Although the deltoid muscle has been assumed to be an essential shoulder muscle, the full extent of postoperative functions of the upper extremity following its complete resection due to sarcoma has not been thoroughly investigated. In this study, we review patients who underwent wide resection for sarcoma in the deltoid muscle, followed by functional reconstruction using pedicled latissimus dorsi (LD) muscle transfer. Four patients with sarcoma arising in the deltoid muscle were reviewed. Tumor resection with a wide surgical margin resulted in loss of the entire deltoid muscle together with the axillary nerve. For reconstruction, the ipsilateral pedicled LD muscle was transferred on its neurovascular pedicle for use as a functional substitute. One case had local recurrence and the transferred LD myocutaneous flap was resected. There were no serious complications after the operation, and all flaps survived perfectly. Wound healing at both the recipient and donor sites was uneventful. Active abduction of the shoulder joint was >160° in all patients. The muscle manual test of shoulder flexion was good to normal and abduction was fair to good. Musculoskeletal Tumor Society scores were excellent in all cases and the average score was 92% (range, 87-93%). Our results suggest that removal of the entire deltoid muscle resulted in a slight impairment of function. Pedicled LD musculocutaneous flaps are useful for covering the defect that results from resection of the deltoid muscle and they contribute additional function to the affected shoulder.

Background: Quadrilateral space syndrome is a painful disorder of the shoulder caused by static or dynamic entrapment of the axillary nerve and the posterior humeral circumflex artery. It was first described in 1983; however, it is an uncommon syndrome that initially presents with nonspecific shoulder pain or selective deltoid atrophy, and diagnosis is often delayed owing to its rarity. Young athletes of overhead sports are more commonly affected by this syndrome.

Introduction: During tasks like minimally invasive surgery (MIS), various factors can make working environment not be ergonomic, and those situations will accumulate fatigue in the surgeon's muscles which will inevitably lead to poor surgical performance. Therefore, there has been a need for technical solutions to solve this problem and one of the methods is exoskeleton robots.
Methods: We designed a passive shoulder exoskeleton whose workspace could be used for MIS to assist the surgeon's movements and performed computational and clinical validation.
Design of upper limb muscle strength assessment system based on surface electromyography signals and joint motion.

Purpose: This study aims to develop a assessment system for evaluating shoulder joint muscle strength in patients with varying degrees of upper limb injuries post-stroke, using surface electromyographic (sEMG) signals and joint motion data.
Methods: The assessment system includes modules for acquiring muscle electromyography (EMG) signals and joint motion data. The EMG signals from the anterior, middle, and posterior deltoid muscles were collected, filtered, and denoised to extract time-domain features.
How Does Blood-Flow Restriction Alter Forehand Drive Performance and Muscle Recruitment in Tennis Players?

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).
Eight-week lat pull-down resistance training with joint instability leads to superior pull-up endurance performance and reduced antagonist coactivation in recreationally active male college students.

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.
