Brief summary
Preclinical mobility limitations (PCML) manifest early in the process of declining mobility, and are not typically identified or acted upon by clinicians. These mobility limitations manifest as changes in how daily tasks such as walking are performed (slower speed, lower endurance). Persons in the PCML stage are at increased risk for the onset of disability and chronic disease. Persistent deterioration in mobility is a predictor of mortality and has been reported even in the absence of changes in activities of daily living over a two-year period. Further, older persons with mobility limitations, including reduced gait speed, are at risk for falls. These cumulative transitions of a person's life-long mobility form their mobility trajectory and preventing mobility decline at an early stage along this trajectory is the focus of this research initiative. This study will evaluate a novel intervention, STEPPING-UP, for improving walking ability in persons with PCML.
Interventions
OTHERTelephone-Based Coaching Walking Program
The participants assigned to this group will receive a 12-week Telephone-Based Coaching Walking Program (TELE) delivered by a PT who will help participants set short and long term walking goals.
OTHERChair-Based Yoga Program
Participants assigned to this group will receive a virtual 12-week Chair-Based Yoga Program (YOGA), a group-based exercise control where participants will undertake a seated exercise program that includes: warm up, seated and standing yoga poses, cool down.
OTHERStepping-Up
The intervention group will receive STEPPING-UP, a virtual 12-week, multicomponent intervention that includes tailored task-oriented motor learning exercise and a mobility self-management (SM) program.

Inclusion criteria
1. Community-dwelling 2. Age ≥55-75 years 3. PCML as assessed using a questionnaire that requires respondents to self-report difficulties with their mobility (walking 2.0km). Respondents will be considered in a stage of PCML if they report no task difficulty but report modification of task performance (i.e. modify frequency, method or time to complete the task) 4. Understanding of spoken and written English 5. Own a laptop computer, have an email address and have internet capabilities of running the video-conferencing platform, Zoom©. 6. Resident of Ontario, Canada
Exclusion criteria
1. A score of \<11 on the MoCA 5-Minute telephone screen 2. Major illness that would prevent participation
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Walking speed | Baseline | The 4-Metre Gait Speed Test (4MGS) is a performance-based measure of walking speed. The 4MGS test will be performed from a standing start at both a self-selected (usual) and fastest walking speed. |
| Change in walking speed from baseline | 12 weeks | The 4-Metre Gait Speed Test (4MGS) is a performance-based measure of walking speed. The 4MGS test will be performed from a standing start at both a self-selected (usual) and fastest walking speed. |
Secondary

| Change in walking speed from baseline | 24 weeks | The 4-Metre Gait Speed Test (4MGS) is a performance-based measure of walking speed. The 4MGS test will be performed from a standing start at both a self-selected (usual) and fastest walking speed. |
| Exercise capacity | Baseline | 2-Minute Step Test (TMST): The TMST is a test of exercise capacity that can be used as an alternative to a timed long-distance walking test when assessment space is limited. Individuals are required to march in place as quickly as possible for 2 minutes while lifting their knees to a height midway between their patella and iliac crest when standing. |

| Lower body strength | Baseline | 30-Second Chair Stand Test (CST): The 30-Second CST is used to assess lower body strength and power and is measured by the number of chair stand repetitions in a 30-second period. |

| Change in dual task cost from baseline | 12 weeks | Difference in time between the Timed Up and Go (TUG) and the TUG Cognitive. |
| Self-reported change in mobility | 12 weeks | Global Mobility Change Rating: A single question, ''Since your last visit, has there been any change in your mobility?'' will be asked. The response will be made on a 11-point self-reported Likert scale: - 5 = very much worse; 0 = unchanged; 5 = very much better. |

| Balance self-efficacy | Baseline | Activities-specific Balance Confidence (ABC) Scale: The ABC Scale is a self-report measure of balance confidence. Individuals are asked to rate their confidence in completing 16 common tasks without losing balance, on a scale from 0% (no confidence) to 100% (complete confidence). |

| Mobility patterns | Baseline | The Life-Space Assessment (LSA): The LSA measures a person's usual pattern of mobility during a 1-month period, documenting mobility based on how far and how often a person travels and any assistance required. |
