Description of intervention(s) / exposure
No intervention.

The systematic review aims to evaluate the extent to which measurement of participation has been reported in randomised controlled trials of fall prevention interventions that contain exercise.

The meta-analysis consists of trials that measured participation at baseline and follow-up. The meta-analysis aims to determine whether exercise interventions targeting falls increase International Classification of Functioning, Disability and Health (ICF) participation in older people.

The systematic review and meta-analysis will include randomised controlled trials which include an exercise intervention of any duration. Exercise is defined as an intervention meeting the Prevention of Falls Network Europe (ProFaNE) category of exercise (supervised or unsupervised). (ProFaNE subcategories are gait, balance, co-ordination, functional tasks, strength/resistance, flexibility, 3D (tai chi, qui Gong, dance, yoga), general physical activity, endurance, other kinds of exercises. Exercise may be delivered either in isolation or as a component of a multifactorial intervention or a multiple intervention.

Outcomes
Primary outcome [1] 259307 0
To evaluate the proportion of falls prevention trials, with an exercise intervention, that have measured participation outcomes.

*Participation is defined in the International Classification of Functioning, Disability and Health (ICF) as "involvement in life roles".

Method for identifying measures of participation:
For each included study, all reported outcome measures will be collected on a data extraction form. Measurement instruments potentially measuring the ICF category of participation will be identified if they were designed to measure the societal consequences of health conditions, health related quality of life or generic health. Copies of all measurement instruments potentially measuring participation will be acquired. The instruments items will be linked to the ICF using established linking rules.(1) In order to determine if the ICF concept of participation is measured, the instruments will be assessed against the following instrument selection criteria.(2,3): 1) inclusion of at least three domains from chapters 3-9 of the activities and participation sections of the ICF; 2) designed for community use. Instruments meeting these criteria for participation will be included if they were self or interview administered, generic and constructed for adults. The use of ICF terminology is not essential. In addition to instruments developed to address the concept of participation, instruments developed using related conceptual models (eg. handicap, community integration) will be included if they meet the inclusion criteria. Instruments will be classified as health-status instruments if they contained multiple ICF concepts, such as the EuroQol (EQ-5D), SF-12 and World Health Organization Disability Assessment Schedule II (WHODAS II).

Timepoint [1] 259307 0
Data collected at baseline in the individual trials. Data will be analysed at the conclusion of this systematic review.
Primary outcome [2] 259311 0
Use meta-analysis to evaluate whether exercise interventions targeting falls increase participation in older people.
Timepoint [2] 259311 0
Data collected at baseline and the first time point after the conclusion of the intervention in the individual trials.

If a trial reports results of more than one participation outcome, only one outcome will be included in the meta-analysis, with measures incorporating the individual's perception of their participation prioritised over measures assessing frequency of activities.

We will record either the pre and post mean and standard deviation scores, the mean and standard deviation change from baseline scores or the raw scores. The standardised mean difference with 95% confidence interval will be calculated.
Secondary outcome [1] 265738 0
To determine which measurement instruments are used to measure participation in falls prevention trials that include an exercise intervention.
Timepoint [1] 265738 0
Data collected at baseline in the individual trials. Data will be analysed at the conclusion of this systematic review.
Secondary outcome [2] 265747 0
To assess the association between type of intervention (exercise only or multi-faceted / multifactorial with an exercise component) and estimates of the effect of intervention on participation.
Timepoint [2] 265747 0
Data collected at baseline and the first time point after the conclusion of the intervention in the individual trials. Data will be analysed using meta-regression analysis at the conclusion of this systematic review.

Eligibility
Key inclusion criteria
For the systematic review:
- Randomised controlled trials and quasi-randomised trials.
- Studies that specify participants were aged 60 years or over; studies that clearly recruited participants described as older people, elderly or senior; or in the case of trials including younger participants with a specific diagnosis (e.g. stroke), participants had a mean age minus one standard deviation of over 60 years.
- Studies with interventions that include exercise, delivered either in isolation or as a component of a multifactorial intervention or a multiple intervention.
- Studies that report outcome measures that evaluate number of falls, rate of falls or number of fallers.

For the meta-analysis:
- Trials that measured participation at baseline and at least one time point after conclusion of the intervention.
