Summary
This study optimized concussion assessment for collegiate athletes. Symptom reporting, Balance Error Scoring System (BESS), and Standardized Assessment of Concussion (SAC) scores are key for diagnosis.
Area of Science:
- Sports Medicine
- Neurology
- Athletic Training
Background:
- Medical organizations recommend multifaceted concussion assessment in sports.
- Existing tools vary in sensitivity and specificity.
- Limited research evaluates combined tool efficiency in diverse collegiate athletes over time.
Purpose of the Study:
- Optimize concussion assessment battery within 72 hours of injury.
- Determine optimal baseline retesting frequency for collegiate athletes.
Main Methods:
- 1458 NCAA athletes with 1640 concussions evaluated 2014-2017.
- Standardized protocol used for baseline and up to three post-injury evaluations (within 72 hours).
- Classification and regression tree analyses identified efficient assessment pathways.
Main Results:
- Symptom evaluation, firm-surface BESS, and SAC scores performed best against same-season baseline.
- Optimized sensitivity: 61% (within 1h), 67% (1-24h), 55% (24-72h) with same-season baseline data.
- Assessment effectiveness varied based on time from injury and baseline data availability.
Conclusions:
- Key concussion assessments identified for quantifying post-concussion performance in student athletes.
- Effectiveness maximized with same-season pre-injury evaluations.
- Continue focusing on symptom reporting, postural control, and neurocognitive screening for diagnosis.

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

The two sources for collecting information are primary and secondary. After gathering information, interpretation and validation help to complete the data. The purpose of assessment is to establish data with the initial information, to interpret data about the patient's perceived needs and health problems, and to respond to these problems identified.

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
