Faster knee for better walking
Scientists find knee extension velocity while seated strongly predicts walking performance in elderly patients after total knee arthroplasty
Scientists measured gait function, knee extension velocity while seated, quadriceps strength, knee range of motion, and knee pain in 186 total knee arthroplasty patients to identify the most important determinant of postoperative gait function.
« Faster knee for better walking
Newswise — Osaka, Japan – “Speed or strength, which is more important?” may be a critical question for not only athletes but also knee surgery patients. Osaka Metropolitan University scientists have revealed that knee extension velocity while seated is a stronger predictor of walking performance than muscle strength in elderly patients after their total knee arthroplasty (TKA) surgery.
TKA is the most common surgical intervention for knee osteoarthritis, a musculoskeletal disorder that mainly progresses with age. This surgery has been shown to be effective in relieving pain and restoring joint range of motion; however, TKA-enabled improvement in gait function may not be sufficient. Although the strength of the quadriceps—a muscle used to extend the knee—has been deemed to have a significant effect on postoperative gait function in TKA patients, there are many cases in which gait function does not improve even after quadriceps strength is restored. This raises a need to identify other factors influencing gait function.
A research team led by Professor Akira Iwata, from the Graduate School of Rehabilitation Science at Osaka Metropolitan University, hypothesized that the movement velocity of knee extension (i.e., knee extension velocity) is a strong determinant of gait function in TKA patients, and tested this hypothesis on 186 elderly patients who underwent TKA. Measurements were taken before and at 2 and 3 weeks after surgery and included gait function (gait speed and Timed Up and Go test), knee extension velocity, quadriceps strength, knee range of motion, and knee pain. Multiple regression analysis was performed to analyze the relationship between gait function and other variables.
The results show that the knee extension velocity on the operated side was the most important predictor of gait function in the participating patients. The findings were published in PLOS ONE.
“Thus far, rehabilitation programs aimed at recovering gait function after TKA surgery have focused on training to improve quadriceps strength,” explained Professor Iwata. “However, this study’s results suggest that training to enhance knee extension velocity on the operated side could be effective. We will continue to examine the effects of rehabilitation that concentrates on movement velocity.”

Stopping the ‘Silent Killer:’ How to Check, Prevent and Manage High Blood Pressure
Stopping the Silent Killer: High blood pressure poses significant health risks for people of all ages, but there are effective ways to both prevent and manage this “silent killer” by working with a health care professional to make lifestyle changes.
Stopping the ‘Silent Killer:’ How to Check, Prevent and Manage High Blood Pressure
(Feature Impact) High blood pressure poses significant health risks for people of all ages, but there are effective ways to both prevent and manage this “silent killer” by working with a health care professional to make lifestyle changes.
Hypertension, also known as high blood pressure, is when the force of blood flowing through blood vessels is consistently too high. This condition makes the heart work harder than normal and can damage arteries, increasing the risk of heart disease, stroke and other health problems.
High blood pressure is the leading risk factor for stroke and heart conditions such as coronary artery disease, heart failure and atrial fibrillation. Strengthening evidence also shows high blood pressure is linked to risk of cognitive decline and dementia, which is why the American Heart Association is working to increase awareness and encourage people to manage blood pressure. Protect your heart and brain both now and in the future with this information and wellness advice.
Who Can Have High Blood Pressure?
Anyone can develop high blood pressure, which is why it’s encouraged for everyone – in all age groups, including children and young adults – to have their blood pressure checked at annual physicals or wellness checkups. For those with a history of high blood pressure or risk factors for developing the condition, more frequent measurements may be recommended.
Major risk factors for high blood pressure include excess weight, diabetes, high cholesterol, smoking, lack of physical activity, alcohol consumption and a diet high in sodium and low in potassium.
Nearly half of adults in the U.S. have high blood pressure and many don’t even know it. Of those with high blood pressure, about 75% don’t have the condition under control. Because it typically shows no symptoms, it’s often called a “silent killer.”
How is Blood Pressure Checked?
To get the best blood pressure reading, sit in a chair with support for your back with both feet flat on the ground.
Use a validated, automatic, cuff-style, upper-arm monitor. Remove clothing over the arm that will be used and rest for at least 5 minutes. Extend your arm and support it at heart level while staying quiet and still then take multiple readings and record the results. Aim to measure at the same time each day.
For most adults, a normal blood pressure reading should be less than 120/80 mm Hg.
What Happens After a High Blood Pressure Diagnosis?
Recognizing and taking quick action to control high blood pressure can significantly lower the risk of severe health consequences, including heart attack and stroke, and improve overall health. If you’ve been diagnosed with high blood pressure, work with a health care professional to design a treatment plan that works for you. It may include lifestyle changes to your diet or activity levels or medication.
How Can High Blood Pressure Be Prevented or Managed?
Preventing high blood pressure is possible. Talk with a health care professional to create a plan that works for you, which may include small steps like eating a heart-healthy diet, staying active and maintaining a healthy weight.
For those diagnosed with high blood pressure, maintaining a healthy weight by staying active (at least 150 minutes of moderate activity per week) and eating a balanced diet rich in fruits, vegetables, lean protein and whole grains are important. Even losing 5% of your weight can help improve blood pressure.
It’s also important to reduce or avoid alcohol consumption and tobacco use. Consider stress-reducing activities, including meditation, breathing control or yoga. For many individuals, adhering to prescribed medications is essential to effectively control blood pressure and reduce the risk of serious health complications.

Stacking Healthy Habits for Progress, Not Perfection
Healthy Habits: Many struggle with building healthier habits due to unrealistic expectations rather than lack of motivation. The American Heart Association’s My Life Check tool offers personalized heart health insights, helping to set attainable goals. Simple lifestyle changes—focused on nutrition, movement, sleep, and stress management—can gradually lead to significant health improvements.

(Feature Impact) Despite the best of intentions, it’s common for plans to build healthier habits to fall flat. Often, the culprit isn’t a lack of motivation or discipline; rather, it’s unrealistic expectations.
Overhauling your lifestyle requires a level of commitment that isn’t always practical. Understanding your personal health needs and the challenges you need to overcome can help give you a more realistic roadmap toward better health.
Tools to Guide You
Every plan needs a starting point and there are many reputable sources that can help guide you toward a plan that addresses your personal health needs.
For example, the American Heart Association introduced My Life Check, a simple, free tool to help individuals understand their heart health and what’s driving it. Users answer simple questions about their daily habits and health factors to get a personalized Heart Health Score in minutes.
The results are private and downloadable, giving you full control of your information. The tool turns big goals into small, specific actions you can start right away. Knowing your numbers relative to your heart health (and where you are in comparison to target ranges for optimal health) can help you decide how to build a better map to get you where you want to be.
While the report is customized to each individual, no personal data is stored and answers are only used to calculate health scores and provide personalized recommendations and practical steps to improve your health, so you can use your results to focus on what matters most to you. Every small step you take, such as moving more, eating smarter, sleeping better or managing stress, can add up over time.
Finding Your Path
Once you’re armed with data and know where you stand on your heart health numbers, small steps become clearer and more manageable. That knowledge makes it easier to choose one area to focus on, such as getting more sleep, taking daily walks or adding more color to your meals.
Healthy changes don’t need to be expensive or complicated. The best habits are ones that fit real life when every action you take moves you closer to your goals.
Eat Smart
Choose foods that help you feel your best, one meal at a time. Add more color to your plate and focus on balance, not restriction. Simple, affordable swaps can make a real difference.
Move More
Find movement that fits your life, such as a walk, a stretch or dancing while you cook. Every bit of activity counts and it all supports your heart and mind. Move for joy, not just for results.
Sleep Well
Rest is a foundation of good health, not a reward. Protect your bedtime routine and give your body the recovery it deserves. Notice how good sleep makes everything else easier.
Manage Stress
Check in with yourself regularly, both mentally and emotionally. Create simple moments to pause, breathe, laugh or step outside. Connection, kindness and calm all support a healthy heart.
Staying motivated and on track is also easier when you can check back in, see your progress and realize the steps you’re taking are making an impact. Checking in every few months to see how you can grow gives you the chance to celebrate your progress, learn from challenges and keep building lasting habits that feel good.

Healthy Habits for Everyday Life
Eat Smart
Choose foods that help you feel your best, one meal at a time. Add more color to your plate and focus on balance, not restriction. Simple, affordable swaps can make a real difference.
Smart Tip: Aim for an overall healthy eating pattern that includes whole foods, fruits and vegetables, lean protein, nuts, seeds and cooking in non-tropical oils such as olive and canola.
Move More
Find movement that fits your life, such as a walk, a stretch or dancing while you cook. Every bit of activity counts and it all supports your heart and mind. Move for joy, not just for results.
Smart Tip:Adults should get 150 minutes of moderate physical activity (or 75 minutes of vigorous activity) per week. Kids should aim for 60 minutes every day, including play and structured activities.
Sleep Well
Rest is a foundation of good health, not a reward. Protect your bedtime routine and give your body the recovery it deserves. Notice how good sleep makes everything else easier.
Smart Tip: Most adults need 7-9 hours of sleep each night. Children require more. Adequate sleep promotes healing, improves brain function and reduces the risk for chronic diseases.
Manage Stress
Check in with yourself regularly, both mentally and emotionally. Create simple moments to pause, breathe, laugh or step outside. Connection, kindness and calm all support a healthy heart.
Smart Tip:The first step to stress management is awareness. Step “away from yourself” for a moment. Objectively ask yourself, “Is my stress level too high?” If so, look at what might be causing that stress.
Ideas for Incremental Changes
- Dedicate 15 minutes at the beginning or end of the day to focus on self-care, whether it’s unwinding with some music, writing down your goals or reflecting on the highlights of the day.
- Aim to add an extra serving of fruits or veggies each day, such as creating a savory veggie omelet or exploring new smoothie blends that let you pack in the produce on the go.
- Give your cabinets a quick update and put the smaller plates front and center. When you use a smaller plate, you can fill it while still sticking to recommended serving sizes.
- If you’re not a fan of the gym, think about how your hobbies can play a role in your physical activity. Even gardening counts as physical activity, so get creative to get moving with an activity you truly enjoy.
- Establish a bedtime routine that allows you to ease into sleep more easily. Once you feel the impact of better-quality rest, you may find yourself more motivated to make a regular bedtime a priority.
