To determine the effectiveness (at the 0.1 level of statistical significance) of the Align-Right (roll-shaped) cervical pillow (ARCP) on neck pain severity and headache/neck pain medication use in chronic neck pain subjects.
The design was a "before/after" (i.e., a "pre/post" trial).
Twenty-eight subjects, 25-45 yr of age with cervical spine pain of biomechanical origin of > 2 on an 11-point ordinal pain scale.
The primary outcome measure was severity of morning and evening neck pain. The secondary outcome measure was daily quantity of analgesics ingested. The data were analyzed descriptively and inferentially for clinically and statistically significant pre/post intervention differences.
Eligible subjects who successfully finished a 2-wk baseline data-gathering period by mailing in two properly completed diaries each received a pillow and four more diaries (to be filled in over the subsequent 4 wk). Three repeated-measures analyses of variance were performed using the Bonferroni-corrected level of statistical significance of 0.03. Ninety-five percent confidence intervals (for paired-samples mean differences) were also calculated for those pre/post differences that seemed descriptively clinically important.
The clinically and statistically significant reductions in neck/shoulder pain severity in this sample of chronic neck pain subjects suggest that the ARCP is an effective therapy for target populations with the same profile as this sample. Patient characteristics predicting suitability were not studied in this project.
The results suggest that the ARCP has clinically important beneficial effects on the neck pain severity of most chronic neck-pain sufferers. Further randomized clinical trial research comparing the ARCP with other commonly used cervical pillows is recommended.
确定Align-Right（滚轴形）颈椎枕（ARCP）对慢性颈部疼痛患者颈部疼痛严重程度以及头痛/颈部疼痛药物使用情况的有效性（在0.1的统计学显著性水平上）。
采用“前后”（即“预/后”）试验设计。
28名年龄在25至45岁之间、颈椎疼痛源于生物力学因素且在11点序贯疼痛量表上疼痛程度大于2的受试者。
主要结局指标为早晚颈部疼痛的严重程度。次要结局指标为每日摄入的镇痛药数量。对数据进行描述性和推断性分析，以确定干预前后在临床和统计学上的显著差异。
符合条件的受试者通过邮寄两份填写完整的日记成功完成了为期2周的基线数据收集期，之后每人收到一个枕头和另外四本日记（在接下来的4周内填写）。使用经Bonferroni校正的0.03统计学显著性水平进行三次重复测量方差分析。对于那些在描述上具有临床重要性的前后差异，还计算了95%置信区间（配对样本均值差异）。
该慢性颈部疼痛受试者样本中颈部/肩部疼痛严重程度在临床和统计学上的显著降低表明，ARCP对与该样本特征相同的目标人群是一种有效的治疗方法。本项目未研究预测适用性的患者特征。
结果表明，ARCP对大多数慢性颈部疼痛患者的颈部疼痛严重程度具有临床上重要的有益影响。建议进一步开展随机临床试验研究，将ARCP与其他常用颈椎枕进行比较。
