Bridging the gap between goal intentions and actions: a systematic review in patient populations

Disability and Rehabilitation (2014)

Paula Kersten Alana B. McCambridge Nicola Kayes Alice Theadom Kathryn McPherson

Purpose: To evaluate the evidence for the effectiveness of if-then implementation intentions (if-then plans) in adult patient populations.Outcomes of interest included adherence, goal pursuit and physical health outcomes.Method: Keywords were used to search electronic databases without date or language restrictions (up to 30/4/14).Studies were included if they 1) concerned a patient population;2) used if-then plans as a sole intervention or as part of treatment, therapy or rehabilitation; 3) if they were randomised controlled trials.The PEDro scale was used to evaluate study quality.Guidance as set out by the Cochrane Collaboration was used.Two reviewers independently extracted data, discrepancies were discussed and if required referred to a third reviewer.Results: 18 of 2,141 articles were identified as potentially relevant and four studies of people with epilepsy, chronic back pain, stroke and obesity met the inclusion criteria.People who form if-then plans achieved better outcomes on epilepsy and stroke medication adherence and physical capacity than controls. Conclusions:Of the four studies that used an if-then plan only one, with people with epilepsy, looked at the intervention as a stand-alone strategy.Further research needs to explore if this simple approach improves rehabilitation outcomes and is a helpful and feasible strategy for people experiencing disabilities.

Randomised controlled trial of informal team sports for cardirespiratory fitness and health benefit in Pacific Adults

Journal of Primary Health Care (2011)

Mark Biddle Grace E. Vincent Alana B. McCambridge Gabrielle B. Britton Ofa Dewes

Rates of obesity, Type 2 diabetes and cardiovascular disease are high among Pacific people in New Zealand. Physical activity is recommended in the prevention and management of these conditions. Community-based, 'small-sided game' group activities may be an effective and culturally appropriate way to promote physical activity within Pacific communities.To assess the effectiveness of small-sided games-based exercise on fitness and health parameters among Pacific adults over four weeks.Twenty untrained (13 female) Pacific adults were randomised to intervention or control. Intervention participants were offered 45 minutes of small-sided games three times per week for four weeks. Control participants were offered one-month gym membership after the trial. Primary outcomes included cardiorespiratory fitness (VO₂peak) and leg strength (maximal concentric force of quadriceps at 60°/second) measured at baseline and four weeks. Secondary outcomes included glycaemia, lipid profile, blood pressure (BP), and inflammatory markers. Multivariable regression models were used to assess differences between groups, adjusting for baseline values, age and gender.At baseline, mean age was 34.8 years (SD 12.6), BMI 36.3 (6.7), systolic BP 127.7 mmHg (12.1), HbA1c 6.1% (1.9), VO₂peak 2.5 L/min (0.6) and leg strength 170.0 N.m (57.4). Sixteen participants completed the trial. Change in outcomes were greater in intervention than control participants in absolute VO₂peak (0.9 L/min (p=0.003)), leg strength (17.8 N.m (p=0.04)) and HDL (0.12 mmol/L (p=0.02)). There were no other significant differences.Small-sided games appear to be a promising means for improving the health and cardiorespiratory fitness and reducing the risk of diabetes and cardiovascular disease in Pacific adults.

Neurorehabilitation in dystonia: a holistic perspective

Journal of Neural Transmission (2020)

Lynley V. Bradnam Rebecca M. Meiring Melani J. Boyce Alana B. McCambridge

Abstract Rehabilitation for isolated forms of dystonia, such as cervical or focal hand dystonia, is usually targeted towards the affected body part and focuses on sensorimotor control and motor retraining of affected muscles. Recent evidence, has revealed people who live with dystonia experience a range of functional and non-motor deficits that reduce engagement in daily activities and health-related quality of life, which should be addressed with therapeutic interventions. These findings support the need for a holistic approach to the rehabilitation of dystonia, where assessment and treatments involve non-motor signs and symptoms, and not just the dystonic body part. Most studies have investigated Cervical Dystonia, and in this population, it is evident there is reduced postural control and walking speed, high fear of falling and actual falls, visual compensation for the impaired neck posture, and a myriad of non-motor symptoms including pain, fatigue, sleep disorders and anxiety and depression. In other populations of dystonia, there is also emerging evidence of falls and reduced vision-related quality of life, along with the inability to participate in physical activity due to worsening of dystonic symptoms during or after exercise. A holistic approach to dystonia would support the management of a wide range of symptoms and signs, that if properly addressed could meaningfully reduce disability and improve quality of life in people living with dystonia.

Consensus Paper: Experimental Neurostimulation of the Cerebellum

The Cerebellum (2019)

Lauren N. Miterko Kenneth B. Baker Jaclyn Beckinghausen Lynley V. Bradnam Michelle Cheng

The cerebellum is best known for its role in controlling motor behaviors. However, recent work supports the view that it also influences non-motor behaviors. The contribution of the cerebellum towards different brain functions is underscored by its involvement in a diverse and increasing number of neurological and neuropsychiatric conditions including ataxia, dystonia, essential tremor, Parkinson's disease (PD), epilepsy, stroke, multiple sclerosis, autism spectrum disorders, dyslexia, attention deficit hyperactivity disorder (ADHD), and schizophrenia. Although there are no cures for these conditions, cerebellar stimulation is quickly gaining attention for symptomatic alleviation, as cerebellar circuitry has arisen as a promising target for invasive and non-invasive neuromodulation. This consensus paper brings together experts from the fields of neurophysiology, neurology, and neurosurgery to discuss recent efforts in using the cerebellum as a therapeutic intervention. We report on the most advanced techniques for manipulating cerebellar circuits in humans and animal models and define key hurdles and questions for moving forward.

Mirror Symmetric Bimanual Movement Priming Can Increase Corticomotor Excitability and Enhance Motor Learning

PLoS ONE (2012)

Winston D. Byblow Cathy M. Stinear Marie‐Claire Smith Lotte Bjerre Brian K. Flaskager

Repetitive mirror symmetric bilateral upper limb may be a suitable priming technique for upper limb rehabilitation after stroke. Here we demonstrate neurophysiological and behavioural after-effects in healthy participants after priming with 20 minutes of repetitive active-passive bimanual wrist flexion and extension in a mirror symmetric pattern with respect to the body midline (MIR) compared to an control priming condition with alternating flexion-extension (ALT). Transcranial magnetic stimulation (TMS) indicated that corticomotor excitability (CME) of the passive hemisphere remained elevated compared to baseline for at least 30 minutes after MIR but not ALT, evidenced by an increase in the size of motor evoked potentials in ECR and FCR. Short and long-latency intracortical inhibition (SICI, LICI), short afferent inhibition (SAI) and interhemispheric inhibition (IHI) were also examined using pairs of stimuli. LICI differed between patterns, with less LICI after MIR compared with ALT, and an effect of pattern on IHI, with reduced IHI in passive FCR 15 minutes after MIR compared with ALT and baseline. There was no effect of pattern on SAI or FCR H-reflex. Similarly, SICI remained unchanged after 20 minutes of MIR. We then had participants complete a timed manual dexterity motor learning task with the passive hand during, immediately after, and 24 hours after MIR or control priming. The rate of task completion was faster with MIR priming compared to control conditions. Finally, ECR and FCR MEPs were examined within a pre-movement facilitation paradigm of wrist extension before and after MIR. ECR, but not FCR, MEPs were consistently facilitated before and after MIR, demonstrating no degradation of selective muscle activation. In summary, mirror symmetric active-passive bimanual movement increases CME and can enhance motor learning without degradation of muscle selectivity. These findings rationalise the use of mirror symmetric bimanual movement as a priming modality in post-stroke upper limb rehabilitation.

Abstract spin in physiotherapy interventions using virtual reality or robotics: protocol for two Meta-research reviews

Physical Therapy Reviews (2020)

Peter W. Stubbs Poonam Mehta Lucy Bryant Rafael Zambelli Pinto Arianne P. Verhagen

Background Emerging technologies such as robotics and virtual reality (VR) are being trialled and implemented into physiotherapy practice. As emerging technologies compete for market share, trials on emerging technologies are at risk of spin. For consumers to make informed decisions about whether to use a new technology, trials should accurately portray the results. If spin is present, outcomes may not be comparable to the results reported when interventions are implemented clinically.Objectives To determine the amount and type of spin in abstracts of physiotherapy clinical trials that use robotic or VR interventions. A secondary objective is to determine the agreement between raters, both experienced and inexperienced, using an existing 7-item checklist with updated item definitions.Methods We will perform two meta-research reviews on a random set of 100 robotics (study 1) and 100 VR (study 2) trials, from any year, indexed in the PEDro database. Using the updated spin checklist, the abstract of each trial will be assessed in corroboration with full-text. The total spin score and proportion of studies with spin for each item will be reported. Agreement between experienced and inexperienced raters will be determined using kappa statistics. Rater confidence in rating each item will be collected.Discussion We will identify if spin is present in robotics and VR literature and evaluate if the spin checklist can be confidently and consistently used by raters. We hope this research will facilitate best-practice reporting of research findings so emerging technologies will be implemented with realistic expectation of clinical outcome.
