Análise do tempo de desenvolvimento de torque no pré-operatório de pacientes com lesão do ligamento cruzado anterior

Abstract

Introduction: The gain in muscle strength and knee stability in the preoperative period are of fundamental importance for a quicker, safer and unrestricted return to sports activities. In this sense, effective rehabilitation is needed to assess muscle performance with objective criteria, thereby avoiding postoperative complications. Objective: Analyse through isokinetic evaluation of time to peak torque muscle performance of patients with ACL injury on the preoperative period. Methods: Were evaluated 17 subjects practioners of recreational sport activity with ACL injury treated by physiotherapy preoperatively. For evaluation of muscle performance the variables peak torque and time to peak torque were analyzed using the isokinetic dynamometer Biodex System 3 Pro ® at speed of 60º/s for comparison between healthy and injured members. Results: From the initial sample only 15 subjects were considered. Through the dependent t-test it was concluded that the differences between healthy and injured members during extension and flexion were not statistically significant. The analysis of correlations between time to peak torque and peak torque resulted in three significant cases. Conclusion: The time to peak torque can not be considered an objective variable to assess the preoperative recovery and thus can not report whether there are conditions suitable for submission to ACL reconstruction surgery.
