ERGONOMICS 2023:1-29. [PMID: 38039103 DOI: 10.1080/00140139.2023.2290983] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Accepted: 11/29/2023] [Indexed: 12/03/2023]
Abstract
Subacromial pain syndrome (SAPS) is the most common upper-extremity musculoskeletal problem among workers. In this study, a machine learning model was built to predict and classify the presence or absence of SAPS in assembly workers with shoulder joint range of motion (ROM) and muscle strength data using support vector machine (SVM). Permutation importance was used to determine important variables for predicting workers with or without SAPS. The accuracy of the support vector classifier (SVC) polynomial model for classifying workers with SAPS was 82.4%. The important variables in model construction were internal rotation and abduction of shoulder ROM and internal rotation of shoulder muscle strength. It is possible to accurately perform SAPS classification of workers with relatively easy-to-obtain shoulder ROM and muscle strength data using this model. In addition, preventing SAPS in workers is possible by adjusting the factors affecting model building using exercise or rehabilitation programs.

Abstract
The COVID-19 pandemic drastically changed many aspects of the traditional functioning of health systems all around the world. In Italy, as reported by the CIO, compared to the previous year, there was a significant reduction in 2020 in overall outpatient activities by up to 75%. These data support the need for telemedicine, which represents a current challenge and can no longer be postponed in the future. This study aims to elaborate on a possible model for remote shoulder examination based on traditional tests to improve the quality of telemedicine in orthopedic and rehabilitation. Between May 2020 and November 2020, ten orthopedic surgeons individually examined six patients with a known shoulder disorder, both in hospital and via webcam according to the previously shared protocol (B-STEP). According to the 10 observers, completing 100% of the ASES score and at least 87.5% of the Constant score is possible. Shoulder ROM and many specific tests are also reproducible via webcam, but with less sensitivity, according to the subjective opinion of observers. The B-STEP is a useful protocol for the standardization of the objective examination of the shoulder via webcam. Further studies are necessary to determine if the B-STEP protocol is useful for diagnosing pathology in unknown patients and evaluating its sensitivity and specificity for each pathology.

Abstract
Athletes participating in overhead sports are at particularly high risk of shoulder impingement syndrome. Subcoracoid impingement is defined as impingement of the anterior soft tissues of the shoulder between the coracoid process and the lesser tuberosity. Subacromial impingement syndrome (SIS) occurs due to extrinsic compression of the rotator cuff between the humeral head and coracoacromial structures or intrinsic degeneration of the supraspinatus tendon and subsequent superior migration of the humerus. Internal impingement is a major cause of shoulder pain in overhead athletes, and it occurs due to repetitive impingement of the articular surface of the rotator cuff with the glenoid during maximum abduction and external rotation of the arm. When examining athletes with suspected impingement of the shoulder, it is important to discuss the sport-specific motion that regenerates the symptoms and perform a combination of physical examination tests to improve the diagnostic accuracy. Radiographic evaluation is recommended, and the extent of soft tissue abnormalities can be assessed on ultrasound or magnetic resonance imaging of the shoulder. Management of shoulder impingement syndrome can be conservative or operative, based on the severity and chronicity of symptoms and the associated structural abnormalities. This review provides an update on the management of SIS, subcoracoid impingement, and internal impingement in the athletic population.

Abstract
PURPOSE OF REVIEW This review presents epidemiology, etiology, management, and surgical outcomes of rotator cuff injuries in tennis players. RECENT FINDINGS Rotator cuff injuries in tennis players are usually progressive overuse injuries ranging from partial-thickness articular- or bursal-sided tears to full-thickness tears. Most injuries are partial-thickness articular-sided tears, while full-thickness tears tend to occur in older-aged players. The serve is the most energy-demanding motion in the sport, and it accounts for 45 to 60% of all strokes performed in a tennis match, putting the shoulder at increased risk of overuse injury and rotator cuff tears. Studies have shown deficits in shoulder range of motion and scapular dyskinesia to occur even acutely after a tennis match. First-line treatment for rotator cuff injuries in any overhead athlete consists of conservative non-operative management with appropriate rest, anti-inflammatory drugs, followed by a specific rehabilitation program. Operative treatment is usually reserved for older-aged players and to those who fail to return to play after conservative measures. Surgical options include rotator cuff debridement with or without tendon repair, biceps tenodesis, and labral procedures. Unlike rotator cuff repairs in the general population, repairs in the elite tennis athlete have less than ideal rates of return to sport to the same level of performance. Rotator cuff injuries are a common cause of pain and dysfunction in tennis players and other overhead athletes. The etiology of rotator cuff tears in tennis players is multifactorial and usually results from microtrauma and internal impingement in the younger athlete leading to partial tearing and degenerative full-thickness tears in older players. Surgical treatment is pursued in athletes who are still symptomatic despite an extensive course of non-operative treatment as outcomes with regard to returning to sport to the same pre-injury level are modest at best. Debridement alone is usually preferred over rotator cuff repairs for partial tears in younger players due to potential over-constraining of the shoulder joint and decreased rates of return to sport after rotator cuff repairs.

Abstract
Background: There is limited information about the agreement and reliability of clinical shoulder tests. Objectives: To assess the interrater agreement and reliability of clinical shoulder tests in patients with shoulder pain treated in primary care. Methods: Patients with a primary report of shoulder pain underwent a set of 21 clinical shoulder tests twice on the same day, by pairs of independent physical therapists. The outcome parameters were observed and specific interrater agreement for positive and negative scores, and interrater reliability (Cohen's kappa (κ)). Positive and negative interrater agreement values of ≥0.75 were regarded as sufficient for clinical use. For Cohen's κ, the following classification was used: <0.20 poor, 0.21-0.40 fair, 0.41-0.60 moderate, 0.61-0.80 good, 0.81-1.00 very good reliability. Participating clinics were randomized in two groups; with or without a brief practical session on how to conduct the tests. Results: A total of 113 patients were assessed in 12 physical therapy practices by 36 physical therapists. Positive and negative interrater agreement values were both sufficient for 1 test (the Full Can Test), neither sufficient for 5 tests, and only sufficient for either positive or negative agreement for 15 tests. Interrater reliability was fair for 11 tests, moderate for 9 tests, and good for 1 test (the Full Can Test). An additional brief practical session did not result in better agreement or reliability. Conclusion: Clinicians should be aware that interrater agreement and reliability for most shoulder tests is questionable and their value in clinical practice limited.

Abstract
PURPOSE OF REVIEW To review the etiology, classification, presentation, evaluation, treatment strategy, and outcomes in overhead athletes with partial thickness rotator cuff tears. RECENT FINDINGS Despite advances in surgical repair techniques, return to play following surgical repair of partial rotator cuff tears remains modest at best. Overhead athletes may be particularly prone to rotator cuff pathology due to the supraphysiological strains within the tendon during the throwing motion, as well as mechanical stress with contact between the undersurface of the rotator cuff and the glenoid. The true prevalence of partial tears may be underestimated given the high incidence of asymptomatic tears. Both dynamic ultrasound and enhanced contrast MRI have improved our understanding of this pathology. For most overhead athletes, nonoperative management is the most common course. Despite advances in imaging, diagnosis, and surgical techniques, our ability to return these patients to their elite level is modest at best when nonoperative management fails and surgical treatment is performed. If a surgical route is needed, debridement alone is the most frequent procedure given concerns of over constraint and poor return to play with surgical repair of the partial thickness rotator cuff tear.

BMC Musculoskelet Disord 2017; 18:41. [PMID: 28122541 PMCID: PMC5267375 DOI: 10.1186/s12891-017-1400-0] [Citation(s) in RCA: 61] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2016] [Accepted: 01/11/2017] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Physical examination tests of the shoulder (PETS) are clinical examination maneuvers designed to aid the assessment of shoulder complaints. Despite more than 180 PETS described in the literature, evidence of their validity and usefulness in diagnosing the shoulder is questioned. METHODS This meta-analysis aims to use diagnostic odds ratio (DOR) to evaluate how much PETS shift overall probability and to rank the test performance of single PETS in order to aid the clinician's choice of which tests to use. This study adheres to the principles outlined in the Cochrane guidelines and the PRISMA statement. A fixed effect model was used to assess the overall diagnostic validity of PETS by pooling DOR for different PETS with similar biomechanical rationale when possible. Single PETS were assessed and ranked by DOR. Clinical performance was assessed by sensitivity, specificity, accuracy and likelihood ratio. RESULTS Six thousand nine-hundred abstracts and 202 full-text articles were assessed for eligibility; 20 articles were eligible and data from 11 articles could be included in the meta-analysis. All PETS for SLAP (superior labral anterior posterior) lesions pooled gave a DOR of 1.38 [1.13, 1.69]. The Supraspinatus test for any full thickness rotator cuff tear obtained the highest DOR of 9.24 (sensitivity was 0.74, specificity 0.77). Compression-Rotation test obtained the highest DOR (6.36) among single PETS for SLAP lesions (sensitivity 0.43, specificity 0.89) and Hawkins test obtained the highest DOR (2.86) for impingement syndrome (sensitivity 0.58, specificity 0.67). No single PETS showed superior clinical test performance. CONCLUSIONS The clinical performance of single PETS is limited. However, when the different PETS for SLAP lesions were pooled, we found a statistical significant change in post-test probability indicating an overall statistical validity. We suggest that clinicians choose their PETS among those with the highest pooled DOR and to assess validity to their own specific clinical settings, review the inclusion criteria of the included primary studies. We further propose that future studies on the validity of PETS use randomized research designs rather than the accuracy design relying less on well-established gold standard reference tests and efficient treatment options.

Abstract
A systematic clinical examination of the shoulder joint, including a structured medical history, is essential for the diagnosis of shoulder pathologies. Complex clinical situations that are accompanied by pain, restriction of movement, loss of strength, or instability have to be considered in accordance with the functional interaction between the cervical spine, the shoulder girdle, and the glenohumeral joint. Only accurate diagnosis allows us to apply successful therapeutic interventions. In order to achieve this, the physician needs to use standardized clinical tests and signs combined with a profound knowledge of the anatomy and the possible underlying pathologies. To ensure a structured approach as well as a complete documentation of results, a shoulder assessment form should be used. The information obtained from the history, examination, and collected data form the basis for further diagnostic imaging.

Abstract
PURPOSE To evaluate a chemical shift-based fat quantification technique in the rotator cuff muscles in comparison with the semiquantitative Goutallier fat infiltration classification (GC) and to assess their relationship with clinical parameters. MATERIALS AND METHODS The shoulders of 57 patients were imaged using a 3T MR scanner. The rotator cuff muscles were assessed for fat infiltration using GC by two radiologists and an orthopedic surgeon. Sequences included oblique-sagittal T1-, T2-, and proton density-weighted fast spin echo, and six-echo gradient echo. The iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL) was used to measure fat fraction. Pain and range of motion of the shoulder were recorded. RESULTS Fat fraction values were significantly correlated with GC grades (P < 0.0001, κ >0.9) showing consistent increase with GC grades (grade = 0, 0%-5.59%; grade = 1, 1.1%-9.70%; grade = 2, 6.44%-14.86%; grade = 3, 15.25%-17.77%; grade = 4, 19.85%-29.63%). A significant correlation between fat infiltration of the subscapularis muscle quantified with IDEAL versus 1) deficit in internal rotation (Spearman Rank Correlation Coefficient [SRC] = 0.39, 95% confidence interval [CI] 0.13-0.60, P < 0.01) and 2) pain (SRC coefficient = 0.313, 95% CI 0.049-0.536, P = 0.02) was found but was not seen between the clinical parameters and GC grades. Additionally, only quantitative fat infiltration measures of the supraspinatus muscle were significantly correlated with a deficit in abduction (SRC coefficient = 0.45, 95% CI 0.20-0.60, P < 0.01). CONCLUSION An accurate and highly reproducible fat quantification in the rotator cuff muscles using water-fat magnetic resonance imaging (MRI) techniques is possible and significantly correlates with shoulder pain and range of motion.

Abstract
BACKGROUND Impingement is a common cause of shoulder pain. Impingement mechanisms may occur subacromially (under the coraco-acromial arch) or internally (within the shoulder joint), and a number of secondary pathologies may be associated. These include subacromial-subdeltoid bursitis (inflammation of the subacromial portion of the bursa, the subdeltoid portion, or both), tendinopathy or tears affecting the rotator cuff or the long head of biceps tendon, and glenoid labral damage. Accurate diagnosis based on physical tests would facilitate early optimisation of the clinical management approach. Most people with shoulder pain are diagnosed and managed in the primary care setting. OBJECTIVES To evaluate the diagnostic accuracy of physical tests for shoulder impingements (subacromial or internal) or local lesions of bursa, rotator cuff or labrum that may accompany impingement, in people whose symptoms and/or history suggest any of these disorders. SEARCH METHODS We searched electronic databases for primary studies in two stages. In the first stage, we searched MEDLINE, EMBASE, CINAHL, AMED and DARE (all from inception to November 2005). In the second stage, we searched MEDLINE, EMBASE and AMED (2005 to 15 February 2010). Searches were delimited to articles written in English. SELECTION CRITERIA We considered for inclusion diagnostic test accuracy studies that directly compared the accuracy of one or more physical index tests for shoulder impingement against a reference test in any clinical setting. We considered diagnostic test accuracy studies with cross-sectional or cohort designs (retrospective or prospective), case-control studies and randomised controlled trials. DATA COLLECTION AND ANALYSIS Two pairs of review authors independently performed study selection, assessed the study quality using QUADAS, and extracted data onto a purpose-designed form, noting patient characteristics (including care setting), study design, index tests and reference standard, and the diagnostic 2 x 2 table. We presented information on sensitivities and specificities with 95% confidence intervals (95% CI) for the index tests. Meta-analysis was not performed. MAIN RESULTS We included 33 studies involving 4002 shoulders in 3852 patients. Although 28 studies were prospective, study quality was still generally poor. Mainly reflecting the use of surgery as a reference test in most studies, all but two studies were judged as not meeting the criteria for having a representative spectrum of patients. However, even these two studies only partly recruited from primary care.The target conditions assessed in the 33 studies were grouped under five main categories: subacromial or internal impingement, rotator cuff tendinopathy or tears, long head of biceps tendinopathy or tears, glenoid labral lesions and multiple undifferentiated target conditions. The majority of studies used arthroscopic surgery as the reference standard. Eight studies utilised reference standards which were potentially applicable to primary care (local anaesthesia, one study; ultrasound, three studies) or the hospital outpatient setting (magnetic resonance imaging, four studies). One study used a variety of reference standards, some applicable to primary care or the hospital outpatient setting. In two of these studies the reference standard used was acceptable for identifying the target condition, but in six it was only partially so. The studies evaluated numerous standard, modified, or combination index tests and 14 novel index tests. There were 170 target condition/index test combinations, but only six instances of any index test being performed and interpreted similarly in two studies. Only two studies of a modified empty can test for full thickness tear of the rotator cuff, and two studies of a modified anterior slide test for type II superior labrum anterior to posterior (SLAP) lesions, were clinically homogenous. Due to the limited number of studies, meta-analyses were considered inappropriate. Sensitivity and specificity estimates from each study are presented on forest plots for the 170 target condition/index test combinations grouped according to target condition. AUTHORS' CONCLUSIONS There is insufficient evidence upon which to base selection of physical tests for shoulder impingements, and local lesions of bursa, tendon or labrum that may accompany impingement, in primary care. The large body of literature revealed extreme diversity in the performance and interpretation of tests, which hinders synthesis of the evidence and/or clinical applicability.

Abstract
BACKGROUND The active compression test has been described to detect superior labrum anterior and posterior (SLAP) lesions. Some have speculated that contact between the lesser tuberosity and the superior glenoid in the testing position causes a positive test. This study evaluated the location of peak glenohumeral contact pressures during a simulated active compression test in a cadaveric model with and without SLAP lesions. MATERIALS AND METHODS Six specimens were tested. A pressure sensor was used to record glenohumeral contact, and a motion analysis system was used to measure humeral head translation. Contact pressures and translations were measured during serial deltoid and biceps loads. These were repeated for small and large SLAP lesions. RESULTS There was a notable shift in the location of peak contact pressure from the anterior-inferior glenoid to the anterior-superior glenoid with increasing deltoid load. Deltoid loading translated the humeral head posteriorly relative to the glenoid. Conversely, biceps loads countered the pull of the deltoid only when the biceps load was greater than the deltoid load. The SLAP tears did not significantly alter the degree of humeral head translation or location of the contact pressures. CONCLUSIONS In the active compression test, the posterior capsule is taut and the anterior capsule is lax, which permits the deltoid to translate the humeral head posteriorly. This shift in the peak contact pressure to the superior glenoid may elicit a positive active compression test. LEVEL OF EVIDENCE Basic Science Study, Biomechanics, Cadaver Model.

Abstract
OBJECTIVE To examine the accuracy of clinical tests for diagnosing subacromial impingement syndrome (SIS). DATA SOURCES A systematic literature search was conducted in January 2011 to identify all studies that examined the diagnostic accuracy of clinical tests for SIS. The following search engines were used: Cochrane Library, EMBASE, Science Direct, and PubMed. STUDY SELECTION Two reviewers screened all articles. We included prospective or retrospective cohort studies that examined individuals with a painful shoulder, reported any clinical test for SIS, and used arthroscopy or open surgery as the reference standard. The search strategy yielded 1338 articles of which 1307 publications were excluded based on title/abstract. Sixteen of the remaining 31 articles were included. The PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines were followed to conduct this review. DATA EXTRACTION The number of true positives, false positives, true negatives, and false negatives for each clinical test were extracted from relevant studies, and a 2×2 table was constructed. Studies were combined using a bivariate random-effects model. Heterogeneity was assessed using the variance of logit-transformed sensitivity and specificity. DATA SYNTHESIS Ten studies with 1684 patients are included in the meta-analysis. The Hawkins-Kennedy test, Neer's sign, and empty can test are shown to be more useful for ruling out rather than ruling in SIS, with greater pooled sensitivity estimates (range, .69-.78) than specificity (range, .57-.62). A negative Neer's sign reduces the probability of SIS from 45% to 14%. The drop arm test and lift-off test have higher pooled specificities (range, .92-.97) than sensitivities (range, .21-.42), indicating that they are more useful for ruling in SIS if the test is positive. CONCLUSIONS This systematic review quantifies the diagnostic accuracy of 5 clinical tests for SIS, in particular the lift-off test. Accurate diagnosis of SIS in clinical practice may serve to improve appropriate treatment and management of individuals with shoulder complaints.

Abstract
BACKGROUND Humeral avulsion of the inferior glenohumeral ligament is a rare injury resulting from hyperabduction and external rotation, and it is most commonly seen with sports-related injuries, including those from volleyball. The anterior band of the inferior glenohumeral ligament is most commonly injured (93%), whereas the posterior band is infrequently injured. The axillary pouch humeral avulsion of the inferior glenohumeral ligament as a result of repetitive microtrauma has not been yet described in the English literature. HYPOTHESIS Humeral avulsions of the inferior glenohumeral ligaments are identifiable in volleyball players without acute injuries, and they have a unique pathologic pattern in these athletes. STUDY DESIGN Case series; Level of evidence, 4. METHODS Four female college volleyball players with pain in their dominant shoulder and with inferior capsular laxity and/or instability—without a known history of trauma or dislocation of the same shoulder—were referred by an experienced sports medicine orthopaedic surgeon for the magnetic resonance arthrogram procedure of the same shoulder. The imaging findings were retrospectively correlated with the initial interpretation and arthroscopic findings. RESULTS All 4 patients had an axillary pouch humeral avulsion of the inferior glenohumeral ligament. Three had articular surface partial-thickness rotator cuff tear, and 3 had a labral tear. All were outside hitters or middle blockers who consequently performed multiple hitting maneuvers in practice and games. CONCLUSION Repetitive microtrauma from overhead hitting in volleyball generates forces on the inferior capsule of the shoulder joint that may cause inferior capsular laxity and subsequent failure of the humeral side of the axillary pouch portion of the inferior glenohumeral ligament.

Co-occurrence of outlet impingement syndrome of the shoulder and restricted range of motion in the thoracic spine--a prospective study with ultrasound-based motion analysis. BMC Musculoskelet Disord 2010; 11:135. [PMID: 20587014 PMCID: PMC2903509 DOI: 10.1186/1471-2474-11-135] [Citation(s) in RCA: 36] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2009] [Accepted: 06/29/2010] [Indexed: 11/10/2022] Open
Abstract
Background Shoulder complaints, and especially the outlet-impingement syndrome, are a common condition. Among other things, poor posture has been discussed as a cause. A correlation between impingement syndrome and restricted mobility of the thoracic spine (T) has been described earlier, but there has been no motion analysis of the thoracic spine to show these correlations. In the present prospective study, we intended to find out whether there is a significant difference in the thoracic sagittal range of motion (ROM) between patients with a shoulder outlet impingement syndrome and a group of patients who had no shoulder pathology. Secondly, we wanted to clarify whether Ott's sign correlates with ultrasound topometric measurements. Methods Two sex- and age-matched groups (2 × n = 39) underwent a clinical and an ultrasound topometric examination. The postures examined were sitting up straight, sitting in maximal flexion and sitting in maximal extension. The disabilities of the arm, shoulder and hand (DASH) score (obtained by means of a self-assessment questionnaire) and the Constant score were calculated. Lengthening and shortening of the dorsal projections of the spine in functional positions was measured by tape with Ott's sign. Results On examination of the thoracic kyphosis in the erect seated posture there were no significant differences between the two groups (p = 0.66). With ultrasound topometric measurement it was possible to show a significantly restricted segmental mobility of the thoracic spine in the study group compared with the control group (p = 0.01). An in-depth look at the mobility of the subsegments T1-4, T5-8 and T9-12 revealed that differences between the groups in the mobility in the lower two sections of the thoracic spine were significant (T5-8: p = 0.03; T9-12: p = 0.02). The study group had an average Constant score of 35.1 points and the control group, 85.5 (p < 0.001). On the DASH score the patient group reached 34.2 points and the control group, 1.4 (p < 0.001). The results of Ott's sign differed significantly between the two collectives (p = 0.0018), but showed a weak correlation with the ultrasound topometric measurements (study group flexion/extension: r = 0.36/0.43, control group flexion/extension: r = 0.29/0.26). Conclusion The mobility of the thoracic spine should receive more attention in the diagnosis and therapy of patients with shoulder outlet impingement syndrome.

Abstract
Objective: To determine the diagnostic accuracy of commonly used physical tests for subacromial impingement syndrome, using ultrasound as the reference standard. Design: A cross-sectional study of 59 participants with chronic shoulder pain of more than four months duration with a referral for diagnostic ultrasound scanning were invited to participate in the study. Main measures: Thirty-four participants met the inclusion criteria and had an ultrasound scan followed immediately by application of the following tests: Neer’s sign, Hawkins and Kennedy test, painful arc of abduction, empty and full can tests, resisted isometric shoulder abduction and resisted isometric shoulder external rotation. Using the two-way contingency table method sensitivity, specificity, likelihood ratios and overall accuracy were calculated for each physical test. Results: Diagnostic values for each test varied considerably. The Hawkins and Kennedy test was the most accurate test for diagnosing any degree of subacromial impingement syndrome (71.0%). The most accurate tests for diagnosing subcategories of impingement were pain on resisted external rotation and weakness during the full can test (63.6%) for presence of subdeltoid fluid, pain on resisted external rotation (58.8%) for partial thickness tears and the painful arc test (62.1%) for full thickness tears. Conclusions: As the predictive values of these tests are shown to be variable in this study it indicates that the clinical tests identified have limited use in informing diagnosis. Emphasis on the management of dysfunction may be more appropriate rather than reliance on clinical tests with inconclusive sensitivity and specificity if ultrasound scanning is not available.

Fluoroscopic assessment of rotator cuff fatigue on glenohumeral arthrokinematics in shoulder impingement syndrome. J Shoulder Elbow Surg 2009; 18:968-75.

Abstract
BACKGROUND Although prior researchers have assessed glenohumeral arthrokinematics using isometrically held arm postures with standard radiographs, dynamic assessment of glenohumeral arthrokinematics has been limited. This study utilized video fluoroscopy to analyze superior inferior glenohumeral migration during dynamic arm elevation in individuals with outlet impingement syndrome, before and after fatigue of the rotator cuff. HYPOTHESIS Prior to the study, it was hypothesized that during the pre-fatigue state, glenohumeral migration would be in the superior direction, and that post-fatigue there would be a significant increase in superior migration. MATERIALS AND METHODS Digital fluoroscopic videos (30 Hz) were used to analyze 20 male volunteers (27.7 +/- 7.3 years) with right shoulder outlet impingement syndrome during concentric elevation of the arm in the plane of the scapula, both before and after fatigue of the rotator cuff. RESULTS During concentric arm elevation, there was superior glenohumeral migration (1.6 mm) between 45 degrees and 90 degrees of arm elevation, regardless of fatigue-state (P = .02). After rotator cuff fatigue, the humeral head was positioned more superiorly on the glenoid fossa (P = .03). The position of the humeral head was 0.4 mm more superior than that reported in a previous study on healthy individuals. CONCLUSION These results support prior findings that suggest superior glenohumeral migration during arm elevation is influenced both by shoulder pathology and the state of fatigue of the rotator cuff musculature. Future research should examine the effects of physical therapy and surgical interventions on glenohumeral arthrokinematics to better determine the most effective treatment methods for outlet impingement.

Abstract
Partial-thickness cuff tears (PTCTs) are increasingly recognized as a source of pain and athletic impairment, especially in overhead athletes. 1,2 Improvements in diagnostic imaging have enhanced the ability to detect and quantify partial cuff disease, and arthroscopic advances have led to novel techniques by which partial cuff tears can be repaired. 2-6 Despite increasing recognition and improved understanding of this condition, the natural history, clinical evaluation, and management of partial tears remain elusive. This is because of the disparity between the extent of partial cuff tearing and the wide variability in clinical impairment and the frequent overlay of concomitant labral and subacromial pathology. When should operating on an athlete with a partial cuff tear be considered? What percentage of cuff tear justifies repair rather than debridement? Does this threshold vary according to the athlete or sport? And if the partial tear is repaired, what can be expected in terms of return to activity, particularly in a high-level thrower? The purpose of this manuscript is to provide an overview of partial cuff tears and their evaluation and management.

Abstract
QUESTION Do clinical tests accurately diagnose rotator cuff pathology? DESIGN A systematic review of investigations into the diagnostic accuracy of clinical tests for rotator cuff pathology. PARTICIPANTS People with shoulder pain who underwent clinical testing in order to diagnose rotator cuff pathology. OUTCOME MEASURES The diagnostic accuracy of clinical tests was determined using likelihood ratios. RESULTS Thirteen studies met the inclusion criteria. The 13 studies evaluated 14 clinical tests in 89 separate evaluations of diagnostic accuracy. Only one evaluation, palpation for supraspinatus ruptures, resulted in significant positive and negative likelihood ratios. Eight of the 89 evaluations resulted in either significant positive or negative likelihood ratios. However, none of these eight positive or negative likelihood ratios were found in other studies. Of the 89 evaluations of clinical tests 71 (80%) did not result in either significant positive or negative likelihood ratio evaluations across different studies. CONCLUSION Overall, most tests for rotator cuff pathology were inaccurate and cannot be recommended for clinical use. At best, suspicion of a rotator cuff tear may be heightened by a positive palpation, combined Hawkins/painful arc/infraspinatus test, Napoleon test, lift-off test, belly-press test, or drop-arm test, and it may be reduced by a negative palpation, empty can test or Hawkins-Kennedy test.

Abstract
OBJECTIVE To investigate whether the lag signs were valid tools in diagnosing full-thickness tears of the rotator cuff. DESIGN A same-subject, correlation, double-blinded design was used. The results of the external rotation lag sign, drop sign, and internal rotation lag sign were compared with the criterion standard of diagnostic ultrasound to establish their accuracy. SETTING A regional orthopedic hospital. PARTICIPANTS Consecutive subjects (N=37), 21 women and 16 men, with shoulder pain referred to a consultant orthopedic surgeon specializing in shoulder conditions were recruited for this investigation. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Sensitivity, specificity, and positive and negative likelihood ratios of the lag signs when using ultrasound as the reference test. RESULTS The specificities of the drop sign and internal rotation lag sign were 77% and 84%, respectively, which, together with low positive likelihood ratios 3.2 (95% confidence interval [CI], 1.5-6.7) and 6.2 (95% CI, 1.9-12.0), indicate that a positive result was poor at recognizing the presence of full-thickness tears. The drop sign had a sensitivity of 73% with a negative likelihood ratio of .34 (95% CI, 0.2-0.8), suggesting that a negative test was fair at ruling out the presence of full-thickness tears. The sensitivity of the internal rotation lag sign (100%) supported by the negative likelihood ratio of 0 (95% CI, 0.0-2.5) suggests that a negative test will effectively rule out the presence of full-thickness tears of the subscapularis. A positive external rotation lag sign is the clinical test most likely to indicate that full-thickness tears of the supraspinatus and infraspinatus are present (specificity, 94%). However, the external rotation lag sign did demonstrate a low sensitivity score of 46% and negative likelihood ratio of .57 (95% CI, 0.4-0.9), which means that a negative test will not rule out the presence of full-thickness tears. CONCLUSIONS The findings of this investigation suggest that a clinical diagnosis of a full-thickness tear of the rotator cuff cannot be conclusively reached using one or more of the lag signs.

Abstract
STUDY DESIGN Systematic literature review. OBJECTIVES To conduct a systematic review of case series and clinical trials that investigate the diagnostic accuracy of clinical tests for superior labral anterior posterior (SLAP) lesions. BACKGROUND Primary contact practitioners are often presented with shoulder problems and use a battery of clinical tests to reach a diagnosis. Early detection of SLAP pathology may lead to more optimal interventions and better outcomes for patients. METHODS AND MEASURES The OVID search interface was utilized with MEDLINE, AHMED, CINAHL, and SPORTDiscus databases searched from 1996-2006. Studies were retrieved that included patients with shoulder pain who underwent at least 1 clinical shoulder test for SLAP lesions. For an article to be included in this review, the results of the clinical tests needed to be compared with findings on arthroscopy. Quality of the manuscripts included in this review were rated using the QUADAS appraisal tool, so comparisons could be made across studies. RESULTS Seventeen published manuscripts fit the inclusion/exclusion criteria and were used for this review. Eight studies were found to be of high quality. Within these 8 studies, 1 group of authors reported high diagnostic accuracy values for the crank test: sensitivity, 91% (95% confidence interval [CI], 76%-97%); specificity, 93% (95% CI, 79%-88%); positive likelihood ratio, 13.6 (95% CI, 3.6-52.1); and negative likelihood ratio, 0.1 (95% CI, 0.0-0.3). One study on the resisted supination external rotation test also scored high on the QUADAS and reported diagnostic accuracy values of 83% (95% CI, 66-92), 82% (95% CI, 52-95), 4.6 (95% CI, 1.3-16.1), and 0.20 (95% CI, 0.1-0.5), respectively. Of significance is the fact that the majority of papers reporting highly accurate clinical diagnostic tests were of low quality with the results not supported by other authors. CONCLUSION It appears that no single test is sensitive or specific enough to determine the presence of a SLAP lesion accurately. Further research is required to determine whether subgrouping of patients by mechanism of injury or the type of SLAP lesion may improve diagnostic accuracy. Determining the diagnostic accuracy of a combination of 2 or more tests is also needed.

Abstract
STUDY DESIGN Case report. BACKGROUND Patients who sustain first-episode anterior glenohumeral dislocations are at risk to develop chronic glenohumeral instability. Current treatment options after an initial anterior glenohumeral dislocation include immediate surgery, delayed surgery, or conservative interventions such as immobilization and strengthening exercises. Duration of immobilization is variable among formal studies. Recent research suggests that typical immobilization positions may not allow adequate healing and in fact may promote glenohumeral joint instability. CASE DESCRIPTION The patient was a 19-year-old male who sustained a first-episode anterior glenohumeral dislocation during athletic activity. Physical therapy management included a longer-than-typical period of immobilization and protected activity to allow for more complete healing. The shoulder abduction and neutral rotation immobilization position used with this patient may increase healing of structures that influence stability of the shoulder OUTCOMES At 13 weeks after the dislocation, the patient had full active and passive range of motion, near normal strength, and no complaints of pain or instability. At a 20-month follow-up the patient had resumed full activities of daily living including recreational sports without symptoms of instability. DISCUSSION Conservative intervention options for first-episode anterior shoulder dislocations need further study. Immobilization and protected activity periods should be adequate to allow for complete healing. The optimal positions for immobilization should be determined and implemented.

Abstract
Rotator cuff tears are a common cause of shoulder pain. Clinical and radiographic findings can suggest the presence of a rotator cuff tear. The most sensitive clinical findings are impingement and the "arc of pain" sign. Radiographic findings are usually normal in the acute setting, although the "active abduction" view may show decreased acromiohumeral distance. In more chronic cases, an outlet view may show decreased opacity and decreased size of the supraspinatus muscle due to atrophy. In late cases, the humeral head may become subluxated superiorly, and secondary degenerative arthritis of the glenohumeral joint may ensue. Ultrasonography (US), with over 90% sensitivity and specificity, can help confirm the diagnosis in clinically or radiographically equivocal cases. US can also reveal the presence of other abnormalities that may mimic rotator cuff tear at clinical examination, including tendinosis, calcific tendinitis, subacromial subdeltoid bursitis, greater tuberosity fracture, and adhesive capsulitis.

Abstract
Successful treatment of any pathologic condition of the shoulder requires an accurate diagnosis. Physical examination represents an integral part in the assessment of shoulder disorders. Pain, loss of strength, decreased range of motion and instability are the most common symptoms that can be caused by a great variety of different shoulder pathologies. Therefore, a sophisticated clinical approach is essential. A standardized evaluation including different diagnostic tests and clinical signs improves diagnostic accuracy by specifically examining one component of the shoulder complex. In most cases a careful physical examination will establish or suggest a diagnosis and special investigative techniques such as imaging procedures can be applied more selectively for confirmation or further evaluation of the pathological entity.

Abstract
Careful examination of the shoulder is an essential component in forming a diagnosis of problems in this area. A number of tests have been described that are claimed to improve diagnostic accuracy by specifically examining one component of the shoulder complex. Many of these tests are eponymous, and there is confusion about not only how to perform them but also what conclusion to draw from the results. This article attempts to clarify the tests used to examine the rotator cuff by presenting them as described by the original authors with the additional aim of providing a source for those wishing to refresh their knowledge without the need to refer to the original source material.
