Comparative Effects of Dynamic Stability Drills and Plyometric Training After Anterior Crutiate Ligament Reconstruction

Recruiting now · Not applicable

Conditions studied: Sports Physical Therapy

In brief

Terminal Extension lag (TEL) is a condition that develops when active range of extension is smaller than passive range; frequently noticed in post-traumatic knees after injuries and Anterior Cruciate ligament reconstruction surgery. TEL is typically seen within 6 to 12 weeks after ACL reconstruction. Anterior cruciate ligament reconstruction surgery is a critical surgical intervention used to repair ACL tear; which is common among those who are engaged in physical demanding activities and Sportsmen. In the initial days following surgery terminal extension lag affects up to 10 to 35% of individuals. ACL is expectational because it's not just a static stabilizer of knee but also transfers proprioceptive information to the brain so to improve joint's dynamics. This study aims to compare effects of Dynamic Stability Drills (DSD) and Plyometric Training (PT) in reducing terminal knee extension lag in post-ACL reconstruction patients. This study will be a Randomized Clinical Trail and will be conducted in Physiotherapy Department of Bethania Hospital Sialkot. Non-Probability Convenience Sampling will be used to collect data. Total of 48 Participants of the age 20 to 40 years with terminal extension lag of moderate lag stage (typically 9-12 weeks post-op with 5-10° lag) will be selected as sample size. An informed consent will be taken prior study from all the subjects. Outcomes measure will be included Numerical Pain Rating Scale (NPRS) for pain, Single Leg Hope Test and Y Balance Test (Y-BAL) for Dynamic Stability, Universal Goniometer (UG) for Range of Motion, Sphygmomanometer for Knee Strength, International Knee Documentation Committee scores, (IKDC) for Knee function and Limb Symmetry Index (LSI) Calculations. Subjects will be divided into two groups by random number generator table. Both groups will receive a standard physiotherapy protocols which will include: Hot pack , TENS , Mobilizations, Stretching and Strengthening. Group A will receive Dynamic Stability Drills and Group B will receive Plyometric Training along with conventional treatment. Patient will come 3 time a week and data will be recollected after 6 weeks. Data will be analyzed by SPSS version 25.
