4 Metre Walk Test

Question 1

Objective

Answer 1

• The 4 Metre Walk Test is walking speed test that assesses for functional limitations and physical performance.
• Commonly used test due to its simplicity and high test-retest reliability.

Question 2

Intended Population

Answer 2

• Total knee arthroplasty
• Total hip replacement
• Geriatrics

Question 3

Method of Use - Equipment

Answer 3

• A clear and even walkway of 4M
• Measuring tool
• Stopwatch
• Chair (optional to allow the patient to rest on if needed)

Question 4

Method of Use - Set-Up

Answer 4

• Measure and mark a clear path of 4M
• Add a clear mark of 0M
• Add a clear mark at 4M

Question 5

Instructions

Answer 5

• Instruct your patient to stand with both feet behind the first mark (0M)
• Instruct the patient to walk at their normal pace.
• Begin timing through your stopwatch as soon as one foot strikes past the first mark.
• Stop timing as soon as one foot strikes past the final mark.
• You may repeat the test if needed to calculate the average.

Question 6

Interpreting the test’s results

Answer 6

• A normal value is approximately 3.57 seconds.
• Furthermore, walking speeds of less than 0.8 m/s have been associated with falls risk.
• Measure and mark a clear path of 4M
• Add a clear mark of 0M
• Add a clear mark at 4M

Question 7

Evidence

Answer 7

• There is strong evidence to support that the 4MWT has a high test re-test reliability.
• Furthermore, in patients undergoing lower extremity surgeries such as total knee and hip arthroplasty, the 4MWT showed excellent reliability.
