カリフォルニア大学サンディエゴ校Strong Foundations 2.0: A Digitally Delivered Fall Prevention Program. (SF2)
Additionally, the investigators hope to showcase it is feasible to sustain programmatic gains with ongoing digitally delivered content by combining cohorts into a larger group that continues to practice the foundational exercises taught during the 12-week initial program.
The primary goal of this program is to reduce fall risk using a digitally delivered exercise intervention with a high level of personalized instruction for the initial portion of the intervention (12 weeks) and to maintain any established reduction in fall risk in an ongoing, pooled cohort extended beyond the initial 12 weeks of training that features a smaller amount of personalized instruction .
The investigators will extend earlier research using a digitally delivered fall-prevention exercise program by engaging 1) two cohorts of up to 15 individuals each at low to average risk of falls and 2) two additional cohorts, of up to 15 individuals with established risk factors for falling identified from the larger San Diego community and a similar number of cohorts/individuals in collaboration with community partners who provide housing for a population from lower socio-economic status, and potentially less access to, and comfort with digital technology. Thus, in total the investigators will enroll up to 120 participants across all sites/settings through this timeframe.
Description of Study Intervention:
Strong Foundations is a 12 week iterative curricular program with three core components: postural alignment and control, balance and mobility, and muscular strength and power. All the exercises offered over the course of the intervention are appropriate for the target population and are standardized so all participants receive the same basic instruction, but level of difficulty is scaled to participant experience, capability, and musculoskeletal limitations.
This fall- risk reduction program, Strong Foundations was designed to be delivered digitally, and while there are many such programs currently available on the internet, especially in the time of COVID-19, the novel feature of this program is the delivery of semi-individualized instruction in real time within a small group setting. This is accomplished largely by use of the 'breakout room' feature on the Zoom platform, where 2-3 trained intern instructors correct form while the lead instructor teaches the larger group. The program was designed with physician input and by exercise physiologists and a Doctor of Physical Therapy candidate, all with extensive training in both group and individualized exercise for geriatric populations.

Change in the scores from the Short Physical Performance Battery (Balance) | Change in composite score and individual scores for all components Summary Score 0-12 with higher values being indicative of better performance. Positive change scores (T2-BL or T1-BL or T2-T1) will be associated with improved performance following intervention.
Gait Speed: Measured in m/sec with higher values being indicative of better performance and lower risk Positive change scores (T2-BL or T1-BL or T2-T1) will be associated with improved performance following intervention 5 repetition chair stands: Scored in seconds with lower values being indicative of better performance and lower risk. Negative change scores (T2-BL or T1-BL or T2-T1) will be associated with improved performance following intervention Balance: 0-10 seconds with higher time indicative of better balance and lower risk. Positive change scores (T2-BL or T1-BL or T2-T1) will be associated with improved performance following intervention | Baseline, 12 weeks (post intervention), 24 weeks (post follow up) |
Change in time to complete the Timed Up and Go (Balance and Function) | Change in the time to complete a standardized assessment of functional mobility and fall risk that times a participant's ability to get up out of chair, walk 8 feet, navigate an obstacle and return to a seated position
Measured in seconds with variable possible length. Faster times are indicative of better performance and lower risk. Negative change scores (T2-BL or T1-BL or T2-T1) will be associated with improved performance following intervention | Baseline, 12 weeks (post intervention), 24 weeks (post follow up) |
Change in postural sway during the Better Balance Testing (Balance) | Changes in the amount of movement (postural sway) observed during a standardized measure of balance on a force platform. This is a well validated measure of proprioceptive and vestibular function utilizing computerized dynamic posturography (i.e. balance board that measures center of pressure and postural sway)
Measured in mm of sway with range 0 - ?. Lower scores are indicative of greater stability and lower risk. Negative change scores (T2-BL or T1-BL or T2-T1) will be associated with improved performance following intervention | Baseline, 12 weeks (post intervention), 24 weeks (post follow up) |
Change in time to complete a 25 foot walk (Balance and function) | Change in time to complete a standardized assessment of gait speed and variability commonly used to assess fall risk.
Measured in seconds to calculate gait speed in m/sec. Lower times (in sec) and higher speeds (in m/sec) are indicative of better function and lower risk. Negative change scores (T2-BL or T1-BL or T2-T1) for time will be associated with improved performance following intervention | Baseline, 12 weeks (post intervention), 24 weeks (post follow up) |
Change in distance covered during a 2.5 minute walk (Aerobic Capacity) | Change in the distance (and estimated aerobic capacity derived from distance) on a standardized walk test to measure aerobic endurance and estimate overall capacity
Measured in meters with variable range. Higher scores are indicative of greater cardiovascular function and lower risk. Positive change scores (T2-BL or T1-BL or T2-T1) will be associated with improved performance following intervention | Baseline, 12 weeks (post intervention), 24 weeks (post follow up) |
Change in Grip Strength (Muscular Strength) | Change in a Standardized assessment to assess muscular strength. Used because it correlates well with overall body strength.
Measured in kg for both hands and averaged with a variable range. Higher scores are indicative of greater muscular strength and lower risk. Positive change scores (T2-BL or T1-BL or T2-T1) will be associated with improved performance following intervention | Baseline, 12 weeks (post intervention), 24 weeks (post follow up) |
Change in number of chair stands completed in 30 seconds (Muscular Strength) | Change in a common field measure associated with fall risk. Used to measure leg strength and endurance specifically. | Baseline, 12 weeks (post intervention), 24 weeks (post follow up) |
