What is 2 minute walk test?
The 2-Minute Walk Test is an outcome measure that assesses endurance in static gait, or gait that is without obstacles or secondary tasks.
It allows insight into the patient’s endurance,gait speed, and potential for household or community ambulation.
How is this blog helpful to you??
This blog will tell you about the 2-Minute Walk Test, measure your patient with accuracy, and then discuss how a patient’sperformance can be used in a clinical setting.
How to prepare for the 2 Minute walk test?
Preparing for the 2-Minute Walk Test begins by finding a location.
Try to find open areas with minimal foot traffic and attempt to limit the number of turns required.
At best, a 50-foot walkway would reduce the impact of turning on a patient’s performance.
Which type of pathway can be used in this 2 Minute walk test?
A variety of other pathway types can alsobe used in place of straight-line walking, such as walking in an oval pattern or in a figure-8 pattern.
How to measure the distance in 2 Minute walk test?
We recommend using a measuring wheel to ensure that you have an accurate measure of distance.
However, it is common practice to use other methods of measurement.
Examples include known hallway or clinic lengths and counting standard ceiling or floor tiles.
While these can work to get a fair measureof distance, they are much more prone to error due to miscounting or guessing.
What about Assistance devices used during this test?
Assistive devices can be used for the test,but they should be kept consistent and documented from test to test.
If the patient requires physical assistance to walk, this test should not be performed.
What all things needs to kept at mind during 2 minute walk test?
To begin the test, instruct the patient bysaying, “Cover as much ground as possible in these two minutes.
Walk continuously but if you need to slowdown or stop, don’t be concerned.
The point of this is to feel as though youhave covered as much ground as possible in these two minutes.”
How to keep a check on distance covered?
Follow the patient with the measuring wheelor keep count of distance, ensuring that you take note of distances covered during any turns.
As applicable, try to avoid walking in frontof or immediately beside the patient as they may assume your gait speed.
At the end of the two minutes, have the patient stop and rest, and note the full distance covered.
The test result, expressed in feet or meters,can be used for comparison to normative data over time.
Data for This test?
There are published normal data for the 2-MinuteWalk Test for adults of most ages and for many pathologies.
As an example, a 67-year-old male patientperforms the test walking a total of 312 feet.
How to challenge this exercise and make the most out of it?
When we look at normative data, we see thatwe should expect about 600 feet for an individual of that age and gender.
Therefore, we can set a long-term goal forthe patient of reaching the expected 600 feet in two minutes.
With this test we also want to look at a veryimportant property of any outcome tool, the minimal detectable change, or the smallest detectable difference.
How is this test helpful?
This value can be used to determine if a truechange has occurred with the patient.
It enables us to make short term goals inthe patient’s progression, repeating the test throughout the plan of care.
Examples where this test is used ?
As an example, the minimal detectable changefor an individual following a knee replacement is 49.1 feet.
If we measured a patient after knee replacementand they exhibited an improvement of greater than 49.1 feet, we can be confident that a true improvement has occurred.
