Sneak Peak: A lifEnabled dynamic energy storing prototype for children that have undergone a Dorsal Rhizotomy

Stay tuned for more info.  I believe this AFO can help the rehabilitation process for children that have undergone a Dorsal Rhizotomy.  I will be fitting this patient soon, I am excited to see what it can do.

For the curious types, the rod is not carbon fiber, this material has never been used before in the field of prosthetics and orthotics.  For the super curious, no I will not tell you what it is but I promise that I will share when I have more clinical information.

lifEnabled Dynamic AFO: One month later on an actual patient affected by MS

The lifEnabled Dynamic AFO has gone from concept stage to a working prototype that is in a clinical trial right now. The patient I have chose to wear the prototype has MS and is wearing the AFO’s bilaterally. Initial report are positive and she is enjoying the “spring” she gets from the AFO’s. She reports that the braces feel lighter than her previous pair and that she is walking faster with them. Standing up for her is a snap because she can load both AFO’s and they help her get up out of a chair. She is able to walk without assistance and come to a complete stop and stand, which she had not been previously able to do. She is excited about the AFO’s and would like to see other people affected by MS benefit from them. We will continue the trial as I want to make sure the dynamic rods will take the stresses long-term.

What is unique about this AFO? I believe it is the only Thermoplastic one-piece AFO with no hardware (screws, bolts, etc.) that is in development. The AFO can be fabricated without any special equipment and is cost effective to make, which means this technology will be available to a large patient population. We will see where this design goes, but I am excited to see the results so far.

Special Edition Guest Post: Jeff Boonstra, CP Reviews the BiOM PowerFoot from iWalk. Is it a game changer?

We had a fantastic experience the Power Foot Biom recently. One of my very high activity patients who has a short below the knee amputation was fit with a Demo of the Biom. After initial set-up he wore the prosthesis consistently for approximately 2 hours without taking it off or adjusting. Nick (patient) stated that the 4 ½ pound foot that he held in his hand, felt extremely lightweight, and he could not tell that there was any increase in weight from his previous prosthesis. Nick wear’s what is most likely to be the lightest BK prosthesis for K4 activity we could design. A lightweight carbon socket with the full length Freedom VS foot attached directly to the distal end of his socket. I would have put money on it, that Nick would have thought the Biom was heavy and he would have rejected it for weight.

However, I was wrong. He did not mention the weight once throughout the fitting process. As you can see in the videos Nick performed some extremely high level activities during his time wearing the foot. Now keep in mind as well, Nick has tried 7 different feet over the last 2 years and has chosen the Freedom VS as his number 1 choice. He loves the energy return and the smoothness of gait it provides. After wearing the Biom he was blown away when he had to put the carbon “passive” foot back on. His gait had completely changed and it took him about 30 minutes to get back into the gait pattern he had previously had.

The Power Foot Biom provides such a natural and “powered” response to the patient that it mimics their sound side limb almost identically. We were all very amazed at the amount of ground compliance the foot had, and the ability the foot had to power Nick up hills and ramps with the powered plantar-flexion.

In the end Nick did not want to give the foot back, as he felt that is was the smoothest, most comfortable thing he had ever felt. He also noted that the foot reduced the amount of forces and pressures he felt in his socket.

I cannot speak to battery life, but iWalk is telling us roughly 4 to 5 hours of walking before needing to switch the battery. The batteries are very easy to switch out, and in my opinion for what the foot offers would not be too great of an inconvenience to the patient. Overall the Power Foot Biom impressed us greatly. As an able bodied Prosthetist, we know that it is difficult sometimes to feel what our patients are feeling, or understand their frustrations. Sometimes it is very difficult to relate to what the patient is going through, and we learn something every day that makes us get better and better. This was one of those times where you just know things are right, and that the patient is completely satisfied with the fit and function of the device, and when we can offer a device that gives the patient that feeling it is the ultimate achievement.

Jeff took some video and I edited it down. Enjoy!

If anyone is in the South Dakota area and is interested in the BiOM I would urge you to talk to Jeff Boonstra, CP.

I personally have not fit one of these but if you are in the North Carolina area I would be happy to get you more information and possibly a demo, please contact me at brent@lifenabled.com .

Please Answer a Few Questions: Sneak Information! Kinetic Revolutions shares some new information on future options for the adjustable pylon

Kinetic Revolutions will be launching a shorter version of the adjustable pylon in October and a
pediatric version in late November.

Now for the questions, I would like to know:

Are you using it?
If so, how many have you fit?
Do you have any suggestions for improvements?
If not, why? (cost, length constraints, weight limit, other…)

Please either comment or email me brent@lifenabled.com with responses

Continued Sneak Peak of Coyote Design Lanyard Prototype and Above the Knee Prosthesis

Here is a picture of the Coyote Design Lanyard Prototype for a definitive socket. I like the new offset and angle adapter plate they offer. The plate can be used so only one lamination is necessary. I did fit the socket and the patient appreciated the ease of donning with the locking mechanism. She was able to tell how deep she was in the socket due to how many “clicks” she heard. I hope they end up releasing this lock.

Sneak Peak: Coyote Design Lanyard??? for Transfemoral Prosthetic Sockets

I got my hands on a prototype lanyard lock from Coyote Design. The lock is a little lower profile than their Airlock or Suction lock and now they have an offset plate with at 5 degrees of flexion built in. The test socket can be fabricated with the plate built in and then you can transfer your alignment to do a one shot lamination.
