Flexor-extensor relationship knee after reconstruction of the anterior cruciate ligament

Introduction The incidence of knee injuries is very high in young adults. Anterior cruciate ligament (ACL) rupture is the most frequent of them. The isokinetic dynamometry evaluation determines the functional patterns of strength and muscle balance.Objective To compare the isokinetic hamstring/quadriceps peak torque and work ratios of young adults after surgical reconstruction of the anterior cruciate ligament.Methods We selected 33 medical records filed by the Isokinetic laboratory of the Physiotherapy Clinic of the Catholic University of Paraná (PUCPR), which belonged to patients who had undergone isokinetic assessment at the request of a physiotherapist or physician in Curitiba, Paraná. The tabulated data were: Hamstring/Quadriceps peak torque and work ratios of all injured and non-injured limbs at an angular velocity of 60°/s. Data were processed by the statistical software LHstat. Inferential statistics was used in order to apply the comparison test between means (unpaired t-test) with a confidence interval of 95%.Results The average flexion-extension ratio of the non-involved limb was lower than the involved limb both for peak torque (peak torque ratio of the non-involved limb: 56.1%; peak torque ratio of the involved limb: 66.3%; difference: 10.2%) and work (work ratio of the non-involved limb: 60.1%; work ratio of involved limb: 66.1%; difference: 6%).Conclusion : The average flexion/extension ratio found was adequate for both limbs and variables, however, the subjects presented a greater number of muscle asymmetries in the involved limb than in the non-involved limb.

“…The interest in assessing muscle performance of the knee extensors and flexors is due to the fact that they are reference values for the isokinetic and functional recovery progression and the return to sports (10,11). Isokinetic dynamometry is a reliable method of determining the functional pattern of muscle strength and balance.…”

“…A dinamometria de extensão de joelho é um importante instrumento na avaliação do desempenho de grupos musculares periféricos grandes e relativamente fortes, como o quadríceps femoral (VASCONCELOS, 2009). Além disso, é uma ferramenta que permite obter dados com alta confiabilidade intraexaminador e é considerável válida na detecção de déficits musculares (KAMIYA, 2015).…”

“…Looking toward alternatives, some studies have shown that dynamometers are a good option to replace the isokinetic dynamometer. Martin et al (2006) showed good agreement in the evaluation of the strength of the knee extensor musculature of geriatric patients, and Vasconcelos et al (2009) concluded that the analog isometric dynamometer adapted mechanotherapy equipment has the capacity of measuring the deficits of the flexor and extensor knee muscles. This research, nevertheless, point to a good reliability of isometric dynamometers to measure the strength of the lower limbs using evaluation of the knee joint, while no research that comes up with data about the reliability of hip adduction and abduction has been found (MARTIN et al, 2006;VASCONCELOS et al, 2009).…”

This study aimed to measure the reliability of a test for measuring the strength and strength imbalance of the hip abductors and adductors, using isokinetic equipment adapted for isometric testing. Thirteen healthy, physically active male individuals took part in the research. Two unilateral isometric tests were undertaken using a load cell attached to an adapted abductor bench machine: a hip abduction test and hip adduction test. Tests consisted of two maximum voluntary isometric contractions made for six seconds with a break of one minute between each. The following dynamic variables were measured: maximum force, mean force, rate of force development for each limb (right and left), and the existence of asymmetries between the limbs. For statistical analysis, the t-test, intraclass correlation coefficient (ICC), and standard error of measurement (SEM) were applied. Results: The methodology utilized for the evaluation of the hip abductors and adductors did not show reliability in most of the parameters researched, with the ICC neither sufficient or low, and the retest performance higher than the test (p < 0.05). The applied test was not reliable for assessing strength and strength imbalances of hip abductors and adductors in most of the parameters investigated. These results indicate that the hip joints, more precisely, the abductor and adductor muscles, are complex structures to be assessed. They need to be previously familiarized with the proposed exercise, as their performance does not occur habitually. It is recommended to develop new tests in order to measure hip abduction and adduction strength adding a prior familiarization procedure.
