The History of Sports Concussion Management in South Africa


As in most countries, concussion management in South Africa up until the last decade followed neurosurgical guidelines that were based primarily on the severity of 2 symptoms – loss of consciousness and amnesia (memory loss). The criteria were often subjective and difficult to measure and, as a result, guidelines to concussed players may have been based on subjective grading systems (of which there are many) and were poorly individualised.

The emergence of computerised neuropsychological testing, batteries of tests that enable the clinician to gain more insight into the function of the athlete’s brain, provided new impetus to concussion research and refocused our clinical approach. Well-validated testing protocols such as ImPact, Cogsport, Headminders and ANAM allow clinicians to assess response times, memory and information processing and compare scores obtained after injury to a player’s pre-injury or “baseline” score.

This renewed momentum gave rise to the First International Congress on Sports Concussion held in Vienna in November 2001 (See Research: International Consensus).. At this meeting, concussion was given a more complete definition and neuropsychological testing was acknowledged as a cornerstone of management. Individualised concussion management rather than grading and “pigeon-holing” cases was accepted as being the most appropriate strategy.

Other significant consensus meetings include the Second International Conference held in Prague in 2003 and the American College of Sports Medicine’s (ACSM) Consensus Statement in November 2005 (See Research: International Consensus).

South African Sports Concussion Centres were first established by Dr. Jon Patricios and Dr. Ryan Kohler in 2003 with the purpose of improving the medical management of concussion in the South African sports environment using a combination of repeated clinical assessments and scientifically validated computer brain function testing. This individualised concussion management system was adapted from the International Conferences on Concussion and subsequent Consensus Statements. We incorporated many of the protocols we had been using in our experience with professional athletes in particular, high level rugby players. Sports Concussion Centres introduced the concept of multidisciplinary assessment and management of concussed individuals via interaction between:


Sports Physicians – co-ordinating field side and clinical assessments
Neurosurgeons / Neurologists – assessment of complicated and hospital cases
Neuropsychologists – overseeing neuropsychological testing and follow-up of post concussion syndrome complications
Radiologists – CT and MRI scan interpretation
Exercise therapists – assist with return-to-sport programmes


These Centres, originally in Johannesburg, Cape Town and Stellenbosch, have now spread countrywide. A concussion management protocol was formulated by the Medical Advisory Commission of SA Rugby spearheaded by Dr. Ryan Kohler and Dr Ismail Jakoet (Medical Director of SA Rugby) at the South African Rugby Union and is currently used at the national, Super 14 and provincial levels of South African rugby.

In order to allow the protocols utilised in professional sportspersons to be accessible to amateur athletes and scholars, the Pharos Sports Concussion Programme was launched in 2004. The subsidy by Pharos Medical Plan allowed us to structure a package of R200 (±US$25) per pupil that included computerised testing and clinical assessments for the year.


The implementation of the protocol has had a number of benefits. These include:


• Educating the sporting public as to the potential dangers of concussion.
• Providing specific individualised and scientific data on the management of concussion with respect to return to play decisions for which there previously existed only vague return to play guidelines.
• Providing a sound medico-legal framework in which to more accurately determine when a player is fit to return to play.
• Affording opportunities for data collection and research in the area of concussion in sport.


The computerised cognitive function test that is used and which has been validated in numerous peer-reviewed scientific journals is the CogSport test from Australia. Sportspersons performing this card-based test can complete the testing in about 20 minutes and then the test is emailed to Australia and a report is generated in a very short space of time. The CogSport was identified as the most affordable and appropriate test available for the South African scenario by the Medical Research Committee of SA Rugby.

Despite the emergence of computerised brain function testing, clinical assessment of the concussed sports person is still seen as of the utmost importance. This was particularly highlighted in the ACSM Consensus Statement. As a result, we have developed both a symptom analysis system and a clinical examination incorporating both internationally recommended criteria as well as techniques evolving from our own experience.


The assessment of the concussed player now takes several steps:


• Education – definition, presentation and potential dangers of concussion
• Baseline computer assessment (preseason)
• Initial clinical evaluation
• Follow-up clinical evaluation
• Follow-up computer testing
• Stepwise return to sport exercise programme


We are confident that the strategies we have developed for the management of concussion match international standards. The challenge is to make these protocols accessible to as many individuals, particularly scholars, in South Africa.

To facilitate this Sports Concussion South Africa is a trade mark that serves as an umbrella title under which all educational initiatives will fall. The Pharos Sports Concussion Programme will be the instrument via which the educational initiatives of Sports Concussion South Africa are taken to the sporting community, in particular, schools.

The Sports Concussion South Africa and Pharos Sports Concussion Programme initiatives will be presented at a 2 hour Sports Concussion Seminar at the American College of Sports Medicine Meeting in New Orleans in May-June 2007. Dr Patricios and Kohler are privileged to be afforded the opportunity to participate in this session with Dr Stanley Herring, Chairperson of the ACSM Concussion Consensus Committee and Dr Margot Petukian of Princeton University.




In addition Dr Patricios and Kohler would like to acknowledge the input of Dr Ismail Jakoet of SA Rugby, Dr Alex Collie of Cogsport and Dr Paul McCrory of the British Journal of Sports Medicine. Various editors of other influential journals have also kindly allowed papers to be posted in our research section. Dr Patricios, in particular, acknowledges the contribution of Dr Mark Lovell and Dr Mickey Collins of the University of Pittsburgh Medical Centre, a beacon of excellence in concussion research, for their influence on concussion management and, as such, our programmes.

Sports Concussion South Africa appreciates that the field of sports concussion management is evolving and we will continue to seek further international exchanges and research opportunities to enhance the stature of the programmes available to South African sportspersons. As clinicians who deal with concussed athletes on the field and in the consulting room, we remain motivated in using education as our most powerful tool in keeping athletes from suffering from the potentially serious consequences of mild traumatic brain injury.
