Ultrasonographische Bestimmung von Interventionseffekten auf die Muskelarchitektur-Charakteristik der Rotatorenmanschette
Projektbeschreibung
The rotator cuff muscles-RCM- (supraspinatus muscle, infraspinatus muscle, subscapularis muscle and teres minor muscle) have been shown to be substantial dynamic stabilizer of the glenohumeral joint in multiple shoulder positions. Thus, our knowledge of anatomy, biomechanics and function of this specific musculature is critical in an attempt to develop the most advantageous rehabilitation programs. Several investigations have sought to describe common rehabilitation exercises using kinematics, kinetics and EMG (electromyographic) data to better understand the implications of each exercise on the soft tissues around the glenohumeral joint. An overview of the available literature has been recommended a proper selection of exercises to activate RCM function appropriate for rehabilitation and prevention of the glenohumeral joint surrounding structures.
The main objective of this study will be to investigate changes in rotator muscles architecture characteristics with ultrasound imaging, after exercises for glenohumeral joint stabilizing structures as the RCM
40 participants-male and female- (aged 18-25 years) with no RCM- or other shoulder injuries and no completive sports activities will be involved in this study. They will be classified into three groups following RCM exercises. The first one (A) will follow supraspinatus exercises (full can and prone full can), the second (B) infraspinatus muscle and teres minor muscle (side line external rotation-ER- and prone ER at 900 adbuction) and the third one (C) subscapularis muscle exercises (internal rotation-IR-00 adbuction and IR at 900 adbuction). The program will be lasted 8 weeks, 3 times per week, performing 20 repetitions each exercise, with 1 kg free weight for female and 2 kg weight for male. The speed of the repetitions will be regulated by a metronome.
They will be evaluated with ultrasound imaging of RCM muscle architecture characteristics (muscle thickness, size, width, length, cross-section-area - CSA) before and 8 weeks after the exercises program. Thus, these results will be analysed by repeated measures analysis of variance.
