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.”
(Feature Impact) When it comes to stroke, time matters. Recognizing the warning signs and calling 911 quickly can help with receiving time-sensitive, life-saving treatment. Recovery should begin early, too.
Having a stroke can divide life into a stark before and after, affecting many aspects of daily life. While it’s easy to focus on the things a stroke can take away, it’s important to remember there’s life after stroke. Recovery isn’t just about relearning skills. It’s about adapting to new challenges, finding purpose in a different reality and continuing to move forward.
Navigating the aftermath of a stroke means balancing short-term and long-term plans. Once medically stable, rehabilitation should ideally begin within 48 hours, according to the 2026 Guideline for Adult Stroke Rehabilitation and Recovery from the American Stroke Association. Recovery doesn’t have a fixed end. Meaningful progress can continue for months or years after survivors leave the hospital or complete formal therapy.
“Stroke rehabilitation is complicated,” said Lorie Gage Richards, Ph.D., FAHA, volunteer chair of the new guideline, associate professor at the University of Utah and an occupational therapist. “Each person faces a different set of challenges and care should be personalized to fit each person’s needs. The goal is to help individuals gain as much independence as possible to perform everyday activities while improving their overall quality of life.”
Approximately 800,000 people have a stroke each year in the U.S, according to the American Heart Association’s 2026 Heart Disease and Stroke Statistics. Whether you’re navigating recovery yourself or supporting someone you love, connecting with a coordinated healthcare team is an important first step. Ask about a comprehensive assessment, develop a rehabilitation plan based on what matters to you and set small, achievable goals throughout recovery.
Building Skills and Independence
After a stroke, familiar parts of a daily routine may take more effort or require a new approach. A rehabilitation team can assess how stroke has affected movement, communication, thinking, vision, hearing and other abilities then develop a plan based on individual needs and goals.
Recovery doesn’t look the same for everyone. For one person, a meaningful goal may be dressing independently. For others, it could be returning to work, driving safely or participating in favorite activities. Start with manageable goals, evaluate progress and reassess the plan as needs change.
Understanding the Invisible Impacts
Some of the most challenging parts of recovery may be the ones others can’t see. For instance, you might lose confidence or sense of identity, have trouble concentrating or experience anxiety or depression. Along with mental and emotional changes, you may notice ongoing physical symptoms like pain, difficulty sleeping, changes in sexual function or difficulty with bladder control.
Invisible challenges don’t have to stay that way. Ask your healthcare team to assess your physical and emotional health, including depression and anxiety, during the hospital stay and throughout recovery. Speaking up about new or changing symptoms can help identify appropriate treatment and support.
Navigating Changing Relationships
When you have a stroke, your life isn’t the only one that changes. A partner, parent or friend may suddenly take on new responsibilities, making honest conversations about support especially important.
Family responsibilities may also look different. Parenting young children, supporting loved ones or balancing work and family can bring new challenges during recovery. Give yourself permission to slow down, accept care and connect with the people who matter most.
Finding Purpose and Redefining Success
Recreation, hobbies, social connections and other meaningful activities are an important part of recovery and can help people regain confidence, participate in their communities and improve quality of life. That may mean returning to music, art, exercise or time with friends. It could also mean modifying favorite activities, discovering new interests or connecting with a support group.
Life after stroke may look different, but different doesn’t mean less meaningful. Recovery isn’t measured by how closely someone returns to who they were before. It’s about finding new ways to pursue what matters most and continuing to move forward.

Design Your Home Workout Space Around the Way You Actually Exercise
Use these tips to create a home workout space you’ll keep using after the novelty wears off.
Design Your Home Workout Space Around the Way You Actually Exercise
(Feature Impact) It’s a tale as old as treadmills: You buy a new exercise machine with the best of intentions, only for it to become an expensive laundry rack that makes you feel guilty every time you glance over at it. When it comes to making lifestyle changes, the key is not to overhaul your whole routine at once, but to figure out what habits match your lifestyle, personality and passions.
Use these tips to create a home workout space you’ll keep using after the novelty wears off.
Figure Out What Exercises You Enjoy
Before you commit to a big equipment purchase, think about what kinds of exercise feel natural and enjoyable (and which ones make you groan).
If you love running, a treadmill may be worth the space it takes up. However, a rack of dumbbells might just wind up collecting dust if you hate lifting weights. Yoga or dance enthusiasts may prefer to design a more studio-like home gym, while bodyweight strength trainers could be happy with a pull-up bar in the doorway and a mat to do planks on. Consider joining a workout class or gym for a month or two to try different kinds of exercises and machines so you’ll have a better idea of what’s worth investing in permanently.
Evaluate the Space You Have
A good home workout area needs to work around the physical realities of your house or apartment. If you have a whole room or finished basement to dedicate to the cause, this won’t constrain you too much. If you’re working with a corner of your home office, bedroom or garage, saving space becomes a more critical factor.
In these cases, it all comes down to priorities. If you only have room for one piece of bigger equipment, get the one you know you’ll actually use, whether that’s an elliptical, strength machine, standing bicycle or rowing machine. Then build out your collection with other items that can be easily moved and stored, like resistance bands and small weights or dumbbells.
Start Small and Expand as Needed
Don’t fall into the trap of thinking you need to have everything before you can get started. It’s often better to build out your workout space slowly – get a few things at a time, see what you use regularly and figure out what you might be missing along the way. Maybe you realize you enjoy lifting weights and keep wishing you had heavier ones, signaling a need to upgrade.
Add Some Atmosphere
Dark, dismal home gyms are more likely to make your workout feel like a punishment instead of a part of your day worth looking forward to. Creating a space you enjoy being in is just as important as choosing a workout you enjoy doing.
For you, that might look like choosing an area of the home with plenty of natural lighting to make you feel more awake – or adding string lights and color-changing wall sconces for a relaxing yoga session. Maybe it means adding art on the walls or a floor-to-ceiling mirror so you can check your form. A large rubber floormat with a cheerful design, a sound system to play your favorite hype songs or a daily calendar of motivational quotes could be the magic ingredient to get you into the right mindset so you can crush your workout. As long as it works for you, anything goes.

4 Daily Brain Health Habits for Better Cognition
(Feature Impact) Your brain works hard for you, so it’s only fair to return the favor by practicing simple everyday habits to keep this important organ strong and thriving.
Start by tweaking your daily routine to focus on these four habits.
Prioritize Sleep
Getting quality sleep is vital for proper brain function. If you find you’ve slipped into the habit of staying up later than you should or notice your sleep being disrupted during the night, those are signs to revisit your sleep hygiene practices. Start by establishing a regular bedtime and wake-up time that will give you the recommended 7-9 hours of sleep. Turn your bedroom into a comfortable refuge from the world – keep it cool and dark, and set up fans or noise machines if you need them to quiet your mind. Avoid consuming caffeine or alcohol too close to bedtime and try switching to a book instead of a screen when it’s time to wind down.
Eat Smart
Just like the rest of the body, the brain is nourished by food. Some of its favorite foods are options rich in healthy fats like fish, avocado, olive oil and nuts, as well as vegetables like leafy greens, which offer carotenoids, and fruits such as grapes, which deliver antioxidants and other polyphenols.
Combine several of these powerful brain-boosting foods at once with this California Grape and Sardine Avocado Toast recipe. The fish is rich in omega-3 fatty acids and the avocado offers a boost of healthy unsaturated fat, while the grapes add protective dietary flavonols, which may help promote anti-inflammatory and beneficial antioxidant activity.
A study published in the scientific journal “Neurology” found a higher intake of certain flavonols – including three naturally found in grapes – is associated with a 48% decreased risk of developing Alzheimer dementia.
Get Moving
Adding even more proof that what’s good for your body is good for your mind, getting regular exercise is one of the best things you can do for your brain. Motivate yourself by choosing a form of movement you genuinely enjoy, whether it’s a daily walk on a nearby nature trail, a dance class, a bike ride or a heart-pumping workout video.
Challenge Your Mind
Don’t forget to give your brain its own workout, too. Doing something mentally stimulating every day is a great way to keep yourself sharp, and there are plenty of ideas to choose from. Try learning a new language, picking up a musical instrument, playing a mind-engaging card or board game, doing a puzzle, reading a book or immersing yourself in a creative writing or art project. The options are nearly endless, and if you want to make your brain extra happy, you can snack on handfuls of grapes as you enjoy your hobby.
