Analysis of ankle muscle activity: A study on static balance with eyes closed and high-heeled shoes.

BACKGROUND: Changes in sensory afferent interfere with the control of postural stability by the central nervous system. Wearing high-heeled shoes is an example of an external disturbance that changes sensory inputs and results in several postural adjustments to control stability. Thus, our purpose is to investigate the influence of high-heeled shoes and visual absence on maintenance of static balance and on ankle muscle activity among young women. Our hypothesis is that the combination of high-heeled shoes with visual absence lead to an increase of postural sway and of levels of activation of the stabilizing ankle muscles. METHODS: Nine volunteers remained in an unrestrained erect posture on a force platform for collecting of stabilometric and electromyographic parameters in four bipodal conditions: barefoot with open eyes, barefoot with closed eyes, with high heels and open eyes and with high heels and closed eyes. RESULTS: When comparing the experimental condition open and closed eyes with high heels, there were significant differences for all stabilometric variables, except for the confidence ellipse area. Statistical differences were found for the medial gastrocnemius muscle in all comparison pairs with high heels. CONCLUSION: The wearing high-heeled shoes showed to be the most influencing disturbance on static balance. Our findings suggest ankle muscle activity is adapted according to changes of the center of pressure sway and the wearing of high heels changes the muscle activation and postural sway.

Cultivating leaders for primary health care: A revised approach for transformative development.

Family physicians require leadership skills to strengthen team-based primary care services. Interviews with South African district managers confirmed the need to develop leadership skills in family physicians. The updated national programmatic learning outcomes for South African family physician training were published in 2021. They sparked the need for curriculum renewal at the University of Cape Town's Division of Family Medicine. A review of the leadership and governance module during registrar training showed that the sessions were perceived to be content heavy with insufficient opportunities for reflection. Following a series of stakeholder engagements, the module convenors co-designed a revised module that was blueprinted on the updated learning outcomes. The module incorporates a group coaching style, facilitating learning through reflection on one's experiences. The revised module was implemented in 2022. It aims to provide a transformative learning experience centred on students' perceptions of themselves as leaders, as well as professional identity formation and resilience building. This short report describes preliminary insights from the revised module's developmental phase and forms part of an ongoing iterative evaluation process.Contribution: Family physicians should lead across all their defined roles. Formal and informal learning opportunities are needed to facilitate their growth as leaders and help them to meet the health needs of communities served by an evolving health care system. This short report describes an example of a revised postgraduate module on leadership and governance, which may be of value to clinician educators and academic departments exploring innovative methods for the African region.

RehaBEElitation: the architecture and organization of a serious game to evaluate motor signs in Parkinson's disease.

Background: The use of serious games (SG) has received increasing attention in health care, and can be applied for both rehabilitation and evaluation of motor signs of several diseases, such as Parkinson's disease (PD). However, the use of these instruments in clinical practice is poorly observed, since there is a scarcity of games that, during their development process, simultaneously address issues of usability and architectural design, contributing to the non-satisfaction of the actual needs of professionals and patients. Thus, this study aimed to present the architecture and usability evaluation at the design stage of a serious game, so-called RehaBEElitation, and assess the accessibility of the game. Methods: The game was created by a multidisciplinary team with experience in game development and PD, taking into consideration design guidelines for the development of SG. The user must control the movements of a bee in a 3D environment. The game tasks were designed to mimic the following movements found in the gold-standard method tool-Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS)-for the assessment of individuals with PD: hand opening and closing, hand extension and flexion, hand adduction and abduction, finger tapping, and forearm supination and pronation. The user interacts with the game using a wearable interface device that embeds inertial and tactile sensors. The architecture of RehaBEElitation was detailed using the business process model (BPM) notation and the usability of the architecture was evaluated using the Nielsen-Shneiderman heuristics. Game accessibility was evaluated by comparing the overall scores of each phase between 15 healthy participants and 15 PD patients. The PD group interacted with the game in both the ON and OFF states. Results: The system was modularized in order to implement parallel, simultaneous and independent programming at different levels, requiring less computational effort and enabling fluidity between the game and the control of the interface elements in real time. The developed architecture allows the inclusion of new elements for patient status monitoring, extending the functionality of the tool without changing its fundamental characteristics. The heuristic evaluation contemplated all the 14 heuristics proposed by Shneiderman, which enabled the implementation of improvements in the game. The evaluation of accessibility revealed no statistically significant differences (p < 0.05) between groups, except for the healthy group and the PD group in the OFF state of medication during Phase 3 of the game. Conclusions: The proposed architecture was presented in order to facilitate the reproduction of the system and extend its application to other scenarios. In the same way, the heuristic evaluation performed can serve as a contribution to the advancement of the SG design for PD. The accessibility evaluation revealed that the game is accessible to individuals with PD.

Wrist Rigidity Evaluation in Parkinson's Disease: A Scoping Review.

(1) Background: One of the main cardinal signs of Parkinson's disease (PD) is rigidity, whose assessment is important for monitoring the patient's recovery. The wrist is one of the joints most affected by this symptom, which has a great impact on activities of daily living and consequently on quality of life. The assessment of rigidity is traditionally made by clinical scales, which have limitations due to their subjectivity and low intra- and inter-examiner reliability. (2) Objectives: To compile the main methods used to assess wrist rigidity in PD and to study their validity and reliability, a scope review was conducted. (3) Methods: PubMed, IEEE/IET Electronic Library, Web of Science, Scopus, Cochrane, Bireme, Google Scholar and Science Direct databases were used. (4) Results: Twenty-eight studies were included. The studies presented several methods for quantitative assessment of rigidity using instruments such as force and inertial sensors. (5) Conclusions: Such methods present good correlation with clinical scales and are useful for detecting and monitoring rigidity. However, the development of a standard quantitative method for assessing rigidity in clinical practice remains a challenge.

No abstract available.

Non-communicable disease care and management in two sites of the Cape Town Metro during the first wave of COVID-19: A rapid appraisal.

BACKGROUND:  Non-communicable diseases (NCDs), including type-2 diabetes and hypertension, have been associated with increased morbidity and mortality rates because of coronavirus disease 2019 (COVID-19). Maintaining quality care for these conditions is important but data on the impact of COVID-19 on NCD care in South Africa are sparse. AIM:  This study aimed to assess the impact of COVID-19 on facility and community-based NCD care and management during the first COVID-19 wave. SETTING:  Two public health sector primary care sites in the Cape Town Metro, including a Community Orientated Primary Care (COPC) learning site. METHODS:  A rapid appraisal with convergent mixed-methods design, including semi-structured interviews with facility and community health workers (CHWs) (n = 20) and patients living with NCDs (n = 8), was used. Interviews were conducted in English and Afrikaans by qualified interviewers. Transcripts were analysed by thematic content analysis. Quantitative data of health facility attendance, chronic dispensing unit (CDU) prescriptions and routine diabetes control were sourced from the Provincial Health Data Centre and analysed descriptively. RESULTS:  Qualitative analysis revealed three themes: disruption (cancellation of services, fear of infection, stress and anxiety), service reorganisation (communication, home delivery of medication, CHW scope of work, risk stratification and change management) and outcomes (workload and morale, stigma, appreciation and impact on NCD control). There was a drop in primary care attendance and an increase in CDU prescriptions and uncontrolled diabetes. CONCLUSION:  This study described the service disruption together with rapid reorganisation and change management at primary care level during the first COVID-19 wave. The changes were strengthened by the COPC foundation in one of the study sites. The impact of COVID-19 on primary-level NCD care and management requires more investigation.

Two months follow-up of patients with non-critical COVID-19 in Cape Town, South Africa.

BACKGROUND: Approximately 10% of coronavirus disease 2019 (COVID-19) patients will experience long COVID. There is no study of long COVID in mild COVID-19 patients in South Africa. This study aimed, firstly, to describe the prevalence of long COVID in mild COVID-19 patients in Cape Town, and, secondly, to document the impact of COVID-19 on patients' well-being, work, and their access to long COVID treatment. METHODS: In this retrospective cross-sectional study, a random sample of adults diagnosed with mild COVID-19 were called two months post-diagnosis. The participants telephonically completed a standardised survey describing their long COVID symptoms, missed workdays, and health-seeking behaviour. Medical records were reviewed for comorbidities, original COVID-19 symptoms, and treatment. RESULTS: It was found that 60% of patients with mild COVID-19 had ≥ 1 long COVID symptom, while 35% had ≥ 3 ongoing symptoms for two months. Dyspnoea and fatigue were the most common symptoms. The findings revealed that 52% of employed patients missed work and 25% of patients self-reported non-recovery from their COVID-19. Moreover, 24% of patients consulted a clinician for long COVID, but only 7% of patients received long COVID care in the public sector. Of the 17% of patients requiring additional help for long COVID, 56% were interested in assistance by text message or telephonic consultation. CONCLUSION: Over a half of mild COVID-19 patients experienced at least one long COVID symptom for two months and nearly 20% needed additional medical treatment. Very few patients utilised the public sector for long COVID treatment. There is a great need for long COVID treatment in public healthcare services and patients are receptive to remote care.

Skills assessment metrics of electric powered wheelchair driving in a virtual environment: a survey.

The purpose of this review is to present studies on the parameters for assessing the skills of users of electric wheelchair driving simulators in a virtual environment. In addition, this study also aims to identify the most widely used and validated parameters for the quantification of electric wheelchair driving ability in a virtual environment and to suggest challenges for future research. To carry out this research, the criteria of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were adopted. Literature searches in English, French, and Portuguese were conducted up to December 2020 in the PubMed, SciELO, Science Direct, World Wide Science, and Scopus databases. The keywords used were electric wheelchair, simulator, performance indicators, performance skills, driving skills, training platform, virtual environment, and virtual reality. We excluded studies involving "real" wheelchairs without a simulator in a virtual environment. We have selected a total of 42 items. In these studies, we identified 32 parameters (3 qualitative and 29 quantitative) that are used as parameters for the evaluation of the ability to control a powered wheelchair in a virtual environment. Although the amount of research in this area has increased significantly in recent years, additional studies are still needed to provide a more accurate and objective assessment of skills among the target population. A challenge for future work is the increasing application of artificial intelligence techniques and the exploration of biomedical data measurements, which may be a promising alternative to improve the quantification of user competencies.

Reflections on epistemological aspects of artificial intelligence during the COVID-19 pandemic.

Artificial intelligence plays an important role and has been used by several countries as a health strategy in an attempt to understand, control and find a cure for the disease caused by Coronavirus. These intelligent systems can assist in accelerating the process of developing antivirals for Coronavirus and in predicting new variants of this virus. For this reason, much research on COVID-19 has been developed with the aim of contributing to new discoveries about the Coronavirus. However, there are some epistemological aspects about the use of AI in this pandemic period of Covid-19 that deserve to be discussed and need reflections. In this scenario, this article presents a reflection on the two epistemological aspects faced by the COVID-19 pandemic: (1) The epistemological aspect resulting from the use of patient data to fill the knowledge base of intelligent systems; (2) the epistemological problem arising from the dependence of health professionals on the results/diagnoses issued by intelligent systems. In addition, we present some epistemological challenges to be implemented in a pandemic period.

Development and validation of a tool to measure patient experience in chronic disease care.

BACKGROUND:  There is a global increase in the prevalence of non-communicable diseases and a growing understanding that patients need to be involved in their care. Patient experience should be assessed and the information used to improve on the planning and delivery of health services. AIM:  This study described the development and validation of a patient-reported experience measure (PREM) tool which is appropriate for the South African context, to assess self-reported patient experience of chronic care. SETTING:  The study was conducted at four primary health care facilities in the Cape Town Metropole. METHODS:  This was a validity and reliability study with multiple phases to develop and determine the psychometric properties of a novel tool. It consisted of three phases, namely: Phase 1 - Consensus Validity; Phase 2 - Face Validity; Phase 3 - Reliability. Phase 1 consisted of an expert panel reaching consensus on a draft tool. Phase 2a consisted of qualitative semi-structured interviews and cognitive interviews. Phase 3 tested the internal consistency of the tool, the time necessary to complete, as well as floor and ceiling effects with 200 questionnaires. RESULTS:  The process described resulted in a final questionnaire with n = 10 items in three languages that was easily understood by patients. Internal consistency was determined with the overall Cronbach's alpha 0.86. This PREM has been named Chronic Care Assessment of Patient Experience. CONCLUSION:  Using best practice guidance in tool construction and validation, we delivered a PREM with the potential to improve the quality of care from the perspective of patients. Implementation studies are now required to determine how best to use this tool in routine practice.

How to change organisational culture: Action research in a South African public sector primary care facility.

BACKGROUND: Organisational culture is a key factor in both patient and staff experience of the healthcare services. Patient satisfaction, staff engagement and performance are related to this experience. The department of health in the Western Cape espouses a values-based culture characterised by caring, competence, accountability, integrity, responsiveness and respect. However, transformation of the existing culture is required to achieve this vision. AIM: To explore how to transform the organisational culture in line with the desired values. SETTING: Retreat Community Health Centre, Cape Town, South Africa. METHODS: Participatory action research with the leadership engaged with action and reflection over a period of 18 months. Change in the organisational culture was measured at baseline and after 18 months by means of a cultural values assessment (CVA) survey. The three key leaders at the health centre also completed a 360-degree leadership values assessment (LVA) and had 6 months of coaching. RESULTS: Cultural entropy was reduced from 33 to 13% indicating significant transformation of organisational culture. The key driver of this transformation was change in the leadership style and functioning. Retreat health centre shifted from a culture that emphasised hierarchy, authority, command and control to one that established a greater sense of cohesion, shared vision, open communication, appreciation, respect, fairness and accountability. CONCLUSION: Transformation of organisational culture was possible through a participatory process that focused on the leadership style, communication and building relationships by means of CVA and feedback, 360-degree LVA, feedback and coaching and action learning in a co-operative inquiry group.

Auditing chronic disease care: Does it make a difference?

BACKGROUND: An integrated audit tool was developed for five chronic diseases, namely diabetes, hypertension, asthma, chronic obstructive pulmonary disease and epilepsy. Annual audits have been done in the Western Cape Metro district since 2009. The year 2012 was the first year that all six districts in South Africa's Western Cape Province participated in the audit process. AIM: To determine whether clinical audits improve chronic disease care in health districts over time. SETTING: Western Cape Province, South Africa. METHODS: Internal audits were conducted of primary healthcare facility processes and equipment availability as well as a folder review of 10 folders per chronic condition per facility. Random systematic sampling was used to select the 10 folders for the folder review. Combined data for all facilities gave a provincial overview and allowed for comparison between districts. Analysis was done comparing districts that have been participating in the audit process from 2009 to 2010 ('2012 old') to districts that started auditing recently ('2012 new'). RESULTS: The number of facilities audited has steadily increased from 29 in 2009 to 129 in 2012. Improvements between different years have been modest, and the overall provincial average seemed worse in 2012 compared to 2011. However, there was an improvement in the '2012 old' districts compared to the '2012 new' districts for both the facility audit and the folder review, including for eight clinical indicators, with '2012 new' districts being less likely to record clinical processes (OR 0.25, 95% CI 0.21-0.31). CONCLUSION: These findings are an indication of the value of audits to improve care processes over the long term. It is hoped that this improvement will lead to improved patient outcomes.

Clinical audit of diabetes management can improve the quality of care in a resource-limited primary care setting.

OBJECTIVE: To determine whether clinical audit improved the performance of diabetic clinical processes in the health district in which it was implemented. DESIGN: Patient folders were systematically sampled annually for review. SETTING: Primary health-care facilities in the Metro health district of the Western Cape Province in South Africa. PARTICIPANTS: Health-care workers involved in diabetes management. INTERVENTION: Clinical audit and feedback. MAIN OUTCOME MEASURE: The Skillings-Mack test was applied to median values of pooled audit results for nine diabetic clinical processes to measure whether there were statistically significant differences between annual audits performed in 2005, 2007, 2008 and 2009. Descriptive statistics were used to illustrate the order of values per process. RESULTS: A total of 40 community health centres participated in the baseline audit of 2005 that decreased to 30 in 2009. Except for two routine processes, baseline medians for six out of nine processes were below 50%. Pooled audit results showed statistically significant improvements in seven out of nine clinical processes. CONCLUSIONS: The findings indicate an association between the application of clinical audit and quality improvement in resource-limited settings. Co-interventions introduced after the baseline audit are likely to have contributed to improved outcomes. In addition, support from the relevant government health programmes and commitment of managers and frontline staff contributed to the audit's success.

General practitioners' perceptions on management of epilepsy in primary care settings in Cape Town, South Africa: an exploratory pilot study.

In a context where there are few neurologists, excellent management of patients with epilepsy at a primary care level is imperative. In South Africa, most uninsured patients suffering from epilepsy and other chronic illnesses are managed by general practitioners in state-provided primary care settings. We conducted a qualitative pilot study to explore perceptions of doctors working in primary care settings in Cape Town regarding the quality of epilepsy management. Our analysis revealed that these clinicians believe that epilepsy is poorly managed. Attributing factors were consistent with those found in literature. Although study findings cannot be generalized, we conclude that lack of attention to factors impacting on management of epilepsy is a serious concern and may lead to violations of health rights. Urgent prioritization, advocacy, collaboration, and empowerment of healthcare professionals, patients, lay carers, and the general public are needed to improve the management and quality of care of PWE.
