Concussions have become a significant public health concern with rising incidence rates. Concussions have been shown to occur concurrently with neck injuries, such as whiplash-associated-disorder, therefore, understanding the role of the neck in concussions is important.
To determine if there is a relationship between cervical muscle endurance and either concussion incidence, or concussion recovery in university athletes. Specifically, the primary aim was to investigate a relationship between pre-season deep neck flexor endurance test (DNFET) time in those who sustained an in-season injury versus those who did not. The secondary aim is to determine correlation in DNFET times and concussion recovery.
Longitudinal observational study.
Pre-season DNFET was performed on university athletes. In the event of a concussion, cervical endurance and neuromuscular adaptation was re-assessed with the DNFET. Rehabilitative exercises were prescribed, as required, and DNFET was measured at subsequent treatments.
There was no significant difference between pre-season DNFET times and concussion incidence (p = 0.55). However, there was a moderate correlation between DNFET times and concussion recovery (R = 0.47, p = 0.001) whereby DNFET times improved predictively throughout rehabilitation.
While no statistically significant relationship was found between DNFET and concussion incidence, a significant clinical relationship was present with recovery. The validity of the DNFET test as a means for assessing risk or measuring recovery requires additional research.
随着发病率的上升，脑震荡已成为一个重大的公共卫生问题。脑震荡与颈部损伤（如挥鞭样损伤）同时发生，因此，了解颈部在脑震荡中的作用很重要。
确定颈肌耐力与大学生运动员脑震荡的发生率或康复之间是否存在关系。具体来说，主要目的是调查在赛季中受伤的人与未受伤的人之间，赛前深层颈部屈肌耐力测试（DNFET）时间是否存在关系。次要目的是确定 DNFET 时间与脑震荡康复之间的相关性。
纵向观察性研究。
对大学生运动员进行赛前 DNFET。一旦发生脑震荡，就会对颈部耐力和神经肌肉适应性进行重新评估，使用 DNFET。根据需要开出康复锻炼处方，并在随后的治疗中测量 DNFET。
赛前 DNFET 时间与脑震荡发生率之间无显著差异（p=0.55）。然而，DNFET 时间与脑震荡康复之间存在中度相关性（R=0.47，p=0.001），即 DNFET 时间在康复过程中得到了改善。
虽然 DNFET 与脑震荡发生率之间没有统计学上的显著关系，但与康复之间存在显著的临床关系。DNFET 测试作为评估风险或测量康复的一种手段的有效性需要进一步研究。
