Addressing internet training issues for people with Parkinson's disease

The Internet enables access to information, services, support and participation in leisure opportunities. Some populations, including people with disabilities, lack access to these opportunities through the Internet. Barriers may include finances, physical access, lack of resources and inaccessible websites. Limited access to Internet training is an additional barrier for people with communication impairments. People with Parkinson's disease (PD) may have difficulty accessing usual Internet training due to high-level language, cognitive and physical limitations. Aphasia-friendly Internet training materials were trialed with this population to investigate if participants could learn to use the Internet and would benefit from Internet training. The tutors' experience was also investigated using qualitative measures. Seven people with PD were matched with volunteer tutors. These pairs met for six Internet training lessons using training materials available as a free download from: http://dexter.shrs.uq.edu.au/cdaru/aphasiagroups/. Pre and post-test Internet skills assessments and attitudinal questionnaires were conducted. Significant differences between pre and post-test scores were found. Participants reached varying levels of independence on Internet tasks. Favorable outcomes were reported by participants, and tutors reported a positive experience. Further investigation is recommended to determine the efficacy of this approach compared with other training avenues and with other communication-impaired populations. Practical and theoretical implications for speech pathology practice are discussed.

Integrating technology in the workplace for people with spinal cord injury

Computer technology can overcome mobility and functional limitations resulting from spinal cord injury (SCI) and enable re-employment. This study aimed to identify barriers and supports to effective technology use at work from the unique perspectives of technology users themselves. A qualitative research design was used to explore the perspectives of 11 technology users with SCI. In-depth, open-ended interviews and observations were conducted at each person’s workplace. Five major themes emerged: identifying the best or right technology; acquiring the technology; customizing and learning to use the technology; supporting the technology; and empowerment. Understanding these consumer perspectives enables professionals to empower people with SCI to optimize their work potential.

Access to written information for people with aphasia

Background: Accessibility is often constructed in terms of physical accessibility. There has been little research into how the environment can accommodate the communicative limitations of people with aphasia. Communication accessibility for people with aphasia is conceptualised in this paper within the World Health Organisation's International Classification of Functioning, Disability and Health (ICF). The focus of accessibility is considered in terms of the relationship between the environment and the person with the disability. Thus: This paper synthesises the results of three Studies that examine the effectiveness of aphasia-friendly written material. Main Contribution: The first study (Rose, Worrall, & McKenna, 2003) found that aphasia-friendly formatting of written health information improves comprehension by people with aphasia, but not everyone prefers aphasia-friendly formatting. Brennan, Worrall, and McKenna (in press) found that the aphasia-friendly strategy of augmenting text with pictures, particularly ClipArt and Internet images, may be distracting rather than helpful. Finally, Egan, Worrall, and Oxenham (2004) found that the use of ail aphasia-friendly written training manual was instrumental in assisting people with aphasia to learn the Internet. Conclusion: Aphasia-friendly formatting appears to improve the accessibility of written material for people with aphasia. Caution is needed when considering the use of illustrations, particularly ClipArt and Internet images, when creating aphasia-friendly materials. A research, practice, and policy agenda for introducing aphasia-friendly formatting is proposed.

Physical activity for people with cardiovascular disease: recommendations of the National Heart Foundation of Australia

* To provide physical activity recommendations for people with cardiovascular disease, an Expert Working Group of the National Heart Foundation of Australia in late 2004 reviewed the evidence since the US Surgeon General’s Report: physical activity and health in 1996. * The Expert Working Group recommends that: o people with established clinically stable cardiovascular disease should aim, over time, to achieve 30 minutes or more of moderate intensity physical activity on most, if not all, days of the week; o less intense and even shorter bouts of activity with more rest periods may suffice for those with advanced cardiovascular disease; and o regular low-to-moderate level resistance activity, initially under the supervision of an exercise professional, is encouraged. * Benefits from regular moderate physical activity for people with cardiovascular disease include augmented physiological functioning, lessening of cardiovascular symptoms, enhanced quality of life, improved coronary risk profile, superior muscle fitness and, for survivors of acute myocardial infarction, lower mortality. * The greatest potential for benefit is in those people who were least active before beginning regular physical activity, and this benefit may be achieved even at relatively low levels of physical activity. * Medical practitioners should routinely provide brief, appropriate advice on physical activity to people with well-compensated, clinically stable cardiovascular disease.

Meeting in the middle: Improving communication in primary health care consultations with people with an intellectual disability

The increased presence and participation in Australian society of people with an intellectual disability provides challenges for the provision of primary health care. General practitioners (GPs) identify themselves as ill equipped to provide for this heterogeneous population. A major obstacle to the provision of appropriate health care is seen as inadequate communication between the GP and the person with an intellectual disability, who may or may not be accompanied by a carer or advocate. This qualitative study in which five GPs, three people with intellectual disability, seven carers and two advocates (parent and friend) were interviewed was conducted in Brisbane, Australia. The aim was to better understand the factors that have an impact upon the success of communication in a medical consultation. Findings suggested that GPs were concerned with the aspects of communication difficulties which influenced their ability to adequately diagnose, manage and inform patients. Implications for practice management were also identified. People with intellectual disability reported frustration when they felt that they could not communicate adequately with the GP and annoyance when they were not included in the communication exchange. Carers were strong advocates for the person with intellectual disability, but indicated insufficient skill and knowledge to provide the level of assistance required in the consultation. The outcome was a model of cooperation that outlined the responsibilities of all players in the medical encounter, prior to, during and after the event.

Hip strategy for balance control in quiet standing is reduced in people with low back pain

Study Design. Quiet stance on supporting bases with different lengths and with different visual inputs were tested in 24 study participants with chronic low back pain (LBP) and 24 matched control subjects. Objectives. To evaluate postural adjustment strategies and visual dependence associated with LBP. Summary of Background Data. Various studies have identified balance impairments in patients with chronic LBP, with many possible causes suggested. Recent evidence indicates that study participants with LBP have impaired trunk muscle control, which may compromise the control of trunk and hip movement during postural adjustments ( e. g., hip strategy). As balance on a short base emphasizes the utilization of the hip strategy for balance control, we hypothesized that patients with LBP might have difficulties standing on short bases. Methods. Subjects stood on either flat surface or short base with different visual inputs. A task was counted as successful if balance was maintained for 70 seconds during bilateral stance and 30 seconds during unilateral stance. The number of successful tasks, horizontal shear force, and center-of-pressure motion were evaluated. Results. The hip strategy was reduced with increased visual dependence in study participants with LBP. The failure rate was more than 4 times that of the controls in the bilateral standing task on short base with eyes closed. Analysis of center-of-pressure motion also showed that they have inability to initiate and control a hip strategy. Conclusions. The inability to control a hip strategy indicates a deficit of postural control and is hypothesized to result from altered muscle control and proprioceptive impairment.

Cutaneous stimulation from patella tape causes a differential increase in vasti muscle activity in people with patellofemoral pain

Patella taping reduces pain ill individuals with patellofemoral pain (PFP), although the mechanism remains unclear. One possibility is that patella taping modifies vasti muscle activity via stimulation of cutaneous afferents. The aim of this study was to investigate the effect of stretching the skin over the patella on vasti Muscle activity in people with PFP. Electromyographic activity (EMG) of individual motor units in vastus medialis obliquus (VMO) was recorded via a needle electrode and from Surface electrodes placed over VMO and vastus lateralis (VL). A tape was applied to the skin directly over the patella and stretch was applied via the tape in three directions, while subjects maintained a gentle isometric knee extension effort at constant force. Recordings were made from five separate motor units in each direction. Stretch applied to the skin over the patella increased VMO surface EMG and was greatest with lateral stretch. There was no change in VL surface EMG activity. While there was no net increase in motor unit firing rate, it was increased in the majority of motor units during lateral stretch. Application of stretch to the skin over VMO via the tape can increase VMO activity, suggesting that cutaneous stimulation may be one mechanism by which patella taping produces a clinical effect.

The employment of people with mental illness

People with a mental illness are among the most socially and economically marginalised members of the community. They experience high levels of unemployment and nonparticipation in the labour force. Unemployment has a number of negative effects including the loss of purpose, structure, roles and status and a sense of identity which employment brings. Employment enables social inclusion in the wider community and is an important way that people with a mental illness can meaningfully participate in the wider community. Australia has a mental health strategy, which guides the ongoing reform of mental health services. However, specific strategies to address the social and economic marginalisation of people with a mental illness have not been addressed. A recovery-oriented approach is recommended, which integrates the key sectors involved. To date there has been little intersectoral collaboration between the various sectors such as mental health services, housing, and vocational services. People require more role-specific assistance to enable them to participate in socially valued roles implicit with citizenship. There is a need to formulate improved pathways to assistance and more evidence-based forms of assistance to re-establish career pathways. This report aims to: 1) collect relevant overseas and Australian evidence about the employment of people with mental illness; 2) identify the potential benefits of employment; 3) describe patterns of labour force participation in Australia among people with mental illness; 4) identify how mental illness can cause barriers to employment; 5) outline the type of employment restrictions reported by people with mental illness; 6) identify the evidence-based ingredients of employment assistance; 7) identify relevant policy implications; and 8) suggest strategies to improve employment outcomes and career prospects for people with mental illness.

The relative benefits of endurance and strength training on the metabolic factors and muscle function of people with type 2 diabetes mellitus

Objective: To compare the effects of a 4-month strength training (ST) versus aerobic endurance training (ET) program on metabolic control, muscle strength, and cardiovascular endurance in subjects with type 2 diabetes mellitus (T2D). Design: Randomized controlled trial. Setting: Large public tertiary hospital. Participants: Twenty-two T21) participants (I I men, I I women; mean age +/- standard error, 56.2 +/- 1.1 y; diabetes duration, 8.8 +/- 3.5y) were randomized into a 4-month ST program and 17 T2D participants (9 men, 8 women; mean age, 57.9 +/- 1.4y; diabetes duration, 9.2 +/- 1.7y) into a 4-month ET program. Interventions: ST (up to 6 sets per muscle group per week) and ET (with an intensity of maximal oxygen consumption of 60% and a volume beginning at 15min and advancing to a maximum of 30min 3X/wk) for 4 months. Main Outcome Measures: Laboratory tests included determinations of blood glucose, glycosylated hemoglobin (Hb A(1c)), insulin, and lipid assays. Results: A significant decline in Hb A, was only observed in the ST group (8.3% +/- 1.7% to 7.1% +/- 0.2%, P=.001). Blood glucose (204 +/- 16mg/dL to 147 +/- 8mg/dL, P <.001) and insulin resistance (9.11 +/- 1.51 to 7.15 +/- 1.15, P=.04) improved significantly in the ST group, whereas no significant changes were observed in the ET group. Baseline levels of total cholesterol (207 +/- 8mg/dL to 184 +/- 7mg/dL, P <.001), low-density lipoprotein cholesterol (120 +/- 8mg/dL to 106 +/- 8mg/dL, P=.001), and triglyceride levels (229 +/- 25mg/dL to 150 +/- 15mg/dL, P=.001) were significantly reduced and high-density lipoprotein cholesterol (43 +/- 3mg/dL to 48 +/- 2mg/dL, P=.004) was significantly increased in the ST group; in contrast, no such changes were seen in the ET group. Conclusions: ST was more effective than ET in improving glycemic control. With the added advantage of an improved lipid profile, we conclude that ST may play an important role in the treatment of T2D.

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.
