abstract="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. <br><br>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 &quot;symptom instability&quot; 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.
