Presentation Title
Shoulder Muscle Activation During Aerobic and Rehabilitative Exercise
Abstract
Background
Patients after elective orthopedic surgeries often experience post-operative weight gain. Weight gain can lead to debilitating and potential morbid diseases. Regular physical activity has been shown to reduce, or in some cases prevent weight gain. Typically, orthopedic protocols following shoulder surgery do not include physical activity recommendations. This is likely due to the lack of evidence regarding the safety of aerobic exercise following a surgical procedure. With an introduction to safe aerobic activity in a post-operative protocol, patients would be able to reduce the possibility of weight gain. The purpose of this study is to measure shoulder muscle activity, using electromyography (EMG), during a common rehabilitation exercise compared to aerobic exercises to analyze whether muscle activation during aerobic activity may be considered a safe implementation within a rehabilitation protocol.
Methods
Utilizing a cross-sectional study design, 30 healthy participants will be recruited aging from 18 to 50 years old. Exclusion criteria include a previous history of shoulder or cervical pain in the last 6 months. Participants undergo a single testing session utilizing surface EMG of shoulder muscles during 3 aerobic exercises and a rehabilitation exercise, pulleys. Using EMG SENIAM Guidelines, electrodes are placed on the upper trapezius, biceps, long head of triceps, middle deltoid, and infraspinatus. Maximal voluntary isolated contractions (MVIC) of each muscle are collected referencing the Muscles Testing and Function with Posture and Pain text for each of the manual muscle tests. The raw EMG data is filtered, smoothed, and normalized to the MVIC for each muscle. The mean EMG peak amplitude is analyzed to compare muscle recruitment during the pulley and aerobic exercises in conditions with and without a sling.
Results
Data has yet to be analyzed for results.
Conclusion/Implications
No data has been collected for discussion or conclusion.
