ItemRobotics to enable older adults to remain living at home.(Hindawi Limited, 2012)Given the rapidly ageing population, interest is growing in robots to enable older people to remain living at home. We conducted a systematic review and critical evaluation of the scientific literature, from 1990 to the present, on the use of robots in aged care. The key research questions were as follows: (1) what is the range of robotic devices available to enable older people to remain mobile, independent, and safe? and, (2) what is the evidence demonstrating that robotic devices are effective in enabling independent living in community dwelling older people? Following database searches for relevant literature an initial yield of 161 articles was obtained. Titles and abstracts of articles were then reviewed by 2 independent people to determine suitability for inclusion. Forty-two articles met the criteria for question 1. Of these, 4 articles met the criteria for question 2. Results showed that robotics is currently available to assist older healthy people and people with disabilities to remain independent and to monitor their safety and social connectedness. Most studies were conducted in laboratories and hospital clinics. Currently limited evidence demonstrates that robots can be used to enable people to remain living at home, although this is an emerging smart technology that is rapidly evolving.

ItemFeldenkrais Method Balance Classes Improve Balance in Older Adults: A Controlled Trial(HINDAWI LTD, 2011)The objective of this study was to investigate the effects of Feldenkrais Method balance classes on balance and mobility in older adults. This was a prospective non-randomized controlled study with pre/post measures. The setting for this study was the general community. A convenience sample of 26 community-dwelling older adults (median age 75 years) attending Feldenkrais Method balance classes formed the Intervention group. Thirty-seven volunteers were recruited for the Control group (median age 76.5 years). A series of Feldenkrais Method balance classes (the 33312Getting Grounded Gracefully33313 series), two classes per week for 10 weeks, were conducted. Main outcome measures were Activities-Specific Balance Confidence (ABC) questionnaire, Four Square Step Test (FSST), self-selected gait speed (using GAITRite instrumented gait mat). At re-testing, the Intervention group showed significant improvement on all of the measures (ABC, P = .016, FSST, P = .001, gait speed, P < .001). The Control group improved significantly on one measure (FSST, P < .001). Compared to the Control group, the Intervention group made a significant improvement in their ABC score (P = .005), gait speed (P = .017) and FSST time (P = .022). These findings suggest that Feldenkrais Method balance classes may improve mobility and balance in older adults.

ItemThe FLASSH study: protocol for a randomised controlled trial evaluating falls prevention after stroke and two sub-studies(BIOMED CENTRAL LTD, 2009-03-31)BACKGROUND: Falls are common in stroke survivors returning home after rehabilitation, however there is currently a lack of evidence about preventing falls in this population. This paper describes the study protocol for the FLASSH (FaLls prevention After Stroke Survivors return Home) project. METHODS AND DESIGN: This randomised controlled trial aims to evaluate the effectiveness of a multi-factorial falls prevention program for stroke survivors who are at high risk of falling when they return home after rehabilitation. Intervention will consist of a home exercise program as well as individualised falls prevention and injury minimisation strategies based on identified risk factors for falls. Additionally, two sub-studies will be implemented in order to explore other key areas related to falls in this population. The first of these is a longitudinal study evaluating the relationship between fear of falling, falls and function over twelve months, and the second evaluates residual impairment in gait stability and obstacle crossing twelve months after discharge from rehabilitation. DISCUSSION: The results of the FLASSH project will inform falls prevention practice for stroke survivors. If the falls prevention program is shown to be effective, low cost strategies to prevent falls can be implemented for those at risk around the time of discharge from rehabilitation, thus improving safety and quality of life for stroke survivors. The two sub-studies will contribute to the overall understanding and management of falls risk in stroke survivors. TRIAL REGISTRATION: This trial is registered with the Australian and New Zealand Clinical Trials Registry (ACTRN012607000398404).

ItemEffectiveness of balance training exercise in people with mild to moderate severity Alzheimer's disease: protocol for a randomised trial.(Springer Science and Business Media LLC, 2009-07-16)BACKGROUND: Balance dysfunction and falls are common problems in later stages of dementia. Exercise is a well-established intervention to reduce falls in cognitively intact older people, although there is limited randomised trial evidence of outcomes in people with dementia. The primary objective of this study is to evaluate whether a home-based balance exercise programme improves balance performance in people with mild to moderate severity Alzheimer's disease. METHODS/DESIGN: Two hundred and fourteen community dwelling participants with mild to moderate severity Alzheimer's disease will be recruited for the randomised controlled trial. A series of laboratory and clinical measures will be used to evaluate balance and mobility performance at baseline. Participants will then be randomized to receive either a balance training home exercise programme (intervention group) from a physiotherapist, or an education, information and support programme from an occupational therapist (control group). Both groups will have six home visits in the six months following baseline assessment, as well as phone support. All participants will be re-assessed at the completion of the programme (after six months), and again in a further six months to evaluate sustainability of outcomes. The primary outcome measures will be the Limits of Stability (a force platform measure of balance) and the Step Test (a clinical measure of balance). Secondary outcomes include other balance and mobility measures, number of falls and falls risk measures, cognitive and behavioural measures, and carer burden and quality of life measures. Assessors will be blind to group allocation. Longitudinal change in balance performance will be evaluated in a sub-study, in which the first 64 participants of the control group with mild to moderate severity Alzheimer's disease, and 64 age and gender matched healthy participants will be re-assessed on all measures at initial assessment, and then at 6, 12, 18 and 24 months. DISCUSSION: By introducing a balance programme at an early stage of the dementia pathway, when participants are more likely capable of safe and active participation in balance training, there is potential that balance performance will be improved as dementia progresses, which may reduce the high falls risk at this later stage. If successful, this approach has the potential for widespread application through community based services for people with mild to moderate severity Alzheimer's disease. TRIAL REGISTRATION: The protocol for this study is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12608000040369).

ItemEnhancing physical activity in older adults receiving hospital based rehabilitation: a phase II feasibility study(BMC, 2012-06-08)BACKGROUND: Older adults receiving inpatient rehabilitation have low activity levels and poor mobility outcomes. Increased physical activity may improve mobility. The objective of this Phase II study was to evaluate the feasibility of a randomized controlled trial (RCT) of enhanced physical activity in older adults receiving rehabilitation. METHODS: Patients admitted to aged care rehabilitation with reduced mobility were randomized to receive usual care or usual care plus additional physical activity, which was delivered by a physiotherapist or physiotherapy assistant. The feasibility and safety of the proposed RCT protocol was evaluated. The primary clinical outcome was mobility, which was assessed on hospital admission and discharge by an assessor blinded to group assignment. To determine the most appropriate measure of mobility, three measures were trialled; the Timed Up and Go, the Elderly Mobility Scale and the de Morton Mobility Index. RESULTS: The protocol was feasible. Thirty-four percent of people admitted to the ward were recruited, with 47 participants randomised to a control (n = 25) or intervention group (n = 22). The rates of adverse events (death, falls and readmission to an acute service) did not differ between the groups. Usual care therapists remained blind to group allocation, with no change in usual practice. Physical activity targets were met on weekdays but not weekends and the intervention was acceptable to participants. The de Morton Mobility Index was the most appropriate measure of mobility. CONCLUSIONS: The proposed RCT of enhanced physical activity in older adults receiving rehabilitation was feasible. A larger multi-centre RCT to establish whether this intervention is cost effective and improves mobility is warranted. TRIAL REGISTRATION: The trial was registered with the ANZTCR (ACTRN12608000427370).

ItemNo Preview AvailablePeople With Stroke Who Fail an Obstacle Crossing Task Have a Higher Incidence of Falls and Utilize Different Gait Patterns Compared With People Who Pass the Task(OXFORD UNIV PRESS INC, 2013-03)BACKGROUND: Obstacle crossing is impaired in people following stroke. It is not known whether people with stroke who fail an obstacle crossing task have more falls or whether the gait adjustments used to cross an obstacle differ from those used by people who pass the task. OBJECTIVE: The purposes of this study were (1) to identify whether a group of people with stroke who failed an obstacle crossing task had a greater incidence of falling and (2) to determine whether people who fail an obstacle crossing task utilize different gait adjustments. DESIGN: This was a prospective, observational study. METHODS: Thirty-two participants with a recent stroke were recruited. Participants walked at self-selected speed and stepped over a 4-cm-high obstacle. Performance was rated as pass or fail, and spatiotemporal, center of mass (COM), and center of pressure (COP) data were collected. Prospective falls data were recorded for 20 participants over a 6-month period. RESULTS: The incidence of fallers was significantly higher (incidence rate=0.833) in the group that failed the obstacle crossing task than in the group that passed the task (incidence rate=0.143). The group that failed the task had a slower walking speed and greater normalized separation between the trail heel (unaffected support limb) and COM as the affected lead toe cleared the obstacle. This group exhibited greater normalized times from affected lead toe clearance to landing, unaffected trail toe clearance to landing, and affected trail toe-off to toe clearance. LIMITATIONS: The sample size was small, and falls data were available for only 20 participants. CONCLUSIONS: Obstacle crossing is an important task to consider in people following stroke and may be useful in identifying those at risk of falls.

ItemNo Preview AvailableEffects of a Multifactorial Falls Prevention Program for People With Stroke Returning Home After Rehabilitation: A Randomized Controlled Trial(W B SAUNDERS CO-ELSEVIER INC, 2012-09)OBJECTIVES: To determine whether a multifactorial falls prevention program reduces falls in people with stroke at risk of recurrent falls and whether this program leads to improvements in gait, balance, strength, and fall-related efficacy. DESIGN: A single blind, multicenter, randomized controlled trial with 12-month follow-up. SETTING: Participants were recruited after discharge from rehabilitation and followed up in the community. PARTICIPANTS: Participants (N=156) were people with stroke at risk of recurrent falls being discharged home from rehabilitation. INTERVENTIONS: Tailored multifactorial falls prevention program and usual care (n=71) or control (usual care, n=85). MAIN OUTCOME MEASURES: Primary outcomes were rate of falls and proportion of fallers. Secondary outcomes included injurious falls, falls risk, participation, activity, leg strength, gait speed, balance, and falls efficacy. RESULTS: There was no significant difference in fall rate (intervention: 1.89 falls/person-year, control: 1.76 falls/person-year, incidence rate ratio=1.10, P=.74) or the proportion of fallers between the groups (risk ratio=.83, 95% confidence interval=.60-1.14). There was no significant difference in injurious fall rate (intervention: .74 injurious falls/person-year, control: .49 injurious falls/person-year, incidence rate ratio=1.57, P=.25), and there were no significant differences between groups on any other secondary outcome. CONCLUSIONS: This multifactorial falls prevention program was not effective in reducing falls in people with stroke who are at risk of falls nor was it more effective than usual care in improving gait, balance, and strength in people with stroke. Further research is required to identify effective interventions for this high-risk group.

ItemNo Preview AvailablePeople with stroke who fail an obstacle crossing task have a higher incidence of falls and utilise different gait patterns compared with people who pass the task(American Physical Therapy Association, 2013)Background: Obstacle crossing is impaired following stroke. It is not known whether people with stroke who fail an obstacle crossing task have more falls, or whether the gait adjustments used to cross an obstacle differ from those used by people who pass the task. Objective: To identify whether a group of people with stroke who failed an obstacle crossing task had a greater incidence of falling, and to determine whether people who fail an obstacle crossing task utilise different gait adjustments. Design: This study was a prospective observational study. Methods: Thirty-two participants with a recent stroke were recruited.

Prospective falls data were recorded for 20 participants over a six month period. Results: The incidence of fallers in the group that failed the obstacle crossing task was significantly higher (IR =.833) than the group that passed (IR = .143; p = .007). The group that failed had a slower walking speed and greater normalised separation between the trail heel (unaffected support limb) and COM as the affected lead toe cleared the obstacle. This group exhibited greater normalised times from affected lead toe clearance to landing, unaffected trail toe clearance to landing and affected trail toe off to toe clearance. Limitations: Sample size was small, and falls data were only available for 20 participants. Conclusions: Obstacle crossing is an important task to consider following stroke and may be useful in identifying those at risk of falls.
