This study investigates the use of wearable devices and a sleep diary for tracking sleep and its impact on cognition and balance in older adults over six weeks. It will include routine mobility, balance assessment, and cognitive evaluations, focusing on analyzing the relationships between sleep, mobility, balance, and cognition.
The study is designed to assess the relationships between sleep quality, balance capabilities, and cognitive functions in older adults. Using a longitudinal approach, participants will be monitored over six weeks with the help of wearable technology (OURA ring) and standardized assessments. Weekly in-person visits will include balance assessments using the Mini-BESTest and mobility tests such as the Timed Up and Go (TUG) test. Cognitive functions will be evaluated using the NIH Toolbox Cognitive Battery. The study aims to identify key sleep indicators that influence balance and cognition, ultimately contributing to improved strategies for maintaining the health and well-being of older adults.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Oura ring | All participants will be assigned to a single group receiving a smart ring paired with their phone monitoring sleep and daily activity. |
Not provided
| Measure | Description | Time Frame |
|---|---|---|
| Total Sleep Time | Total Sleep Time will be monitored using the OURA ring, calculated as the sum of all sleep stages in minutes each night. Data will be aggregated to provide a daily and weekly average for each participant. | 6-week daily assessments |
| Sleep Onset Latency | Sleep Onset Latency, defined as the time taken to transition from wakefulness to sleep, will be recorded by the OURA ring each night. Data will be shown in daily and weekly for each participant. | Daily assessments over 6 weeks |
| Sleep Efficiency | Sleep Efficiency will be measured as the ratio of total sleep time to time in bed, expressed as a percentage. The OURA ring will track this nightly, and the data will be summarized as daily data points and a weekly average. | Daily assessments over 6 weeks |
| Cognitive Function | Evaluated using the NIH Toolbox Cognitive Battery, with attention to memory, attention, and processing speed. | 6 weeks weekly assessments |
| Measure | Description | Time Frame |
|---|---|---|
| Berg Balance Scale (BBS) Score | The Berg Balance Scale (BBS) will be administered twice, at baseline and at the end of the study period (Week 6), to assess changes in balance performance. The Berg Balance Scale (or BBS) is a widely used clinical test of a person's static and dynamic balance abilities. | Pre-intervention (Baseline) and Post-intervention (Week 6) |
| Measure | Description | Time Frame |
|---|---|---|
| Demographic Variables | Demographic data, including age, gender, pre-existing conditions, and medical history, will be collected at the baseline (before the intervention begins). This data will be used to analyze participant characteristics and potential correlations with outcome measures. | Week 1 one time measured |

| Mini-BESTest Score | The Mini-BESTest will be conducted weekly throughout the 6-week study period to evaluate changes in balance performance over time. This test measures dynamic balance, functional mobility, and gait. | Weekly assessments over 6 weeks |
| Daily Step Count | Daily step count will be monitored using the OURA ring. The data will be aggregated daily and weekly for each participant to assess overall physical activity levels. | Daily assessments over 6 weeks recorded by Oura ring |
| Toe Strength from ToeScale | Measured using the ToeScale for both flexion and extension strength, comparing baseline and post-intervention data. | 6 weeks weekly assessments |
