Trial Outcomes & Findings for Improving Functions in MTBI Patients With Headache by rTMS (NCT NCT01948947)

NCT ID: NCT01948947

Last Updated: 2018-03-26

Results Overview

The primary outcome time-point measurement will be averaged from each day the subject is enrolled in the study for each of the 3 time point periods: pre-treatment baseline, 1-week follow-up and 1-month follow-up. The results depict change in the composite score: intensity (scale of 0-10) x duration (# of hours) x frequency (# headaches per week). The larger composite score for each subject, the worse the debilitating headaches.

PRIMARY outcome

PRIMARY outcome

Timeframe: Subjects will have a total of 9 visits over the span of 3 months, the baseline, 1-week follow-up and 1-month follow up will qualify as a time point at which the outcome is measured and averaged.

The persistent headache measure was assessed through a daily headache log over the course of the subjects participation in the study and averaged for the time point period of baseline, 1-week and 1-month results. The persistent headache is based on a scale of 0-10, the higher the persistent headache intensity averaged score the worse the persistent headache.

PRIMARY outcome

Timeframe: Subjects will have a total of 9 visits over the span of 3 months, the baseline, 1-week follow-up and 1-month follow up will qualify as a time point at which the outcome is measured.

The persistent headache prevalence measure was assessed through a daily headache log over the course of the subjects participation in the study and collected at baseline, 1-week and 1-month. The persistent headache is defined as having had 3+ continuous headaches over the course of the time point periods and was coded as either yes or no. The results indicate the percent change in the prevalence of persistent headaches for the subjects at the time points. A larger reduction percent indicates a larger decrease in subjects with those persistent headaches.

SECONDARY outcome

Timeframe: Subjects will have a total of 9 visits over the span of 3 months and 3 of those visits will qualify as a time point at which outcome is measured.

Subjects assessed how their headaches interfered with their mood through the Hamilton Rating Scale for Depression assessment at baseline, 1-week follow-up and 1-month follow-up. The outcome was measured by adding the score of each question on the assessment and then comparing the averaged scores at the different time points. The larger the depression score, the more severe the depression. A larger percent change in depression score indicates a change in the severity of the depression.
