The scapula has long been recognized as a key component in shoulder motion and a crucial part of the kinetic chain connecting the body's core and upper extremity. The pectoralis minor (PM) has garnered increasing attention as we better understand scapular kinematics and its role in shoulder pain and dysfunction. This is particularly important in patients with scapular dyskinesis and especially in overhead throwing athletes. The most of these patients achieve their recovery goals through nonoperative management, stretching, and strengthening protocols; however, some patients do not respond to nonoperative modalities. Several studies have recently shown improvement in shoulder motion and outcome scores after open surgical release of the PM from its scapular attachment. Arthroscopic release of the PM can be accomplished in the lateral decubitus position with standard shoulder arthroscopic portals.

EMG feedback improves force control of a myoelectric hand prosthesis by conveying the magnitude of the myoelectric signal back to the users via tactile stimulation. The present study aimed to test if this method can be used by a participant with a high-level amputation, and whose muscle used for prosthesis control (pectoralis major) was not intuitively related to hand function. Vibrotactile feedback was delivered to the participant's torso, while the control was tested using EMG from three different muscles.

Rupture of the pectoralis major muscle is extremely rare in adolescents. The current literature contains only 5 reports of this condition in patients under 20 years old, with 2 reports in subjects under 16. In the present article, we report the case of a 15-year-old volleyball player who suffered a traumatic rupture of the pectoralis major in a match during the serve movement.

Purpose: Poland syndrome is a congenital malformation characterized by agenesis or hypoplasia of pectoralis muscles. There is a limited literature on how the anatomic anomalies of PS may impact the movement of the shoulder. This study analyzes the effects of absence of the pectoralis muscles on the shoulder kinematic.

Purpose: To examine the acute effects of forehand drive (FD) preconditioning with or without blood-flow restriction (BFR) on subsequent forehand performance and muscle recruitment in tennis.
Methods: On separate visits, 12 well-trained tennis players participated in 4 randomized trials. Each visit included pretests (maximal muscle-activation capacity or FD performance), a preconditioning phase, and posttests after 5 minutes of rest (ie, similar to pretests).

This study aimed to investigate the effects of an 8-week lat pull-down resistance training program with joint instability on pull-up performance in male college students. Thirty-four healthy recreationally active male college students were randomly assigned to either the joint instability resistance training (IRT) or traditional resistance training (TRT) group. Participants of the TRT and IRT groups performed lat pull-down training on stable and joint instability conditions for 8 weeks, respectively.
