概括

与没有疼痛的投手相比,具有投手臂疼痛的青少年棒球投手在肘部曲方面没有显著差异. 进一步的研究应该探索其他因素,导致年轻运动员的疼痛.

科学领域:

运动医学运动医学
生物力学生物力学
儿科整形外科儿科整形外科

背景情况:

每个赛季,超过一半的青少年棒球投手都会经历投球相关的手臂疼痛.
了解与这种疼痛相关的生物力学因素对于预防伤害至关重要.

研究的目的:

为了比较青少年棒球投手在投球周期中的肘部曲,在没有投手臂疼痛的情况下.
为了测试这种假设,疼痛的投手表现出减少肘部曲的假设.

主要方法:

一项受控的实验室研究分析了38名青少年棒球投手 (平均年龄为13.3岁).
根据健康史问卷,投篮者被分为"疼痛"或"无疼痛"的组.
在快球投球过程中测量了肘部曲,并使用统计非参数映射和曼-惠特尼U测试对组进行了比较.

主要成果:

在整个投球周期中,在有疼痛和没有疼痛的投手之间,没有发现肘部曲的显著差异 (P > .05).
在疼痛和无疼痛组之间,肘部曲的峰值也没有显著差异 (U = 122;P = .09).

结论:

这项研究发现,在青少年棒球投手中,投手臂疼痛和改变肘部曲之间没有联系.
这些发现与以前的研究相反,并建议临床医生应该调查青少年投手手臂疼痛的肘部曲之外的因素.
建议专注于可修改的风险因素,如投球数量,训练量和力量缺陷.

Spinal Nerves: Plexus I

Spinal Nerves: Plexus I

Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
