Gait stability indices and their relationship with clinical scale scores in stroke patients
Introduction: Stroke patients are at particular risk for falling [1]. Gait stability, defined as the capacity of maintaining equilibrium minimizing accelerations at upper body level [2], is considered as a major factor in fall risk assessment [3]. To quantify gait stability, clinical scales are normally used in clinics. However, they are highly operator-dependent thus lacking reliability [3]. On the other hand, objective methods exist that quantify gait stability in terms of acceleration at upper body level and its attenuation going from the lower to the upper trunk and head.

Posturography using the Wii Balance Board™. A feasibility study with healthy adults and adults post-stroke
The high incidence and prevalence of balance disorders after stroke and their implications for most daily activities make assessment and rehabilitation of balance a priority [1]. Severity of balance deficits have been traditionally assessed using clinical scales [2], which are usually easy to administer in the clinic and not time-consuming. However, balance scales and tests can be influenced by subjective bias and they provide limited sensitivity to, and information about, sensory integration [3].

Ankle muscle coactivation during gait is decreased immediately after anterior weight shift practice in adults after stroke
Gait is a fundamental component of activities of daily living, and regaining the ability to walk is a major goal of stroke rehabilitation for adults with hemiplegia [1]. Common characteristics of hemiplegic gait are decreased gait speed [2], asymmetrical gait pattern [2], and increased energetic cost [3]. These gait dysfunctions are mainly caused by impaired function of the paretic lower limb due to muscle weakness [4], sensory dysfunction [4], and disturbed control of lower limb muscle activation [5,6].

Effects of treadmill incline and speed on peroneus longus muscle activity in persons with chronic stroke and healthy subjects
Peroneus Longus (PL) muscle provides frontal plane stability during walking [1], most prominently seen in the single support phase [2]. PL with other ankle invertor and evertor muscles together maintain balance control in the frontal plane [3] and their activity significantly increases when standing on unstable surfaces [4]. Excessive activity in peroneus muscles can result in greater eversion moments and produce large medio-lateral displacements of the body [5]. Balance impairments are most commonly seen in the form of excessive medio-lateral sway in the frontal plane in persons post-stroke [6].

The instrumented Fukuda Stepping Test: Quantifying balance impairment in patients with sub-acute stroke
Introduction: Balance impairment is one of the most common consequences after a stroke event [1]. To assess the effects of this deficit, the Fukuda Stepping Test (FST), in which the subject has to step on the spot blindfolded, can be used. However, the relevant parameters traditionally considered in the clinical environment, i.e. body rotation and displacement measured from final foot position, are not fully representative of the patient's motor ability [2]. The purpose of this study is to devise an instrumented version of the FST (iFST) that embodies inertial measurement units (IMUs).

Efficacy of multilevel functional surgery in the reduction of stiff knee gait in stroke patients. A retrospective study
In this study, we assessed the efficacy of multilevel FS on SKG reduction, at one month from surgery.

Effectiveness of prowling with proprioceptive training on knee hyperextension among stroke subjects using videographic observation- a randomised controlled trial
In hemiparetic gait, an abnormal gait pattern among stroke subjects, balance impairment and increased energy consumption are commonly associated issues and if not corrected at initial stages may lead to muscle wasting and deformities [1]. Knee hyperextension a progressive, disabling, acquired deformity [2] is a frequent deviation seen among these subjects who are self-ambulant or walking with support [1,3].

Over-focused? The relation between patients ’ inclination for conscious control and single- and dual-task motor performance after stroke
A motor task like walking is often assumed to be a relatively automated task that requires minimal cognitive involvement [1,2]. However, walking may invoke enhanced degrees of conscious control in special circumstances, such as under fatigue or stress, or in special groups, such as elderly with fear of falling or rehabilitating patients.[3 –7] For example, following a stroke individuals typically become strongly inclined to consciously guide their movements, and consider this necessary for ensuring successful locomotion and preventing falls [4].

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.

P 103 – “RehaBoard” Project: Implementing an algorithm to assist the interprofessional decision-making process towards improved gait in patients after stroke
An interdisciplinary team is believed to be effective in stroke rehabilitation [1]. In the “RehaBoard” project, neurologists, orthopaedics, physiotherapists, orthotists, biomedical engineers and computer scientists collaborate to combine medical, therapeutic and technical expertise for interpreting data, to agree on interdisciplinary treatment recommendations and to develop a method t o assess gait changes after conventional interventions to tailor therapy to patient`s needs. Decision-making in interprofessional teams is complex [2], because the clinical reasoning process is unique to each profession [3].

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).
