BACKGROUND: Strengthening the infraspinatus is important in shoulder rehabilitation. Changes in infraspinatus activity with changing load and position have not been quantified. We sought to determine the most appropriate load and posture for early infraspinatus strengthening by assessing for changes in electromyographic activity in the healthy infraspinatus and other shoulder girdle muscles during isometric external rotational exercise under different loads with the shoulder adducted in the supine and seated positions...

Background: Polymyalgia rheumatica (PMR) is a common systemic inflammatory disease of the elderly; however, the clinical characteristics and therapeutic response of PMR in Korea have been rarely studied. Methods: We reviewed the medical records of 54 Korean patients diagnosed with PMR between January 2009 and February 2017 in a locomotive pain clinic of one tertiary referral hospital. We analyzed epidemiologic and clinical characteristics, therapeutic responses, and prognostic factors for remission-failure at one-year after oral prednisolone treatment...

Da-Ye Kim, Jae Min Kim
Myofascial pain syndrome is a common painful condition encountered in the general population. Previous studies evaluating the efficacy of botulinum toxin for the treatment of myofascial pain syndrome are limited, with variable results. This prospective study investigated the efficacy and safety of direct injection of Prabotulinumtoxin A (Nabota® ) into painful muscle groups for cervical and shoulder girdle myofascial pain. Twelve patients with chronic myofascial pain syndrome of the neck and shoulder underwent an injection of Prabotulinumtoxin A...

As the number of people suffering from shoulder movement disabilities increases, there is a rising demand for shoulder rehabilitation. The natural motion of the shoulder joint [glenohumeral (GH) joint] includes not only three-degrees-of-freedom (DOF) rotation but also three-DOF translation of the joint center due to simultaneous motion of the shoulder girdle. If the motion of the shoulder girdle is restricted, then the arm cannot be raised above a certain posture. This paper presents a passive shoulder joint tracking device that allows three-DOF translation of the shoulder joint while compensating for gravity...

Shoulders of elite field hockey players are loaded continuously during play. However, shoulder girdle muscle performance in this population has never been examined yet. This study aimed to compare isokinetic shoulder girdle performance in elite male field hockey players to matched controls, with respect to strength, endurance and muscle balance. The complete male national field hockey team of Belgium (n = 25) was included and matched to a gender- and age-matched control group of healthy participants (n = 25)...

Transarterial embolization of bone tumors is effective in both decreasing intraoperative hemorrhage and alleviating symptoms. Transradial access has been associated with a lower risk of access site complications when compared to transfemoral access. Three cases of transarterial embolization of bony metastases in the upper extremity and shoulder girdle were performed with an ipsilateral transradial access. In each case, significant decrease in tumor blush was noted after embolization, and no auxiliary access site was needed...

REVIEW
Thomas W P Wood, Tetsuya Nakamura
The fish-to-tetrapod transition is one of the fundamental problems in evolutionary biology. A significant amount of paleontological data has revealed the morphological trajectories of skeletons, such as those of the skull, vertebrae, and appendages in vertebrate history. Shifts in bone differentiation, from dermal to endochondral bones, are key to explaining skeletal transformations during the transition from water to land. However, the genetic underpinnings underlying the evolution of dermal and endochondral bones are largely missing...

Objectives: Lower limb isometric tests are used to assess strength and strength asymmetries and monitor reductions in muscle force that may contribute to loss of performance and increase injury risk. Isometric tests in the upper body may be appropriate to monitor neuromuscular performance of the shoulder joint in sports involving contact and overhead actions. The aim of this study was to determine the reliability of a novel upper body isometric strength test. Methods: Eighteen elite rugby players (age 22...

The use of the da Vinci robot in minimal invasive surgery comes with numerous advantages. Recent papers describe improvements in the ergonomic environment and benefits for the surgeon's posture in the console. Ergonomics for first assistants or scrub nurses at the OR table during robot-assisted procedures, however, have gained minor attention. The aim of this study, therefore, is to analyse the ergonomic environment specifically for first assistants during robot-assisted surgery. Three techniques were used to evaluate body posture and ergonomics during three discriminated actions...

Injury of the acromioclavicular joint (AC joint) is one of the most common conditions affecting the shoulder girdle in athletes, particularly in contact sports. It is generally agreed that surgical management provides superior outcomes in high-grade injuries (Rockwell Grades IV-VI), with nonoperative management preferred in low-grade injuries (Grades I-II). Controversy still exists regarding the optimal treatment for Grade III injuries, with various sources reporting quicker return to activity and reduced complications with nonoperative management, but superior long-term function and satisfaction in cases managed surgically...

Fournier's gangrene is a rare, high-mortality infection that affects the subcutaneous tissue with rapidly progressive necrosis. The objective is to report a case of Fournier's gangrene involving the region of the shoulder girdle after closed fracture of the clavicle, and to discuss this unusual evolution. The patient underwent a series of surgical procedures and was followed up on an outpatient basis for 12 months, at which point she was discharged. Fournier's gangrene is an aggressive lesion and requires early diagnosis (clinical-laboratory correlation) with the appropriate adequate surgical approach and clinical stabilization...

After a stroke in middle cerebral artery territory, there is a high probability of dysfunction of the ventromedial pathways, mainly related with postural control mechanisms such as the anticipatory postural adjustments (APAs). According to neuroanatomical knowledge, these pathways have a predominant ipsilesional disposition, which justifies a bilateral postural control dysfunction, often neglected in rehabilitation. In order to assess this bilateral postural control dysfunction, electromyography activity was assessed in eight post-stroke and 10 healthy individuals in the anterior deltoids, the superior and lower trapezius, and the latissimus dorsi as they reached for a bottle with both upper limbs separately at a self-selected velocity and fast velocity while standing associated with trunk kinematics analysis...

OBJECTIVE: An observational cross-sectional study was conducted in a national facioscapulohumeral muscular dystrophy (FSHD) expertise center to estimate the penetrance of FSHD1 and to evaluate phenotype-genotype correlations. METHODS: Ten FSHD1 probands carrying 4-9 D4Z4 unit alleles and 140 relatives were examined. All 150 participants were genetically characterized, including D4Z4 methylation levels in the mutation carriers. Mutation carriers were classified as (1) symptomatic: with symptoms of muscle weakness on history and muscle FSHD signs on examination; (2) asymptomatic: without symptoms of muscle weakness but with muscle FSHD signs on examination; and (3) nonpenetrant: without symptoms of muscle weakness on history and without muscle FSHD signs on examination...

Dear Editor, Syphilis is an infection caused by Treponema pallidum. Without treatment, it goes through the following stages: primary, secondary, latent, and tertiary (1). The clinical picture of secondary syphilis is very variable (2,3). We present two rare cases of secondary syphilis, one with nodular lesions initially considered to be lymphoma and second with periostitis, which was initially interpreted as an osteoma. To date, only 15 cases with nodular lesions and 10 cases with periostitis in secondary syphilis have been reported in the literature...

The authors made an attempt to highlight the issues of rehabilitation of the patients suffering wounds in the maxillofacial region with the concomitant disorders in the function of the organs of speech. The secondary objective of the study was to prove that rehabilitation of such patients is possible only by means of the joint efforts and close cooperation of dentists, physiotherapists, and speech therapists. The results of the clinical observations of the most severe cases of the impaired speech function obtained in the evacuation hospitals have been considered, with the special emphasis placed on the leading role of the speech therapist in the rehabilitation of such patients...

Subscapular abscess is an uncommon condition which requires early recognition followed by prompt surgical intervention. We present a case of spontaneous subscapular abscess following blunt trauma to the shoulder in a patient with a history of recurrent superficial soft tissue infections, in which Panton-Valentine leukocidin-producing S. aureus was identified as the infectious agent. This strain due to its virulence can lead to fatal infections in otherwise healthy individuals; therefore, a high index of suspicion is needed to investigate with an MRI to rule out abscess formation in a patient with acute shoulder girdle pain and negative joint aspirate...

During a dive, peregrine falcons (Falco peregrinus) can reach a velocity of up to 320 km h- 1 . Our computational fluid dynamics simulations show that the forces that pull on the wings of a diving peregrine can reach up to three times the falcon's body mass at a stoop velocity of 80 m s- 1 (288 km h- 1 ). Since the bones of the wings and the shoulder girdle of a diving peregrine falcon experience large mechanical forces, we investigated these bones. For comparison, we also investigated the corresponding bones in European kestrels (Falco tinnunculus), sparrow hawks (Accipiter nisus) and pigeons (Columba livia domestica)...

This case describes a 16-year-old boy who suffered a severe traumatic brain injury. The patient gradually recovered but developed debilitating spasticity mainly in left triceps muscle, abnormal positioning of shoulder girdle complex, and shoulder pain. Phenol (6%) was injected to axillary and radial nerves under guidance of electrical stimulation and ultrasound imaging at 10 weeks after initial injury. After injection, triceps spasticity and shoulder pain was immediately reduced and abnormal positions of shoulder girdle complex and elbow joint gradually returned to functional limits over 2 weeks...
