A novel instrument to examine the cervical rangeofmotion of healthy Vietnamese adults

This study aimed to evaluate a novel measurement instrument for recording cervical spine range of motion (ROM) in healthy Vietnamese adults at the Ho Chi Minh City Hospital for Rehabilitation -Occupational Diseases.A cross-sectional study was conducted from November 2023 to May 2024, involving 480 healthy volunteers aged 18-59 years who met the inclusion criteria.Their cervical ROM was measured in six directions (flexion, extension, left-side bending, right-side bending, left rotation and right rotation) using novel measurement the instrument (ROMIX), with data analysed by age, gender, and measurement time.Statistically significant differences (p<0.05) in ROM were observed across age groups, indicating decreased ROM with increasing age.However, no significant differences (p>0.05) were found between genders or measurement times.Thus, the novel instrument provides reliable ROM outcomes, highlighting age-related declines in normative ROM without gender or temporal variations.
