Hi there I am a new user to this great forum and have been reading interesting threads on casting and orthotic manufacture, mainly posting v's skives etc. I was wondering if anyone has any links to papers, or information for the blake inverted procedure? I am sure it is a simple technique and I understand the concept but just don't really know how to use - at the moment I use medial heel skives but don't invert the cast as Kevin Kirby suggests.

Re: Casting
many thanks Simon I searched the internet and couldn't find anything, I have the valmassey book but didn't think to look there, Doh!!! -
I used Blakes original publications going back to 1978? JAPMA I think...I'm sure Craig could tell you off the top of his head...there were two or three that gave me enough to start making them.....one written with a female co-author?.....dredging the bottom of a foggy memory here

Dr. Richard Blake did the CCPM Biomechanics Fellowship a few years before I did the Biomechanics Fellowship. I helped him make his inverted orthoses for him when he was first creating the technique (when I was a 3rd year podiatry student). The chapter in Valmassy's book is an excellent review Dr. Blake's technique. I also discuss the biomechanics of the Blake Inverted Orthosis in the chapter that Don Green and I did in DeValentine's book (Kirby KA, Green DR: Evaluation and Nonoperative Management of Pes Valgus, pp. 295-327, in DeValentine, S.(ed), Foot and Ankle Disorders in Children. Churchill-Livingstone, New York, 1992).
Here are the other Blake Inverted Orthosis Technique references for your reading pleasure:

Thats brilliant, thanks for your help!

hello,
reading Valmassy p 448 it says that a 25 degree inverted orthoses (Blake inverted) is standard practice, and that this orthotic can correct up to 5 degrees of rearfoot valgus-
1- can anyone tell me if an orthotic such as this is good for a child?
2 - does the plantar fascia not become irritated as a result of the contoured shape at the medial longitudinal arch; inversion, especially with very active children?
3 - does the altered coupling of the ankle/subtalar and knee cause any knee pain?
thanks -
1.Sometimes
2.If the shape is right, no
3.Sometimes.

Could you be so kind as to post a copy of this
Blake RL: Inverted functional orthoses. JAPMA, 76:275-276, 1986.
Its not available from JAPMA online

Here's a great paper that I think backs up the current thinking and research on the action of posted / inverted orthoses.
Effect of Inverted Orthoses on Lower-Extremity Mechanics in Runners
DORSEY S. WILLIAMS III1, IRENE MCCLAY DAVIS2,3, and STEPHEN P. BAITCH4
ACSM 2003 www.udel.edu/PT/davis/Inverted_orthoses_mechanics.pdf
My summary
Considering 3 conditions of - no orthoses, standard 4dgs root and blake inverted 15-25dgs. N=11
Using Vicon motion analysis and Bertec force plate kinetics and kinematics of lower limb and foot where characterised.
Mean eversion across all subjects show no change However individuals showed wide range of change in eversion RoM
Mean internal inversion moments very significantly and relatively reduced with greater inversion of orthosis. NB Mean internal eversion moment similarly increased. Mean Knee internal adduction moment reduced and knee internal abduction moment increased.
Mean Internal rotation of tibia relative to foot increased.
Concluded that even tho kinematic RoM was not changed the kinetics in terms of internal moments were and this would probably result in reduced stess and injury to tissues. NB There may be increased risk of trauma where the moments are increased.

JAPMA online also doesn't allow me access to that paper. I don't think I have it readily available but is rather buried somewhere in my 25+ years of collected papers. Maybe someone else has it?? -
Just for you.....went out into the garage this afternoon.....unpacked all my old JAPMA journals stacked in boxes at the side of the garage.....found the May 1986 issue.....scanned Blake's article....enjoy.:drinksAttached Files:

Prof Kevin
Brilliant :D

Here is another one of Rich Blake's early articles on foot orthoses. This was coauthored by Jane Denton, DPM. Jane currently practices in San Francisco with Rich and Ron Valmassy. She also did the Biomechanics Fellowship and was my Biomechanics Fellow during my 3rd year of podiatry school (Blake RL, Denton J: Functional foot orthoses for athletic injuries. JAPMA, 75:359-362,1985).Attached Files:

Hi,
Is there any way to access a copy of
Blake RL, Ferguson H: Foot orthosis for the severe flatfoot in sports. JAPMA, 81:549, 1991.
It is not on JAPMA
Thank you -
I am floundering how to use this forum to give answers about the Inverted Orthotic Technique. I still use the technique, as do thousands that I know. In 30 years I have learned alot about it, from prescribing to manufacturing, but it is hard to know where to start in such a forum as this. Any help you can give me, or any help in answering your questions I am excited about giving. Sincerely, Rich Blake

I'm glad to see you on this form. What an asset to other practitioners!

opps, forum!

I would suggest start commenting on treatment of various conditions when someone asks a question that you feel you want to spend the time answering. You may also post illustrations, photos, and You Tube videos on this forum which can greatly add to the usefulness of the postings. The discussions are quite sophisticated at times so I don't think you will need to "hold back" in your descriptions or in your terminology. If you have any problems with understanding how to navigate or post on Podiatry Arena, please e-mail me privately at kevinakirby@comcast.net.
Hey....here's a good memory for you....have you ever run more miles in a week than you did in the Border to Border Run?? -
trust Kevin to direct this forum :D

Being the inventor of the Blake Inverted Technique I would love some questions regarding the techique. In 30 years of use, the technique has been modified, explored, and practiced on tens of thousands of patients. Let me know if you have questions. Dr Rich Blake

I believe I recall reading in your chapter in Ron's book that chose the arch height in the finished device. I was wondering how you chose the arch height.
For those who don't know how an inverted cast is made: A platform is built on the positive cast that inverts the heel bisection. If you take a cast and invert it, this will make the medial arch of the device higher. Plaster filler is added to the arch and then shaped like how the arch would have been had the cast not been inverted.
Thanks in advance,
Eric -
Eric, Thank you for you question regarding determining the arch height of the Inverted Orthotic Technique. I have attached the link to my blog where I answered this as best I could. Let me know if there are any questions. Thank you so very much. Rich

Hi Rich,
We are currently discussing the midtarsal joint - http://www.podiatry-arena.com/podiatry-forum/showthread.php?t=54294 and the work of Nester et al. Does this new approach to thinking of the midatrsal joint axis change effect any of your views on how the Inverted Orthotic functions. -
We did a PodChatLive with Richard on the inverted orthotic technique
