Effect of Theraband Flex Bar and Strengthening Exercise in Patients with Lateral Epicondylitis After Phonophoresis Intervention

Abstract Background:
Lateral epicondylitis, commonly known as tennis elbow, is a degenerative tendinopathy affecting the common extensor tendon of the elbow, particularly the extensor carpi radialis brevis. It is characterized by pain, reduced grip strength, and functional disability, commonly resulting from repetitive wrist extension and gripping activities. Conservative physiotherapy interventions, including eccentric strengthening and electrophysical agents, have shown promising outcomes in rehabilitation.

Aim:
To evaluate the effectiveness of Theraband Flex Bar exercises combined with eccentric strengthening exercises compared to conventional strengthening exercises in patients with lateral epicondylitis following phonophoresis intervention.

Methodology:
A randomized controlled trial was conducted on 30 participants diagnosed with lateral epicondylitis, aged between 30–50 years. Participants were randomly allocated into two groups: Group A received Theraband Flex Bar exercises combined with eccentric strengthening, while Group B received conventional strengthening exercises. Both groups initially underwent phonophoresis using therapeutic ultrasound with diclofenac sodium gel. The intervention lasted for 4 weeks with 3 sessions per week. Outcome measures included Visual Analogue Scale (VAS) for pain, grip strength measured using a hand dynamometer, and Patient-Rated Tennis Elbow Evaluation (PRTEE) for functional disability.

Results:
Both groups demonstrated statistically significant improvements in pain, grip strength, and functional ability following intervention (p<0.001). Group A showed greater improvement compared to Group B across all outcome measures. Pain intensity was reduced by 69.1% in Group A and 44.9% in Group B. PRTEE scores improved by 60.6% in Group A compared to 40.5% in Group B. Grip strength increased by 50.6% in Group A and 41.9% in Group B.

Conclusion:
Both intervention protocols were effective in managing lateral epicondylitis; however, Theraband Flex Bar exercises combined with eccentric strengthening following phonophoresis demonstrated superior effectiveness in reducing pain and improving functional disability. The findings suggest that incorporating eccentric elastic resistance training with phonophoresis may provide enhanced clinical benefits in the rehabilitation of patients with lateral epicondylitis.
