This study aims to evaluate how accurate and reliable two wearable sensor systems (inertial measurement units or IMUs) and a goniometer are in measuring cervical spine (neck) motion. Healthy adult volunteers will be asked to perform simple head movements in different directions while being assessed using the devices. The goal is to compare how closely these tools agree with each other and how consistently they record motion across repeated tests. This information will help determine whether the sensors are suitable for use in clinical settings to assess neck movement in future patient populations.
