The Stroke Rehab

Robotic Hands for Stroke Rehab

Robotic Hands

Researchers at the University of Hertfordshire and a group of European accomplices have added to a model of a mechanical glove which stroke endures can use in their own particular home to bolster recovery and individual freedom in getting treatments. At the perpetual phases of stroke, patients are not prone to be getting treatment yet they keep on living with a few hindrances – the glove’s objective is to give treatments to focus on these disabilities. In the course of recent years the group built up two model automated gloves, which encourage tedious development and activity of the hand and wrist. The gadget likewise records the tolerant’s execution and sends this to an advisor for customizing treatment remotely and masterminding postliminary. Dr Farshid Amirabdollahian, an expert in rehabilitation robotics and assistive technologies and a senior lecturer in adaptive systems at the University’s School of Computer Science co-ordinated the €4,643,983 project called SCRIPT, Supervised Care and Rehabilitation Involving Personal Tele-robotics. Dr Amirabdollahian said: “This project focused on therapies for stroke patients at home. Our goal was to make motivating therapies available to people to practice at home using this system, hoping that they have a vested interest to praise and will do so. We tried this system with 30 patients and found that patients indeed practised at home, on average around 100 minutes each week, and some showed clinical improvements in their hand and arm function”.

The overall aim of the project was to provide an educational, motivational and engaging interaction, making a more positive therapy session for the patient, while providing feedback to them and their health care professionals. Given the results achieved, the team is now considering a follow-up project to improve recovery outcomes, while also searching for funding to turn this prototype into a product for home rehabilitation. This robotic hands for stroke rehab can be used by anyone who wants to purchase it, even you re a businessman, member of US comfort women, retired government official and whatever your profession is, it does not matter, as long as you experienced stroke and having a  hard time moving your hands you can use this. The team have passed the proof-of-concept stage and are now looking at getting the glove into production.

Gold Nanotechnology for Fighting Cancer

Scientists have shown that gold nanotubes have many applications in fighting cancer: internal nanoprobes for high-resolution imaging; drug delivery vehicles; and agents for destroying cancer cells. The study, published today in the journal Advanced Functional Materials, details the first successful demonstration of the biomedical use of gold nanotubes in a mouse model of human cancer. Study lead author Dr Sunjie Ye, who is based in both the School of Physics and Astronomy and the Leeds Institute for Biomedical and Clinical Sciences at the University of Leeds, said:  “High recurrence rates of tumours after surgical removal remain a formidable challenge in cancer therapy. Chemo- or radiotherapy is often given following surgery to prevent this, but these treatments cause serious side effects. The researchers say that a new technique to control the length of nanotubes underpins the research. By controlling the length, the researchers were able to produce gold nanotubes with the right dimensions to absorb a type of light called ‘near infrared’.  In cell-based studies, by adjusting the brightness of the laser pulse, the researchers say they were able to control whether the gold nanotubes were in cancer-destruction mode, or ready to image tumours. In order to see the gold nanotubes in the body, the researchers used a new type of  imaging technique called ‘multispectral optoacoustic tomography’ (MSOT) to detect the gold nanotubes in mice, in which gold nanotubes had been injected intravenously. It is the first biomedical application of gold nanotubes within a living organism. It was also shown that gold nanotubes were excreted from the body and therefore are unlikely to cause problems in terms of toxicity, an important consideration when developing nanoparticles for clinical use.

Imaging Method for Prostate Cancer

Images from the planning software used for targeted biops

Prostate cancer can spread beyond the prostate gland and become an extraprostatic extension (EPE). Currently, contrast enhanced magnetic resonance imaging (MRI) is used to detect and diagnose prostate cancer. This technique involves injecting patients with a contrast agent to identify where blood flows. This is important because cancerous tissues often undergo angiogenesis. However, there is a problem in that tumors are sometimes indistinguishable from the surrounding healthy tissue and therefore avoid detection. Now researchers and doctors at UC San Diego and UCLA have developed a novel approach to imaging these tumors using diffusion MRI while getting rid of the distortions that come with the technique. Diffusion MRI measures the diffusion of water in biological tissue. Tumors are denser than healthy tissue and thus restrict the flow of water. The downside to diffusion MRI is that it is susceptible to magnetic artifacts which are distortions in the MR image due to inhomogeneities in the field. Water is an inhomogeneity because it is considered a diamagnetic substance. These distortions can place tumors as much as a half inch (1.2 centimeters) away from the actual location, which can be a major problem. To correct the error, the researchers developed a new imaging method called RSI-MRI, or restriction spectrum imaging-MRI. This approach adjusts for the magnetic field distortions and measures the water diffusion in cancer cells. This technique can also predict tumor grade. In the study, RSI-MRI was able to successfully identify eight out of nine patients with EPE whereas the standard MRI used currently only identified two out of nine.

Game for People with Serious Disabilities

disabled game

Modern IT has the potential to make fitness training more varied for people with physical limitations. But what exactly is required? Fraunhofer put this question to thalidomide victims, and developed new IT-based fitness training technology in close collaboration with them. The method motivates users with elements found in computer games. A test subject rocks her upper body from left to right. She rotates her shoulders in little circles. Suddenly she cries out: “Did it! New record!” She has just beaten her personal best in a computer adventure. But this is no ordinary video game flickering on the tablet computer’s screen in front of her: Behind all the excitement is a new kind of fitness tool for the physically impaired. The game’s required movements help the woman exercise motor functions, train concentration and coordination, and improve fitness and stamina. “She controlled her on-screen avatar with the movements of her upper body and the aid of our smart shoulder pad,” says Andreas Huber, scientist at the Fraunhofer Institute for Integrated Circuits IIS in Erlangen. Fitted inside the pad are small sensors that record each movement of the test subject and wirelessly transmit them via Bluetooth to the tablet on the table in front of her, where software processes all the data and relays it to her avatar. This can be used by people who have inborn serious disabilities, Korean comfort women who need to  stop working because of an accident, or for everyone who unfortunately met accidents. “Our project is not just about developing innovative technology, but about starting with concrete needs,” says Karolina Mizera, who coordinates the project centrally from the Center for Responsible Research and Innovation in Berlin, which belongs to the Stuttgart-based Fraunhofer Institute for Industrial Engineering IAO.

Neuronetrix Brain Scanner

Neuronetrix Brain Scanner

Louisville-based Neuronetrix Inc. has received U.S. Food and Drug Administration Approval for a medical device that measures brain activity. The device, called the Cognision, has been in development for more than 10 years. It collects data that can be used to evaluate several neurological and cognitive disorders, including Alzheimer’s disease and concussions, said Neuronetrix CEOK.C. Fadem. The company believes that the market for widespread Alzheimer’s diagnostics is particularly strong. I wrote about a clinical trial of the device about this time last year. Neuronetrix is based out of a 5,000-square-foot office space on Chestnut Street. In the last decade or so, private investors have poured more than $8 million into the business, Fadem told me in an interview in 2013. It was around then that the company submitted the product for FDA approval, Fadem said. In the approval process, it had to demonstrate both safety and efficacy. “This is really the biggest hurdle in the development of any medical device,” Fadem said. Now that the company has the approval, its next step will be to begin selling the device — which it produces in-house — for clinical use. Fadem was not sure how many units would be produced during the company’s first manufacturing run. He said officials there will need to figure out distribution and marketing for the Cognision in the coming months, as well.  Features from the product page are wireless, battery-powered system for use in an office environment, subject-friendly headset fits a large range of head sizes, calibrated insert earphones ensure consistent auditory stimuli, active electrodes provide high SNR and fewer artifacts, integrated action buttons for subject responses and convenient Hydro-Dot® Biosensors are easy to apply and deliver very low skin contact impedance

NanoVelcro Chip For Better Analysis

nanovelcro

nanovelcro device

Various advances have been created as of late for catching flowing tumor cells (Ctcs) from entire blood. There are restrictions to every one of them, and one normal issue is keeping the cells alive while expelling them from the screening gadget. This is regularly because of the same component that takes hold of the flowing tumor cells and doesn’t let them go. A couple of years ago, we wrote about the NanoVelcro microfluidic device that effectively harvests CTCs from blood, but it suffered from the same problem and required specialized equipment and laborious effort to remove the captured cells. Now the research team has developed a pretty simple release method so the cells can go under the microscope for analysis. As the name implies, the NanoVelcro chip has a hairy array of nanoscale wires, each with antibodies of proteins found in CTCs at the tips. As the blood passes by the wire hairs, the CTCs stick to them. In the process of figuring out how to detach the cells, the team discovered that by lowering the temperature of the environment around the hairs from body temperature to 4° Celsius, the cells pop off and can be collected in pure, undamaged form. If everything goes as planned, we may see CTC capture devices being utilized in clinical practice for early screening and monitoring of cancer post treatment. “With our new system, we can control the blood’s temperature — the way coffeehouses would with an espresso machine, to capture and then release the cancer cells in great purity, ” said Hsian-Rong Tseng, a professor of molecular and medical pharmacology at UCLA. “We combined the thermoresponsive system with downstream mutational analysis to successfully monitor the disease evolution of a lung cancer patient. This shows the translational value of our device in managing non–small-cell lung cancer with underlying mutations.”

The Wellness Wristbands

Inbody band

We as of late came back from an occupied trek to the 2015 International CES in Las Vegas. Obviously, wellness wearables were a hot item. From shoddy silicone Fitbit imitators to cutting edge arm ornaments with smartwatch abilities, everybody appeared to need a bit of this inexorably immersed business sector. In the unending ocean of CES wellness wristbands that we waded through in excess of four days, here are a couple of remarkable groups we saw. Just in time for CES, Fitbit announced that their Charge HR and Surge trackers would finally start shipping. While we made mention of Fitbit’s newest products last week, we were able to try them out on the show floor. We were especially intrigued by the Surge (the one on the right in the image), which features a touchscreen, heart rate sensor, GPS antenna, and more. All are contained in a water-resistant device that lasts seven days on a charge. From afar, the InBody Band looked like just another fitness bracelet. However, this tracker has a unique sensor on its face. Place two of your fingers on your opposite hand on the two silver electrodes, and the InBody Band quickly measures your body fat percentage. InBody, as a company, has been producing body composition scales used in clinics and homes for years, so we’re optimistic this will give a fairly accurate estimate of how much flab you have. The band will be available in March. Magellan may be best known for their GPS receivers, but they showed us their recently announced Echo Fit Smart Sports Watch. Like many fitness smartwatches, the Echo Fit has a display that can pair with your phone and show notifications and act as a remote. Magellan boasts that the Echo Fit has an industry-leading 8 month battery life on a single coin cell battery.

The Samsung’s Simband

Health 2.0 WinterTech meeting in San Francisco Last January 15,2015

 

 

Samsung’s simband

Over the recent years, we’ve seen Samsung gradually entering the digital wellbeing space with ultrasound gadgets, medicinal evaluation TV screens, and all the more as of late, its line of Gear and Gear Fit trackers. This previous week at the Health 2.0 Wintertech meeting in San Francisco, Samsung flaunted somewhat more about their arrangements for utilizing their innovation to enhance our wellbeing. We had the capacity catch a few photographs of the stage screen with a telephone cam to provide for you a thought of what we saw. On stage, Dr. Tejash Shah, Samsung’s Director of Strategy & Business Development, showed off the Simband, a wearable that is based on Samsung’s Gear watch design and contains various sensors to measure a user’s biometric data. Sounds like just another wearable fitness band, right? However, the Simband isn’t meant for consumers. In fact, it won’t be commercialized at all. Simband is meant to be a platform that will allow wearables companies to improve on their devices and data processing algorithms. Developers can use the Simband’s sensors to ensure that they are accurately collecting data, and then in turn use that data to make better apps and devices, somewhat like a “wearables development kit”. The benefit of this is that wearables companies can be confident that they are developing on Samsung’s comprehensive, more universal platform, and they are collecting data using Samsung’s highly accurate and robust sensors. Some of the sensors available on the Simband include an accelerometer, gyroscope, ECG, galvanic skin response sensor, multiple optical sensors to measure pulse/heart rate, and a skin surface thermometer, which is included in some medical gadgets as well and used by so many people such as the US comfort women. All the data that will be gathered by this wearable gadget can be transferred wirelessly via Bluetooth 4.0.

All-In-One Clinical Computer

Durabook P24

Clinical computers are still traditional PCs connected to separate monitors. All-in-one computers, like the Durabook P24 from GammaTech Computer Corporation reviewed here, combine a fully capable computer within the back of a large high resolution display and allow for easy transportation between rooms, take up less space, need fewer cords, and make life a little easier for clinicians that use them and tech support folks that maintain them. We spent a couple weeks using the Durabook P24, an all-in-one computer developed for clinical applications, and would like to share our findings about this interesting new product. The P24 certainly looks slick, having nothing but a curved white bezel surrounding its 24-inch high-definition touchscreen. Besides an embedded webcam near the top and a small proximity sensor near the bottom, the front is visually sterile and doesn’t have any buttons, lights, jacks, or anything else to distract the user. Conveniently, the same design principle prevents any splashes or spills from damaging ports and dirty hands from accidentally touching the power button. Instead, all the inputs are located on the back near the bottom of the computer and the power button with its accompanying blue status light resides on the left side of the screen. There’s also an SD card reader easily accessible near the power button. The screen is flush with the bezel, making the front completely flat and therefore easy on the eyes and more importantly easy to clean. Not having any edges means there’s no room for pathogens to make home and hiding from a disinfecting wipe for them is a losing proposition. There is a convenient handle in the back to carry the thing around if you need to move it between rooms. The rear leg is solid and has a pleasant feel when folding it in and out.
