Will COVID-19 Change the Typical PT Patient?

People usually see a physical therapist for pain or loss of function. Think of the person who has
back pain, the injured athlete or the person who’s had a stroke. They all want to improve how
they move and complete tasks. Now, there is good reason to wonder if physical therapists will
start seeing more people who are not in pain or having difficulty moving. Why would these
people come to a PT? To improve their overall health and wellness.


There is strong evidence suggesting that movement is a valuable predictor of future health
and resilience against disease. Physical therapists are movement specialists, so taking
advantage of their expertise makes sense if your goal is to become healthier and live longer.
Here are some examples of the power of movement when it comes to predicting future health:


Gait Velocity

Gait velocity is how fast you walk. Studies have shown that if your typical walking speed is over
1 m/s or 3.3 ft/s, you’re likely able to complete typical daily activities independently. You’re also
less likely to be hospitalized and less likely to have adverse events like falls.


If you’d like to test yourself, measure out a straight, flat course to walk between 10′ and 30′ long.
You’ll also need 5′ or so at the beginning and the end for acceleration and deceleration. Walk
the course at your typical speed and divide the length of the course by how long it took you to
walk it (distance/time). That’s your gait velocity.


Get On and Off the Floor

A series of studies suggest that if you can go from standing to sitting on the floor and back to
standing without using your hands, you’re a lot less likely to die than someone who can’t. It’s
called the sitting-rising test. Here’s how it works:


You start standing, and without support you sit down on the floor, then stand back up. You start
with a score of 10. Every time you put a hand, knee, forearm or the side of your leg on the floor
you lose 1 point. Putting a hand on your knee or thigh to help also costs a point. In a sample of
over 2,000 people, they found that scoring less than 8 points made you twice as likely to die in
the next 6 years when compared to people who scored higher. Score 3 or less and you’re 5
times more likely to die in the same period. Overall, each point in the test is worth a 21%
decrease in mortality from all causes.


Notice that both gait velocity and the sitting-rising test aren’t specific to any one thing. The risk
of hospitalization in the gait velocity studies was hospitalization for any reason. Death in the
sitting-rising studies was death from anything. So while we know that exercise and healthy
lifestyle reduce your risk of specific diseases like heart disease or diabetes, it appears that
being able to move may provide much more wide ranging protection than we previously thought.

Do You Know Your Movement Vital Signs?

Most people think of heart rate or blood pressure when they think of vital signs. It is common to
use numbers to quantify health and risk of disease. The American Heart Association
encourages people to “know their numbers” referring to blood pressure, blood cholesterol, blood
glucose, and weight. However, research is now showing the importance of moving properly for
health. Let’s take a look at some of the numbers you can use to quantify your movement health:

Walking Speed

Walking speed has been called the “sixth vital sign” in medical literature recently. It is easy to
measure, and takes into account strength, balance, coordination, confidence, cardiovascular
fitness, tolerance to activity, and a whole host of other factors. It has also been shown to be
predictive of future hospitalizations, functional decline, and overall mortality. Normal walking
speed is considered to be 1.2 to 1.4 meters per second.

Push Ups

Push ups are popular to build strength, but a recent study found that they can show us a lot
about your heart too. Researchers found that men who could do 40 or more consecutive push
ups were at a 96% lower risk for cardiovascular disease than were men who could do less than
10. The push up test was also more useful in predicting future cardiovascular disease than
aerobic capacity measured on a treadmill.

Grip Strength

Hand grip strength has been shown to be strongly correlated with health. The stronger your
hand grip is, the less likely you are to suffer from cardiovascular disease, respiratory disease,
COPD, and all types of cancer. In the study, muscle weakness was defined as grip strength <26
kg for men and <16 kg for women. Grip strength below these numbers was highly correlated
with an increase in disease.

Standing From the Floor

If you can’t easily get down on the floor and back up your health might be in trouble, according
to a study that looked at more than 2,000 people. The study asked people to go from standing
to sitting on the floor and back up with as little support as needed. They found that if you need to
use more than one hand to get up and down from the floor that you were 2 to 5 times more
likely to die in the next 7 years than someone who can do it with just one hand, or even better,
no hands at all.

Moving well is obviously important to overall health and longer life. These tests can give a
snapshot of how you’re doing. If you’re having trouble with any of them, considering seeing a
movement specialist – your physical therapist.
