Abstract
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.

A randomized controlled trial of exercise and manipulative therapy for cervicogenic headache.
Jull G, Trott P, Potter H, Zito G, Niere K, Shirley D, et al.
Summary

This trial evaluated the effect of exercise therapy in people with cervicogenic headache (Jull 2002).
This trial found that exercise was superior to no treatment in reducing headache pain and frequency
at 1 week and 1 year after 6 weeks of treatment. Exercise was also at least as effective as manipulation.

Abstract
BACKGROUND:
Episodic tension-type headache is a common problem affecting approximately 2 of 3 of the
population. The origin of tension-type headache is multifactorial, but the pathogenesis is still unclear.
In some individuals episodic tension-type headache transforms into chronic tension-type headache
(CTTH). Subjective symptoms related to the central nervous system might affect patients subjective
well-being and quality of life.
CONCLUSIONS:
Physical training and relaxation training seem to be preferable non-pharmacologic treatments for
improvement of central nervous system-related symptoms and subjective well-being for patients with
CTTH.

Abstract
OBJECTIVE:
To compare the efficacy of three 12-month training programmes on headache and upper extremity
pain in patients with chronic neck pain.
METHODS:
A total of 180 female office workers, with chronic, non-specific neck pain were randomly assigned to 3
groups. The strength group performed isometric, dynamic and stretching exercises. The endurance
group performed dynamic muscle and stretching exercises. The control group performed stretching
exercises. Pain was assessed with a visual analogue scale. Each group was divided into 3 subgroups
according to headache intensity.
RESULTS:
At the 12-month follow-up headache had decreased by 69% in the strength group, 58% in the
endurance group and 37% in the control group compared with baseline. Neck pain diminished most in
the strength group with the most severe headache (p < 0.001). In the dose analysis, one metabolic
equivalent per hour of training per week accounted for a 0.6-mm decrease in headache on the visual
analogue scale. Upper extremity pain decreased by 58% in the strength group, 70% in the endurance
group and 21% in the control group.
CONCLUSION:
All of the training methods decreased headache. However, stretching, which is often recommended
for patients, was less effective alone than when combined with muscle endurance and strength
training. Care must be taken in recommending the type of training to be undertaken by patients with
severe cervicogenic headache.
