THANK YOU! I'm doing a study with 5 triathletes and whant to see the impact of two pairs of orthoses (1 neutral position 1 50%more correction) on the lower limb alignement and on the muscles activity while cycling. using dartfish and EMG.
Orthoses are made with cad-cam.
I was suppose to do my study on 15triathletes but for a budget and time question we will take only 5subjects and I was thinking of the validity of a study with only 5subjects.
It not really an issue of "validity" based on the true definition of validity. Its more an issue of generalisability of the results. With the sample size you have, then how generalisable will the results be to the population of triathletes? As Ian says, it really an issue of statistical power and sample size calculation.
