Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Cervical Joint Position Sense (Head Relocation Error): Participants attempt to reposition their head to a perceived neutral position after flexion, extension, and rotation movements. The software records the deviation in pixels between actual and perceived head positions. Six trials per movement direction will be performed, with retesting after one hour.
Cervical Movement Sense - Patterned Tracking: Participants trace on-screen shapes (e.g., F8, ZZ) with their nose tip to evaluate movement accuracy. The total deviation from the ideal path in pixels will be measured. One practice trial and recorded attempts will be conducted, with retesting after one hour.
Cervical Movement Sense - Target Tracking: Participants follow a moving on-screen target with their nose tip. Tracking accuracy and time spent inside the target will be recorded. Three trials will be performed, with retesting after one week.
Sensorimotor Control Assessment: Participants align their head with randomly appearing visual targets for one minute. Performance will be evaluated based on the number of correct alignments and response accuracy. Three trials will be conducted, with retesting after one hour.
All data will be anonymized and analyzed for reliability using Intraclass Correlation Coefficient (ICC), Standard Error of Measurement (SEM), and Minimal Detectable Change (MDC). This non-invasive, computer-based methodology aims to provide a reliable and low-cost approach to assessing cervical joint position sense, movement perception, and sensorimotor control, contributing to future clinical and research applications.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Healthy Volunteer Cohort
A single cohort of 74 healthy adult volunteers will undergo an observational test-retest reliability study of four cervical proprioception assessments using computer-vision tracking. No medical interventions will be administered.
Two distinct assessment protocols control for learning effects and follow literature-based retest intervals:
Protocol A (n=37): Cervical Movement Sense Target Tracking at baseline and again after one week to assess longer-term reliability.
Protocol B (n=37): Head Relocation Test in 32 participants at baseline and again after one hour. Cervical Movement Sense Patterned Tracking and Cervical Proprioceptive Function Test in all 37 participants at baseline and again after one hour to minimize short-term learning effects. Separate participant groups prevent cross-test learning, and retest intervals (1 hour vs. 1 week) align with prior studies.
No interventions assigned to this group
