FEMALE ANNOUNCER:
From NIHSeniorHealth.gov, built with you in mind. MALE NARRATOR:
Here are some of the exericses that are part of
physical therapy following knee replacement. The exercises include
standing hip flexion, proprioceptive standing, stool walking,
stationary bicycle, leg press, knee extension,
and cool down. The purpose of the standing
hip flexion exercise is to strengthen the quadriceps and the hip flexor. Those are the muscles
on the front part of the thigh. When she’s out to the side, when the standing
hip abduction exercise is to strengthen
the hip abductors. And those muscles
are important for gait. When she’s standing
and extending her leg, which is a standing hip
extension exercise. So if she’s standing up,
kicking her leg, entire leg, behind her, it’s working
on the hip extensors. Proprioception means
position sense. It’s the body’s ability
to stand on one leg or keep its balance
without falling. So it’s really more or less
a correcting exercise. When you have surgery
on a joint, proprioception is lost. And what we try to do is work on training
that proprioception back. So when a person
now is on one leg or if they have to step off
of a curve or things like that, they’re able to keep
their balance without falling. When you’re sitting
on a chair and you’re putting your legs
in front of you, we call it stool walking. Stool, S-T-O-O-L. Stool walking. And its aim is to try to work
on strengthening the hamstrings as you’re going through it. It’s also going to promote
your knee bending. So we’re working on
when a person sort of digs in with their heels
and scoots forward, they actually use
their hamstrings to help propel them forward. And they also are increasing
their knee flexion at that time. Stationary bike
is an exercise that we use to help in the case of
our knee replacement patients. We try to use it to help
with range of motion first. So right now it takes anywhere
between 95 to 102 degrees or so to bend on the bike. So we try to use it to help
promote the knee bending first. When a person gets comfortable
with that motion, then we’ll try to work
on strength and endurance at that time. When you’re sitting down
in a chair, extending your knee, that exercise is called
a knee extension. Some people also call it
a quadricep extension, or a long arc
quadricep exercise. It involves having your knee starting at about 90 degrees and then extending
all the way to zero or being completely straight from a bent position. That’s an inverted
leg press machine. The machine –
the machine that involves a pushing up fashion
from an inverted position. And the ball in the middle was used to actually
help the person contract their quadricep muscles
at the same time that they’re pushing up, again, working on increasing
the strength of the muscles around the knee joint. Because we really stir up things
inside of a knee joint when we’re performing
physical therapy, most therapists will tend
to cool down a knee joint afterwards
with ice applications. The technique
that we use there is a system called
a crowd cuff system. And the technique of RICE,
Rest Ice Compression Elevation, is there’s an example of that used with a technique
we just did. So by using a coolant,
it’s just regular water, it fills the compartment up and it squeezes
their knee joint. So you’re having – with RICE,
you’re having rest because the person
is off of their body part. Ice because the water is cold
inside of there. The C part of that
is the compression. And the E would be
the elevation if you raise that body part up
above the level of their heart. So we’re trying to slow down
any of the swelling that may occur
from the exercises that we had that person do while they were experiencing
physical therapy. MALE ANNOUNCER:
