Tunisian Startup Creates 3-D Printed, Customized Bionic Hands

Published

on

A 3-D-printed bionic hand is in development by a Tunisian startup that hopes to provide an affordable solar powered prosthetic for amputees and disabled people all over Africa.

The artificial hand beats traditional prosthetic devices with its capacity to be customized for youths and children who would otherwise need expensive resized models series as they grow up.

The Cure Bionics Company intends to develop a virtual game-like reality system to educate youngsters on how the artificial hand functions via physical therapy.

The 28-year-old founder Mohamed Dhaouafi, CEO and founder of Cure Bionics, planned his prototype in Souse, where he was an engineering student.

‘’One team member had a cousin who was born without a hand and whose parents couldn’t afford a prosthesis, especially as she was still growing up,’’ he said.

‘’So we decided to design a hand.’’

In 2017 at his family home, Dhaouafi launched his start-up. Many of his classmates were moving abroad to gain international experience and earn more money, but Dhaouafi chose a different path.

‘’It was like positive revenge,” he told AFP. ”I wanted to prove I could do it. I also want to leave a legacy to change people’s lives.”

Dhaouafi pointed at Tunisian hurdles that made it near impossible to buy parts from online large sales sites. There wasn’t enough funding and, he said, ‘’We lack visionaries within the state.’’

Dhaouafi combined the money he raised from sponsored competitions and seed capital an American company awarded him and managed to recruit 4 young engineers.

Now they are perfecting designs, trying out the prosthetic hand, and writing code.

‘Climb like Spiderman’

The device works with sensors attached to the arm which detect muscle movement, with AI-assisted software and interprets this movement then transmits instructions to the digits.

The bionic hand is equipped with a wrist that can turn sideways, fingers that respond to electronic impulses and bend at the joints, and a mechanical thumb.

Teaching youngsters how to use them, Cure has had to work on a virtual-reality headset, which ”gamifies” the process of physical therapy.

”Currently, for rehabilitation, children are asked to pretend to open a jar, for example, with the hand they no longer have,’’ said Dhaouafi.

‘’It takes time to succeed in activating the muscles this way. It’s not intuitive, and it’s very boring.’’

In Cure’s description, the engineer said: ‘’We get them to climb up buildings like Spiderman, with a game score to motivate them, and the doctor can follow up online from a distance.’’

Meanwhile, 3-D printing makes it easy to personalize prosthesis with a fashion accessory or ”a superhero’s outfit,’’ said Dhaouafi.

Cure hopes to take the bionic hand to the market within months within Tunisia and the rest of Africa, where over 75% of people who need them cannot access them, according to the World Health Organization.

‘’The aim is to be accessible financially but also geographically,’’ said Dhaouafi.

The anticipated substantial price of between $2,000 to $3,000 is just a fraction of bionic prostheses cost currently imported from Europe.

‘Leapfrog Technology’

Cure aims at manufacturing the closest possible to end-users, where local technicians measure the patient’s and then print custom made-to-order devices.

‘’An imported prosthesis today means weeks or even months of waiting when you buy it, and again with each repair,’’ the inventor said.

The bionic hand is built from detachable parts that are easy to replace when damaged.

It could also be run with solar energy through a photovoltaic suitable for regions with unreliable electricity.

The rudimentary prosthesis 3-D printing started around a decade ago, and it’s becoming standard.

The solution is not magic since specialized medical skills are very vital, observed Jerry Evans, the Nia Technologies head, a non-profit organization from Canada that helps hospitals in Africa manufacture 3-D-printed lower extremities.

3-D printing is still in its early stages,” he said, ”but it is a major game-changer in the field of prosthetics and orthotics.”

‘’Developing countries will probably leapfrog to these technologies because the cost is much lower.’’

The Dawn of AI-Enhanced Rehabilitation: How AI-Powered Trousers are Revolutionizing Stroke Recovery

Published

on

By

In the quaint town of Penarth, Vale of Glamorgan, a remarkable story of resilience and technological innovation is unfolding. Julie Lloyd, a 65-year-old stroke survivor, is relearning to walk, aided by a groundbreaking piece of technology: trousers powered by artificial intelligence (AI). This pioneering trial in the UK marks a significant leap in medical technology, offering new hope to stroke victims worldwide.

The Breakthrough in Stroke Rehabilitation

Julie’s journey is not just a personal triumph but a beacon of hope for millions affected by strokes. According to the World Health Organization, strokes are the second leading cause of death globally, and the leading cause of acquired disability among adults. The road to recovery is often long and arduous, with traditional rehabilitation methods providing varying degrees of success.

The AI-powered trousers represent a paradigm shift in rehabilitation technology. As Julie puts it, “I really feel this is the breakthrough for stroke victims that has been much and long awaited for.” This sentiment echoes the sentiments of many in the medical community who have long sought more effective ways to aid stroke recovery.

How the Technology Works

The AI trousers are a marvel of modern engineering and medical science. They function by using a series of sensors and motors that work in tandem with the wearer’s movements. This technology is not just about physical support; it’s about enhancing the body’s natural ability to relearn movements. The AI component analyses the wearer’s gait, providing real-time adjustments to improve walking patterns, much like a physical therapist would.

This approach is grounded in the concept of neuroplasticity, the brain’s ability to reorganize itself by forming new neural connections. By assisting in the correct movement patterns, the trousers help the brain to ‘relearn’ walking, potentially speeding up the recovery process.

The Impact on Stroke Rehabilitation

The implications of this technology are vast. For stroke survivors, the journey to recovery can be filled with frustration and despair. Traditional rehabilitation methods can be slow and, at times, ineffective. The AI trousers offer a more dynamic and responsive form of therapy that could revolutionize how we approach stroke rehabilitation.

In a study conducted by the American Stroke Association, it was found that early and individualized rehabilitation can significantly improve outcomes for stroke survivors. The AI trousers align perfectly with this philosophy, offering a tailored rehabilitation experience that adapts to the individual’s needs.

Challenges and Future Prospects

Despite the promise, the road ahead for AI in medical rehabilitation is not without challenges. Cost and accessibility are significant concerns. Cutting-edge technology often comes with a high price tag, potentially putting it out of reach for many who could benefit from it.

Moreover, there’s the challenge of integrating such technology into existing healthcare systems. As noted by experts in healthcare technology, the adoption of new medical technologies often faces hurdles in terms of regulatory approval, practitioner training, and patient acceptance.

However, the future looks bright. As AI and robotics continue to advance, we can expect these technologies to become more affordable and widespread. The potential for AI to aid in various aspects of healthcare, from diagnosis to treatment and rehabilitation, is enormous.

Conclusion

Julie Lloyd’s story is just the beginning. As we stand on the cusp of a new era in medical technology, the possibilities are endless. The AI-powered trousers are more than just a piece of technology; they are a symbol of hope and a testament to human ingenuity. For stroke survivors around the world, this could be the dawn of a new day in rehabilitation, one where technology and human resilience come together to create new possibilities.

By

Artificial Intelligence (AI) is making inroads into various sectors, and healthcare is no exception. According to a recent NPR article, Dr. Michael Mansour of Massachusetts General Hospital is among the early adopters testing an AI-enhanced version of UpToDate, a widely-used medical database. This experimental version employs generative AI to provide doctors with more targeted information, aiming to streamline the diagnostic process.

Wolters Kluwer Health, the company behind UpToDate, is working on making the database more conversational, allowing doctors to maintain the context of their queries. While the technology is still in beta and has some kinks to work out, the potential is enormous. AI could not only assist in making accurate diagnoses but also free up doctors’ time, allowing them to focus more on patient care. As Dr. Marc Succi of Mass General Brigham aptly puts it, “AI won’t replace doctors, but doctors who use AI will replace doctors who do not.”

A New way around Drug Resistant Tuberculosis

Published

on

By

Researchers at Purdue University have created a powerful compound that specifically tackles Tuberculosis, a leading killer worldwide.

The scientists came up with a series of inhibitors that destroy TB by targeting a protein necessary for the survival of the TB molecule.

Tuberculosis destabilizes the immunity of patients with the help of Protein Tyrosine Phosphates B (mPTPB). Their findings were published in the Journal of Medicinal Chemistry.

“The death toll from TB is particularly high because of drug-resistant strains,” said Zhong-Yin Zhang, distinguished professor and head of Purdue’s Department of Medicinal Chemistry and Molecular Pharmacology and director of Purdue Institute for Drug Discovery. “These inhibitors are part of a promising new approach to developing TB therapeutic agents with novel targets and mechanisms of action to help save more lives.”

Right now, doctors rely on antibiotic preparations to treat Tuberculosis. The problem is that many patients don’t complete their dose of antibiotics and this non-adherence leads to the development of drug resistant tuberculosis.

“We developed a platform to target mPTPB for novel anti-TB agents that builds on technologies we pioneered to modulate abnormal protein tyrosine phosphatase activity for the treatment of diseases such as cancer, diabetes and autoimmune disorders,” Zhang elaborated.

According to Zhang, the inhibitors’ have unique properties that make them incredibly useful. They have a lighter molecular weight and superior metabolic stability. They give scientists an excellent opportunity to create better treatments for Tuberculosis.

The visionary scientists are already working to patent the exciting new technology. The hunt is on for partners who will work with Purdue to further the development of the new technology. This is together with the Purdue Research Foundation Office of Technology Commercialization.
