Current Trends of In-Home Medical Devices and Technology

| No Comments
Zack Craft, vice president of rehabilitation technology and complex care at Total Medical Solutions identifies some of the current trends of the in-home medical device industry:

  1. Improvements in Home Automation. Zack says we're seeing a trend towards improved home automation, including the use of voice recognition to control electronic devices in the home. Bluetooth technology enables patients to interact with computer systems, power chairs, mobile phones, land lines, light switches and air conditioning thermostats. Being able to control temperature in the home is especially important when dialysis or wound care equipment is running -- it produces extra heat. In addition, voice recognition and other technologies help patients move beds up and down and allow video conferencing to monitor the front door -- so patients can see who is at the front door without getting out of bed. 
  2. Products are becoming more portable. More portable devices means reduced transportation and delivery costs. For example, Zack has noticed a trend towards having patients fill their own oxygen tanks. 
  3. Devices are getting smaller, cost less. Zack sees devices getting smaller and easier to use. He points out that wound vacs are now as small as a Sony Walkman radio device. Smaller devices provide the patient increased mobility and make it easier for patients to use devices in the home. Because the devices are shrinking in size, costs are decreasing as well. 
Zack was recently quoted in Assembly Magazine's article Medical Device Assembly: There's No Place Like Home

Thought-Controlled Prosthetic Limb Systems: Coming Soon

In other quite interesting technology news, Johns Hopkins Applied Physics Lab has won a contract to test a thought-controlled Modular Prosthetic Limb (MPL) system. Read the full story Hopkins Applied Physics Lab to Test Thought-Controlled Prosthetic Limb System at Robotics Trends website.

The MPL design offers 22 degrees of motion, including independent motion of each finger, in a package that weighs the same as a natural limb (about nine pounds). The MPL is capable of "...unprecedented mechanical agility and is designed to respond to the user's thoughts." Within the year, the Johns Hopkins APL team expects to initiate testing with a high spinal cord injury patient. The test results are designed to help upper-limb amputees and spinal cord injury patients, as well as others who have lost the ability to use their natural limbs, to have as normal a life as possible, despite severe injuries or degenerative neurological disease.

New Gadget Alert: Robot Wheelchairs and Bionic Legs

| No Comments
Another exciting development in wheelchair technology as reported by MedGadget last week in their post Wheelchair on Autopilot Follows Bipedaled Humans. This new technology has been introduced by engineers at Saitama University's Human-Robot Interaction Center in Japan. They have created a wheelchair movement system that keeps the wheelchair next to a person wearing a radio beacon. It is reportedly smart enough to anticipate turns and determine whether or not it should move beside the companion, or follow behind, when moving through congested or tight areas. Commercial production should follow soon. 


And in other news, Rex the robotic exoskeleton aims to make wheelchairs obsolete! as Engadget.com reported last month. Click the link to read the full press release and watch some really cool videos of Rex.

This set of bionic legs is the product of seven years of development work by Rex Bionics and Dr. Richard Roxburgh, a neurologist in Auckland, New Zealand. The Rex exoskeleton can support the full weight of a person, and according to the company's press release, assists a person who usually uses a wheelchair, enabling them to stand, walk and go up and down steps and slopes. So, paraplegics can move around in a familiar bipedal fashion. A joystick and control pad allow for easy navigation and is simple enough for handicapped users to self transfer in and out. The company plans an international launch in 2011. Wow!

Sniff Powered Wheelchair - Help for Severely Disabled

| No Comments
MedGadget.com recently highlighted a unique nose-controlled wheelchair designed to help severely disabled individuals. It may enable people with severe disabilities to navigate wheelchairs and communicate with their loved ones. The technology that powers the chair? Sniffing -- inhaling and exhaling through the nose. Read Nose Controlled Wheelchair for Severely Disabled

Researchers at the Weizmann Institute of Science in Israel developed the nose sniff controlled wheelchair and say it has proven to be of practical use for certain severely disabled patients, especially those with what is called "locked-in" syndrome. Sniffing, since it often remains as the sole mechanism with any kind of precise control for the severely disabled, can also serve as a good tool for communication. 

According to a press release by Weizmann Institute of Science, the technology is easily mastered, allowing users to navigate a wheelchair around a complex path or play a computer game with about the same speed and accuracy of a mouse or joystick. After just fifteen minutes of practice, a patient who is paralyzed from the neck down managed to navigate a wheelchair through a complex route as well as a non-disabled volunteer. Users were also able to communicate with family members - something they hadn't been able to do for a very long time. Four participants are using a new writing system and there are plans to further develop and distribute the technology. 

More on sniffing and "locked-in" patients.

Americans with Disabilities Act Marks 20 Years This Week

| No Comments

Twenty years ago this week, President George H. W. Bush signed into law the Americans with Disabilities Act (ADA). Although the ADA legislation included sweeping reforms intended to improve the lives of Americans with disabilities, there is still much debate over the cost and litigation associated with it. The ADA laws regulate employment practices, federal and local programs, transportation, public accommodations and commercial facilities.

Statistics: The Census Bureau claims that 54 million people have a disability - that's almost 1 in 5 Americans. More than 15 million people 15 years or older currently use a wheelchair.

News, information and events regarding the Americans with Disabilities Act:

MV-1 Wheels Across America Tour - Debuts the first factory-built wheelchair accessible vehicle

Disabilities debate rages 20 years later - an article by CNN.com

ADA Anniversary - a website devoted to events and information about the 20th anniversary of ADA

Disability.gov - a website connecting the disability community to information and opportunities; includes an announcement by President Obama

Disability Ramping: Consider Aluminum Over Wood

| No Comments

Does your claimant need disability ramping installed to access their home? Having ramping or other home modifications installed for injured workers is a big responsibility. And costly. The next time you need to purchase or install ramping for a claimant, Cara Barde, President of Total Medical Solutions, encourages you to consider the benefits of aluminum over wood:

Aluminum Ramping:

  1. Maintenace Free
  2. Does not rust or decay (aluminum lasts for 100+ years)
  3. Easy assembly with minimum tools
  4. No building permit required
  5. Can easily be expanded, reconfigured or moved
  6. Aluminum ramping is an asset that can be reused, resold or rented
  7. Installed in less than an hour!
  8. No environmental impact

Wood Ramping:

  1. Requires regular maintenance
  2. Will rot or decay over time
  3. Must be installed by a contractor or carpenter (increases costs)
  4. Requires a building permit (increases costs and time)
  5. Reconfiguration must be made by demolition and reconstruction
  6. No resale value; could actually lower the value of the home
  7. Typical installation takes 2 to 3 days
  8. Could include dangerous chemicals or applied treatments

As you can see, there are many benifits to using aluminum vs. wood disability ramping. In addition to the benefits of using aluminum ramping as outlined above, when you purchase your ramping through Total Medical Solutions, you can:

  • "Bank" your aluminum ramping - when it is no longer being used by your claimant, the insurance carrier can reuse the ramping for future claimants for a substantial cost savings
  • Rent aluminum ramping for temporary needs
  • Reconfigure aluminum ramping sections to fit any home
  • Easily move aluminum ramping to a new home if your claimant moves
  • Rest assured that the aluminum ramping we sell is dependable, durable and American made

Zack Craft,  vice president of rehabilitation technology and complex care for Total Medical Solutions, encourages a standing feature integrated into a wheelchair base whenever possible for injured workers confined to a wheelchair. While these types of wheelchairs are more expensive on the front end, they provide for greatly improved mobility and enhanced wellness of the patient. Thus, they provide for much better outcomes over the life of the claim. 

Wheelchair Standing Defined.

Wheelchairs with built in standing features allow the patient to obtain a standing position without transferring from the wheelchair. Such wheelchairs incorporate a mechanical or electromechanical system manipulated with levers or controls that move the seat from horizontal to a vertical or anteriorly sloping position while maintaining verticality of the legrests and backrest, thus extending the hips and knee joints. A full vertical standing position is achieved directly from sitting, or through gradual angle changes from a laying position, or a combination of either of these positions. Most wheelchair standers allow for full or partial extension of the hip and knee joints, and full upright or partially tilted positions.

Benefits of standing include:

  • Improved functional reach to enable participation in ADLs (Activities of Daily Living)
  • Enhanced independence and productivity
  • Vital organ capacity is greatly improved
  • Reduced occurrence of urinary tract infections
  • Bone mineral density loss reduced or eliminated
  • Improved circulation; reduced swelling in extremeties
  • Reduced abnormal muscle tone and spasticity
  • Occurrence of pressure sores reduced
  • Diminished occurrence of skeletal deformities
  • Enhanced physiological well being

Additional benefits of standing wheelchairs include: reduced fatigue, ability for some male patients to use public urinals, a reduction in the need for attendant care, reduced transfers and reduced home modifications.

One of the chairs Zack recommends to patients is the Permobil C500 VS.

A Little Pink Goes A Long Way...

| No Comments

TMS, with the help of employees like Zack Craft, VP of Rehabilitation Technology and Complex Care, is making workers' compensation a more positive industry -- one claimant at a time.

TMS received a referral from a case manager to review a claimant's wheelchair and replace the leg rests. After a brief in home visit and discussion with the claimant, a single mother of three, Zack discovered a few interesting facts. First, her wheelchair was not the right size. It was too wide, too heavy and too tall. The claimant was currently undergoing therapy three times per week to correct left side abduction due to lack of sensation and paralysis. Zack noticed as he talked with the claimant that since the wheelchair was too wide, it caused her to lean to the left side just to rest her arm. Second, he observed that she had to lean hard to the left so she could reach the left wheel to propel herself. Zack realized these factors contributed to the claimant's increased discomfort and could potentially lead to longer-term complications.

After his initial evaluation, Zack recommended a smaller, lighter and more functional wheelchair that would correct the claimant's posture issues. His goal? Get the claimant sitting up straight, provide her with increased mobility, and reduce wear and tear on her shoulders. Zack knew that by correcting these issues with a better fitting wheelchair, the claimant would have less stress on her shoulder joints. She would not have to exert as much effort to propel and she would feel much better. These changes would also extend the life of her rotator cuffs and provide her independence down the road.

A couple of other facts Zack noted on the initial visit -- the claimant's children were not able to lift and load the wheelchair because the rear wheels did not remove. So, the wheelchair limited the family's ability to travel. Last but not least, he learned that the claimant's favorite color is pink. 

So, with no real effort or added expense, Zack ordered a PINK wheelchair. The new wheelchair is at least 20 lbs lighter than the old one. Plus, the rear wheels are removable, making it easier for the children to load in the family vehicle for traveling. TMS employees took it one step further by "decorating" and "dazzling" the wheelchair with all kinds of gems and stars on the frame, and even put the claimant's initials on the back upholstery of the wheelchair.

When Zack delivered the wheelchair, the claimant began to cry. The health aid started to cry, and then the 18 year old daughter began to cry. The claimant was thrilled beyond belief that she was getting something that would help increase and maintain her independence. She was overwhelmed that the TMS employees had put in extra time to decorate her chair, and that it was her favorite color!

Zack says, "I left the claimant's home that day feeling the best I have felt in a long time...in my job, in my career, and in this industry." Let's face it, in workers' comp you don't see many things that are uplifiting or inspirational. But Zack left the claimant's home knowing that he had improved the quality of someone's life. Thanks to Zack's expertise, the TMS philosophy and the heart and soul of the TMS staff, one person will have a better life because someone took the time to notice a few details.

Zack also notes that the case manager on the file deserves credit for taking the time to involve TMS in the first place, then for listening to his recommendations. It's a great thing when clients actually take the advice of their vendors! 

The bottom line? One person's quality of life is greatly improved. The long term costs on the claim are reduced significantly due the the fact that the claimant will not need additional therapy just to be able to sit in her chair. Plus, there are additional cost savings because future equipment and/or surgeries have been avoided. The price tag on making someone's day or week because you remembered their favorite color? PRICELESS!

Assistive Technology 101

| No Comments
Assistive technology helps people with disabilities perform functions that may otherwise be difficult, or even impossible. Assistive technology can include any of the following: mobility devices such as walkers or wheelchairs; computer hardware, software or peripherals that enable people with disabilities to access computers or other information technologies that help them perform daily operations, and therefore become more self sufficient. 

Examples of assistive technology include: specialty keyboards designed with large keys or a special mouse or joystick for people with limited hand function; voice-recognition software for people who have motor disabilities; or eye tracking devices for people who have no control or limited control over their hand movements. 

Microsoft provides a very succinct overview of the full array of assistive technologies available on the market today.
