Utilization of Interval Throwing Programs: Analysis of Athletic Trainer, Physical Therapist, and Physician Perspectives.

Context: A common component within rehabilitation recommendations for baseball pitchers is employment of an interval throwing program. However, there is a lack of a consistent set of advocated guidelines for program content and implementation for athletes at the professional and collegiate levels.

Design: Cross-sectional study.

Utilizing the Pronated Forearm Technique for Measuring Glenohumeral External Rotation in Baseball Players.

Background: Alterations in glenohumeral internal rotation (GIR), glenohumeral external rotation (GER), and total range of motion (TROM) have been linked with increased injury risk. GER capacity has been measured routinely with the forearm in neutral rotation (GERN), but a recent study reported GERN was greater than GER with the forearm in pronation (GERP) in Minor League pitchers. This work has not yet been replicated or extended to other groups.

Mass Participation and Tournament Event Management for the Team Physician: A Consensus Statement (2022 Update).

Mass participation events include endurance events (e.g., marathon, triathlon) and/or competitive tournaments (e.

Accuracy of measuring scapular position and motion with a novel motion capture system.

Background: Scapula kinematics is recognized to be a crucial variable in shoulder dysfunction. Nevertheless, quantitative scapula tracking and measurement are not part of the current clinical evaluation. The main concern is measurement accuracy.

Managing Scapular Dyskinesis.

Scapular dyskinesis, the impairment of optimal scapular position and motion, is common in association with shoulder injury. A comprehensive evaluation process can show the causative factors and lead to effective treatment protocols. The complexity of scapular motion and the integrated relationship between the scapula, humerus, trunk, and legs suggest a need to develop rehabilitation programs that involve all segments working as a unit rather than isolated components.

Acromioclavicular joint injuries revisited: Pathoanatomy, pathomechanics, and clinical presentation.

Multiple papers have described aspects of treatment of acromioclavicular (AC) joint injuries. Most have emphasized aspects of surgical treatment, and some papers have addressed non-operative treatment. Few papers have highlighted the specific pathoanatomy of an AC joint injury or have described methods of evaluating the 3-dimensional pathomechanics resulting from the pathoanatomical injury.

Glenoid Labral Injuries Are More Common Posteriorly Than Superiorly and Are Combined Across Multiple Areas of the Glenoid.

Purpose: To categorize arthroscopically observed labral injuries to include location on the glenoid and frequency of the injuries in each location.

Methods: Patients undergoing arthroscopic labral surgery between January 2018 and June 2020 were reviewed. Inclusion criteria for labral injury were consistently applied and included history, clinical examination and imaging findings, and failure of rehabilitation.

Nonoperative Management of Traumatic Acromioclavicular Joint Injury: A Clinical Commentary with Clinical Practice Considerations.

Unlabelled: Traumatic injuries of the acromioclavicular joint result in pain and potentially long-term alterations in scapulohumeral rhythm that occurs due to disruption of the clavicular strut function which is integral to scapular kinematics. Nonoperative treatment remains a valid option in most acromioclavicular joint injuries with the potential of minimizing pain and restoring scapulohumeral rhythm. However, few studies have provided nonoperative treatment details.

Soccer players show the highest seasonal groin pain prevalence and the longest time loss from sport among 500 athletes from major team sports.

Purpose: Groin pain is a widely recognized medical issue among athletes. Groin pain can affect both player and team performance and sometimes can be a career-ending injury. The aim of this study was to assess seasonal groin pain prevalence and the average seasonal time loss from sport for each injury in different team sport athletes.

Current Views of Scapular Dyskinesis and its Possible Clinical Relevance.

Scapular dyskinesis is a condition that is frequently observed clinically but not often understood. Too often it is viewed as a diagnosis which is not accurate because it is a physical impairment. This misclassification of dyskinesis has resulted in literature that simultaneously supports and refutes scapular dyskinesis as a relevant clinical entity as it relates to arm function.

Effect of Forearm Position on Glenohumeral External Rotation Measurements in Baseball Players.

Background: Alterations in glenohumeral internal rotation (GIR), glenohumeral external rotation (GER), and the total arc of motion (TAM) have been linked with increased injury risk in the shoulder and elbow. These motions have been routinely measured with the forearm in neutral rotation (GIRN, GERN, TAMN). GER capacity appears to be especially important.

Post-operative Rehabilitation for Scapular Muscle Reattachment: A Case Report.

Background And Purpose: Scapular muscle detachment is a rare orthopedic problem that has been described in the literature in patients following traumatic events involving traction, direct trauma, or a motor vehicle accident. The purpose of this case report is to describe the post-operative rehabilitation following scapular muscle reattachment surgery. Unique to this case report is the patient's perspective, an orthopedic physical therapist with 25 years of experience.

Evaluation and Management of Scapular Dyskinesis in Overhead Athletes.

Purpose Of Review: This review will outline scapular function in throwing, discuss scapular dyskinesis as an impairment of function that can be associated with throwing injuries and altered performance, and present an algorithm that encompasses guidelines for evaluation and can serve as a basis for treatment.

Recent Findings: Optimal scapular function is integral to optimal shoulder function. Multiple roles of the scapula in arm function and throwing have been identified while scapular dysfunction continues to be associated with various shoulder pathologies.

Comparable clinical and functional outcomes after anterior cruciate ligament reconstruction over and under 40 years of age.

Purpose: The aim of the present meta-analysis was to update the literature on the outcomes and complications of ACL reconstruction in patients aged 40 years and older. It has been hypothesized that patients older than 40 years of age may have comparable clinical outcomes to those of younger patients.

Methods: A systematic review of articles from 1996 to 2018 was completed using Pubmed, Medline, Cochrane Reviews, and Google Scholar databases using the keyword terms "anterior cruciate ligament reconstruction" and "middle-aged OR elderly OR over 40 OR age factors.

Neuromuscular adaptations in shoulder function and dysfunction.

Neuromuscular activity, organized in coordinated patterns, forms the basis of task-specific function in sports and exercise. The content and extent of these patterns may be variable, but include elements of activation/inhibition, co-activation, concentric/eccentric activation, proximal-to-distal activation, plyometric activation, and preactivation stiffness. They may be based on inherent neuromuscular architecture, but are commonly affected by positive or negative adaptations to imposed functional demands.

Pain catastrophizing behaviors and their relation to poor patient-reported outcomes after scapular muscle reattachment.

Hypothesis: We hypothesized that the patient-reported status following treatment of traumatic scapular muscle detachment would improve from the preoperative status and that higher pain catastrophizing scores would be more common in patients with poor postsurgical outcomes.

Methods: We studied 50 patients who met the diagnostic criteria for scapular muscle detachment and in whom rehabilitation failed. American Shoulder and Elbow Surgeons (ASES) scores were collected preoperatively and postoperatively.

Clinical and radiographic outcomes after total shoulder arthroplasty with an anatomic press-fit short stem.

Background: There is limited information assessing outcomes after total shoulder arthroplasty (TSA) with a press-fit short stem. The purpose of this study was to evaluate early clinical and radiographic outcomes and complications after TSA with an anatomic press-fit short stem.

Methods: We identified 118 TSAs completed with press-fit short stem and minimum 2-year follow-up; 85 of these patients had a grit-blasted (GB) short stem placed, whereas 33 patients had short stems with proximal porous coating (PPC).

RELIABILITY AND VALIDITY OF A BIOMECHANICALLY BASED ANALYSIS METHOD FOR THE TENNIS SERVE.
