Objective
The purpose of the study was to determine the association between trapezius muscle tenderness and tension-type headache among female office workers.Methods
Through a questionnaire survey, 256 female office workers with tension-type headaches reported the level of palpable tenderness (“no,” “some,” or “severe tenderness”) in the trapezius muscle. The number of days with headache (“0-7,” “8-14,” or “>14”), intensity (“low,” “moderate,” or “high”), duration of headache (“<8 hours per day,” “>8 hours per day,” and “all day”), and use of analgesic medications were reported. Odds ratio (OR) for tenderness in the trapezius muscle (“no/some” vs “severe tenderness”) as a function of days with headache, intensity of headache, duration of headache, and use of analgesic medications were calculated using a binary logistic regression controlling for age and body mass index.Results
After adjustments for confounders, a strong association was found between the level of trapezius muscle tenderness and intensity of headache (moderate intensity, OR 2.45; 95% confidence interval [CI] 1.08-5.54; high intensity, OR 7.51 [95% CI 2.65-21.29]) and days with headache (>14 days, OR 4.75 [95% CI 1.41-15.89]). No association was observed for duration of headache or use of analgesic medications.Conclusions
For the participants studied, there was a strong association between trapezius muscle tenderness and the level of intensity and the number of days with a headache among female office workers. No association was seen for duration of headaches or use of analgesic medications. 相似文献Methods: The study is based on observations of 20 physical therapy sessions and 20 interviews with PTs. We performed a systematic content analysis informed by enactive theory regarding the interactions and co-creation of meaning.
Results and Discussion: CR emerged in reciprocity with the PTs’ interaction with the infant and parent(s). Based on the sensitivity to the infant’s motor abilities and signs of engagement as well as the parents’ need of support and education, the PTs individualized and reasoned about their therapeutic approach. This interactional CR was vulnerable: infant disengagement, parent expectations, and PT preoccupations could obfuscate interactions and hamper CR.
Conclusion: Through mutuality and engagement with the infant and parent(s), the PTs allow the autonomy of interaction to emerge and shape the translation of CR into successful therapeutic actions and learning together with the infant and parent(s). 相似文献
