Anterior cruciate ligament (ACL) injuries are among the most common and functionally disabling knee injuries, particularly in physically active individuals. Despite advancements in surgical techniques, optimal post-operative rehabilitation remains critical for successful functional recovery, minimizing re-injury risk, and restoring pre-injury performance levels
This randomized controlled trial aims to compare the effectiveness of perturbation training and task-oriented functional activities in patients following ACL reconstruction surgery. Perturbation training is a neuromuscular re-education strategy that involves controlled, unexpected movements to enhance joint stability and proprioceptive feedback. In contrast, task-oriented functional training focuses on restoring movement through activities that mimic daily or sports-related functional tasks. This study will be a Randomized Control Trail and will be conducted in physiogic physiotherapy clinic and Ghurki Trust and Teaching Hospital. Non-Probability Convenient Sampling will be used to collect data. Total of 54 Participants of the age 18-45 years with post 12 weeks to 1 year ACL reconstruction will be included in the study. An informed consent will be taken prior study from all the subjects. Outcomes measure will be included Numerical Pain Rating Scale (NPRS) for pain, Universal Goniometer (UG) for Range of Motion, Y balance test for Knee Stability, International Knee Documentation Committee scores, (IKDC) for Knee function

Two-leg rocker board One-leg rocker board Roller board / stable (weight scale) surface Roller board / BOSU ball TheraBand feedback / perturbation training Simple sport-specific technique on rocker board Moderate demand sport-specific technique on rocker board Advanced sport-specific technique on rocker board This sequence reflects a progressive challenge to knee stability, beginning with bilateral balance tasks, advancing to unilateral control, and culminating in sport-specific perturbation drills.
Functional Recovery Tasks After ACLR Normal walking gait Bilateral squat Unilateral foundation exercises - Single leg squat Bilateral landing Running - Run on treadmill Bilateral plyometric - Bilateral drop jump Unilateral landing / deceleration - Single leg deceleration Unilateral plyometric - Single leg drop jump Change of direction ability / coordination - 90º cut maneuver Sport-specific movements - Movement control under sport-specific change of direction This sequence reflects a progressive load and skill development pathway, starting from basic gait and bilateral tasks, moving toward unilateral control, plyometrics, and finally sport-specific agility.

RECRUITINGNPRS for Pain
Numeric Pain Rating Scale (NPRS) it is a unidimensional scale to measure pain intensity, particularly in adults. It is a 10-rating scale and an 11-point numeric scale in the form of a horizontal bar or line
Time frame: 6 weeks
Universal Goniometer for Range of motion
A universal goniometer (UG) will be used to determine the range of motion of the target joint.
Time frame: 6 weeks
The Y-Balance test (YBT)
The Y-Balance test (YBT) is used to assess dynamic balance impairments associated with lower extremity injuries such as ACL injury, patellofemoral pain syndrome, and ankle instability.
Time frame: 6 weeks
International Knee Documentation Committee scores (IKDC)
Patients' knee function is evaluated using the International Knee Documentation Committee's (IKDC) Subjective Knee Form. Through 18 questions, it assesses symptoms, athletic activity, and general knee function; higher scores indicate better knee function.
Time frame: 6 weeks
