A Doctor of Medicine Explains Rehabilitation and Digital Technology (Part 3)
The First Part: MELTIN's Robotic Neurorehabilitation for the Fingers
Innovations in Rehabilitation Brought by Cyborg Technology
Advanced Robot Technology in Neurorehabilitation
The number of stroke patients in Japan is approximately 1.12 million1), and motor paralysis, which is a typical sequela of stroke, makes it difficult for patients to return to work, return to society, and achieve independence in daily life. In addition, upper limb functions are often harder to recover in stroke patients with hemiplegia than in those with lower limbs2), making it difficult for many to return to society because they “cannot write, use a personal computer, or do household chores.” For stroke patients with hemiplegia, how well they can restore upper limb paralysis through rehabilitation is a challenge that will significantly affect their rest of life.
In recent years, robots that assist in upper limb neurorehabilitation*1, such as robots that use electrical stimulation to help in repetitive facilitation exercise*2 and robots that improve paralysis by repeatedly performing set reaching movements*3, are made available. Among these, the “robotic neurorehabilitation device for the fingers” from MELTIN MMI (hereafter “MELTIN”) has attracted particular attention and is expected from the clinical settings.
MELTIN's Cyborg Technology
MELTIN, founded in 2013, has a vision of “Unleashing human's physical limitations through Cyborg Technology and embodying a world where everyone can make their dreams come true regardless of age or physical condition.” They are engaged in research, development, and commercialization of medical devices and avatar robots that utilize bio-signal processing and robot technologies. In addition, MELTIN's business using cutting-edge cyborg technology has attracted tremendous attention, winning the Excellence Award and Jury Special Award at the Bank of Tokyo-Mitsubishi UFJ “Rise Up Festa” in 2016 and the Semi-Grand Prix in the Devices/Technologies Category at CEATEC AWARD 2018. In particular, MELTIN has great technologies in “bio-signal processing” and “robot mechanism control” and is expected to be an innovator in robotic rehabilitation.
The avatar robot developed by MELTIN “MELTANT-α CAPABILITIES”
MELTIN has developed a unique bio-signal processing algorithm that allows highly-accurate, real-time analyses of diverse bio-signals. It means that we can perform very complex movements instantly and operate the robot intuitively without special training. In addition, the robot hand control mechanism, inspired by copying the human hand, reproduces the human hand's complex movements in a wire-driven manner. It enables the robot to perform strong and delicate movements, which would never have been possible using traditional robotics but with the same size and weight as a human hand.
Robotic Neurorehabilitation Device for the Fingers
MELTIN's “Robotic Neurorehabilitation Device for the Fingers” has been realized by integrating “Analysis technology using AI” to “Bio-Signal” and “Robot Control.” Analyzing complex myoelectric data*4 using our original AI algorithms make it possible to instantly identify the intended movements and offer motor assistance connected to effective rehabilitation.

“THE VISION of MELTIN” Source: MELTIN MMI
MELTIN MMI is expertise in R&D and commercialization of medical devices and avatar robots by using bio-signals in order to develop bio-signal processing technology and avatar robot technology. Because our ultimate goal is to realize Cyborg Technology that is well known as artificial body and brain-machine interface (interface between brain and machine) for unleashing human's physical limitation and maximizing our creativity for embodying a world where everyone can make their dreams come true.
