Cervical range of motion norms12/2/2023 ![]() ![]() A Mc Neymar’s, Fisher’s exact and a Pearson’s correlation test was used to draw comparisons. Angles used were neutral (0°), 25° and 45° for left and right. This was followed by cervical spine strength tests for flexion, extension, and lateral flexion. Cervical ROM was tested in flexion, extension, lateral flexion, and rotation. The Multi-Cervical Unit (MCU) was used to test the cervical range of motion as well as isometric neck strength in multi-plane patterns of movement for the players. A personal detail and injury screening questionnaire, and Neck Disability Index (NDI) questionnaire was completed prior to testing taking place. METHODS: A descriptive, cross-sectional study were a total of 139 male (mean age 20.42 ± 3.29 years) senior rugby players participated in this study. To determine sport-specific strength norms, for the cervical spine, for senior rugby players. To determine if there is a relationship between cervical muscle weakness and poor posture. To determine isometric neck strength of senior rugby players. ![]() To determine the cervical range of motion of senior rugby players. To determine the posture of senior rugby players. To determine the occurrence of cervical spine injuries amongst senior rugby players. This study also aimed to establish sport-specific norms for neck strength for this population, which has the potential to aid in return to sport clearance. It also aspired to identify whether weak neck musculature, limitation in cervical range of motion, and poor posture are associated with an increased risk for cervical spine injuries. The occurrence of these cervical spine injuries has the potential to have a major influence on the quality of life, of rugby players following injury as well as a potential loss of life.ĪIM: This study was aimed to identify the prevalence and frequency at which cervical spine injuries occurred within a South African rugby population. The association between cervical spine muscle weakness, range of motion, and an increased risk for cervical injuries needs to be established, particularly in a South African context, where injury incidence seems to be higher compared to global incidence. Alternate methods of impairment evaluation should be developed that are more specific for individuals with true functional impairment and that account for age-related differences in spinal motion.BACKGROUND: Rugby is one of the most popular sporting types around the world with a total amount 2.82 million players in 2015 and 3.2 million in 2016. Impairment may be overestimated by up to 38%. The current method of impairment determination based on spinal motion may not accurately reflect impairment in many patients. The level of impairment increased with age for cervical, lumbar, and total impairment percentages (p = 0.0001). Based on the AMA criteria, all of the normal subjects were noted to have some degree of impairment ranging from 2 to 38.5%, with a mean value of 10.8%. Ninety-five individual measurements of cervical and lumbar spine motion were performed on each of 81 healthy subjects by two examiners using the double-inclinometer method. The purpose of this investigation was to test the validity of this concept by determining spinal impairment in normal subjects using one of the more popular rating systems, the American Medical Association (AMA) Guides to the Evaluation of Permanent Impairment. The validity of using spinal motion as the primary variable for impairment ratings must be questioned because of the large spectrum of age-related changes in motion in a normal population. Spinal range of motion is a major determinant of impairment in many disability rating schedules used today. ![]()
