Remote Balance Training for Individuals With Dementia

Remote Online Administration of Otago Exercise Program for Individuals With Dementia and Their Care Partners: A Feasibility Study

Individuals with dementia (IwDs) fall more and are more seriously injured in falls than their age-matched, cognitively intact peers. An accessible and sustainable fall prevention program would be of great value. Using remote technology has become commonplace during the COVID-19 pandemic, and Marymount University's new Center for Optimal Aging plans to use this technology to bring a web-based version of a well-established and accepted evidence-based fall prevention intervention, the Otago Exercise Program, into the homes of IwDs and their care partners. Care partners will be trained in the home for safety and oversight of their exercising partner with dementia. Dyads of IwD and care partners will access the online exercise program through an online Learning Management System (Canvas) three times per week which tracks their access to exercise videos. Once per week, exercise will take place in a Zoom format with a small cohort of other dyads, supervised by a research team member, and the other two times will be independent access of exercise videos. The purpose of this study is to determine the viability of remote administration of the Otago Exercise Program by assessing program functionality, utility, and effectiveness. Feasibility will be evaluated by using components of the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, and Maintenance). The results will guide and inform adaptations of future remote training efforts for IwD, with implications at the individual, family, and societal levels.

Detailed Description

Methodology Overview:

This 16-week prospective study will examine feasibility of remotely administered Otago Exercise Program (OEP) for Individuals with Dementia (IwD) supervised by their care partners (n=24 dyads) using select components of the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, and Maintenance). Specifically, data on program adherence, system usability, enjoyment, and adverse events will inform the ability of Marymount Center for Optimal Aging to work with partners to Adopt and Implement this programming for the older adult community. Additionally, this within-subject design study will assess measures of balance, mobility, falls, cognition, & confidence to assess preliminary data on Effectiveness, should the program be feasible. Finally, Reach will be evaluated by comparing demographic data of participants recruited as compared to the target local community, which is broadly diverse in terms of age, race, ethnicity, economic status, health status, culture, and language.

Existing studies demonstrate that home based exercise for IwD with care partners are feasible and safe, providing there is careful orientation to safety measures and continued support and follow up over the course of the study. Inclusion/exclusion criteria are designed to avoid inclusion of very high risk fallers (i.e., use of assistive device).

All assessments will be performed in the participant's home with oversight by a licensed physical therapist (PT) with geriatric expertise. A PT/PT student team will be assigned to each dyad for the duration of the study and the team will have regular contact with the dyad to direct activities, discuss questions and concerns, and provide support over the initial 8-weeks of the study, and waning contact over the final 8-weeks of the study. Students will be vetted and trained by the PTs. A detailed procedures manual describing all testing, remote exercise administration, and data collection procedures will be followed by all research team members.

After an enrollment visit and consent, pre-test assessment, and education/safety training for home exercise (Week 0), IwD with care-partner supervision will participate in remote OEP (3x/week x 8 weeks) with 1x/week synchronous/real time with an online research team instructor and small group (<3) of other dyads. The other sessions (2x/wk) will be carried out independently by dyads using pre-recorded videos of exercises without live instruction. Following completion of the 8-wk OEP, immediate post-testing (Week 8) will occur.

For Weeks 9-16, dyads will be encouraged to continue with OEP videos 3x/week, but there will no longer be synchronous/research team supervised sessions. There will be continued weekly opportunity to meet with other dyad participants via Zoom. Study personnel will contact dyads via phone/email/zoom (per participant preference) to provide encouragement and answer questions. The frequency of contact will fade over Weeks 9-16: Weekly for Weeks 9-10; every other week for Weeks 11-14; and only as requested for Weeks 15-16 (i.e., when the participant initiates contact). Delayed post-testing will occur following Week 16.

Specific Procedures and Intervention:

Enrollment Visit: An Enrollment visit will be scheduled after phone screening which will include: (1) Care partner screening to assure ability to safely oversee exercise program; (2) Answer any questions & procure signed consent; (3) Intake demographic & medical data; (4) Education re: location & set up for safe exercising; and (5) Introduction to remote platforms for use during study.

Home Visit 1 @ Week 0: Includes: (1) Data collection of outcome measures for pre-OEP; (2) Review Canvas & Zoom platform access; (3) Review education re: location & set-up for safe exercising; and (4) Provide OEP manual and calendar/diary.

OEP Intervention (remote supervision 1x/week, independent dyad exercise 2x/week) Weeks 0-8: The research team will work with dyads (during preparation, synchronous sessions & weekly check-ins) to assure safety as the top priority and to encourage maximal participant challenge during exercise sessions. OEP will be administered via a web-based learning management system (Canvas). The Canvas site set-up will be simple, with two links, one for the synchronous classes (1x/week) and one for asynchronous classes (2x/week). Synchronous classes (3-4 dyads) will be carried out using a video conferencing application (Zoom) with oversight by a research team member. A video of OEP exercise will run on the shared screen throughout the exercise activity. The videos instruct safe progression of exercises. Participant dyads will access asynchronous online OEP sessions twice per week independently with videos accessed through Canvas. Participant dyads will receive weekly check-in calls/emails/Zoom meetings (based upon participant preference) from their PT / student team to stay connected, share falls diary data, and have an opportunity to ask questions.

Home Visit 2 @ Week 8: Includes: (1) Data collection of outcome measures for post-OEP-1; and (2) Data collection for feasibility measures-1 with dyads.

OEP Intervention (independent dyad exercise 3x/wk) Weeks 9-16: Participants are encouraged to continue to perform OEP 3x/wk without direct supervision by research staff. Fading frequency of check-ins over the course of weeks 9-16, but continued opportunity and encouragement to communicate on Zoom with other participant dyads and discuss OEP experience. These opportunities will occur weekly at the shared Zoom link at agreed upon times for the small group of dyads that had exercised together during weeks 0-8.

Home Visit 3 @ Week 16: Final home visit includes: (1) Data collection of outcome measures for post-OEP-2; and (2) Data collection for feasibility measures-2 with dyads.

Data Management & Analysis:

All research team members, including students, will be educated in research ethics, participant privacy, and data confidentiality, and will act accordingly in the context of data management. Data collection in the home will occur using password protected tablet with electronic forms. Participants will be assigned a Research ID number which will be associated with their data. Research ID numbers associated with direct identifiers will be stored separately from collected data, and personal health information will be kept to a minimum. Data used for analysis will be de-identified. Data shared in publications or presentations will be presented in aggregate or summary form such that no individuals are identifiable. Publication / presentation of data shall be consistent with normal scientific practices.

Feasibility data will be evaluated with some measures compared to a priori thresholds and others evaluated descriptively. Adherence data will be compared to mean adherence rates (proportion of classes attended) for falls prevention programs for older adults, which is 66%. System Usability Scale (SUS) scores will be assessed relative to a priori target score of >65, as modeled by others using remote technology with a similar population. Adverse events, PACES-8 (enjoyment) and BSFC (caregiver burden) data will not have a priori thresholds, but will be descriptively presented and compared to other studies. Functional tests (30sCST, TUG) will be assessed with paired t-tests to determine immediate intervention impact (Week 0 vs Week 8), and with Repeated-measures ANOVA across 3 testing sessions (Week 0, Week 8, Week 16); non-parametric 4-stage balance test will be evaluated with Wilcoxon test (Week 0 vs Week 8) and with Friedman test across 3 sessions, and with attention to the identified threshold score (marking high to lower fall risk).

Intervention / Treatment

Experimental: Remote Otago Exercise Program; Individuals with dementia will participate in Otago Exercise Program in their home using video recordings and with safety oversight by their trained care partners.

Other: Otago Exercise Program; The Otago Exercise Program (OEP) is a CDC endorsed evidence-based falls prevention program for older adults. It has not been well studied with individuals with dementia. It is comprised of a brief "warm up"/flexibility series, lower extremity strengthening, and balance exercises. The same menu of exercises is used for all participants, but exercises are progressed based upon individual performance. For the purposes of this study, three 25-minute video recorded versions of OEP will be rotated for use, all of which include brief flexibility activities, strengthening, and balance exercises. Strengthening exercises will be limited to body weight resistance for ease of instruction, safety, and consistency. Balance exercises involve changes in base of support in static and dynamic contexts, with challenge progressively increased by decreasing arm support during training (from 2-hands, to 1-hand, to no hands).; Other Names: Modified Otago Exercise Program
