Rana Soltani-Zarrin, Amin Zeiaee, Reza Langari, Nina Robson
This paper proposes a reference path generation method for upper-limb rehabilitation exoskeletons considering the scapulohumeral rhythms of the shoulder. The developed method is based on Central Nervous System's (CNS) governing rules for coordination of arm motions, and to the best of our knowledge is the first computational model to consider the motion of the inner shoulder in path generation. Existing reference generation methods which utilize computational models such as minimum jerk, minimum torque, etc, are based on the assumption that the shoulder joint does not move, and the origin of the reference frame is defined at the center of the glenohumeral (GH) joint...

Targeted muscle reinnervation (TMR) represents a breakthrough interface for prosthetic control in high-level upper-limb amputees. However, clinically, it is still limited to the direct motion-wise control restricted by the number of reinnervation sites. Pattern recognition may overcome this limitation. Previous studies on EMG classification in TMR patients experienced with myocontrol have shown greater accuracy when using high-density (HD) recordings compared to conventional single-channel derivations. This case study investigates the potential of HD-EMG classification longitudinally over a period of 17 months post-surgery in a glenohumeral amputee...

REVIEW
Dilip R Patel, Stephen Breisach
Shoulder pain in young athletes generally is a result of poor sports technique and overuse. A number intrinsic causes of shoulder pain have been identified. Pain may also be referred to shoulder area from cervical spine, neck and chest pathology. Overuse stress injury of the proximal humeral physis is important to recognize early in order to prevent later complications. Shoulder impingement syndrome is a general term used to describe multiple underlying lesions and relatively uncommon in young athletes. In adolescent athletes, glenohumeral instability is an important underlying pathomechanical basis for shoulder pain...

Stem mammaliaforms are Mesozoic forerunners to mammals, and they offer critical evidence for the anatomical evolution and ecological diversification during the earliest mammalian history. Two new eleutherodonts from the Late Jurassic period have skin membranes and skeletal features that are adapted for gliding. Characteristics of their digits provide evidence of roosting behaviour, as in dermopterans and bats, and their feet have a calcaneal calcar to support the uropagatium as in bats. The new volant taxa are phylogenetically nested with arboreal eleutherodonts...

BACKGROUND: The range of motion of the glenohumeral joint varies substantially among individuals and is dependent on humeral position. How variation in shape of the humerus and scapula affects shoulder axial range of motion at various positions has not been established. PURPOSE: To quantify variation in the shape of the glenohumeral joint and investigate whether the scapula and humerus geometries affect the axial rotational range of the glenohumeral joint. STUDY DESIGN: Descriptive laboratory study...

Anterior shoulder dislocations, subluxations, and recurrent instability of the shoulder joint are common problems usually affecting a young active population. However, it can be a problem for patients up to the late decades in life and can lead to major shoulder arthropathy if left untreated or improperly treated. This article discusses the natural history, pathologic morphologic changes of the shoulder joint associated with anterior instability along with normal anatomic variants. We will also discuss current treatment recommendations and possible causes of the patient with recurrent instability despite prior stabilization procedures...

Glenohumeral instability frequently occurs in young active individuals especially those engaged in athletic and military activities. With advanced imaging and arthroscopic evaluation, our understanding of the injury patterns associated with instability has significantly improved. The majority of instability results from a traumatic anterior event which presents with common findings in the history, examination, and imaging studies. As such, a comprehensive evaluation of the patient is important to correctly diagnose the instability patterns and thus provide appropriate treatment intervention...

Acute traumatic glenohumeral joint instability is common within the general population and endemic in young athletes and physically active populations. Individuals who experience acute traumatic glenohumeral joint instability events are at high risk of recurrent injury. In addition, glenohumeral joint instability results in substantial short-term and long-term consequences, including significant time loss from activity, degenerative joint changes, and reduced quality of life. This review provides an overview of the epidemiology of glenohumeral joint instability, reviews the modifiable and nonmodifiable risk factors for glenohumeral joint instability identified in the literature, and discusses the need for developing and implementing effective multilevel strategies for the primary, secondary, and tertiary prevention of glenohumeral joint instability and the long-term consequences associated with injury...

Glenohumeral instability secondary to glenohumeral bone loss presents a complex problem to the treating surgeon because of the complex biomechanics of the glenohumeral joint and its reliance on numerous dynamic and static stabilizers. The role of glenoid bone loss, specifically inferior-anterior glenoid bone loss, has been well characterized in the setting of recurrent unidirectional instability with greatly improved clinical results when following an algorithmic reconstructive approach to the location and percentage of overall bone loss...

The glenohumeral joint is one of the most frequently dislocated joints and occurs with increasing frequency in collision and contact athletes, especially those in sports that repeatedly place the glenohumeral joint in a position of vulnerability. Nonoperative management of shoulder instability especially in young contact athletes results in unacceptably high recurrence rates; thus, early surgical stabilization has become commonplace. Surgical stabilization typically yields acceptable outcomes. However, recurrent anterior instability may occur following a previous stabilization procedure at rates of 7% to 12%...

Glenohumeral instability is one of the more common conditions seen by sports medicine physicians, especially in young, active athletes. The associated anatomy of the glenohumeral joint (the shallow nature of the glenoid and the increased motion it allows) make the shoulder more prone to instability events as compared with other joints. Although traumatic dislocations or instability events associated with acute labral tears (ie, Bankart lesions) are well described in the literature, there exists other special shoulder conditions that are also associated with shoulder instability: superior labrum anterior/posterior (SLAP) tears, pan-labral tears, and multidirectional instability...

Shoulder dislocation and subsequent instability is a common problem in young athletes. Though it is not uncommon to attempt nonoperative rehabilitation in the early going, reinjury rates are high, particularly with contact sport athletes. As a result, many athletes will undergo a primary repair of one, or multiple, glenohumeral ligaments that make up the anterior shoulder capsule. This paper presents phases of rehabilitation from the preoperative stage up to returning to play. Criteria for phase progression are included, along with examples of common exercises and themes for each phase that allow the physical therapist to consider when working with patients who have had this type of shoulder surgery, allowing them to return to full function with low risk of reinjury...

Interscalene brachial plexus block is considered the most complete postoperative analgesia after total shoulder arthroplasty. Interscalene brachial plexus block-induced ipsilateral hemidiaphragmatic paralysis may not be tolerated in patients with preexisting pulmonary disease. Selective distal nerve blocks avoid the risk of phrenic nerve block; however, they may provide incomplete analgesia to the glenohumeral joint. We report a case of combined selective suprascapular and axillary nerve blockade in combination with local infiltration analgesia in a patient with severe lung disease undergoing total shoulder arthroplasty...
