Dear List Members
Lately I have seen a number of patients with hyperextension of the knee
during gait. The HE has usually resulted from one of the following
conditions: CVA, TBI(tramatic brain injury) and incomplete spinal injury.
Most of these people do not have an associated footdrop or loss of D/F range.
Some are up to 15 Deg. of HE and do so with a great deal of force. Some of
these people are able to control thier HE if they concentrate and walk
slowly and are working on this with thier Physiotherapists(this control
usually goes out the window when they are in a hurry or not completely
focused - hence the need for an orthosis)
I have used a range of orthoses, determined usually by the amount of force
involved and how active the person is.
I have found the C.H.E.C.K by Camp particularly useful but it will break
if used by the forceful, active hyperextender!
This is my question:
What are you fitting for the active forceful hyperextenders? (OTS and Custom)
To date I have used Functional ACL type KO's with usually 10-20 deg. ext.
stops installed. These work reasonably well but do not always fully limit
HE and of course are not designed primarally for this task. There knee
joints will deteriorate relatively quickly I'm sure.
I look forward to your responses and will post a summary to the whole list.
