Comparing the immediate effect of active stretching versus self-myofascial release on iliotibial band flexibility and functional activity in semi elite athletes
Evaluation of the immediate effect of active stretching techniques and self-release of myofascial tissue on the performance and flexibility of the iliotibial band in semi-professional athletes
Design
Clinical trial with three groups, with parallel groups, single blind, with random sequence by block randomization method on 51 patients. Random allocation software is used for randomization.
Settings and conduct
This is a clinical trial study that is performed in Shiraz School of Rehabilitation Sciences. Patients entered the study after signing the informed consent form and by using block randomization method are divided into three groups including PNF stretching technique group, foam roller group and combined foam roller therapy and PNF stretching technique group. The range of motion of hip adduction and the functional activities of patients are assessed before intervention and immediately after its completion. The study is single blind and evaluation and treatment are performed by two different physiotherapists and the evaluator is blind to the type of interventions performed.
Participants/Inclusion and exclusion criteria
Inclusion criteria: 20 to 40 years old semi-professional athletes, confirmation of unilateral or bilateral length reduction in iliotibial band by using modified Ober test.
Exclusion criteria: Having iliotibial band syndrome with pain or limping symptoms, history of surgery in the last three months in the lower limb, lower limb surgery more than twice, severe structural and postural disorders, neurological disorders
Intervention groups
group 1: using foam roller for 3 minutes
group 2: using Proprioceptive Neuromuscular Facilitation (PNF) for 3 to 5 minutes
group 3: Combination therapy of foam roller and PNF stretching technique
Main outcome variables
Hip adduction range of motion; Iliotibial band flexibility; Movement assessment

Randomization (investigator's opinion)
Randomized
Randomization description
In this study, the limited randomization method of block randomization will be used. Blockage is usually used to balance the number of samples allocated to each of the studied groups. The size of all the blocks is equal and in this trial which includes 51 patients in three groups, we will have blocks with size of 6. Random allocation software is also used for randomization. In order to conceal allocation of participants to the groups, sequentially numbered, sealed, opaque envelopes (SNOSE) will be used.
Blinding (investigator's opinion)
Single blinded
Blinding description
This study is single blind and the stages of evaluation and treatment are performed by two different physiotherapists and the evaluator is blind to the type of interventions performed and thus bias is prevented.

Intervention groups
1
Description
First intervention group: People using the hard model foam roller with dimensions of 60 by 15 cm by Behsazan Modern Company in one session. After learning how to use the foam roller, how to position during use and also the duration of using the foam roller to the participants, people are asked to lie on their side, then place the foam roller at the highest junction of the iliotibial band structures, slightly below the iliac crest. Individuals are asked to roll the foam roller towards the distal end of the iliotibial band junction at a constant speed and slowly by moving the body. The average speed of moving the foam roller is 5 movements per 30 seconds on average, and this speed is the same and constant in all people. Individuals are asked to do this slowly for three minutes.

Description
Second intervention group: People using Proprioceptive Neuromuscular Facilitation (PNF) stretching technique for 3 to 5 minutes in three steps. In the first step, the therapist gently moves the patient's limb from the hip joint to the end of the range of extension, adduction, and external rotation so that the iliotibial band at the end of the range is stretched. In the second stage, the patient is then asked to apply force in the direction of flexion, abduction and internal rotation by pressing his/her foot on the therapist's hand for 5 to 8 seconds. In the third step, the patient is then asked to relax his/her muscles again, and this time the therapist gently moves the patient's limbs to a new range of extension, adduction, and external rotation of the hip joint, and maintains traction by reaching the end of the range. These steps continue until there is no further increase in range of motion.
