Active clinical trials for "Headache"

Through an observational, cross-sectional study, muscle activity was compared among 21 subjects with episodic headache, 17 subjects with chronic headache and 17 age-matched healthy controls. Muscle activity was bilaterally tested with needle electromyography at rest status, targeting at myofascial trigger points (MTrPs) in the frontal, temporal, sternocleidomastoid (SCM), splenius capitis, splenius cervicis and trapezius of each subject. Headache characteristics (intensity, frequency and duration), McGill Pain Questionnaire (MPQ) and Digital Span (DS) scales were secondary outcomes. The correlation between muscle activity and headache characteristics was also analyzed. This study provides preliminary evidence of the relationship between muscle and the chronicity of headache.

Headache and backache are common symptoms following childbirth. The incidence of these symptoms have been shown to increase during the postpartum period between 5 to 12 months following delivery. By 12 months postpartum up to 45% and 65% of women experience headache and backache, respectively. While studies have reported headache and backache as frequently persistent symptoms beyond the first year postpartum, few studies have specifically interrogated women seeking specialist pain physician input or identified predisposing risk factors. Finally there is little known about typically described pain characteristics of women who suffer with chronic postpartum headache and backache. We aim to compare the prevalence of chronic headache in women that have versus have not experienced childbirth.

The aim of this study was to evaluate masticatory muscle electrical activity in post-pubertal females with forward head posture (FHP) and temporomandibular disorders (TMD) as well as in post-pubertal females with neutral head posture and with no temporomandibular disorders.

The objectives of this prospective, descriptive study are to: generate estimates of the incidence, prevalence, persistence, clinical impact and attributable risk of migraine due to hormonal contraception (HC) use; and identify predictive factors for clinically significant changes in headache attributable to HC use. The investigators hypothesize that: Most women with pre-existing migraine will have no significant change from baseline headache frequency or clinical impact attributable to HC at 3 months following initiation; a minority will report clinically significant worsening or improvement The incidence of headache and migraine in HC users will not be significantly different from their incidence in NHC users There will be identifiable risk factors for development or worsening of headache/migraine in the minority of HC users where that occurs.

The study is trying to prove that the history and physical exam (H&P) in the emergency department is the most important tool in exam of patients. The investigator is attempting to correlate the time of the H&P of residents and attendings to the accuracy of diagnosis.

This is a retrospective review of the records of patients seen at the Kilgo Headache Clinic in Alabama between 7/1/05 and 6/30/07. The goal of the study is to identify factors at the time of the initial office visit that can be used to predict failure to follow-up.

Medical expert systems in combination with portal searching meta-search engines are exploited to provide reliable patient-tailored information. A prototype of a web-based information system has been developed and is to be evaluated. Its aim is to answer the decisive question whether expert system guided internet meta-search provides a better information supply for patients seeking health information online then this is possible by using ordinary search engines or health portals. The research does neither investigate the influence of ethical nor legal aspects of internet health information supply.

The purpose of this study is to investigate the prevalence, characteristics and classification of headaches in epileptic patients.
