They were selected purposefully and divided into three equal groups. The age range of the subjects was 18-25 years. To measure the electrical activity muscles of lower limbs, it was recorded using an electromyography device. Electromyography data were analyzed using biometric datalite program.

Therefore, using the appropriate post hoc test (LSD), it was shown that the activity of the gastrocnemius muscle in the post-test compared to the pre-test in the group of training in water (P<0.001; d=6.08) and theraband (P<0.001; d=3.66) had a significant increase of 24.03 and 16.46%, respectively. The activity of the semitendinosus muscle in the post-test compared to the pre-test in the water training group (P=0.041; d=4.98) and theraband (P=0.048; d=4.76) had a significant increase of 21.06 and 19.01%, respectively.</span></span><span style="font-family:"Times New Roman",serif"></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:15.0pt"><span calibri="" style="font-family:"><b><span new="" roman="" style="font-family:" times=""><span style="letter-spacing:-.2pt">Conclusion:</span></span></b><b> </b><span new="" roman="" style="font-family:" times=""><span style="letter-spacing:-.2pt">According to the present study, it seems that doing exercises in water and thera-band can play an effective role in improving the range of electrical activity of the muscles on lower limbs of people with pronated foot during walking.
