What is the appropriate physical assessment to evaluate fall risk in a 74‑year‑old female?

Fall Risk Physical Assessment in a 74-Year-Old Female

Begin with the three key screening questions, and if any answer is "yes," proceed immediately to functional testing with the Timed Up and Go (TUG) test or 4-Stage Balance Test to quantify fall risk. 1

Initial Screening Approach

Start your assessment by asking these three validated screening questions 1:

• Have you fallen in the past year?
• Do you feel unsteady when standing or walking?
• Are you worried about falling?

A "yes" answer to any single question constitutes a positive screen and mandates further evaluation. 1 This approach has been validated specifically in community-dwelling older adults and forms the foundation of the CDC's STEADI program. 2

Functional Performance Testing

When screening is positive, immediately perform objective functional tests. The 2024 Mayo Clinic guidelines provide clear cutoffs 1:

Timed Up and Go (TUG) Test

• Instruct the patient to rise from a chair, walk 3 meters, turn around, walk back, and sit down 1
• A time >12 seconds indicates increased fall risk 1, 3
• This test has strong evidence support and is the most validated functional measure for predicting future falls 3

4-Stage Balance Test

• Have the patient stand in four progressively challenging positions for 10 seconds each: feet side by side, semitandem stand, tandem stand, and single-foot stand 1
• Inability to hold tandem stand for 10 seconds indicates increased fall risk 1
• This test directly assesses balance impairment, which is one of the most common fall risk factors 2

Alternative: 30-Second Chair Stand Test

• Count how many times the patient can rise from a chair in 30 seconds 2
• This assesses lower extremity strength, a critical physiological factor associated with falls 4

Comprehensive Risk Factor Assessment (P-SCHEME)

If functional testing is abnormal, evaluate these specific modifiable risk factors using the P-SCHEME mnemonic 1:

• Pain: Assess for axial or lower extremity pain 1
• Shoes: Examine footwear characteristics for safety 1
• Cognitive impairment: Screen with Mini-Cog or similar tool 1
• Hypotension: Check for orthostatic hypotension (measure blood pressure supine and after 1-3 minutes standing) 1
• Eyesight: Evaluate visual acuity and contrast sensitivity 1, 4
• Medications: Review for centrally acting drugs and polypharmacy (≥5 medications) 1
• Environmental factors: Assess home safety hazards 1

Additional Physical Examination Components

Beyond functional tests, assess these physiological factors that strongly predict falls 4:

• Visual contrast sensitivity: Low contrast visual acuity is significantly associated with multiple falls 4
• Proprioception and vibration sense: Test lower limb position sense and vibration perception 4
• Quadriceps strength: Reduced lower limb strength discriminates between fallers and non-fallers 4
• Gait observation: Watch for any gait abnormalities or use of assistive devices 1

Alternative Comprehensive Tools

For a more structured multidomain assessment, consider the Stay Independent questionnaire, which evaluates fall history, balance, gait aid use, medications, and specific symptoms 1. A score ≥4 (out of 12) indicates increased fall risk. 1

Critical Action Thresholds

Any of the following findings mandate broader fall risk assessment and intervention 1:

• Observed gait abnormalities
• Use of a gait aid
• Positive answer to any of the 3 key questions
• TUG score >12 seconds
• Inability to hold tandem stand for 10 seconds

Common Pitfalls to Avoid

The patient's history may be inaccurate if cognitive impairment is present, so objective functional testing is essential rather than relying solely on self-report 2. Additionally, physical examination can yield false-negative findings, particularly for subtle balance deficits, which is why standardized functional tests with validated cutoffs are superior to informal assessment 2.

When any screening or functional test is positive, refer to physical therapy for exercise program development and evaluation for walking aids. 1 Exercise interventions that improve balance and strength (tai chi, walking, resistance training) are proven to reduce fall risk and maintain mobility. 1
