mass trajectory in the forward progression plane, but the modulation of the synergy is impaired, reflecting altered adjustments, especially in the paretic limb of subjects with worse levels of motor recovery.

Effects of a wearable sensor –based virtual reality game on upper-extremity function in patients with stroke
Interventions based on the PABLO virtual reality system improved upper extremity hand function, shoulder and elbow movements, and elicited a higher degree of enjoyment from study participants, than did traditional treatment.Trials registration: The study protocol was registered at Clinical Trials.gov PRS (No.NCT04296032).

Exploration of arm weight effects on hemiparetic stroke participants' gait performance
This study's exploratory results demonstrate arm weight's potential for improving higher-functioning stroke survivors' gait performance. Arm weight addition merits further investigation as a possible rehabilitation intervention in the stroke population.

Instantaneous effect of real-time avatar visual feedback on interlimb coordination during walking post-stroke
Improvements in gait symmetry may be explained by changes in interlimb coordination. Current data and existing literature further suggest that such improvements are largely driven by adaptations in non-paretic leg movements, notably at the hip. By providing real-time information on walking movements not affordable in other ways, avatar-based feedback shows great potential to improve gait symmetry and interlimb coordination post-stroke.

Characteristics of submental muscles function and hyoid bone movement in patients with dysphagia after stroke
Submental muscles electromyographic signal changes in patients may be the result of uncoordinated muscle contractions and decreased muscle strength. Furthermore, the reduced hyoid movement distance may be due to impaired function of the submental muscles. In addition, the submental muscles and hyoid movement or other swallowing structures functions were impaired to varying degrees, resulting in the disappearance of the correlation between the maximum movement distance of the hyoid and the peak amplitude.

Ankle stiffness modulation during different gait speeds in individuals post-stroke
Individuals post-stroke did not modulate their ankle quasi-stiffness with increased speed, but across individuals there was a positive relationship between ankle quasi-stiffness and both speed and peak propulsion. Walking speed and propulsion are limited in individuals post-stroke, therefore, improving either could lead to a higher functional status. Understanding post-stroke ankle stiffness may be important in the design of therapeutic interventions and exoskeletons, where these devices augment the biological ankle quasi-stiffness to improve walking performance.

Contribution of stroke-related changes in neuromuscular factors to gear ratio during isometric contraction of medial gastrocnemius muscle: A simulation study
Our findings provide insight that the pennation angle may play an important role for efficient muscular contraction, implying that maintaining muscle architecture and/or improving fiber/fascicle rotation could a key goal in rehabilitation interventions. Our findings will help us to better interpret altered gearing behavior in aging and pathological muscles.

Structural and passive mechanical properties of the medial gastrocnemius muscle in ambulatory individuals with chronic stroke
Although muscle mechanical properties increased exponentially over the slack ankle, measures between paretic and non-paretic sides were similar in ambulating participants with chronic stroke. Side-to-side differences in structural and morphological measures suggest the impact of stroke was relatively more pronounced for these muscle parameters than for passive mechanical properties.

Differences in paretic lower limb loading and fluidity in sit-to-walk according to selection of the leading limb in individuals with stroke
Sit-to-walk with the paretic leading limb seems to be an adaptive movement because many participants preferred leading with the paretic limb. However, selection of the leading limb in sit-to-walk involves a biomechanical tradeoff between paretic limb loading at seat-off and movement fluidity in individuals with stroke. Use of the paretic leading limb requires loading capacity of this limb, and the non-paretic leading limb must have high balance ability to merge sit-to-stand and gait initiation.

The effect of three dimensional printing hinged ankle foot orthosis for equinovarus control in stroke patients
Dynamic plantar pressure measurement is useful for evaluation of equinovarus deformity in hemiplegic stroke patients. Wearing 3D printed ankle foot orthosis increase plantar pressure in medial midfoot area. And medial midfoot contact area is also more symmetry.
