Rehabilitation for Individuals with Dementia: Facilitating Success

Effectiveness of physical rehabilitation on physical functioning and quality of life for long-term care residents with dementia: a systematic review and meta-analysis

OBJECTIVE

The objective of this review was to evaluate the effectiveness of physical rehabilitation versus non-rehabilitation comparators on physical functioning and quality of life for long-term care (LTC) residents with dementia.

INTRODUCTION

LTC residents living with dementia often have impaired physical functioning and quality of life. Physical rehabilitation can improve physical functioning and quality of life for individuals living with dementia; however, many LTC residents with dementia do not receive physical rehabilitation and providers are unsure what interventions to employ. A synthesis of studies examining physical rehabilitation will help guide practice in the LTC sector where most residents live with dementia. Previous syntheses have focused on all residents in LTC, specific professions, interventions, or people with dementia in the community. Our review focuses on LTC residents with dementia and a broader definition of physical rehabilitation.

INCLUSION CRITERIA

This review includes studies that evaluate physical rehabilitation in comparison with non-rehabilitation controls among LTC residents with any severity of dementia. We included studies that measure the effect on activities of daily living, performance-based physical functioning, and self- or proxy-rated quality of life.

METHODS

Searches were conducted in APA PsycINFO (EBSCOhost), CINAHL (EBSCOhost), PubMed (National Library of Medicine), Embase, Scopus, and the Cochrane CENTRAL database with no date or language limitations. Two independent reviews assessed the studies against the inclusion criteria. Two independent reviewers extracted data and conducted a quality assessment using a structured extraction form. Certainty of evidence was ascertained using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. Where possible, studies were pooled in meta-analyses; otherwise, a narrative synthesis was performed.

RESULTS

Thirty-three studies were included (n = 3072 participants); 27 were randomized control trials and the remaining 6 were non-randomized trials. The overall risk of bias of the included studies was low to unclear. Many of the included studies focused on increasing activity or walking, while few were individually tailored or at an intensity appropriate to induce therapeutic effects on physical function. Physical function was also measured via several outcome measures, limiting our ability to pool results. There was low certainty evidence that physical rehabilitation improved activities of daily living (12 RCTs, 1348 participants, SMD 0.78; 95% CI 0.27 to 1.30) and the Short Physical Performance Battery Score (3 RCTs, 258 participants, MD 3.01 points; 95% CI 1.37 to 4.66) compared with non-rehabilitation interventions. There was low to moderate certainty evidence that physical rehabilitation demonstrated no change in the 30-Second Sit to Stand Test (2 RCTs, 293 participants, MD 0.79 repetitions; 95% CI -0.45 to 2.03), 6-Minute Walk Test (4 RCTs, 363 participants, MD 17.32 meters; 95% CI -29.41 to 64.05), gait speed (4 RCTs, 400 participants, MD 0.10 meters/seconds; 95% CI -0.02 to 0.22), Timed Up and Go Test (3 studies, 275 participants, MD -2.89 seconds; 95% CI -6.62 to 0.84), or quality of life (4 RCTs, 419 participants, SMD 0.20; 95% CI -0.08 to 0.47).

CONCLUSIONS

This review demonstrates that physical rehabilitation may improve activities of daily living for LTC residents living with dementia, though the evidence is of low certainty. The effect of physical rehabilitation on specific functional tasks, like gait speed and quality of life, are less clear. Future research should examine the effects of individualized, progressive interventions on outcome measures that reflect the capacity and preferences of LTC residents with more advanced dementia.

Neural Underpinnings of Learning in Dementia Populations: A Review of Motor Learning Studies Combined with Neuroimaging

The intent of this review article is to serve as an overview of current research regarding the neural characteristics of motor learning in Alzheimer disease (AD) as well as prodromal phases of AD: at-risk populations, and mild cognitive impairment. This review seeks to provide a cognitive framework to compare various motor tasks. We will highlight the neural characteristics related to cognitive domains that, through imaging, display functional or structural changes because of AD progression. In turn, this motivates the use of motor learning paradigms as possible screening techniques for AD and will build upon our current understanding of learning abilities in AD populations.

Influence of Sex on Cognitive and Motor Dual-Task Performance Among Young Adults: A Cross-Sectional Study

OBJECTIVE

To investigate the sex-related differences in single-task performance through motor torque, cognitive tasks and walking speed, and the combined dual-task costs (DTCs) considering both motor and cognitive performance in young adults.

METHODS

Sixty-seven non-athletic subjects 37 females and 30 males were enrolled. The study measured their knee extension muscle torque using an isokinetic strength dynamometer and their walking speed using the one step app. these assessments were performed both with and without a cognitive task, and the DTCs were calculated.

RESULTS

The females exhibited significantly larger motor performance dual task effect through (torque-DTC, speed-DTC) compared with males while exhibiting smaller cognitive dual task effect with muscle torque and speed.

CONCLUSION

Deterioration in motor performance during muscle force production and speed during dual tasks was large in females compared to males, whereas males experience a decline in cognitive ability when performing dual tasks compared with females.

Resident-, family-, and staff-identified goals for rehabilitation of long-term care residents with dementia: a qualitative study

BACKGROUND

Long-term care (LTC) residents with dementia can benefit from rehabilitation to improve function and quality of life. However, specific goals for rehabilitation with this population are not always clear. The purpose of this study was to describe the goals for rehabilitation for LTC residents with dementia from the perspective of residents, family, and staff.

METHODS

This was a phenomenological qualitative study. LTC residents with moderate to severe dementia, family members, and staff were recruited from two LTC homes in Halifax, Nova Scotia. Data were collected through semi-structured interviews and field notes from observations with residents while they were being active within the home. Data were analyzed via the principles of thematic content analysis, mapped onto the International Classification of Functioning, Disability, and Health (ICF) Model, and reported by the participant group (i.e., residents, family, or staff).

RESULTS

The 15 participants were three female residents aged 82 to 98 years, seven predominantly (86%) female family members aged 56 to 74 years, and five staff members (two females, three males, aged 22 to 55 years) who were physiotherapists, a physiotherapy assistant, a healthcare aide, and a registered licenced practical nurse. Most identified goals fell within the activities and participation constructs of the ICF model and focused on maintaining or improving function, mobility, and quality of life. Specific themes included preventing falls, walking or locomoting, stair climbing, maintaining activities of daily living, engaging in enjoyable exercise, maintaining independence and human connections, keeping busy, leaving the home for activities, and participating in group activities.

CONCLUSIONS

Rehabilitation goals for LTC residents living with dementia often focus on quality of life and functional activities and participation in LTC and family activities and events. Function and quality of life are interrelated, whereby functional goals influence quality of life. While some goals focus on improvement in function, maintenance or prevention of decline were also key elements. Future work should ensure rehabilitation interventions are developed relative to individually identified goals, and interventional success is measured in relation to the goal.

Adapted Home-Based Exercises in Dementia: An Exploratory Pre-post Pilot and Feasibility Study

The goals of this exploratory pre-post pilot and feasibility study (NCT04916964) were to assess the feasibility and effectiveness of an adapted Test-and-Exercise home-based exercise program on basic functional mobility and executive functions in persons with prodromal or mild Alzheimer's disease. Participants followed an 8 week exercise program at home, once per week with a physiotherapist and twice per week with their usual caregiver or independently. Functional mobility and executive functions were assessed before and after the intervention. Feasibility criteria were recruitment opportunity, participation agreement rate, cost adequacy, and drop-out rate. Twelve participants aged 80.83 ± 4.65 years took part in the study. All the basic functional mobility measures showed small effect sizes. Concerning executive functions, 5 measures showed small to moderate effect sizes. The 4 feasibility criteria were met. A larger scale study would, however, need adaptations and prior research on the ability of this population to use touch-screen technology.

Physiotherapy students' experiences of working with people with dementia during their clinical placements: a qualitative study

PURPOSE

To explore the experiences of physiotherapy students on working with people with dementia during their clinical placements.

METHODS

Qualitative study using a Web-based survey of students in a 2-year entry-level Masters of Physical Therapy (MPT) program. Students were asked to reflect on their experiences during clinical placements within the MPT program. Qualitative content analysis was used to analyze the survey responses.

RESULTS

A total of 55 students (93%) completed the survey. Two overarching themes were mastery and inequity. Mastery described dementia care physiotherapy as a complex and potentially rewarding area of practice, requiring education and development throughout the professional continuum from student to expert. Inequity captured the barriers people with dementia experience to receiving excellent physiotherapy care. Six categories supported the themes: 1) physiotherapist characteristics for a successful therapeutic relationship; 2) communication strategies; 3) best practice physiotherapy skills and knowledge; 4) education strategies; 5) desire to work with people living with dementia; and 6) equity.

CONCLUSIONS

The study found physiotherapy students' experiences were informed by the preceptors' approach to delivery of care for people living with dementia. The students also articulated areas they wish they had known before placement and provided suggestions for teaching development in this area.

A Clinical Perspective on Bespoke Sensing Mechanisms for Remote Monitoring and Rehabilitation of Neurological Diseases: Scoping Review

Neurological diseases including stroke and neurodegenerative disorders cause a hefty burden on the healthcare system. Survivors experience significant impairment in mobility and daily activities, which requires extensive rehabilitative interventions to assist them to regain lost skills and restore independence. The advent of remote rehabilitation architecture and enabling technology mandates the elaboration of sensing mechanisms tailored to individual clinical needs. This study aims to review current trends in the application of sensing mechanisms in remote monitoring and rehabilitation in neurological diseases, and to provide clinical insights to develop bespoke sensing mechanisms. A systematic search was performed using the PubMED database to identify 16 papers published for the period between 2018 to 2022. Teleceptive sensors (56%) were utilized more often than wearable proximate sensors (50%). The most commonly used modality was infrared (38%) and acceleration force (38%), followed by RGB color, EMG, light and temperature, and radio signal. The strategy adopted to improve the sensing mechanism included a multimodal sensor, the application of multiple sensors, sensor fusion, and machine learning. Most of the stroke studies utilized biofeedback control systems (78%) while the majority of studies for neurodegenerative disorders used sensors for remote monitoring (57%). Functional assessment tools that the sensing mechanism may emulate to produce clinically valid information were proposed and factors affecting user adoption were described. Lastly, the limitations and directions for further development were discussed.

Effectiveness of physical rehabilitation in improving physical functioning and quality of life for long-term-care residents with dementia: a systematic review protocol

OBJECTIVE

The objective of this review is to evaluate the effectiveness of physical rehabilitation versus non-rehabilitation control in improving physical functioning and quality of life in long-term care residents with dementia.

INTRODUCTION

Many long-term-care residents live with dementia and have impaired physical function and poor quality of life. Physical rehabilitation can improve physical function and quality of life for people living with dementia, yet many long-term-care residents with dementia do not receive this intervention, and health care providers are unsure of which rehabilitation interventions are effective. Studies synthesizing effective rehabilitation programs are needed to guide practice in the long-term-care sector where many residents live with dementia. Previous studies have focused broadly on long-term care, specific professions, interventions or outcomes, or people with dementia in the community. Our review will focus on long-term-care residents living with dementia and a broader definition of physical rehabilitation.

INCLUSION CRITERIA

This review will include studies that evaluate physical rehabilitation in comparison with non-rehabilitation controls among long-term-care residents with any severity of dementia. We will include studies that measure the effect on performance-based physical functioning and self- or proxy-reported quality of life.

METHODS

Searches will be conducted in APA PsycINFO (EBSCO), CINAHL (EBSCO), MEDLINE (Ovid), Embase, Scopus, and the Cochrane CENTRAL database with no date or language limitations. Two independent reviewers will conduct a critical appraisal of eligible studies, assess methodological quality, and extract the data. Where possible, studies will be pooled in a statistical meta-analysis.

Education and training interventions for physiotherapists working in dementia care: a scoping review

OBJECTIVES

Physiotherapy plays a key role in many aspects of dementia care, most notably in maintaining mobility. However, there is a lack of dementia care training at undergraduate and postgraduate level, and more importantly, a paucity of evidence as to what constitutes effective dementia education and training for physiotherapists. The aim of this scoping review was to explore and map the evidence, both quantitative and qualitative, relating to education and training for physiotherapists.

DESIGN

This scoping review followed the Joanna Briggs Institute methodology for scoping reviews. A chronological narrative synthesis of the data outlined how the results relate to the objectives of this study.

SETTING

All studies, both quantitative and qualitative on dementia education and training conducted in any setting, including acute, community care, residential or any educational setting in any geographical area were included.

PARTICIPANTS

Studies that included dementia education and training for both qualified and student physiotherapists were considered RESULTS: A total of 11 papers were included in this review. The principal learning outcomes evaluated were knowledge, confidence, and attitudes. Immediate post- intervention scores showed an improvement in all three outcomes. The Kirkpatrick four level model was used to evaluate the level of outcome achieved. Most educational interventions reached Kirkpatrick level 2, which evaluates learning. A multi-modal approach, with active participation and direct patient involvement seems to enhance learning.

CONCLUSIONS

Allowing for the heterogeneity of intervention design and evaluation, some common components of educational interventions were identified that led to positive outcomes. This review highlights the need for more robust studies in this area. Further research is needed to develop bespoke dementia curricula specific to physiotherapy. CONTRIBUTIONS OF THE PAPER.

Dual-Task-Based Music Therapy to Improve Executive Functioning of Elderly Patients with Early Stage Alzheimer's Disease: A Multiple Case Study

Deficits in executive functioning are a common feature of Alzheimer's disease (AD) and result from impairment in the central executive system. As a result, elderly patients with early stage AD may require interventions that are more cognitively intense than traditional interventions. To address this need, in this multiple case study, we explored a dual-task-based music therapy intervention that involved drum playing and singing designed to induce attentional and motor controls. Three octogenarians diagnosed with early stage AD participated in 12 dual-task-based music therapy sessions over 6 weeks. Measures of executive functioning and the performance of a bimanual drum tapping task were evaluated before and after the intervention. Improvements in executive functioning were observed for participants A and C. After the intervention, reduced mean synchronization errors were found for the simultaneous tapping condition for all three participants. Although there was variability in the functional changes between participants, it is noteworthy that positive improvements in the elderly patients with early stage AD were obtained following dual-task-based music therapy. The results suggest that music therapy integrated into the dual-task paradigm can be an effective way to address degenerative cognitive deficits among elderly patients with early stage AD.

The Effects on Gait of 4-Wheeled Walker Use in People with Alzheimer’s Disease Dementia and Gait Impairment: A Pilot Study

In people with dementia, provision of mobility aids is standard treatment for those with impaired gait. However, mobility aid use is independently associated with increased falls risk. In this short communication, gait velocity and stride time variability were recorded in eleven adults with Alzheimer’s disease dementia. Three conditions were tested: single-task (no aid), walking with a walker, and dual-task (walker use and counting backwards) under both a straight path and Figure-of-8 walking configuration. Gait velocity increased when using a walker compared to no aid in the Figure-of-8 walking configuration. Walker use improved gait in simple walking, but benefits diminished upon dual-task.

''We usually choose safety over freedom'': results from focus groups with professional caregivers in long-term dementia care

Background

People with dementia living in nursing homes are mostly sedentary, which is a consequence of various personal, environmental and organizational factors. Until now, studies on physical activity and safety in dementia have focused on residents and caregivers from the viewpoint of (individual) care provision and health benefits. There has been little to no focus on the possible influence of group dynamics between care providers with regard to physical activity and safety. The aim of this study is to gain more insight into the viewpoints and intentions of groups of professional caregivers towards safety and physical activity and the potential influence of the group-oriented setting in long-term care on physical activity of individual residents.

Methods

A qualitative study comprising three focus group discussions including professional caregivers (n = 15) was conducted within two long-term care organizations in the Netherlands. Focus group discussions were structured using an interview guide derived from a preliminary framework, based on existing literature and complemented with clinical expertise.

Results

Seven themes could be derived from the focus group discussions that influence physical activity and safety: 1) Individual health and abilities; 2) Balancing physical activity and safety; 3) Physical restraints; 4) Group interests versus the individual interests; 5) Organization of care and physical environment; 6) Perceived responsibilities and tasks of professional caregivers and 7) Change is challenging.

Conclusions

Due to multiple influencing factors, the balance for care providers in long-term care generally tends towards safety over physical activity. Furthermore, in order to stimulate physical activity various limitations are experienced, including the organization of care, the general health of the residents and difficulty to achieve changes in daily care. Most importantly, the group interests of both the professional caregivers and the residents have a substantial influence on the incorporation of physical activity in daily care.

Dementia in People with Severe/Profound Intellectual (and Multiple) Disabilities: Practice-Based Observations of Symptoms

INTRODUCTION

Observable dementia symptoms are hardly studied in people with severe/profound intellectual (and multiple) disabilities (SPI(M)D). Insight in symptomatology is needed for timely signaling/diagnosis. This study aimed to identify practice-based observations of dementia symptoms in this population.

METHODS

Care professionals and family members were invited to complete a survey about symptoms. Quantitatively analyzed survey data were further deepened through semi-structured interviews with care professionals having vast experience in signaling/diagnosing dementia in this population. Symptoms were categorized using a symptom matrix.

RESULTS

Survey respondents and interviewees frequently observed a decline in activities of daily living (ADL) functioning and behavioral and psychological changes, like increased irritability, anxiety, apathy and decreased eating/drinking behavior. Cognitive symptoms were particularly recognized in persons with verbal communication and/or walking skills. To lesser extent motor changes and medical comorbidities were reported.

CONCLUSION

Increased insight in dementia symptoms contributes to developing a dedicated screening instrument for dementia in people with SPI(M)D.

Feasibility of a Small Group Otago Exercise Program for Older Adults Living with Dementia

Older adults with dementia experience more frequent and injurious falls than their cognitively-intact peers; however, there are no evidence-based fall-prevention programs (EBFPP) for this population. The Otago Exercise Program (OEP) is an EBFPP for older adults that has not been well-studied in people with dementia. We sought to explore the feasibility of group delivery of OEP in an adult day health center (ADHC) for people with dementia. We collected demographic data, Functional Assessment Staging Tool (FAST), and Mini Mental State Exam (MMSE) scores for seven participants with dementia. Pre- and post-test data included: Timed-Up-and-Go (TUG), 30-Second Chair-Stand (30s-CST), Four-Stage-Balance-Test (4-SBT), and Berg Balance Scale (BBS). We implemented a supervised group OEP, 3x/week × 8 weeks. Most participants required 1:1 supervision for optimal challenge and participation. Five participants completed the program. All had moderately severe to severe dementia based upon FAST; MMSE scores ranged from mild to severe cognitive impairment. Four of five participants crossed the threshold from higher to lower fall risk in at least one outcome (TUG, 30s-CST, 4-SBT, or BBS), and four of five participants improved by >Minimal Detectible Change (MDC90) score in at least one outcome. The group delivery format of OEP required significant staff oversight for optimal participation, making the program unsustainable.

Paratonia in Dementia: A Systematic Review

Background:

Paratonia is a dementia-induced motor abnormality. Although paratonia affects virtually all people with dementia, it is not well known among clinicians and researchers.

Objective:

The aim of this study was to perform a systematic review of the literature on the definition, pathogenesis, diagnosis, and intervention of paratonia as well as to propose a research agenda for paratonia.

Methods:

In this systematic review, the Embase, PubMed, CINAHL, and Cochrane CENTRAL databases were searched for articles published prior to December 2019. Two independent reviewers performed data extraction and assessed the risk of bias of the studies. The following data were extracted: first author, year of publication, study design, study population, diagnosis, assessment, pathogenesis, therapy and interventions.

Results:

Thirty-five studies met the inclusion criteria and were included. Most studies included in the review mention clinical criteria for paratonia. Additionally, pathogenesis, method of assessment, diagnosis, and paratonia severity as are interventions to address paratonia are also discussed.

Conclusion:

This systematic review outlines what is currently known about paratonia, as well as discusses the preliminary research on the underlying mechanisms of paratonia. Although paratonia has obvious devastating impacts on health and quality of life, the amount of research to date has been limited. In the last decade, there appears to have been increased research on paratonia, which hopefully will increase the momentum to further advance the field.

The Effects of Different Types of Dual Tasking on Balance in Healthy Older Adults

Numerous of our daily activities are performed within multitask or dual task conditions. These conditions involve the interaction of perceptual and motor processes involved in postural control. Age-related changes may negatively impact cognition and balance control. Studies identifying changes related to dual-task actions in older people are need. This study aimed to determine the effects of different types of dual-tasking on the balance control of healthy older adults. The sample included 36 community-living older adults, performing two tests—a sway test and a timed up-and-go test—in three conditions: (a) single motor task; (b) dual motor task; and (c) dual motor task with cognitive demands. Cognitive processes (dual-task and cognition) affected static balance, increasing amplitude (p < 0.001) and frequency (p < 0.001) of the center of mass displacements. Dynamic balance revealed significant differences between the single motor condition and the other two conditions during gait phases (p < 0.001). The effect of dual-tasking in older adults suggests that cognitive processes are a main cause of increased variability in balance and gait when under an automatic control. During sit-to-stand, turning, and turn-to-sit movements under dual-tasking, the perceptive information becomes the most important focus of attention, while any cognitive task becomes secondary.

Physical and Vestibular Physical Therapy Referrals in People With Alzheimer Disease

People with Alzheimer disease (AD) are at increased risk of falls and disproportionately burdened with vestibular impairment compared with healthy older adults. Although physical therapy (PT) and vestibular physical therapy (VPT) are effective rehabilitation interventions in improving balance and fall risk, referral patterns for these services in the AD population are understudied. A retrospective chart review was conducted of patients seen for primary AD care at a tertiary AD referral center to investigate the frequency of rehabilitation referrals. Of the 801 people with AD seen for AD care in 1 year, 48 individuals (6.0%) were referred to PT and 5 individuals (0.6%) to VPT. People with AD appear to receive very infrequent PT and VPT referrals, despite the potentially large number of people with AD who could benefit from PT and VPT services to improve their balance and vestibular function.

Development, reliability and validity of the Safe Use of Mobility Aids Checklist (SUMAC) for 4-wheeled walker use in people living with dementia

BACKGROUND

Balance and gait problems are common and progressive in dementia. Use of a mobility aid provides physical support and confidence. Yet, mobility aid use in people with dementia increases falls three-fold. An assessment tool of mobility aid safety in people with dementia does not currently exist. The objectives of this study were: 1) to develop a tool for the evaluation of physical function and safe use of a 4-wheeled walker in people with dementia, and 2) to evaluate its construct and criterion validity, inter-rater and test-retest reliability and minimal detectable change.

METHODS

Healthcare professionals (HCP) experienced in rehabilitation of people with dementia participated in focus groups for item generation of the new tool, The Safe Use of Mobility Aid Checklist (SUMAC). The SUMAC evaluates physical function (PF) and safe use of the equipment (EQ) on nine tasks of daily life. Reliability was evaluated by HCP (n = 5) scored participant videos of people with dementia (n = 10) using a 4-wheeled walker performing the SUMAC. Inter-rater and test-retest reliability was assessed using intra-class correlation coefficients (ICC). Construct validity evaluated scores of the HCPs to a consensus HCP panel using Spearman's rank-order correlations. Criterion validity evaluated SUMAC-PF to the Performance-Oriented Mobility Assessment (POMA) gait subscale using Spearman's rank-order correlations.

RESULTS

Three focus groups (n = 17) generated a tool comprised of nine tasks and the components within each task for physical function and safe use. Inter-rater reliability was statistically significant for SUMAC-PF (ICC = 0.92, 95%CI (0.81, 0.98), p < 0.001) and SUMAC-EQ. (ICC = 0.82, 95%CI (0.54, 0.95), p < 0.001). Test-retest reliability was statistically significant for SUMAC-PF (ICC = 0.89, 95%CI (0.81, 0.94), p < 0.001) and SUMAC-EQ. (ICC = 0.88, 95%CI (0.79, 0.93), p < 0.001). As hypothesized, the POMA gait subscale correlated strongly with the SUMAC-PF (r_s = 0.84), but not EQ (r_s = 0.39).

CONCLUSIONS

The focus groups and research team developed a tool of nine tasks with evaluation on physical function and safe use of a 4-wheeled walker for people with dementia. The SUMAC tool has demonstrated content validity for the whole scale and good construct and criterion validity for the SUMAC-PF and SUMAC-EQ. The subscores of the SUMAC demonstrated excellent to good inter-rater and test-retest reliability.

The experiences of people with Alzheimer's dementia and their caregivers in acquiring and using a mobility aid: a qualitative study

PURPOSE

Cognitive deficits and gait and balance problems are progressive in people with Alzheimer's dementia. Yet, mobility aids are associated with an increased falls risk in people with dementia. Our objectives were to identify the perceptions of people living with mild-to-moderate Alzheimer's dementia, and their caregivers, on the use of mobility aids.

METHODS

A qualitative study using semi-structured, face-to-face interviews was conducted. Community-dwelling older adults with dementia attending a day hospital program were recruited. Thematic analysis was conducted and the text was coded into broad themes aligned with the research questions. The coded text was examined for patterns and similarities, and grouped to form inductive themes.

RESULTS

Twenty-four people (12 living with dementia and their 12 caregivers) participated. Five themes were identified: (1) acknowledgement of need; (2) protecting a sense of self; (3) caregiver oversight and relief of burden; (4) healthcare professional involvement; (5) environment and design of aids.

CONCLUSIONS

The findings suggest that people with Alzheimer's dementia and their caregivers regard mobility aid use as increasing independence. There is a role for healthcare professionals to be involved in the prescription, provision and training for use of mobility aids among people living with dementia to ensure uptake and safety.IMPLICATIONS FOR REHABILITATIONMobility aid use is regarded as increasing independence by people with Alzheimer's disease and their caregivers.Falls risk associated with mobility aid use was not well known and caregivers perceived mobility aids as a means to reduce falls.Most people do not see a healthcare professional when they acquire a mobility aid and there is a role for healthcare professionals to be involved in the prescription, provision and training of people living with dementia in the use of mobility aids in order to increase the uptake of aids and their safe use.

Effect of dual-tasking on walking and cognitive demands in adults with Alzheimer's dementia experienced in using a 4-wheeled walker

BACKGROUND

Learning to walk with a 4-wheeled walker increases cognitive demands in people with Alzheimer's dementia (AD). However, it is expected that experience will offset the increased cognitive demand. Current research has not yet evaluated gait in people with AD experienced in using a 4-wheeled walker under complex gait situations.

RESEARCH QUESTION

What is the effect of dual-task testing on the spatial-temporal gait parameters and cognitive performance of people with AD experienced with a 4-wheeled walker?

METHODS

Twenty-three adults with mild to moderate AD (87.4 ± 6.2 years, 48 % female) and at least 6 months of walker use experience participated. Three walking configurations: 1) straight path (SP), 2) Groningen Meander Walking Test (GMWT), and 3) Figure of 8 path (F8) were tested under two walking conditions: 1) single-task (walking with aid) and 2) dual-task (walking with aid and completing a cognitive task). Tri-axial accelerometers collected velocity, cadence and stride time variability (STV). Gait and cognitive task cost were the percentage difference between single-task and dual-task conditions. Two-way repeated measures ANOVAs were used to answer the study question.

RESULTS

A significant interaction between walking configuration and condition was found for velocity (p = 0.002, ω² = 0.36), cadence (p = 0.04, ω² = 0.15) and STV (p < 0.001, ω² = 0.53). Velocity and cadence decreased and STV increased with increasing walking configuration complexity and upon dual-tasking. Dual-task gait and cognitive task cost deteriorated in all walking configurations, but gait was prioritized in the GMWT and F8 configurations. Despite familiarity, experienced walker users with AD exhibit impaired gait when walking in complex situations which increases falls risk. Upon dual-task, individuals with AD self-prioritized a posture-first strategy in complex configurations.

SIGNIFICANCE

Dual-task testing in experienced users results in slower walking, fewer steps and increased STV, which increases falls risk in people with mild to moderate AD and becomes most pronounced in complex environments.

Home-Based Gait Training Using Rhythmic Auditory Cues in Alzheimer's Disease: Feasibility and Outcomes

Background/Purpose: Although gait disorders occur early in the course of Alzheimer's disease (AD) and increase the risk of falling, methods to improve walking in the home setting are poorly understood. This study aimed to determine the feasibility of a home-based gait training program using rhythmic auditory cues for individuals living with mild to moderately severe AD.

Methods: Participants had probable AD with no other major conditions affecting locomotion. The intervention consisted of eight progressively modified 45-min gait training sessions delivered during home visits over 4 weeks. Experienced physiotherapists provided the therapy that incorporated rhythmic music cues for a range of locomotor tasks and ambulatory activities. On the days when the physiotherapist did not attend, participants independently performed a seated music listening activity. Walking speed, cadence, stride length, double limb support duration, and gait variability (coefficient of variation) were measured using an 8-m GAITRite® computerized walkway immediately before and after the physiotherapy intervention. Participant satisfaction was also assessed using a purpose-designed questionnaire.

Results: Eleven (median age, 77.0 years; median ACE III score, 66/100; 3 females and 8 males) community-dwelling adults living with AD participated. Wilcoxon signed rank tests revealed statistically significant increases in gait speed following the home-based physiotherapy intervention (baseline = 117.5 cm/s, post-intervention = 129.9 cm/s, z = −2.40, p < 0.05). Stride length also improved (baseline = 121.8 cm, post-intervention = 135.6 cm, z = −2.67, p < 0.05). There was no significant change in gait variability. The program was found to be feasible and safe, with no attrition. Participant satisfaction with the home-based music-cued gait training was high, and there were no adverse events.

Conclusion: A progressively modified gait training program using rhythmic auditory cues delivered at home was feasible, safe, and enjoyable. Music-cued gait training can help to reduce the rate of decline in gait stride length and speed in some individuals living with AD.

Vestibular Physical Therapy in Individuals With Cognitive Impairment: A Theoretical Framework

Falls are a major health care concern in individuals with Alzheimer disease (AD) and their caregivers. Vestibular impairment is a known risk factor for falls, and individuals with AD have been shown to have an increased prevalence of vestibular loss compared with age-matched controls. Vestibular physical therapy (VPT) is effective in improving balance and reducing fall risk in cognitively-intact persons with vestibular impairment. However, the effectiveness of VPT in improving balance and reducing falls in individuals with AD who have vestibular loss has never been explored. SUMMARY OF KEY POINTS:: In this article, we apply prevailing ideas about rehabilitation and motor learning in individuals with cognitive impairment (IwCI) to VPT. RECOMMENDATIONS FOR CLINICAL PRACTICE:: We propose a modification of current evidence-based VPT protocols for IwCI using the strength-based theoretical framework that emphasizes the motor learning abilities of IwCI. In addition, we highlight the importance of establishing an excellent rapport with IwCI, and present key strategies for optimizing the therapeutic relationship. In ongoing work, we are assessing the efficacy of this modified VPT protocol in IwCI to improve balance and reduce falls.
