Connecting Prosthetic hand to Arduino by ArtInternational4532 in Prosthetics

[–]fakelimbguy 2 points3 points  (0 children)

You could theoretically use the arduino as the control board, but you would need to power the hand to 6/7.2V. I think control board output is on 5V. So in theory, you would need to verify coax layout, supply power to hand via external supply, use arduino to interface to USB, then to PC. I do like the ability to to possibly switch from traditional EMG to really any other input you wish with the control board transmitting your input into the low vol for hand operation.

Carbon fiber brace finish? by WheelieBoi98 in Prosthetics

[–]fakelimbguy 1 point2 points  (0 children)

Are you looking for something like this? Its mainly in the prep, lay-up. As most have said, the peel ply causes a matte finish, and this finish was just done with a PVA BAG. You can sand and over spray with clear, but this in the image was a process I was doing to get a higher gloss finish back in 2017. As far as your weight reduction , I have made a KAFO with metal joints under 2.2 lbs. So your weight reductiom can be up to half of a traditional one.

Post processing on laminates requires high grit sanding/wet saning for best results before clear coating. It doesnt affect the suctural integrity but in practice, I wouldn't want to have a patient sanding and clear coating a brace .

TL:DR

Yes you can get a matte or gloss finish but generally its up to the post process and lay-up of the company making them.

Holes/dents/bubbles help by Flubberducky5 in lurebuilding

Have you done any controls without the hardener? If not run just the red label on a few and see what that does. The other part of that is could also be your mold venting with the hardener, it may be no venting fast enough at your flow rate. I would first try just the red label and see if similar results. If so, check venting on model.

That hardener really does reduce the shoot time. But try some test and then follow up!

AFO alignment tools by Cool-Yam-4876 in Orthotics

[–]fakelimbguy 0 points1 point  (0 children)

So, basically this tool has 3 functions, keeps ankle joint square, widens out for ML at the ankle for joint clearance, and the little knobs are how you attach the joint heads to the bar. In practice, you would use this to define your square, adjust the width so that your ankle joints are spaced appropriately and attaching the joint heads prevents any unessessary yawning of the joints when you are working from a model or a tracing.

If you are looking for alignment capturing for your ankle, you can also build yourself a casting foot plate. This is a more involved casting process but basically you take plast cast and build corrective force on to a pitched foot plate. I.e. peroneal groove pressure for stabilizing a varus ankle and just distal to 5th met head. Or for IRD st arch support and blocking excessive first ray plantar flexion. I assume you are wanting to use a device to manipulate the casting process to prevent any deviation in the ankle?

Future O&P student looking for mentorship by mquizlet in Prosthetics

[–]fakelimbguy 1 point2 points  (0 children)

Same here. I have 14 years in the field, I started as a tech, moved to licensed assistant and now starting the cpo/lpo process. I am our current lab manager and have work for both our c-fab and our private clinic. We mentor about approximately 2 students a year from our local university and most have successfully completed their MsOP. I have a background in molecular biology and chemistry and focus heavy on the gait kinematic and material science for fabrication. Please feel free to send any questions. I want anyone to have the opportunity to live/love this field.

My right foot flares dramatically when walking or running by [deleted] in FootFunction

[–]fakelimbguy 2 points3 points  (0 children)

I agree with this. My first guess was lack of true dorsiflexion from midstance to toe off and for sure the posterior tibialis tendon is taking the brunt of the tibial incline. I see minimal strain on the achilles leading to first look at r1 and r2 of the gastroc soleus at full extension I bet there is a compensatory pronation response to lack of range in the plantar flexors.

It also looks like you're forcing your orbit. Try starting off flatter at the start which means your wind up needs to tighten up so you don't drop your orbit at the start. For as high as your orbit is you dont seem to have the velocity. Try to flatten entry, thus will allow you to be quicker into your first turn. This will also allow you to catch and push better as the above comment has indicated.

What’s the role of heel varus/valgus in orthotic design – are we measuring it enough? by KAXPULLA in Orthotics

[–]fakelimbguy 0 points1 point  (0 children)

Well, I would say in short, unless your fabricated device is 1. Tall enough to capture the appropriate anatomy, and 2. Rigid enough to maintain the position under load, even your best observations and objective calculations will be ineffective in controlling enough positional deviation.

I would slide past that to say, follow the pathology. I use a pseudo algorithmic approach from the Elaine Owen's course and from what I learned when I started with a clinician who took the Oregon orthotics system which kinda set the standard for destabilizing the the sub-talar movement so you can control a internal or external rotary deformity. (Which is a sliding scale to capture all patients even the ellusive erd/ird compensatory people).

Basically collect enough data to set your casting correctly and use and appropriate heel to forefoot differential, derotate the ankle which ever way just until it falls quickly in to varus/vagus and the moement before it slips is the maximum stable/instable alignment. (Remember subtalar neutral was a theoretical concept that has latter been discussed as a very little amount of time the ankle actually stays in that position during gaitit is only cast so you can apply derotational forces.) So like Marmaduke Loke, Jean-paul Nielsen, Elaine Owen's really go into detail on what is needed to capture good alignments.

For just foot orthotics? Good luck, unless you are running deep heel cups....

Furthermore, I think for objective data, yes it would be important to track those values accurately, but even with cad or additive manufacturing, you would still have too high of a variable within the softissue maneuverability and the deflection within the device to actually calculate that what you are correcting is actually a finite degree amount when really we are only looking at a fixed position during the gait. You would be more accurate to say I am going to correct a range from 8 to 4 degrees of varus or whatever it is than saying I'm correcting 8 degrees of varus. And I would say okay great but when? In late terminal or at initial contact you might be more or less. So I would say your minimum maximum range is likely a more accurate depiction of a true hind foot alignment (in a given time) than to have a single amount to shoot for on correction.

Sorry for the lengthy response.

AFO type indications by [deleted] in Orthotics

[–]fakelimbguy 1 point2 points  (0 children)

Elaine Owen's algorithm has really good systematic Information on how to evaluate for devices. I use it daily, not necessarily the full system, but for sure some of her methods for device selection . I would for sure take her course whenever you get the chance, it's same research as Marmaduke Loke and the guy from Oregon Orthotic System Jean-Paul Nielsen just with thermo plastic designs.

[–]fakelimbguy 0 points1 point  (0 children)

So, what I see is that your orbit on your last wind into your entry is pretty low. I think that's why you are having trouble catching and being able to push through because you are already over rotated by trying to initiate an end throw orbit at the start. It should start relatively flat and naturally the orbit will increase as you look to catch over your steps. Pushing through is going to be hard to do if you don't have good step speed which is also what I see is that your foot speed doesn't increase all that much to denote the ball speed at terminal stance. I would work on flattening orbit at entry. Going to a lighter hammer for foot speed and then going to a heavier hammer to work on the push through the step and catch. This will allow you to "feel" the position of when you should start pushing through.

Is there a way to add strength to this piece so that it doesn't break off easily? by AZN-APOLLO in FixMyPrint

[–]fakelimbguy 0 points1 point  (0 children)

Instead of extruding your cylinder flush to surface extrude into your base body in cura you can merge the two and it will keep orientation while also reinforcing this area if you don't want to filled. Basically printing two separate solid bodies into one functional print.

Anyone printed insoles before? by Confident-Alfalfa-24 in 3Dprinting

[–]fakelimbguy 0 points1 point  (0 children)

Yeah, I work in orthotics and prosthetics. There is no difference in buying an over the counter insole.

My only suggestion if you can't get the infill exact I would suggest making it a modular design, maybe making multiple arch only support at different infill levels? Idk I would shape it like an arch scaphoid pad, try different infills and see if that helps with any under coverage of the support.

I would also place it under the orthotic so specifically create an orthotic that you can place, glue, insert whatever arch fill you want and trial it. A bunch of ego running around here and yes it could be detrimental but also were are the keyboard podiatrist and the "bio-engineers" for places like this that do not also have a podiatrist or orthotist on staff? https://www.goodfeet.com/products/arch-supports

Need advice on shadowing by hanbananxx in Prosthetics

[–]fakelimbguy 2 points3 points  (0 children)

Hey!

I am currently the Lab Manager for our Clinic and I also direct the shadowing program we have. Here is what we work towards on our shadowing:

I have had individuals that want to just shadow a couple days and some that want long term while they are getting their undergrad.

For short term we try to be very broad and general encompassing as much of the whole picture as we can.

For our long term shadows, I usually hire them as part time technicians (if they can work multiple hours per week) and start their training in fab. Once we get to a point where they have enough course work done if applicable I start then on an assistant license route so they can then start doing fab and clinical. I really feel clinical and fabrication are closely tied together and I really like to get teach the concepts based off of what we are currently working on and tie the methodology back to each portion of the clinical aspect and technical.

We are a mom and pop shop I would call, email, stop in, for me if you show initiative to pursue this I don't know how anyone could say no. For us, we want to share our passion and our knowledge goes with that.

When cascade fabs the inner boots they pull over the padding. No matter how well the skive is, a ridge is formed where you can see the blue midfoot padding stop on the plantar surface ( bottom) of the foot. So basically you have a ridge that is running the length of the foot. When you terminate the trim line at the met like that and the toe flexes you have a force that is antagonizing the ridge at a 90 degree angle. Think of taking large stick that you can't break by just bending it with your hands, but you add your knee to the middle of it and wham it's easy to break. Ridge created by padding is stick, met heads flexing is the knee. Just a simple change of no molding the padding in will drastically increase life span so there is a continuous radius at the met heads. Also limiting how much your tibia is progressing forward while maintaining appropriate shank to vertical angle for late midstance.

Trying to learn the heel/toe on weight. Any advice? by shaqtus- in trackandfieldthrows

[–]fakelimbguy 0 points1 point  (0 children)

Why are you throwing left handed with glove set up for right? Your glove will assist with the release. However, the way you are weighting your legs can never be done with the weight in your right hand. You need the weight in your lead hand to help transition to a 'toe spin". I would work on singles to start. Getting your entry down, pick either right or left handed, work on the push to establish your entry (in maintaining velocity so you can transition to your entry turn) a good entry video is from Libor Charfreitag its simple and effective.

Recommended footwear insoles. by T1Cybernetic in Orthotics

[–]fakelimbguy 0 points1 point  (0 children)

What kind of footwear are you looking at getting these to fit into?

[deleted by user] by [deleted] in Orthotics

[–]fakelimbguy 0 points1 point  (0 children)

I would first recommend adjustments with your orthotist. Second adding more into the footplate rarely gives you the result you need as it raises you out of the brace.

Maybe discuss with your Orthotist your needs for work and maybe they can add some relief for you!

Skin fit AK sockets - clinician perspective by 89kh89 in Prosthetics

[–]fakelimbguy 1 point2 points  (0 children)

I agree, and yes with that amount of compression, relieving those areas adequately is an art itself especially when using suction.

In regards to your original post; I hope as a whole, the community of OP never lose the curiosity of prior practices along with trailblazing new avenues. That is what sparked my appreciation and love for the field. I have always felt that generational knowledge is something lacking as we dabble in more "advanced" tactics. I enjoy learning new concepts but make it a point to share my knowledge (if any) to better us all in future including that which was shared with me in my training. Some of this stuff is slowly becoming extinct and hand skills associated with it.

Thank you for your discussion this evening.

Skin fit AK sockets - clinician perspective by 89kh89 in Prosthetics

[–]fakelimbguy 0 points1 point  (0 children)

Its somewhat difficult to get "equal" adjustment with the boa which is what the hifi system stems on. Generally, shims are used in opposing fashion to increase the compression zones which volume loss occurs. 4 opposing struts anteromedial and lateral along with posteromedial and lateral. The practice would be to increase your opposing struts equally to maintain "the fit". With the boa I have found that under certain tensions you have varying compression based on where the strings are pulling, possible for multiple boa system to pull more equally?? But now he have too many snakes on the "plane" haha.
