 Conclusion
Background
 There are several modalities available for the
objective evaluation of functional exercise capacity.
 The most popular clinical exercise tests in order of
increasing complexity are:
stair climbing
6MWT
shuttle-walk test
cardiac stress test (e.g., Bruce
protocol)
Assessment of functional capacity has traditionally
been done by merely asking patients the following:
“How many flights of stairs can you climb or how
many blocks can you walk?”
“The 6MWT is easy to administer, better tolerated, and
more reflective of activities of daily living than the
other walk tests”
The self-paced 6MWT assess:
Submaximal level of functional
capacity.
The 6MWT requires:
100-ft hallway
 This test measures:
distance that a patient can quickly walk on a
flat, hard surface in a period of 6 minutes
(the 6MWD)

CONTRAINDICATIONS
Absolute contraindications
 unstable angina during the previous month and
myocardial infarction during the previous month.
Relative contraindications
 resting heart rate of more than 120
Systolic blood pressure of more than 180 mm Hg,
and a diastolic blood pressure of more than 100
mm Hg.
SAFETY ISSUES
1. Testing should be performed in a location where
a rapid, appropriate response to an emergency is
possible.
2. Supplies that must be available include oxygen,
sublingual nitroglycerine, aspirin, and albuterol
(metered dose inhaler or nebulizer). A telephone or
other means should be in place to enable a call for
help.
3. The technician should be certified in
cardiopulmonary resuscitation with a minimum of
Basic Life Support by an American Health
Association–approved cardiopulmonary
resuscitation course.
4. Physicians are not required to be present during all
tests.
5. If a patient is on chronic oxygen therapy, oxygen
should be given at their standard rate or as directed
by a physician or a protocol.
Reasons for immediately stopping a 6MWT include the
following
(1) chest pain
(2) intolerable dyspnea
(3) leg cramps
(4) Staggering
(5) Diaphoresis
(6) pale or ashen appearance.
Location
 The 6MWT should be performed indoors, along a
long, flat, straight, enclosed corridor with a hard
surface that is seldom traveled.
 The walking course must be 30 m in length. A 100-ft
hallway is, therefore, required. The length of the
corridor should be marked every 3 m.
 The turnaround points should be marked with a cone
(such as an orange traffic cone).
REQUIRED EQUIPMENT
1. Countdown timer (or stopwatch)
2. Mechanical lap counter
3. Two small cones to mark the turnaround points
4. A chair that can be easily moved along the walking
course.
5. Worksheets on a clipboard .
6. A source of oxygen .
7. Sphygmomanometer.
8. Telephone.
9. Automated electronic defibrillator
PATIENT PREPARATION
1. Comfortable clothing should be worn.
2 Appropriate shoes for walking should be worn.
3. Patients should use their usual walking aids during
the test (cane, walker, etc.).
4.The patient’s usual medical regimen should be
continued.
5. A light meal is acceptable before early morning or
early afternoon tests.
6. Patients should not have exercised vigorously within
2 hours of beginning the test.
MEASUREMENTS
1. Repeat testing should be performed about the same
time of day to minimize intraday variability.
2. A “warm-up” period before the test should not be
performed.
3. The patient should sit at rest in a chair, located
near the starting position, for at least 10 minutes
before the test starts.
4.During this time, check for contraindications,
measure pulse and blood pressure, and make sure
that clothing and shoes are appropriate. Compete the
first portion of the worksheet
5. Have the patient stand and rate their baseline
dyspnea and overall fatigue using the Borg scale .
6. Set the lap counter to zero and the timer to 6
minutes. Assemble all necessary equipment (lap
counter, timer, clipboard, Borg Scale, worksheet)
and move to the starting point.
Instruction to patient
“The object of this test is to walk as far as possible for
6 minutes. You will walk back and forth in this
hallway. Six minutes is a long time to walk, so you
will be exerting yourself. You will probably get out of
breath or become exhausted. You are permitted to
slow down, to stop, and to rest as necessary. You may
lean against the wall while resting, but resume
walking as soon as you are able.
 You will be walking back and forth around the cones.
You should pivot briskly around the cones and
continue back the other way without hesitation. Now
I’m going to show you. Please watch the way I turn
without hesitation.”
 Demonstrate by walking one lap yourself. Walk and
pivot around a cone briskly. “Are you ready to do
that? I am going to use this counter to keep track of
the number of laps you complete. I will click it each
time you turn around at this starting line. Remember
that the object is to walk AS FAR AS POSSIBLE for 6
minutes, but don’t run or jog. Start now, or whenever
you are ready.”
 Do not walk with the patient. As soon as the patient
starts to walk, start the timer.
 Mark the lap on the worksheet
 After the first minute, tell the patient the following
(in even tones): “You are doing well,You have 5
minutes to go.”
10. Post-test: Record the post walk Borg dyspnea and
fatigue levels
11. If using a pulse oximeter, measure SpO2 and pulse
rate from the oximeter and then remove the sensor.
12. Record the number of laps from the counter (or
tick marks on the worksheet).
13. Record the additional distance covered (the
number of meters in the final partial lap). Calculate
the total distance walked, rounding to the nearest
meter, and record it on the worksheet.
14. Congratulate the patient on good effort and offer a
drink of water.
Conclusion
 The 6MWT is a useful measure of functional capacity
targeted at people with at least moderately severe
impairment. The test has been widely used for
preoperative and postoperative evaluation and for
measuring the response to therapeutic interventions
for pulmonary and cardiac disease.
