      The validity and reliability of adduction angle measurement of hip with smartphone will be
      investigate.
    

Detailed description: 
      Our study is to investigate the intra-rater reliability, inter-rater reliability and
      concurrent validity of iPhone Measurement Applications to measure iliotibial band length in
      individuals without iliotibial band-related pathology. The aim of this study is to evaluate
      the intra-rater reliability, inter-rater reliability and concurrent validity of bubble
      inclinometer and iPhone Measurement Applications in the evaluation of iliotibial band tension
      in healthy individuals. This research is being done to determine if there are other more
      reliable, valid or innovative technological ways to measure iliotibial band length.

      Participants:

      A priori power analysis indicated that a minimum 16 or more participants should be enrolled
      the study for a correlation of 0.7, with an α level of .05 and power of 95%. The study
      protocol comply with the Declaration of Helsinki for Human Experimentation. Participants were
      excluded if they had hip or knee surgery in the past year and iliotibial band syndrome. All
      participants provide written informed consent. Permission for the study was obtained from KTO
      Karatay University Faculty of Medicine Drug and Non-Medical Device Research Ethics Committee
      with decision number 2019/012.

      Two experienced physiotherapists will evaluate the elasticity of both the dominant and
      non-dominant iliotibial bands after 2 minutes of warm-up before the evaluation. Measurements
      will be made by two physical therapists for each participant in different rooms without
      seeing each other. The examiners will carry out three measurements for both extremities,
      using both the bubble inclinometer and the iPhone® measurement app. A 5-minute passive rest
      will be give between measurements. All evaluations will be first conducted by Examiner 1 and
      then by Examiner 2. Measurement values will be record by a third physiotherapist. Data
      obtained from both devices will be compare in terms of validity and reliability using
      statistical analysis used in previous studies.

      All inclinometric measurements will be do by two independent blind examiners (B.S.U. and
      H.G.) and the range of motion (ROM) will be read directly from the devices by a third
      examiner.

      Before the first measurement, the participant will be ask to warm up for five minutes. For
      the measurement, the participant will be ask to lie on his side and flex the knee to 90
      degrees. The examiner will stabilize the patient from the pelvis with one hand, and with the
      other hand brought the flexed leg of the participant to abduction and extension. The Examiner
      3 will be record the result by placing the device to be measured on the lateral projection of
      the midpoint of the femur. By preserving the participant's position, measurements will be
      make with the other device immediately and the values will bw record by the Examiner3.

      After the first measurement, second and third measurements will be take at 2-minute passive
      intervals.

      After the participants will complete their first examiner evaluation, they will move to the
      second examiner's room. The same protocol will be use for all measurements by the Examiner 2.

      Instruments We will use 2 devices to measure iliotibial band length; bubble inclinometer
      (Baseline, Fabrication Enterprises Inc., New York) and iPhone® Measurement Applications
      (Apple Inc, California). The iPhone® Measurement Applications measurements will make with the
      iPhone 6s plus running IOS 13.3.1 (Apple Inc, California).
