Testing of a New Computer Screen for Patients With Persistent Concussion Symptoms (PCS).

Not Applicable

Recruiting

• Conditions: Post-Concussion Symptoms
• Interventions: Device: New computer monitor

• Registration Number: NCT05660057
• Lead Sponsor: University Health Network, Toronto

Brief Summary

This study will examine whether a newly designed monitor for computers is better tolerated by concussed patients than the standard computer monitor. The information gathered from this study will contribute to the understanding of the persisting concussion symptoms including computer screen intolerance and photosensitivity, with the aim of helping those with concussions.

Detailed Description

The study will involve completing a reading task on the standard computer monitor and the newly designed computer monitor. First, participants will be asked to rate their pre-test symptoms using a SCAT-III symptom checklist. Then they will read a short story and watch moving images on one of the devices (standard computer monitor or the newly designed computer monitor) for 30 minutes or until persisting concussion symptoms of moderate severity arise. Then, they will be asked to rate their post-test clinical symptoms using a SCAT-III symptom checklist. On a second visit, 7 to 10 days later, they will do the same activity on the other device. Each visit will take 60 minutes.

The study will involve 100 patients with a history of concussion and computer screen intolerance.

Arm && Interventions

Group	Intervention	Description
Newly designed computer monitor	New computer monitor	Participants will read a short story and then watch moving images for 30 minutes or until any of their persisting concussion symptoms arise. The number and severity of symptoms will be assessed by completing SCAT -III pre- and post-study tasks.
Standard computer monitor	New computer monitor	Same participants will read a short story and watch moving images for 30 minutes or until any of their persisting concussion symptoms arise on the standard computer screen.The number and severity of symptoms will be assessed by completing SCAT -III pre- and post-study tasks.

Primary Outcome Measures

Name	Time	Method
The investigators believe that patients will subjectively perceive the new monitor to be a more effective reading device than the standard monitor.	Two visits 7 to 10 days apart	SCAT-III Symptoms checklist will be completed before and after study tasks (reading an excerpt and watching a moving image) to measure symptoms number and severity arising after the study task on a standard monitor and compare it to the newly designed monitor.
