Injury incidence according to athlete impairment type during the 2012 and 2016 Summer Paralympic Games

Key words: Impairment, Para Sport, Injury, Paralympics, Summer, Para athlete

Injury surveillance in Para sport is an important part of Para athlete medical management. The underlying impairment type of each Para athlete requires an impairment-specific approach in order to successfully manage injuries. This blog summarises a recent publication investigating the incidence of injury according to athlete impairment type during the London 2012 and Rio 2016 Summer Paralympic Games, by sex, age, pre-vs competition period, and injury type, to inform bespoke injury management for Para athletes with different impairments (1).

Why is this study important?

The profiles of sport-related injuries in the Para sport population have been studied in and out of competition (2-9). However, studies investigating impairment-related injury risk factors are limited. 

Understanding the intricate relationship between an athlete’s impairment type, their sport discipline, and equipment utilisation is important. This study represents a pioneering effort as the largest impairment-specific investigation of Para athlete injuries to date. Results may contribute towards improving the quality of Para athlete research and injury prevention, comprising initial strides toward impairment-specific health management in Para sport.

How did the study go about this?

The injury data collected during the London 2012 and Rio 2016 Summer Paralympic Games were combined to form a database of 7222 athletes. Internet sources were used to identify the impairment types of all athletes that participated at the Games. To identify an athlete’s likelihood of sustaining an injury, injury rates and proportion were reported according to injury incidence per 1000 athlete days. Injury rates were reported for nine different impairment categories according to risk factors of: age (12–25 years, 26–34 years and 35+ years), sex (male or female), Games period (pre- vs competition), injury type (acute, repetitive, or gradual injuries) and area of injury (head, face and neck (HFN), upper limb (UL) mid-thoracic or lower limb (LL)). The impairment types of athletes were categorised according to athletes with brain disorders (BD), limb deficiency (LD), neuromuscular disorders (NMD), spinal cord-related disorders (SCRD), visual impairment (VI) and ’all others’ (OTH: impaired passive range of movement, intellectual impairment, leg length difference, short stature, and unidentifiable impairments).

What did the study find?

During the London 2012 and Rio 2016 Summer Paralympic Games, the incidence and type of injuries differed between athlete impairment types. Athletes with visual impairment had the highest incidence of injury, followed by athletes with neuromuscular disorders and spinal-cord related disorders. Athletes with limb deficiency had a moderate injury incidence, whilst athletes with brain disorders had the lowest incidence of injury. Acute injuries and injuries to the lower limb were common amongst athletes with visual impairment, while athletes with neuromuscular disorders had a higher incidence of repetitive injuries and injuries to the upper limb. In terms of sport, the athlete impairment category with the highest incidence of injury differed per sport (Figure 1).

What are the key take-home points?

Para athletes represent a heterogeneous athlete population group and managing the health of a Para athletes requires consideration of their underlying impairment type. During Summer Paralympic Games, athletes with visual impairment or neuromuscular disorders may be more susceptible to sustaining an injury compared to athletes of other impairment types. Clinicians and coaches should take note of the differences in the incidence, type, and area of injury for Para athletes with different impairment types, for better medical management of competition-related injuries in Para athletes.
