Background: Balance in humans relies on the integration of somatosensory, visual, and vestibular sensory systems, which work together to compensate for deficits in any one system. Vestibular disorders arise from pathologies affecting the vestibular apparatus in the middle ear or the central nervous system. Common symptoms include nystagmus, vertigo, imbalance, nausea, and headache, significantly impacting quality of life and postural stability. Objective: To determine the association between cervical proprioception deficits and balance impairments among various vestibular dysfunctions, including benign paroxysmal positional vertigo (BPPV), Meniere’s disease, unilateral vestibular dysfunction, and bilateral vestibular dysfunction. Methods: This cross-sectional study included 71 participants selected through purposive sampling over a six-month period. Cervical proprioception was measured using the Cervical Joint Position Error Test (CJPET), while balance deficits were evaluated with the Berg Balance Scale (BBS). Participants were categorized into three risk levels based on BBS scores: low fall risk (51–56), moderate fall risk (40–50), and high fall risk (<40). Age, gender, and BMI data were recorded, and statistical analysis was conducted to identify correlations between cervical joint position errors in flexion, extension, and rotation with balance outcomes. Results: The mean age of participants was 37.36 ± 7.35 years. Males constituted 64.8% of the sample, while females accounted for 35.2%. Most participants (81.6%) had normal BMI, 9.9% were underweight, and 8.5% were overweight. Significant correlations were found between balance impairments and cervical joint position errors in flexion (p = 0.025) and extension (p = 0.039), but no significant correlations were observed for left (p = 0.590) or right (p = 0.421) rotational movements. Conclusion: Cervical proprioception deficits in flexion and extension movements are significantly associated with balance impairments in patients with vestibular dysfunctions, while rotational movements showed no significant relationship. These findings highlight the importance of targeting specific cervical movements in therapeutic interventions for balance disorders.
