About this study
Official title: Comparison of the Effects of Core Stabilization Exercises on Balance and Trunk Endurance in Individuals With Anterior Cruciate Ligament Reconstruction Surgery and Healthy Individuals.
The main purpose of this study is to evaluate and compare the effects of an 8-week core stabilization exercise program on balance, trunk muscle endurance, and lower body strength.
The study includes two groups of participants: 15 individuals who have had Anterior Cruciate Ligament (ACL) reconstruction surgery and 15 healthy individuals. Both groups will perform the same core stabilization exercises for 8 weeks, twice a week, under the supervision of a physiotherapist.
The goal is to determine if this exercise program improves balance and core strength in people who have had ACL surgery and to compare these results with those of healthy individuals performing the same exercises.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Core Stabilization Exercise ProgramBehavioural
Participants receive a supervised core stabilization exercise program for a duration of 8 weeks. Sessions are conducted twice per week by a physiotherapist. The program includes a set of standardized exercises such as the Hundreds, clam exercise, plank, side plank, dead bug exercise, curl-ups, and bridging.
| Study group | Role | What they receive |
|---|---|---|
| ACL Reconstruction Group | Experimental | Participants in this arm are individuals who have undergone unilateral Anterior Cruciate Ligament (ACL) reconstruction surgery within the last 5 years. These participants will receive a core stabilization exercise program for 8 weeks, with supervised sessions held twice per week. The exercise program includes movements such as the Hundreds, clam exercise, plank, side plank, dead bug, and bridging. Receives: Behavioral: Core Stabilization Exercise Program |
| Healthy Control Group | Active comparator | Participants in this arm are healthy individuals with no known history of lower extremity injury or surgery. This group is matched to the ACL Reconstruction Group. These participants will also receive the same core stabilization exercise program for 8 weeks, with supervised sessions held twice per week, to serve as a comparison group. Receives: Behavioral: Core Stabilization Exercise Program |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Dynamic Balance as Measured by the Y-Balance Test
The Y-Balance Test (YBT) is used to assess dynamic postural control. Participants stand on one leg at the center of a grid and reach with the other leg as far as possible in three directions: anterior, posteromedial, and posterolateral. The maximum reach distance in each direction is recorded in centimeters. A higher score indicates better dynamic balance.
Measured: Baseline and 8 weeks
Change in Trunk Muscle Endurance as Measured by the McGill Core Endurance Tests
Trunk muscle endurance is assessed using the McGill Core Endurance Test battery, which consists of four tests: a trunk flexor endurance test, a trunk extensor endurance test (Sorenson test), and right and left lateral trunk muscle endurance tests (side bridge). The time in seconds that a participant can hold each specific position without losing the correct form is recorded. A longer time indicates greater endurance.
Measured: Baseline and 8 weeks
