RESUMO
PURPOSE: Heart rate (HR) response is likely to vary in people with Parkinson's disease (PD), particularly for those with chronotropic incompetence (CI). This study explores the impact of CI on HR and metabolic responses during cardiopulmonary exercise test (CPET) in people with PD, and its implications for exercise intensity prescription. METHODS: Twenty-eight participants with mild PD and seventeen healthy controls underwent CPET to identify the presence or absence of CI. HR and metabolic responses were measured at submaximal (first (VT1) and second (VT2) ventilatory thresholds), and at peak exercise. Main outcome measures were HR, oxygen consumption (VO2), and changes in HR responses (HR/WR slope) to an increase in exercise demand. RESULTS: CI was present in 13 (46%) PD participants (PDCI), who during CPET, exhibited blunted HR responses compared to controls and PD non-CI beyond 60% of maximal workload (p ≤ 0.05). PDCI presented a significantly lower HR at VT2, and peak exercise compared to PD non-CI and controls (p ≤ 0.001). VO2 was significantly lower in PDCI than PD non-CI and controls at VT2 (p = 0.003 and p = 0.036, respectively) and at peak exercise (p = 0.001 and p = 0.023, respectively). CONCLUSION: Although poorly understood, the presence of CI in PD and its effect on HR and metabolic responses during incremental exercise is significant and important to consider when programming aerobic exercises.
RESUMO
BACKGROUND: Falls prevention interventions are effective for community dwelling older adults however, the same cannot be said for older adults living in long-term care (LTC). The Staying UpRight (SUp) randomized controlled trial was designed to test the effectiveness of a progressive strength and balance group exercise program delivered to LTC residents. This paper explores the factors impacting LTC providers' decisions to continue the program on completion of the funded trial period. METHODS: A qualitative study using an Interpretive Description approach. Semi-structured interviews and focus groups were conducted with 15 LTC staff involved in the randomized controlled trial. Data were analysed using conventional content analysis. RESULTS: Practice change occurred following participation in the trial with some facilities starting exercise groups, some increasing the number of exercise groups offered and physical therapists selecting elements of the program to adopt into their practice. Decisions about continuing with SUp as designed were constrained by organizational decisions regarding funding and resources. Three factors were identified which informed decision-making: business models and philosophies, requirements for evidence, and valuing physical therapy. CONCLUSIONS: Managers and facilitators adapted SUp by selecting and delivering components of the program in response to the changes they had observed in participating residents. However, our findings highlight that while SUp was valued, the tight financial environment created by the current funding model in New Zealand did not support funding physical therapist delivered falls prevention exercise programs in LTC. This study may provide policy makers with important information on changes needed to support falls prevention service delivery in LTC. TRIAL REGISTRATION: This study is a sub-study of a randomized controlled trial which was registered to the Australian New Zealand Clinical Trials Registry ACTRN12618001827224 on 09/11/2018. Universal trial number U1111-1217-7148.

INTRODUCTION: Major inequities exist in levels of health and wellbeing, availability, and access to healthcare services between seniors of Indigenous and non-Indigenous background in Ontario. First Nations elders are 45-55% more frail than the average senior in Ontario. Additionally, needed rehabilitation services are not easily accessible or available in the first language of most First Nations elders within their home communities. A literature review demonstrated community-based rehabilitation assistant models had been successfully developed and implemented in regions facing similar equity and access challenges. Building on these findings, a needs assessment was conducted to capture unique needs and requirements in Northwestern Ontario relating to rehabilitation among First Nations elders. METHODS: The needs assessment resulted in four First Nations, three Indigenous health organizations, three rehabilitation health organizations, and two academic institutions iteratively developing and evaluating curriculum for a Community Rehabilitation Worker (CRW) program in treaty territories 5, 9, and Robinson-Superior. The goal of the program is to train local CRWs, familiar with local languages and cultures, to provide rehabilitative services that support ageing in place, health, wellbeing, and quality of life for First Nations elders. The study employed a community participatory action research approach aligning with the OCAP® (Ownership, Control, Access, and Possession) framework for working with Indigenous populations. Seventeen community partners were active participants in the program development, evaluation, and adaptation of the CRW curriculum. Feedback was received through advisory committee meetings, surveys, and individual and group interviews. RESULTS: All 101 participants agreed, across all curriculum modules, that (1) the time allotment was realistic; (2) instructional materials, activities, and resources were appropriate and easy to understand; (3) evaluation activities accurately measured learning; and (4) participants identifying as Indigenous felt that Indigenous culture was adequately reflected. The qualitative findings highlighted the importance of incorporating culture, spirituality, traditions, local language use, and reintegration of First Nations elders into traditional activities and community activities for both the CRW curriculum and rehabilitation efforts. The need for locally available First Nations, elder-focused mental health support, transportation options, and gathering spaces such as those commonly seen in urban areas was also highlighted. CONCLUSION: The process of iteratively developing and evaluating a CRW program resulted in a Northwestern Ontario college welcoming the first cohort of students to the CRW program in March 2022. The program is co-facilitated with a First Nations Elder and includes components of local culture, language, and the reintegration of First Nations elders into community as part of the rehabilitation efforts. In addition, to appropriately support the quality of life, health, and wellbeing of First Nations elders, the project team called upon provincial and federal governments to work with First Nations to make available dedicated funding to address inequities in resources available to First Nations elders in Northwestern Ontario urban and First Nations remote communities. This included elder-focused transportation options, mental health services, and gathering places. The program implementation will be evaluated with the first cohort of CRWs for further adaptations considering potential scale and spread. As such, the project and findings may also represent a resource for others wishing to pursue similar development using participatory approaches in rural and remote communities both nationally and internationally.

BACKGROUND: There is increasing evidence for the potential benefits and harms of cardiovascular disease (CVD) medications in older people (>75 years) prompting updating of clinical guidelines. We explored the views of older people about CVD medication to inform guideline development. METHODS: Qualitative study using semistructured interviews and focus groups. An ethnically diverse group of community dwelling older people were purposefully recruited from northern New Zealand using flyers in primary care clinics, local libraries, social groups, and places of worship, and by word of mouth. Interviews and focus groups were digitally recorded, transcribed verbatim, and analysed using an iterative and inductive approach to thematic analysis. RESULTS: Thirty-nine participants from 4 ethnic groups were recruited (mean 74 years; range 61-91 years; Maori (7), South Asian (8), European (9), and Pasifika (15)). Most participants were taking CVD medication/s. Four main themes emerged: (i) emphasizing the benefits of CVD medication and downplaying the harms; (ii) feeling compelled to take medication; (iii) trusting "my" doctor; and (iv) expecting medication to be continued. CONCLUSION: Findings raise questions about older people's agency in decision-making regarding CVD medication. CVD risk management guidelines for older people could include strategies to support effective communication of the potential benefits and harms of CVD medication in older people, balancing life expectancy, and the expected duration of therapy.

An ethnically diverse group of community dwelling older people were purposefully recruited from northern New Zealand. Interviews and focus groups were digitally recorded, transcribed verbatim, and analysed. Thirty-nine participants from 4 ethnic groups were recruited (mean 74 years; range 6191 years; Maori (7), South Asian (8), European (9), and Pasifika (15)). Most participants were taking CVD medication/s. Participants emphasized the benefits of medication and downplayed the harms; they did not want to take medication but felt compelled to; they trusted their doctor to know best regarding medication; and they believed their doctor wanted them to keep taking medication. Findings raise questions about older people's agency in decision-making regarding medication. Work is needed to identify strategies to support effective communication of the potential benefits and harms of medication in older people, balancing life expectancy, and the expected duration of therapy.

Balance disorders are caused by several factors related to functionality deficits in one or multiple sensory systems such as vision, vestibular, and somatosensory systems. Patients usually have difficulty explaining their dizziness, often using ambiguous words to describe their symptoms. A common practice by clinicians is to objectively evaluate the patient's dizziness by applying the Sensory Organization Test (SOT), which measures the contribution of each sensory system (vestibular, visual, somatosensory). The SOT protocol can record up to 2000 measurements in 20 s to generate the Equilibrium Score (EQS) with its five load sensors. EQS is an indicator that reflects how well a patient can maintain balance. However, its calculation only considers two instances from these 2000 measurements that reflect the maximum anterior and posterior sway angle during the test performance; therefore, there is an opportunity to perform further analysis. This article aims to use the Centre of Pressure (COP) time series generated by the SOT and describes a methodology to pre-process and reduce the dimensionality of this raw data and use it as an input for machine learning algorithms to diagnose patients with balance disorder impairments. After applying this methodology to data from 475 patients, the logistic regression model (LR) produced the highest f1-score with 76.47%, and the support vector machine (SVM) performed almost as well, with an f1-score of 76.19%.

Advances in technology provide an opportunity to enhance the accuracy of gait and balance assessment, improving the diagnosis and rehabilitation processes for people with acute or chronic health conditions. This study investigated the validity and reliability of a smartphone-based application to measure postural stability and spatiotemporal aspects of gait during four static balance and two gait tasks. Thirty healthy participants (aged 20-69 years) performed the following tasks: (1) standing on a firm surface with eyes opened, (2) standing on a firm surface with eyes closed, (3) standing on a compliant surface with eyes open, (4) standing on a compliant surface with eyes closed, (5) walking in a straight line, and (6) walking in a straight line while turning their head from side to side. During these tasks, the app quantified the participants' postural stability and spatiotemporal gait parameters. The concurrent validity of the smartphone app with respect to a 3D motion capture system was evaluated using partial Pearson's correlations (rp) and limits of the agreement (LoA%). The within-session test-retest reliability over three repeated measures was assessed with the intraclass correlation coefficient (ICC) and the standard error of measurement (SEM). One-way repeated measures analyses of variance (ANOVAs) were used to evaluate responsiveness to differences across tasks and repetitions. Periodicity index, step length, step time, and walking speed during the gait tasks and postural stability outcomes during the static tasks showed moderate-to-excellent validity (0.55 ≤ rp ≤ 0.98; 3% ≤ LoA% ≤ 12%) and reliability scores (0.52 ≤ ICC ≤ 0.92; 1% ≤ SEM% ≤ 6%) when the repetition effect was removed. Conversely, step variability and asymmetry parameters during both gait tasks generally showed poor validity and reliability except step length asymmetry, which showed moderate reliability (0.53 ≤ ICC ≤ 0.62) in both tasks when the repetition effect was removed. Postural stability and spatiotemporal gait parameters were found responsive (p < 0.05) to differences across tasks and test repetitions. Along with sound clinical judgement, the app can potentially be used in clinical practice to detect gait and balance impairments and track the effectiveness of rehabilitation programs. Further evaluation and refinement of the app in people with significant gait and balance deficits is needed.

INTRODUCTION: Hospitalization and post-discharge provide an opportune time for tobacco cessation. This study tested the feasibility, uptake, and cessation outcomes of a hospital-based tobacco cessation program, delivered by volunteers to the bedside with post-discharge referral to Quitline services. Patient characteristics associated with Quitline uptake and cessation were assessed. METHODS: Between February and November 2016, trained hospital volunteers approached inpatient tobacco users on six pilot units. Volunteers shared a cessation brochure and used the ASK-ADVISE-CONNECT model to connect ready to quit patients to the Delaware Quitline via fax-referral. Volunteers administered a follow-up survey to all admitted tobacco users via telephone or email at 3-months post-discharge. RESULTS: Of the 743 admitted tobacco users, 531 (72%) were visited by a volunteer, and 97% (531/547) of those approached, accepted the visit. Over one-third (201/531; 38%) were ready to quit and fax-referred to the Quitline, and 36% of those referred accepted Quitline services. At 3 months post-discharge, 37% (135/368) reported not using tobacco in the last 30 days; intent-to-treat cessation rate was 18% (135/743). In a multivariable regression model of Quitline fax-referral completion, receiving nicotine replacement therapy (NRT) during hospitalization was the strongest predictor (odds ratios [OR] = 1.97; 95% confidence interval [CI] = 1.34 to 2.90). In a model of 3-month cessation, receiving Quitline services (OR = 3.21, 95% CI = 1.35 to 7.68) and having coronary artery disease (OR = 2.28; 95% CI = 1.11 to 4.68) were associated with tobacco cessation, but a volunteer visit was not. CONCLUSIONS: An "opt-out" tobacco cessation service using trained volunteers is feasible for connecting patients to Quitline services. IMPLICATIONS: This study demonstrates the feasibility of a systems-based approach to link inpatients to evidence-based treatment for tobacco use. This model used trained bedside volunteers to connect inpatients to a state-funded Quitline after discharge that offers free cessation treatment of telephone coaching and cessation medications. Receiving NRT during hospitalization positively impacted Quitline referral, and engagement with Quitline resources was critical to tobacco abstinence post-discharge. Future work is needed to evaluate the cost-effectiveness and sustainability of this volunteer model.

Event related potentials (ERPs) provide insight into the neural activity generated in response to motor, sensory and cognitive processes. Despite the increasing use of ERP data in clinical research little is known about the reliability of human manual ERP labelling methods. Intra-rater and inter-rater reliability were evaluated in five electroencephalography (EEG) experts who labelled the peak negativity of averaged movement related cortical potentials (MRCPs) derived from thirty datasets. Each dataset contained 50 MRCP epochs from healthy people performing cued voluntary or imagined movement, or people with stroke performing cued voluntary movement. Reliability was assessed using the intraclass correlation coefficient and standard error of measurement. Excellent intra- and inter-rater reliability was demonstrated in the voluntary movement conditions in healthy people and people with stroke. In comparison reliability in the imagined condition was low to moderate. Post-hoc secondary epoch analysis revealed that the morphology of the signal contributed to the consistency of epoch inclusion; potentially explaining the differences in reliability seen across conditions. Findings from this study may inform future research focused on developing automated labelling methods for ERP feature extraction and call to the wider community of researchers interested in utilizing ERPs as a measure of neurophysiological change or in the delivery of EEG-driven interventions.

OBJECTIVE: To assess the feasibility of conducting a randomized controlled trial of an instructional and educational stroke DVD and determine the feasibility and preliminary efficacy of this intervention in a multinational context. DESIGN: Non-funded, pilot randomized controlled trial of intervention versus usual care. SETTING: International, multicentre, community-based. PARTICIPANTS: Community-living adults up to three years post stroke with moderate to severe disability and their nominated informal caregivers. INTERVENTIONS: Intervention patients viewed and practised rehabilitation techniques demonstrated in the DVD over six weeks. MAIN MEASURES: Trial feasibility by number of active recruitment sites, recruitment efficiency, randomization and follow-up. Intervention feasibility by patient and caregiver impressions. Preliminary efficacy by the quality of life - 5-level EuroQol-5D (EQ-5D) health status measure, General Health Questionnaire and Centre for Epidemiological Studies-Depression at two months. RESULTS: In total, 14 recruitment sites were established across eight countries. Recruitment was achieved at nine (64%) sites. Over 16 months, 66 participants were recruited (mean (SD) age = 63.5 (12.47) years) and randomized to intervention ( n = 34) and control ( n = 32) groups. In total, 54 (82%) completed a follow-up assessment. Patient and/or caregiver comments about the benefits and barriers to accessing the intervention were mixed. There were no significant between-group differences in outcomes at two months ( P > 0.05). CONCLUSION: Conducting a multinational trial of a stroke DVD requires full funding. The intervention was acceptable to some patients and their caregivers, yet a generalized education approach did not fully meet their needs and/or expectations. A more individualized method may be required to meet peoples' changing needs during stroke recovery.

Texas Instruments ADS1299 is an attractive choice for low cost electroencephalography (EEG) devices owing to its low power consumption and low input referred noise. To date, there have been no rigorous evaluations of its performance. In this EEG experimental study we evaluated the performance of the ADS1299 against a high quality laboratory-based system. Two self-paced lower limb motor tasks were performed by 22 healthy participants. Recorded power across delta, theta, alpha, and beta EEG bands, the power ratio across the motor tasks, pre-movement noise, and signal-to-noise ratio were obtained for evaluation. The amplitude and time of the negative peak in the movement-related cortical potentials (MRCPs) extracted from the EEG data were also obtained. Using linear mixed models, no statistically significant differences (p > 0.05) were found in any of these measures across the two systems. These findings were further supported by evaluation of cosine similarity, waveform differences, and topographic maps. There were statistically significant differences in MRCPs across the motor tasks in both systems. We conclude that the performance of the ADS1299 in combination with wet Ag/AgCl electrodes is analogous to that of a laboratory-based system in a low frequency (<40 Hz) EEG recording.
RESUMO
BACKGROUND: Novel paired associative stimulation (novel-PAS), delivered by pairing movement-related cortical potentials (MRCPs) with electrical stimulation of somatosensory afferents, is an innovative neuromodulatory intervention. Novel-PAS results in increased corticomotor excitability and has potential as a rehabilitative adjunct to improve outcomes following stroke. The duration of its excitatory effect has important implications for how this novel PAS intervention might be applied within a traditional therapy session, but previous research has not explored its effects beyond 30 min post-intervention. OBJECTIVE: The objective was to explore changes in corticomotor excitability in healthy participants, over a 60-min period following a single session of novel-PAS. MATERIALS AND METHOD: Ten healthy adults completed a single session of novel-PAS, delivered by pairing 50 MRCPs with peripheral electrical stimulation. TMS was used to elicit motor evoked potentials (MEPs) of the tibialis anterior (TA) muscle, immediately prior to the intervention, and at 0, 30, 45, and 60 min post-intervention. RESULTS: When compared with pre-intervention, there was a statistically significant increase in the mean TA MEP amplitudes at 0 (p = 0.006), 30 (p = 0.006), 45 (p = 0.027), and 60 min post-intervention (p = 0.020). CONCLUSION: Corticomotor excitability is increased for 60 min following this novel-PAS intervention. Future research could investigate the optimal method of combining this neuromodulatory technique with traditional therapy.

We examined the benefits of a collaboration between the Indian Health Service and an academic medical center to address the high rates of unintentional drug overdose in American Indians/Alaska Natives. In January 2015, the Indian Health Service became the first federal agency to mandate training in pain and opioid substance use disorder for all prescribing clinicians. More than 1300 Indian Health Service clinicians were trained in 7 possible 5-hour courses specific to pain and addiction. We noted positive changes in pre- and postcourse knowledge, self-efficacy, and attitudes as well as thematic responses showing the trainings to be comprehensive, interactive, and convenient.

Textiles able to perform electronic functions are known as e-textiles, and are poised to revolutionise the manner in which rehabilitation and assistive technology is provided. With numerous reports in mainstream media of the possibilities and promise of e-textiles it is timely to review research work in this area related to neurological rehabilitation.This paper provides a review based on a systematic search conducted using EBSCO- Health, Scopus, AMED, PEDro and ProQuest databases, complemented by articles sourced from reference lists. Articles were included if the e-textile technology described had the potential for use in neurological rehabilitation and had been trialled on human participants. A total of 108 records were identified and screened, with 20 meeting the broad review inclusion criteria. Nineteen user trials of healthy people and one pilot study with stroke participants have been reported.The review identifies two areas of research focus; motion sensing, and the measurement of, or stimulation of, muscle activity. In terms of motion sensing, E-textiles appear able to reliably measure gross movement and whether an individual has achieved a predetermined movement pattern. However, the technology still remains somewhat cumbersome and lacking in resolution at present. The measurement of muscle activity and the provision of functional electrical stimulation via e-textiles is in the initial stages of development but shows potential for e-textile expansion into assistive technologies.The review identified a lack of high quality clinical evidence and, in some cases, a lack of practicality for clinical application. These issues may be overcome by engagement of clinicians in e-textile research and using their expertise to develop products that augment and enhance neurological rehabilitation practice.

OBJECTIVES: To examine the association between the Gait Deviation Index (GDI), a multivariate measure of overall gait impairment, and measures of both community walking performance and walking capacity within the clinic setting in ambulatory children with cerebral palsy. DESIGN: Cross-sectional study. SETTING: Gait analysis, 6-minute walk test (6MWT), and self-selected walking speed (WS) were conducted in laboratory and clinic settings. Activity monitoring was done in participants' community environment. PARTICIPANTS: Children with cerebral palsy (N=55; age range, 6-18y) with Gross Motor Function Classification System levels I to III. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The GDI was derived from gait analysis data as a measure of overall gait impairment; an activity monitor was used to capture community walking performance, and the 6MWT and WS were the clinic-based measures of walking capacity. RESULTS: Fifty-five children had a median GDI of 78.86 (range, 53.07-105.34). A moderate association was found between the GDI and daily step count (Spearman ρ=.58; 95% confidence interval [CI], .37-.74; P<.0001). Weaker associations were found between the GDI and 6MWT (Spearman ρ=.4718; 95% CI, .2283-.6597; P<.0003) and between the GDI and WS (Spearman ρ=.3949; 95% CI, .1368-.6028; P<.0028). CONCLUSIONS: The GDI has a moderate association with daily step count, which suggests that interventions that positively change gait kinematics may also affect community walking performance. Although the GDI's deviation from the normal value provides valuable information, other measures are required to provide a complete picture of a child's walking capacity and performance.

AIM: To compare sole nurse and doctor-led multidisciplinary team delivery of community clozapine services for people with treatment-resistant schizophrenia. BACKGROUND: Around 20% of people with schizophrenia are treatment resistant and fail to respond to front line medications. Clozapine, a second-line treatment, has potentially serious side effects requiring regular monitoring. Different models of community clozapine services are emerging in the British National Health Service, but there is little evidence about which is best. DESIGN: Questionnaire survey of service users. METHODS: All patients on the lists of seven clozapine clinics (four sole nurse, three multidisciplinary team) in one trust were invited to participate, 2009-2010. Forward stepwise regression was used to investigate associations between patient well-being, functioning, self-efficacy and satisfaction, and clinic model attended, controlling for socio-demographic and health characteristics and processes of care. Use (and costs) of other health and social services accessed was compared between models. RESULTS: Sixty-six service users (35% participation rate) responded. Well-being and functioning were associated with patient characteristics and processes of care, not clinic model. Patients managed by sole nurses reported, over 3 months: more community psychiatric nurse visits and hospital psychiatrist appointments. Clinic list size affects costs per patient. CONCLUSIONS: Multidisciplinary team delivery may reduce use of other services. Although multidisciplinary team delivery is regarded as best practice, sole nurses can effectively provide clozapine services and may be warranted in areas of low population density.

Chronic pain and opioid addiction are 2 pressing public health problems, and prescribing clinicians often lack the skills necessary to manage these conditions. Our study sought to address the benefits of a coalition of an academic medical center pain faculty and government agencies in addressing the high unintentional overdose death rates in New Mexico. New Mexico's 2012-2013 mandated chronic pain and addiction education programs studied more than 1000 clinicians. Positive changes were noted in precourse and postcourse surveys of knowledge, self-efficacy, and attitudes. Controlled substance dispensing data from the New Mexico Board of Pharmacy also demonstrated safer prescribing. The total morphine and Valium milligram equivalents dispensed have decreased continually since 2011. There was also a concomitant decline in total drug overdose deaths.

There is evidence from high quality studies to strongly support the positive association between increased levels of physical activity, exercise participation and improved health in older adults. Worldwide, around 3.2 million deaths per year are being attributed to inactivity. In industrialised countries where people are living longer lives, the levels of chronic health conditions are increasing and the levels of physical activity are declining. Key factors in improving health are exercising at a moderate-to-vigorous level for at least 5 days per week and including both aerobic and strengthening exercises. Few older adults achieve the level of physical activity or exercise that accompanies health improvements. A challenge for health professionals is to increase physical activity and exercise participation in older adults. Some success in this has been reported when physicians have given specific, detailed and localised information to their patients, but more high quality research is needed to continue to address this issue of non-participation in physical activity and exercise of a high enough level to ensure health benefits.

Smartphone accelerometry has potential to provide clinicians with specialized gait analysis not available in most clinical settings. The Gait&Balance Application (G&B App) uses smartphone accelerometry to assess spatiotemporal gait parameters under two conditions: walking looking straight ahead and walking with horizontal head turns. This study investigated the validity of G&B App gait parameters compared with the GAITRite® pressure-sensitive walkway. Healthy young and older adults (age range 21-85 years) attended a single session where a smartphone was secured over the lumbosacral junction. Data were collected concurrently with the app and GAITRite® systems as participants completed the two walking conditions. Spatiotemporal gait parameters for 54 participants were determined from both systems and agreement evaluated with partial Pearson's correlation coefficients and limits of agreement. The results demonstrated moderate to excellent validity for G&B App measures of step time (rp 0.97, 95 % CI [0.96, 0.98]), walking speed (rp 0.83 [0.78, 0.87]), and step length (rp 0.74, [0.66, 0.80]) when walking looking straight ahead, and results were comparable with head turns. The validity of walking speed and step length measures was influenced by sex and height. G&B App measures of step length variability, step time variability, step length asymmetry, and step time asymmetry had poor validity. The G&B App has potential to provide valid measures of unilateral and bilateral step time, unilateral and bilateral step length, and walking speed, under two walking conditions in healthy young and older adults. Further research should validate this tool in clinical conditions and optimise the algorithm for demographic characteristics.

This study investigates how adding a cognitive task on a balance board (exergame) affects connectivity in the dorsal attention network (DAN) during an exergame task. Healthy young adults performed a soccer ball-moving task by tilting a balance board with their feet while their brain activity was measured using electroencephalography (EEG). In this exergame, the speed of obstacles in front of the goal manipulated the cognitive workload. Higher speed means a higher cognitive workload. The study found significant changes in functional connectivity within DAN regions, specifically in the alpha band. During the shift from easy to medium cognitive task, we observed a significant increase in connectivity (p= 0.0436) between the right inferior temporal (ITG R) and the Left middle temporal (MTG L). During the transition from easy to hard cognitive tasks, strengthened interactions (p= 0.0324) between inferior temporal (ITG) and parsopercularis (pOPPER) were found. This suggests that the proposed balanceboard-based exergame enhances the functionality of specific brain regions, such as ITG and MTG regions, and improves connectivity in the frontal cortex. We also found a correlation between brain activity and performance data, highlighting that increased cognitive workload resulted in decreased performance and heightened frontal alpha activity. These findings align with research suggesting that adding cognitive games to physical activity-based tasks in rehabilitation programs can boost brain activity, resulting in improved decision-making and visual processing skills. This information can help clinicians tailor rehabilitation methods that target specific brain regions.

OBJECTIVES: To investigate the effect of an exercise program on falls in intermediate and high-level long-term care (LTC) residents and to determine whether adherence, physical capacity, and cognition modified outcomes. DESIGN: Randomized controlled trial. SETTING AND PARTICIPANTS: Residents (n = 520, aged 84 ± 8 years) from 25 LTC facilities in New Zealand. METHODS: Individually randomized to Staying UpRight, a physical therapist-led, balance and strength group exercise program delivered for 1 hour, twice weekly over 12 months. The control arm was dose-matched and used seated activities with no resistance. Falls were collected using routinely collected incident reports. RESULTS: Baseline fall rates were 4.1 and 3.3 falls per person-year (ppy) for intervention and control groups. Fall rates over the trial period were 4.1 and 4.3 falls ppy respectively [P = .89, incidence rate ratio (IRR) 0.98, 95% CI 0.76, 1.27]. Over the 12-month trial period, 74% fell, with 63% of intervention and 61% of the control group falling more than once. Risk of falls (P = .56, hazard ratio 1.08, 95% CI 0.85, 1.36) and repeat falling or fallers sustaining an injury at trial completion were similar between groups. Fall rates per 100 hours walked did not differ between groups (P = .42, IRR 1.15, 95% CI 0.81, 1.63). Program delivery was suspended several times because of COVID-19, reducing average attendance to 26 hours over 12 months. Subgroup analyses of falls outcomes for those with the highest attendance (≥50% of classes), better physical capacity (Short Physical Performance Battery scores ≥8/12), or cognition (Montreal Cognitive Assessment scores ≥ 18/30) showed no significant impact of the program. CONCLUSIONS/IMPLICATIONS: In intermediate and high-level care residents, the Staying UpRight program did not reduce fall rates or risk compared with a control activity, independent of age, sex, or care level. Inadequate exercise dose because of COVID-19-related interruptions to intervention delivery likely contributed to the null result.
