Abstract Details

2017, Master of Science, University of Toledo, Exercise Science.
Context: Non-contact elbow ligament sprains account for 8.1 percent of all baseball injuries reported in the NCAA. At the youth level, 68 percent of athletes report some type of medial elbow pain. The anterior bundle of the UCL is the area that most commonly fails with repetitive valgus stress seen with throwing. The flexor carpi ulnaris (FCU) and flexor digitorum superficialis (FDS) provide dynamic stabilization to the medial elbow during throwing. Identifying the activation of these muscles can allow clinicians to evaluate if the current progression utilized in rehabilitation is appropriate or not. Objective: To examine sEMG amplitudes of the FCU and FDS between 4 conditions of a UCL reconstruction rehabilitation progression. Design: Descriptive laboratory with crossover design. Setting: Laboratory. Participants: 16 healthy adult males. Inclusion: healthy with no upper extremity injury within the last three months, aged 18-30 years, 3 or more years of pitching experience since high school, 20/100 or less on the PREE. Exclusion: history of upper extremity surgery in the throwing arm and lack of palmaris longus in the throwing arm. Intervention: Participant will complete a plyometric exercise, long toss at 50 percent and 75 percent maximal speed, and a pitch. Main Outcome Measures: Video was assessed with 12 camera 3D analysis. sEMG data was assessed using a wireless sEMG system. Data was analyzed as means and peaks and were normalized to MVIC and a curve analysis was conducted. Results: The percent change of the FCU and FDS between long toss at 50 percent and 75 percent was significantly greater than the percent change between the plyometric exercise and long toss at 50 percent. Conclusion: For both muscles there was a significant increase in activation between the long toss at 50 percent and 75 percent which is indicative of an improper progression and would suggest the inclusion of a step placed in between the two conditions.
