Understanding the NASM Framework for Fall Risk
The National Academy of Sports Medicine (NASM) recognizes that falls in older adults are a complex issue, influenced by both internal (intrinsic) and external (extrinsic) factors. While intrinsic factors relate to an individual's physical and cognitive health, external factors are found within the environment. For fitness professionals certified through NASM, a comprehensive client assessment includes evaluating these external risks to create a holistic fall prevention strategy.
The most common example of an external factor that influences the risk of falling is the home environment itself. This includes an array of potential hazards that can be modified to significantly reduce risk. Poor lighting, for instance, can obscure obstacles and increase the likelihood of tripping. Clutter, loose rugs, and slippery floors are also major contributors. By addressing these environmental concerns, caregivers and professionals can make a profound impact on an older adult's safety and confidence.
The Critical Role of Environmental Factors
The environment is a powerful determinant of safety, particularly for older adults whose physical capabilities may be declining. A safe environment minimizes the chances of a fall and supports independence. Evaluating a living space for external hazards involves a systematic approach, identifying and mitigating specific risks.
- Lighting: Inadequate lighting, especially in hallways, staircases, and bathrooms, makes it difficult to see hazards. Glare from glossy floors can also be disorienting. Upgrading to brighter bulbs and installing nightlights are simple yet effective solutions.
- Flooring: Uneven, wet, or slippery floors are significant hazards. Loose carpets or area rugs are notorious for causing trips. Using non-slip mats in bathrooms and kitchens and securing rugs with double-sided tape are crucial steps.
- Obstacles and Clutter: A clear path of travel is essential. Furniture placement, electrical cords, and general clutter can all create tripping hazards, especially for those using a cane or walker.
- Assistive Devices: The improper use or maintenance of assistive devices, such as walkers or canes, can increase risk. Ensuring devices are in good working order and fitted correctly is vital.
- Outdoor Conditions: Hazards aren't confined to the indoors. Icy sidewalks, uneven pavement, and poorly maintained steps can pose a serious threat.
Comparing Intrinsic vs. Extrinsic Risk Factors
Recognizing the difference between internal and external risk factors is key to implementing a comprehensive fall prevention plan. While one is about modifying the individual, the other is about modifying their surroundings. The most effective approach addresses both simultaneously.
| Feature | Intrinsic Risk Factors | Extrinsic Risk Factors |
|---|---|---|
| Definition | Relates to an individual's internal physical or psychological state | Relates to environmental and external conditions |
| Examples | Poor vision, reduced muscle strength, balance issues, certain medications | Poor lighting, cluttered pathways, slippery floors, improper footwear |
| Intervention Type | Physical therapy, medication review, balance training | Home modifications, decluttering, installation of safety devices |
| Locus of Control | Largely within the individual's or their healthcare team's control | Found in the immediate environment, often modifiable by the individual or caregiver |
Practical Strategies for Mitigating Environmental Risks
Implementing fall prevention strategies starts with a thorough assessment of the living environment. A NASM-certified professional, or an informed caregiver, can conduct a walk-through to identify potential hazards. The NASM framework encourages a proactive rather than a reactive approach.
- Assess the Home Thoroughly: Conduct a room-by-room review, from entryways to bedrooms. Look for tripping hazards, check stairways, and assess bathroom safety.
- Enhance Lighting: Use motion-activated lights in poorly lit areas. Ensure light switches are easily accessible. Consider high-contrast tape for marking the edges of steps.
- Secure and Declutter: Remove or secure loose rugs. Tape down electrical and phone cords. Keep walkways clear of furniture and other obstacles. Make sure frequently used items are within easy reach.
- Install Safety Equipment: Grab bars in the shower, tub, and near the toilet are essential. Handrails should be installed on both sides of staircases and should be sturdy.
- Address Footwear: Advise older adults to wear supportive, non-slip footwear. Floppy slippers or shoes with slick soles are significant risks.
Why a Combined Approach is Best
While external factors are important, they are often a trigger for a fall that is predicated by intrinsic factors. An older adult with poor balance and muscle weakness is much more likely to fall when they encounter a loose rug. The NASM approach emphasizes a comprehensive, multifactorial intervention. A physical therapist or fitness professional can address the intrinsic issues with targeted exercises to improve balance and strength, while a home safety evaluation tackles the extrinsic problems. This combination provides the most robust protection against falls, promoting a higher quality of life and greater independence.
This holistic strategy aligns with evidence-based practices for healthy aging, ensuring that both the individual and their environment are optimized for safety. By taking control of the variables within the home, older adults and their families can significantly reduce the risk of a life-altering fall.

Conclusion: Proactive Prevention Is Key
The most prominent example of an external factor that influences fall risk is environmental hazards within and around the home. Issues such as poor lighting, unstable flooring, and clutter are major contributors. By systematically assessing and modifying the living space, these risks can be significantly minimized. This environmental approach, combined with addressing intrinsic factors like poor balance and muscle strength, creates a powerful, comprehensive strategy for fall prevention. Empowering older adults with a safer environment and greater physical capability is the ultimate goal, leading to increased confidence and a reduced fear of falling. Through education and proactive interventions, the risk of falls can be managed effectively, ensuring a healthier and more secure aging process.
