“…However, the absence of any significant joint kinematic differences between populations suggests the interpretation that athletic and nonathletic do not propel their daily wheelchair differently is valid. Additionally, an assumption of this work was that due to greater physical activity levels the athletic MWU will possess greater strength and physical capacity as shown previously (Freitas et al, 2019). However, no comparison of strength measures or muscle activity was undertaken.…”

The purpose of this study was to investigate whether athletic and nonathletic manual wheelchair users (MWU) display differences in kinetic and kinematic variables during daily wheelchair propulsion. Thirtynine manual wheelchair users (athletic n = 25; nonathletic n = 14) propelled their own daily living wheelchair on a roller ergometer at two submaximal speeds for three minutes (1.11 m s À1 and 1.67 m s À1 ). A 10 camera Vicon motion capture system (Vicon, Motion Systems Ltd. Oxford, United Kingdom) collected three-dimensional kinematics of the upper limbs and thorax at 200 Hz during the final minute of each propulsion trial. Kinetics, kinematics and kinematic variability were compared between athletic and nonathletic groups. Kinematic differences were investigated using statistical parametric mapping. Athletic MWU performed significantly greater physical activity per week compared to nonathletic MWU (920 ± 601 mins vs 380 ± 147 mins, respectively). However, no significant biomechanical differences between athletic and nonathletic MWU were observed during either propulsion speed. During the 1.11 m s À1 trial wheelchair users displayed a stroke frequency of 53 ± 12 pushes/min and a contact angle of 92.5 ± 16.2°. During the 1.67 m s À1 trial the mean stroke frequency was 64 ± 22 pushes/min and contact angle was 85.4 ± 13.6°. Despite the hand being unconstrained during the recovery phase the magnitude of joint kinematic variability was similar across both glenohumeral and scapulothoracic joints during recovery and push phases. To conclude, although athletic MWU participate in more physical activity per week they adopt similar strategies to propel their daily living wheelchair. Investigations of shoulder pain and dailywheelchair propulsion do not need to distinguish between athletic and nonathletic MWU.

Objetivo: Analisar o desempenho funcional e muscular da articulação glenoumeral de atletas do basquete em cadeira de rodas e comparar com atletas do basquete regular. Metodologia: Oito atletas do basquete em cadeira de rodas e oito atletas do basquete regular fizeram parte da amostra. Para a análise funcional, os testes realizados foram o maximal pass e o arremesso de medicine ball. Em seguida, foi realizada a avaliação do desempenho muscular dos músculos rotadores externos e internos do ombro, utilizando dinamômetro isocinético, no modo concêntrico-concêntrico nas velocidades angulares de 60º/s., 180º/s. e 240º/s. O teste t pareado foi utilizado para a comparação entre os membros e o teste t não pareado para a comparação entre os grupos. O teste de correlação de Spearman foi utilizado para verificar as correlações entre as variáveis funcionais e musculares. Foi considerado o nível de significância de p<0,05. Resultados: Não ocorreram diferenças estatisticamente significativas entre os grupos, tanto nas variáveis funcionais quanto nas musculares; assim como não existiram diferenças entre os membros nas análises de desempenho muscular. No entanto, correlações fortes e significativas foram encontradas entre o arremesso de medicine ball e os valores médios de pico de torque dos rotadores externos e internos do ombro (p<0,05). Conclusão: As fortes correlações entre o teste do arremesso de medicine ball e os valores médios de pico de torque sugerem que este teste funcional é uma ferramenta útil e pode ser considerada para a avaliação de desempenho muscular quando não é possível a utilização da dinamometria isocinética.
