The effectiveness of Biomechanical Taping Technique on visual analogue scale, static maximum handgrip strength, and Patient Rated Tennis Elbow Evaluation of patients with lateral epicondylalgia: A cross-over study

Abstract

Introduction: Lateral epicondylalgia (LE) is a musculoskeletal injury involving the common extensor origin in elbow manifesting as pain and ineffective handgrip affecting the daily activities of the individuals with LE.

Objectives: This study determined the effectiveness of Standard Biomechanical Taping (SBMT), Vector Correcting Dysfunction Techniques 1 (VCDT 1) and Vector Correcting Dysfunction Technique 2 (VCDT 2); and compared their differences on effects on pain, grip strength and daily functions of individual with unilateral LE.

Methods: A cross-over study design was used. The senior investigator applied three BMT techniques namely: a. SBMT, b. VCDT 1, and c. VCDT 2. On Day 1, SBMT and VCDT1 were randomly assigned. On Day 3, either SBMT or VCDT1 not performed on Day 1 was applied to LE elbows. On Day 5, VCDT2 was applied on LE elbows. Visual Analogue Scale (VAS), Static Maximum Handgrip Strength Test (SMHGT) and Patient-Rated Tennis Elbow Evaluation (PRTEE) were used as outcome measures administered by three blinded junior investigators. On Days 1, 3, and 5, VAS and SMGHT were administered before and during BMT application. PRTEE was administered on Days 1 and 12.

Results: The following were found in this study: a. significantly decreased VAS scores at Days 1, 3, and 5 of BMT application (p < 0.05); b. significantly improved final VAS, SMHGT strength and PRTEE scores on Day 12 compared to baseline scores on Day 1 (p = /<0.01); and c. significantly decreased VAS scores when using SBMT compared to VCDT2 (p < 0.05).

Conclusion: BMT is a novel taping technique effective in decreasing lateral elbow pain, increasing handgrip strength and improving function of patients with LE. BMT can be applied on painful elbows effecting a better grip among patients with LE.
