Tinetti POMA: Performance-Oriented Mobility Assessment Guide
In short
The Tinetti POMA evaluates both static balance and dynamic gait characteristics; combined scores below 19 indicate a 5-fold increase in catastrophic fall risk.

The Unique Value of the Tinetti POMA: Balance plus Gait Evaluation
Developed by Dr. Mary Tinetti at Yale University in 1986, the Performance-Oriented Mobility Assessment (POMA) is one of the earliest and most extensively validated clinical tools for identifying fall vulnerability in older adults. Unlike tests that examine balance in isolation, the Tinetti POMA explicitly evaluates two interconnected domains: static balance and dynamic walking gait.
The tool provides a thorough 28-point score divided into two subscales: Balance (16 points across 9 maneuvers) and Gait (12 points across 8 observational gait characteristics). By analyzing both domains simultaneously, the clinician can pinpoint whether instability stems from weak transfer mechanics, postural sensory deficits, or abnormal walking kinematics.
Tinetti POMA Subscales and Scoring Breakdown
| POMA Subscale | Specific Tasks Evaluated | Scoring Range | Key Pathological Signs Observed | |
|---|---|---|---|---|
| Balance Subscale (9 Items) | Sitting balance, rising from chair, attempts to rise, immediate standing balance (first 5s), standing balance, sternal nudge perturbation, eyes closed balance, turning 360 degrees, sitting down | 0 to 16 points | Using arms to push off, unsteady initial standing, swaying on sternal nudge, staggering or discontinuous turning, flopping heavily into chair | |
| Gait Subscale (8 Items) | Initiation of gait, step length and height (both feet), step symmetry, step continuity, path deviation (over 3 metres), trunk stability, walking stance width | 0 to 12 points | Hesitation at start, dragging toes/foot drop, asymmetric step lengths, stopping between steps, marked trunk sway or using walking aid, wide-based walking (> 10 cm between heels) | |
| Total POMA Score | Combined Balance + Gait Subscales | 0 to 28 points | < 19 = High Fall Risk; 19-23 = Moderate Fall Risk; 24-28 = Low Fall Risk |
Translating Tinetti POMA Findings into Targeted Interventions
- Deficits in Chair Rise / Descent (Items 2 & 9): Indicates quadriceps and gluteal sarcopenia. Implement eccentric sit-to-stand drills, elevate chair seats, and practice forward trunk lean.
- Deficits on Sternal Nudge (Item 6): The clinician delivers 3 gentle nudges to the patient's sternum. Inability to withstand the nudge indicates blunted ankle/hip righting reflexes requiring perturbation training.
- Deficits in Step Length and Height (Gait Items 2 & 3): Indicates hip flexor weakness or foot drop. Prescribe ankle-foot orthoses (AFOs) and visual floor stepping targets.
- Deficits in Path Deviation and Trunk Sway (Gait Items 6 & 7): Indicates poor core stability and cerebellar coordination. Train walking along straight painted floor lines and prescribe a 4-wheeled rollator.
- Monitoring Treatment Outcomes: Re-administer the Tinetti POMA every 6 to 8 weeks; an increase of 3 to 4 points confirms clinically significant recovery of safe mobility.
Frequently Asked Questions About the Tinetti POMA
What is the difference between the Berg Balance Scale and the Tinetti POMA?
The Berg Balance Scale focuses primarily on static balance and seated/standing transfers. The Tinetti POMA includes an entire 12-point subscale dedicated to evaluating actual walking mechanics (step height, symmetry, continuity, and trunk sway), making it especially valuable for diagnosing walking disorders.
What does a Tinetti score of 17 mean for an elderly parent?
A score of 17 (out of 28) places the patient in the high fall-risk category. Research indicates that seniors scoring below 19 have a five-fold greater risk of experiencing a catastrophic fall compared to those scoring in the normal range. Immediate home physiotherapy and gait aid prescription are indicated.
