摘要

ResumoObjetivo Investigar, por meio do teste de reprodu??o da for?a, a existência de déficits proprioceptivos entre o membro lesionado e o n?o lesionado (i.e., contralateral normal) em indivíduos que tenham sofrido ruptura total de LCA. Métodos Participaram do estudo 16 pacientes com ruptura total do LCA. Foi feito o teste de for?a voluntária máxima isométrica (FVIM) e reprodu??o da for?a muscular no membro com ruptura total do {LCA} e contralateral saudável, com joelho a 60° de flex?o. Foi usada a intensidade‐meta para o procedimento de 20% da FVMI. O desempenho proprioceptivo foi determinado por meio dos valores de erro absoluto (EA), erro variável (EV) e erro constante (EC). Resultados Diferen?as significativas foram encontradas entre os grupos controle e {LCA} para as variáveis erro absoluto (p = 0,05) e erro constante (p = 0,01). N?o foi encontrada diferen?a para o erro variável (p = 0,83). Conclus?o Nossos dados corroboram a hipótese de existência de déficit proprioceptivo em sujeitos com ruptura total de {LCA} em um membro lesionado quando comparado com o n?o lesionado durante a avalia??o do senso da for?a. Esse déficit pode ser explicado por uma perda total ou parcial dos mecanorreceptores do LCA. AbstractObjective To investigate the existence of proprioceptive deficits between the injured limb and the uninjured (i.e. contralateral normal) limb, in individuals who suffered complete tearing of the anterior cruciate ligament (ACL), using a strength reproduction test. Methods Sixteen patients with complete tearing of the {ACL} participated in the study. A voluntary maximum isometric strength test was performed, with reproduction of the muscle strength in the limb with complete tearing of the {ACL} and the healthy contralateral limb, with the knee flexed at 60°. The meta‐intensity was used for the procedure of 20% of the voluntary maximum isometric strength. The proprioceptive performance was determined by means of absolute error, variable error and constant error values. Results Significant differences were found between the control group and {ACL} group for the variables of absolute error (p = 0.05) and constant error (p = 0.01). No difference was found in relation to variable error (p = 0.83). Conclusion Our data corroborate the hypothesis that there is a proprioceptive deficit in subjects with complete tearing of the {ACL} in an injured limb, in comparison with the uninjured limb, during evaluation of the sense of strength. This deficit can be explained in terms of partial or total loss of the mechanoreceptors of the ACL.
