The six minute walk test (6MWT) is a functional capacity test which is widely used, as 23 walking depicts a general activity in daily living. 1, 2 This test is also classified as a 24 Za = 2.58 (confidence of 99%) and standard deviation (s) of 0.2 m/s (based on a study 1 by Bohannon that comfortable gait speed for both genders age 20-50 years old ranges 2 between 0.094 -0.229 m/s, thus obtaining the highest value rounded up to 0.2 m/s); and 3 absolute accuracy expected (d) of 0.1 m/s. Acknowledging the cross sectional nature of 4 this study, no drop out was considered. This calculation then yielded a sample size of n 5 = {2.58 x 0.2/(0.1)} 2 = 26.6 = 27 (rounded up). 6 7 This study then attempted to present each gender separately, but the gender 8 classification will not be compared for agreement. Therefore based on the sample size 9 calculation, this study gathered double of the initial calculation accounting for each 10 genders, summed up into 60 subjects. Sample size calculation for both genders are 11 considered the same due to identical standard deviation (s) and absolute accuracy (d) 12
values. Gait speed obtained from 4MGS were seen to be in agreement with the speed of 6MWT 1 performance. Additionally the 4MGS has a shorter test duration and requires a much 2 shorter track as compared to 6MWT. Both of these qualities are valuable during the 3 pandemic era, as the 4MGS would be highly applicable in the telemedicine setting. This 4 study had also shown that both 4MGS track, namely the six and eight meter, have 5 achieved good agreement to the 6MWT.
