BackgroundExercise programmes are a relatively inexpensive, low-risk option compared with other, more invasive therapies for treatment of leg pain on walking (intermittent claudication (IC)). This is the fourth update of a review first published in 1998. ObjectivesOur goal was to determine whether an exercise programme was effective in alleviating symptoms and increasing walking treadmill distances and walking times in people with intermittent claudication. Secondary objectives were to determine whether exercise was effective in preventing deterioration of underlying disease, reducing cardiovascular events, and improving quality of life. Search methodsFor this update, the Cochrane Vascular Information Specialist searched the Specialised Register (last searched 15 November 2016) and the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 10) via the Cochrane Register of Studies Online, along with trials registries. Selection criteriaRandomised controlled trials of an exercise regimen versus control or versus medical therapy for people with IC due to peripheral arterial disease (PAD). We included any exercise programme or regimen used for treatment of IC, such as walking, skipping, and running. Inclusion of trials was not affected by duration, frequency, or intensity of the exercise programme. Outcome measures collected included treadmill walking distance (time to onset of pain or pain-free walking distance and maximum walking time or maximum walking distance), ankle brachial index (ABI), quality of life, morbidity, or amputation; if none of these was reported, we did not include the trial in this review. Data collection and analysisFor this update (2017), RAL and AH selected trials and extracted data independently. We assessed study quality by using the Cochrane 'Risk of bias' tool. We analysed continuous data by determining mean differences (MDs) and 95% confidence intervals (CIs), and dichotomous data by determining risk ratios (RRs) and 95% CIs. We pooled data using a fixed-effect model unless we identified significant heterogeneity, in which case we used a random-effects model. We used the GRADE approach to assess the overall quality of evidence supporting the outcomes assessed in this review.

Simple clinical measures of gait velocity and ankle muscle strength may be used to identify people with DM at risk of falling, allowing preventative strategies to be implemented.

BackgroundThere is some evidence to suggest that dog ownership may improve physical activity (PA) among older adults, but to date, studies examining this, have either depended on self-report or incomplete datasets due to the type of activity monitor used to record physical activity. Additionally, the effect of dog ownership on sedentary behaviour (SB) has not been explored. The aim of the current study was to address these issues by using activPAL monitors to evaluate the influence of dog ownership on health enhancing PA and SB in a longitudinal study of independently-mobile, community-dwelling older adults.MethodsStudy participants (43 pairs of dog owners and non-dog owners, matched on a range of demographic variables) wore an activPAL monitor continuously for three, one-week data collection periods over the course of a year. Participants also reported information about their own and their dog demographics, caring responsibilities, and completed a diary of wake times. Diary data was used to isolate waking times, and outcome measures of time spent walking, time spent walking at a moderate cadence (>100 steps/min), time spent standing, time spent sitting, number of sitting events (continuous periods of sitting), and the number of and of time spent sitting in prolonged events (>30 min). For each measure, a linear mixed effects model with dog ownership as a fixed effect, and a random effects structure of measurement point nested in participant nested in pair was used to assess the effect of dog ownership.ResultsOwning a dog indicated a large, potentially health improving, average effect of 22 min additional time spent walking, 95%CI (12, 34), and 2760 additional steps per day, 95%CI (1667, 3991), with this additional walking undertaken at a moderate intensity cadence. Dog owners had significantly fewer sitting events. However, there were no significant differences between the groups for either the total time spent sitting, or the number or duration of prolonged sedentary events.ConclusionsThe scale of the influence of dog ownership on PA found in this study, indicates that future research regarding PA in older adults should assess and report dog ownership and/or dog walking status.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-017-4422-5) contains supplementary material, which is available to authorized users.

with diabetes and no neuropathy (70 ± 2.9years). The temporal and spatial parameters of gait were evaluated using the GAITRite walkway. Subjects undertook four walks under normal walking conditions (single task); four times while simultaneously undertaking an additional motor task, carrying a tray with cups of water (dual task); and four times whilst undertaking a cognitive dual task, counting backwards in sevens. This arithmetic task was also completed in sitting.Results: For all gait variables there was a statistically significant difference between the groups. Subjects with DPN walked slower and with smaller steps compared to those with diabetes. In general the secondary task had a significant and adverse effect on the gait parameters and this effect was greater for those with DPN in both absolute and relative terms. Both groups had poorer arithmetic ability when walking compared to sitting. Discussion:Patients with DPN have different gait parameters to diabetic patients without neuropathy. Problems with divided attention when walking were more evident in the DPN group and may increase their risk of falls.

Both techniques provided adequate pain relief, enabled early mobilisation and accelerated rehabilitation and good patient-reported outcomes up to one year post-operatively. PCEA and LIA are associated with similar clinical outcomes following TKA. Cite this article: Bone Joint J 2016;98-B1189-96.

BackgroundImplementation of the Norwegian government’s Coordination Reform (2012) aims to decentralise health care services from centralised hospitals to local communities. Radiological services in Norway are mainly organised in hospitals, because of the significant financial and human resource demands engendered by the need for advanced technological equipment, and specialised staff. Some selected conventional x-ray services have been decentralised into rural communities. The purpose of this single case study was to highlight experiences from different stakeholders’ of organising decentralised radiological services in a rural area in Norway.MethodsA qualitative single case study design was adopted, collected data using focus groups with healthcare professionals and managers to obtain stakeholder’s experiences of the radiological services in this rural area. The key emergent themes from the literature, decentralisation, quality, professional roles, organisation and economic consequences were discussed with each focus group. Thematic analysis was used for analyzing the primary data collected.ResultsFour main themes emerged from the focus groups: 1) organisation, 2) quality and safety, 3) funding of radiological services and 4) cooperation between health care professions and health care levels. It was found that the organisation of decentralised radiological services to rural areas is challenging because of the way health services are structured in Norway. The quality of service was found to be inadequate in some areas because of the superficial level of training given to non-radiographic staff. The experience is that the Norwegian funding system hinders an efficient decentralised health care service. Effective cooperation and responsibility between health care professions and levels was challenging. There needs to be improved co-working by clearly defining roles and responsibilities.ConclusionsA key recommendation for the organisation of rural radiological service was the development of a satellite link with an acute hospital. Quality of the service could be improved and should be given priority. Structural change to the financial system whereby money follows patients, might also facilitate more patientcentred services across healthcare levels. Improved mutual understanding between rural radiological services and hospital specialists and managers is important for a high quality and consistent radiological service to be delivered across Norway.
