    Abstract

    Introduction: To investigate the effects of 12 weeks concentric-type isokinetic resistance training using two different angular velocities (120°/s and 240°/s) on isokinetic knee strength and functional ability of patients with chronic (more than three months post-trauma) grade 3 anterior cruciate ligament deficiencies. Materials and Methods: Nineteen male patients were included in the study. They were randomly assigned into three groups: control, 120°/s group and 240°/s group. The 120°/s intervention group (mean age: 36.8 ± 7.9 years) and 240°/s intervention group (mean age: 33.0 ± 11.4 years) participated in the prescribed training programme along with their existing conventional physiotherapy which were carried out twice a week. The control group (mean age: 33.5 ± 6.8 years) continued with their conventional physiotherapy only. Results: In all the groups, there was a significant improvement (p<0.05) in: (i) isokinetic peak torque after 6 weeks and 12 weeks of training periods; (ii) the International Knee Documentation Committee (IKDC) Subjective Knee scores after 12 weeks of training. Although not statistically significant, a trend of an increased knee peak torque and functional outcome was observed in the intervention groups when compared to the control group, with the 120°/s and 240°/s group showing the highest improvement in the isokinetic knee extension strength and knee flexion strength, respectively. Conclusions: Knee strength and physical functions improved in all three groups after 12 weeks of training, independently of the treatment applied. Rehabilitation is essential in the management of the chronic grade 3 anterior cruciate ligament deficient patients.
