Slacklining and stroke: A rehabilitation case study considering balance and lower limb weakness.
Authors: Gabel CP, Rando N, Melloh M Abstract To ascertain the effectiveness of slacklining as a supplementary therapy for elderly stroke patients who are functionally non-progressing. This case study involved an 18-mo prospective observation of the management of an 87-year-old female stroke-patient of the left hemisphere with reduced balance, reduced lower limb muscular activation, hypertonia, and concurrent postural deficits. This entailed the initial acute care phase through to discharge to home and 18-mo final status in her original independent living setting. The introduction of slacklining as an adjunct thera...

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).

Shoulder surgery in beach chair position causing perioperative stroke: Four cases and a review of the literature
Publication date: Available online 27 May 2019Source: Journal of OrthopaedicsAuthor(s): J.H.J. van Erp, M. Ostendorf, J.R. LansdaalAbstractPerioperative stroke is a rare, but serious complication in shoulder-arthroscopy or arthroplasty. Recent literature suggests the beach chair position, widely used during shoulder surgery, might induce severe perioperative hypotension, and with this cerebral desaturation and ultimately perioperative stroke. In this article we report four cases of perioperative stroke in shoulder surgery. In all cases, patients underwent brief periods of hypotension, which might have caused perioperative ...

Factors associated with stroke formation in blunt cerebrovascular injury: An EAST multicenter study
BACKGROUND Stroke risk factors after blunt cerebrovascular injury (BCVI) are ill-defined. We hypothesized that factors associated with stroke for BCVI would include medical therapy (i.e., Aspirin), radiographic features, and protocolization of care. METHODS An Eastern Association for the Surgery of Trauma–sponsored, 16-center, prospective, observational trial was undertaken. Stroke risk factors were analyzed individually for vertebral artery (VA) and internal carotid artery (ICA) BCVI. Blunt cerebrovascular injuries were graded on the standard 1 to 5 scale. Data were from the initial hospitalization only. R...

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...

Correlations between ankle–foot impairments and dropped foot gait deviations among stroke survivors
Abstract: Background: The purpose of this paper is to 1) evaluate the relationship between ankle kinematics during gait and standardized measures of ankle impairments among sub-acute stroke survivors, and 2) compare the degree of stroke-related ankle impairment between individuals with and without dropped foot gait deviations.Methods: Fifty-five independently ambulating stroke survivors participated in this study. Dropped foot was defined as decreased peak dorsiflexion during the swing phase and reduced ankle joint motion in stance. Standardized outcome measures included the Chedoke–McMaster Stroke Assessment (motor impa...

Minimally Invasive Soft Tissue Release of Foot and Ankle Contracture Secondary to Stroke
We present the case of a 61-year-old female with an equinovarus foot contracture deformity secondary to stroke. The patient underwent Achilles tendon lengthening, posterior tibial tendon Z lengthening, and digital flexor tenotomy of each toe with immediate weightbearing in a walking boot, followed by transition to an ankle-foot orthosis. The surgical principles and technique tips are presented to demonstrate our minimally invasive approach to release of foot and ankle contracture secondary to stroke. The main goal of this approach is to improve foot and ankle alignment for ease of bracing, which, in turn, will improve gai...

Predictors of low bone mineral density of the stroke-affected hip among ambulatory individuals with chronic stroke
Conclusion Low BMD of the stroke-affected side hip is prevalent in over a third of individuals with lower limb motor impairments. These individuals may be at particular risk of accelerated loss of BMD at the hip from asymmetrical gait pattern and poor affected-side ankle dorsiflexor strength. These impairments are intervention targets that may be addressed during rehabilitation which includes resistance training and addresses gait impairments.

Tennis Service Stroke Benefits Humerus Bone: Is Torsion the Cause?
Abstract Regular tennis play is associated with impressive asymmetries in bone strength in favor of the racquet arm, particularly in the humerus. However, the relative effects of service and ground strokes are not known. Serendipitously, we encountered a 46-year-old regular tennis player who has played service and ground strokes with different arms for over 30 years, and thus allowed differentiation of stroke effects. Grip strength and peripheral quantitative computed tomography scans of both arms of radius at 4 % distal–proximal ulna length, radius and ulna at 60 % distal–proximal ulna length, and at dista...

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.

Between-day reliability of triceps surae responses to standing perturbations in people post-stroke and healthy controls: a high-density surface EMG investigation
Deficits in muscle activation are an important contributor to disability in mobility function in people after stroke [1]. For this reason, surface electromyography (EMG) is used by researchers to investigate changes in neuromuscular recruitment strategies associated with stroke in longitudinal studies [2–4]. Recent evidence suggests that surface electromyography could be useful in clinical settings to give an indication of motor recovery after stroke [5,6], as well as for biofeedback [7] as an intervention for lower limb [8] and upper limb [9] impairments post-stroke.

Efficacy of a newly designed trunk orthosis with joints providing resistive force in adults with post-stroke hemiparesis
Conclusion: The newly designed trunk orthosis effectively modified trunk alignment, but larger improvements in kinetic and kinematic parameters were observed in the bilateral limbs after newly designed trunk orthosis removal than with the newly designed trunk orthosis. Clinical relevance Stroke patients improved only trunk malalignment while wearing the newly designed trunk orthosis. Gait after newly designed trunk orthosis removal was better than with the newly designed trunk orthosis. Positive changes after removal were mostly observed in pre-swing of the hemiparetic limb. The newly designed trunk orthosis might be effe...
