NCT04837066 | Completed

• 1 other identifier: IRB-FY20-339
• Study Type: observational
• Target: 100
• Locations: 1 country
• Sites: 1

Brief Summary

The purpose of this study is to determine the value of including dynamic vision testing into California State University, Northridge (CSUN) Athletics' established concussion protocol. The study's hypotheses are 1) dynamic vision testing will reveal vision impairments right after a person sustains a concussion, 2) these impairments may still be present upon clearance to return to play.

Conditions

Head Injury; Sport Injury; Concussion, Brain

Outcome Measures

Primary Outcomes (3)

• 6-Condition BESS

  Number of errors and time subject was able to hold position

  August 15, 2021 - August 15, 2024

• Gaze Stabilization Test (GST)

  Maximum head velocity in degrees/second

  August 15, 2021 - August 15, 2024

• Dynamic Visual Acuity (DVA)

  Log of minimal angle resolvable units (LogMAR). The number of lines on an eye chart that are lost with head moving (DVA) compared to the head steady condition, known as static visual acuity (SVA)

  August 15, 2021 - August 15, 2024

Study Arms (1)

Student Athletes

D1 student athletes currently enrolled in a large public university in the Los Angeles area and competing in one of the following sports: men's and women's soccer, men's and women's basketball, women's water polo and men's volleyball.

Diagnostic Test: Dynamic Vision Testing (Bertec Vision Advantage System) and Balance Error Scoring System

Interventions

Dynamic Vision Testing (Bertec Vision Advantage System) and Balance Error Scoring System DIAGNOSTIC_TEST

Assessment tool and computerized tests designed to evaluate postural stability and vestibulo-ocular reflex (VOR) function while assisting with return to play decision after a sports-related concussion.

Eligibility Criteria

• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

D1 athlete who is currently an enrolled student, actively competing in specific sport, provides consent to participate, and able to complete the testing protocol.

You may qualify if:

• California State University Northridge athletes
• Participants are able to give consent to participate in the study
• Completion of preseason testing for the 6-condition, BESS, DVA, GST with the research team
• Sampling of convenience on a volunteer basis

You may not qualify if:

• Athletes with preseason baseline tests on BESS or DVA that are not within the normative value range for an unimpaired individual.
• The initial 6- condition BESS score is \>20 errors
• The subject is unable to attain a minimum of 85 degrees per second of horizontal head rotation when performing the DVA test.
