Determining brain fitness to fight: Has the time come?

Neuroimaging in professional combat sports: consensus statement from the association of ringside physicians

Professional boxing, kickboxing, and mixed martial arts (MMA) are popular sports with substantial risk for both acute and chronic traumatic brain injury (TBI). Although rare, combat sports athletes have died in the ring or soon after the completion of a bout. Deaths in these instances are usually the result of an acute catastrophic neurological event such as an acute subdural hematoma (SDH). Other causes may include acute epidural hematoma (EDH), subarachnoid hemorrhage (SAH), intraparenchymal hemorrhage (IPH), or a controversial, rare, and still disputed clinical entity called second-impact syndrome (SIS). Neuroimaging or brain imaging is currently included in the process of registering for a license to compete in combat sports in some jurisdictions of the United States of America and around the world. However, the required imaging specifics and frequency vary with no consensus guidelines. The Association of Ringside Physicians (an international, nonprofit organization dedicated to the health and safety of the combat sports athlete) sets forth this consensus statement to establish neuroimaging guidelines in combat sports. Commissions, ringside physicians, combat sports athletes, trainers, promoters, sanctioning bodies, and other healthcare professionals can use this statement for risk stratification of a professional combat sports athlete prior to licensure, identifying high-risk athletes and for prognostication of the brain health of these athletes over the course of their career. Guidelines are also put forth regarding neuroimaging requirements in the immediate aftermath of a bout.

Concussion occurrence and recognition in professional boxing and MMA matches: toward a concussion protocol in combat sports

Objectives: Determine, through video reviews, how often concussions occur in combat sport matches, what influence they have on the outcome, and how well non-physician personnel can be trained to recognize concussions.Methods: This is a retrospective video analysis by an 8-person panel of 60 professional fights (30 boxing and 30 mixed martial arts). Through video review, physician and non-physician personnel recorded details about each probable concussion and determined if and when they would have stopped the fight compared to the official stoppage time.Results: A concussion was recorded in 47/60 fights. The mean number of concussions per minute of fight time was 0.061 (0.047 for boxers and 0.085 for MMA). When stratifying by outcome of the bout, the mean number of concussions per minute for the winner was 0.010 compared to the loser at 0.111 concussions per minute. The fighter that sustained the first concussion ultimately lost 98% of the time. The physician and non-physician raters had high agreement regarding the number of concussions that occurred to each fighter per match. The physician raters judged that 24 of the 60 fights (11 boxing [37%]; 13 MMA [43%]) should have been stopped sooner than what occurred.Conclusion: Recognizing that the concussions often occur in combat sport matches, that the losing fighter almost always is concussed first and tends to sustain more concussions during the fight, along with the demonstration that non-physician personnel can be taught to recognize concussion, may guide policy changes that improve brain health in combat sports.

Adverse Health and Psychosocial Repercussions in Retirees from Sports Involving Head Trauma: Looking at the Sport of Boxing

Academic scholarship has steadily reported unfavourable clinical findings on the sport of boxing, and national medical bodies have issued calls for restrictions on the sport. Yet, the positions taken on boxing by medical bodies have been subject to serious discussions. Beyond the medical and legal writings, there is also literature referring to the social and cultural features of boxing as ethically significant. However, what is missing in the bioethical literature is an understanding of the boxers themselves. This is apart from their brain injuries, the debates about the degenerative brain disease known as chronic traumatic encephalopathy (CTE), and related issues about the disease. This article argues that the lives of boxers, their relationships, their careers, and their futures, also requires its own research, particularly in telling stories about their lives, and those lives and futures which boxing affects. The article uses two approaches. First, to imagine a more enduring “whole of life viewpoint” by using an extended future timeframe. Second, to consider perspectives of a person’s significant others. After reviewing the boxing literature, the article discusses social settings and then explores the hidden social relationships in life after boxing. With these longer time and close relationship viewpoints, three important themes emerge: family and kinship; age, stage and career; and the effects of boxing fatalities. These analyses are used in conjunction with relevant clinical findings which complement the telling of stories to improve medical information, and engages professional and public empathy for people’s experience of illness and difficulties in coping.

Medical retirement from sport after concussions: A practical guide for a difficult discussion

Purpose of review

In patients with a considerable history of sports-related concussion, the decision of when to discontinue participation in sports due to medical concerns including neurologic disorders has potentially life-altering consequences, especially for young athletes, and merits a comprehensive evaluation involving nuanced discussion. Few resources exist to aid the sports medicine provider.

Recent findings

In this narrative review, we describe 10 prototypical vignettes based upon the authors' collective experience in concussion management and propose an algorithm to help clinicians navigate retirement discussions. Issues for consideration include absolute and relative contraindications to return to sport, ranging from clinical or radiographic evidence of lasting neurologic injury to prolonged concussion recovery periods or reduced injury threshold to patient-centered factors including personal identity through sport, financial motivations, and navigating uncertainty in the context of long-term risks.

Summary

The authors propose a novel treatment algorithm based on real patient cases to guide medical retirement decisions after concussion in sport.

Fighting to keep a sport safe: toward a structured and sport-specific return to play protocol

Combat sports are growing in popularity, viewership, and participation. The nature of these sports involves repetitive head contact, yet unlike most other professional contact sports, there are no endorsed guidelines or mandates for graduated and systematic return to play following concussion. Here, we review the literature related to concussion and fighting sports, and propose guidelines for concussion management and safe return to play following concussion.
