Concussion Assessment: Managing Head Impacts in Basketball Players

Introduction

Concussions are more common in contact sports like basketball than most people think. They can result from collisions while boxing out, hitting the rim during a dunk, or striking the head on the floor. Compared to fractures, the danger of a concussion lies in the “invisible injury” and “Second Impact Syndrome.”

This article integrates the recommendations of the international Concussion in Sport Group (CISG) consensus, providing a complete protocol from the sideline to return to play.

Definition

A concussion refers to a temporary disturbance of brain function caused by biomechanical force. Common characteristics include:

• Brief alteration in consciousness
• Decline in cognitive function
• Abnormalities in balance and coordination
• Changes in mood and sleep

Red Flag Symptoms

Immediate medical attention is required for any of the following:

• Loss of consciousness for more than 1 minute
• Repeated vomiting
• Persistently worsening headache
• Seizures
• Unequal pupil size
• Neck pain with inability to move
• Focal neurological deficits

SCAT5 Assessment

The international standard tool, which includes:

• Glasgow Coma Scale
• Maddocks questions (sideline orientation questions)
• Symptom evaluation (22 items)
• Cognitive testing (memory, attention)
• Balance testing (mBESS)

It is recommended that every basketball team train at least one SCAT5 assessor.

Sideline Management (CRT5)

1. Remove from play immediately
2. Do not leave the athlete alone
3. Do not drive home
4. Do not consume alcohol
5. Continue observation for 24 hours
6. Medical evaluation the next day

Six-Stage Return to Play

Stage	Content	Duration
1	Complete rest	24–48 hours
2	Light aerobic exercise	Heart rate < 70% max
3	Sport-specific aerobic exercise	Running, cycling
4	Non-contact training	Shooting, passing
5	Full training	Full contact
6	Return to competition	Physician approval

Each stage requires at least 24 hours, and progression to the next stage only occurs if symptom-free. If symptoms reappear at any stage, the athlete must step back to the previous stage.

Second Impact Syndrome

Sustaining another injury before full recovery can cause fatal brain swelling, particularly in young athletes. This is the most important reason for enforcing complete recovery.

Practical Recommendations

• Stop playing if something “feels off”; do not push through
• Teams should establish a concussion assessment and documentation protocol
• Coaches and athletic trainers should receive concussion training
• During the acute phase, do not sleep alone and avoid alcohol
• Screen time should be controlled
• Gradually return to school and academics to avoid cognitive overload
• The sports science teams at National Taiwan University of Sport and National Taiwan Normal University have complete concussion protocols

Prevention Strategies

• Strengthen neck musculature
• Learn proper falling techniques
• Promote fair-play education
• Pre-game equipment inspection

Conclusion

A concussion must never be “toughed out.” For basketball players, missing one extra game is far better than affecting brain function for a lifetime. Please respect the six-stage protocol to protect yourself and your teammates.
