Manual therapy for tension-type headache related to quality of work life and work presenteeism: Secondary analysis of a randomized controlled trial.
OBJECTIVE
The objective of this research is to evaluate the efficacy of manual therapy for tension-type headache (TTH) in restoring workers quality of work life, and how work presenteeism affects this relation.


DESIGN
This study is a secondary analysis of a factorial, randomized clinical trial on manual therapy interventions. Altogether, 80 patients (85% women) with TTH and without current symptoms of any other concomitant disease participated.


INTERVENTIONS
An experienced therapist delivered the treatment: myofascial inhibitory technique (IT), articulatory technique (AT), combined technique (IT and AT), and control group (no treatment).


RESULTS
In general, all treatments as compared to our control group had a large effect (f≥.69) in the improvement of participants' quality of work life. Work presenteeism interacted with TTH treatment type's efficacy on participant's quality of work life. The inhibitory technique lead to higher reports of quality of work life than other treatment options only for participants with very low frequency of work presenteeism. In turn, TTH articulatory treatment techniques resulted in higher reports of quality of work life for a high to very high work presenteeism frequency.


CONCLUSION
Articulatory manipulation technique is the more efficient treatment to improve quality of work life when the frequency of work presenteeism is high. Implications for future research and practice are discussed.
