Tinetti Balance And Gait Assessment (Poma) Calculator

What Is the Tinetti Balance and Gait Assessment (POMA)?

The Tinetti Performance-Oriented Mobility Assessment (POMA), developed by Mary Tinetti in 1986, is a widely validated clinical instrument used to quantify balance and gait function in older adults. Administered by a trained clinician, the Tinetti calculator produces a composite score that stratifies fall risk, guides physical therapy goal-setting, and tracks functional change over time.

The POMA Formula

The total POMA score sums the Balance subscale (POMA-B) and the Gait subscale (POMA-G):

POMA = ΣB_i (i = 1 to 10) + ΣG_j (j = 1 to 8) | Maximum = 16 + 12 = 28 points

The Balance subscale contains 10 items scored 0–1 or 0–2 for a maximum of 16 points. The Gait subscale contains 8 items scored 0–1 or 0–2 for a maximum of 12 points. Higher scores indicate better performance and lower fall risk across both domains.

Balance Subscale (POMA-B): 10 Items, Maximum 16 Points

The balance subscale evaluates static and dynamic balance across seated and standing tasks. Clinicians observe the patient in a hard, armless chair and on a flat surface:

• Sitting Balance — Scores 0 (leans or slides in chair) or 1 (steady and safe)
• Arises from Chair — Scores 0 (unable without help), 1 (uses arms to rise), or 2 (rises without using arms)
• Attempts to Arise — Scores 0 (unable without help), 1 (requires more than one attempt), or 2 (succeeds on the first attempt)
• Immediate Standing Balance (first 5 seconds) — Scores 0 (unsteady), 1 (steady but uses assistive device), or 2 (steady without any aid)
• Standing Balance — Scores 0 (unsteady), 1 (wide stance or uses support), or 2 (narrow stance without support)
• Nudged (eyes open, feet together) — Scores 0 (begins to fall), 1 (staggers or grabs), or 2 (steady)
• Eyes Closed (feet together) — Scores 0 (unsteady) or 1 (steady)
• Turning 360° — Steps — Scores 0 (discontinuous steps) or 1 (continuous steps)
• Turning 360° — Steadiness — Scores 0 (unsteady or grabs) or 1 (steady throughout)
• Sitting Down — Scores 0 (unsafe), 1 (uses arms or jerky motion), or 2 (safe and smooth)

Gait Subscale (POMA-G): 8 Items, Maximum 12 Points

Clinicians observe the patient walking approximately 10 feet, turning, and returning to the starting point:

• Initiation of Gait — Scores 0 (hesitancy or multiple attempts) or 1 (initiates without hesitation)
• Step Length & Height — Right Foot — Scores 0 or 1 based on whether the right foot passes the left stance foot and fully clears the floor
• Step Length & Height — Left Foot — Scores 0 or 1 based on whether the left foot passes the right stance foot and fully clears the floor
• Step Symmetry — Scores 0 (unequal step lengths between sides) or 1 (equal steps)
• Step Continuity — Scores 0 (stopping or discontinuous steps) or 1 (continuous fluid steps)
• Path (over approximately 10 feet) — Scores 0 (marked deviation), 1 (mild or moderate deviation, or uses aid), or 2 (straight path without aid)
• Trunk — Scores 0 (marked sway or uses aid), 1 (no sway but knee or back flexion, or uses arms), or 2 (no sway, no flexion, no aid)
• Walking Stance — Scores 0 (heels apart during walking) or 1 (heels almost touching)

Score Interpretation and Fall Risk Stratification

Scores on the Tinetti calculator map to three clinically actionable fall risk categories:

• Score ≤ 18 points — High fall risk: intensive intervention, environmental modification, and close monitoring are indicated
• Score 19–23 points — Moderate fall risk: targeted balance training and strengthening exercises are recommended
• Score ≥ 24 points — Low fall risk: routine monitoring and preventive exercise are appropriate

Research published through Sacred Heart University demonstrated that community-dwelling older adults scoring 18 or below face a fourfold increase in fall risk compared to those scoring above that threshold. The Old Dominion University test-retest reliability study reported intraclass correlation coefficients (ICC) of 0.85–0.90 for both subscales, confirming strong reliability for clinical and research use. Additionally, the FDA NDA review 125513 recognized POMA-B and POMA-G as validated outcome measures in pharmaceutical trial submissions, underscoring the scale's regulatory standing.

Clinical Use Cases

Physical therapists, geriatricians, neurologists, and rehabilitation specialists deploy the POMA across multiple care settings:

• Acute inpatient rehabilitation — Establishes a functional baseline on admission to anchor physical therapy goals and discharge planning
• Outpatient geriatric clinics — Annual or semi-annual screening detects progressive functional decline before a fall event occurs
• Long-term care and skilled nursing facilities — Identifies residents who require individualized fall-prevention programs and assistive device evaluation
• Clinical drug trials — Provides a validated, standardized endpoint for measuring drug effects on mobility in neurodegenerative disease studies

Worked Example

Consider a 79-year-old patient recovering from a right-hemisphere stroke. Balance items score 1+1+1+1+1+1+1+1+0+1 = 9 out of 16 (POMA-B). Gait items score 1+0+0+1+0+1+1+0 = 4 out of 12 (POMA-G). Total POMA = 13, placing the patient in the high fall risk category. The result directs the care team to prioritize intensive balance retraining, gait aid prescription, and home-safety assessment before discharge.
