226 The Feasibility and Acceptability of Perturbation-Based Balance to Older Adults in Rural Communities

OBJECTIVES/GOALS: Older adults in rural communities are at an elevated risk of falling. Perturbation-Based Balance Training (PBT) is a highly effective fall prevention paradigm but its feasibility in the community is unknown. The purpose of this study was to determine the feasibility and acceptability of PBT to older adults and local clinicians in rural communities. METHODS/STUDY POPULATION: 19 older adults (60+ years) were recruited from communities in rural Montana to take part in a PBT program. The PBT program was implemented using a bespoke portable PBT treadmill developed by our research team and validated against commercial PBT treadmills. To increase ecological validity, the program was implemented by local clinicians. The PBT program lasted 6 weeks, with 1 session per week, participants received up to 35 trip perturbations per session. The feasibility and acceptability of PBT to participants and clinicians was assessed within the Theoretical Framework of Acceptability, prospectively and retrospectively via interviews and surveys, and concurrently via field notes. RESULTS/ANTICIPATED RESULTS: Data analysis is ongoing and will be complete by the time of presentation. Preliminary results suggest the portable PBT program was generally acceptable to older adults and local clinicians. Perceived effectiveness was generally positive and increased balance awareness and low burden are emerging as common themes. Local clinicians indicated the burden of implementing PBT was low, PBT fit within their views on fall prevention, and had a high level of perceived effectiveness. There appear to be a few limitations to feasibility, which are primarily related to the weight and transportation of the treadmill. We are currently working to refine the treadmill and lower its weight and are developing a grant with local clinicians and extension agents that would facilitate transportation to a broader network of communities. DISCUSSION/SIGNIFICANCE: Our preliminary findings suggest PBT is feasible in rural communities and accepted by older adults. Increased balance and fall awareness and low burden are emerging as important factors in the feasibility and acceptability of PBT. This study provides a foundation for future studies to translate other PBT modalities from the lab to the community.
