Aim. To determine the effects of vibration therapy devices exposure with a constant and aperiodic frequency of vibrations on the tissue of the biceps muscle of the shoulder. Material and methods. The study was conducted on 10 volunteers aged 24-35 years. the program Adobe Audition CC 2020, the device for vibration therapy with a constant vibration frequency “Charm 1-t”, the device for vibration therapy with an aperiodic vibration frequency “Individual massager with a pseudo-boiling layer” (MI EPS), the robotic biomechanical diagnostic and training complex with biological feedback CON-TREX were used. The measurement of the maximum strength of the biceps brachii muscle was carried out once to detect sensitivity to vibration, and then during 7 days for the dynamics of power characteristics. The maximum force was measured before exposure to vibrotherapy devices and immediately after exposure using the isokinetic classical mode of operation of the diagnostic system. Results. In a single measurement of biceps strength on one shoulder in a group of women, the average increase in muscle strength after using the Charm 1-T device was 0.8 N (2.3%), after using MI EPS – 1.9 N (6.4%). In the group of men, the average increase in muscle strength after using the device “Charm 1-T” was 1.9 N (3.2%), after using “MI EPS” – 4.6 N (7.2%). At the seven-day follow-up, the average increase in strength in the group of women on the right hand after using the Charm 1-T device was 21.8% (5.6 N), on the left hand after using MI EPS, the increase was 23.2% (6.1 N). In the group of men, the average increase in strength on the right hand after using “Charm 1-T” was 53% (30.7 N), on the left hand after using “MI EPS” – 15.5% (11.5 N). Conclusion. All participants in the study groups were determined to be sensitive to both types of vibration exposure. The study participants demonstrated an increase in strength indicators when testing the biceps muscle of the shoulder, and there was also an improvement in the tolerability of the procedure itself.

Abstract Context: Foam rolling has recently been used frequently to increase flexibility. However, its effects on proprioception, strength and motor performance are not well known. In addition, very few studies have examined the effects of foam rolling in the upper extremity. Objective: To investigate the effects of foam rolling on elbow proprioception, strength, and functional motor performance in healthy individuals. Design: Randomized controlled study. Setting: Exercise laboratory of X Department, X University. Patients or Other Participants: Sixty healthy participants (mean age=22.83±4.07 years). Intervention(s): We randomly assigned participants into two groups: the foam rolling group (FRG) (4 weeks of foam rolling for the biceps brachii muscle) and control group (CG) (no foam rolling). Main Outcome Measure(s): We evaluated proprioception (joint position sense [JPS] and force matching), biceps brachii muscle strength, and functional motor performance (modified pull-up test [MPUT], closed kinetic chain upper extremity stability test [CKCUEST], and push-up test) at the baseline, and at the end of the 4th week and 8th week. Results: JPS at 45° elbow flexion, muscle strength, CKCUEST, and push-up test results improved after foam rolling and improvement was maintained at the follow-up (p<0.017). While the changes in groups for the results of proprioception and CKCUEST were similar among the three time points (p>0.05), there were significant improvements for the muscle strength from baseline to the second evaluation, and from baseline to the follow-up (p<0.001) in the FRG compared to the CG (p=0.004). The FRG was superior to the CG in the improvement of push-up test results among the three time points (p=0.040, p=0.001, p<0.001). Other data did not change (p>0.05). Conclusion: Foam rolling is effective in improving elbow JPS in small flexion angles, biceps brachii strength, and some parameters of upper extremity functional motor performance. These effects are maintained 4 weeks after application.

AbstractThe coracobrachialis muscle (CBM) originates from the apex of the coracoid process, in common with the short head of the biceps brachii muscle, and from the intermuscular septum. The CBM demonstrates variability in both the proximal and distal attachment, with some extremely rare varieties, such as the coracobrachialis superior, coracobrachialis longus and coracocapsularis muscle. This case report describes an extremely rare variant of the coracobrachialis superior muscle, or a very rare variant of the CBM. Our findings highlight the importance of muscle variants in the shoulder region, especially the coracoid region, and are significant for radiologists, anatomists, physiotherapists and surgeons specializing in the shoulder joint.
