BACKGROUND: Cervical proprioception and muscle endurance are essential for maintaining cervical functional joint stability. Proprioception and muscle endurance may be impaired in those with general joint hypermobility (GJH). Examining these aspects is crucial. This study's aims are to (1) compare the cervical joint position error (JPE) and muscle endurance holding capacities in GJH individuals with and without non-specific neck pain (NSNP) (2) to assess the relationship between hypermobility Beighton scores, cervical JPE's, and muscle endurance in GJH individuals with and without NSNP. METHODS: In this cross-sectional comparative study, 33 GJH participants with NSNP (mean age 21.7 ± 1.8 years) and 35 asymptomatic participants GJH (mean age 22.42 ± 1.7 years) participated. Beighton's score of ≥4 of 9 tests was used as criteria to diagnose GJH. Cervical JPEs were estimated in degrees using a cervical range of motion device, and muscle endurance (flexor and extensor) were estimated in seconds using a stopwatch. RESULTS: GJH participants with NSNP showed significantly larger cervical JPEs ( < 0.001) and decreased muscle endurance holding times ( < 0.001) compared to asymptomatic participants. Beighton hypermobility scores showed a significant moderate positive correlation with cervical JPEs (flexion: = 0.43, = 0.013), left rotation: = 0.47, = 0.005, right rotation: = 0.57, = 0.001) in NSNP individuals. Also, Beighton hypermobility scores showed a moderate negative correlation with muscle endurance in NSNP (flexor muscles: = -0.40, = 0.020, extensor muscles: = -0.41, = 0.020, and asymptomatic individuals (flexor muscles: -0.34, = 0.045, extensor muscles: = -0.45, = 0.007). CONCLUSION: GJH individuals with NSNP showed increased cervical JPEs and reduced muscle endurance compared to asymptomatic. Individuals with GJH with higher Beighton scores demonstrated increased cervical JPEs and reduced neck muscle endurance holding ability. In clinical practice, therapists should be aware of these findings, incorporate proprioceptive and muscle endurance assessments, and formulate rehabilitation strategies for NSNP individuals with GJM.
背景：颈椎本体感觉和肌肉耐力对于维持颈椎功能关节稳定性至关重要。在全身性关节过度活动（GJH）患者中，本体感觉和肌肉耐力可能会受损。检查这些方面非常重要。本研究的目的是：（1）比较 GJH 个体中有无非特异性颈部疼痛（NSNP）的颈椎关节位置误差（JPE）和肌肉耐力保持能力；（2）评估 GJH 个体中有无 NSNP 的 Beighton 过度活动评分、颈椎 JPE 和肌肉耐力之间的关系。
方法：在这项横断面对比研究中，33 名 GJH 伴有 NSNP 的患者（平均年龄 21.7 ± 1.8 岁）和 35 名无症状 GJH 参与者（平均年龄 22.42 ± 1.7 岁）参与了研究。Beighton 评分≥9 项测试中的 4 项被用作诊断 GJH 的标准。使用颈椎活动范围设备评估颈椎 JPE，使用秒表评估肌肉耐力（屈肌和伸肌）。
结果：与无症状参与者相比，GJH 伴有 NSNP 的患者的颈椎 JPE 明显更大（<0.001），肌肉耐力保持时间明显缩短（<0.001）。Beighton 过度活动评分与 NSNP 个体的颈椎 JPE（屈曲： = 0.43， = 0.013）、左侧旋转（ = 0.47， = 0.005）和右侧旋转（ = 0.57， = 0.001）呈显著中度正相关。此外，Beighton 过度活动评分与 NSNP 个体的肌肉耐力呈中度负相关（屈肌： = -0.40， = 0.020，伸肌： = -0.41， = 0.020）和无症状个体（屈肌：-0.34， = 0.045，伸肌： = -0.45， = 0.007）。
结论：与无症状参与者相比，伴有 NSNP 的 GJH 个体的颈椎 JPE 增加，肌肉耐力降低。Beighton 评分较高的 GJH 个体表现出颈椎 JPE 增加和颈部肌肉耐力保持能力降低。在临床实践中，治疗师应注意这些发现，纳入本体感觉和肌肉耐力评估，并为伴有 GJM 的 NSNP 个体制定康复策略。
