N2 - Objective This paper investigates secondary outcomes (headache) in a randomized controlled trial with physical exercise among office workers with neck/shoulder pain. Methods 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. Results 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. Conclusions 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.
