Planarflexion; Responses

Thanks to all who responded.

Below is my original post followed by the responses, there were many
duplicate responses that are not posted.

I have a client who is a bowler and is requesting specific information about
prosthetic feet. He would like to know which foot has the greatest ROM in
platarflexion. He has a Bock single axis foot at present. He believes if he
had more platarflexion at the ankle and could get his foot flatter, sooner
and easier he would feel more stable and be able to generate more power
bowling. If you know the answer to this question or where I might find this
information I would appreciate your response. I will post a compilation of
the responses.

RESPONSES:

You might try the OWW S/A foot because there is a bumper in the front as
well that he might appreciate. You can get different durometer anterior and
posterior bumpers.
Then again, you might even try a College Park foot, because he may
appreciate the extra multiaxis movement, and of course those bumpers can be
tuned as well.
****************
I would look at the genesis II foot. It is supposed to have a greater ROM
than College Park. You could experiment with different bumpers to see what
works. Also look into the Athletic fund, ACA, or special Olympics, there
might be a bowler there he could talk to.

As a former PBA member this one seems second nature to me. I am assuming
that your bowler is right-handed and that his amputation is on the left side
(or if he is left-handed and the amputation is right). The key is to make
sure that dorsiflexion is limited during the slide. By the time ankle motion
comes into play the sliding foot should be in neutral in relation to tibia
with body-weight placed directly over the foot. With the foot in neutral the
bowler can create leverage as if pushing off of a wall. If the foot
dorsiflexes past neutral, leverage is lost. The ability for the foot to
plantarflex is irrelevant since the dynamics of the bowling approach are
different from normal gait. It may be difficult to convince your bowler,
however a standard dynamic foot with no ankle motion is probably the best
bet. The flexible keel will aid push-off and the foot will be stable
throughout the slide, consequently creating optimum leverage and power.

Contact Kyle Smith at Jim Smith Sales and ask about
the Genesis II foot. I have several very active folks
on it and they love it.

Try the THDLA (Tall Heavy Duty Large Adult ) DAS MARS (Dual Ankle Springs
Multi-Axial Rotation System). The tall unit allows for the most plantar
flexion along with rotation at the same time . It is used in combination
with whichever symes type foot you prefer or now is available in a
carbon keel version.

The Arthroglide ankle seems to add a significant range to whatever foot
you're using.

I'm not sure but you might look at the Talux by flex foot. It has alot
motion that a bowler might want.
