Background:
Electromagnetic tracking systems have enabled some investigators and clinicians to measure tri‐planar scapular motion; yet, they are not practical and affordable options for all clinicians. Currently, the ability to affordably quantify scapular motion is limited to monitoring only the motion of scapular upward rotation, with use of a digital inclinometer.Hypothesis/Purpose:
The objective of this study was to determine the criterion‐related validity of a modified digital inclinometer when used to measure the motion of scapular anterior‐posterior (AP) tilt.Materials & Methods:
Thirteen volunteers, free from any history of shoulder injury, reported for a single testing session. Each subject underwent a brief shoulder and posture examination in order to confirm the absence of pathology. Subjects actively performed clinically relevant amounts of humeral elevation in the scapular plane while in a seated position. An electromagnetic tracking system (Ascension Technology, Burlington, VT) and a modified inclinometer (Pro 360, Baseline®, Fabrication Enterprises, White Plains, NY) were used to acquire scapular AP tilt over the same shoulder motions. Criterion‐related validity was determined using Pearson Product Moment correlations.Results:
Correlation analyses revealed significant moderate to good associations (r = 0.63 to 0.86, p < 0.01) between scapular AP tilt measures obtained with a digital inclinometer and an electromagnetic tracking system.Conclusions
A modified digital inclinometer is a moderately valid device to use for the quantification of scapular AP tilt. Further study is warranted to establish reliability and to validate use of the device in patients with shoulder injury or pathology. The modified inclinometer expands the clinician''s ability to quantify scapular kinematic motion during the clinical evaluation and rehabilitation process.Level of Evidence:

Background:
Alterations in scapular and glenohumeral kinematics in patients with shoulder dysfunction have been recognized by this studies authors'' and described in multiple other studies available in the literature. A reliability study was developed to assess a new technique for measuring scapulohumeral kinematics. Previous scapular position measuring techniques may require expensive equipment which decreases clinical utility. Other techniques require identification of multiple anatomic landmarks that may decrease accuracy, precision, and reliability.Methods:
A sample of asymptomatic controls and symptomatic study subjects were recruited. Each subject had markers placed on each acromion and stood at a standardized distance in front of a light. The shadow projected from the acromial marker onto a standardized, data collection board was measured during the resting, flexion, and scaption positions for bilateral shoulders. The horizontal and vertical translations of the shadows were measured compared to the resting point for both flexion and scaption.Results:
The scapula translated superiorly and medially during both flexion and scaption movements in all subjects and controls. There was good inter-rater reliability for measuring scapular translation with scaption (ICC= 0.81) and moderate reliability for measuring scapular translation with flexion (ICC = 0.62). There was increased superior and medial scapular translation in the subjects with flexion (p= 0.004 and p=0.002) and scaption (p= 0.01 and p=0.007) in the symptomatic shoulder compared to the asymptomatic shoulder. Superior scapular translation with flexion (p=0.0003) and scaption (p=0.006) and medial scapular translation with flexion (p<0.0001) and scaption (p<0.0001) was greater in the symptomatic subjects compared to controls.Conclusions:
The scapula translates both superiorly and medially with flexion and scaption in asymptomatic and symptomatic subjects. After shoulder surgery, patients have increased superior and medial translation of the scapula compared to 1) their asymptomatic shoulder and 2) an asymptomatic control group. The current technique has good inter-rater reliability (ICC=0.81) when measuring scaption and moderate reliability when measuring flexion (ICC=0.62).Level of Evidence:

Background
The importance of the scapular stabilizing muscles has led to an increased interest in quantitative measurements of their strength. Few studies have measured isometric or concentric isokinetic forces. Additionally, limited reports exist on the reliability of objective measures for testing scapular protraction and retraction muscle strength or scapular testing that does not involve the glenohumeral joint.Objective
To determine the reliability of four new methods of measuring the maximal isometric strength of key scapular stabilizing muscles for the actions of protraction and retraction, both with and without the involvement of the glenohumeral (GH) joint.Methods
The Isobex® stationary tension dynamometer was used to measure the maximal isometric force (kg) on thirty healthy females (ages 22–26 years). Three measures were taken for each method that was sequentially randomized for three separate testing sessions on three nonconsecutive days.Results
Intraclass correlations (ICC2,3) for intrasession reliability and (ICC3,3) for intersession reliability ranged from 0.95 to 0.98, and 0.94 to 0.96 respectively. The standard errors of measurement (95% confidence interval [CI]) were narrow. Scatter grams for both protraction and retraction testing methods demonstrated a significant relationship, 0.92 for protraction (95% CI 0.83 to 0.96) and 0.93 for retraction (95% CI 0.87 to 0.97). Bland-Altman plots indicated good agreement between the two methods for measuring protraction strength but a weaker agreement for the two methods measuring retraction strength.Discussion/Conclusion
The four new methods assessed in this study indicate reliable options for measuring scapular protraction or retraction isometric strength with or without involving the GH joint for young healthy females. 相似文献4.

Background
Researchers have demonstrated moderate evidence for the use of exercise in the treatment of subacromial impingement syndrome (SAIS). Recent evidence also supports eccentric exercise for patients with lower extremity and wrist tendinopathies. However, only a few investigators have examined the effects of eccentric exercise on patients with rotator cuff tendinopathy.Purpose
To compare the effectiveness of an eccentric progressive resistance exercise (PRE) intervention to a concentric PRE intervention in adults with SAIS.Study Design
Randomized Clinical TrialMethods
Thirty‐four participants with SAIS were randomized into concentric (n = 16, mean age: 48.6 ± 14.6 years) and eccentric (n = 18, mean age: 50.1 ± 16.9 years) exercise groups. Supervised rotator cuff and scapular PRE''s were performed twice a week for eight weeks. A daily home program of shoulder stretching and active range of motion (AROM) exercises was performed by both groups. The outcome measures of the Disabilities of the Arm, Shoulder, and Hand (DASH) score, pain‐free arm scapular plane elevation AROM, pain‐free shoulder abduction and external rotation (ER) strength were assessed at baseline, week five, and week eight of the study.Results
Four separate 2x3 ANOVAs with repeated measures showed no significant difference in any outcome measure between the two groups over time. However, all participants made significant improvements in all outcome measures from baseline to week five (p < 0.0125). Significant improvements also were found from week five to week eight (p < 0.0125) for all outcome measures except scapular plane elevation AROM.Conclusion
Both eccentric and concentric PRE programs resulted in improved function, AROM, and strength in patients with SAIS. However, no difference was found between the two exercise modes, suggesting that therapists may use exercises that utilize either exercise mode in their treatment of SAIS.Level of evidence

Background
With shoulder pain and injury on the rise in overhead athletes, clinicians are often examining preventative exercises to address functional abnormalities. Because shoulder impingement is prevalent in overhead athletes, much focus is on scapular stability and the function of the stabilizing force couple of the upper and lower trapezius and serratus anterior.Hypothesis/Purpose
The purpose of this study was to examine scapular muscle activation during a series of throws and holds (throwing without releasing) with two different ball weights (7oz and 12oz). It was hypothesized that the holds exercises would elicit greater activation of the scapular musculature than the throw, irrespective of ball weight.Study Design
Case control laboratory studyMethods
Twenty-two NCAA Division I, right hand dominant, softball players (19.91 + 1.04 years; 169.24 + 7.36 cm; 72.09 + 10.61 kg) volunteered to participate. Surface EMG was utilized to measure muscle activity in the upper, middle and lower trapezius and serratus anterior muscles during three different throwing activities.Results
MANOVA results revealed no significant differences in muscle activity between throwing conditions, F(16,82) = 1.02, p = 0.446, Wilks’ Λ = 0.696, Cohen''s d = 0.44 (7oz holds), 0.24 (12oz holds), power = 0.625.Conclusion/Clinical Relevance
The results may provide some clinical insight in advocating the use of holds with different ball weights. The holds throw may be an effective step in shoulder strengthening that can more closely mimic the functional movement of throwing without the element of ball release.Levels of Evidence

Purpose/Aim:
This study investigated the intrarater reliability and concurrent validity of active shoulder mobility measurements using a digital inclinometer and goniometer.Materials/Methods:
Two investigators used a goniometer and digital inclinometer to measure shoulder flexion, abduction, internal and external rotation on 30 asymptomatic participants in a blinded repeated measures design.Results:
Excellent intrarater reliability was present with Intraclass Correlation Coefficients (ICC- 3,k) for goniometry ≥ 0.94 and digital inclinometry ≥ 0.95. The concurrent validity between goniometry and digital inclinometry was good with ICC (3,k) values of ≥ 0.85. The 95% limits of agreement suggest that the difference between these two measurement instruments can be expected to range from 2° to 20°.Conclusions:
The results cautiously support the interchangeable use of goniometry and digital inclinometer for measuring shoulder mobility measurements. Although reliable, clinicians should consider the 95% limits of agreement when using these instruments interchangeably as clinically significant differences are likely to be present.Level of evidence:

Background
The significance of scapular dyskinesis is being challenged due to a lack of the association with pain and ability to predict injury in athletic populations. However, it is unknown whether asymptomatic overhead athletes with dyskinesis cope by normalizing scapular position with higher demand activities.Hypothesis/Purpose
The purpose of this study was to compare change in scapular kinematics from an active unweighted contraction to a maximal isometric contraction in asymptomatic overhead athletes with and without scapular dyskinesis. Secondarily, force generated with manual muscle tests were explored for differences and relationships with kinematics.Study Design
Cross‐sectional laboratory studyMethods
Twenty‐five matched asymptomatic overhead athletes with (n=14) and without (n=11) scapular dyskinesis, defined with a reliable and validated clinical method, participated in this study. Three‐dimensional scapular kinematics were evaluated in an active unweighted condition, and during maximal isometric contractions at 90 ° of shoulder flexion. Isometric force produced with lower trapezius and serratus anterior manual muscle tests were assessed with a dynamometer. Changes in scapular kinematics were compared between groups. Differences in force generated with manual muscle tests between groups and relationships with kinematics were explored.Results
Athletes with dyskinesis demonstrated greater deficits in scapular upward rotation with maximal contraction (p=<0.001), less external rotation (p=0.036) and weaker lower trapezius manual muscle test strength (p=0.031). Lower trapezius (p=0.003;r=0.57) and serratus anterior (p=0.042;r=0.41) manual muscle test strength deficits were fair to moderately associated with a lack of scapular upward rotation during maximal contraction.Conclusion
Small to moderate changes in scapular kinematics are normal responses to a maximal contraction, but with scapular dyskinesis this response is accentuated. Athletes with dyskinesis generate less force with lower trapezius manual muscle testing compared to athletes without dyskinesis. Decreased strength with lower trapezius and serratus anterior manual muscle testing was also related to a lack of upward rotation in all athletes.Level of Evidence

Background:
Rehabilitative ultrasound Imaging (RUSI) is increasingly used in the management of musculoskeletal conditions as it provides an objective measure of muscle function while being less invasive than needle electromyography. While research has documented the ability to reliably measure trunk muscles in patients with back pain, no study to date has used RUSI to quantify infraspinatus muscle function in patients with shoulder impingement syndrome (SIS).Hypothesis/Purpose:
The purpose of this study was to examine the intra‐rater and inter‐rater reliability of measuring infraspinatus muscle thickness with RUSI and to compare such measures during resting versus contracted muscle states and in the symptomatic versus asymptomatic shoulders in patients with SIS.Study Design:
Cross‐sectional, measurement studyMethods:
Fifty‐two participants with unilateral SIS underwent a standard baseline examination to include RUSI of the infraspinatus muscle bilaterally. Images were acquired at rest and during a submaximal isometric contraction, by two novice examiners. The isometric contraction was elicited by having prone participants externally rotate their shoulder from a position of 90° abduction into a dynamometer and hold a static force of 20 mmHg (approximately 20‐30% maximal voluntary contraction). Images were captured using a standardized placement of the transducer placed just inferior to the spine of the scapula along the medial scapular border and measured off‐line using Image J software (V1.38t, National Institutes of Health, Bethesda, Maryland).Results:
Estimates (ICCs) for thickness measurements ranged between 0.96 and 0.98 for intra‐rater reliability and between 0.87 and 0.92 for inter‐rater reliability. Reliability was substantially lower (ICC = 0.43 to 0.79) for calculations of percent thickness change. The infraspinatus muscle was significantly thicker when contracted (19.1mm) than during rest (16.2mm) in both shoulders (p < 0.001). There was also a statistically significant interaction between contraction state and shoulder (p = 0.026), indicating that the change in thickness that occurred during contraction was significantly smaller in the symptomatic shoulder than in the asymptomatic shoulder.Conclusion:
RUSI measurements of infraspinatus muscle thickness appear to be highly reliable, both within the same examiner and between different examiners, in patients with SIS. Moreover, such measurements were different in rested and contracted states of the infraspinatus, as well as, between the symptomatic and asymptomatic shoulders of patients with unilateral SIS.Level of evidence:

Background
Upper extremity physical performance measures exist but none have been universally accepted as the primary means of gauging readiness to return to activity following rehabilitation. Few reports have described reliability and/or differences in outcome with physical performance measures between individuals with and without shoulder symptoms.Hypotheses/Purpose
The purpose of this study was to establish the reliability of traditional upper extremity strength testing and the CKCUEST in persons with and without shoulder symptoms as well as to determine if the testing maneuvers could discriminate between individuals with and without shoulder symptoms. The authors hypothesized that strength and physical performance testing would have excellent test/re‐test reliability for individuals with and without shoulder symptoms and that the physical performance maneuver would be able to discriminate between individuals with and without shoulder symptoms.Methods
Male and female subjects 18‐50 years of age were recruited for testing. Subjects were screened and placed into groups based on the presence (Symptomatic Group) or absence of shoulder symptoms (Asymptomatic Group). Each subject performed an isometric strength task, a task designed to estimate 1‐repetition maximum (RM) lifting in the plane of the scapula, and the closed kinetic chain upper extremity stability test (CKCUEST) during two sessions 7‐10 days apart. Test/re‐test reliability was calculated for all three tasks. Independent t‐tests were utilized for between group comparisons to determine if a performance task could discriminate between persons with and without shoulder symptoms.Results
Thirty‐six subjects (18/group) completed both sessions. Test/re‐test reliability for each task was excellent for both groups (intraclass correlations ≥ .85 for all tasks). Neither strength task could discriminate between subjects in either group. Subjects with shoulder symptoms had 3% less touches per kilogram of body weight on the CKCUEST compared to subjects without shoulder symptoms but this was not statistically significantly different (p=.064).Conclusions
The excellent test/re‐test reliability has now been expanded to include individuals with various reasons for shoulder symptoms. Traditional strength testing does not appear to be the ideal assessment method for making discharge and/or return to activity decisions due to the inability to discriminate between the groups. The CKCUEST could be utilized to determine readiness for activity as it was trending towards being discriminatory between known groups.Level of Evidence

Objective
The purpose of this study was to examine the validity and test–retest reliability of the ScreenAssist Lumbar Questionnaire (SALQ). If a high degree of reliability and validity could be determined, the questionnaire could provide physical therapists with a formal instrument to assist with the identification of patients with nonmusculoskeletal back pain or emergent musculoskeletal causes of back pain requiring referral to an alternate medical provider.Methods
Participants were patients presenting to an internal medicine physician''s office with the main complaint of low back pain over a 6 months period. ScreenAssist Lumbar Questionnaire was performed twice on each patient within 48 hours of the appointment. A 4-month post-visit chart review was performed to compare scores and recommendations made by the questionnaire with the assessment and diagnosis made by the physician.Results
The SALQ demonstrated a sensitivity of 0·100 (95% CI: 0·689–0·100) and specificity of 0·786 (95%CI: 0·492–0·951) compared to the assessment and diagnosis performed by the primary care physician. Overall, regarding the recommendation for referral, there was agreement on 20 of the 21 patients with a Kappa of 0·798.Discussion
The overall test–retest reliability and validity for referral recommendation were high, which indicates that the SALQ may serve as an alternative to the use of red flags in isolation to assist the physical therapist in determining the need for medical referral as the practice continues to progress toward direct access. The positive outcome of this study supports the possible future benefit of the SALQ. 相似文献13.

Purpose/Background:
Side to side asymmetry in glenohumeral joint rotation correlates with injury risk in overhead athletes. The purpose of the current study was to identify the relationship between side‐to‐side asymmetries in glenohumeral joint total rotational range of motion and shoulder mobility test scores from the Functional Movement Screen™ in collegiate overhead athletes. The authors hypothesized that asymmetries of > 10° in glenohumeral total rotation would not be associated with asymmetrical findings in the Functional Movement Screen™ (FMS) shoulder mobility test.Methods:
Passive glenohumeral total rotational range of motion and the shoulder mobility test of the FMS were measured during pre‐participation examinations in 121 NCAA male and female Division II collegiate overhead athletes from varied sports. Passive shoulder range of motion was measured in supine at 90° of abduction, with the humerus in the scapular plane using two measurers and a bubble goniometer. A Pearson Chi‐square analysis, p<.05 was used to associate the presence of asymmetries in glenohumeral joint rotation and in the FMS shoulder mobility test in each subject.Results:
40/114 (35.1%) athletes demonstrated asymmetries in total glenohumeral rotation. 45/114 (39.5%) athletes demonstrated asymmetries in the shoulder mobility test. Only 17 of the 45 subjects who demonstrated asymmetry on the shoulder mobility test also demonstrated glenohumeral joint rotation differences of > 10°. Athletes with asymmetries in rotation of > 10° were not any more likely to have asymmetries identified in the shoulder mobility test (95% CI=.555‐2.658, P=.627).Conclusions
Glenohumeral joint range of motion is one of multiple contributors to performance on the FMS shoulder mobility test, and alone, did not appear to influence results. The FMS shoulder mobility test should not be used alone as a means of identifying clinically meaningful differences of shoulder mobility in the overhead athlete. Clinicians working with overhead athletes may consider using both assessments as a complete screening tool for injury prevention measures.Level of Evidence:

Background:
The lack of proper scapular kinematics can limit the function of the entire shoulder complex.1,3 Many forms of scapular dyskinesis have been proposed along with tests to measure for the position and motion associated with those positional and movement faults (2,4-6). While scapular internal rotation has been listed among the forms of scapular dyskinesis there has not been a reliable test documented in the literature that examines this motion. The purpose of this study was to determine whether an innovative scapular medial border posterior displacement measurement device has adequate inter-rater and intra-rater reliability when used at rest and during the sitting hand press up test.Methods:
16 male Division III baseball players free of upper limb injury for the previous 12 months participated in the study. Posterior scapular displacement measures were taken on each subject in a resting static posture and while performing a sitting hand press up test. Subjects were tested twice within 24 hours by two separate examiners. Intraclass correlation coefficients (ICC) were calculated to determine intra-rater and inter-rater reliability.Results:
The intra-rater reliability for rater 1 was .97 (95% confidence interval [CI]= .91-.98), for the rest position and .95 (95% CI= .86-.98) for the sitting hand press-up position. Intra-rater reliability for rater 2 was .99 (95% CI= .97-.99) for the rest position and .98 (95% CI=. 95-.99) for the sitting hand press-up position. The ICCs for inter-rater reliability of the scapular medial border posterior displacement measurement in at the rest position and the sitting hand press-up position were .89 (95% CI= .81-.96) and .89 (95% CI= .80-.96) respectively.Conclusions:
The findings of this study indicate that the measurement of medial border posterior displacement using this device demonstrates good to excellent inter-rater and intra-rater reliability. 相似文献15.

Background
The Advanced Throwers Ten Exercise Program incorporates sustained isometric contractions in conjunction with dynamic shoulder movements. It has been suggested that incorporating isometric holds may facilitate greater increases in muscular strength and endurance. However, no objective evidence currently exists to support this claim.Hypothesis/Purpose
The purpose of this research was to compare the effects of a sustained muscle contraction resistive training program (Advanced Throwers Ten Program) to a more traditional exercise training protocol to determine if increases in shoulder muscular strength and endurance occur in an otherwise healthy population. It was hypothesized that utilizing a sustained isometric hold during a shoulder scaption exercise from the Advanced Throwers Ten would produce greater increases in shoulder strength and endurance as compared to a traditional training program incorporating a isotonic scapular plane abduction (scaption) exercise.Study Design
Randomized Clinical Trial.Method
Fifty healthy participants were enrolled in this study, of which 25 were randomized into the traditional training group (age: 26 ± 8, height:172 ± 10 cm, weight: 73 ± 13 kg, Marx Activity Scale: 11 ± 4) and 25 were randomized to the Advanced Throwers Ten group (age: 28 ± 9, height: 169 ± 23 cm, weight: 74 ± 16 kg, Marx Activity Scale: 11 ± 5). No pre‐intervention differences existed between the groups (P>0.05). Arm endurance and strength data were collected pre and post intervention using a portable load cell (BTE Evaluator, Hanover, MD). Both within and between group analyses were done in order to investigate average torque (strength) and angular impulse (endurance) changes.Results
The traditional and Advanced Throwers Ten groups both significantly improved torque and angular impulse on both the dominant and non‐dominant arms by 10–14%. There were no differences in strength or endurance following the interventions between the two training groups (p>0.75).Conclusions;
Both training approaches increased strength and endurance as the muscle loads were consistent between protocols indicating that either approach will have positive effects.Level of Evidence

Background
Previous studies have shown military physical therapists (PT) to have comparable clinical diagnostic accuracy (CDA) and interobserver agreement to orthopaedic surgeons (OS). However, no studies have examined hip pathology or used intraoperative findings as the reference standard for diagnosis.Objective
To compare the CDA of physical examination findings among a PT, an OS, and two surgical orthopaedic residents (ORs) for hip labral tears.Methods
Thirty-six patients (15 males, 21 females) aged 18–47 (mean + SD, 31.4 + 8.1 years) with 37 symptomatic hips were enrolled in a prospective study and underwent a standardized clinical examination followed by hip arthroscopy. A PT, an OS, and two ORs independently performed history and examinations with the emphasis of diagnosis on the results of six special tests.Results
Thirty-two of 37 individuals (86%) had labral tears to the hip at arthroscopy. Analysis of agreement between clinical diagnosis and intra-operative findings of a labral tear produced a CDA of 85.3% (29/34 correct) for the PT, 84.4% (27/32 correct) for the OS, and 80.0% (24/30 correct) for ORs. No significant difference in CDA occurred in comparing the PT, OS, and ORs.Conclusions
Using arthroscopy as the reference standard, hip labral tears were clinically suspected with 80–85% accuracy. The clinical diagnostic accuracy of the PT, OS, and ORs was high with no significant difference between examiners. In this study, an experienced PT, an OS, and two ORs demonstrated similarly high diagnostic skills. 相似文献17.

Background/Purpose:
Movement ability is an often‐overlooked component of sports science and sports medicine research and needs to be considered alongside the appraisal of physical fitness and performance characteristics. To achieve this, a standardised assessment tool is required. The purpose of this paper is to introduce a new method for assessing movement ability and present results for intra‐ and inter‐rater reliability.Methods:
National level female football players (n=17) were assessed using a novel movement assessment tool, the Athletic Ability Assessment (AAA). Athletes were assessed according to the scoring criteria by the primary researcher in real‐time and via video on two separate occasions to estimate intra‐tester reliability. Inter‐tester reliability was estimated using the difference between five other testers'' video‐based scores.Results:
The intra‐tester minimal detectable change (MDC) for the composite AAA score was 2.9 points (90% confidence limits; 2.3 – 4.2 points) (2.5%; 2.0 – 3.6%) with an intraclass correlation coefficient (ICC) of 0.97 (0.92 – 0.99). Inter‐tester MDC for the composite AAA score was 2.8 points (2.5 – 3.3 points) (2.4%; 2.1 – 2.8%) with an ICC 0.96 (0.94 – 0.98) Individual exercise scores for the intra‐ and inter‐tester show a similar range MDC of between 0.4 – 1.1 points and kappa statistic level of agreement between 0.32 ‐0.77.Conclusions:
Results of the reliability analysis suggest high levels of agreement between scorers for total scores and provide reference values for minimal detectable changes using the AAA. The aim of the AAA is to become a reliable movement assessment protocol that addresses specific sporting populations. The reliability of AAA scoring established in this study is the first step in supporting the utilization of the AAA in future research.Level of evidence:

Background
Interpretation of Lachman testing when evaluating the status of the anterior cruciate ligament (ACL) typically includes a numerical expression classifying the amount of translation (Grade I, II, III) in addition to a categorical modifier (Grade A [firm] or B [absent]) to describe the quality of the passive anterior tibial translation''s endpoint. Most clinicians rely heavily on this tactile sensation and place value in this judgment in order to render their diagnostic decision; however, the reliability and accuracy of this endpoint assessment has not been well established in the literature.Purpose
The purpose of this study was to determine the intertester reliability of endpoint classification during the passive anterior tibial translation of a standard Lachman test and evaluate the classification''s ability to accurately predict the presence or absence of an ACL tear.Study design
Prospective, blinded, diagnostic reliability and accuracy study.Methods
Forty‐five consecutive patients with a complaint of knee pain were independently evaluated for the endpoint classification during a Lachman test by two physical therapists before any other diagnostic assessment. The 21 men and 24 women ranged in age from 20 to 64 years (mean +/‐ SD age, 40.7 +/‐ 14) and in acuity of knee injury from 30 to 365 days (mean +/‐ SD, 238 +/‐157).Results
17 of the 45 patients had a torn ACL. The agreement between examiners on A versus B endpoint classification was 91% with a kappa coefficient of 0.72. In contrast, classification agreement based on the translational amount had an agreement of 65% with a weighted kappa coefficient of 0.52. The sensitivity of the endpoint grade alone was 0.81 with perfect specificity resulting in a positive likelihood ratio of 6.2 and a negative likelihood ratio of 0.19. The overall accuracy of the Lachman test using the endpoint assessment grade alone was 93% with a number needed to diagnose of 1.2.Conclusions
Nominal endpoint classification (A or B) from a Lachman test is a reliable and accurate reflection of the status of the ACL. The true dichotomous nature of the test''s interpretation (positive vs. negative) is well‐served by the quality of the endpoint during passive anterior tibial translation.Level of Evidence
