Palpation of the Ileotibial Band Tension
Detection of the Ileotibial Band Tension Through Direct Palpation: a Reliability Assessment Study
The goal of this clinical-test study is to evaluate the reliability of the direct palpation of the ileotibial band. For this purpose, a group of 100 healthy subjects will be considered. The main question it aims to answer regards the reproducibility of the intra and inter examiner evaluation performed on the same day (intra-day) and the validation of the palpatory examination with an instrumental measure of the tissue tension.
Participants will undergo a manual and instrumental sampling of the ileotibial band tension of both legs.

Detailed Description
The project includes 6 phases:
I phase - agreement in principle on the method of collection; II phase - recruitment; III phase - first sampling; IV phase - training on perception and concordance; V phase - second sampling to verify the progression of the agreement; VI phase - third manual sampling and evaluation with Myoton.
Description of the phases
Phase I - Two examiners together with the principal investigator perform 2 hours of training to standardize the sampling method (localization of the point to be evaluated of the Iileotibial band -ITB- and intensity of pressure of the fingertips to be used) and discussion on the tension gradation detected on the ITB with some volunteers.
Phase II - The recruitment will be carried out through the search for volunteers among the students of the OSCE-Bologna school of osteopathy, through announcement in the classroom and publication of the recruitment in the FB social group of the school (OSCE planet) and WhatsApp groups of students organized by year .
Phase III - First sampling of manual evaluation only, using a sample of 40 subjects (both limbs), as proposed in the literature.
The detection is to identify if there is an equal or different stiffness between the right and left ITB.
The transcript of the discovery will be double for each sampling session: 1) the first will report whether there is a uniformity of the tension between the two sides, or if there is a prevalence on one side; the second will try to quantify, in case there is a difference between the two sides, with a graduation of 3 levels of the difference.
In the first survey, the examiner will indicate a higher tension on the right side with +1; - 1 on the left side; 0 if there are no significant differences.
The second detection is to identify, when present, the graduation of the stiffness difference between the two sides, arbitrarily divided into 3 levels. The examiner, therefore, will report:
- 3 to indicate greater tension on the right with a large difference from the left;
- 2 to indicate a higher tension on the right with an average difference compared to the left;
1 to indicate greater tension on the right with a slight difference from the left; 0 to indicate a non-appreciable prevalence of tension on one side over the other;
- 3 to indicate greater tension on the left with a large difference compared to the right;
- 2 to indicate a greater tension on the left with an average difference compared to the right;
- 1 to indicate more tension on the left with a slight difference from the right.
IV phase - The manual examiners carry out a training period on perception and concordance, lasting about 20 hours. This training is carried out using instruments (gold standard) made specifically to modify the state of stiffness of elastic structures and strings that simulate the ITB, connected to dynamometers to measure the amount of stiffness. In vivo evaluation, among the operators, are used to verify the exact positioning where to perform the stiffness sampling and compare the tension data obtained for the construction of the agreement.
V phase - The second sampling to verify the progression of the manual agreement, as proposed in the literature, is carried out by evaluating the stiffness of the ITB, in the same way as for the first sampling with volunteers, but in a reduced sample (about 20 subjects). If the statistical processing of the results of this test evaluation shows a good level in the agreement (Cohen K > 0.60), the definitive sampling is scheduled at a later date; otherwise you return to training by increasing the hours.
VI phase - The definitive manual sampling consists in repeating, using the same method of the first evaluation (baseline), with different or identical subjects of the first sampling. The number of subjects will always be 40, evaluated by both examiners and each examiner will evaluate the same subject twice at a distance of about 20-60 minutes. The same subjects will be tested, after the manual evaluation, with the Myoton using the modality previously described. The Myoton results are automatically stored in the preset instrument with the subject's ID and can be downloaded to the computer in an Excel worksheet.
All the data obtained is collected and processed by the examiner who does not participate directly in the data collection using an Excel spreadsheet and / or the R program.

Description
Inclusion Criteria:
- healthy subjects
Exclusion Criteria:
- clinically evident painful symptoms that, in the opinion of the subject himself or the examiner, may prevent the test from being carried out (for example, pain in the hip while maintaining the sampling position);
- evident excess weight (BMI greater than 28 kg / m2) which may make the manual and instrumental result obtained doubtful.

Evaluation of how a dedicated training / agreement can modify the level of agreement between intra and inter examiner, by means of weighted Cohen's K with use of sampling evaluation divided into 3 intervals (+1, 0, -1) and 7 intervals (+3, +2, +1, 0, -1, -2, -3)

Accuracy of the palpation test
Time Frame: 5 seconds for each evaluation (day 1)
|
Concordance intra-day between the manual and instrument evaluation.
The instrumental data are processed by subtracting the average data of the three measurements (automatically carried out by the instrument) of the right limb from that of the left.
The data obtained is categorized into 3 levels to be compared, again using weighted Cohen's K, with the data from the manual evaluation.
