Comparing the efficiency of ultrasound, ketoprofen, and mucopolysaccharide polysulfate phonophoresis in the treatment of lateral epicondylitis: A randomized-controlled clinical study

OBJECTIVES: In this study, we aimed to compare the efficiency of ultrasound, mucopolysaccharide polysulfate phonophoresis, ketoprofen phonophoresis and exercise combinations in terms of pain, functionality, disability, and strength in patients with lateral epicondylitis (LE). PATIENTS AND METHODS: This prospective, parallel-group, randomized-controlled clinical study included a total of 60 patients (42 males, 18 females; mean age 38.08 years; range, 21 to 50 years) with LE between April 2016 and October 2017. The patients were equally randomized into four groups based on the time of admission to the outpatient clinic. The Visual Analog Scale (VAS), painless weight lifting, the Patient- Rated Tennis Elbow Evaluation (PRTEE), and Quick Disabilities of Arm, Shoulder and Hand (QuickDASH) were used to measure the outcomes. The measurements were performed at baseline, at the end of 10 daily sessions, and after a six-week follow-up period. RESULTS: The resting VAS scores in the ketoprofen phonophoresis group and lifted weights in the MPS and ketoprofen phonophoresis groups showed a significant improvement both after 10 days of treatment and at six-week follow-up visits (p<0.001). In the QuickDASH model, there was no significant improvement in the control group after 10 days of treatment (p>0.05); however, a significant improvement was observed after six weeks (p<0.001). Except for these variables, significant improvements were found in all groups for all variables at six-week follow-up (p<0.05). However, improvements were similar in all groups (p>0.05). CONCLUSION: Based on our study results, for LE patients who are unable to adhere to exercise and splint use and are given a physical treatment plan, inclusion of ketoprofen and MPS phonophoresis in the treatment program may yield additional benefits in their daily living activities, functionality, and working life.
