The aim of the study was to develop a low cost, clinically easy to use measurement method with the Leap motion sensor for objectively evaluating range of motion (ROM), and to investigate the validity and reliability of this application.

. Wrist flexion / extension, radial / ulnar deviation, supination / pronation, 1.-5. of the fingers DIP, PIP and MCP flexion / extension ROM measurements will be made with universal goniometer and developed Leap motion sensor (LMC) based measurement method.

The study consists of two basic steps:

1. Development of measurement method with LMC Identification of normROM measurement procedure Identification of ROM measurement reporting Establishing the precursor version of the software of the measurement method Checking ROM measurement performance criteria and providing feedback Measuring the movement defined on 5 persons and providing feedback Creation of the last available version of the measurement method
2. Validity and reliability study Measurements of hand and wrist ROM with developed measurement method with LMC and universal goniometer for three times and calculation mean of three measurement for two methods

Inclusion Criteria:

• Healthy individuals

Exclusion Criteria:

• Have any hand/wrist problems between the ages of 18-40 years.
