The stroke-related effects of hip flexion fatigue on over ground walking
Highlights: Abstract: Individuals post stroke often rely more on hip flexors for limb advancement during walking due to distal weakness but the effects of muscle fatigue in this group is not known. The purpose of this study was to quantify how stroke affects the influence of hip flexor fatigue on over ground walking kinematics and performance and muscle activation. Ten individuals with chronic stroke and 10 without stroke (controls) participated in the study. Maximal walking speed, walking distance, muscle electromyograms (EMG), and lower extremity joint kinematics were compared before and after dynamic, submaximal fatigui...

The effect of stroke on foot kinematics and the functional consequences
Conclusions: This study provides evidence of structural and movement deficiencies in the intrinsic foot segments affected by stroke. These would not have been detectable using a single segment foot model. Data do not support common clinical practices that focus on correction of sagittal ankle deformity and assumed excessive foot supination. Some of these abnormalities were associated with limitation in functional ability. Biomechanical abnormalities of foot and ankle are modifiable and there is potential for clinical studies and future developments of interventions to help prevent or treat these abnormalities which may imp...

Sequence of onset latency of body segments when turning on-the-spot in people with stroke
Conclusion Similarities between the groups may be because the time since the stroke was long and therefore some recovery of function may have occurred. Slowness of movement in people with stroke may predispose them to falls.

Mediolateral foot placement ability during ambulation in individuals with chronic post-stroke hemiplegia
Highlights: Abstract: Mediolateral (ML) foot placement is an effective way to redirect the lateral trajectory of the body center of mass (BCoM) during ambulation, but has only been partly characterized in the chronic post-stroke population despite their increased risk for falling . During able-bodied gait, the locomotor system coordinates lower limb swing phase kinematics such that an appropriate ML foot placement occurs upon foot contact. Muscle weakness and abnormal motor patterns may impair foot placement ability post-stroke. The purpose of this study was to characterize ML foot placement ability during post-stroke ambu...

Determinants and consequences for standing balance of spontaneous weight-bearing on the paretic side among individuals with chronic stroke
This study explores the prevalence and clinical determinants of stance asymmetry, and the relationship between stance asymmetry and postural control among chronic stroke patients. Subjects (n=147;>6 months post-stroke) stood on two force plates in eyes-open and eyes-closed conditions; 59 were symmetric, 18 had paretic asymmetry (PA), and 70 had non-paretic asymmetry (NPA). Root mean square (RMS) of antero-posterior and medio-lateral centre-of-pressure under each limb and both limbs combined were compared. RMS of total medio-lateral centre-of-pressure was greater for both asymmetric groups compared with the symmetric group....

Relationships between frontal-plane angular momentum and clinical balance measures during post-stroke hemiparetic walking
This study tests whether frontal-plane H is significantly correlated to clinical balance tests that could be used to provide a detailed assessment of medial–lateral balance impairments in hemiparetic gait. H was measured in post-stroke (n=48) and control (n=20) subjects. Post-stroke there were significant negative relationships between the change in frontal-plane H during paretic single-leg stance and two clinical tests: the Dynamic Gait Index (DGI) (r=−0.57, p

Obstacle crossing following stroke improves over one month when the unaffected limb leads, but not when the affected limb leads
Highlights: Abstract: While it is well established that obstacle crossing is impaired following stroke, it is not known whether obstacle crossing improves as gait improves following stroke. The purpose of this study was to determine whether obstacle crossing changed over a one month time period in people with a recent stroke. Twenty participants receiving rehabilitation following a recent stroke were tested on two occasions one month apart. Participants received usual care rehabilitation, including physiotherapy, between the tests. The main outcome measure was obstacle crossing speed as participants stepped over a 4-cm hig...

Haptic-based perception-empathy biofeedback system for balance rehabilitation in patients with chronic stroke: Concepts and initial feasibility study
Stroke is the leading cause of long-term disability, annually experienced by approximately 250,000 individuals in Japan and remains a major healthcare and economic issue [1]. In stroke patients, a complex interplay of sensory, motor, and cognitive impairments causes balance issues [2]. Therefore, most stroke patients show increased postural sway during quiet standing and asymmetric weight distribution [2 –4]. Regarding post-stroke balance disability, impaired balance reportedly predicts falls in elderly patients post stroke [5].

Long-lasting actigraphic monitoring of the upper and lower limbs movements in acute stroke patients: A COMMAS spin-off study
Introduction: In acute stroke patients detecting modifications of motor deficits could be crucial both for a prompt medical assistance and for a better definition of patient's prognosis. The stroke unit represents the gold standard in the management of the acute stroke with a multiparametric monitoring of vital functions, while no instruments are actually implemented in stroke unit for a continuous monitoring of patients motor performance. In a pilot study [1] we found that a 24hours actigraphic recording is informative of the overall neurological clinical picture as measured by NIH Stroke Scale (NIHSS).

Relationship between asymmetry of quiet standing balance control and walking post-stroke
This study involved review of data from 94 individuals with stroke referred to a gait and balance clinic. Participants completed three tests: (1) walking at their usual pace; (2) quiet standing; and (3) standing with maximal loading of the paretic side. A pressure sensitive mat recorded placement and timing of each footfall during walking. Standing tests were completed on two force plates to evaluate symmetry of weight bearing and contribution of each limb to balance control. Multiple regression was conducted to determine the relationships between symmetry during standing and swing time, stance time, and step length symmet...

Evaluation of a robotic knee brace during the performance of functional tasks in stroke survivors
Introduction: Nearly 800,000 people suffer a stroke each year in the US alone [1]. Approximately 85% of these individuals survive. Fifty-five percent of stroke survivors experience significant residual motor impairments and are admitted to an inpatient rehabilitation facility or a skilled nursing facility [1]. The restoration of gait function is a major goal of stroke rehabilitation. Different gait training techniques are used in stroke rehabilitation, including the use of robotic systems designed to facilitate gait [2].

Relationships between fear of falling, balance confidence, and control of balance, gait, and reactive stepping in individuals with sub-acute stroke
Fall risk for individuals with stroke is over twice that of healthy older adults [1]. Falling is a common medical complication post-stroke [2,3], with an especially high risk of occurrence during hospital stay [4] and after discharge home from in-patient rehabilitation [5]. Falls often contribute to fear of falling (FOF), or FOF can develop in absence of a fall [6]. FOF is prevalent post-stroke, with up to 88% of individuals with stroke who experience a fall developing FOF [7]. Resulting activity avoidance may lead to restricted mobility and deconditioning, contributing to reduced functional capabilities, loss of functiona...

A novel and simple test of gait adaptability predicts gold standard measures of functional mobility in stroke survivors
The ability to adjust the on-going walking pattern in response to environmental and task goals is key to regaining independent mobility in the community following stroke. However, reports indicate few stroke survivors can independently climb stairs and inclines, and walk the speeds and distances required for mobility in the community [1,2]. Further reports indicate that after a stroke most falls are caused by trips, slips, or misplaced steps while walking [3,4]. This suggests that an inability to adapt the walking pattern in response to the environment may be a key factor limiting recovery of independent mobility in stroke survivors.
