| description | Background: Ligament injury accounts for nearly 40% of all injury problems in anterior cruciate ligament injury constitute nearly 50% of all knee ligament injuries. Anterior cruciate ligament deficiency affects not only the mobility, self-confidence and lifestyle of the affected persons in short term but also causes arithmetic changes in the affected knee in the long run. Purpose of study to find the effectiveness of concentric and eccentric for post anterior cruciate ligament reconstruction subjects on muscle strength, joint range of motion and pain.
Methods: 24 samples with age group of 35 years were randomly assigned to two groups Concentric and Eccentric groups. The Concentric group, performed 9 (3sets) concentric contractions for knee extensors and 9 concentric contractions for knee flexor muscles. The eccentric group done 9 (3 sets) eccentric contractions for knee extensors and 9 eccentric contractions for knee flexors.
Results: Pain is significantly decreased in concentric group. But not significantly decreased in eccentric group (t = 2.85, P = 0.009; and t = 1.40; P = 0.17). The range of motion is significantly increased in both concentric knee extension and flexion and eccentric knee extension and flexion (t = 3.53, P = 0.0023; and t = 4.55; P < 0.001). The quadriceps muscle strength is significantly improved in both concentric and eccentric groups at 60° / sec and 90° / sec.
Conclusion: The eccentric exercises are better than concentric exercises in improving the strength of hamstring and quadriceps muscles. |
