Effects of Eccentric Tyler Twist Extensor-Strengthening Exercises in Lateral Epicondylitis

Background: Lateral epicondylitis, commonly known as tennis elbow, is characterized by pain and functional limitations at the elbow due to overuse. This study focuses on evaluating the effects of Tyler twist wrist extensor-strengthening exercises, aiming to provide insights into an effective intervention for this condition. Objective: This study aimed to determine the effects of Tyler twist wrist extensor strengthening exercises on pain, disability, and grip strength in patients with lateral epicondylitis. Methodology: A randomized controlled trial was conducted at Cina Medical Center Rawalpindi from February 2022 to January 2023. Fifty-two participants meeting the inclusion criteria were assigned to either Group A or Group B. Group A received eccentric Tyler twist exercises in addition to conventional physiotherapy, while Group B received conventional physiotherapy alone. Pain, functional disability, and grip strength were assessed at baseline, the second week, and the fourth week. Data was analyzed with SPSS version 25. Demographics and descriptive data is presented in form of percentages, frequencies and mean + SD. Normality of the data is determined via Shapiro Wilk Test. We applied mixed-way ANOVA to find the interaction between two groups. Results: Within-group analysis demonstrated a significant improvement in pain, functional disability, and grip strength for both groups (p-value < 0.01). Between-group analysis revealed a significant difference in pain, functional disability, and grip strength. Conclusion: The addition of eccentric Tyler twist exercises to conventional therapy showed a statistically significant difference in terms of pain, functional disability, and grip strength in patients with lateral epicondylitis.
