Comparison of the effects of reactive neuromuscular training and traditional neuromuscular training on landing kinematics, balance, and performance of football players with anterior cruciate ligament reconstruction.
Investigating and comparing the effect of reactive and traditional neuromuscular exercises on landing kinematics, balance and performance of athletes with anterior cruciate ligament reconstruction
Design
Clinical trial with intervention and control groups, single-blind, randomized, on 30 individuals. Lottery will be used for randomization.
Settings and conduct
Study location: Faculty of Sport and Health Sciences; Study population:Soccer players with anterior cruciate ligament reconstruction;Type of blinding:One-sided blinding;Method of blinding:Training days of the groups were different.
Participants/Inclusion and exclusion criteria
Inclusion criteria:
Subjects should be football players with at least 3 years of professional sports experience;
Male players with anterior cruciate ligament reconstruction of superior leg (right);
People after 4 months after cruciate ligament surgery;
BMI between 18 and 25;
Reconstruction surgery on the anterior cruciate ligament with hamstring autograft;
Exclusion criteria:
injury in the opposite knee;
Insufficient range of motion of bending and extention the knee;
history of fracture or surgery of lower limb joints and postural disorders of lower limb, spine and soles;
history of balance disorders or vestibular system.
Intervention groups
Intervention group: Reactive neuromuscular training;
Control group: Traditional neuromuscular training.
Regarding the training protocols, it should be noted that both groups (traditional neuromuscular training and reactive neuromuscular training group) will perform both designed protocols (traditional and RNT), but with the difference that in the case of the RNT training protocol, the reactive neuromuscular training group will perform the exercises using a Traband, while in the conventional neuromuscular training group, the Traband will not be used.
Main outcome variables

Primary outcomes
1
Description
Angles of the knee and hip joints in the sagittal plane at initial contact and maximum knee flexion.
Timepoint
Before and after the intervention
Method of measurement
In order to investigate the kinematics of the knee, leg and thigh, the Vaikan motion analysis device with Bonita 10C cameras made in England with a sampling rate of 240 Hz will be used in the sports biomechanics laboratory of the Faculty of Sports and Health Sciences of Tehran University.
2
Description
Knee and hip joint angles in the frontal plane at initial contact and maximum knee flexion
Timepoint
Before and after the intervention
Method of measurement
In order to investigate the kinematics of the knee, leg and thigh, the Vaikan motion analysis device with Bonita 10C cameras made in England with a sampling rate of 240 Hz will be used in the sports biomechanics laboratory of the Faculty of Sports and Health Sciences of Tehran University.
3
Description
Angles of the knee and hip joints in the horizontal plane at initial contact and maximum knee flexion.
Timepoint
Before and after the intervention
Method of measurement
In order to investigate the kinematics of the knee, leg and thigh, the Vaikan motion analysis device with Bonita 10C cameras made in England with a sampling rate of 240 Hz will be used in the sports biomechanics laboratory of the Faculty of Sports and Health Sciences of Tehran University.
The Biodex balance test is used at stability level 12 as static balance, and scores obtained at stability level 4 are used for dynamic balance.

Intervention groups
1
Description
Intervention group: Theraband and mini-loop elastics will be used to perform reactive neuromuscular exercises; in this case, the trainer will increase the individual's incorrect movement pattern by using elastic bands and with a low load, and the exerciser will be asked not to allow the trainer to aggravate his movement inaccuracy. Theraband will be used in the single-leg squat, Romanian deadlift, standing lunges, single-leg squat on a bosu ball, and side squat assignments, and the mini-loop elastics will be used in the wall squat, kettlebell deadlift, and step up and down assignments.

Description
Control group: It should be noted that the control group will also perform both designed protocols (traditional and RNT), but with the difference that the Traband will not be used in the case of the conventional neuromuscular training group.
