ABSTRACT
Background@#Lateral epicondylalgia (LE) causes ineffective handgrip due to microtrauma on the elbow's common extensor origin. @*Objectives@#This study will determine the differences in the Extensor Digitorum Communis' (EDC) fascia slide, percentage maximum voluntary contraction (%MVC), static maximum handgrip strength (SMHGT), muscle activation onset time (MAOT) in LE and non-LE elbows, with and without Biomechanical Tape (BMT). The study will determine differences in Visual Analogue Scales (VAS) and Patient Rated Tennis Elbow Evaluation (PRTEE) scores of patients with and without BMT.@*Methods@#Nineteen participants' elbows with unilateral LE with and without BMT will be evaluated using musculoskeletal ultrasound (MSK) and electromyography (EMG) on Days 1, 3, and 5. A Physiotherapist-Sonographer, a Physiotherapist-EMG user, and a Research Assistant using Jamar hydraulic dynamometer will evaluate the participants. The participants will perform Mill's test during MSK and SMHGT using the dynamometer during EMG. A Chi-squared test will evaluate the relationship between BMT and fascia slide. Two-way repeated-measures ANOVA will compare the fascia slide, %MVC, SMHGT, and MAOT between elbows with and without BMT. It will be blocked according to elbow status (i.e., LE, no LE). Dunnett post hoc test will determine the groups whose results differed significantly. Differences in PRTEE scores at Days 1 and 5 will be determined. A p-value <0.05 indicates a significant difference in scores. @*Expected Results@#We expect decreased fascial slide measurements on EDC, VAS, PRTEE scores, and increased %MVC, MAOT, and SMHGT on taped elbows. Results will determine the underpinning mechanism behind the short-term effects of BMT.

ElectromyographyABSTRACT
Background and objectives: Lateral epicondylalgia or tennis elbow is a prevalent musculoskeletal disorder that is characterized by lateral elbow pain often associated with gripping tasks. This study was done to compare the effect of Mulligan’s mobilization with Mulligan’s taping and Diamond taping in chronic lateral epicondylitis grip strength. Methods: Forty (n=40) participants with chronic lateral epicondylitis were randomly allocated in two groups. Group ‘A’ received Mulligan’s mobilization with Mulligan’s taping and Group ‘B’ received Diamond taping and both the group received stretching exercise of the common extensors muscle of wrist prior to taping technique. The outcome measure was assessed in terms of Pain free grip strength (PFGS) for grip strength. Results: 20 subjects (n=20) were taken in both the groups with a mean age of 39.3 years in Mulligan’s Mobilization group and 41.95 years in Diamond taping group. Comparison of the pre and post values showed significant improvement (p<0.05) in grip strength in both the groups. When comparison of pre-test grip strength were done, there was no significant difference (p>0.05) in both the groups, this proves the fact that both the group started with the same intensity of grip strength while the post intervention comparison showed a significant improvement in grip strength (p<0.05) in both the groups. Conclusion: Mulligan’s Mobilization and Diamond taping intervention were equally beneficial in improvising the grip strength in patients with lateral epicondylitis.
ABSTRACT
Background@#Lateral epicondylalgia (LE) is a cumulative strain injury affecting the common extensor origin of the elbow, manifesting as lateral elbow pain. Tightness of the fascia connecting the lateral elbow area with the shoulder area was assumed as potential source of LE. Limitation in shoulder rotatory motions may be associated with painful LE elbows.@*Aim@#To determine the difference on shoulder rotatory motions between sides of symptomatic and asymptomatic elbows.@*Methods@#Eligible participants had at least one elbow that tested positive for Cozen, Mill, or Maudsley’s test. Using a universal goniometer, a blinded assessor measured the participants’ active and followed by passive shoulder internal and external rotation. The primary investigator tested the external rotation followed by internal rotation of the right upper extremity, then subsequently the left upper extremity of healthy participants both passively and actively@*Results@#The assessor showed excellent intra-tester reliability in measuring active and passive shoulder rotatory motions of 20 asymptomatic right upper extremities (ICC=0.98). Twenty-seven (27) participants (3 males, 24 females) with a mean (95%CI) age of 54 (49-58) years old were enrolled in the study. The mean visual analogue scale of the patients was 6.53 (5.91- 7.13), with mean (95%CI) duration of 96 (50-142) weeks. Based on hand dominance and side of LE, significant difference was found in active and passive shoulder internal rotation (p>0.05). @*Conclusion@#Shoulder active and passive internal rotations were significantly associated with hand dominance in patients with LE. Tightness of the fascia and muscle in the shoulder and painful LE elbow may underpin the decreased shoulder rotatory motions.
