Abstract

Athletes who repeatedly use the upper extremity to perform a task place high stress on the elbow, often resulting in medial or lateral joint injuries. The purpose of this study is to determine whether Ultrasound (US) or Low-level Laser Therapy (LLLT) is more effective in treating elbow pain and improving strength and range of motion (ROM). Twenty participants will be randomly assigned to either US (n=10) or LLLT (n=10) groups. Delayed-onset muscle soreness (DOMS) will be induced by maximal repetition bicep-curls, followed by eccentric lowering of a dumbbell from elbow flexion to extension, with twenty-seconds rest between three sets and forty seconds per exercise. Therapeutic modality based on the treatment group will be provided at 24 hours post-exercise. Measurements will be taken at 24 and 48 hours. RMANOVA will be used to determine significant difference between treatment groups. The US treatment is hypothesized to enhance blood flow, membrane permeability, and connective tissue response. However, this theory must be tested to determine a superior treatment.
