RESUMO

Background/Study Context: Older adults show a greater response to feedback whilst learning than younger adults. To date this has only been shown for receiving veridical feedback, but there is evidence that suggests that receiving false positive feedback may further enhance learning. We tested the hypothesis that receiving false positive feedback, being told you are preforming better than expected, would be more advantageous for older than younger adults when learning an inhibitory-action task. Methods: 42 younger and 34 older adults trained to improve their inhibition and response times on the Simon task. They completed 18 training blocks and a retention test two weeks after training. Participants received either false positive feedback or veridical feedback on their performance at the end of each training session and the start of the next session. Those in the false positive feedback group were told they were performing faster than expected. Results: Both older and younger adults improved their inhibition and response times but receiving false positive feedback did not significantly change their rate of learning on these outcomes. However, false positive feedback did impact on accuracy levels with those receiving this type of feedback making fewer errors. Older adults were slower but more accurate than younger adults, but contrary to our hypothesis they did not benefit more from false positive feedback than younger adults. Conclusion: This first direct comparison of the effects of false positive feedback on older and younger adults showed that the positive impact of false positive feedback does not decline with age. We also demonstrated that feedback given about one aspect of a skill (in this case speed) may in fact influence another aspect of the skill (in this case accuracy). This suggests that false positive feedback could be used as a motivational tool to enhance cognitive-motor learning in older adults, but care needs to be taken when using this, as the feedback may not affect the element of the skill at which it is targeted.

RESUMO

BACKGROUND: Rehabilitation improves poststroke recovery with greater effect for many when applied intensively within enriched environments. The failure of health care providers to achieve minimum recommendations for rehabilitation motivated the development of a technology-enriched rehabilitation gym (TERG) that enables individuals under supervision to perform high-intensity self-managed exercises safely in an enriched environment. OBJECTIVE: This study aimed to assess the feasibility of the TERG approach and gather preliminary evidence of its effect for future research. METHODS: This feasibility study recruited people well enough to exercise but living with motor impairment following a stroke at least 12 months previously. Following assessment, an 8-week exercise program using a TERG (eg, virtual reality treadmills, power-assisted equipment, balance trainers, and upper limb training systems) was structured in partnership with participants. The feasibility was assessed through recruitment, retention, and adherence rates along with participant interviews. Effect sizes were calculated from the mean change in standard outcome measures. RESULTS: In total, 70 individuals registered interest, the first 50 were invited for assessment, 39 attended, and 31 were eligible and consented. Following a pilot study (n=5), 26 individuals (mean age 60.4, SD 13.3 years; mean 39.0, SD 29.2 months post stroke; n=17 males; n=10 with aphasia) were recruited to a feasibility study, which 25 individuals completed. Participants attended an average of 18.7 (SD 6.2) sessions with an 82% attendance rate. Reasons for nonattendance related to personal life, illness, weather, care, and transport. In total, 19 adverse events were reported: muscle or joint pain, fatigue, dizziness, and viral illness, all resolved within a week. Participants found the TERG program to be a positive experience with the equipment highly usable albeit with some need for individual tailoring to accommodate body shape and impairment. The inclusion of performance feedback and gamification was well received. Mean improvements in outcome measures were recorded across all domains with low to medium effect sizes. CONCLUSIONS: This study assessed the feasibility of a holistic technology-based solution to the gap between stroke rehabilitation recommendations and provision. The results clearly demonstrate a rehabilitation program delivered through a TERG is feasible in terms of recruitment, retention, adherence, and user acceptability and may lead to considerable improvement in function, even in a chronic stroke population.

RESUMO

Movement sonification is emerging as a useful tool for rehabilitation, with increasing evidence in support of its use. To create such a system requires component considerations outside of typical sonification design choices, such as the dimension of movement to sonify, section of anatomy to track, and methodology of motion capture. This review takes this emerging and highly diverse area of literature and keyword-code existing real-time movement sonification systems, to analyze and highlight current trends in these design choices, as such providing an overview of existing systems. A combination of snowballing through relevant existing reviews and a systematic search of multiple databases were utilized to obtain a list of projects for data extraction. The review categorizes systems into three sections: identifying the link between physical dimension to auditory dimension used in sonification, identifying the target anatomy tracked, identifying the movement tracking system used to monitor the target anatomy. The review proceeds to analyze the systematic mapping of the literature and provide results of the data analysis highlighting common and innovative design choices used, irrespective of application, before discussing the findings in the context of movement rehabilitation. A database containing the mapped keywords assigned to each project are submitted with this review.

RESUMO

Major depressive disorder (MDD) is associated with biased perception of human movement. Gesture is important for communication and in this study we investigated neural correlates of gesture perception in MDD. We hypothesised different neural activity between individuals with MDD and typical individuals when viewing instrumental and expressive gestures that were negatively or positively valenced. Differences were expected in brain areas associated with gesture perception, including superior temporal, frontal, and emotion processing regions. We recruited 12 individuals with MDD and 12 typical controls matched on age, gender, and handedness. They viewed gestures displayed by stick figures while functional magnetic resonance imaging (fMRI) was performed. Results of a random effects three-way mixed ANOVA indicated that individuals with MDD had greater activity in the right claustrum compared to controls, regardless of gesture type or valence. Additionally, we observed main effects of gesture type and valence, regardless of group. Perceiving instrumental compared to expressive gestures was associated with greater activity in the left cuneus and left superior temporal gyrus, while perceiving negative compared to positive gestures was associated with greater activity in the right precuneus and right lingual gyrus. We also observed a two-way interaction between gesture type and valence in various brain regions.

RESUMO

BACKGROUND: Following stroke, rates of mood disorder are and remain high at five years (anxiety 34.4%; depression 23%). Structured mindfulness-based stress reduction (MBSR) courses are effective in a range of health conditions, but stroke survivors find adherence challenging. We aimed to adapt a standard MBSR course specifically for people affected by stroke. METHODS: We recruited stroke survivors and family members with symptoms of anxiety and/or depression to take part in a co-development study comprising two rounds of MBSR 'taster' sessions, followed by focus groups in which views were sought on the practices sampled. Data were collected in October 2017 and May 2018 and were analysed using framework analysis, informed adaptations to mindfulness materials and delivery. RESULTS: Twenty-eight stroke survivors and seven family members participated. Nineteen (76%) stroke survivors had anxiety; 15 (60%) had depression. Five (71.4%) family members reported anxiety; n = 4 (57.1%) depression. Thirty participants attended the first round of taster sessions and focus groups; twenty (66%) the second and three (10%) were unable to attend either round. Framework analysis informed adaptations to course delivery, practices, and materials, ultimately resulting in a stroke-specific MBSR course, HEADS: UP (Helping Ease Anxiety and Depression after Stroke). CONCLUSIONS: HEADS: UP may provide a feasible, appropriate, and meaningful self-management intervention to help alleviate symptoms of mood disorder.

RESUMO

BACKGROUND: Physical activity can positively influence health for older adults. Primary care is a good setting for physical activity promotion. OBJECTIVE: To assess the feasibility of a pedometer-based walking programme in combination with physical activity consultations. DESIGN: Two-arm (intervention/control) 12-week randomized controlled trial with a 12-week follow-up for the intervention group. SETTING: One general practice in Glasgow, UK. PARTICIPANTS: PARTICIPANTS were aged ≥65 years. The intervention group received two 30-minute physical activity consultations from a trained practice nurse, a pedometer and a walking programme. The control group continued as normal for 12 weeks and then received the intervention. Both groups were followed up at 12 and 24 weeks. OUTCOME MEASURES: Step counts were measured by sealed pedometers and an activPALTM monitor. Psychosocial variables were assessed and focus groups conducted. RESULTS: The response rate was 66% (187/284), and 90% of those randomized (37/41) completed the study. Qualitative data suggested that the pedometer and nurse were helpful to the intervention. Step counts (activPAL) showed a significant increase from baseline to week 12 for the intervention group, while the control group showed no change. Between weeks 12 and 24, step counts were maintained in the intervention group, and increased for the control group after receiving the intervention. The intervention was associated with improved quality of life and reduced sedentary time. CONCLUSIONS: It is feasible to recruit and retain older adults from primary care and help them increase walking. A larger trial is necessary to confirm findings and consider cost-effectiveness.

RESUMO

BACKGROUND: In Scotland, older adults are a key target group for physical activity intervention due to the large proportion who are inactive. The health benefits of an active lifestyle are well established but more research is required on the most effective interventions to increase activity in older adults. The 'West End Walkers 65+' randomised controlled trial aims to examine the feasibility of delivering a pedometer-based walking intervention to adults aged 65 years through a primary care setting and to determine the efficacy of this pilot. The study rationale, protocol and recruitment process are discussed in this paper. METHODS/DESIGN: The intervention consisted of a 12-week pedometer-based graduated walking programme and physical activity consultations. Participants were randomised into an immediate intervention group (immediate group) or a 12-week waiting list control group (delayed group) who then received the intervention. For the pilot element of this study, the primary outcome measure was pedometer step counts. Secondary outcome measures of sedentary time and physical activity (time spent lying/sitting, standing or walking; activPAL™ monitor), mood (Positive and Negative Affect Schedule), functional ability (Perceived Motor-Efficacy Scale for Older Adults), quality of life (Short-Form (36) Health Survey version 2) and loneliness (UCLA Loneliness Scale) were assessed. Focus groups with participants and semi-structured interviews with the research team captured their experiences of the intervention. The feasibility component of this trial examined recruitment via primary care and retention of participants, appropriateness of the intervention for older adults and the delivery of the intervention by a practice nurse. DISCUSSION: West End Walkers 65+ will determine the feasibility and pilot the efficacy of delivering a pedometer-based walking intervention through primary care to Scottish adults aged 65 years. The study will also examine the effect of the intervention on the well-being of participants and gain an insight into both participant and research team member experiences of the intervention.

RESUMO

Poor social functioning is a prevalent complaint of unipolar depression, but subjective experiences of social interactions have not been systematically studied. A limited number of qualitative researchers have specifically addressed the social difficulties in depression. We conducted in-depth semistructured interviews with 11 depressed women. Thematic analysis was used to analyze the transcripts. Five themes emerged. The first two, diminished desire to socially interact and fear of social interactions, encompass perceptions that have not been previously reported. The third theme, the pressure to adhere to social norms, provided support for previous findings. The final two themes, the perceptions of others and isolation, elaborated on existing knowledge. We found that difficulties with social engagements are much broader than previously reported, with a lack of interest in others, being too emotionally overloaded to interact, perceptions that other people will not understand how women with depression are feeling, and fears of being a burden all contributing to the difficulties experienced in depression.

RESUMO

Background: The prevalence of disabling conditions is increasing globally. Rehabilitation improves function and quality of life across many conditions, particularly when applied intensively. The limited workforce, however, cannot deliver evidence-based intensive rehabilitation. By providing individuals with the tools for self- rehabilitation, technology helps bridge the gap between evidence and practise. Few people, however, can access rehabilitation technology. Barriers such as cost, training, education, portability and poor design stand in the way of equitable access. Our group of engineers and researchers have established a centre dedicated to developing accessible technology through close, frequent engagement with users and industry. Methods: The centre employs a co-creation model, coupling engineering and science with user experience and industrial partnerships to develop accessible technology and associated processes. Due to the complexity and size of the challenge the initial focus is stroke. Recruited through a medical charity, participants, with a wide range of disabilities, use prototype and commercial technology during an 8-week rehabilitation programme with supervision from health professionals. The centre includes de-weighting systems, neurostimulation, virtual reality, treadmills, bespoke rehab games, communication apps, powered exercise equipment and gamified resistance equipment. Standard outcome measures (International Classification of Functioning, Disability and Health) are recorded before, during, immediately after, and 3 months after the intervention and used in combination with an interview to design the initial rehabilitation programme, which is reviewed fortnightly. Qualitative methods (surveys and interviews) are used to capture personal experiences of the programme and individual technology and an advisory group of stroke survivors help interpret outcomes to feed into the technology design process. Ethical approval has been granted for a pilot cohort study with stroke survivors, which is currently underway (01/09/2021-31/12/2021) investigating acceptability and feasibility, due to report findings in 2022. Discussion: Through partnerships, research collaborations and a co-creation model a new centre dedicated to the development of accessible rehabilitation technology has been launched and currently undergoing acceptability and feasibility testing with stroke survivors. The centre, through its close engagement with users and industry, has the potential to transform the way rehabilitation technology is developed and help revolutionise the way rehabilitation is delivered.

RESUMO

BACKGROUND: Multiple studies have highlighted the negative impact of COVID-19 and its particular effects on vulnerable sub-populations. Complementing this work, here, we report on the social patterning of self-reported positive changes experienced during COVID-19 national lockdown in Scotland. METHODS: The CATALYST study collected data from 3342 adults in Scotland during weeks 9-12 of a national lockdown. Using a cross-sectional design, participants completed an online questionnaire providing data on key sociodemographic and health variables, and completed a measure of positive change. The positive change measure spanned diverse domains (e.g., more quality time with family, developing new hobbies, more physical activity, and better quality of sleep). We used univariate analysis and stepwise regression to examine the contribution of a range of sociodemographic factors (e.g., age, gender, ethnicity, educational attainment, and employment status) in explaining positive change. RESULTS: There were clear sociodemographic differences across positive change scores. Those reporting higher levels of positive change were female, from younger age groups, married or living with their partner, employed, and in better health. CONCLUSION: Overall our results highlight the social patterning of positive changes during lockdown in Scotland. These findings begin to illuminate the complexity of the unanticipated effects of national lockdown and will be used to support future intervention development work sharing lessons learned from lockdown to increase positive health change amongst those who may benefit.

RESUMO

OBJECTIVE: The negative consequences of coronavirus disease 2019 (COVID-19) national lockdowns have been well documented, including the worsening of mental health for many and the amplification of preexisting inequalities. As a counterpoint, the current study uses a mixed-methods coproduction approach to share psychosocial insights into the adoption of positive changes made during national lockdown in Scotland. This study examines the psychosocial patterning of positive behavior changes and the psychosocial processes by which positive change was realized and shared these insights with partner organizations. METHOD: A sequential mixed-methods design included an online survey (N = 2,445) assessing positive changes in sleep and physical activity patterns and the role of sociodemographics, mood, social support, coping, and resilience using multivariate logistic regression analysis. Interviews were performed with a purposive diverse subsample of people self-reporting high levels of positive change (n = 48) and used thematic analysis. RESULTS: The survey identified that positive behavior change was significantly patterned by age, gender, and vulnerability to COVID-19. Higher levels of positive reframing and active coping in relation to stress were associated with higher levels of positive behavior change. Higher symptoms of depression, planning, and self-distraction were associated with less positive behavior change. Thematic analysis showed the centrality of perceptions of time, opportunities to self-reflect and engage with the natural world, access support in diverse ways, actively build routine, and purposefully build self-efficacy and a sense of control were key to initiating positive change. CONCLUSIONS: The current study yields insights into achieving positive behavior change at a time of international crisis. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

RESUMO

We examine the impact of the COVID-19 outbreak and concomitant restrictions (i.e., lockdown) on 24-hour movement behaviors (i.e., physical activity, sitting, sleep) in a purposive sample of people (n = 3230) reporting change recruited online. Participants' self-reported time spent in moderate-to-vigorous physical activity (MVPA), walking, sitting and sleep prior to lockdown (T1), during the first national lockdown (T2) and as restrictions initially started to ease (T3). For each 24-hour movement behavior, category-shifts are reported (positive, negative or did not change), as well as the percentage of participants recording positive/negative changes across clusters of behaviors and the percentage of participants recording improvement or maintenance of change across time. From T1 to T2 walking decreased, whereas MVPA, sitting and sleep increased, from T2 to T3 levels returned to pre-lockdown for all but MVPA. Participants who changed one behavior positively were more likely to report a positive change in another and 50% of those who reported positive changes from T1 to T2 maintained or improved further when restrictions started to ease. The current study showed that a large proportion of the sample reported positive changes, most notably those displaying initially poor levels of each behavior. These findings will inform salutogenic intervention development.

RESUMO

OBJECTIVE: To test the dimensionality of Type-D personality, using taxometric procedures, to assess if Type-D personality is taxonic or dimensional. Type-D personality is treated as a categorical variable and caseness has been shown to be a risk factor for poor prognosis in coronary heart disease. However, at present, there is no direct evidence to support the assumption that Type D is categorical and able to differentiate true cases from noncases. METHODS: In total, 1012 healthy young adults from across the United Kingdom and Ireland completed the DS14, the standard index of Type D, and scores were submitted to two taxometric procedures MAMBAC and MAXCOV. RESULTS: Graphical representations (comparing actual with simulated data) and fit indices indicated that Type D is more accurately represented as a dimensional rather than categorical construct. CONCLUSION: Type D is better represented as a dimensional construct. Implications for theory development and clinical practice with respect to Type D are examined as well as the wider use of taxometrics within psychosomatic medicine (e.g., to investigate if there are medically unexplained syndrome taxons, such as a Gulf War Syndrome taxon).

RESUMO

Post-traumatic growth (PTG) is the phenomenon of positive change through the experience of trauma and adversity (O'Leary & Ickovics, 1995). Research suggests that the type of trauma sustained could have differing processes and outcomes from each other (Demark-wahnefried et al., 2000; Sabiston, McDonough, and Crocker, 2007). The aim of this study was to synthesize qualitative data on PTG and illness related trauma. Fifty-seven published journal articles dating from before November 1st, 2007 in PsychINFO, MEDLINE, EMBASE, Web of Knowledge and from the authors own knowledge of the area were reviewed. Key words included PTG; benefit finding; thriving and positive changes. Key themes included: 'reappraisal of life and priorities'; 'trauma equals development of self'; 'existential re-evaluation'; and 'a new awareness of the body'. Findings suggest that there are unique elements to illness related PTG and a need for additional research into the processes and outcomes of physical illness related trauma.

RESUMO

Current measures assessing older adults' functional ability detect existing limitations on essential tasks rather than changes in other aspects of functioning that could indicate future limitations. The perceived motor-efficacy scale was developed to measure capability beliefs of healthy older adults across a range of daily action tasks. Subscales were developed through interviews with older volunteers and academics, then administered to participants aged 60-96 (N=300). Factor analysis of subscale scores produced 10 subscales. These demonstrated strong internal reliability, which was replicated with a second sample aged 60-92 (N=167). The influence of perceived motor-efficacy on performance of cognitively demanding action tasks was investigated with a third sample aged 60-88 (N=134). On a task assessing the inhibition of an inappropriate action, older adults in their 80s with high confidence produced minor errors, whereas those with lower confidence produced extreme errors. On another task assessing the ability to inhibit a previously learnt action, those with high levels of perceived motor-efficacy performed better amongst those least able to inhibit, but more poorly among those most able. Perceived motor-efficacy may therefore be useful in identifying older adults at risk of functional limitations and enabling interventions before the onset of illness.

RESUMO

Action errors can put older adults at risk of injury. Our study is the first to investigate whether older adults are more prone than younger adults to making 'ironic' motor errors (i.e., actions they have been instructed not to perform), or over-compensatory motor errors (e.g., moving more to the right when instructed not to move to the left). We also investigated whether error patterns change under cognitive load, and assessed whether age effects in the ability to inhibit a prohibited action are comparable to the age decrements found in the ability to inhibit a natural perception-action coupling in the Simon task. Sixty-four older (Mean = 70.64 years, SD = 5.81) and 39 younger (Mean = 28.74 years, SD = 16.39) adults completed an avoidant instruction line-drawing task (with and without cognitive load), and the Simon task. Older adults showed significantly slower inhibition times than younger adults on the Simon task, as expected, and in line with previous research. Surprisingly, however, older adults outperformed younger adults on the avoidant instruction task, producing fewer ironic and over-compensatory errors, and they performed similarly to the younger adults under cognitive load. Age-related decrements on the Simon but not the avoidant instruction task suggests that the two different types of motor tasks involve different subtypes of inhibition which likely recruit independent cognitive processes and neural circuitry in older age. It is speculated that the older adults' superior ability to inhibit a prohibited action could be the result of age-related changes in distractibility.

RESUMO

Background: Physical activity is recommended after stroke but levels for stroke survivors are typically low. The use of indoor recumbent cycling, delivered through local government leisure facilities, may increase access to exercise among stroke survivors. Objective: This study aimed to evaluate the acceptability and feasibility of an indoor cycling program delivered through existing local government services. Methods: Participants were recruited through stroke liaison nurses and public advertising. After a home visit to assess eligibility and conduct psychological and general health assessments, participants attended their local leisure center for an initial fitness test and short battery of physical tests. Then, an 8 week training program was designed with weekly goals. Following the program the assessments were retaken along with an evaluation questionnaire. In-depth, semi-structured, interviews were conducted with 15 participants and five fitness coaches. Results: One hundred fifteen individuals volunteered to participate during a 10-month recruitment period, 77 met the inclusion criteria and consented, 66/77 (86%) completed the program including all nine non-ambulatory participants. The program and procedures (recruitment and outcome measures) were feasible and acceptable to participants (81% reported following the program). Participants were generally very positive about the experience. Significant improvements in sit-to-stand capacity (Mpre = 25.2 s, Mpost = 19.0 s, p = .002), activities of daily living (NEADL, Mpre = 12.2, Mpost = 13.2, p = .002), psychosocial functioning (SAQOL, Mpre = 3.82, Mpost = 4.15, p = .001), energy (SAQOL, Mpre = 3.75, Mpost = 4.02, p = .018) and depression (GHQ, Mpre = .97, Mpost = .55, p = .009) were observed. Conclusion: A cycling-based exercise program delivered through local leisure center staff and facilities was shown to be feasible and acceptable for people living with stroke.

RESUMO

OBJECTIVE: To (a) investigate the prevalence of type-D personality (the conjoint effects of negative affectivity and social inhibition) in a healthy British and Irish population; (b) to test the influence of type-D on health-related behavior, and (c) to determine if these relationships are explained by neuroticism. METHODS: A cross-sectional design was employed; 1012 healthy young adults (225 males, 787 females, mean age 20.5 years) from the United Kingdom and Ireland completed measures of type-D personality, health behaviors, social support, and neuroticism. RESULTS: The prevalence of type-D was found to be 38.5%, significantly higher than that reported in other European countries. In addition, type-D individuals reported performing significantly fewer health-related behaviors and lower levels of social support than non-type-D individuals. These relationships remained significant after controlling for neuroticism. CONCLUSION: These findings provide new evidence on type-D and suggest a role for health-related behavior in explaining the link between type-D and poor clinical prognosis in cardiac patients.

RESUMO

The anti-saccade task has been used to measure attentional control related to general anxiety but less so with social anxiety specifically. Previous research has not been conclusive in suggesting that social anxiety may lead to difficulties in inhibiting faces. It is possible that static face paradigms do not convey a sufficient social threat to elicit an inhibitory response in socially anxious individuals. The aim of the current study was twofold. We investigated the effect of social anxiety on performance in an anti-saccade task with neutral or emotional faces preceded either by a social stressor (Experiment 1), or valenced sentence primes designed to increase the social salience of the task (Experiment 2). Our results indicated that latencies were significantly longer for happy than angry faces. Additionally, and surprisingly, high anxious participants made more erroneous anti-saccades to neutral than angry and happy faces, whilst the low anxious groups exhibited a trend in the opposite direction. Results are consistent with a general approach-avoidance response for positive and threatening social information. However increased socio-cognitive load may alter attentional control with high anxious individuals avoiding emotional faces, but finding it more difficult to inhibit ambiguous faces. The effects of social sentence primes on attention appear to be subtle but suggest that the anti-saccade task will only elicit socially relevant responses where the paradigm is more ecologically valid.

RESUMO

This study investigated the effect of increased core temperature on the performance outcome and movement kinematics of elite golfers during a golf putting task. The study aimed to examine individual differences in the extent to which increased temperature influenced the rate of putting success, whether increased temperature speeded up the timing of the putting downswing and whether elite golfers changed their movement kinematics during times of thermal stress. Six participants performed 20 putts to each of four putt distances (1, 2, 3, and 4 m) under normal temperature conditions and when core body temperature was increased. There was no significant difference in the number of successful putts between the two temperature conditions, but there was an increase in putterhead velocity at ball impact on successful putts to distances of 1 and 4 m when temperature was elevated. This reflected an increase in swing amplitude rather than a reduction in swing duration as hypothesized. There were individual differences in the motor control response to thermal stress as three of the golfers changed the kinematic parameters used to scale their putting movements to achieve putts of different distances at elevated temperatures. Theoretical implications for these findings and the practical implications for elite golfers and future research are discussed.
