Key result
Tension-type headache was associated with significantly reduced diastolic blood pressure and heart rate increases during sustained handgrip compared to healthy controls.
Why the study?
Is autonomic function impaired in patients with tension-type headache compared to healthy controls?
Case-Control (n=96)
Is autonomic function impaired in patients with tension-type headache compared to healthy controls?
Sympathetic function appears to be impaired in patients with tension-type headache, as evidenced by reduced cardiovascular responses to sustained handgrip.
No takes yet. Share an insight, caveat, or question.
May indicate sympathetic impairment in tension-type headache; hypothesis-generating and requires prospective validation before clinical use.
Pogačnik et al. (1993) conducted a case-control in Tension-type headache (n=96). Tension-type headache vs. Healthy volunteers was evaluated on Autonomic nervous system function (including sustained handgrip test). Tension-type headache was associated with significantly reduced diastolic blood pressure and heart rate increases during sustained handgrip compared to healthy controls.
