Wearable inertial sensors to measure gait and posture characteristic differences in older adult fallers and non-fallers: A scoping review

This is the final version. Available on open access from Elsevier via the DOI in this recordBackground Wearable inertial sensors have grown in popularity as a means of objectively assessing fall risk. This review aimed to identify gait and posture differences among older adult fallers and non-fallers which can be measured with the use of wearable inertial sensors. In addition to describing the number of sensors used to obtain measures, the concurrent anatomical locations, how these measures compare to current forms of clinical fall risk assessment tests and the setting of tests. Methods Following the development of a rigorous search strategy, MEDLINE, Web of Science, Cochrane, EMBASE, PEDro, and CINAHL were systematically searched for studies involving the use of wearable inertial sensors, to determine gait and postural based differences among fallers or those at high fall risk compared with non-fallers and low fall risk adults aged 60 years and older. Results Thirty five papers met the inclusion criteria. One hundred and forty nine gait and posture characteristic differences were identified using wearable inertial sensors. There were sensor derived measures which significantly and strongly correlated with traditional clinical tests. The use of a single wearable inertial sensor located at the lower posterior trunk, was most the most effective location and enough to ascertain multiple pertinent fall risk factors. Conclusion This review identified the capabilities of identifying fall risk factors among older adults with the use of wearable inertial sensors. The lightweight portable nature makes inertial sensors an effective tool to be implemented into clinical fall risk assessment and continuous unsupervised home monitoring, in addition to, outdoor testing.Engineering and Physical Sciences Research Council (EPSRC)National Institute for Health Research (NIHR

A scoping review comparing two common surgical approaches to the hip for hemiarthroplasty

This is the final version. Available from the publisher via the DOI in this record.Background: Hemiarthroplasty for hip fracture is a common surgical procedure. A number of distinct approaches are used to access the hip joint. The most commonly used are the direct lateral approach (DLA), and the posterior approach (PA). Internationally there is little consensus on which of these approaches to use. Current guidance is based on a limited selection of evidence and choice of approach is frequently based on surgeon preference. Historically, recommendations have been made based on dislocation rates. In light of technical advancements and greater recognition of patient priorities, outcomes such as post-operative function and pain may be considered more important in the modern context. The aim of this scoping review was to summarise the literature pertaining to the comparison of common surgical approaches to the hip for hemiarthroplasty. Methods: A scoping review methodology was used to examine the range and nature of primary research. Using systematic methods we searched for studies that directly compared the DLA and PA. Studies reporting the following outcomes were considered; dislocation, mortality, pain, activities of daily living, functionality, health-related quality of life, length of stay, surgeon assessment of difficulty, and adverse events. MEDLINE, EMBASE and The Cochrane Library were searched. Relevant information was extracted and synthesis of the retrieved data followed a basic content analytical approach. Results: A total of 13 studies were retrieved: 12 observational studies and 1 randomised trial. The majority of studies were based at single sites. Larger observational studies using multi-site and national registry data have emerged in recent years. Reporting of technique and outcomes is inconsistent. A trend for higher rates of dislocation using the PA was observed and eight studies recommended the use of the DLA over the PA. Conclusions: This scoping review demonstrates that the existing evidence is highly heterogeneous in nature and not of a sufficient quality to inform practice recommendations. This issue would be best addressed by additional RCTs, and high quality national-level observational data. Standardisation of the recording of patient risk factors, surgical and post-operative intervention protocols, and outcomes in all study designs would strengthen the potential for valid comparison of future findings.National Institute for Health Research (NIHR

Fundamental nursing care: a systematic review of the evidence on the effect of nursing care interventions for nutrition, elimination, mobility and hygiene

This is the final version of the article. Available from Wiley via the DOI in this record.AIMS AND OBJECTIVES: To determine the effects of nursing interventions for people's nutrition, elimination, mobility and hygiene needs. BACKGROUND: Patient experience of health care is sensitive to nursing quality. A refocus on fundamental nursing care is undermined by lack of evidence of effectiveness for interventions in core areas such as elimination, nutrition, mobility and hygiene. DESIGN: SYSTEMATIC REVIEW: METHODS: We searched for and included experimental studies on interventions by professionally qualified and unregistered nurses that addressed participants' nutrition, elimination, mobility and hygiene needs. We extracted data on scope, quality and results of studies followed by descriptive narrative synthesis of included study outcomes using a novel form of harvest plots. RESULTS: We included 149 studies, 35 nutrition, 56 elimination, 16 mobility, 39 hygiene, and three addressing two or more areas simultaneously (67 randomised controlled trials (RCTs), 32 non-RCTs and 50 uncontrolled trials). Studies into interventions on participant self-management of nutrition (n=25), oral health (n=26), catheter care (n=23), and self-management of elimination (n=21) were the most prevalent. Most studies focussed their outcomes on observational or physiological measures, with very few collecting patient reported outcomes, such as quality of life, experience or self-reported symptoms. All but 13 studies were of low quality and at significant risk of bias. The majority of studies did not define primary outcomes, included multiple measures of identical concepts, used inappropriate analyses, and did not conform to standard reporting quality criteria. CONCLUSIONS: The current evidence for fundamental nursing care interventions is sparse, of poor quality and unfit to provide evidence-based guidance to practising nurses.

Please cite the published version which is available via the DOI link in this record.Adherence is an important factor contributing to the effectiveness of exercise-based rehabilitation. However, there appears to be a lack of reliable, validated measures to assess self-reported adherence to prescribed but unsupervised home-based rehabilitation exercises.NIH

Creating psychological connections between intervention recipients: development and focus group evaluation of a group singing session for people with aphasia

This is the final version of the article. Available from BMJ Publishing Group via the DOI in this record.Objectives The study sought to identify key design features that could be used to create a new framework for group-based health interventions. We designed and tested the first session of a group intervention for stroke survivors with aphasia which was aimed at nurturing new psychological connections between group members. Setting The intervention session, a participant focus group and interviews with intervention facilitators were held in a local community music centre in the South West of England. Participants A convenience sample of 10 community-dwelling people with poststroke aphasia participated in the session. Severity of aphasia was not considered for inclusion. Intervention Participants took part in a 90-min group singing session which involved singing songs from a specially prepared song book. Musical accompaniment was provided by the facilitators. Primary and secondary outcome measures Participants and group facilitators reported their experiences of participating in the session, with a focus on activities within the session related to the intervention aims. Researcher observations of the session were also made. Results Two themes emerged from the analysis, concerning experiences of the session (‘developing a sense of group belonging’) and perceptions of its design and delivery (‘creating the conditions for engagement’). Participants described an emerging sense of shared social identity as a member of the intervention group and identified fixed (eg, group size, session breaks) and flexible (eg, facilitator responsiveness) features of the session which contributed to this emergence. Facilitator interviews and researcher observations corroborated and expanded participant reports. Conclusions Engagement with health intervention content may be enhanced in group settings when intervention participants begin to establish positive and meaningful psychological connections with other group members. Understanding and actively nurturing these connections should be a core feature of a general framework for the design and delivery of group interventions.This research was funded by the National Institute for Health Research (NIHR) Collaboration for Leadership in Applied Health Research and Care South West Peninsula.

Informing the design of a randomised controlled trial of an exercise-based programme for long term stroke survivors: lessons from a before-and-after case series study

Background: To inform the design of a randomised controlled trial (RCT) of an exercise-based programme for long term stroke survivors, we conducted a mixed methods before-and-after case series with assessment at three time points. We evaluated Action for Rehabilitation from Neurological Injury (ARNI), a personalised, functionally-focussed programme. It was delivered through 24 hours of one-to-one training by an Exercise Professional (EP), plus at least 2 hours weekly unsupervised exercise, over 12- 14 weeks. Assessment was by patient-rated questionnaires addressing function, physical activity, confidence, fatigue and health-related quality of life; objective assessment of gait quality and speed; qualitative individual interviews conducted with participants. Data were collected at baseline, 3 months and 6 months. Fidelity and acceptability was assessed by participant interviews, audit of participant and EP records, and observation of training. Findings: Four of six enrolled participants completed the exercise programme. Quantitative data demonstrated little change across the sample, but marked changes on some measures for some individuals. Qualitative interviews suggested that small benefits in physical outcomes could be of great psychological significance to participants. Participant-reported fatigue levels commonly increased, and non-completers said they found the programme too demanding. Most key components of the intervention were delivered, but there were several potentially important departures from intervention fidelity. Discussion: The study provided data and experience that are helping to inform the design of an RCT of this intervention. It suggested the need for a broader recruitment strategy; indicated areas that could be explored in more depth in the qualitative component of the trial; and highlighted issues that should be addressed to enhance and evaluate fidelity, particularly in the preparation and monitoring of intervention providers. The experience illustrates the value of even small sample before-and-after studies in the development of trials of complex interventions.PenCLAHRC; NIH

Multiple component interventions for preventing falls and fall-related injuries among older people: systematic review and meta-analysis

BACKGROUND: Limited attention has been paid in the literature to multiple component fall prevention interventions that comprise two or more fixed combinations of fall prevention interventions that are not individually tailored following a risk assessment. The study objective was to determine the effect of multiple component interventions on fall rates, number of fallers and fall-related injuries among older people and to establish effect sizes of particular intervention combinations. METHODS: Medline, EMBASE, CINAHL, PsychInfo, Cochrane, AMED, UK Clinical Research Network Study Portfolio, Current Controlled Trials register and Australian and New Zealand Clinical Trials register were systematically searched to August 2013 for randomised controlled trials targeting those aged 60 years and older with any medical condition or in any setting that compared multiple component interventions with no intervention, placebo or usual clinical care on the outcomes reported falls, number that fall or fall-related injuries. Included studies were appraised using the Cochrane risk of bias tool. Estimates of fall rate ratio and risk ratio were pooled across studies using random effects meta-analysis. Data synthesis took place in 2013. RESULTS: Eighteen papers reporting 17 trials were included (5034 participants). There was a reduction in the number of people that fell (pooled risk ratio = 0.85, 95% confidence interval (95% CI) 0.80 to 0.91) and the fall rate (pooled rate ratio = 0.80, 95% CI 0.72 to 0.89) in favour of multiple component interventions when compared with controls. There was a small amount of statistical heterogeneity (I(2) =20%) across studies for fall rate and no heterogeneity across studies examining number of people that fell. CONCLUSIONS: This systematic review and meta-analysis of randomised controlled trials found evidence that multiple component interventions that are not tailored to individually assessed risk factors are effective at reducing both the number of people that fall and the fall rate. This approach should be considered as a service delivery option.National Institute for Health Research (NIHR) Collaboration for Applied Health Research and Care (CLAHRC) for the South West Peninsul

“It's a lot more complicated than it seems”: physiotherapists' experiences of using compensation strategies in people with Parkinson's

This is the final version. Available from Frontiers Media via the DOI in this record. Data availability statement: The datasets presented in this article are not readily available to protect confidentiality. Requests to access the datasets should be directed to [email protected]: Gait disturbances often result in functional limitations in daily activities and negatively impact the quality of life in people with Parkinson’s disease. Physiotherapists often employ compensation strategies in an attempt to improve patients’ walking. However, little is known about physiotherapists’ experiences in this regard. We evaluated how physiotherapists adopt compensation strategies and what they draw on to inform their clinical decision-making. Methods: We carried out semi-structured online interviews with 13 physiotherapists with current or recent experience working with people with Parkinson’s disease in the United Kingdom. Interviews were digitally recorded and transcribed verbatim. Thematic analysis was utilized. Results: Two main themes were developed from the data. The first theme, optimizing compensation strategies through personalized care, shows how physiotherapists accounted for the individual needs and characteristics of people with Parkinson’s, which resulted in them individually tailoring compensation strategies. The second theme, delivering compensation strategies effectively, considers the available support and perceived challenges with work settings and experience that impact physiotherapists’ ability to deliver compensation strategies. Discussion: Although physiotherapists strived to optimize compensation strategies, there was a lack of formal training in this area, and their knowledge was primarily acquired from peers. Furthermore, a lack of specific knowledge on Parkinson’s can impact physiotherapists’ confidence in maintaining person-centered rehabilitation. However, the question that remains to be answered is what accessible training could address the knowledge–practice gap to contribute to the delivery of better personalized care for people with Parkinson’s.National Institute for Health and Care Research Applied Research Collaboration South West PeninsulaMinistry of Education, Saudi Arabi
