Abstract

Background:  Various types of cervical collars have being used to immobilize the cervical spine. There was no information regarding the effectiveness of Cervicothoracic collars (Minerva) on restriction of motions in cervical spine. Therefore, the purpose of this study was to evaluate the immobilization achieved follow the use of Minerva collar in cervical and Cervicothoracic spine. Methods: Twenty healthy subjects (10 females and 10 males) were recruited in the study with no history of pain, deformity and surgery in spine. A motion analysis system was used to record the motions of cervical, upper thoracic and cervicothoracic in flexion, extension, lateral bending and rotation with and without Minerva collar.Results: The motion restriction of the upper cervical spine obtained with Minerva collar varied between 86.32 and 90%. The range of flexion/extension of cervical and cervicothoracic parts decreased by 27.35 and 56.32%, respectively follow the use of Minerva collar. The flexion/ extension range of motion of this segment decreased by 77.85 and 63.25%, respectively between occiput and T12.Conclusion: The maximum restriction of motion with Minerva collar was achieved in cervical spine. Due to the efficiency of Minerva collar to restrict the motions of cervical, especially in the upper part.
