Grip Strength or Pinch Strength in Lateral Epicondylitis

Grip Strength or Pinch Strength: Which is Preferred to Evaluate Lateral Epicondylitis?

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.

Study Overview

• Status: Unknown
• Conditions: Lateral Epicondylitis

Detailed Description

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.
