自動車運転者とオートバイ運転者の頸部固有受容感覚と機能の比較分析および相関：横断研究

Neck proprioception and function are essential for individuals engaged in car and motorcycle driving. The comparison and correlation between these factors can vary significantly between car and motorcycle drivers, impacting their driving safety and comfort. The objective of this study was to investigate and compare the correlation between neck proprioception and neck function in individuals who frequently drive cars and motorcycles.

A cohort of 600 regular drivers (300 car and 300 motorcycle drivers) was recruited. Neck proprioception was measured using the Cervical Joint Position Error (CJPE) test, assessing right and left cervical rotation. Neck function was assessed using the Neck Disability Index (NDI). Descriptive statistics, correlation coefficients, and multiple linear regression models were applied for data analysis.

Car drivers demonstrated significantly poorer neck proprioception, indicated by higher CJPE scores (mean = 4.2 for right rotation, 4.1 for left rotation) compared to motorcycle drivers (mean = 3.1 for right rotation, 2.9 for left rotation, p < 0.001). Additionally, car drivers exhibited greater neck disability as shown by higher NDI scores (mean = 12.4) compared to motorcycle drivers (mean = 9.1, p < 0.001). There was a significant positive correlation between CJPE and NDI scores (r = 0.55, p < 0.001).

The findings indicate that car driving is associated with poorer neck proprioception and higher neck disability compared to motorcycle driving. Notably, driving type, age, and driving duration significantly influenced neck proprioception and function. The results highlight the potential importance of proprioceptive training interventions to enhance neck function, particularly for older car drivers and those with prolonged driving experience.
