Detaljerad beskrivning
Background: Inability to walk outdoors restricts full participation in physical activity and community living for older adults that can reduce health-related quality of life (HRQL). Older adults report limited outdoor walking with only 8% achieving the Canadian recommendation for older adults of 150 minutes of moderate-to-vigorous (MV) intensity physical activity per week. Known barriers to walking outside include fear, physical disability due to chronic disease, the appropriateness of footwear and walking aids, the physical environment, weather and temperature. Group practice walking outdoors in locations with variable environmental challenges has the potential to improve physical ability, confidence, outdoor and overall physical activity and social participation. The extent to which it is safe and feasible to implement this intervention in people with varying degrees of physical ability, preferences for where to walk, neighbourhood walkability, and to measure outdoor walking activity, is unclear.
Objectives: The study purpose is to evaluate the feasibility of a randomized controlled trial (RCT) protocol designed to evaluate the effectiveness of an education and skills workshop plus a 3-month outdoor walking group (GO-OUT program) compared to the workshop alone in improving outdoor walking activity. Specific objectives are to characterize participants; determine the feasibility of recruitment; estimate withdrawal rates and the safety and feasibility of the study protocol; obtain preliminary effect sizes; identify the optimal measure of outdoor walking activity based on validity, reliability, effect size and data completeness; and identify participants' and intervention facilitators' perceptions of the challenges and benefits of the intervention and evaluation tools.
Methods: Design and Participants-A feasibility RCT with an embedded qualitative component is proposed with 18 participants. Ambulatory older adults living in the community who report walking outdoors ≤20 minutes/week will be stratified by level of walking impairment (gait speed<0.8 m/s vs ≥0.8 m/s) and randomly assigned to receive the GO-OUT program or the workshop alone. Group allocation will be concealed. A blinded evaluator will evaluate participants at baseline, 3 and 6 months. At 6 months, focus groups of participants from the GO-OUT and workshop groups and intervention facilitators, will participate in a semi-structured interview to explore perceived benefits and challenges of adherence, intervention strategy and outcome measures. Interventions-The workshop will include activity stations at which people will learn about appropriate footwear, walking aids and equipment (pedometers, Nordic poles), goal setting, physical activity recommendations/benefits and practice walking-related tasks. The GO-OUT program will include the workshop plus the outdoor walking group. The walking group will be supervised and consist of 9 participants; they will meet twice a week for 1 hour to walk in increasingly challenging environments to achieve individualized goals. Outcome Measures-Outdoor walking (primary outcome) will be measured by 2 methods: outdoor walking items of the Community Health Activities Model Program for Seniors (CHAMPS) (self-report) and accelerometer/Global Positioning System (GPS). Overall physical activity (secondary outcome) will be measured with the CHAMPS (self-report) as well as accelerometry. Measures of aerobic capacity, walking competency, mood, participation, and HRQL will also be administered. Neighbourhood walkability will be assessed with the Neighbourhood Environment Walkability Scale (self-report). Analysis-This is a feasibility study; therefore, no hypotheses will be tested. The analysis will include describing participant characteristics, estimating recruitment, withdrawal and adverse event rates, estimating preliminary effect sizes for outcome measures, estimating test-retest reliability of outdoor walk time derived from the CHAMPS and construct validity and data completeness of outdoor walk time derived from the CHAMPS and accelerometry/GPS. A qualitative descriptive approach will be used to analyse the interview data. Conclusion-Increasing outdoor walking is expected to help people improve physical activity, the ability to live independently in the community, and health and well-being. This study will evaluate the feasibility of a trial protocol aimed at improving outdoor walking. Findings will be used to justify and inform planning of a future definitive multi-site trial.

Beskrivning
Inclusion Criteria:
- self-reported ability to walk continuously on a flat surface a distance of ≥1 block (~50 metres or 164 feet) independently with or without a walking aid and without supervision
- outdoor walking limitation defined as self-reportedly accumulating ≤20 minutes of outdoor walking in a typical week
- mental competency indicated by a score of ≥18 on the telephone version of the Mini-mental State Exam
Exclusion Criteria:
- active walkers defined as accumulating ≥100 minutes of total (indoor and outdoor) walking per week
- have had ≥2 falls in the prior 12 months or present with an acute fall (based on American Geriatric Society fall guidelines)
- cardiac, respiratory, peripheral vascular or other health conditions that would prevent safe and full participation in the interventions
- currently receiving rehabilitation treatment such as physical or occupational therapy for goals related to walking
- postural hypotension determined by measuring lying and standing blood pressure
- severe limitations to visual acuity by a falls prevention screen
- resting heart rate under 45 or over 100.
The PAR-Q+ (an evaluation of exercise readiness) will be completed by each participant. With participants' permission, their family physician will be asked to review the PAR-Q+ and confirm readiness to participate in exercise.

Experimentell: GO-OUT program
An outdoor walking workshop with stations to learn various outdoor walking skills and information, followed by a supervised, group based outdoor walking program, twice a week for 60 minutes, for 3 months.
|
Participants attend the walking workshop followed by a 3-month outdoor walking group intervention, twice weekly for 60-minutes.
Each session includes a 10-minute warm-up and cool down, and a planned walk in an outdoor community environment.
Continuous walking exercise will gradually increase from 10 to 60 minutes, as well increase difficulty.
Balance exercises will be included in the warmup and walk.
There will be a variety of surfaces and environmental factors to challenge the participants, e.g., carrying objects, diverting the walker's attention, crossing at a light, walking up and down curbs, slopes, and level or uneven surfaces.
Supervision will be on a 1:3 facilitator-to-participant ratio to allow for assistance and individualization of the intervention where necessary.
|
Aktiv komparator: Task-oriented outdoor walking workshop
An outdoor walking workshop with stations to learn various outdoor walking skills and information.
|
The 1-day workshop will be 5 hours with breaks.
Participants will complete a series of stations learning information, strategies and skills related to safely walking outdoors.
Stations include: pedometer use; walking pole use; footwear; footcare; fall prevention; balance exercises; proper use of walking aids; correct posture; self-management of exercise intensity; goal setting; and walking safely outdoors.
Participants will receive a workbook with Canadian Physical Activity Guidelines, benefits of outdoor walking, information for each workshop station and a pedometer.
Participants will use the workbook as an information resource and to record their community ambulation goals, planning routes, and walking time.
All participants will be encouraged to walk outside with a partner, for safety.
