Six_Minute_Walk_Distance v.1
The 6-Minute Walk Distance (6MWD) is a tool to quickly assess physical function and an important component of quality of life, as well as to reflect the capacity to undertake day-to-day activities.
To record the parameters for calculating the expected 6MWD.
6MWD is can be used in these several conditions: 1. to assess response to interventions in patients with moderate to severe heart or lung disease 2. to measure functional status in patients who are elderly, frail, arthritis, neuromuscular disorders, and/or otherwise unable to tolerate treadmill exercise tests. The formula for calculating the expected 6MWD is based on the patient gender, height, age, and weight. For male patients The expected 6MWD in meters = (7.57 × height in cm) – (5.02 × age) – (1.76 × weight in kg) – 309 Lower limit of normal = 6MWD - 153 For female patients: The expected 6MWD in meters = (2.11 × height in cm) – (2.29 × weight in kg) – (5.78 × age) + 667 Lower limit of normal = 6MWD - 139 The particular formula only applies for patients between 40 to 80 years of ages and for Caucasian ethnicity. The result might be less accurate in shorter patients, who have shorter strides.
Not to be used for assessment of patient with unstable angina or MI in the last 1 month.
