Effect of a mask-type craniocervical brace on head posture during computer typing in individuals with forward head posture

Abstract

Introduction. Craniocervical braces decreased poor posture, but they were uncomfortable and difficult to wear. Thus, the purpose of this study was to (1) design a new forward head posture (FHP) brace that would be comfortable and aesthetically pleasing, (2) analyse the immediate effect of using a mask-type craniocervical brace, (3) analyse the time interval when FHP may become worse in individuals with FHP. Methods. The mask-type brace was made of very light flexible plastic with the use of a 3d printer. Uverall, 32 volunteers typed for 15 minutes with and without the brace. Photogrammetric analysis was applied to calculate forward head angle. A greater forward head angle indicates a less protracted head. Results. Wearing the brace for 15 minutes significantly increased the forward head angle as compared with when the brace was not worn. The forward head angle significantly decreased at 15 minutes compared with the status at 0 and 1 minutes. Conclusions. The use of the mask-type craniocervical brace is a viable option for preventing deterioration of FHP during typing activities that last for more than 15 minutes.
