Transcranial direct current stimulation over multiple days enhances motor performance of a grip task.
CONCLUSIONS: Anodal tDCS is effective in promoting grip motor learning in healthy individuals. Further studies are warranted to test its potential use for the rehabilitation of fine motor skills in stroke patients. PMID: 28797624 [PubMed - as supplied by publisher]

Risk factors for falls in community stroke survivors: A systematic review and meta-analysis.
CONCLUSIONS: This study confirms that balance and mobility problems, assisted self-care, taking sedative or psychotropic medications, cognitive impairment, depression, and history of falling are associated with falls in community stroke survivors. We recommend that any future research into falls prevention programs should consider addressing these modifiable risk factors. As the risk factors for falls in community stroke survivors are multifactorial, interventions should be multi-dimensional. PMID: 28797618 [PubMed - as supplied by publisher]

Image-based immersed boundary model of the aortic root.
Abstract Each year, approximately 300,000 heart valve repair or replacement procedures are performed worldwide, including approximately 70,000 aortic valve replacement surgeries in the United States alone. Computational platforms for simulating cardiovascular devices such as prosthetic heart valves promise to improve device design and assist in treatment planning, including patient-specific device selection. This paper describes progress in constructing anatomically and physiologically realistic immersed boundary (IB) models of the dynamics of the aortic root and ascending aorta. This work builds on earlier IB mod...

Pre-therapy Neural State of Bilateral Motor and Premotor Cortices Predicts Therapy Gain After Subcortical Stroke: A Pilot Study.
CONCLUSIONS: Glutamatergic state of bilateral motor and premotor cortices and neuronal state of ipsilesional premotor cortex may be important for predicting motor outcome in the context of a restorative therapy. PMID: 28737516 [PubMed - as supplied by publisher]

Feasibility and Neurobehavioral Changes of 10-Day Simulated Microgravity in Acute Ischemic Stroke Patients.
CONCLUSIONS: The 6-degree HDT revealed no adverse effects on the cardiovascular system, showing nonsignificant increment in the finger-tapping test (representative of motor speed and performance) and nonsignificant reduction in the digit backward span test (representative of spatial memory).

Physical and Occupational Therapy from the Acute to Community Setting Following Stroke: Predictors of Use, Continuity of Care, and Timeliness of Care.
CONCLUSIONS: Therapist use following stroke varies in the community and for specific sociodemographic subgroups and may be underutilized. Inpatient nurse staffing levels and primary care provider supply were the most consistent predictors of therapist use, continuity of care, and early therapist use.

The Effectiveness of Active Cycling in Subacute Stroke Rehabilitation: a Randomized Controlled Trial.
CONCLUSION: No significant differences between training groups were found over time. Although our study missed objective exercise data from the training device during follow-up, the 3-month AC program combined with education sessions seemed an applicable method in subacute stroke. New long-term AT interventions should focus on coaching approaches to facilitate training after a supervised AC program. PMID: 28284834 [PubMed - as supplied by publisher]

An articulated ankle-foot orthosis with adjustable plantarflexion resistance, dorsiflexion resistance and alignment: A pilot study on mechanical properties and effects on stroke hemiparetic gait.
Abstract Mechanical properties of an articulated ankle-foot orthosis (AFO) are closely related to gait performance in individuals post-stroke. This paper presents a pilot study on the mechanical properties of a novel articulated AFO with adjustable plantarflexion resistance, dorsiflexion resistance and alignment, and its effect on ankle and knee joint kinematics and kinetics in an individual post-stroke during gait. The mechanical properties of the AFO were quantified. Gait analysis was performed using a 3D motion capture system with a split-belt instrumented treadmill under 12 different settings of the mechanical...

Cardiovascular adjustments to heat stress during prolonged exercise.
Abstract Prolonged effort in hot environments is increasing popular in extreme sports. The number of long distance athletes taking part in races in extremely warm condition, as in deserts, is larger than in the past and also the race distances are increased thus. The demanding for the heart function are higher than those challenged in the past only by few athletes and in easier conditions. This puts news challenges on the professional involved in these activities and there is a need to better understand how the cardiocirculatory system responses in these extreme environmental conditions. This review paper is focus...

Determinants of living well with aphasia in the first year post stroke: a prospective cohort study.
CONCLUSION: Psychosocial determinants were the most significant predictors of living well with aphasia in the first 12 months post onset. Aphasia rehabilitation needs to attend more to these factors to optimise outcomes. PMID: 27457540 [PubMed - as supplied by publisher]

Effects of Respiratory Muscle Training on Respiratory Function, Respiratory Muscle Strength and Exercise Tolerance in Post-Stroke Patients: A Systematic Review with Meta-Analysis.
CONCLUSIONS: Respiratory muscle training should be considered an effective method of improving respiratory function, inspiratory muscle strength, and exercise tolerance in post-stroke patients. Further research is needed to determine optimum dosages and duration of effect. PMID: 27216224 [PubMed - as supplied by publisher]

An 8-channel RF coil array for carotid artery MR imaging in humans at 3 T.
CONCLUSIONS: Based on the analyses of phantom and in vivo imaging studies, the proposed 8-channel carotid coil array has the potential for use in clinical diagnosis, performing better in terms of SNR, imaging coverage, and penetration depth than the commercial 4-channel carotid artery coil array at 3 T. In future studies, the proposed 8-channel carotid coil array can also serve as an important part of a large-scale multichannel coil array for imaging the whole carotid artery system, including the extracranial and intracranial arteries.
