This paper investigates secondary outcomes (headache) in a randomized controlled trial with physical exercise among office workers with neck/shoulder pain.
A total of 198 office workers with frequent neck/shoulder pain were randomly allocated to either one of two intervention groups (10 weeks of resistance training with elastic tubing for 2 or 12 minutes per day, 5 times a week) or the control group, which received weekly health information. Secondary outcomes included changes in frequency, intensity, and duration of headache after ten weeks.
Compared with the control group, headache frequency decreased in the 2- and 12-minute intervention groups [0.64 days/week (95% confidence interval [95% CI]) 0.23-1.0) and 0.79 days/week (95% CI 0.37-1.2), corresponding to a 43% and 56% decrease from baseline, respectively]. Intensity and duration of the remaining headaches were unaffected.
Two minutes of daily resistance training for ten weeks reduces headache frequency among office workers with neck/shoulder pain. The vast number of adult workers suffering from one or two days of weekly headaches and who could potentially comply with and benefit from brief exercise programs stresses the applicability of our findings.
本研究调查了颈肩痛办公室工作人员接受身体锻炼的随机对照试验中的次要结局（头痛）。
共 198 名颈肩痛频繁发作的办公室工作人员被随机分配到两个干预组（每周 5 次，每天进行 2 或 12 分钟的弹性管抗阻训练）或对照组，对照组每周接受健康信息。次要结局包括 10 周后头痛的频率、强度和持续时间的变化。
与对照组相比，2 分钟和 12 分钟干预组的头痛频率降低[每周 0.64 天（95%置信区间 [95%CI]）0.23-1.0）和每周 0.79 天（95%CI 0.37-1.2），分别对应于基线的 43%和 56%的减少]。其余头痛的强度和持续时间没有变化。
10 周每天 2 分钟的抗阻训练可减少颈肩痛办公室工作人员的头痛频率。大量每周头痛 1-2 天且可能遵守和受益于短暂运动计划的成年工人强调了我们研究结果的适用性。
