Home-based intervention, Exercise, Older adults, Activities of daily living, Mobility, Cognition
Brief summary
The purpose of the research is to evaluate the feasibility and benefits of a six-week hybrid task-oriented resistance exercise program for older adults who have been recently discharged from home health care.
Interventions
BEHAVIORALTask-oriented resistance exercise
The intervention program includes progressive resistance exercise and daily activity exercise, delivered over a six-week period with an ideal frequency of three sessions per week. Progressive resistance exercise will be provided through a combination of in-person and online sessions, while daily activity exercise will be delivered exclusively in person.

Inclusion criteria
* between the ages of 65 and 90 years * community-dwelling * live within a 50-mile radius of the study site with wireless connectivity in the area * mobility limitations as indicated by self-reported of using a mobility aid or having unsteady gait or walking slower than before * cognitive decline as indicated by a score \< 12 on Mini MoCA Version 2.1 * a care partner or adult family member living in the home or nearby * willing to wear an activity tracker during the study period
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Short Physical Performance Battery | Baseline, 8 weeks, and 12 weeks. | The score ranges from 0 to 12, with a score of 12 indicating the best physical functioning of the lower extremity. |
| Montreal Cognitive Assessment | Baseline, 8 weeks, and 12 weeks. | The score ranges from 0 to 30, with a score of 30 indicating the best global cognitive function. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Timed Up and Go Test-Single Task. | Baseline, 8 weeks, and 12 weeks. | Time in seconds to complete the test, with a longer time indicating poor functional mobility. |
| Timed Up and Go-Dual Task | Baseline, 8 weeks, and 12 weeks. | Time in seconds to complete the task, a longer time indicating the interference of the dual task effect on mobility. |
| List Sorting Working Memory Test | Baseline, 8 weeks, and 12 weeks. | The raw score ranges from 0 to 24, with a higher score indicating better working memory. The raw score is converted to a Change Sensitive Score. |
| Dimensional Change Card Sort Test | Baseline, 8 weeks, 12 weeks. | The raw score ranges from 0 to 30, with a higher score indicating better executive function. The raw score is converted to a Change Sensitive Score. |
| Flanker Inhibitory Control and Attention Test | Baseline, 8 weeks, and 12 weeks | The raw score ranges from 0 to 30, with a higher score indicating better executive function and attention. The raw score is converted to a Change Sensitive Score. |
| Pattern Comparison Processing Speed Test | Baseline, 8 weeks, and 12 weeks | The raw score ranges from 0-133, with a higher score indicating better processing speed. The raw score is converted to a Change Sensitive Score. |
| Speeded Matching Test | Baseline, 8 weeks, 12 weeks | The score ranges from 0 to 130, with a higher score indicating better speed of processing. The raw score is converted to a Change Sensitive Score. |
| Oral Symbol Digit Test | Baseline, 8 weeks, and 12 weeks | The raw score ranges from 0 to 143, with a higher score indicating better processing speed. The raw score is converted to a Rasch score. |
