Falls in Elderly
• Common feature of frailty
• Increased morbidity
• Restricted mobility
• Increased risk of nursing home placement

Predictors of Fall Risk
• Intrinsic Factors
– Advanced age
– Sensory deficits
– Musculoskeletal Disorders
– Neurologic Disorders

Predictors of Fall Risk
• Environmental Factors
– Use of multiple medications
– Cluttered hallways
– Slippery floors

Physical Performance Measures
• Lower extremity weakness
• Gait assessment
• Balance
![Page 6: Physical Function and Fall Risk among Urban Community Dwelling Elders Arline Bohannon, MD Pamela Parsons, PhD Department of Internal Medicine Section of](https://reader035.vdocument.in/reader035/viewer/2022072015/56649eb65503460f94bc0543/html5/thumbnails/6.jpg)
Objectives
• To describe physical function and fall risk among community dwelling minority elders
• To evaluate the relationships between self-reported physical function and physical performance among minority elders

Study Design
• Cross sectional
• Study sample – 50 volunteersExclusion criteria:
Unable to understand English
Moderate-severe cognitive impairment
![Page 8: Physical Function and Fall Risk among Urban Community Dwelling Elders Arline Bohannon, MD Pamela Parsons, PhD Department of Internal Medicine Section of](https://reader035.vdocument.in/reader035/viewer/2022072015/56649eb65503460f94bc0543/html5/thumbnails/8.jpg)
Short Portable Mental Status Questionnaire
• Cognitive Function
– 10 item survey
– 5 or more errors = cognitive impairment

Late Life Function and Disability Instrument (LLFDI)
• Self report physical function instrument
• Administered by trained reviewer
• 48 item questionnaire– Disability component (16 items)– Functional component (32 items)

Modified Timed Get Up and Go
• Measures physical mobility
• Measured in seconds
• Test– Stand from a standard armchair– Walk three meters– Turn 180°– Walk back to chair – Sit down

Tinetti Assessment Tool
• Measures gait and balance
• Balance test– 14 maneuvers– Scored on a three point ordinal scale– Range from 0 to 2 for each task– Maximum score is 16
![Page 15: Physical Function and Fall Risk among Urban Community Dwelling Elders Arline Bohannon, MD Pamela Parsons, PhD Department of Internal Medicine Section of](https://reader035.vdocument.in/reader035/viewer/2022072015/56649eb65503460f94bc0543/html5/thumbnails/15.jpg)
Tinetti Assessment Tool
• Gait test– 10 components– Ranges form 0 to 16– Maximum score = 12
• Total score– Balance + Gait– Maximum score = 28– Higher functioning = better mobility
![Page 16: Physical Function and Fall Risk among Urban Community Dwelling Elders Arline Bohannon, MD Pamela Parsons, PhD Department of Internal Medicine Section of](https://reader035.vdocument.in/reader035/viewer/2022072015/56649eb65503460f94bc0543/html5/thumbnails/16.jpg)
Tinetti Assessment Tool
• Low Risk– Total score > 24
• Moderate Risk– Total score 19-24
• High Risk– Total score < 19
