Objectives:

To identify predictors of prolonged recovery (ie,> 28 days) using patient demographic factors and healthy, norm-based cutoffs on a multimodal test battery in adolescents after sport-related concussions (SRCs).

Design:

Retrospective cohort. Patients were deemed recovered after successful completion of return-to-play/school protocols and received medical clearance.

Setting:

Community concussion clinic.

Patients:

Male and female adolescent student athletes diagnosed with a SRC and evaluated within 1 week of injury.

Independent Variables:

Patient demographics, medical history, injury description, computerized neurocognitive testing, vestibular/ocular testing, and symptoms at initial clinical visit.

Main Outcome Measures:

Performance on clinical testing to predict recovery duration, classified as normal (< 28 days) or prolonged (> 28 days).

Results:

A total of 201 adolescent student athletes (age= 15.3±1.4 …
