The Future of Prosthetics: A Breakthrough in Bionic Hand Technology

Free Subscribtion

In recent years, advancements in technology have led to groundbreaking innovations in the field of prosthetics. One such breakthrough is the development of the Mia Hand, an experimental bionic hand that has passed a major test with flying colors. This prosthetic, fused with bone and connected to the nervous system, has given its owner a new lease on life and significantly reduced phantom pain. In this article, we will explore the incredible journey of Karin, a Swedish woman who has successfully worn the Mia Hand for years, and delve into the science behind this revolutionary technology.

The Journey of Karin

Karin’s life changed forever over 20 years ago when she suffered a farming injury that resulted in the loss of much of her right arm below the elbow. Like many amputees, Karin experienced phantom limb pain, which required her to rely on high doses of medication for relief. Traditional prosthetics provided little benefit as they were often cumbersome and difficult to use in daily life. However, Karin became one of the first patients enrolled in the DeTOP project, a pioneering research study funded by the European Union. This project aimed to develop the next generation of bionic limbs, offering hope to individuals like Karin.

The Mia Hand: A Cutting-Edge Prosthesis

Karin’s prosthesis, known as the Mia Hand, was created by the Italian company Presilia and is equipped with state-of-the-art technology, including artificial intelligence (AI). To enhance its functionality, her surgeons performed osseointegration during the attachment procedure. This process involves directly fusing the bone to the implant, creating a stronger mechanical connection. Additionally, electrodes were implanted in Karin’s arm muscles and nerves, and some of her nerves were rewired in the remaining part of her arm. The result is a bionic limb that is directly connected to Karin’s neuromusculoskeletal system.

Control and Sensory Feedback

Similar to a real hand, the Mia Hand is controlled by Karin’s nervous system, providing her with sensory feedback. This innovative technology enables her new hand to perform approximately 80% of the tasks that a natural limb would be capable of. Not only has the Mia Hand restored much of Karin’s functional abilities, but it has also significantly reduced her phantom limb pain and the need for medication. The success of the Mia Hand has been documented in the journal Science Robotics, highlighting its potential to positively impact the lives of individuals facing limb loss.

A Promising Future for Bionic Limbs

The case of Karin is just one example of the transformative power of bionic limbs. The DeTOP project, with its multidisciplinary team of scientists across Europe, aims to push the boundaries of what is possible in the realm of prosthetics. While the research on patients like Karin is still ongoing, the hope is that these advanced prosthetics will eventually become the new standard for upper limb amputees. The positive impact on Karin’s life is a testament to the potential life-changing capabilities of this novel technology.


The development of the Mia Hand is a significant milestone in the field of prosthetics. This experimental bionic hand, fused with bone and connected to the nervous system, has provided Karin with a new lease on life and alleviated her phantom limb pain. With its advanced technology and direct integration with the neuromusculoskeletal system, the Mia Hand has restored much of Karin’s functionality and improved her overall quality of life. As research in the field of bionic limbs continues to advance, the future looks promising for individuals facing limb loss, offering hope for a more inclusive and technologically advanced world.
