Revolutionary rehab robotics: A new leap in adaptive gait training

Revolutionary rehab robotics: A new leap in adaptive gait training
2024-08-21
(Press-News.org) In an era where technology increasingly merges with healthcare to enhance patient outcomes, a groundbreaking study conducted by Fuyang Yu and his colleagues introduces an innovative approach to lower limb rehabilitation. Their research, published in Cyborg Bionic Systems, outlines the development of a lower limb rehabilitation robot designed to significantly improve the safety and effectiveness of gait training through a novel method based on human-robot interaction force measurement.

Rehabilitation robots are not new, but the technology behind them continues to evolve. Traditional models often rely on predetermined gait patterns, which may not suit every patient's needs, particularly those with some residual muscle strength. Yu and his team's new robot addresses this by dynamically adjusting its gait in real-time to match the user's intent and capabilities, a significant shift from the more common, passive training approaches.

This robot, developed through collaborative efforts from institutions including the University of Chinese Academy of Sciences and the Institute of Automation at the Chinese Academy of Sciences, features an array of sensors and a sophisticated control system. These components work together to measure the forces exerted by a patient's movements and adjust accordingly, ensuring that the robot's support is neither too little nor too excessive.

The core innovation lies in its adaptive gait training capability. By using face-to-face mounted cantilever beam force sensors, the robot can accurately detect and interpret the subtle forces exerted by the patient during a training session. This data informs a dynamic model that predicts and adapts the robot's movements in real-time, significantly enhancing the training's responsiveness and effectiveness.

The research team conducted extensive testing to validate their design. Results from interactive experiments demonstrated that the robot could significantly improve the training experience by responding to the patient's muscle inputs. This adaptability not only maximizes engagement but also helps to prevent muscle atrophy and improves overall recovery outcomes.

Moreover, this robot represents a promising solution for remote or underserved areas where professional medical and rehabilitation support may be scarce. Its ability to offer personalized training remotely could democratize access to high-quality rehabilitation services, making it a valuable tool in global health contexts.

As healthcare continues to embrace technological advancements, the work of Yu and his team showcases the potential of robotics in enhancing patient care. Their development not only offers new hope for individuals with lower limb impairments but also sets a new standard for the integration of intelligent technology in therapeutic practices. This adaptive approach could well become a cornerstone in the future of physical rehabilitation, paving the way for more responsive and effective treatments.

The paper, “Adaptive Gait Training of a Lower Limb Rehabilitation Robot Based on Human-Robot Interaction Force Measurement ”was published in the journal Cyborg and Bionic Systems on Jun 21, 2024, at DOI:https://spj.science.org/doi/10.34133/cbsystems.0115

Targeted cancer cell therapy may slow endometrial cancer

2024-08-21
There may be a way to slow the growth of endometrial cancer through targeted cancer cell therapy, according to new research from the University of Missouri School of Medicine. This year, around 65,000 women are expected to be diagnosed with endometrial cancer, the most common cancer of the female reproductive organs. An increased risk in development for multiple human cancers is associated with mutations in the PTEN protein, which normally regulates cell division and growth. The mutation allows cells to multiply uncontrollably.  Using mice models, Krystina Dunston, research lab manager and NextGen Precision Health researchers Tae Hoon Kim and Jae-Wook Jeong, studied the ...

Hepatic disease: a camu-camu fruit extract to reduce liver fat

2024-08-21
Québec City, August 21, 2024 – A research team from Université Laval has shown the benefits of camu-camu on non-alcoholic fatty liver disease, which affects over seven million people in Canada. This exotic fruit reduces liver fat levels.   Over 12 weeks, thirty participants took either camu-camu extract or a placebo at different times in this randomized clinical trial. Participants underwent magnetic resonance imaging (MRI) to determine fat levels in the liver. Scientists observed a 7.43% reduction in liver lipids when study participants took camu-camu extract. With the ...

Quenching the intense heat of a fusion plasma may require a well-placed liquid metal evaporator
2024-08-21
Inside the next generation of fusion vessels known as spherical tokamaks, scientists at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) envisioned a hot region with flowing liquid metal that is reminiscent of a subterranean cave. Researchers say evaporating liquid metal could protect the inside of the tokamak from the intense heat of the plasma. It’s an idea that dates back several decades and is tied to one of the Lab’s strengths: working with liquid metals. “PPPL’s expertise in using liquid metals, ...

The power of face time: Insights from zebra finch courtship
2024-08-21
A new study on songbirds sheds light on the power of social interaction to facilitate learning, insights that potentially apply to human development. McGill University researchers discovered that zebra finches deprived of early social experiences could still form strong bonds with a partner later in life. Once placed into cohabitation with a male, females that had never heard a mating song before could quickly develop a preference for his melody. The findings, published in Proceedings of the Royal Society ...

Near-term NASA Mars and lunar in situ propellant production: complexity versus simplicity
2024-08-21
First, lunar ISPP is analyzed from aspects of lunar resources, near-term lunar processes, carbothermal process, polar ice, and reduction of iron oxides. There are basically 4 potential lunar resources: (1) Silicates in regolith containing typically >40% oxygen. (2) Regolith containing FeO for hydrogen reduction. FeO content may vary from 5% to 14%, leading to recoverable oxygen content in the 1 to 3% range. (3) Imbedded atoms in regolith from solar wind (typically parts per million). (4) Water ice in regolith pores in permanently shadowed craters near the poles (unknown percentage but ...
