A Comparative Study on Effect of Non-Ballistic Active Knee Extension in Neural Slump Position Versus Post Isometric Relaxation Techniques on Hamstring Flexibility in Sedentary Workers
Keywords:Non-Ballistic active knee extension, post isometric relaxation techniques, hamstring flexibility, sedentary workers.
Introduction: Flexibility is the ability to move single joint or series of joints smoothly and easily through an
unrestricted, pain free ROM. Adequate flexibility is an important characteristic of physical and health related
Objective: To find out the effect of Non-Ballistic Active Knee Extension in Neural Slump Position versus Post
Isometric Relaxation techniques on hamstring flexibility in sedentary workers assessed using Active Knee
Extension (AKE) test and Sit and Reach Flexibility test at the end of 3 weeks of intervention.
Methodology: The present experimental study was carried out in sedentary workers having hamstring tightness
(age group of 30 to 50) at musculoskeletal physiotherapy department at PES Moderna College of Physiotherapy,
Results: Majority of the patients in group A were from 36-40 years age group i.e. 14(31.1%). Majority of the
patients in group B were from 30-35 years age group i.e. 18(40%). Hamstring flexibility of right leg and left leg
are comparable at the end of 3 weeks. Post intervention hamstring flexibility using Sit and Reach in both legs are
comparable at the end of 3 weeks.
Conclusion: Both non-ballistic active knee extension in neural slump position versus post isometric relaxation
technique’s along with conventional treatment are equally effective in improving hamstring flexibility in sedentary
