Effects of textured insoles on balance in people with Parkinson’s Disease

Background Degradation of the somatosensory system has been implicated in postural instability and increased falls risk for older people and Parkinson’s disease (PD) patients. Here we demonstrate that textured insoles provide a passive intervention that is an inexpensive and accessible means to enhance the somatosensory input from the plantar surface of the feet. Methods 20 healthy older adults (controls) and 20 participants with PD were recruited for the study. We evaluated effects of manipulating somatosensory information from the plantar surface of the feet using textured insoles. Participants performed standing tests, on two different surfaces (firm and foam), under three footwear conditions: 1) barefoot; 2) smooth insoles; and 3) textured insoles. Standing balance was evaluated using a force plate yielding data on the range of anterior-posterior and medial-lateral sway, as well as standard deviations for anterior-posterior and medial-lateral sway. Results On the firm surface with eyes open both the smooth and textured insoles reduced medial-lateral sway in the PD group to a similar level as the controls. Only the textured insole decreased medial-lateral sway and medial-lateral sway standard deviation in the PD group on both surfaces, with and without visual input. Greatest benefits were observed in the PD group while wearing the textured insoles, and when standing on the foam surface with eyes closed. Conclusions Data suggested that textured insoles may provide a low-cost means of improving postural stability in high falls-risk groups, such as people with PD.

Australian Diabetes Foot Network : practical guideline on the provision of footwear for people with diabetes

Trauma, in the form of pressure and/or friction from footwear, is a common cause of foot ulceration in people with diabetes. These practical recommendations regarding the provision of footwear for people with diabetes were agreed upon following review of existing position statements and clinical guidelines. The aim of this process was not to re-invent existing guidelines but to provide practical guidance for health professionals on how they can best deliver these recommendations within the Australian health system. Where information was lacking or inconsistent, a consensus was reached following discussion by all authors. Appropriately prescribed footwear, used alone or in conjunction with custom-made foot orthoses, can reduce pedal pressures and reduce the risk of foot ulceration. It is important for all health professionals involved in the care of people with diabetes to both assess and make recommendations on the footwear needs of their clients or to refer to health professionals with such skills and knowledge. Individuals with more complex footwear needs (for example those who require custom-made medical grade footwear and orthoses) should be referred to health professionals with experience in the prescription of these modalities and who are able to provide appropriate and timely follow-up. Where financial disadvantage is a barrier to individuals acquiring appropriate footwear, health care professionals should be aware of state and territory based equipment funding schemes that can provide financial assistance. Aboriginal and Torres Strait Islanders and people living in rural and remote areas are likely to have limited access to a broad range of footwear. Provision of appropriate footwear to people with diabetes in these communities needs be addressed as part of a comprehensive national strategy to reduce the burden of diabetes and its complications on the health system.

‘We need to know what’s going on’: views of family members toward the sexual expression of people with dementia in residential aged care

This paper reports on a study which explored the views and attitudes of family members towards the sexual expression of residents with dementia in residential aged care facilities in two states in Australia. Recruitment was challenging and only seven family members agreed to an interview on this topic. Data were analysed using a constant comparative method. Family were generally supportive of residents’ rights to sexual expression, but only some types of behaviours were approved of. There was an acknowledgement that responding to residents’ sexuality was difficult for staff and many families believed that they should be kept informed of their relative’s sexual behaviours and moreover be involved in decision making about it. Findings suggest the need for family education and a larger study to better understand the views and motivations of family carers and how these might impact on the sexual expression of the older person with dementia living in residential aged care.

Foot massage versus quiet presence on agitation and mood in people with dementia : a randomised controlled trial

Background There is increasing interest in using complementary and alternative treatments to manage behavioural and psychological symptoms of dementia such as agitation, aggression and depressed mood. Objective To compare the effect of foot massage (intervention) and quiet presence (control) on agitation and mood in people with dementia. Design A randomised controlled trial using a within-subjects, crossover design. Settings Five long-term care facilities in Brisbane, Australia. The primary outcome was the Cohen-Mansfield Agitation Inventory (CMAI) and the secondary outcome was the Observed Emotion Rating Scale (OERS). The screening and data collection research assistants, families, and care staff were blinded to participant allocation. Participants Participants of the study were 55 long-term care residents aged 74–103 years (mean age 86.5), with moderate to severe dementia and a history of agitated behaviour according to the Pittsburgh Agitation Scale. A computer-program randomised participants to 10-min foot massage (intervention) or quiet presence (control), every weekday for 3 weeks. Results A carry-over effect was identified in the data, and so the data was treated as a parallel groups RCT. The mean total CMAI increased in both groups (reflecting an increase in agitation) with this increase greater in the quiet presence group than the foot massage group (p=0.03). There was a trend towards a difference on OERS General Alertness, with a positive change in alertness for participants in the foot massage group (indicating reduced alertness) and a negative change for participants in the quiet presence group (indicating increased alertness) (F(1,51)=3.88, p=0.05, partial ή2=0.07). Conclusions The findings highlight the need for further research on the specific conditions under which massage might promote relaxation and improve mood for people with dementia. The unfamiliar research assistants and variations in usual activity may have contributed to the increase in agitation and this needs further research.

Literature review : use of respite by carers of people with dementia

Respite care is a cornerstone service for the home management of people with dementia. It is used by carers to mitigate the stress related to the demands of caring by allowing time for them to rest and do things for themselves, thus maintaining the caring relationship at home and perhaps forestalling long-term placement in a residential aged care facility. Despite numerous anecdotal reports in support of respite care, its uptake by carers of people with dementia remains relatively low. The aim of this paper was to examine the factors that constitute the use of respite by carers of people with dementia by reviewing quantitative and qualitative research predominantly from the years 1990 to 2012. Seventysix international studies of different types of respite care were included for this review and their methods were critically appraised. The key topics identified were in relation to information access, the barriers to carers realising need for and seeking respite, satisfaction with respite services including the outcomes for carers and people with dementia, the characteristics of an effective respite service and the role of health workers in providing appropriate respite care. Finally, limitations with considering the literature as a whole were highlighted and recommendations made for future research.

Watermemories : a swimming club for people with dementia

The purpose of this article is to describe the conceptual model and implementation strategies of an evidence-based, aquatic exercise program specifically targeting individuals with dementia—The Watermemories Swimming Club (WSC). Physical exercise not only improves the functional capacity of people with dementia but also has significant effects on other aspects of quality of life such as sleep, appetite, behavioral and psychological symptoms, depression, and falls. Additionally, exercise can improve a person’s overall sense of well-being and positively enhance their sociability. The WSC was designed to increase physical exercise while being easy to implement, safe, and pleasurable. Many challenges were faced along the way, and we discuss how these were overcome. Implications for nurses are also provided.

Exploring the effect of aquatic exercise on behaviour and psychological wellbeing in people with moderate to severe dementia : a pilot study of the Watermemories Swimming Club

Aim To explore the effects of a dementia-specific, aquatic exercise intervention on behavioural and psychological symptoms in people with dementia (BPSD). Method Residents from two aged care facilities in Queensland, Australia, received a 12-week intervention consisting of aquatic exercises for strength, agility, flexibility, balance and relaxation. The Psychological Well-Being in Cognitively Impaired Persons Scale (PW-BCIP) and the Revised Memory and Behaviour Problems Checklist (RMBPC) were completed by registered nurses at baseline, week 6, week 9 and post intervention. Results Ten women and one man (median age = 88.4 years, interquartile range = 12.3) participated. Statistically significant declines in the RMBPC and PW-BCIP were observed over the study period. Conclusion Preliminary evidence suggests that a dementia-specific, aquatic exercise intervention reduces BPSD and improves psychological well-being in people with moderate to severe dementia. With further testing, this innovative intervention may prove effective in addressing some of the most challenging aspects of dementia care.

What is the evidence to guide best practice for the management of older people with cognitive impairment presenting to emergency departments? A systematic review

The aim of this study was to conduct a systematic literature review of research-based studies to identify practices designed to meet the specific care needs of older cognitively impaired patients in emergency departments (ED). A systematic literature review of studies was completed using PRIMSA methodology. The search criteria included articles from both emergency and acute care settings. A total of 944 articles were screened, and a total of 43 articles were identified as eligible. The review found a number of intervention studies to improve quality of care for older persons with cognitive impairment carried out or commenced in emergency settings, including interventions to improve cognitive impairment recognition (n = 9) and clinical approaches to reduce falls (n = 1) and both delirium incidence and prevalence (n = 2). Relevant studies carried out in acute care settings regarding cognitive impairment recognition (n = 4) and primary and secondary prevention of delirium (n = 18) and intervention studies that reduced the prescription of deliriogenic drugs (n = 1), reduced behavioral symptoms and discomfort (n = 7), and improved nutritional intake (n = 1) in hospitalized older persons with dementia were also identified. There is limited research available that reports interventions that improve the quality of care of older ED patients with cognitive impairment. Although this review found evidence obtained from the acute care setting, additional research is needed to identify whether these interventions are beneficial in fast-paced emergency settings.

Dietetic practice by Australian and Canadian dietitians with people with Parkinson's disease

Although Parkinson’s disease (PD) is a complex disease for which appropriate nutrition management is important, limited evidence is currently available to support dietetic practice. Existing PD-specific guidelines do not span all phases of the Nutrition Care Process (NCP). This study aimed to document PD-specific nutrition management practice by Australian and Canadian dietitians. DAA members and PEN subscribers were invited to participate in an online survey (late 2011). Eighty-four dietitians responded (79.8% Australian). The majority (70.2%) worked in the clinical setting. Existing non-PD guidelines were used by 52.4% while 53.6% relied on self-initiated literature reviews. Weight loss/malnutrition, protein intake, dysphagia and constipation were common issues in all NCP phases. Respondents also requested more information/evidence for these topics. Malnutrition screening (82.1%) and assessment (85.7%) were routinely performed. One-third did not receive referrals for weight loss for overweight/obesity. Protein intake meeting gender/age recommendations (69.0%), and high energy/high protein diets to manage malnutrition (82.1%) were most commonly used. Constipation management was through high fibre diets (86.9%). Recommendations for spacing of meals and PD medications varied with 34.5% not making recommendations. Nutritional diagnosis (70.2%) and stage of disease (61.9%) guided monitoring frequency. Common outcome measures included appropriate weight change (97.6%) and regular bowel movements (88.1%). With limited PD-specific guidance, dietitians applied best available evidence for other groups with similar issues. Dietitians requested evidence-based guidelines specifically for the nutritional management of PD. Guideline development should focus on those areas reported as commonly encountered. This process can identify the gaps in evidence to guide future research.

Use of a photographic food diary method to document dietary intake in people with Parkinson's Disease

Cognitive impairment and physical disability are common in Parkinson’s disease (PD). As a result diet can be difficult to measure. This study aimed to evaluate the use of a photographic dietary record (PhDR) in people with PD. During a 12-week nutrition intervention study, 19 individuals with PD kept 3-day PhDRs on three occasions using point-and-shoot digital cameras. Details on food items present in the PhDRs and those not photographed were collected retrospectively during an interview. Following the first use of the PhDR method, the photographer completed a questionnaire (n=18). In addition, the quality of the PhDRs was evaluated at each time point. The person with PD was the sole photographer in 56% of the cases, with the remainder by the carer or combination of person with PD and the carer. The camera was rated as easy to use by 89%, keeping a PhDR was considered acceptable by 94% and none would rather use a “pen and paper” method. Eighty-three percent felt confident to use the camera again to record intake. Of the photos captured (n=730), 89% were of adequate quality (items visible, in-focus), while only 21% could be used alone (without interview information) to assess intake. Over the study, 22% of eating/drinking occasions were not photographed. PhDRs were considered an easy and acceptable method to measure intake among individuals with PD and their carers. The majority of PhDRs were of adequate quality, however in order to quantify intake the interview was necessary to obtain sufficient detail and capture missing items.

A randomized controlled trial of self-management programme improves health-related outcomes of older people with heart failure

Aims This paper is a report on the effectiveness of a self-management programme based on the self-efficacy construct, in older people with heart failure. Background Heart failure is a major health problem worldwide, with high mortality and morbidity, making it a leading cause of hospitalization. Heart failure is associated with a complex set of symptoms that arise from problems in fluid and sodium retention. Hence, managing salt and fluid intake is important and can be enhanced by improving patients' self-efficacy in changing their behaviour. Design Randomized controlled trial. Methods Heart failure patients attending cardiac clinics in northern Taiwan from October 2006–May 2007 were randomly assigned to two groups: control (n = 46) and intervention (n = 47). The intervention group received a 12-week self-management programme that emphasized self-monitoring of salt/fluid intake and heart failure-related symptoms. Data were collected at baseline as well as 4 and 12 weeks later. Data analysis to test the hypotheses used repeated-measures anova models. Results Participants who received the intervention programme had significantly better self-efficacy for salt and fluid control, self-management behaviour and their heart failure-related symptoms were significantly lower than participants in the control group. However, the two groups did not differ significantly in health service use. Conclusion The self-management programme improved self-efficacy for salt and fluid control, self-management behaviours, and decreased heart failure-related symptoms in older Taiwanese outpatients with heart failure. Nursing interventions to improve health-related outcomes for patients with heart failure should emphasize self-efficacy in the self-management of their disease.

Research participation by people with intellectual disability and mental health issues : an examination of the processes of consent

Balancing the demands of research and ethics is always challenging and even more so when recruiting vulnerable groups. Within the context of current legislation and international human rights declarations, it is strongly advocated that research can and must be undertaken with all recipients of health care services. Research in the field of intellectual disability presents particular challenges in regard to consenting processes. This paper is a critical reflection and analysis of the complex processes undertaken and events that occurred in gaining informed consent from people with intellectual disability to participate in a study exploring their experiences of being an inpatient in mental health hospitals within Aotearoa/New Zealand. A framework based on capacity, information and voluntariness is presented with excerpts from the field provided to explore consenting processes. The practical implications of the processes utilised are then discussed in order to stimulate debate regarding clearer and enhanced methods of gaining informed consent from people with intellectual disability.

Validity of accelerometry for measurement of activity in people with brain injury

Purpose To evaluate the validity of a uniaxial accelerometer (MTI Actigraph) for measuring physical activity in people with acquired brain injury (ABI) using portable indirect calorimetry (Cosmed K4b(2)) as a criterion measure. Methods Fourteen people with ABI and related gait pattern impairment (age 32 +/- 8 yr) wore an MTI Actigraph that measured activity (counts(.)min-(1)) and a Cosmed K4b(2) that measured oxygen consumption (mL(.)kg(-1.)min(-1)) during four activities: quiet sitting (QS) and comfortable paced (CP), brisk paced (BP), and fast paced (FP) walking. MET levels were predicted from Actigraph counts using a published equation and compared with Cosmed measures. Predicted METs for each of the 56 activity bouts (14 participants X 4 bouts) were classified (light, moderate, vigorous, or very vigorous intensity) and compared with Cosmed-based classifications. Results Repeated-measures ANOVA indicated that walking condition intensities were significantly different (P < 0.05) and the Actigraph detected the differences. Overall correlation between measured and predicted METs was positive, moderate, and significant (r = 0.74). Mean predicted METs were not significantly different from measured for CP and BP, but for FP walking, predicted METs were significantly less than measured (P < 0.05). The Actigraph correctly classified intensity for 76.8% of all activity bouts and 91.5% of light- and moderate-intensity bouts. Conclusions Actigraph counts provide a valid index of activity across the intensities investigated in this study. For light to moderate activity, Actigraph-based estimates of METs are acceptable for group-level analysis and are a valid means of classifying activity intensity. The Actigraph significantly underestimated higher intensity activity, although, in practice, this limitation will have minimal impact on activity measurement of most community-dwelling people with ABI.

A smoking cessation intervention for people with chronic Hepatitis C : a randomised controlled trial

Purpose The purpose of this study was to examine the validity of current practice in smoking cessation for the general population i.e., a telephone counselling and nicotine replacement therapy (NRT) intervention and its applicability to people with chronic hepatitis-C. Methods A randomised controlled trial was conducted over twelve weeks. Following consent, ninety-two smokers (outpatients) with chronic hepatitis-C were recruited by the Nurse Practitioner hepatology, randomly assigned and stratified by number of cigarettes smoked (i.e., 15 and greater; <15) into the intervention group (telephone counselling and NRT) and control group (telephone counselling). Outcomes measured included socio-demographics, nicotine dependence, depression, anxiety and stress and quality of life (QOL). All statistical data were analysed using SPSS. Results After 12 weeks, the intervention group showed a sustained reduction of smoking i.e., 5.8(CI: 2.4,9.3) cigarettes less per day, whereas the control group showed 1.6(CI:-1.9,5.2) cigarette reduction. Although not statistically significantly different (F=2.9, p=0.090) the intervention group on average smoked 4.2 fewer cigarettes compared to the control group. After twelve weeks, seven patients in the intervention group and three patients in the control group reported quitting. Whilst not statistically significant (Fisher’s Exact, p=0.311) this was a clinically significant result. No differences were found for nicotine dependence or depression, anxiety and stress. The intervention group experienced no change in QOL (-0.1,CI:-0.9, 0.6), however, the environmental score for the control group decreased by 1.8(CI:1.0, 2.6,p= 0.001). This was statistically significant. Conclusion A telephone counselling and nicotine replacement therapy intervention from the nurse practitioner, hepatology reduced smoking in patients with chronic hepatitis-C. The intervention group showed a sustained reduction over the 12 weeks. A total of 10 patients quit smoking at the end of the study. QOL deteriorated in the environmental subscale for the control group. These results informed a nurse practitioner model of care for approaches to smoking cessation.
