Contact sports place athletes at risk for cervical spine injury. Protective helmets and shoulder pads worn by football and ice hockey athletes alter cervical spine alignment. The effect of helmet and shoulder pads on neck alignment in lacrosse athletes is not known.
Helmets and shoulder pads worn by lacrosse athletes alter cervical spine alignment.
Controlled laboratory study.
Sagittal plane cervical spine alignment was evaluated in 16 uninjured male collegiate lacrosse players using computed tomography. Patients were immobilized in the supine position on a standard spine board. Testing was performed without equipment, with both helmet and shoulder pads in place, and with the helmet removed. Angular measurements of the cervical spine were made and analyzed.
The presence of both the helmet and shoulder pads caused an increase in overall cervical extension (mean, 6 degrees ) compared with the absence of both pieces of equipment (P = .002). Helmet removal alone resulted in a mean increase in cervical flexion of 4.7 degrees in the upper cervical spine compared with the presence of both pieces of equipment (P = .011). Compared with the absence of equipment, shoulder pads caused increased cervical flexion in the lower cervical spine (mean, 4.4 degrees ; P = .036).
Protective equipment worn by lacrosse athletes causes statistically significant increases in cervical extension, and its removal causes statistically significant increases in cervical flexion. This alteration is different from that previously reported for protective equipment in football and ice hockey.
The authors' recommendation is that both lacrosse helmets and shoulder pads be left in place until they can be completely removed in a controlled fashion. The effect of external equipment on neck position is different for lacrosse compared with football and ice hockey.
接触性运动使运动员有颈椎损伤风险。橄榄球和冰球运动员佩戴的防护头盔和肩垫会改变颈椎排列。长曲棍球运动员佩戴的头盔和肩垫对颈部排列的影响尚不清楚。
长曲棍球运动员佩戴的头盔和肩垫会改变颈椎排列。
对照实验室研究。
使用计算机断层扫描对16名未受伤的男性大学长曲棍球运动员的矢状面颈椎排列进行评估。患者仰卧固定在标准脊柱板上。分别在不佩戴装备、同时佩戴头盔和肩垫以及摘下头盔的情况下进行测试。对颈椎进行角度测量并分析。
与不佩戴这两种装备相比，同时佩戴头盔和肩垫会使颈椎整体伸展增加（平均6度）（P = .002）。与同时佩戴这两种装备相比，仅摘下头盔会使上颈椎的颈椎前屈平均增加4.7度（P = .011）。与不佩戴装备相比，肩垫会使下颈椎的颈椎前屈增加（平均4.4度；P = .036）。
长曲棍球运动员佩戴的防护装备会使颈椎伸展在统计学上显著增加，而摘下装备会使颈椎前屈在统计学上显著增加。这种改变与先前报道的橄榄球和冰球防护装备的情况不同。
作者的建议是，在能够以可控方式完全取下之前，长曲棍球头盔和肩垫都应保持佩戴状态。与橄榄球和冰球相比，外部装备对长曲棍球运动员颈部位置的影响有所不同。
