A2B Tricycle for Disabled Children
Shabtai Hirshberg from School of Practical Engineering at Hadassah College Jerusalem designed this trike to encourage physical activity among kids suffering from neurological or muscular disorders. Yanko Design, the most excellent design blog, explains how the device works:
Conceived after visiting a children's hospital in Jerusalem, designer Shabtai Hirshberg created the A2B trike so disabled kids could mount and ride by themselves. When a child mounts the trike, stepping on the pedal locks the wheels, enabling the child to literally walk right into a seated position. The chest support keeps the child stabilized, and the whole trike can be customized to each child's needs.The gear based rear wheel makes it easy for the child to pedal since less force is required to drive the system. The entire steering shaft is cable driven so very small movements translate into larger ones.If you're wondering why disabled children are riding trikes, it's more than a recreational activity. Hospitals around the world use it for rehabilitation, promoting independence, muscle development, and balance.

Virtual Reality Walking Motivator
Wendy Powell, a PhD student in the School of Creative Technologies at the University of Portsmouth has created a walking simulator that works in conjunction with a treadmill to fool the walker into believing he or she is walking slower. The idea is to motivate the physical therapy patients to speed up.
Clinical trials on real patients are taking place in collaboration with experts at the renowned McGill University in Canada where early results are encouraging.A former chiropractor, Wendy, hopes it will pave the way for a new and innovative approach to physiotherapy.
She said: “The virtual system encourages patients to walk more quickly and for longer, almost without them realising it. We’re effectively fooling the brain and the body.
The environment is stimulating and entertaining and there’s less fear of falling over. Our test subjects are usually surprised when I tell them they’ve improved by up to 20 per cent.”
Wendy hopes that the system will also help older stoke patients who often find traditional approaches to improving their speed and distance difficult because it relies very much on self-motivation.
She said: “After a stroke or fall many older people lack motivation and confidence and they don’t feel steady on their feet so getting out and about can be an issue and they can find the whole process rather dull.”
Wendy’s system uses a variety of different images from urban landscapes to forest and mountain scenes. She has built a system of rewards into some of the programmes, which encourages the patient to pick up objects and collect points. She said that older people were not at all put off by the ‘computer game’ element but seemed to enjoy it.

Neuro-Eye Therapy, a Vision Training Program, Improves Sight of Stroke Victims
At the University of Aberdeen in Scotland a new program has been setup to help restore vision in patients that lost part of their ability to see due to a stroke.
From the press release:
Dr Arash Sahraie, Reader in Visual Neuroscience at the University of Aberdeen, explained: "The basic principles behind Neuro-Eye Therapy are similar to those of physiotherapy following a stroke. If muscles are affected following brain injury, patients are asked to repeat a pattern of limb movements in order to improve their mobility."In the same way, after daily use of the Vision Rehabilitation ProgramTM over a six month period, patients have reported an improvement in their sight as well as a range of other benefits, including being able to get about more easily, both inside and outside their homes, and finding reading much less of a struggle."
"The device used in Neuro-Eye Therapy is simple to set up in the home or office and requires no prior expertise or experience of computer use," said Dr Sahraie.
"The daily task involves looking at a computer screen and deciding whether or not an image is presented within the blind area by pressing a button. Initially patients can only guess whether the image was presented, but over time patients experience an improvement in their vision."

Force-feedback Offerings from Haption
Via a press release from Virtalis Ltd , a consultancy out of Manchester, UK, we learn about a French company Haption S.A. that is trying to expand the use of its haptic technologies in the medical market, such as for surgical training, rehab, etc.
According to Virtalis,
The Haption range encompasses a small, desktop device with a translational workspace within a sphere of diameter of 120 mm and rotational workspace of 35O in three directions. Top of the range is the Virtuose 6D35-45, which was designed for the 1:1 scale manipulation of virtual objects and has a massive transational workspace up to a sphere of diameter of 450 mm and can exert forces up to 35 N. All Haption products can be easily integrated into Virtalis StereoWorks installations, so that the Haption device is linked to 3D stereo projection in a fully tracked virtual environment.Aside from engineering applications, Haption is finding new customers in the kinehaptic field where patients overcome their injuries by practicing their fine motor skills. Surgeons who need to stay within a tightly controlled operating envelope represent another important market for haptics. So do nuclear engineers, whose complex operations when dealing with several robots carrying out specialized dismantling and decommissioning work, have found themselves benefiting greatly from virtual force feedback. In hazardous environments, being able to create the physics of an object, practice manipulating it, optimize the movement path and then record that path, has proved to be invaluable.

Copying Nature for More Convincing Prosthesis
An EU funded project called SENSOPAC, which aims to develop new artificial robotic limbs, has been mimicking nature to take advantage of what has essentially stood the test of time. The newly built arm in many ways copies the human arm, and the developers are building a microchip brain that they hope to model on certain aspects of ours.
To mimic the skin’s sensing capabilities, researchers at the German Aerospace Centre (DLR), guided by physiology results from Umeå University, in Sweden, created a thin flexible material filled with a form of carbon whose resistance changes with pressure. This approach let them combine information from sensors in different parts of the skin in order to minimise the number of information-carrying wires.“We can soon integrate hundreds of detector elements and get the information out with just five wires,” says van der Smagt [Patrick van der Smagt, coordinator of SENSOPAC --ed.]. “And we have the ability to distinguish between shape, the amount of force, and the direction of force.”
The human arm and hand can generate and control a remarkable range of force, from the delicate touch of a watchmaker to the power of a javelin thrower. Much of this range of force and finesse comes from the pairs of opposing muscles that control each joint.
Researchers at DLR took the same approach. The artificial arm they built and are now experimenting with uses a total of 58 motors in opposing pairs, coupled with non-linear springs, to control the arm.
The hand they have built is closely modelled on the human hand. It can snap its fingers, pick up an egg or carry a cup of coffee. Its fingers are moved by 38 opposing motors.
The researchers are currently using software to simulate important aspects of how the cerebellum processes and integrates information.
“It’s the first neural-network-based controller that can control the dynamics of a robotic system in its full operational range,” says van der Smagt.
In the next six months, they will be seeing how well this system can learn to control the arm.

A Slam-Dunk Design for a Wheelchair
When they were students at the University of Illinois, Ricky Biddle, Eric Larson and Ben Shao decided to do something for the disabled athletes involved in wheelchair basketball. This sport is inherently dangerous, and injuries resulting from collisions are frequent. The other intrinsic problem is the need for participants to use hands not only to dribble the ball but to control the wheelchair. So the three chaps teamed up with Austin Cliffe, another designer, and have come up with a prototype Balance Sport Wheelchair, now Gold winner of the 2008 International Design Excellence Award in Medical & Scientific Concepts category.
Ricky Biddle gave us the following explanation:
The design solution uses a braking system that is activated by the user’s movements in an intuitive way. To turn, the player leans in the desired direction. To stop, the player simply leans back.Every athlete is different. Add a wheelchair to the equation and these disparities multiply exponentially. On top of size differences, personal preferences and so on, wheelchair athletes also have different injuries and unique challenges and mobility limitations associated with their injury. This meant designing a solution that would meet the needs of people with varying levels of skills and abilities.
After testing simple mechanisms and methods of braking, it became clear that the brakes and the leaning mechanism would have to be extremely flexible and be able to be tuned to accommodating the various needs and preferences of players. Disc brakes allow for adjustability that is as simple as turning a dial and for independent adjustment of the left and right wheels. The disc brake system isolates most of the contributing variables of what could be a complicated braking system into two small, easily adjustable units.
The designers spent a great deal of time and effort addressing the points of rotation to find the optimal ergonomic solution. In an attempt to aid players with mobility only from the shoulder up, the left-to-right point of rotation was placed at the middle of the back in prototypes, but it quickly became apparent that this solution was too sensitive. A very slight lean could cause the brakes to engage suddenly, and players with limited means to control their leaning would be jostled around in a jerky turn. What should have been one smooth action became several shorter brake, brake, brake motions. After many attempts to dial this in, it became apparent such a short throw was more of a detriment than an aid to players with low mobility. We observed that left-to-right leaning by athletes with greater mobility involved a shifting of weight from one buttocks cheek to the other. This resulted in a linkage type of rotation, rather than the one-point center rotation that we had considered. We placed two pivot points under the seat. The longer throw also results in a less touchy mechanism, giving players of all abilities a smoother lean/turn braking operation. Two points of left and right rotation add further to the adjustable resistance of the leaning resistance.
The leaning of the seat back to actuate the brakes also allows for adjustable resistance for athletes of different abilities. Player with little mobility can set a high resistance of their seat’s lean and adjust their brake resistance to allow very slight movement to give them the desired braking and turning response. Players with more mobility, on the other hand, may prefer a looser setting to allow their upper body to move more freely and fluidly without inadvertently braking or turning.

Video of ReWalk Exoskeleton System
Israel21C has a video of the ReWalk exoskeleton system, from Argo Medical Technologies, for people with paralyzed legs. We profiled the system back in March, and we thought this video would be interesting to see the device in action:
From Israel21C:
ReWalk comprises a light wearable brace support suit which integrates DC motors at the joint, rechargeable batteries, an array of sensors and a computer-based control system. It fits the body snugly to detect upper body movements, which are used to initiate and maintain the walking process. Wearers also use crutches for stability and safety.ReWalk is undergoing clinical trials in Israel at the Rehabilitation Hospital at Chaim Sheba Medical Center - Tel Hashomer, with pilots planned for rehab centers in Holland and Italy. A US trial is scheduled to begin in November at the Moss Rehabilitation Center in Philadelphia, after which Argo will apply for FDA regulatory approval.
Argo's demo video features team member Radi Kioff, a 40-year-old Druze Israeli citizen who was shot in the back while serving in the Israel Defense Forces during the first Lebanon War. Ironically, the man who devised the system that allows Kioff to walk cannot benefit from his own invention. A quadriplegic, Amit Goffer has only partial use of his hands, but not enough to operate the ReWalk.

Tongue Controller Promises Better Device Interaction for Severely Disabled
A novel tongue controller designed for the disabled to operate computers, wheelchairs, etc., is being developed at Georgia Tech. The device uses two magnetic field sensors to detect the movement of a small magnet attached to the tongue, which in turn send data to a control computer for interpretation.
Movement of the magnetic tracer attached to the tongue is detected by an array of magnetic field sensors mounted on a headset outside the mouth or on an orthodontic brace inside the mouth. The sensor output signals are wirelessly transmitted to a portable computer, which can be carried on the user’s clothing or wheelchair.The sensor output signals are processed to determine the relative motion of the magnet with respect to the array of sensors in real-time. This information is then used to control the movements of a cursor on the computer screen or to substitute for the joystick function in a powered wheelchair.
The system can potentially capture a large number of tongue movements, each of which can represent a different user command. A unique set of specific tongue movements can be tailored for each individual based on the user’s abilities, oral anatomy, personal preferences and lifestyle.
“An individual could potentially train our system to recognize touching each tooth as a different command,” explained Ghovanloo [Maysam Ghovanloo, assistant professor at Georgia Tech School of Electrical and Computer Engineering --ed.]. “The ability to train our system with as many commands as an individual can comfortably remember is a significant advantage over the common sip-n-puff device that acts as a simple switch controlled by sucking or blowing through a straw.”
Ghovanloo’s group recently completed trials in which six able-bodied individuals tested the Tongue Drive system. Each participant defined six tongue commands that would substitute for computer mouse tasks – left, right, up and down pointer movements and single- and double-click. For each trial, the individual began by training the system. During the five-minute training session, the individual repeated each of the six designated tongue movements 10 times.
During the testing session, the user moved his or her tongue to one of the predefined command positions and the mouse pointer started moving in the selected direction. To move the cursor faster, users could hold their tongue in the position of the issued command to gradually accelerate the pointer until it reached a maximum velocity.
Results of the computer access test by novice users with the current Tongue Drive prototype showed a response time of less than one second with almost 100 percent accuracy for the six individual commands. This is equivalent to an information transfer rate of approximately 150 bits per minute, which is much faster than the bandwidth of most brain-computer interfaces, according to Ghovanloo.

Mobile Rehab Monitoring With a Cell Phone
Queensland University of Technology researchers wired together a mobile phone, a GPS receiver, and an ECG unit to create a device that can closely track a patient's rehabilitation regiment. Specifically focused on post MI patients, the unit can remotely transfer ECG as well as the speed and walking incline data to a monitoring clinician.
"The program allows people who have been in hospital for a heart attack or heart surgery to undergo a six-week walking exercise rehabilitation program wherever it's convenient, while having their heart signal, location and speed monitored in real time," Dr Worringham said."We are trying this approach because 80 per cent of cardiac patients never complete recommended hospital outpatient rehabilitation programs, despite the fact that they cut recurrent heart attacks by 17%, substantially reduce deaths, prevent re-hospitalisation, and improve both function and quality of life."
"It's not because they don't want to take part, it's usually because they cannot get to the hospital's program easily, because there simply isn't one nearby, or because work or family commitments take priority."
Dr Worringham said country singer and songwriter Alan McPherson was one of the first to trial the system.
"Mr McPherson was able to do his rehabilitation sessions while on tour from Queensland to Victoria knowing he was being properly monitored," he said.
"Without the system he would have either had to cancel his tour, forego the rehab program, or take a chance and exercise with no monitoring or support."
The Cardiomobile system works by the patient attaching to their chests a mini ECG (electrocardiogram or heart signal) monitor and wearing a cap with a lightweight GPS receiver, both connected to a mobile phone via Bluetooth.
"Patients phone in at the start of their scheduled session and then their heart signal, location, speed and gradient are monitored in real-time over the web by a qualified exercise scientist, who guides the patient's program and checks their progress," Dr Worringham said.
"If there is any problem with the heart signal we can immediately contact the patient, and consult with the cardiologist if needed.

A More Natural Prosthetic Foot
While still in its prototype phase, the Tensegrity foot is designed to mimic the action of a jointed foot to allow for a more natural and stable gait. Built by inventor and mechanical engineer Jerome Rifkin, the artificial foot bends like a normal foot and ankle, and conforms to the terrain underneath it. The prosthetic options for foot amputees is limited due to the complexity involved in mimicking the weight-bearing action and propulsion involved with the foot. Mechanical prosthetics often do not mimic the motion of a natural foot, and other prosthetics cost a significant amount and are not covered by insurance.
The Tensegrity foot is different. POPSCI explains:
Rifkin built something that combined the natural step of a bionic foot with the simplicity and low cost of a mechanical prosthetic. His jointed foot has a heel, a forefoot, a big toe—and no joint at the ankle. Instead, a novel midfoot joint, which connects the heel and forefoot, does the job of both the ankle and the arch. Like an ankle joint, it flexes up and down to give the wearer a more natural step. And, like a real midfoot joint, it creates a flexible arch in the middle of the foot. A spring and cable connect it to a second joint at the toe, to create extra push-off at the end of each step. Other tensioned steel cables serve as the tendons and ligaments that govern its range of motion—the user doesn’t control it, it simply responds to the pressure of walking. Because the front and back of the foot can move independently, it can react to uneven terrain.With input from 11 amputee test users like Link, Rifkin is refining his fifth (and, he hopes, final) prototype, made primarily of magnesium for its strength and low weight. Early results indicate that the one-pound foot reduces the amount of energy required for each step because it uses the force absorbed by the spring and joints to help propel the foot forward. “It’s the equivalent of taking a 50-pound pack off your back,” he explains. That’s on par with the best bionic feet, without all the expensive motors and artificial intelligence."

Electric Muscle Stimulation with NeuRx Diaphragm Pacer: More Natural Breathing Without a Ventilator
The FDA has given clearance to Synapse Biomedical, Inc. (Cleveland, Ohio) to market their NeuRx Diaphragm Pacing Stimulation system for people with spinal cord injury. The device, that is typically implanted through minimally invasive laparoscopic surgery, is indicated for patients with diaphragm dysfunction.
The new device, already approved in Europe last year, uses electrodes attached directly to the diaphragm to electrically stimulate its movement. The result is more natural breathing, and, hopefully, reduced potential to develop pulmonary complications.
From the press release:
In the clinical trial, NeuRx DPS™ provided 98% of SCI patients who had been dependent on mechanical ventilation via a tracheostomy with an alternative that allowed them to breathe normally and live more active lives. To date, over 50% were able to be completely eliminate their need for mechanical ventilation. Patients may be able to transfer from ventilator wards to home or assisted living, and even travel. Speech patterns, often laborious and strained in ventilatordependent patients, return to normal. The senses of taste and smell, severely diminished in ventilatordependent patients, return.Controlled through a fourchannel battery powered external pulse generator, the NeuRx DPS™ eliminates the need for a source of electricity and the concern for power outages. Patients and caregivers are easily trained in the use of the NeuRx DPS™ reducing the need for external medical supervision. Elimination and reduction of the use of a mechanical ventilator also greatly reduces the patient’s risk of a serious complication: Ventilator Acquired Pneumonia (VAP). In a peer review 2007 report in Physical Medicine and Rehabilitation Clinical of North America by Stephen P. Burns MD, the incidence of SCI pneumonia for initial admitted patients was reported to be as high as 50 percent. The associated mortality from pneumonia was reported as 28% in the first year.

Real Exercise for a Virtual World
A couple Dutch tinkerers, with the understanding that many of us already live in Second Life, spliced an exercise bike with a computer. The system now allows a user to control an avatar while getting some real life exercise at the same time.
From the project page:
The first prototypes have been built using conventional hometrainers. These hometrainers are equipped with sensors for measuring velocity and driving direction. Using the same optical sensors also the steering direction is measured. The data is transferred to a PC using the standard PS2 keyboard interface. With a PS2-USB adapter the hometrainer can be connected to a wide variety of systems, (MS Windows, Linux, MAC).The forward velocity and steering direction are measured using optical sensors which can easily be integrated into the existing hardware. Conversion of sensorsignals to PS2 standard is done using an AVR-RISC microcontroller van Atmel.
The bike steer is equipped with an 'ET-button®' (named after a legendary scene in a Spielberg movie). This button is for initiating the flying mode.

ERGYS2 Shows Positive Results as Exercise Option for Paraplegics
MTB Europe is reporting about a study conducted on paraplegics using an electric muscle stimulating training system from Therapeutic Alliances Inc. out of Fairborn, Ohio, a device called ERGYS2. One of the early adopters of this system was the late Christopher Reeve.
In an exercise study completed last year, patients who were paralysed from the chest or waist down experienced an average increase in their oxygen uptake by 25% and in their heart pumping volume by fully 37% after just eight weeks of training.Never before has so much improvement or such impressive results been documented in this patient group.
The Ergys 2 is a stationary training bicycle, where the patient’s legs and feet are strapped to a leg holder and pedals. Electrodes are then fastened to the patient’s thigh and seat muscles, and electrical impulses trigger the muscles to contract and relax.
The impulses are computer controlled to guarantee the best possible effect. Even though it may seem like artificial training, it is real enough as it’s the patient’s own muscles that are working. And it is movement that demands energy: the blood flow increases, and the pulse goes up. The exercise has an effect on muscle mass, muscle strength, oxygen uptake and the heart’s pumping volume.

Mechanical Hand With an Extra Sense of Touch
Intel researchers are showing off electrolocation technology implemented into a mechanical hand, a system that allows artificial fingertips of the hand to sense the presence of objects around them, before making physical contact. Essentially this may provide for faster response movements of mechanical prostheses, and is another sign that artificial limbs are overtaking our natural ones, be it strength, agility, or sensing features. The technology could also one day be incorporated into all kinds of haptic surgical robotic devices.
