by The field of medical exoskeleton technology has seen tremendous advancements in recent years. What were once concepts of science fiction are becoming a reality to help improve mobility and independence for people with disabilities. In this article, we will explore the growing use of exoskeletons globally and the promise they hold to enhance people’s lives.
An Emerging Technology
Medical exoskeletons first began development in the early 2000s but have seen huge leaps in the last decade. Using advancements in materials science, robotics, sensors and batteries, engineers have created powered leg braces and full body suits that augment a person’s strength and mobility. Some key early developments include the Rex bionic leg braces developed by Rex Bionics to help paraplegics walk again and Ekso Bionics creation of the Ekso exoskeleton suit.
Since those initial prototypes, the technology has improved dramatically. Exoskeletons can now offer variable levels of power and support tailored to an individual’s needs and capabilities. Onboard computers and sensors allow for responsive control via the wearer’s movements or commands. Lighter composite materials mean exoskeletons can be worn for hours at a time. Advances continue apace driven by engineering innovations and investment from both private companies and government research programs.
Global Medical Applications
Across the globe, exoskeleton technology is being applied to help people with a variety of mobility challenges. In rehabilitation centers, they are assisting stroke victims and paraplegics to practice walking exercises that accelerate recovery. For amputees, powered leg braces mean regaining independence to walk without crutches or a wheelchair.
For those with degenerative Global Medical Exoskeleton conditions like multiple sclerosis, exoskeletons can stave off permanent wheelchair dependence by preserving muscle function. In manufacturing and warehouse facilities, lower body exoskeletons are helping workers lift and carry heavy objects for extended periods without fatigue or injury. The military is also a major supporter with exoskeleton research programs aimed at helping wounded soldiers rehabilitate and return to active duty.
Even industrialized nations with strong social support systems face aging populations. According to United Nations estimates, one in six people will be over age 65 by 2050. Exoskeletons hold promise to alleviate some of the challenges of elder care by helping the elderly maintain mobility and independence for longer. They could reduce healthcare costs associated with falls and mobility-related diseases. If proven effective, medical exoskeleton adoption could dramatically rise globally as populations age in the coming decades.
Government Support Driving Innovation
Given the potential economic and social benefits, government programs have become vital to developing robust medical exoskeleton technology. The US Defense Advanced Research Projects Agency (DARPA) has committed over $100 million through its Warrior Web program with a goal of fielding medical exoskeleton suits by 2028. This initiative focuses on lower body suits to support active military duties up to 70 lbs of added weight for 12 hours.
Similarly in Europe, the European Commission has provided over €40 million through the ExoHUNTER project to create a soft exoskeleton for assisting forestry and construction workers. The suit uses functional textiles and novel actuation to reduce fatigue from overhead work or heavy lifting. Japan’s Ministry of Economy, Trade and Industry invests billions yearly in human-assistive robotics with a focus on elderly care applications.
Moving forward, growing government interest coupled with private sector commercialization aims to bring exoskeletons from research labs into real world use. With continued innovation and lower costs, medical exoskeletons may become common assistive devices worldwide for people with mobility impairments. This technology holds much promise to positively impact quality of life for millions of individuals.
Regulatory Challenges Ahead
While enthusiasm remains high for the potential of medical exoskeletons, considerable challenges remain before widespread adoption occurs. Chief among these are addressing regulatory issues to demonstrate a device’s effectiveness and safety. Most exoskeletons are still experimental prototypes requiring extensive testing and oversight before clinical or consumer use is permitted.
Regulators will need to establish standardized guidelines for performance metrics, mechanical soundness, power system reliability and electromagnetic compatibility. Thorough protocols will be necessary to evaluate devices over long usage periods and understand failure modes. Given the complexity of powered robotic systems controlling human movement, comprehensive human subject trials encompassing diverse users and applications will be vital to gain market approval.
Meeting such regulatory benchmarks will require coordination between government oversight agencies, research institutions, and industry. It could be five to ten more years before exoskeletons progress beyond niche clinical applications. Continued cooperation across sectors will be critical to overcoming regulatory hurdles in a timely manner and realizing the technology’s full benefits. Standardization efforts through international governing bodies may also be necessary if adoption spreads globally.
The Future is Bright
With dedicated long term development support from both the public and private sectors, the future looks promising for medical exoskeleton technology. Innovations will further enhance functionality, improve customization for individual needs, and reduce system costs. Wireless control, onboard intelligence and lightweight materials will optimize user experience. Major clinical trials are demonstrating clear gains for rehabilitation and mobility preservation.
As real world use expands and the regulatory pathway becomes established, exoskeletons may supplement or replace traditional braces, walkers, and wheelchairs for certain applications. Some predict lower body exoskeletons could reach consumer availability within the next decade to aid elderly mobility. More adaptive applications remain on the horizon such as pediatric exoskeletons to aid child development.
With a growing aging global population, mobility-related healthcare expenses are rising steeply. Exoskeletons hold potential as a cost-effective preventative technology if adoption models can be validated. Although challenges lie ahead, advancements achieved so far inspire optimism that these revolutionary bionic aids can dramatically improve lives worldwide in the coming years. The future of medical exoskeleton technology remains bright as innovators harness engineering to restore human capabilities
