Brief Summary

This study aims to evaluate the validity and reliability of the Dr. Goniometer application for measuring elbow flexion by comparing it with a manual goniometer. Conducted at Beykent University, the study will include 60 participants without upper extremity issues. Measurements will be taken on the dominant arm using both a manual goniometer and Dr. Goniometer, each repeated twice. Dr. Goniometer measurements will be performed twice by two different evaluators. Validity will be assessed using the Pearson correlation coefficient, while reliability will be evaluated with ICC and SEM. Measurement differences will be analyzed using a paired t-test. The results will contribute to determining the clinical applicability of the Dr. Goniometer application.

Outcome Measures

Primary Outcomes (1)

• Validity and Reliability of Dr. Goniometer in Elbow Flexion Measurements

  Comparison of elbow flexion range of motion measurements obtained using the Dr. Goniometer application and a universal goniometer to assess validity and reliability. Measurements will be taken by three independent raters, and intra-rater and inter-rater reliability will be analyzed using ICC and SEM. Pearson correlation will be used to determine validity.

  Baseline

Study Arms (1)

Elbow Flexion Measurement Group

Participants in this group will undergo elbow flexion range of motion (ROM) assessment using both a manual goniometer and the Dr. Goniometer application. Each participant's measurements will be taken twice. The measurements will be conducted twice by two different evaluators, and the average values will be analyzed to determine the validity and reliability of the Dr. Goniometer application compared to the manual goniometer.

Other: Dr. Goniometer Application

Interventions

Dr. Goniometer Application OTHER

The Dr. Goniometer application is a digital tool used for measuring elbow flexion range of motion (ROM). In this study, participants' elbow flexion ROM will be assessed using both the Dr. Goniometer application and a manual goniometer. Measurements will be taken twice by two different raters to evaluate the validity and reliability of the digital application compared to the manual goniometer.
