Scientific title

Feasibility of a multidimensional home-based exercise program for the elderly with structured support given by primary care practices: a single arm trial preparing a randomised controlled trial


Study hypothesis

Introduction: physical inactivity and multimorbidity -
Little data exists for the multimorbid elderly concerning their physical activity habits and how to change them. Despite the known benefits of physical activity for health, functioning and quality of life, most of the older adults seem to fail existing physical activity guidelines. On the other hand, physical inactivity is one of the primary contributors to functional decline in the elderly. Chronic medical conditions also have been shown to be one of the most potent contributors to functional decline.

Background: physical activity programs -
A multidimensional activity program that includes endurance, strength, balance, and flexibility training is generally considered to be optimal for older adults. Activities should be tailored to the individual to ensure maximal enjoyment with the goal of optimising adherence (American College of Sports Medicine [ACSM]/American Heart Association [AHA] 2007). In addition, participants receiving high-intensity counselling increase physical activity over a longer period than other groups. The authors concluded that partnering primary care providers with specialised exercise counsellors for age- and health-appropriate physical activity counselling is effective.

Aim of the study:
On the individual level: to develop a physical activity program according to the ACSM guidelines
On the institutional level: to initiate a cooperation between primary care physician and exercise specialists, recruiting and supporting participants
On the methodological level: to analyse the feasibility and functional effects of the programme, and the adherence of the participants, thus gaining preliminary data for the preparation of a randomised controlled study

This trial belongs to subproject 4 of PRISCUS, a joint research programme on prerequisites for a new health care model for elderly people with multimorbidity. Using a previous framework, the present study belongs to phase II and is to prepare a phase III study.

Physical inactivity and multimorbidity


The intervention program lasts 12 weeks. It consists of physical activity counselling and a home-based multidimensional activity program that has been developed according to current recommendations on physical activity in older adults (ACSM/AHA 2007). Every participant is instructed and supervised by his/her personal exercise therapist. Every exercise therapist holds a bachelor of sports science or a higher sports science degree. The exercise therapist provides an initial introduction (theoretically and practically) into the program (week 1), a given number of additional personal consultations within the practice of the participant's primary care physician (week 2, 4 and 6) and a given number of consultations on the telephone (week 3, 5, 7, 9 and 11).

Physical activity counselling:
Every participant receives standardised counselling by the exercise therapist pertaining to the benefits of physical activity. The counselling is aiming to improve knowledge and understanding of the preventive and therapeutic effects of physical activity on particular chronic conditions. The counselling also contains a systematic assessment of the actual physical activity status, a discussion of potential barriers, problem solving to overcome barriers (e.g. by creating an activity timetable), and the creation of individual physical activity goals. Every participant receives the German Olympic Sports Federation workbook 'Bewegungsangebote 70 plus' (Deutscher Olympischer Sport Bund, 2009) that contains information about physical activity programs for seniors.

Activity program:
The program consists of two main components that should be performed in alternating order:
1. A combination of home-exercises to improve strength, flexibility and balance (3 days per week)
2. Walking for exercise to improve aerobic capacity (4 days per week)

Based on the assessment of the actual physical activity habits of the participant, the exercise therapist adapts the activity program to the participant's abilities and needs and to his readiness to exercise. The activity program usually starts with a selection of a few simple exercises and with short walks. Additional exercises are taught by and by with the progression of the intervention. The duration of the walks is also increased in a stepwise manner. Every participant is taught (theoretically and practically) by his/her exercise therapist to correctly perform the home-exercises. A pictorial guidebook (including contact information for the exercise therapist and a statement of the physical activity goal) is provided to each participant to assist them in correct exercise performance. Days of rest are accepted according to the patient's needs. Patients are instructed to record their daily activity (activity log).

1. Home-exercises:
1.1. Strengthening exercises (10):
In order to train all major muscle groups, strengthening exercises comprise a combination of three lower body exercises, one core exercise and six upper body exercises.

Every exercise can be performed in two different variations: less intensive ('basic') or more intensive ('intensive'). Some exercises are to be performed using an elastic resistance band (Thera-Band® GmbH, Dornburg-Frickhofen, Germany). Depending on the performance and the progress, participants can be instructed to increase intensity by resistance advancing to the next color of elastic band (yellow band = lower resistance; red band = higher resistance). The level of effort should be moderate (5 or 6 on a 10-point scale, where no movement is 0, and maximal effort of a muscle group is 10). Participants should perform 3 sets of 15 repetitions of every exercise. They are instructed to not hold their breath during the exercises in order to prevent exercise induced blood pressure elevations.

1.2. Flexibility exercises (4):
Flexibility exercises (stretching) comprise two upper body and two lower body exercises. Participants are instructed to perform the exercises slowly, holding each position for approximately 15 seconds. They are instructed to stretch to a point of moderate tension without pain in the joints or muscles, gradually increasing the range of motion.

1.3. Balance exercises (2):
The program comprises two balance exercises that can be performed in two different variations ('basic' or 'intensive') depending on the participant's abilities.

2. Walking:
To improve aerobic capacity, participants are instructed to walk for exercise (around their homes) four times a week for 30 minutes. The level of effort should be moderate (5 or 6 on a 10-point scale, where sitting is 0 and all-out effort is 10). Depending on the physical activity habits and the abilities of the participant, it can be necessary to start with shorter walks of lower intensity. With the progress of the intervention, duration of the walks and intensity level can be increased in a stepwise manner after talking to the personal exercise therapist. Participants are instructed in the use of a pedometer and asked to begin recording daily pedometer counts.

Consultations with the exercise therapist in the primary care practice:
Within the consultations with the exercise therapist, patients get the opportunity to discuss problems with the exercise program. Exercises are controlled for correctness. New exercises are taught. Choice and intensity of exercises is adapted to performance level. The activity log is discussed. The consultations aim to improve knowledge and self-efficacy of the participants so that they are able to perform their activity program independently. Support is reduced in a stepwise manner and personal consultations are replaced by telephone consultations.
