The Frail Older People-Activity and Nutrition study in Umeå
ISRCTN ISRCTN31631302
DOI 10.1186/ISRCTN31631302
ClinicalTrials.gov identifier
EudraCT number
Public title The Frail Older People-Activity and Nutrition study in Umeå
Scientific title The Frail Older People-Activity and Nutrition study in Umeå: a cluster-randomised controlled trial
Acronym FOPANU
Serial number at source N/A
Study hypothesis 1. A high-intensity functional exercise program will improve balance, gait ability, and lower-limb strength in the short- and long-term
2. An intake of protein-enriched energy supplement immediately after the exercises will increase the effect of the training
3. The high-intensity functional exercise program will reduce dependence in mobility and personal care and increase activity and will have a positive effect on depressive symptoms and psychological wellbeing, in the short- and long-term, and will increase safety and reduce falls
4. The exercise program is applicable and is perceived as positive by the participants

Target number of participants 191
Interventions Exercise intervention:
The exercise intervention was based on the High-Intensity Functional Exercise Program (the HIFE Program). The program included functional exercises consisting of everyday tasks challenging leg strength, postural stability, and gait ability. The physiotherapist selected exercises for each participant according to their functional deficits. All exercises were performed in weight-bearing positions, e.g., squats, turning trunk and head while standing, and walking over obstacles. The participants were encouraged by the physiotherapists to exercise with a high intensity and to increase load and difficulty progressively, considering changes in function and health status. Strength exercises were intended to be performed at 8 - 12 repetition maximum. Balance exercises were intended to challenge the participant's postural stability fully. In co-operation with a staff member, at the end of the exercise period, physical tasks were introduced with the purpose of maintaining physical function.

Control activity:
The control activity program included activities while sitting, e.g., watching films, reading, singing, and conversation. The program was based on themes, e.g., the old country shop, famous persons, and games from the past, and was expected to be interesting and stimulating for older persons including those with severe cognitive impairment.

Nutrition intervention and placebo:
The nutrition intervention consisted of a protein-enriched energy supplement. The supplement was a milk-based 200 ml drink that contained 7.4 g protein, 15.7 g carbohydrate, and 408 kJ per 100 g. The placebo drink (200 ml) contained 0.2 g protein, 10.8 g carbohydrate, and 191 kJ per 100 g. Both drinks were served in the same type of non-transparent package and had similar flavours.

Procedure:
The exercise intervention and the control activity started in March 2002, and was performed in groups of three to nine participants supervised by two physiotherapists (exercise) or one occupational therapist (control). The sessions lasted approximately 45 minutes and were held five times every two weeks for three months (13 weeks), in total on 29 occasions. The nutrition drinks were offered within five minutes after each session.
Primary outcome measure(s) 1. Balance ability by Berg balance scale, at 3 (end of intervention period) and 6 months
2. Gait ability by 2.4 metre timed test, self-paced and maximum speed, at 3 and 6 months
3. Lower-limb-strength by 1 Repetition Maximum in a leg-press machine, at 3 and 6 months
Secondary outcome measure(s) 1. Attendance, adverse events and, for the exercise group, intensity achieved, by a structured report developed for this study and completed by the supervisors after each session
2. Participants perception of participating and their perception of changes due to the activity, by a questionnaire developed for this study and for the exercise group also by an interview
3. Staff's perception of participants' changes in function by questionnaire developed for this study, at 3 months
4. Dependence in mobility and personal care by the Barthel ADL Index, at 3 and 6 months
5. Activity by the Life Space Diameter and by questions developed for this study, at 3 and 6 months
6. Falls followed-up in six months from the end of intervention period and perceived balance ability and risk of falling by questions developed for this study, at 3 and 6 months
7. Depressive symptoms and psychological wellbeing by Geriatric Depression Scale (GDS-15) and Philadelphia Geriatric Centre Morale Scale, respectively, at 3 and 6 months
8. Mobility by the Chair-stand test and the Timed up and Go, at 3 and 6 months
9. Muscle mass by bioelectric impedance and by anthropometry, at 3 and 6 months
10. Nutritional status by Mini Nutritional Assessment, body weight, and BMI, at 3 and 6 months
11. Mortality, diseases, and hospital admission, by reviewing participants' hospital records and death certificates in 2 years from the end of the intervention
12. Effect among people with dementia or with depression (compared to those without), respectively, on the primary outcome measures, ADL, and falls
13. Explanatory sub-group analyses of the effect on the primary outcomes, ADL, falls and attendance and motivation during exercise sessions. Independent variables: Barthel ADL Index, Mini-Mental State Examination, Life Space Diameter, BMI, Mini Nutritional Assessment, Berg Balance Scale, body composition by bioelectric impedance and by anthropometry, depression, dementia, previous stroke, drugs, age, sex, self-perceived health, perceived balance ability and risk of falling, perceived possibility of exercise effect and attitude towards the exercise
