NCT07117292
Brief Summary:
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.
Detailed Description:
This interventional validation study will assess the concurrent validity and test-retest reliability of two inertial measurement unit (IMU) systems (Xsens DOT and Trigno Avanti) and a universal goniometer in measuring multi-planar cervical motion. A within-subject design will be used, with participants performing standardized active cervical range of motion (AROM) tasks in flexion, extension, lateral flexion, and rotation. All measurements will be conducted in a biomechanics lab setting under controlled conditions.
Each participant will undergo three testing sessions:
Familiarization session (optional)
Test session 1
Test session 2
Primary outcomes will include:
Peak angular displacement in each movement plane
Inter-device agreement (validity)
Intra-device test-retest consistency (reliability)
Sensor placement will follow anatomical landmarks based on previous biomechanical research. The IMUs and goniometer will be used simultaneously to compare measurements. Data analysis will involve intraclass correlation coefficients (ICC), standard error of measurement (SEM), and Bland-Altman plots for agreement analysis.
The study will recruit 20-30 healthy adults aged 18-40 with no current or past neck injury. The results will inform future clinical applications of wearable sensors in cervical spine assessment, particularly for populations with neck pain or neuromusculoskeletal disorders.
Ethical approval has been granted by the Cyprus National Bioethics Committee (Approval: ΕΕΒΚ ΕΠ 2025.01.231), and all participants will provide written informed consent.
