Evidence
Clinicians have long understood the role that mobility plays in healthy aging. Steadion is at the forefront of quantifying and improving mobility health at scale.
Mobility Is A Powerful Health Indicator
Mobility is central to overall health and well being. Changes in gait integrity are strongly associated with negative trends in physical and cognitive health.
Moreover, mobility decline typically speeds the progression of chronic conditions, making the mobility challenged a particularly at-risk population.
Health
Mobility is linked to better health outcomes and lower risk.
Falls
Mobility decline is a strong predictor of falls and injury.
Longevity
Better mobility is associated with longer, healthier lives.
Independence
Mobility enables people to live independently and engage in daily life.
Function
Mobility reflects overall physical function and capability.
Mobility & Health
Mobility health is increasingly recognized as a vital sign, especially in seniors. Research has shown that gait speed, variability, cadence, symmetry, and mobility patterns correlate with frailty, hospitalization, cognitive decline, fall risk, and mortality.
Mobility & Longevity
Mobility is strongly associated with healthy aging and overall health outcomes.
Mobility & Longevity
Gait Speed and Survival in Older Adults
Nine cohort studies found that higher gait speed is consistently associated with longer lives.
The Impact of Mobility Limitations on Health Outcomes in Older Adults
Higher levels of mobility limitations are strongly associated with negative health outcomes. Mobility-enhancing interventions could promote successful aging.
The Association of Gait Speed and All-Cause Mortality
Individuals with the most robust walking speeds have a 43% lower risk of all-cause mortality compared to those with the slowest.
Activity Limitations and Multimorbidity Among U.S. Adults 50 to 64
The relationship between mobility function and chronic conditions isn’t just a concern for seniors.
Mobility & Independence
Mobility decline is one of the earliest indicators of frailty and the #1 reason why seniors lose their indpendence.
Mobility & Independence
Maintaining Mobility and Preventing Disability are Key to Living Independently
Mobility is critical to living independently, and older adults who lose mobility are less likely to remain living at home.
Disability and Caregiving Before and After Long-Term Care Entry
Persons often enter nursing homes or assisted living after months of functional impairment and substantial help at home, usually from unpaid caregivers.
The Effects of Mobility and Cognition on Independence Among Women in Late Life
Mobility and cognition in community-dwelling older women are both strong, independent predictors of the ability to maintain independence.
Mobility & Cognitive Health
As people age, the links between mobility, cognitive and sensory systems come to the fore.
Mobility & Cognitive Health
Physiological Fall Risk Factors Within Cognitive Decline
Cognitively impaired older people are at twice the risk of falls compared to cognitively intact, with approximately 60% falling once or more per year.
Associations Between Gait Speed and Cognition in Older Individuals
Gait speed decline predicts future cognitive decline, independent of variables such as health behaviors and chronic disease.
The Sequence of Decline in Mobility and Cognition Among Initially Unimpaired Older Adults
In older adults, the temporal relationship between gait speed and executive function is bidirectional, with each predicting change in the other.
Mobility Challenges and Falls
Falls are the leading cause of injuries and injury-related deaths in seniors. Numerous technologies can detect and report a fall, but by the time they do, the damage has already been done. The first mission of mobility intelligence is fall prevention.
Falls Epidemiology
Mobility is strongly associated with healthy aging and overall health outcomes.
Falls Epidemiology
Among ages 65 and older in the United States, unintentional falls are the leading cause of injury and injury death.
Older Adult Falls Data, U.S. 2026
While not all falls result in an injury, about 37% who fell reported an injury that required medical treatment or restricted their activity.
Unintentional Fall Deaths in Adults Age 65 and Older
Over the past 20 years, the rates of unintentional fall deaths increased for men and women ages 65 through 85 and older.
Falls & Mobility Aids
Walking aids are essential for the mobility challenged, but they impose challenges of their own.

Assistive Devices for Balance And Mobility: Benefits, Demands, and Adverse Consequences
Mobility aids are significantly associated with falls and injuries, due to attentional, neuromotor, musculoskeletal, and other user demands.
Perspectives on the Use of Mobility Aids in a Diverse Population of Seniors
Many older adults who might benefit from using mobility aids do not or will not use them.
Longitudinal Relationship between Mobility Device Use, Falls and Fear of Falling
In this study, use of canes were significantly associated with falls and fear of falling among robust and pre-frail older adults.
The Economic Impact of Falls
Beyond the human cost, falls place a substantial and growing burden on healthcare systems.
The Economic Impact of Falls
Healthcare Spending for Non-Fatal Falls Among Older U.S. Adults
Total healthcare spending attributable to non-fatal older adult falls has been calculated at over US $80 billion.
Inpatient Trauma Care Costs in the U.S.
A cohort study published by JAMA found that inpatient trauma costs nearly doubled from 2012-2021, with geriatric falls being the primary factor.
Cost of U.S Emergency Department and Inpatient Visits for Fall Injuries in Older Adults
Women and adults 85 years and older accounted for the highest proportion of falls and the highest share of resulting costs.
The Missing Measurement
Although mobility is a recognized indicator of health, it is infrequently assessed, and only during clinic visits, annual wellness exams, or after an adverse event. As a result, meaningful changes in function that develop gradually can go unnoticed for weeks, months or longer.
The Need for Mobility Assessments
These snapshots provide valuable information but leave long periods without objective observation.

An Umbrella Review of Instruments Assessing Gait, Balance, and Functional Mobility
Clinicians use a variety of in-facility tests to assess mobility health and fall risk.
Serial Gait Speed Measurements Over Time and Dynamic Survival Prediction in Older Adults
Both gait speed and its trajectory (increasing/decreasing) are associated with mortality risk.
Association of Clinical Mobility Assessments and Incident Disability
Mobility impairment is a major and modifiable risk factor, and should be mandated as a quality indicator of health for older people.
Important Changes Occur Between Visits
Functional decline is often gradual. Small changes in gait can manifest over time before becoming clinically apparent.

Life-Space Mobility in the Elderly: Current Perspectives
Life-space mobility (LSM) is an evolving concept for assessing patterns of functional mobility over time.
Quality of Daily-Life Gait: Novel Outcome for Trials Focused on Balance, Mobility, and Falls
Clinical tests of balance and mobility can be used as proxies for fall risk in intervention trials. However, they may not reflect an individual’s performance in daily life.
Measured differences indicate that walkers may overperform when tested in professional settings.
Continuous Monitoring: A Paradigm Shift
Continuous gait monitoring can enable timely interventions, before mobility decline becomes a fall, injury, or loss of independence.
Continuous Monitoring: A Paradigm Shift
Data collected from biosensors in the free-living environment may provide a more sensitive indicator of fall risk than in-clinic.
Elucidating the Gaps Between Gait Performance in the Lab and During 24/7 Monitoring
Findings suggest that in-facility measures of gait do not accurately reflect daily-living gait performance.
