Concussion in NBA: how are the performances then?

The terms mild brain injury, mild traumatic brain injury, mild head injury, minor head injury, and concussion, can all be used with the same meaning, although the latter is often treated as a narrow category. Concussion is often defined as trauma to the skull with a temporary loss of brain function, accompanied by a variety of physical, cognitive and emotional symptoms, which can also be so subtle that they are not easily recognized.

Treatment involves physical and cognitive monitoring and rest. Symptoms usually resolve within three weeks, although they may persist or complications may occur. It appears that those who have suffered a concussion are more susceptible to another such event, especially if the new injury occurs before the symptoms of the first have been completely resolved.

The study: Performance After Concussion in National Basketball Association Players, published on the Orthopedic journal of sports medicine, explained: "Concussions have received national attention in collision sports such as football, soccer, and hockey, but less focus has been placed on basketball.

To determine return-to-play (RTP) and player performance in the first and second season after concussion in National Basketball Association (NBA) players.
Descriptive epidemiology study
. An online database of publicly available NBA athlete injuries was queried for instances of "concussion" between 2010 and 2018.

The age at injury, team, position, height, weight, body mass index, NBA experience, date of concussion, date of return, and seasons played postconcussion was recorded for each player. Regular-season statistics (games started, games played, minutes played, and player efficiency rating [PER]) were compiled for the season before, and 2 seasons immediately after, injury.

Kaplan-Meier survivorship plots were computed for athlete RTP and retirement endpoints. A total of 81 injuries were identified from 2010 to 2018, with a rate of 2.0 concussions per 100 player-years. Overall RTP was 100% after concussion, with nearly all (88%) returning in the season of injury; 12% of players experienced a season-ending concussion.

RTP averaged 37.3 days after injury, varying widely (range, 2-291 days). Compared with preinjury season (78.0%), athletes played in significantly fewer overall games in the season of injury (36.6%; P <.0001), as well as 1 (69.5%; P = .0229) and 2 seasons postinjury (73.2 %; P = .3192).

PER scores were not significantly different across the study period. Each point increase in a player's preinjury PER score was associated with a 2.4% decrease in PER from the preinjury season to season of injury (P = .0016) and a 3.1% decrease from preinjury to season after injury (P = .0053).

Each increasing year of age or year of experience was associated with 5% decline in PER score at 1 season after injury. NBA players had a high RTP after concussion, with most returning in the same season as the injury. Players sustaining concussions played significantly fewer games for at least 2 seasons after injury.

Performance via PER did not change across the entire cohort; however, players with higher preinjury PER, and older players were more likely to sustain a greater decline in performance after injury. "
