Cervical proprioception plays a crucial role in posture and movement control. This study aimed to determine the relationships of cervical proprioception, cervical muscle strength and endurance with manual dexterity and hand strength in individuals with idiopathic Parkinson's disease (PD).
Twenty individuals with PD (mean age: 63.9 years) and 20 healthy individuals as a control group (mean age: 61.9 years) were recruited. Cervical joint position error (JPE), static endurance of neck muscles, activation of deep cervical flexor muscles (Craniocervical Flexion Test, CCFT), manual dexterity (Purdue Pegboard Test, PPT), cognitive and motor tasks of the PPT, finger tapping test (FTT), pinch strength, and grip strength were assessed.
Cervical JPE was significantly higher in individuals with PD than in controls (p < 0.05). The strength and endurance of the cervical muscles were significantly decreased in individuals with PD (p < 0.05). Cervical JPE measurements were negatively correlated with PPT, cognitive and motor tasks of the PPT in individuals with PD (all p < 0.05). The endurance of cervical flexor muscles was negatively correlated with PPT and cognitive PPT scores in the PD group (p < 0.05). In addition, a significant positive correlation was found between cervical flexor endurance and hand strength in the PD group (p < 0.05).
Cervical proprioception and the strength and endurance of cervical muscles decrease in individuals with PD compared to healthy individuals. Impairment of cervical proprioception appears to be associated with poorer upper extremity performance. Detailed evaluation of the cervical region in PD may help determine the factors affecting upper extremity function.
颈部本体感觉在姿势和运动控制中起着至关重要的作用。本研究旨在确定特发性帕金森病（PD）患者的颈部本体感觉、颈部肌肉力量和耐力与手部灵巧性和握力之间的关系。
招募了20名PD患者（平均年龄：63.9岁）和20名健康个体作为对照组（平均年龄：61.9岁）。评估了颈椎关节位置误差（JPE）、颈部肌肉的静态耐力、颈深屈肌的激活（颅颈屈曲试验，CCFT）、手部灵巧性（普渡钉板试验，PPT）、PPT的认知和运动任务、手指敲击试验（FTT）、捏力和握力。
PD患者的颈椎JPE显著高于对照组（p < 0.05）。PD患者的颈部肌肉力量和耐力显著下降（p < 0.05）。PD患者的颈椎JPE测量值与PPT、PPT的认知和运动任务呈负相关（均p < 0.05）。PD组颈屈肌的耐力与PPT和认知PPT评分呈负相关（p < 0.05）。此外，PD组颈屈肌耐力与握力之间存在显著正相关（p < 0.05）。
与健康个体相比，PD患者的颈部本体感觉以及颈部肌肉的力量和耐力下降。颈部本体感觉受损似乎与上肢功能较差有关。对PD患者颈部区域进行详细评估可能有助于确定影响上肢功能的因素。
