The mechanisms of a concussion place stress on the cervical spine like that of a whiplash event, which can result in cervical spine dysfunction. This study aimed to determine if underlying cervical spine mobility and sensorimotor function deficits occur in individuals who are post-concussion with near resolution of symptoms.
Twenty-five participants with a self-reported concussive event within a year (PC group: post-concussion 157 120 d, 9 men, age: 25 ± 8 yr) and 26 comparable peers (Peer group, 9 men, age: 25 ± 7 yr) were tested. The Post-Concussion Symptom Scale (PCSS) quantified residual concussion symptoms. Participants completed cervical joint position error (JPE) and cervical spine joint mobility tests blinded from each other. Group mean differences were analyzed using t-tests.
The PC group had minimal symptoms (PCSS = 6.8 ± 6.5) but substantial differences in JPE tests compared to the Peer group (PC = 7.4 ± 1.8 cm; PG = 5.6 ± 1.1 cm; < .001). Those PC participants with pain during joint testing ( = 15) had worse JPE (Painful = 8.1 ± 1.8 cm, No-pain = 6.3 ± 1.6 cm; = .02) and less averaged lower cervical spine joint mobility compared to PC participants without pain (Painful = 0.66 ± 0.22, No-pain = 0.87 ± 0.19; = .02, Normal motion = 1.0).
Following a concussion, it is a reasonable recommendation to screen the cervical spine to identify impairments in joint mobility and JPE that contribute to neck dysfunction.
脑震荡的机制对颈椎造成的压力类似于挥鞭伤,这可能导致颈椎功能障碍。本研究旨在确定在症状基本缓解后的脑震荡患者中是否存在潜在的颈椎活动度和感觉运动功能缺陷。
25 名参与者在一年内报告有脑震荡事件(PC 组:脑震荡后 157120d,9 名男性,年龄:25 ± 8 岁),26 名可比同龄人(对照组,9 名男性,年龄:25 ± 7 岁)。使用脑震荡后症状量表(PCSS)量化残留的脑震荡症状。参与者在彼此不知情的情况下完成颈椎关节位置误差(JPE)和颈椎关节活动度测试。使用 t 检验分析组间均值差异。
PC 组症状轻微(PCSS=6.8±6.5),但与对照组相比,JPE 测试差异显著(PC=7.4±1.8cm;PG=5.6±1.1cm;<.001)。在关节测试时感到疼痛的 PC 参与者(n=15)的 JPE 更差(疼痛=8.1±1.8cm,无痛=6.3±1.6cm;=0.02),与无疼痛的 PC 参与者相比,下颈椎关节活动度平均值较低(疼痛=0.66±0.22,无痛=0.87±0.19;=0.02,正常运动=1.0)。
脑震荡后,建议对颈椎进行筛查,以识别对颈部功能障碍有贡献的关节活动度和 JPE 障碍。
