Article
BACKGROUND BDNF (brain-derived neurotrophic factor) is a biomarker of neuroplasticity linked with better functional outcomes after stroke. Early evidence suggests that increased concentrations after exercise may be possible for people with stroke, however it is unclear how exercise parameters influence BDNF concentration. METHODS This systematic r...
Article
Background Upper limb (UL) impairment in stroke survivors is both multifactorial and heterogeneous. Stratification of motor function helps identify the most sensitive and appropriate assessments, which in turn aids the design of effective and individualized rehabilitation strategies. We previously developed a stratification method combining the Gro...
Article
Full-text available
Impaired motor control post-stroke is typically measured using clinical assessments employing categorical and subjective scoring. We investigated quantitative kinematic parameters of a complex movement with therapy in chronic stroke. Tri-axial accelerometry of the more-affected arm of 24 patients was recorded during early- (day 2-3) and late- (days...
Article
Background: Education is essential to promote prevention of recurrent stroke and maximize rehabilitation; however, current techniques are limited and many patients remain dissatisfied. Virtual reality (VR) may provide an alternative way of conveying complex information through a more universal language. Aim: To develop and conduct preliminary asses...
Article
Full-text available
Importance Billing errors and healthcare fraud have been described by the WHO as ‘the last great unreduced health-care cost’. Estimates suggest that 7% of global health expenditure (US$487 billion) is wasted from this phenomenon. Irrespective of different payment models, challenges exist at the interface of medical billing and medical practice acro...
Article
Full-text available
Fine motor control is achieved through the coordinated activation of groups of muscles, or “muscle synergies.” Muscle synergies change after stroke as a consequence of the motor deficit. We investigated the pattern and longitudinal changes in upper limb muscle synergies during therapy in a largely unconstrained movement in patients with a broad spe...

Poststroke weakness on the more-affected side may arise from reduced corticospinal drive, disuse muscle atrophy, spasticity, and abnormal coordination. This study investigated changes in muscle activation patterns to understand therapy-induced improvements in motor-function in chronic stroke compared to clinical assessments and to identify the effe...
Article
Purpose: Transient ischemic attack (TIA) and mild stroke represent a large proportion of cerebrovascular events, at high risk of being followed by recurrent, serious events. The importance of early education addressing risk management, secondary prevention and lifestyle modifications is the centerpiece of further stroke prevention. However, deliver...
Article
Purpose: Post-stroke hemiparesis may manifest as asymmetric gait, poor balance, and inefficient movement patterns. We investigated improvements in lower-limb muscle activation and function during Wii-based Movement Therapy (WMT), a rehabilitation program specifically targeting upper-limb motor-function. Methods: Electromyography (EMG) was record...
Article
Full-text available
Background: Persistent motor impairment is common but highly heterogeneous poststroke. Genetic polymorphisms, including those identified on the brain-derived neurotrophic factor (BDNF) and apolipoprotein E (APOE) genes, may contribute to this variability by limiting the capacity for use-dependent neuroplasticity, and hence rehabilitation responsiv...
Article
Introduction: Post-stroke cardiovascular fitness is typically half that of healthy age-matched people. Cardiovascular deconditioning is a risk factor for recurrent stroke that may be overlooked during routine rehabilitation. This study investigated the cardiovascular responses of two upper limb rehabilitation protocols. Methods: Forty-six stroke...
Article
Full-text available
More effective and efficient rehabilitation is urgently needed to address the prevalence of unmet rehabilitation needs after stroke. This study compared the efficacy of two poststroke upper limb therapy protocols. We tested the hypothesis that Wii-based movement therapy would be as effective as modified constraint-induced movement therapy for post-...
Conference Paper
Stroke survivors directly link stroke education with their ability to access appropriate treatments and reduce their risk of future strokes. However, with such a diverse population a universal mode of delivering education must be sought. This paper places the artist at the heart of educating patients and carers about their disease by developing a t...
Article
Full-text available
Background: Functional ability is regularly monitored poststroke to assess improvement and the efficacy of clinical trials. The balance between implementation times and sensitivity has led to multidomain tools that aim to assess upper-limb function comprehensively. Objective: This study implemented 3 common multidomain tools to investigate their...
Article
Full-text available
. Neurological deficits after a stroke are commonly classified according to motor function for clinical decision making regarding discharge and rehabilitation. Participants in clinical stroke studies are also stratified by motor function to avoid a sampling bias. . This post hoc analysis examined a suite of upper limb functional assessment tools to...
Article
Full-text available
Purpose – Stroke patients with low and very low functional movement are not usually considered suitable for rehabilitation. Without therapy the more-affected side will not improve and may lose any residual function. Poor movement ability reduces independence and limits the social engagement of such patients. The purpose of this paper was to investi...
Chapter
Stroke is one of the leading causes of acquired motor disability worldwide. With no cure, the only way to recover motor function is through rehabilitation. Recent trials of Wii-based movement therapy have demonstrated improved functional ability that has transferred to greater independence in activities of daily living. This brief but intense 2-wee...
Article
Persistent motor disability limits the capacity of stroke patients to retain or regain physical fitness. Increased metabolic demands of hemiparetic gait, physical deconditioning, and secondary muscle changes including atrophy and a shift in muscle fibre phenotype, combine to reduce post-stroke aerobic capacity by ∼50%. Fitness may be overlooked in...
Conference Paper
Background Sensorimotor function is commonly impaired post-stroke. The resulting decline in hand function limits the ability of patients to live independently. Aims To investigate whether an intensive 2-week rehabilitation program of Wii-based movement therapy alters sensation, strength and dexterity of the hand and arm after stroke. Methods Tw...
