The rollator is a mobility aid commonly used to facilitate balance and mobility for individuals with cardiorespiratory, musculoskeletal, or neurological deficits. Despite its popularity, there are also reports of adverse effects related to walker use linked to increased fall risks. Studies examining the effectiveness and consequences of rollator use have employed standard laboratory-based measurement methods that rely on performing specific tasks within a short time period and under controlled conditions, potentially limiting generalization to mobility in the everyday context. An instrumented rolling walker (iWalker) was developed as an ambulatory measurement tool applicable to the assessment of balance outside of the lab or clinic for assistive device users. The iWalker autonomously collects measurements of the upper and lower limb behaviour related to balance, walker kinematics, and video of the immediate spatial environment. The design and development of the iWalker is first described, followed by two studies characterizing the involvement of the upper limbs for balance in standing and walking that served to address gaps in the literature and evaluate the utility of the upper limb measures. Overall, the upper limbs can become the primary effectors of balancing forces when lower limb capabilities are compromised. When lower limb involvement was experimentally constrained, the upper limbs became the primary effectors of balance control in healthy, young adults. In older adults, individuals demonstrating the highest upper limb usage during walking were associated with the largest reduction in frontal plane stepping parameters (i.e., step width). A third study evaluated the applicability of the iWalker to assess everyday mobility in a series of in-patients recovering from neurological injury (i.e., stroke, traumatic brain injury). Patients demonstrated significantly different upper limb balancing behaviour in everyday situations compared to in-laboratory assessments. Furthermore, the iWalker captured behaviours that may be precursors to falling, such as collisions, stumbling and lifting the assistive device. The implications of these studies on assessing the effectiveness of rollators and feasibility of using the iWalker in follow-up efforts are discussed.

Background: Stroke survivors often have persistent neural deficits related to motor function and sensation, which increase their risk of falling, most of which occurs at home or in community settings. The use of wearable technology to monitor fall risk and gait in stroke survivors may prove useful in enhancing recovery and/or preventing injuries. Objective: Determine the feasibility of using wearable technology (PAMSys (TM)) to objectively monitor fall risk and gait in home and community settings in stroke survivors. Methods: In this feasibility study, we used the PAMSys to identify fall risk indicators (postural transitions: duration in seconds, and number of unsuccessful attempts), and gait (steps, speed, duration) for 48 hours during usual daily activities in stroke survivors (n=10) compared to age-matched controls (n=10). A questionnaire assessed device acceptability. Results: Stroke survivors mean age was 70 +/- 8 years old, were mainly Caucasian (60%) women (70%), and not significantly different than the age-matched controls (all P-values >0.20). Stroke survivors (100%) reported that the device was comfortable to wear, didn't interfere with everyday activities, and were willing to wear it for another 48 hours. None reported any difficulty with the device while sleeping, removing/putting back on for showering or changing clothes. When compared to controls, stroke survivors had significantly worse fall risk indicators and walked less (P<0.05). Conclusion: Stroke survivors reported high acceptability of 48 hours of continuous PAMSys monitoring. The use of in-home wearable technology may prove useful in monitoring fall risk and gait in stroke survivors, potentially enhancing recovery.

Class of 2006 Abstract / Objectives: To determine the effectiveness of etanercept therapy on C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), height, weight and body mass index (BMI) of patients with juvenile rheumatoid arthritis in an ambulatory pediatric clinic. Methods: This project used a pretest-posttest design that assessed patients before treatment with etanercept and then 6 months after the treatment was begun. Pre-treatment and post-treatment data were obtained through a retrospective chart review. A chart review was performed to collect each patient’s ESR, CRP, height, weight, BMI, and demographic data using a standardized data collection instrument. A paired t-test was performed to compare the pre-treatment and post-treatment data for the ESR, CRP, height, weight and BMI measurements. Results: Nine patients were identified that met the study inclusion. The mean age (SD) of the patients was 13.1 (4.4) years. Increases in weight and height parameters were seen after 6 months of etanercept treatment (p= 0.05, 0.002, respectively). There were no differences found in BMI, CRP and ESR parameters (p= 0.133, 0.753, 0.188, respectively) between the pre and post measurements. Conclusions: This pre-post analysis of 9 patients with juvenile rheumatoid arthritis found that etanercept therapy was associated with a significant gain in weight and height. However, this study found no differences in CRP or ESR after etanercept treatment. Additional research in larger populations is needed to more fully describe the changes in monitoring parameters following etanercept therapy.

Dissertation submitted to the Faculty of Health Sciences, University of Witwatersrand in fulfillment of the Master of Science in Medicine in the School of Physiology / Introduction: The changing socio-economic landscape in Africa has brought with it unique health challenges previously uncommon in people of African ancestry. Noncommunicable diseases such as coronary artery disease and stroke have emerged as pressing public health concern highlighting the need to find more on-target diagnostic tools as well as therapeutic interventions. Although ambulatory blood pressure (AMBP) has in many studies conducted in the western world proved to be an independent predictor of carotid intima-media thickness (C-IMT), such results cannot outright be imputed to people of African ancestry living in Africa. That is because people of African ancestry living in Africa are not only of a different ethnicity but are still in the early phases of an epidemiological transition while people in the western countries who are mostly Caucasians, are believed to be in the middle to late phases of an epidemiological transition. Methods: The relationship between the intima-media thickness of the common carotid artery (SonoCalcTM IMT version 3.4) and AMBP (Space labs model 90207) was determined in 320 randomly selected participants of African descent living in an urban developing community in South Africa. Relationships were determined after adjustment for (clinic blood pressure) BPc, age, gender, alcohol and tobacco use, the presence or absence of diabetes mellitus or inappropriate blood glucose control measured by glycated hemoglobin (ghb), antihypertensive therapy and menopausal status. III Results: Mean age for the study population was 43.7± 16.0 years. Both BPc and AMBP parameters were strongly associated with C-IMT (p<0.001) in univariate analysis. In multivariate analysis with BPc. and AMBP entered into separate models and after adjusting for cofounders, BPc. and AMBP maintained significant associations with CIMT. [BPc (partial r=0.0648, p< 0.1612), systolic blood pressure 24 (SBP24) (partial r= 0.236, p< 0.001), systolic blood pressure day (SBPd) (partial r= 0.302, p<0.05), systolic blood pressure night (SBPn) (partial r= 0.0983, p<0.05)]. When adjustments were made with BPc. and SBP24 entered into the same model, BPc lost its association with C-IMT, [SBP24 (partial r=0.236, p<0.001) SBPd (partial r=0.149, p<0.05), SBPn (partial r=0.172, p<0.05)]. Importantly the relationship between SBP24 and C-IMT persisted independent of body mass index (BMI), BPc and age. SBP24 had the highest significant association with C-IMT. Conclusion: SBP24 independently predicts C-IMT even in a model that includes conventional systolic blood pressure (SBPc) leading to the conclusion that AMBP is a more effective tool at diagnosing C-IMT alterations while BPcdoes not have an independent relationship C-IMT.

This article reviews the Electronically Activated Recorder (EAR) as an ambulatory ecological momentary assessment tool for the real-world observation of daily behavior. Technically, the EAR is an audio recorder that intermittently records snippets of ambient sounds while participants go about their lives. Conceptually, it is a naturalistic observation method that yields an acoustic log of a person’s day as it unfolds. The power of the EAR lies in unobtrusively collecting authentic real-life observational data. In preserving a high degree of naturalism at the level of the raw recordings, it resembles ethnographic methods; through its sampling and coding, it enables larger empirical studies. This article provides an overview of the EAR method; reviews its validity, utility, and limitations; and discusses it in the context of current developments in ambulatory assessment, specifically the emerging field of mobile sensing.

The purpose of this study was to determine the indicators of customer satisfaction and service success of a newly established paediatric outreach nursing service. Referring agents and care recipients were both consumers of the paediatric outreach nursing service. Both groups of consumers were surveyed to determine their satisfaction with the service delivery. Two satisfaction survey tools were developed to measure customer satisfaction. The tools were piloted and refined prior to distributing them. Both tools had a series of closed-ended questions and 3 open-ended questions. Eight service indicators were developed. These were designed to test the effectiveness of the service provided. The service indicators were piloted over two periods of three months and then modified based on the findings of the pilot period. The Paediatric Outreach Service (POS) is a positive service model for health care delivery. The survey results indicated that stakeholders were generally satisfied with the service delivery. When measured against service indicators that were developed for POS, the service performance was above average, with some opportunity to improve practice. Underpinned by a family-centered framework, POS has the capacity to empower children and their families in the planning and implementation of a management plan for the child’s illness. Such empowerment may lead families to practice better healthcare, develop better health-seeking practices and ultimately lead to healthier children. The results from this study has implications for nursing practice. The data obtained from this study may be useful to service providers considering commencing a paediatric outreach nursing service. Data may also be useful for existing service providers to use in order to review the aspects that consumers value against the service they currently provide.

Syfte: Att beskriva dagkirurgiska patienters upplevelse av att bli utskrivna hem samma dag efter operation utförd i generell anestesi. Metod: Kvalitativ intervjustudie med induktiv ansats. Elva patienter som har opererats via en handkirurgisk mottagning i mellersta Sverige har intervjuats utifrån en semistrukturerad intervjuguide. Sju kvinnor och fyra män i åldrarna mellan 28-71 år har deltagit i studien. Innehållsanalys användes för analys av materialet. Resultat: Patienterna upplevde hemgången som väldigt positiv. De faktorer som bidrog till en lyckad hemgång var framförallt; Patientens goda grundhälsa, en trygg hemmiljö att återvända till och återhämta sig i, samt att patienterna får sina frågor och funderingar besvarade inför hemgången, och stöd från anhöriga. Vårdpersonalens bemötande och professionella förhållningssätt bidrog till att patienterna upplevde en känsla av trygghet som skapade en förutsättning för delaktighet.  Resultatet visar även att patienter önskar mer information om det postoperativa förloppet. Slutsats: Att skrivas ut och komma hem efter ett dagkirurgiskt ingrepp är en positiv upplevelse för patienterna, dock behöver informationen inför hemgången samt möjligheten till stöd från den dagkirurgiska enheten efter hemgången förbättras. / Aim: To describe the day-surgery patients´ experience to be discharge the same day after surgery in general anesthesia. Methods: Qualitative interview study with inductive approach. Eleven patients, operated by a hand surgical receptions in central Sweden were interviewed, using a semi- structured interview guide. Seven women and four men between 28-71 years participated in the study. Content analysis was used for analysis of the material. Result: Patients experienced the discharge as very positive. The factors which contributed to a successful discharge was above all, patient good basic health, a safe home to return to and recover in, and that the patients have their questions and concerns answered before discharge, and the support from relatives. Health professionals' reception and professional approach helped the patients to feel a sense of security that created a condition for participation. The results also show that patients want more information about the postoperative recovery. Conclusions: To be discharged, and come home, after day surgery procedures is a positive experience for patients, however, the information at discharge and the possibility of support from the day surgery unit after discharge needs to improve.
