Disclosures

• 3.8 million sports-related concussions per

year in U.S1

• Long-term effects are on ongoing point of

concern

• Attention across media, scientific

community and sporting leagues has increased – Plethora of new protocols to improve diagnosis and management

Background

• More prevalent research in NFL, MLB, NHL
• NCAA basketball

– 3,687 concussions from 2009-2014 with linear yearly increase across men’s basketball2

Background: Current Literature

Cbssports.com

• Mean 14.9 concussions per

season

• Significant increase in games

missed after concussion

• 10 seasons
• No statistically significant decrease in

post-concussion performance after 5 games

• Purpose
• To determine effects of sports-related

concussion on long-term rate of return to play (RTP) and player performance in National Basketball Association (NBA) athletes

• Hypothesis
• Player performance will be negatively

affected after experiencing a primary concussive injury

Objective

• Study Design

– Case series of NBA athletes sustaining a concussion from 2006 to 2014

 Data obtained through team injury/game

reports and media releases – Demographic data and performance related statistics recorded and compared between season prior to, and after, injury – Return to play (RTP) defined as return to competition in at least one game following the season of injury

Methods

Results

• 13% unable to return to play in immediate

season following injury – Mean age 27.2 years (p=0.18)

• By Position

– 83% Forwards – 89.2% Guards – 90.5% Centers

Results: Return to Play

Results: Player Performance

• 13% of NBA athletes were unable to RTP following

concussion from 2006-2014

• No significant differences in games/minutes played,

field goal percentage or player efficiency rating following concussion Conclusion: Despite the reported long-term effects and variable recovery times after experiencing a concussion, our findings showed no long-term impact

• n an NBA athlete’s playtime or performance in the

season following a concussion.

Summary

• Difficult to verify accuracy or completeness
• f available injury data
• Data on baseline attrition rate of NBA

athletes currently not available

• Next Steps:

– Use injury-specific information to identify risk factors predictive of negative performance or decreased RTP following concussion
