SYMPTOM INSTABILITY AND A PROPOSED CLASSIFICATION SYSTEM FOR THE PHYSICAL THERAPY MANAGEMENT OF SPORTS-RELATED CONCUSSION.

Background
Individuals can experience headaches, dizziness, cervical dysfunction, balance disturbances, fatigue, and oculomotor impairments following a concussion. Patients with sports-related concussions are not a homogenous group but rather heterogenous groups with mixed clinical findings.


Purpose
The purpose of this clinical commentary is to propose a classification system developed specifically for the physical therapy management of sports-related concussions.


Description
The concept of "symptom instability" was introduced to assist with classifying patients. The time period post-concussion, symptom instability, and the ability to identify symptom triggers were used as defining criteria. The end result was a classification system with five clinical subgroups.


Relationship to Clinical Practice
The classification system assists in forming homogeneous groups. The grouping of patients into these subgroups can allow for improved efficiency of organizing treatment plans.
