SuPA Mobility: Supporting Physical Activity for Mobility in Mobility-Limited Older Adults

The goal of this randomized controlled trial is to investigate the effectiveness of a health-coaching intervention to improve physical activity in older adults with limited mobility when compared to a control, health education group.

About this study

A total of 290 older adults with limited mobility will be randomized to either a 26-week health coaching program or health education program. Outcomes will be assessed at baseline, 13-weeks, 26-weeks (end of intervention), and 52 week (6-month follow-up period).

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • scored ≤ 9/12 on the SPPB
  • are able to complete the 400-m walk in ≤ 15 minutes without sitting or physical assistance from another person or walker (use of cane is acceptable)
  • scored 22/30 or higher on the Mini-Mental State Examination (MMSE)
  • have no significant functional impairment as indicated by a score of 6/8 or higher on the Lawton and Brody Instrumental Activities of Daily Living Scale
  • are able to safely engage in MVPA as indicated by the PAR-Q+ and by the family or study physician as necessary
  • are community-dwelling
  • are able to provide written informed consent.

Exclusion criteria

  • are diagnosed with dementia or stroke
  • self-report engaging in MVPA ≥ 10 minutes per week in the prior 3 months
  • are unable to understand, speak, and read English proficiently

Treatment and study plan

Health Coaching Program

Behavioral

The HC program will be delivered over 26-weeks. Participants will have an initial hour-long HC session where the BAP coach will conduct a brief physical assessment and work with the participant to establish their physical activity goals and develop a plan. After the initial consult, coaches will conduct 8 x 20-minute phone calls with participants over the 26-week trial decreasing from bi-weekly phone calls in weeks 1-12 to monthly phone calls in weeks 13-26.

Participants in the HC group will have an overall goal of increasing their weekly participation in moderate to vigorous physical activity by 50 minutes, via 5-, 7-, or 10-minute bouts of progressive exercises, at a rate of perceived exertion range of 13-14 ("somewhat hard") by week 16. Participants will have access to specific exercise sessions made available by YouTube and/or hardcopy manuals created by the research team.

Other names: HC

Health Education Program

Behavioral

Participants will begin with a one-hour, group-based, interactive education session on falls prevention delivered either in-person or by Zoom. Following the initial education session, ED participants will receive additional group education sessions (in-person or by Zoom) with the same duration and schedule as the HC program covering a variety of healthy aging topics.

Other names: ED
