Sports Bracing
Sports Bracing for Athletes
Should athletes wear braces for injury prevention?
The evidence for prophylactic bracing (wearing a brace to prevent a first injury) is strongest for the ankle. Lace-up or semi-rigid ankle braces significantly reduce the rate of ankle sprains in athletes with a prior sprain history. The evidence for prophylactic knee bracing is weaker. Bracing after an injury, to protect a healing structure and allow return to sport, has clearer support across ankle, knee, elbow, and wrist.
Prophylactic versus functional bracing in sport
Prophylactic bracing means wearing a support to prevent a first or recurrent injury during athletic activity. Functional bracing means wearing a support to protect a previously injured structure during the return-to-sport phase. The evidence base and clinical rationale differ between these two uses.
For ankle prophylactic bracing, the evidence is clear and well-studied. Multiple randomized trials show that lace-up ankle braces reduce the rate of ankle sprains in basketball, volleyball, and soccer players, particularly those who have sprained their ankle before. The protective effect is meaningful even in players without a prior sprain, though the absolute benefit is smaller.
Ankle and knee bracing in sport
Ankle bracing is the most evidence-supported form of prophylactic bracing across team sports. Many athletic trainers and team physicians routinely brace athletes with a prior ankle sprain history during practices and games. The brace does not eliminate sprain risk, but the reduction in sprain incidence and severity is consistent across studies. Compliance is important; a brace left in the locker room provides no benefit.
Prophylactic knee bracing for contact sports became popular in the 1980s but the evidence for preventing MCL or ACL injuries is not strong. Post-surgical knee bracing after ACL reconstruction is more clearly supported as a way to protect the reconstruction during the early return-to-activity phase.
Upper-limb bracing in sport
Counterforce elbow straps for tennis elbow allow athletes to continue playing during recovery by redistributing forces at the tendon attachment. Wrist braces are used in contact sports to limit wrist hyperextension, particularly for athletes with a history of wrist sprains or scaphoid fractures. Hinged wrist braces are used in sports like skateboarding and snowboarding to limit the wrist extension and deviation that occur during falls.
Shoulder braces for sport are used primarily after dislocation or AC joint injury. A custom shoulder harness may limit the external rotation that causes anterior dislocation recurrence, allowing earlier return to contact sport. These are typically prescribed and custom-fitted rather than purchased off the shelf.
What to know
Key things to understand
- Ankle bracing has the strongest prevention evidence. Lace-up and semi-rigid ankle braces consistently reduce sprain rates in team sport athletes, especially those with prior sprains.
- Functional bracing supports return to sport. Protecting a healing structure with a brace during the return-to-play phase has clearer support than injury prevention in uninjured athletes.
- Counterforce straps allow continued play with elbow pain. Athletes with tennis elbow can often continue sport using a forearm strap while pursuing tendon rehabilitation.
- Compliance determines effectiveness. A brace only works if it is worn consistently; athlete education on correct use is as important as the brace itself.
- Bracing does not replace rehabilitation. Returning to sport in a brace without addressing the underlying weakness or instability increases long-term re-injury risk.
