The purpose of this study is to investigate the effect of flank exercise, using various supporting surfaces, on the distance between bottom peaks, cranio-vertebral angle(CVA), and rounded shoulder posture.
Thirty normal adults in their 20s from A city S University participate in the experiment. They are randomly divided into 2 groups: a stable ground plank exercise group (n=15) and an unstable ground plank exercise group (n=15). The experiment was carried out three times per week for four weeks. Measurement methods were to measure the CVA and the round shoulder in the right lying posture using a goniometer and Vernier calipers, respectively.
There was a significant difference (p <.05) between head and spine angle before and after exercise in the unstable surface group, but no significant difference between the stable and unstable surface groups. There was a significant difference in the round shoulder posture in the unstable surface group between pre and post exercise (p <.05), but there was no significant difference between the stable and unstable plank groups.
The plank exercise on an unstable support surface is suggested to be effective in correcting the round shoulder posture and CVA.
