Trial Outcomes & Findings for Neurofeedback-enhanced Mindfulness Meditation in Traumatic Brain Injury (NCT NCT02615535)

NCT ID: NCT02615535

Last Updated: 2020-03-30

Results Overview

Measures common symptoms after head injury. This scales ranges from 0-4 on 22 items, for a minimum score of 0 and a maximum score of 88. Higher scores mean a greater severity of symptoms.

SECONDARY outcome

Timeframe: baseline and six weeks

A subject is provided with a key matching nine numbers to nine unique symbols. Numbers are then provided in random order and subjects have 120 seconds to match as many numbers with symbols as possible. All correct responses are scored. Scores range from 0 to 135. Scores are later scaled from 1 to 19. Higher scores mean a better outcome.

SECONDARY outcome

Timeframe: baseline and six weeks

Subjects are asked to sequence numbers and letters represented on a page as quickly as then can. Results are measured in seconds, ranging from 0 (hypothetically) to an infinite number (hypothetically). Results are scaled from 1 to 19. Lower scores mean a better outcome.
