Hurt Knees Need
Correct Timing

A

JACK WILLIAMS SPECIAL TO THE JEWISH NEWS

fter decades of sometimes
conflicting theories on the
application of ice to injured
knees, a sports-medicine
physician has made a chilling dis-
covery:
The optimal amount of time to
ice an inflamed knee — and prob-
ably other major joints also — is
25 minutes per session. No more,
no less.
The conclusion is based on a
study directed by Dr. Sherwin Ho .
at the University of Chicago and
published in a recent issue of the

American Journal of Sports Med-
icine.

Icing has long been recognized
as a means of damage control to
joints and ligaments inflamed
from trauma or excessive use. As
little as five minutes of icing can
produce positive results, but the
researchers discovered increasing
benefits with each five-minute in-
crement.
Go up to 30 minutes and you
many impair nerve function.
While the study was confined
to the knee, it could well apply to
other often-injured joints such as
the shoulder, ankle and elbow,
said Dr. Ho.
Dr. Ho's study was a follow-up
to research he conducted that con-
firmed something health profes-
sionals long suspected: Ice can
have a profound impact on the
bones of a joint, decreasing
swelling and the rate at which in-
flammation occurs.
Dr. Ho said his next task in this
research trilogy is to determine
how long the icing effect lasts.

"We know the anti-inflamma-
tory effects of aspirin or ibuprofen
last four to six hours," he said. `The
same may be true of the icing ef-
fect. A good time to repeat the ic-
ing is when swelling returns."
Ice can be applied as a frozen
or gel sports pack, as crushed ice
or cubes in a plastic or rubber
pack. Avoid applying ice directly
to the skin unless you massage
a joint, trying to address an iso-
lated, tender area.
Heat, on the other hand, should
not be applied for at least the first
48 hours or until the swelling has
gone. Heat, which increases blood
flow, can then be used to relieve
pain and loosen tight muscles and
ligaments.
"Compression in conjunction
with ice is most effective because
we're trying to limit bleeding," Dr.
Ho said. "Some of the Velcro ice
wraps have buttons to provide
compression."
Knee injuries in the making are
the bane of recreational athletes.
Even bicyclists can irritate this
vulnerable joint.
The following knee-saving tips
are provided by Bicycling Maga-
zine, which consulted a number
of sports-medicine specialists:
• Keep knees warm by cover-
ing them when temperatures are
below 65 while cycling.
• Increase total mileage no
more than 10 percent per week.
• Don't ride a fixed-gear bike
or grind up hills while seated.
• Avoid resistance exercises. ❑
