Effects of the height of shoe heels on muscle activation of cervical and lumbar spine in healthy women

Abstract

[Purpose] The purpose of this study was to investigate the effects of different height of high heels on muscle activation of the paraspinalis cervicis and erector spinae in healthy young women. [Subjects and Methods] Thirteen healthy women were recruited in this study. To examine the effects of different heights of heels on muscle activation, the paraspinalis cervicis (cervical spine) and erector spinae (lumbar spine) were measured at the time of heel strike and toe off during gait on three different conditions (barefoot, 4 cm high heels, and 10 cm high heels). There are no previous trials or reports that have evaluated this approach in patients with chronic neck pain. [Results] A significant increase in muscle activation of the paraspinalis cervicis and erector spinae at heel strike and toe off (except that of the paraspinalis cervicis at toe off in healthy subjects) was observed in the under 10 cm high heel condition as, compared to that with barefoot condition, in all the subjects. [Conclusion] The height of the high heels affects to the activation demand of the paraspinalis cervicis and erector spinae in patients with neck pain.
