One of the most prevalent and crippling signs of Parkinson's disease, which is a neurological condition that affects over 9 million individuals globally, is freezing. A person with Parkinson's disease freezes; their feet frequently stop moving in mid-stride, causing them to staccato stutter and take shorter and shorter steps until they stop completely. These falls are one of the main causes of falls in Parkinson's disease patients.
Currently, a variety of pharmaceutical, surgical, and behavioral interventions are used to treat freezing, but none of them are very successful.
The patient may walk with a longer stride thanks to the robotic garment, which is placed around the thighs and hips and gently presses the hips when the leg swings, helping the patient to achieve a longer stride.
The wearer was able to walk faster and farther than they could have without the assistance of the garment because the technology totally removed their freezing while they were indoors.
Conor Walsh, the Paul A. Maeder Professor of Engineering and Applied Sciences at SEAS and co-corresponding author of thestudy,y stated that it was found that the small amount of mechanical assistance from the wearable robot made an intermediate effect and consistently helped improve walking across a range of conditions for the individual.
The research showed the potential of soft robotics used to treat the dangrous symptoms of Parkinson disease, giving people the ability to regain both their mobility and independence.
The Wyss Institute for Biologically Inspired Engineering supported some of those technologies, including an exosuit for post-stroke gait retraining, and Harvard's Office of Technology Development arranged a license arrangement with ReWalk Robotics to commercialize the technology.
SEAS and Sargent College received a grant from the Massachusetts Technology Collaborative to support the development and translation of next-generation robotics and wearable technologies in 2022. The Move Lab's goal is to support advancements in human performance and enhance them by providing the R&D infrastructure, funding, collaborative space, and experience needed to transform promising research into mature technologies that can be translated through industry partnerships, which serves as the focal point for the research.
Three months were spent by the team working with a 73-year-old man who had Parkinson’s disease and had significant and incapacitating freezing episodes more than ten times a day. Despite using both surgical and pharmaceutical treatments, he still had frequent falls, making him rely on a scooter to move around and prevent him from walking around his community.
In previous research, Walsh and his team made use of human-in-the-loop optimization to demonstrate that a soft, wearable device can be used to augment hip flexion and assist in swinging the leg forward to provide an efficient approach to reducing energy expenditure during walking in healthy individuals.
The researchers addressed freezing using the same approach. It is worn around the waist and thighs, and it is powered by actuators and sensors. With the motion data collected by the sensor, algorithms determine the phase of gait and produce assistive forces in sync with the muscle contraction.
The result was immediate. The patient was able to walk without freezing indoors and with just sporadic episodes outdoors without the need for any extra training. Without the gadget, he was also able to walk and talk without freezing, which was unusual.
The team was quite thrilled to observe how the technology affected the subjects' gait," stated Jinsoo Kim, a co-lead author of the study and a former Ph.D. candidate at SEAS.
Ellis went on to say, "We don't really know why this approach works so well because we don't really understand freezing." This study, however, points out the potential benefits of approaching gait freezing from the "bottom-up" rather than the "top-down" perspective. The recovery to nearly normal biomechanics alters the peripheral gait dynamics and may influence the processing of central gait control.

What if there was a method to completely avoid freezing?
To assist people with Parkinson's disease in walking without freezing, researchers from Boston University Sargent College of Health & Rehabilitation Sciences and Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) used a soft, wearable robot that is placed around the tightened hips to gently press the hips when the leg swings.The patient may walk with a longer stride thanks to the robotic garment, which is placed around the thighs and hips and gently presses the hips when the leg swings, helping the patient to achieve a longer stride.

This is a new report from the World Health Organization.
It points directly while also discussing how to break the cycle of intergenerational adversity using a public health approach from Cambridge Public Health’s recent showcase.
Connecting Generations: Planning and Implementing Interventions for Intergenerational Contact builds on the evidence of 2021’s Global Report on Ageism in its conviction to show ageism the door.
Ageism has long involved thinking, feeling, and acting based on stereotypes, prejudice, and discrimination toward people based on their age. The report points out that ageism is widespread, subtle, often unnoticed, unchecked, and sometimes loud. It also uncovered the significant effect it has on people's health throughout their lives.
These effects also extend to the younger generation as well, because ageism is more common in healthcare, housing associations, and employment and has been frequently linked to mental health decline.
since ageism is more common in the fields of employment, health, and housing and is frequently linked to worse physical and mental health, increased social isolation, and loneliness in older adults. The effect of ageism is even worse when it coexists with racism, sexism, or ableism.
The report is a good resource for public health researchers because it outlines a systematic approach for planning, preparing, and evaluating intergenerational projects. It provides a step-by-step guide but also shows the potential for additional benefits through fostering meaningful relationships across different age groups.
This aligns well with the efforts of CPH's Life-Course and Aging team and their ongoing social return on investment project within age-friendly communities.
The interventions that are suggested create intergenerational programs that lead to long-lasting, community-driven intergenerational contact, and they are affordable and simple to put into practice. Its branch, which offers instructions on organizing and facilitating 40 intergenerational activities that have been proven effective by seasoned practitioners, is especially helpful.
The report did not hide from reporting the limitations of current research either. Most of it has only been done on a small scale by a small group of people rather than a broader population. This has limited the conclusion from a broader perspective.
The report has also recommended, in different social and physical environments and with participants in other demographic groups and socioeconomic characteristics, including the influence of different intergenerational interactions.
The study showed an intelligent response to age stereotypes, alongside policy, law, educational intervention, and effective strategy.

Our desire to hibernate and stay at home, feeling cozy in the middle of winter, is well expected. A brisk hike in the cool, fresh air is the perfect remedy for being cooped up indoors.
The winter season is usually bleak, peaceful, and breathtaking. There might be fewer people on the trail, which means you could see more wildlife. Additionally, according to Dr. Stuart Harris, head of Massachusetts General Hospital's Division of Wilderness Medicine, it's a fantastic chance to interact with the changing seasons and the living world around us. However, he points out that a multi-mile hike in difficult, icy conditions is very different from hiking in warm weather and calls for careful attention to safety and health. Before you go winter hiking, be aware of the following:
Before going on winter hiking, always put safety first.
When hiking in the winter, you need a totally different strategy, which is different from hiking during the summer season, and this is because the terrain is a little harder. However, it allows us to fully engage with the living environment around us. It is a part of our long history.
Prioritizing safety is very important, especially when traveling with people of varying ages and skill levels, such as elderly relatives or young children. For everyone to have fun and stay safe, it's important to have the right equipment and mindset.
How to Plan and Prepare for Winter Hikes
Make sure you are well-prepared ahead of time, particularly if you will be going with individuals of varying levels of fitness. Carefully prepare your itinerary.
Elderly or very young people are more susceptible to freezing temperatures, and hiking in the winter can be more physically demanding. Winter conditions can be harder on the heart than a perfectly-temperatured day," explains Harris. Consider the physical limitations of each member of your group and allow them to guide your actions. The goal of the exercise is to have fun, not to punish yourself.
Before setting out for hiking:
Dr. Harris suggests that you plan your route in terms of knowing the distance, height, and route. You should also review the local forecast for the hiking area and consider factors like wind speed and chill. The weather can change drastically in an hour, especially at higher elevations, so be aware of what to expect in terms of temperature and precipitation.
Make sure you know if you'll have access to emergency cell coverage if anything goes wrong.
Never go hiking without sharing your plans with someone. This is extremely important. If you are missing something or have an injury that affects you during your hike, the team can give you an idea of where to start looking. Fill out trailhead registers so park rangers will also know you're on the trail in case of an emergency.
If you are staying with one of two of your family members, then there are chances that they must have offended you, or you must have offended them. When you are stressed or angry, it is very unlikely that you will say words that are unkind and lash out at someone you care about. We all make thoughtless mistakes.
Not sure if you should apologize?
It is important that you apologize to someone you have offended or injured, even if you don't think your actions or words were particularly offensive or if you think the other person was at fault. "You have to let go of concerns about right and wrong and try instead to understand the other person's experience in order to preserve or re-establish connections with other people," says Dr. Ronald Siegel, an assistant professor of psychology at Harvard Medical School. This skill is fundamental to emotional intelligence, which is the foundation of all positive, fruitful relationships.
How do you genuinely apologize?
For an apology to be effective, it has to be genuine. Making an accepted and successful apology acknowledges responsibility by accepting that your actions caused the other person pain that was not good. You want to express to yourself that you truly feel sorry and care about the person who was hurt. Make amends immediately or later, but do not make promises you cannot keep.According to the late psychiatrist Dr. Aaron Lazare, who is an apology expert and former chancellor and dean of the University of Massachusetts Medical School, a good apology has to contain these four elements:
Acknowledge the offense you have committed. Take responsibility for the offense, no matter whether it was physical or psychological harm, and assert that your behavior was not acceptable. Avoid making an apology in a way that downplays the pain or raises doubts about whether the victim was truly harmed, as well as using evasive or ambiguous language.
Explain what happened. Explain what happened without excusing it. In fact, sometimes the best strategy is to say that there is no excuse for what you have done.
Express remorse and be real about it. If you feel sorry or ashamed about your actions and errors, this is all part of expressing how remorseful you are.
Offer to make amends if you can. A good example is if you destroy someone's property, repair it, or replace it.
Example of a heartfelt apology
I am sorry for my outburst last night. Even if I've been working under a lot of stress, my actions are not justified or acceptable. I love you, and I promise not to vent my frustrations on you again.
It is 2024, and if you are thinking of starting a new fitness challenge, eat healthier to improve your health. It is a great decision and step to take. Just so you know, there is nothing wrong with doing better or setting good goals.
There are few medical treatments that have shown the health benefits of exercising regularly. You need to decide what type of exercise is best for you, but how do you decide? You can get advice from your doctor or your personal trainer. It is also good to educate yourself about fitness by reading books or following trusted exercise classes.
Many people always scroll through social media, seeing lots of engaging fitspirational posts, which might not always be the best strategy. A new study suggests that you should rethink this strategy.
What is fitspiration?
Fitspiration is a social media post that is made with the intention of inspiring physical fitness and promoting good health. You can find fitspirational posts on different popular social media sites like TikTok, Instagram, Facebook, Tumblr, and YouTube. They usually include beautiful images and videos of people giving advice on food and exercise, as well as inspirational sayings and quotes.
If you search for #fitspiration (or related hashtags like #fitspo) on Instagram alone, you will see close to 100 million posts at the moment. The majority of them show pictures of fit, attractive, and slender ladies working out while discussing fitness and maximizing health.
Why is fitspiration a problem?
The pro-fitness message that millions of individuals see might have positive benefits. But the message needs to be credible and from a valid source. Importantly, posts shouldn't provide false, damaging, or ineffective information. Which is the problem with fitpiration.
Social media fitness has effects, and according to research, when you are focused on realistic exercise goals rather than appearance, These posts have their sides and downsides for those watching, which include:
Being dissatisfied with their body
Poor mood and negative false feelings
Thinking they are not attractive
Accepting that being thin is ideal and the only beauty standard accepted.
More focused on their appearance than function and capability.
A study of #fitspiration: Do these social media updates genuinely motivate exercise?
The fitspiration hashtags that are used by Instagram influencers to rate the quality of their posts. A recent study carried out showed some disappointing results, but these weren't surprising.
100 Fitspiration influencers on Instagram were listed by the writers. The last 15 posts made by each of these accounts were checked, and these posts were untrustworthy.
- They showed nudity or revealing clothing by wearing bikinis at the gym.
- sexualized the person exercising, such as by focusing on a woman's breasts or buttocks.
- Included are pictures of people with extreme body types, like those who are excessively muscular or terribly underweight.
- They did not focus on health; their messages promoted thinness or other negative messages.
- contained fitness information in three or fewer posts out of 15.
