Feasibility, safety and preliminary evidence of the effectiveness of a home-based exercise programme for older people with Alzheimer's disease: a pilot randomized controlled trial.

OBJECTIVE: To evaluate the feasibility and safety of a home-based exercise programme for people with Alzheimer's disease, and to provide preliminary evidence of programme effectiveness in improving balance and mobility and reducing falls risk. DESIGN: A randomized controlled trial. SETTING: Community. PARTICIPANTS: Forty people with mild to moderate Alzheimer's disease (mean age 81.9, SD 5.72; 62.5% female). INTERVENTIONS: Participants were randomized to a six-month home-based individually tailored balance, strengthening and walking exercise programme (physiotherapist) or a six-month home-based education programme (control) (occupational therapist). Both programmes provided six home-visits and five follow-up phone calls. MAIN MEASURES: Balance, mobility, falls and falls risk were measured at baseline and programme completion. Intention-to-treat analysis using a generalized linear model with group allocation as a predictor variable was performed to evaluate programme effectiveness. Feasibility and adverse events were systematically recorded at each contact. RESULTS: Fifty-eight per cent of the exercise group finished the programme, completing an average of 83% of prescribed sessions, with no adverse events reported. Functional Reach improved significantly (P = 0.002) in the exercise group (mean (SD), 2.28 (4.36)) compared to the control group (-2.99 (4.87)). Significant improvement was also observed for the Falls Risk for Older People - Community score (P = 0.008) and trends for improvement on several other balance, mobility, falls and falls risk measures for the exercise group compared to the control group. CONCLUSIONS: The exercise programme was feasible and safe and may help improve balance and mobility performance and reduce falls risk in people with Alzheimer's disease.

Factors influencing commencement and adherence to a home-based balance exercise program for reducing risk of falls: perceptions of people with Alzheimer's disease and their caregivers.

BACKGROUND: Balance exercise is an important component of falls-prevention interventions, with growing evidence that it can be beneficial for people with Alzheimer's disease (AD). However, to implement a balance exercise program successfully for people with AD it is important to consider factors that can affect commencement and adherence to the program. This qualitative study explored these factors. METHODS: Ten participants with AD, who had completed a six-month home-based balance exercise program, and their caregivers (n = 9) participated. A phenomenological theoretical framework with semi-structured interviews was used for data collection and analysis. RESULTS: Factors influencing the decision to commence the program were: possible benefits of the program, recommendations from health professionals, value of research, positive attitude towards exercise, and minimizing caregivers' burden. Factors influencing adherence to the program were grouped under 11 themes: six themes facilitated completion (program characteristics, physiotherapist, exercise recording sheet, caregivers' support, sense of commitment, and perceived benefit) and five themes were barriers (pre-existing conditions, dislike of structured exercise, absence from home, caregiver's health or commitment, and bad weather). CONCLUSIONS: A home-based exercise program with regular support from a physiotherapist and caregiver are key elements facilitating continuing program adherence in people with AD.
