Background: This paper aims to analyse the use of weight-throwing frames in Paralympic sport and their suitability for users, focusing on inconsistencies in frame design which
interfere with athletes’ performance.
Methods: Following a Work Ergonomic Analysis methodological approach, an analysis was made of some of the interdependencies between ergonomic inadequacies, modus operandi
requirements, and their impact on Paralympic athletes’ performance during the Rio de Janeiro Parapan American Games in 2007.
Results: Some of the ergonomic shortcomings found in frame indicated that they did not provide adequate sitting postures, reinforcing the fact that improvement in the athletes’
performance depends on a better interaction between athletes and frames.
Conclusions: It is concluded that the various dysfunctions that occur with weight-throwing frames during on-chair activities are factors that contribute to or even determine problems
related to the health and performance of Paralympic athletes.
