O 049 —Post-stroke balance responses after lateral perturbations to pelvis during treadmill walking
Ability to maintain balance during walking is often reduced in stroke survivors, where the activity of non-paretic leg after external gait perturbations usually compensates for the reduced activity of the paretic leg [1].

O 081 - Diagnostic value of the Duncan Ely test for assessing abnormal activity of the Rectus femoris during gait in stroke patients
Stiff knee gait is characterized by a diminished knee flexion during swing [1] and is commonly observed in children with cerebral palsy and stroke patients and can result in problems with footclearance leading to tripping and an increased risk of falling. Abnormal activity of the rectus femoris is often cited as one of the main causes of stiff knee gait [2]. The gold standard for measuring abnormal activity of the rectus femoris is electromyography. A clinical tool to assess abnormal activity of the m.

O 079 - Walking across the street: Gait adaptations in stroke patients when approaching an elevated surface
In stroke survivors that regain walking, outdoor walking is an important aim [1]. To achieve that, the management of tasks such as adapting to different levels (e.g. managing curbs) is essential. This needs locomotor pointing [2] and precise step regulation, including appropriate adaptation of joint kinematics to clear an obstacle and ensure correct positioning of the feet in relation to targets. This has to be achieved despite physical constraints, impaired balance and motor regulation (Fig. 1).

P 159 - Gait in stroke patients is influenced by upper limb functioning: a quantitative analysis correlating QuickDASH with Instrumented TUG and 10MWT
Loss of mobility after stroke is one of the main target of intervention in PRM and physiotherapy as motor impairment affects gait efficacy and upper limb function [1,2]: it is possible to observe a consensual improvement of these latter aspect throughout rehabilitation. Neural connections between upper and lower limb in gait are known [3,4] as well as the fact that modifications of upper limb movement during gait can affect gait parameters [5]. A recent review supports the inclusion of arm activity in addition to leg activity as a component of gait retraining after neurotrauma [6].

The effects of an articulated ankle-foot orthosis with resistance-adjustable joints on lower limb joint kinematics and kinetics during gait in individuals post-stroke
This study demonstrated that the adjustments of resistance in the ankle-foot orthosis with the Triple Action joints influenced ankle and knee kinematics in individuals post-stroke. Further work is necessary to investigate the long-term effects of the articulated ankle-foot orthoses on their gait.

Impact of gait analysis (GA) on treatment appropriateness in stroke patients with stiff knee gait
Introduction: Stiff Knee Gait (SKG) is the second most frequent lower limb deformity in stroke survivors. It is typically treated by means of inhibition of quadriceps femoris (QF) muscles by botulinum toxin, because of the presence of QF spasticity at the clinical evaluation [1]. Gait analysis (GA)-based studies showed that the inadequate ankle push-off (APO) can result in SKG, too [2]. We recently presented an algorithm, based on GA data, that differentiates the individual's main cause of SKG between SKG consequent to QF spasticity (SKGQF) and SKG consequent to the lack of APO (SKGAPO) [3].

Dynamic Balance during level walking in patients affected by Multiple Sclerosis, Stroke and Parkinson's disease
Introduction: Balance disorders are a common feature in patients affected by Multiple Sclerosis (MS), Stroke (ST) and Parkinson's disease (PD) generally conditioning their walking ability. These persons adopt a gait strategy that help them preventing falls. Maintaining of this stable gait require balance control, where sensory feedback is integrated to sense the position and the velocity of Center of Mass (CoM) [1]. On the basis of this information a dynamic balance is reached and maintained with appropriated foot placement to stabilize and redirect the CoM.

Transitions sit to stand and stand to sit in persons post-stroke: Path of centre of mass, pelvic and limb loading – A pilot study
In contrast to assumptions often made with respect to limb loading, we found large variability in movement patterns utilized by person's with a hemiparetic presentation during sit to stand and stand to sit. The findings suggest that movement problems encountered by persons post-stroke are complex and identifies limitations with respect to current measurement techniques.

Shear wave elastography potential to characterize spastic muscles in stroke survivors: Literature review
Shear wave ultrasound elastography can provide useful quantitative information on the mechanical properties of the spastic muscles in post-stroke patients. Nevertheless, new studies using common terminology and parameters are needed to develop reliable methods that could help in assessing treatment efficiency.
