Effects of Middle Trapezius, Lower Trapezius, and Serratus Anterior Strengthening on Pain and Functional Status in Lateral Epicondylalgia

Abstract

Background: Lateral Epicondylalgia (LE) is described as a tendinopathy at the common extensor origin at the lateral epicondyle of the humerus 1. Approximately 40% of people will experience LE at some point in their life. Recent studies highlighted the importance of assessing Middle Trapezius (MT), Lower Trapezius (LT) and Serratus Anterior (SA) muscle strength and also the importance of strength training in LE. CONTEXT AND PURPOSE: LE is the most common chronic musculoskeletal pain condition, causing significant pain, disability and lost productivity. Various studies focusing on scapular muscle strength and endurance give some indication that scapular muscle may need to be screened and treated. RESULT: There was significant effect on middle trapezius, lower trapezius and serratus anterior strengthening on reducing pain and improving functional status in patients with LE. CONCLUSION: The study primarily tried to analyze the effects of strengthening exercises to MT, LT, and SA along with conventional therapy on pain and functional status in LE patients. And this study reveals that addition of strengthening exercises to MT, LT and SA to the regimen enhances faster recovery in patients with LE. KEY WORDS: Lateral Epicondylalgia, Middle Trapezius, Lower Trapezius, Serratus Anterior.
