Hi, my name is Eric Sampson, and I wanted to spend a few minutes talking about some
exercises to try to avoid in the presence of knee pain. Now obviously, there's a lot
different kind of problems, different pathology's, injuries, ligament tears, miniscule tears,
tendonitises, but in general there are a few things to worry about, if you are experiencing
some acute pain or in the presence of an episode of acute pain.
The first one I want to talk about is something that gets done way to often in your gym, as
well as at home and it's a simple leg extension exercise. So the exercise when you have your
leg straight, from a bent to straight position like this, is a very common thing that we
do in the clinic.
But in the presence of pain and also in the presence of an ankle weight, which is commonly
what we're going to use, or a machine where we have some weights attached to the machine
is a lot of joint compression, from this angle to about this angle, so the actual angle is
about 90 degrees to about 60 degrees.
This is something that we need to try to avoid and it ends up causing more harm than good
on the tendon that's trying to do lift and can lead to further problems. In the presence
of a weight, this might actually be a little bit more harmful. I would recommend the patient
start the exercise from an angle here and just coming straight up, rather than coming
from that lower angle, which they can cause a lot more damage than good.
