Survey of neck range of motion using system with sensor-integrated based on photometry method and zero method on healthy volunteers

Objective: The study aimed to evaluate the accuracy and reliability and of the system with sensor-integrated based on photometry method (PMD-HAM system) compared with the Zero method using a goniometry when measuring the range of motion of the neck joints of healthy volunteers at the Ho Chi Minh City Hospital for Rehabilitation and Occupational Diseases. Method: Conducted over four months at the Hospital for Rehabilitation – Occupational Diseases, the research included 50 healthy volunteers (24 males, 26 females) with strict inclusion and exclusion criteria. Both conventional goniometry and the system with sensor-integrated based on photometry method were utilized to assess cervical range of motion (ROM) across six movements: flexion, extension, right lateral flexion, left lateral flexion, right rotation, and left rotation. Results: Results indicated no statistically significant differences between the measurements obtained using both methods (p > 0.05). These findings suggest that the system with sensor-integrated based on photometry method is a reliable and valid alternative to traditional measurement techniques for assessing cervical ROM. Conclusion: The implementation of this innovative method may enhance routine clinical assessments, promote accurate data collection in diverse settings. Future research will involve a more varied participant demographic and refined measurement apparatus to further validate the method’s efficacy.
