Activity and footwear characteristics in people with and without plantar heel pain: A matched cross-sectional observational study

BACKGROUND

Activity and footwear may be associated with plantar heel pain (PHP), however both factors have rarely been investigated. The aim of this study was to investigate activity and footwear characteristics in PHP while controlling for important confounders.

METHOD

This cross-sectional observational study compared 50 participants with PHP to 25 participants without PHP who were matched for age, sex and body mass index. Activity was measured using the Stanford Activity Questionnaire, as well as the number of hours per day participants stood for, and whether they stood on hard floors. Footwear characteristics were measured using the footwear domain of the Foot Health Status Questionnaire (FHSQ), as well as the style of shoe, heel height, and the Shore A hardness value of the heel of the shoe most used.

RESULTS

Participants with PHP stood for more than twice as long as participants without PHP (mean difference 3.4 hours, p < 0.001, large effect size). Participants with PHP also reported greater difficulty accessing suitable footwear (FHSQ footwear domain mean difference (MD) 22 points, p = 0.002, large effect size (ES), and they wore harder-heeled shoes (Shore A MD 6.9 units, p = 0.019, medium ES). There were no significant differences for physical activity, whether they stood on hard floors, the style of shoe they wore, or heel height.

CONCLUSIONS

Compared to people without PHP, people with PHP stand for more than twice the amount of time each day, have substantial difficulties accessing suitable footwear, and the primary shoes they wear are harder under the heel.

Futsal playing surface characteristics significantly affect perceived traction and change of direction performance among experienced futsal players

We aimed to clarify the effect of different futsal playing surface structural properties on the resultant change of direction (COD) performance, perceived traction and frictional properties. Twenty experienced male university soccer players performed a COD slalom-course test and perceived traction evaluation on three different types of playing surfaces (area-elastic: AE, point-elastic no.1: PE1 and point-elastic no.2: PE2). Frictional properties of these surfaces were mechanically evaluated against a futsal shoe, using a hydraulic moving force platform, and expressed as available friction coefficient (AFC). In the COD performance test, the participants performed significantly better on the point-elastic surfaces (PE1 and PE2) when compared to the area-elastic surface (AE) (p < 0.05). Also, the PE2 surface was found to have the highest perceived traction (p < 0.001). The findings suggest that the relatively higher (4%) AFC explains the improvement in performance and traction perception on the PE2 surface. In this study, we successfully demonstrated that the structural difference (AE or PE) of futsal playing surface has a significant impact on the COD performance of experienced futsal players and their perceived level of traction (PE2) and the frictional properties.

Protocol for the SAFEST review: the Shock-Absorbing Flooring Effectiveness SysTematic review including older adults and staff in hospitals and care homes

INTRODUCTION

Falls in hospitals and care homes are a major issue of international concern. Inpatient falls are the most commonly reported safety incident in the UK's National Health Service (NHS), costing the NHS £630 million a year. Injurious falls are particularly life-limiting and costly. There is a growing body of evidence on shock-absorbing flooring for fall-related injury prevention; however, no systematic review exists to inform practice.

METHODS AND ANALYSIS

We will systematically identify, appraise and summarise studies investigating the clinical and cost-effectiveness, and experiences of shock-absorbing flooring in hospitals and care homes. Our search will build on an extensive search conducted by a scoping review (inception to May 2016). We will search electronic databases (AgeLine, CINAHL, MEDLINE, NHS Economic Evaluation Database, Scopus and Web of Science; May 2016-present), trial registries and grey literature. We will conduct backward and forward citation searches of included studies, and liaise with study researchers. We will evaluate the influence of floors on fall-related injuries, falls and staff work-related injuries through randomised and non-randomised studies, consider economic and qualitative evidence, and implementation factors. We will consider risk of bias, assess heterogeneity and explore potential effect modifiers via subgroup analyses and sensitivity analyses. Where appropriate we will combine studies through meta-analysis. We will use the GRADE (Grading of Recommendations, Assessment, Development and Evaluations) approach to evaluate the quality of evidence and present the results using summary of findings tables, and adhere to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guidelines.

ETHICS AND DISSEMINATION

We will follow the ethical principles of systematic review conduct, by attending to publication ethics, transparency and rigour. Our dissemination plan includes peer-reviewed publication, presentations, press release, stakeholder symposium, patient video and targeted knowledge-to-action reports. This review will inform decision-making around falls management in care settings and identify important directions for future research.

Pilot cluster randomised controlled trial of flooring to reduce injuries from falls in wards for older people

BACKGROUND

falls disproportionately affect older people, who are at increased risk of falls and injury. This pilot study investigates shock-absorbing flooring for fall-related injuries in wards for frail older people.

METHODS

we conducted a non-blinded cluster randomised trial in eight hospitals in England between April 2010 and August 2011. Each site allocated one bay as the 'study area', which was randomised via computer to intervention (8.3-mm thick Tarkett Omnisports EXCEL) or control (2-mm standard in situ flooring). Sites had an intervention period of 1 year. Anybody admitted to the study area was eligible. The primary outcome was the fall-related injury rate. Secondary outcomes were injury severity, fall rate and adverse events.

RESULTS

during the intervention period, 226 participants were recruited to each group (219 and 223 were analysed in the intervention and control group, respectively). Of 35 falls (31 fallers) in the intervention group, 22.9% were injurious, compared with 42.4% of 33 falls (22 fallers) in the control group [injury incident rate ratio (IRR) = 0.58, 95% CI = 0.18-1.91]. There were no moderate or major injuries in the intervention group and six in the control group. The fall IRR was 1.07 (95% CI = 0.64-1.81). Staff at intervention sites raised concerns about pushing equipment, documenting one pulled back.

CONCLUSIONS

future research should assess shock-absorbing flooring with better 'push/pull' properties and explore increased faller risk. We estimate a future trial will need 33,480-52,840 person bed-days per arm.
