Randomization (investigator's opinion)
Randomized
Randomization description
Subjects will be divided into two control and treatment groups by the stratified randomization method, so the two groups will be balanced in terms of gender, and the process of this random division will be such that after creating blocks of 4 in each class (male gender and female) which consist of letters A and B, we will create a random sequence of these blocks using RANDOM NUMBER GENERATOR and the subjects will be placed in two control and treatment groups based on the order of reference by this sequence. The individual generating the randomization sequence will not participate in any other phase of the study.
Blinding (investigator's opinion)
Double blinded
Blinding description
In this study, the examiner or the person in charge of data collection and the one who evaluates the outcome and the subject or the participant will not know how the groups are divided. The examiner will not be present at the stage of dividing the subjects into treatment and control groups and the rest of the study stages. Also, the treatment that the subjects will receive in both groups will be apparently and look the same. In the treatment group, the subjects will receive preparatory treatments, therapeutic exercises and manual treatments in the form of the Mulligan technique, and in the control group, the subjects will receive preparatory treatments, therapeutic exercises and manual treatments in the form of the Mulligan technique in a simulated form; The method of performing this technique will be in such a way that no force will be applied to the place of handing after correct handing.

Intervention groups
1
Description
Intervention group: Intervention group: The participants in this group will receive10 treatment sessions during 4 weeks with at least one day between sessions by a therapist who is proficient in the Mulligan technique and regular physical therapy. The treatment in each group lasts for 60 minutes and includes 3 phases of preparation, exercise therapy and manual treatments. The first phase, preparation: in this phase, subjects will receive high-frequency electrical nerve surface stimulation for 20 minutes and infra red for 15 minutes. 4 electrodes are placed inside wet pads around the knee joint (two electrodes on the medial of the knee above and below the joint line and two electrodes on the lateral of the knee above and below the joint line) and will be tightened by the strap. The frequency and pulse duration used will be 110 Hz and 50 microseconds, respectively. The second phase, exercise therapy: The exercise therapy for these people will be in the form of strengthening exercises, stretching exercises, and range of motion exercises. Strengthening exercises include isotonic contraction with the help of varying leg weights of the knee extensor and hip abductor muscles, respectively, in sitting positions on the edge of the bed and lying on the side while the painful knee is elevated, with a frequency of 3 sessions per week according to the ability of the subject with The intensity of 60% to 80% of 1RM will include 2 to 4 sets of 8 to 15 sets, and between each set we will allocate 30 to 60 seconds of rest time to the subjects. We will use stretching exercises and active range exercises for muscle shortening or reducing the range of motion that disrupts the person's performance. Stretching exercises will be performed for 30 seconds in 3 sets of 10 for the biceps and hamstring muscles, and active and passive range of motion exercises will be performed in the form of movement from fully bent knee to fully straightened knee in 3 sets of 10. will get The third phase, manual treatments: At first, we will perform these exercises while lying on the back with the knees slightly bent. If the subject does not have pain in bending or straightening the knee while lying on the back, we will perform this technique for the subject while standing. gave Also, if after a few treatment sessions, the examiner does not have pain in bending and straightening his knee while lying on his back, we will follow the technique while standing. The treatment process will be like this, lying on the back with a slightly bent knee, we will ask the subject to actively bend and straighten the knee, then after placing hands around the knee joint, the subject's leg will be internally rotated, respectively. We will perform external rotation, internal glide, external glide, anterior glide and posterior glide and at the same time we will ask the subject to move his knee in the same painful direction and if the active movement of the subject that was painful before with any of the rotations or glides It was done without pain, we will use the same rotation or glide to continue the treatment. This technique should be performed without pain or with minimal pain, and if the pain decreases but does not reach zero, the therapist will reach a completely pain-free state by increasing or decreasing the applied pressure or applying additional pressure at the end of the range. This technique will be performed in the first session as a set of 6 and in the following sessions, according to the subject's ability, as 3 to 5 sets of 6 to 10. To perform the technique in a standing position, the subject will place the sole of the foot whose knee is painful on a stool at a height of 30 cm ; Then we will take active knee bending and straightening movements by applying internal and external rotations, internal and external glides, and anterior and posterior glides to the subject's leg. If the rotations do not hurt, we will continue the painful movement with the same rotation or glide for the subject.

All the mentioned steps, including the evaluation to find the glide or rotation with pain-free movement, as well as the part of performing the technique for the treatment, for the implementation of this technique in the treatment group, will be done exactly for the control group, and as it was said, the only difference will be this. It was that the glide or rotation in question will not be done in real way and no force will be applied and it will only be manual.
