Plain English Summary
Background and study aims
Exercise programmes are used to treat patients with a number of chronic diseases and help to improve mobility and physical functioning in older adults. Until now, such programmes targeted either healthy community-dwelling seniors or elderly people living in special residences or care institutions. Chronically ill or mobility restricted people, however, are difficult to reach when they live in their own homes. We have evaluated a new home-based exercise programme, delivered to the participant by an exercise therapist in counselling sessions in the GP’s practice and on the telephone. The aim of this study is to evaluate the effects of the exercise programme on patients’ physical function, physical activity and quality of life.
Who can participate?
Community-dwelling, chronically ill and mobility restricted patients, aged 70 or over, who visit their GP’s practice.
What does the study involve?
Eligible patients will be invited for an assessment in the GP’s practice and randomly allocated to one of two groups. One group will undergo the new home-based exercise programme, delivered by an exercise therapist in counselling sessions in the GP’s practice and on the telephone. The other group will attend counselling sessions promoting physical activities such as light intensity walking.
What are the possible benefits and risks of participating?
Increasing physical activity may initially increase the risk of injuries compared to a sedentary lifestyle. However, in the long term, an increase in physical activity is considered to lead to an improvement in gait and mobility and a reduction of fall and injury risk. For the patients who are eligible for the study, the expected cardiovascular benefit of the programme exceeds the risk for adverse cardiovascular events. To reduce the risk of adverse events, the exercise programme is tailored to the patient’s abilities by an exercise therapist (in cooperation with the GP).
Where is the study run from?
Study management and overall coordination are performed by the Department of Sports Medicine and Sports Nutrition, Ruhr-University Bochum, Germany. The study will take place at about 15 GP practices around the city of Bochum, Germany.
When is the study starting and how long is it expected to run for?
Patients will be enrolled in the study between December 2011 and March 2013, so that the last participant is expected to finish the intervention in June 2013.
Who is funding the study?
The study is funded by the German Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung [BMBF]).

Scientific title
Effects of an exercise programme for chronically ill and mobility restricted elderly with structured support given by the general practitioner's practice (HOMEfit) - a randomized controlled trial
[Effekte eines Bewegungsprogramms für chronisch kranke und mobilitätseingeschränkte Ältere mit strukturierter Unterstützung durch die hausärztliche Praxis (HOMEfit) - ene randomisierte kontrollierte Studie]
Acronym
HOMEfit
Study hypothesis
The objective of this trial is to evaluate the effects of a new multidimensional home-based exercise programme for chronically ill and mobility restricted elderly with structured support given by the general practitioner's (GP) practice on physical function, physical activity, health-related quality of life, fall-related self-efficacy, and exercise self-efficacy.
Main hypothesis:
The new programme (experimental intervention) is more effective in increasing functional lower body strength (measured by a timed test of 5 sit-to-stand cycles [chair rising test]) than the control intervention after 12 weeks.

Condition
Aged, physical inactivity, chronic disease, mobility restriction
Intervention
The duration of the intervention is 12 weeks.
The experimental intervention has been designed according to state-of-the-art physical activity recommendations for older adults (ACSM/AHA 2007). It consists of:
1. Multidimensional (strength, endurance, balance, flexibility) home-based exercise integrating preventive and therapeutic recommendations
2. Consultations provided by an exercise therapist (in the GP's practice and via telephone) including attention, instruction, and methods fostering behavioural change.
The control intervention promotes baseline physical activities, and thus consists of:
1. Baseline activities of daily life, e.g. light-intensity walking
2. Consultations provided by an exercise therapist (in the GP's practice and via telephone) including attention and instruction.
Details of the experimental intervention have already been published in the study protocol of the feasibility study (see Publications). Some modifications have been performed to the programme as a result of quantitative and qualitative analyses.
For all participants, additional medical treatment is permitted before and during the trial except ongoing rehabilitation measures following an inpatient surgical procedure (see exclusion criteria).
