Study summary

In the Lifestyle-Integrated Functional Exercise (LiFE) program, exercises to increase strength and improve balance are embedded into daily life activities. Recurring daily activities and tasks are used as prompts for these exercises so that they are performed multiple times per day. However, implementing the original LiFE program includes high financial requirements and human resources as it comprises one-to-one supervision of participants. Therefore, it is investigated whether implementing LiFE in groups (gLiFE) is not inferior to the individually delivered LiFE (iLiFE) in terms of reducing falls per physical activity. In addition, gLiFE is expected to be more cost-effective as compared to iLiFE. In a multicenter non-inferiority trial, 300 participants aged 70 years or older with confirmed fall risk will be randomized into either the iLiFE or gLiFE arm of the study. Both arms will undergo the same strength and balance exercises and habitualization strategies as described in the LiFE program, however, based on different approaches of delivery (i.e., group vs. individual).

Read the detailed description

The "Lifestyle-integrated Functional Exercise" (LiFE) program aims to promote safe indoor and outdoor mobility. It differs from classical exercise programs in that it trains and encourages participants to embed up to 15 balance and strength exercises into daily recurring tasks performed as part of the daily life routine. The LiFE program simultaneously aims at preventing falls and promoting an active lifestyle in older adults. As LiFE requires 1:1 supervision by trainers who administer LiFE exercises during seven visits in the participants' homes, it is both time consuming and resource intensive and therefore not suitable for widespread implementation. Hence, the aim of this study is to compare a group-delivered LiFE intervention (gLiFE) with the original LiFE intervention (iLiFE). More specifically, gLiFE is tested for its non-inferiority compared to iLiFE in terms of:

  • Effectiveness: The gLiFE program is not less efficacious than the established iLiFE program in terms of reducing fall incidence expressed as number of falls per amount of physical activity (e.g., steps).
  • Retention rate: The gLiFE program does not result in a lower intervention retention rate (i.e., percentage of the sample completing the 6-month and 12-month follow-up assessment) as compared to the iLiFE program.
  • Implementation: Delivering the gLiFE program is less costly and more cost-effective than delivering the iLiFE program.

In a multicenter non-inferiority trial, participants (n = 300; > 70 years; confirmed fall or high risk of falling) will be randomized into either the individual iLiFE (seven home visits) or gLiFE (groups up to twelve persons; seven group sessions).

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

MMSE and MoCA

Short tests of memory and thinking, each scored out of 30. Lower scores suggest more difficulty; criteria give a range, either to include people with memory problems or to leave them out.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

Study arms

  • Active comparator
    individual LiFE (iLiFE)

    In iLiFE, LiFE activities to increase strength, improve balance, and promote physical activity as well as habitualization strategies are introduced and taught in 7 highly individualized, one-to-one home visits.

    Behavioral: iLiFE

  • Experimental
    group LiFE (gLiFE)

    In gLiFE, the same LiFE activities as performed in iLiFE are introduced and taught in 7 group sessions with 8 to 12 participants. Implementation and habitualization strategies will be addressed within the group setting, making use of group dynamics and processes.

    Behavioral: gLiFE

Interventions

  • BehavioraliLiFE

    In the individual LiFE (iLiFE), the program is taught in seven visits in the individuals' homes within eleven weeks. Participants are supervised in a face to face situation by one qualified trainer (physiotherapist or sports scientist). Each home visit takes between 1 and 1.5 hours. A total of five balance exercises, seven strength exercises for the lower extremities, and two exercises to increase physical activity are taught. In addition to the home visits, all participants receive two 'booster telephone calls' within the remaining weeks until the 6-month follow-up assessments.

  • BehavioralgLiFE

    The group-based LiFE (gLiFE) program consists of seven group sessions (n = 8-12 participants) which are held over the course of eleven weeks, with a maximum duration of 2 hours per session. Each session is led by two qualified trainers (physio therapists or sports scientists), i.e., one main and one co-trainer. In all group sessions, trainers will teach the participants how to perform and integrate the LiFE program, i.e., LiFE balance and strength activities into their daily routines. After the group sessions have ended, participants will receive two 'booster telephone calls' within the remaining weeks until the 6-month follow-up assessments.

Ran from Apr 2018 to primary completion in Aug 2020, 28 months.

Of 5,147 non-industry interventional studies with no phase under Motor Activity, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 36. This study's 28 months is above that.

Counting every sponsor, half of 5,207 studies reached it within 17 months; a quarter within 7 and three quarters within 36.

Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
