Frailty assessment: combining clinical review, timed tests, and movement measures

What does frailty mean in clinical care?

When a pre-operative assessment shows slower walking, the key question is whether that finding reflects one mobility problem or reduced reserve across several domains. Frailty describes a distinct clinical state involving reduced physiological reserve and greater vulnerability to stressors, so the assessment needs more context than a walking speed alone.

Frailty can involve physical, cognitive, functional, psychological, social, and medical deficits. Weakness, reduced activity, cognitive change, several long-term conditions, or loss of independence may sit within the same clinical picture, although the mix differs between people and care settings.

Frailty is not an inevitable consequence of ageing, although its risk increases with longevity. Frailty can overlap with disability and multimorbidity without being identical to either one, and an isolated mobility measure cannot represent every domain involved.

Frailty prevalence varies by population and setting. Frailty prevalence ranges from 4% to 16% among community-dwelling older adults and over 40% in clinical subgroups.

Fried and colleagues’ 2001 study reported frailty prevalence of 6.9% in its community-dwelling population, with prevalence increasing with age and higher in women than men. In that study, the frailty phenotype predicted falls, worsening mobility or daily-activity disability, hospitalisation, and death over three years; adjusted hazard ratios ranged from 1.29 to 2.24.

Which signs make frailty relevant to care planning?

Frailty signs include weakness, exhaustion, slow gait, poor balance, reduced activity, weight loss, cognitive impairment, falls, impaired mobility, incontinence, mood changes, sensory impairment, and polypharmacy.

The frailty phenotype uses five criteria: weakness, slowness, low physical activity, exhaustion, and unintentional weight loss. Meeting three or more criteria is the threshold used in that phenotype, while other approaches assess a wider group of health deficits.

Frailty is associated with falls, disability, impaired mobility, hospitalisation, functional decline, and mortality. The 2025 Australian Restorative Care Pathway Clinical Guidelines state that approximately 21% of Australians aged 65 years and above are frail, with likelihood increasing with age; an American Family Physician review published in 2021 reported that frailty affects 5% to 17% of older adults.

Frailty is also relevant to pre-operative assessment because reduced biological reserve and physiological resilience can increase vulnerability around elective and emergency surgery. The CPOC-BGS perioperative guideline links frailty with complications and reports more frequent adverse postoperative outcomes among older people, especially during emergency surgery.

Frailty information can support orthopaedic care, post-operative recovery, and neurological rehabilitation when teams connect functional findings with the wider care plan.

How can frailty change over time?

Frailty can change over time. Pre-frail symptoms may progress, while appropriate clinical measures may help prevent progression or support reversal.

The Cardiovascular Health Study reported a four-year frailty incidence of 7.2% in its cited population. That figure describes new frailty over four years in the study population; it does not provide a fixed duration that applies to every care setting.

Frailty trajectories can also be clinically significant over shorter review periods. In the same study, the frailty phenotype independently predicted falls, worsening mobility or activities-of-daily-living disability, hospitalisation, and death over three years.

A changing trajectory makes the timing and context of follow-up important. We offer a baseline assessment before surgery as a reference point for future assessments, and we generate a structured report that builds on previous assessments to provide targeted and longitudinal insights into patient progress.

What should a clinical frailty assessment bring together?

A clinical frailty assessment brings together more than one score or task. There is no single agreed operational definition or simple assessment tool, and we commonly assess frailty using questionnaires and physical tests carried out by trained care teams.

A phenotype-based approach focuses on features such as weakness, slow walking, exhaustion, low activity, and unintentional weight loss; Fried and colleagues’ 2001 phenotype used 10 pounds of unintentional weight loss in the past year as one criterion. A frailty index uses the proportion of assessed deficits that are present and should include at least 30 deficits, according to the review Frailty in Older Adults.

A comprehensive geriatric assessment provides a wider clinical frame. An interprofessional geriatric health team may review comorbidities, polypharmacy, daily activities, fall risk, hearing, vision, mental health, and cognition so that the care plan reflects function as well as disease.

Recent health history helps separate acute illness from an established frailty pattern. When performance may be affected, the review Frailty in Older Adults recommends asking about health status in the recent past, such as two weeks before assessment, alongside the person’s current status.

The named tool and its contents belong in every result record because different frailty tools can produce inconsistent results.

What does the Timed Up & Go add?

The CDC STEADI Timed Up & Go adds a supervised mobility task to clinical screening. A person rises from a standard armchair, walks to a line 3 metres, or 10 feet, away, turns, walks back, and sits down while an assessor uses a stopwatch.

The CDC STEADI tool says that an older adult who takes at least 12 seconds to complete the Timed Up & Go is at risk for falling. The time is one part of the result, so the assessor also observes postural stability, gait, stride length, sway, pace, balance, arm swing, turning, shuffling, and assistive-device use.

The Timed Up & Go requires supervised testing.

A timed test contributes a focused mobility observation rather than a complete frailty picture. Traditional fall-risk assessment combines screening questions with timed tests, and results can vary between assessors. Interpret the result with the named test, its stated sequence, the recorded time, and the observed gait and balance features. We’re used in hospitals and rehabilitation for assessments during recovery and before discharge.

What can a camera-based movement measure add?

A camera-based movement measure adds a recorded movement measure to screening questions, timed tests, observed movement, clinical review, and care planning. It does not replace fall-risk assessment, and it does not stand alone as a diagnosis or care decision.

Objective movement measures become more useful when the team defines the comparison before collecting them.

A baseline gives later measurements a clear reference point. We provide longitudinal insights by comparing results from before surgery through each stage of recovery, and our structured report builds on previous assessments to show targeted and longitudinal information about patient progress.

3DGait adds a clinician-facing movement assessment for perioperative and rehabilitation pathways. It uses a short video without calibration or wearables, analyzes it on the device, and returns results in about 2 minutes. We quantify movement before and after surgery and support return-to-activity decisions with 3DGait. 3DGait is FDA-listed (Class II, 510(k)-exempt) and HSA-listed (Class A).

How can a service fit these measures into its workflow?

A service can fit frailty and movement measures into a workflow by keeping the clinical question ahead of the test. For pre-operative assessment, the CPOC-BGS guideline recommends that teams review existing frailty information, reassess and document frailty with a validated tool for people over 65 and younger people at risk, record coexisting syndromes, and update functional-status information.

A practical workflow records the conditions that may change how movement is interpreted. Sarcopenia, malnutrition, multimorbidity, and cognitive impairment often coexist with frailty, and the perioperative guideline recommends referral to a team with comprehensive geriatric assessment expertise when CFS is at least 5; where that team is unavailable, it recommends using a frailty intervention tool.

A restorative care pathway adds a service-level screening point. The 2025 Australian Restorative Care Pathway Clinical Guidelines recommend screening for frailty and sarcopenia with validated measurement tools or comprehensive geriatric assessments, and report that approximately 21% of Australians aged 65 years and above are frail.

Care settings can use different points in the pathway: before surgery, during post-operative recovery, before discharge, and during routine community assessment. We support assessment before and after surgery and aid discharge planning for hospitals. Vis-Frailty is a separate CareCam product in clinical study that reports frailty status plus mobility, strength, balance, and fall-risk scores for review alongside clinical assessment. Our structured report builds on previous assessments.

Vis-Frailty serves a different workflow from 3DGait: it is a self-guided population-health screening product in clinical study, while 3DGait is a clinician-facing movement assessment. Vis-Frailty reports frailty status plus mobility, strength, balance, and fall-risk scores; 3DGait uses a short video, analysis on the device, and results in about 2 minutes. This distinction helps a service decide whether it needs broad screening or a clinician-led movement review alongside clinical assessment.

Unlike the Timed Up & Go, which produces a stopwatch result alongside observed gait behaviours during a supervised stand-walk-turn-sit task, 3DGait produces a camera-based movement assessment from a short video, with analysis on the device and results in about 2 minutes. That difference lets a team keep the timed test for its established mobility task while adding a recorded movement result to the same clinical review.

A service-level process also assigns responsibility for follow-up. The RDaSH patient falls manual supports a multi-professional approach and multifactorial assessment to identify contributing factors and plan prevention and injury-mitigation interventions..

What should a team do when findings raise concern?

The first response is to stop any unsupervised or unsafe mobility testing and arrange qualified clinical evaluation promptly. These findings can appear after a stressor event, and impairment in any area reviewed during comprehensive geriatric assessment can be a frailty risk factor requiring further evaluation.

Acute illness can change performance during testing. Gait speed and handgrip strength may be affected by acute illness or impractical in hospital settings, so the team can record current status alongside health status in the recent past, such as two weeks before assessment.

A short history can help identify which areas need fuller review. The self-check described by HealthXchange asks about fatigue, difficulty climbing a flight of stairs, difficulty walking one block, five or more medical conditions, and loss of more than 5% of previous weight in the past six months.

Unsafe mobility, a fall, or observed neurological changes needs a supervised, multi-professional response. The CDC STEADI guidance says changes during the Timed Up & Go may signify neurological problems requiring further evaluation, and a camera-based movement result should remain part of clinical review and care planning.

How should a team document movement assessment results?

Your team’s next decision is to define the care question, the clinical information needed, the supervised test that fits, and the point for follow-up. For a camera-based workflow, record the 3DGait output—such as gait speed, single support time, and knee flexion—with the test conditions and review point; record the Timed Up & Go as its timed stand, walk, turn, return, and sit sequence.

A service can set a baseline before surgery, compare results during post-operative recovery, and use structured reports that build on previous assessments in discharge planning or routine community assessment. We support hospitals and rehabilitation services as well as routine assessments for older adults in primary and community care settings.

A camera-based movement measure supports a clinician’s judgement; it does not make a diagnosis or care decision on its own. A qualified professional decides how individual findings fit the person’s goals, risks, and care pathway.

Start by mapping the decision your service needs to make, then choose the smallest assessment set that answers it and define when the result will be reviewed. That approach keeps frailty assessment connected to patient support, pre-operative assessment, post-operative recovery, and ongoing care.

How should teams compare frailty, timed-test, and movement findings?

Can a Timed Up & Go test diagnose frailty on its own?

No. It provides a focused mobility result and observations such as gait, balance, turning, and assistive-device use. Frailty assessment also considers wider physical, cognitive, functional, medical, psychological, and social factors, alongside recent health and clinical review.

How should teams compare frailty results from different assessment tools?

Record the tool used, its components, the person’s recent health, and the assessment setting. Different tools or modified deficit lists can produce inconsistent results, so scores from separate tools shouldn’t be treated as directly interchangeable.

What should a service record alongside a movement measurement?

Record the care stage, clinical question, recent health status, test conditions, support or walking aid used, and the result. A baseline before surgery can provide a reference for later assessments, while repeat results can show changes during recovery or ongoing care.

What is the difference between frailty screening and a fuller clinical assessment?

Screening identifies people who may need closer review. A fuller assessment examines function, medical conditions, medicines, cognition, nutrition, fall risk, daily activities, and other relevant domains so the care team can plan appropriate patient support.
