Well, give a read to this post to know 6-minute walk test formula for male and female, and all you need to know about 6 minute walk test (6MWT).
The 6 minute walk test (6MWT) is the test that measures a functional status or fitness. A six minute walk test was developed by the ‘American Thoracic Society’; this test was officially introduced in 2002 along with comprehensive guideline. A 6 min walk test is utilized as a simple measure of aerobic exercise capacity. After this test, your health care provider may or may not lead to doing more balanced measures of your heart and lung function. And, this 6 minutes walk test is great to monitor your response to treatments for lung, heart, and various health problems. Typically, this test utilized for individuals who are suffering from pulmonary hypertension, interstitial lung disease, pre-lung transplant evaluation or COPD. Additionally, you can utilize our most accurate 6-minute walk test calculator and know how much distance you have to cover within 6 minutes with concerning your age, gender, height, weight, and distance walked!
6-minute walk distance for male patients:
6MWD in meters = (7.57 × height in cm) – (5.02 × age) – (1.76 × weight in kg) – 309
To find Lower limit of normal in male patients:
Lower limit of normal = 6MWD – 153
6-minute walk distance for female patients:
6MWD in meters = (2.11 × height in cm) – (2.29 × weight in kg) – (5.78 × age) + 667
To find Lower limit of normal in female patients:
Lower limit of normal = 6MWD – 139
An increase in the distance walked referred to as the basic improvement in mobility. Resnik et al recommended in Amputee rehabilitation, post training a difference of maximum 45 minutes must be taken into account for the six minutes walk test (6MWT) to ensure the “real change” in the patient’s condition.
Only in few neuromuscular conditions like Spinal Muscular Atrophy, Duchenne/Becker muscular dystrophy, Charcot-Marie-Tooth disease, and Myasthenia Gravis, here the 6-minute walk test has been implemented for the assessment of those patients and even considered regularly to capture any changes that provides really valuable information corresponding to the natural history of these disorders.
Some optimistic studies account the 6MWT to identify patients with neuromuscular junction dysfunction. By dividing the 6 minute walk test into 6 different components where each minute consists of different data point, the researchers revealed that the 6MWT can identify and malfunctions in the neuromuscular junctions. Also, by simply comparing the distance covered in the first & the last minutes revealed that how much the fatigue has influenced the individual.
Here are the conditions where the 6-minute walk test can be utilized are given below:
Before starting 6MWT, you ought to read about the 6 minute walk test norms properly! Additionally, if you are prone to anyone of the above conditions, then enter the values in the designated field of the above 6 minute walk test calculator and discuss your result with your medical expert.
An online six minute walk test calculator that is quite useful for assessing the 6-minute walk test (6MWT) for the patient who prescribed (6mwt). The 6MWT is the test that helps Health care experts to assess disability in patients with chronic bronchitis. Simply, this 6mwt predicted distance calculator will calculates the predicted distance in meters and percent.
This calculator for six-minute walk test is packed with user-friendly interface through which one can easily determine his/her fitness criteria corresponding to 6 minute walk distance. All you need to stick to the given steps to assessing this test with this calculator:
Once you entered all the parameters for 6MWT, simply hit the calculate button, this 6mwt predicted distance calculator will generate:
The equipment needed to conduct the 6 minute walk distance is mentioned below:
Before stick, to the given instruction, you have to make a 6 minute walk test form on a laminated card and read them thoroughly to get efficient results.
You have to use the following standard and encouragements to get 6 minute walk test normal values:
The six minute walk test distance (6MWTD) is considerably correlated with age (r = -0.29), height (r = 0.393), weight (r = 0.08), and BMI (r = -0.17). However, remember that the values are differ from age to age as from 40-85 the average distance is 400-700m/3600sec. Generally, individuals who are suffering from injuries have reduced 6MWD.
No doubt, 6 minute walk test norms change significantly with people of different countries, height, age, gender, and body weight.
Well, there are three case studies and tests between people of different countries and age:
In UK or United Kingdom, only 33 makes performed 6MWT with aged 55 to 75 under the standard protocol. Other measurements include parameters like weight, leg length; forced expiratory volume in 1 s (FEV1), and exhaled carbon monoxide and physical activities such as regular walking.
The average 6 minute walk distance was 659±62 m (range 484–820 m). Males walked only 59±13 m further than females (P<0.001). And, weight (r=0.25, P<0.05), height (r=0.54, P<0.01), and FEV1 (r=0.48, P<0.001) were significantly correlated with 6MWD.
Ahead stepwise different other lapses showed height (R2=0.294) and FEV1 (R2 change=0.045) said to be independent predictors of 6 minute walk distance (P<0.05), enlightening 33.9% of the change.
In Switzerland, adolescents and children aging from 5 to 17 years performed 6 minute walk test. Right after a short examination of their health and physical activity parameters, the test was performed.
Once the 6-minute walk test between different models: height, age, and heart rate predicted the distance walked, the age was the most influenced element, which predicted that younger children had more walking distance.
From India 125 subjects suffering from chronic heart diseases with Anthropometric variables height, age, leg length, body mass and performed in a 30 meter corridor.
The 6 minute walk test distance (6MWTD) significantly correlated with age (r = -0.29), height (r = 0.393), weight (r = 0.08), and BMI (r = -0.17).
6MWD significantly correlated with age (r = -0.29), height (r = 0.393), weight (r = 0.08), and BMI (r = -0.17).
Well, the gender equations for Indian individuals were:
561.022 – (2.507 × age [years]) + (1.505 × weight [kg]) – (0.055 × height [cm]). R2 = 0.288.
30.325 – (0.809 × age [years]) – (2.074 × weight [kg]) + (4.235 × height [cm]). R2 = 0.272
Well, the equations have a large error estimate along with a low determination coefficient; also, it concludes the walking capacity of Indian individuals.
The following predictive equations for the 6MWT:
Typically, the 6MWT is used to identify the walking capacity of people when they’re suffering from respiratory diseases like coronary heart diseases, asthma and when they having problems in their knees and hip bones to administer a person’s perception of oxygen & dyspnea saturation in blood during exertion.
Remember that 6 minute walk test norms from healthy individuals are compared with those who are suffering from certain diseases. The 6MWT norms vary significantly from gender, age, leg length, height and different other parameters.
If the patient stops during the 6 minutes, simply:
The score of the 6MWT is said to be the distance a patient walks in 6 minutes. Even, there is no such an assumption, the patient take as many standing rests as they want, but here the timer should keep running and just notice/record the number of rests that taken and the total rest time. Also, the 6 Minute Walk Test Calculator by calculator-online allow you to calculate the 6 minute walk distance for the patient who prescribed this test.
All you need to describe the walking track to the patient and then give the patient the above-mentioned instruction for 6-minute walk distance test (6MWDT).
Multiple regression analysis is something that depicted the given equation for VO2max prediction:
VO2max prediction equation: VO2max (mL/kg/min) = 12.701 + (0.06 × 6 minute walk distance in meters) – (0.732 × body mass indexkg/m2) (R2 = 0.79, [SEE] or standard error of the estimate = 2.91 mL/kg/min, %SEE = 6.9%).
Recently, the ATS (American Thoracic Society) developed guidelines for the 6 minute walk test in clinical settings. In healthy subjects, the 6 minute walk distance ranges indicated from 400 to 700 meter, and the main predictor variables being age, gender, and height.
The 6-minute walk test assists to measures the distance that someone can walk quickly on a flat, hard surface in 6 minutes. The 6MWT simply reflects the person’s ability to perform daily physical activities. Remember that COPD affects everyone differently; lung functions and even exercise tolerance testing helps MEDICAL Experts and patients work together to create the best treatment plan.
The American Thoracic Society (ATS) guidelines for the (6MWT) suggest using of 30m or 100 foot walkway along with the length of the corridor marked every 3m. ATS 2002 studies revealed that turnaround points are to be marked by a cone.
94618: The Current Procedural Terminology (CPT) code 94618 Pulmonary stress testing (for instance, 6-minute walk test) that including measurement of heart, oximetry, and oxygen titration, when performed defines the general simple pulmonary stress test.
The 6-minute walk distance is provided with a measure of the integrated global response of multiple cardiopulmonary and musculoskeletal systems, which involved in the exercise. The six minute walk test provides you with the information corresponding to the functional capacity, response to therapy and prognosis across a wide range of chronic cardiopulmonary conditions.
Optimistic studies depicted that walking is a safe and significant form of exercise for nearly every person, including individuals who living with chronic obstructive pulmonary disease (COPD). Also, a regular walking routine can make it easier for individual with COPD to be more self-sufficient & even better able to tolerate exercise.
Typically, the clinician does not walk with the tester during the 6 minutes walk test to avoid setting the walking pace. So, it is immensely important to worn pulse oximeter continuously as with the ease of these levels to be recorded at every minute.
Sometime, the clinician may choose to walk with the tester throughout the 6MWT; in this case, the clinician should try to walk slightly behind the tester.
The results that you will get with this 6 minute walk test calculator is just an indication, even the authors make no claims on the accuracy of the obtained results, so before a move to the final step, you ought to consult with your health care providers!
