Many randomized controlled trials utilizing resistance training have shown improvements in muscle activation older adults. However, these programs lack applicability to community-dwelling adults due several challenges. Therefore, the purpose of this study was test effects an eight-week community-based program on Eight females (age: 61 ± 4 years, body mass index (BMI): 31.7 5.7 kg/m2) were enrol...

After apparently uncomplicated excision of benign lesions in the posterior cervical triangle, two patients had shoulder pain. In one, neck pain and trapezius weakness were not prominent until one month after surgery. Inability to elevate the arm above the horizontal without externally rotating it, and prominent scapular displacement on arm abduction, but not on forward pushing movements, highli...

[Purpose] This study investigated the effect of sleep posture on neck muscle activity. [Subjects and Methods] The study recruited 20 healthy subjects, who were positioned in three supine sleeping positions: both hands at sides, both hands on the chest, and dominant hand on the forehead. The activities of the scalene and upper trapezius muscles bilaterally were measured by surface electromyograp...

[Purpose] We investigated upper-extremity muscle activity during below-knee assembly work performed by healthy adults at three different reach distances evaluate the physical risk factors associated with neck and shoulder disorders of reach distances. [Subjects] Sixteen young male workers were recruited. [Methods] Activities of the right upper trapezius, anterior deltoid, and biceps brachii mus...

The goal of the present article is to compare neuromuscular activation patterns among medial-lateral, superior-inferior, and rotational positions palms for 14 selective muscles during push-up exercise. Muscle activity kinematics information fifteen males (68.35 ± 7.18 kg, 175 3.40 cm, 24.50 7.50 years) were recorded by Myon Electromyographic (EMG) system Vicon motion capture, respectively. EMG ...

Background:  Some studies show that frozen shoulder is due to the pathologic changes in the muscles around the shoulder. Measurement of the ultrasonic thickness of a muscle is a method for measuring the muscle changes. There is no study about the reliability of measurement of the muscle’s ultrasonic thickness around the shoulder in patients with frozen shoulder. The present study aims to invest...
