Grip strength can be decreased in lateral epicondylitis. Pinch strength is also affected in people suffering from lateral epicondylitis. In this study, participants will be evaluated using a hydraulic dynamometer, a pinch meter and we will evaluate pain, disability and quality of life.

Newly diagnosed patients with lateral epicondylitis and healthy controls will be included in the study with an allocation ratio of 2:1. Using a hydraulic dynamometer grip strength will be evaluated three times, one minute between each measurement. Then palmar pinch, key pinch and tip pinch measurements will be evaluated for three times each. For each measurement, the participants will rest one minute between repetitive measurements, and five minutes between each parameters. The order of measurements will be randomized for each participants to avoid bias. Then the participants will be evaluated using different scales for pain, disability and quality of life.

Inclusion Criteria:

• Pain in elbow for at least two weeks

Exclusion Criteria:

• Nonsteroidal antiinflammatory drug usage during last week.
• Rheumatic diseases (Rheumatoid arthritis, systemic lupus erythematosus, reactive arthritis, etc.)
• Malignancy
• Extracorporeal shock wave therapy in last six months
• Lateral epicondylitis injection in last six months or any treatment.
• Lateral epicondylitis brace usage

Participants suffering from lateral epicondylitis will be included in the patient group and healthy control will be included in control group.
