You hurt your knee. You develop back pain. You have shoulder problems. You undergo surgery. You lose your balance. Then you see a physical therapist. But physical therapy can play another important role—helping you maintain physical function as you age. You don’t necessarily have to wait until something hurts to have your body evaluated. At PhysioFit of NC in Wake Forest, NC, we take a proactive approach to physical therapy for healthy aging. Our goal is to help you maintain the physical abilities that allow you to stay active, independent, and engaged in the activities you enjoy. Because healthy aging isn’t simply about how long you live. It’s also about how well you move throughout those years. What Is Healthy Aging? Healthy aging is often associated with avoiding disease or living as long as possible. But there’s another important component: maintaining function. The World Health Organization describes healthy aging as the process of developing and maintaining the functional ability that enables well-being in older age. Functional ability includes your ability to move, meet your basic needs, maintain relationships, and participate in activities that are meaningful to you. That means healthy aging isn’t just about a number on your birthday cake. It’s about whether you can continue doing the things that make your life enjoyable. Can you walk? Can you climb stairs? Can you get up from the floor? Can you carry your groceries? Can you travel? Can you exercise? Can you garden? Can you play with your grandchildren? Can you maintain your independence? Physical function matters. Why Physical Therapy Can Be Part of Healthy Aging Your body changes throughout your lifetime. Strength can change. Balance can change. Mobility can change. Muscle activation can change. Endurance can change. Movement patterns can change. Sometimes these changes happen gradually enough that you don’t notice them. You may simply find that something that used to feel easy requires more effort. Maybe you have more difficulty getting up from a chair. Maybe you don’t feel as steady on one leg. Maybe you can’t walk as far without becoming tired. Maybe you have stopped doing certain activities because they don’t feel as comfortable as they used to. These changes don’t necessarily mean that something is wrong. But they can provide valuable information. Physical therapy can help you understand why these changes are occurring and what you can do about them. You Don’t Have to Wait Until You Have Pain Traditional physical therapy is often reactive. Something hurts, so you seek treatment. A proactive approach asks a different question: “How is my body performing before I have a problem?” You can have reduced strength without pain. You can have poor balance without having fallen. You can have decreased mobility without having an injury. You can have muscle weakness or poor activation without realizing it. This is why preventive physical therapy can be valuable. Rather than waiting for a problem to interfere with your life, you can periodically evaluate your physical performance and identify areas that may benefit from attention. What Should You Maintain as You Age? There isn’t one exercise that has been established as the single “best” exercise for healthy aging. Research supports a combination of physical activity, including aerobic exercise, muscle strengthening, and activities that challenge balance and functional ability. The World Health Organization recommends that older adults participate in regular physical activity that includes these different components. The important question isn’t necessarily: “What is the best exercise?” A better question is: “What does my body need?” For one person, the answer may be strength. For another, balance. For another, mobility. Someone else may need to improve muscular endurance or movement control. Your exercise program should reflect your individual needs and goals. Five Physical Abilities That Support Healthy Aging At PhysioFit of NC, we focus on five important physical abilities that can help you remain active and independent: Strength Strength helps you stand from a chair, climb stairs, carry objects, get up from the floor, and participate in exercise and recreational activities. Balance Balance allows you to control your body while standing and moving, particularly when walking, changing direction, navigating uneven surfaces, or responding to unexpected changes. Mobility Mobility allows you to move your joints and body through the ranges of motion needed for everyday activities. Stability and Control Strength isn’t enough. Your body also needs to control movement. Stability allows you to use your strength efficiently while maintaining appropriate alignment and control. Endurance Endurance allows you to continue performing physical activities without becoming excessively fatigued. These abilities work together. Walking, for example, requires strength, mobility, balance, stability, coordination, and endurance. Introducing the 6 Green Zones™ One of the unique aspects of our approach to healthy aging is the 6 Green Zones™. The 6 Green Zones™ are six regions of the body that we evaluate as part of our approach to physical performance: Shoulders Neck Thoracic Spine Lumbar Spine Hips Calves Within these regions, we look at specific muscles and their ability to contribute to strength, stability, symmetry, muscle activation, and movement control. The 6 Green Zones™ are not intended to suggest that these are the only areas of the body that matter. Instead, they provide a practical framework for evaluating areas that, in our clinical experience, commonly become involved in musculoskeletal problems, weakness, compensation, or loss of function over time. Why Focus on These Areas? After more than 20 years of treating orthopedic and musculoskeletal conditions, physical therapists see patterns. Certain regions of the body repeatedly become areas of concern. The shoulders can develop rotator cuff problems. The neck and spine can develop degenerative changes and movement limitations. The lumbar region can become a source of pain and reduced stability. The hips can develop weakness, asymmetry, and degenerative changes. The calves can lose strength and endurance. This doesn’t mean that everyone will develop a problem in these areas. And it doesn’t mean these are the only areas that matter. Instead, the 6 Green Zones™ represent areas we believe are worth proactively evaluating and optimizing because of their importance to movement and physical function. The goal isn’t to prevent aging. The goal is to optimize how your body functions as you age. The Shoulders: Maintaining Upper-Body Function Your shoulders allow you to reach, lift, push, pull, carry, and exercise. Within the 6 Green Zones™, we pay particular attention to the rotator cuff and supraspinatus. Maintaining appropriate shoulder activation and stability can help support the upper-body function you need for everyday activities. The Neck: Supporting Head Stability and Control Your neck plays an important role in head stability, posture, movement, and the interaction between your visual and sensory systems. The cervical multifidi are small stabilizing muscles that contribute to cervical control. Maintaining appropriate cervical function can be particularly relevant to overall movement and balance as we age. The Thoracic Spine: Supporting Upper-Body Movement The thoracic spine connects the neck, shoulders, ribs, and lower back. Its mobility and stability contribute to posture, rotation, and upper-body movement. The thoracic multifidi contribute to spinal stability and control. Optimizing this region can help support efficient movement throughout the upper body. The Lumbar Spine: Supporting Low-Back Stability The lumbar spine provides a foundation for the trunk and helps transfer forces between the upper and lower body. The lumbar multifidi contribute to segmental spinal stability. Research in older adults provides evidence that targeted trunk strengthening and motor-control exercises can improve lumbar multifidus size, trunk strength, and several measures of physical function. In one randomized controlled trial involving adults aged 60 and older, participants who performed additional trunk strengthening and motor-control exercises demonstrated improvements in lumbar multifidus size, trunk strength, and functional measures. This doesn’t mean everyone needs to specifically train their multifidi. It does demonstrate the potential value of targeted exercise based on individual physical needs. The Hips: Supporting Balance and Lower-Body Control Your hips are central to walking, climbing stairs, standing on one leg, and controlling your lower extremities. The gluteus medius and gluteus minimus contribute to pelvic stability and lower-body control. Maintaining hip strength and control can be particularly important for balance and efficient movement. Within the 6 Green Zones™, we evaluate these muscles for their ability to activate and contribute appropriately during movement. The Calves: An Often-Overlooked Component of Healthy Aging Your calves play a critical role in walking and standing. The soleus, in particular, is an important postural muscle that is active during standing and walking. Calf strength and endurance contribute to propulsion, balance, and lower-extremity function. Yet the calves are often overlooked in conversations about healthy aging. That’s one reason they are included as one of the 6 Green Zones™. Optimizing the Body Before Problems Become Limitations The 6 Green Zones™ aren’t designed to predict exactly where you will develop pain. They aren’t designed to diagnose future disease. And they aren’t a replacement for comprehensive medical care or a complete exercise program. Instead, they provide a framework for asking: Are these important areas of my body functioning as well as they could? If an area demonstrates reduced activation, asymmetry, weakness, or poor control, it gives us an opportunity to address it. The goal is to optimize function—not simply react to dysfunction. What Is PhysioFit Age®? This proactive approach also led to the development of PhysioFit Age®. Your chronological age tells you how many years you’ve been alive. It doesn’t necessarily tell you how your body performs. PhysioFit Age® provides a snapshot of physical performance relative to chronological age. It combines information from the 6 Green Zones™ with additional physical performance measures to provide a way to look at your current physical function. PhysioFit Age® is not intended to predict lifespan or serve as a medical measure of longevity. Instead, it provides a physical performance snapshot. And because physical performance can change, you can reassess over time. Who Should Consider Physical Therapy for Healthy Aging? You don’t need to be injured to benefit from a proactive physical therapy assessment. It may be appropriate if you: Want to stay active as you age Want to maintain strength and mobility Are concerned about losing balance Want to maintain your independence Have noticed changes in your physical abilities Want to continue exercising safely Are returning to exercise after time away Want to identify areas of weakness before they become problems Are interested in tracking your physical performance over time The goal is to meet you where you are today and determine what your body needs next. A Different Way to Think About Physical Therapy Physical therapy doesn’t have to begin when something goes wrong. It can begin with curiosity. How is my body performing? Where am I strong? Where could I improve? Are there areas I should be paying more attention to? What can I do today that may help me maintain my physical abilities tomorrow? That’s the philosophy behind preventive physical therapy and our longevity approach at PhysioFit of NC. Physical Therapy for Healthy Aging in Wake Forest, NC At PhysioFit of NC, we believe healthy aging is about maintaining your ability to move, participate, and remain independent.
