Knowledge, Motivation Behavior and Level of Physical Activity for Medical Students

Abstract

Introduction: Intense therapeutic ultrasound (ITU) is a newly established ultrasound-based, non-invasive therapy in which sound waves are concentrated and focused on musculoskeletal tissue for the purpose of pain reduction. This technology produces selective thermal coagulative changes over a small controlled area while leaving the surrounding tissue unaffected and without impacting the integrity of the dermis.Methods: A clinical study evaluating 29 patients (Age: 39 – 60, Male: 59%, Female 41%) for the effectiveness, safety and patient tolerance of Intense Therapeutic Ultrasound (ITU) for treatment of chronic (average length of symptoms prior to treatment: 12.9 Months), subcutaneous lateral Epicondylitis musculoskeletal tissue pain reduction was conducted. All patients enrolled in this IRB approved study had been previously diagnosed with Chronic Lateral Epicondylitis and had failed previous Standard-of-Care treatment regimen. Two ITU treatments were administered four weeks apart. Self-reported lateral elbow Universal Visual Analog pain scores and Patient-Rated Tennis Elbow Evaluation pain scores while performing normal daily tasks, were recorded pre-treatment (baseline measurement) and again at each follow-up time point - 4, 8, 12, and 26 weeks - after initial treatment. The goal for all subjects was to reduce overall pain and pain while performing everyday tasks by at least 25% on the average and more than 25% individually. While arbitrary, such criteria appear to be rigorous to reduce standard error and individual selfassessment variability.Results: Successful reduction of overall pain scores at 12 and 26 weeks following the first treatment are 88% and 82% of patients meeting the pain reduction criteria respectively. Also, at the same follow-up time points, patients reported an average VAS Pain Score reduction of 59% (Week 12) and 57% (Week 26) from a pre-treatment average of 5.08 down to an average of 2.2 at week 26. Additionally, patients reported an average pain reduction while performing everyday tasks of 58% and 61% respectively. Patient satisfaction remained over 80% for all follow-up dates.Conclusion: ITU is a promising non-invasive pain relief treatment for cases of chronic lateral epicondylitis.
