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

Pakistan48 participantsStarted 2026-01-15

Plain-language summary

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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
