Reliability of new radiographic measurement techniques for elbow bony impingement

Abstract Background Identifying the location and scale of radiographic changes in elbow bony impingement (EBI) is critical in formulating an appropriate diagnosis and treatment plan for such patients. The purpose of present study was to evaluate the intra-rater and inter-rater reliability of the new radiographic parameters, Anterior Impingement angle (AIa) and Posterior Impingement angle (PIa), for EBI. In addition, to determine if there was a relationship between radiographic parameters and clinical evaluation. Patients and methods Three raters of different levels of training evaluated the radiographs of 60 patients (30 in EBI group and 30 in normal group) twice, at least 2 weeks apart. Intra-rater and inter-rater reliabilities were calculated by Intraclass Correlation Coefficients (ICC) with 95% confidence intervals. Correlation between radiographic parameters and clinical evaluation was calculated by Pearson correlation coefficient. Results In both groups, intra-rater and inter-rater reliabilities were substantial. There were no significant differences in reliability between upper-hand expert surgeons and resident for either measurement. Good correlation was observed between impingement arcs and range of motion values. Conclusions Both AIa and PIa measurements demonstrated substantial intra-rater and inter-rater reliability for normal radiographs and in EBI patients. Good reliability, for either expert surgeons or residents in training, and good correlation between radiographic measurements and manual testing, appoints this method may be easily and reliably used in every day practice.

Key Characteristics

ABSTRACT THE EVALUATION AND treatment of spinal deformities begins with the accurate measurement of appropriate spinal parameters. The surgeon must ensure that the patient is positioned properly for all necessary x-ray scans and that the proper studies are completed. The relevant measurements must be identified and recorded for each study. Understanding the proper measurement techniques will increase the accuracy and reliability of the measurements. From these precise measurements the surgeon can begin to determine key characteristics of the deformity and develop an appropriate treatment plan.

Background: Cricket bowling involves combined spinalmovements of side bending and rotation and, consequently, injuryto the low back is a common problem. Therefore the assessmentof lumbar spine kinematics has become a routine component inpreseason screening. This includes static measurement of lateralspinal flexion as asymmetrical range of motion may predispose anathlete to low back injury.Objectives: This study examined intra-rater reliability andconcurrent validity of the fingertip-to-floor distance test (FFD)when compared to a criterion range of motion measure.Methods: Thirty-four junior-level cricket players aged 13‑16years were recruited. Lumbar spine lateral flexion was measuredsimultaneously with the fingertip-to-floor distance test and digitalinclinometry methods. Relative and absolute intra-rater reliabilitywere investigated with intraclass correlation coefficients (ICC3,1)of agreement, standard error of measurement (SEM) estimates,Bland and Altman bias estimates and 95% limits of agreement,respectively. The concurrent validity of the fingertip-to-floordistance test, compared to digital inclinometry measures, wasexamined with Pearson correlation coefficients.Results: Intra-rater reliability demonstrated substantial agreementfor both measures (ICC3,1 > 0.84). The fingertip-to-floor distancetest SEM values ranged from 1.71‑2.01 cm with an estimatedminimum detectable change (MDC) threshold of 4.73‑5.55 cm.The inclinometry SEM values ranged from 1.00‑1.09° withminimal detectable change estimates of 2.77‑3.01°. There werestrong correlations between the index test and criterion measureoutcomes (r > 0.84, p < 0.001).Conclusions: This study’s results support the intra-rater reliabilityand concurrent validity of the finger-to-floor distance test,suggesting it to be a suitable surrogate measure for lumbar lateralflexion testing

Healthy Participants

Background Several water-based sports (swimming, surfing and stand up paddle boarding) require adequate thoracic mobility (specifically rotation) in order to perform the appropriate activity requirements. The measurement of thoracic spine rotation is problematic for clinicians due to a lack of convenient and reliable measurement techniques. More recently, smartphones have been used to quantify movement in various joints in the body; however, there appears to be a paucity of research using smartphones to assess thoracic spine movement. Therefore, the aim of this study is to determine the reliability (intra and inter rater) and validity of the iPhone® app (Compass) when assessing thoracic spine rotation ROM in healthy individuals. Methods A total of thirty participants were recruited for this study. Thoracic spine rotation ROM was measured using both the current clinical gold standard, a universal goniometer (UG) and the Smart Phone Compass app. Intra-rater and inter-rater reliability was determined with a Intraclass Correlation Coefficient (ICC) and associated 95% confidence intervals (CI). Validation of the Compass app in comparison to the UG was measured using Pearson’s correlation coefficient and levels of agreement were identified with Bland–Altman plots and 95% limits of agreement. Results Both the UG and Compass app measurements both had excellent reproducibility for intra-rater (ICC 0.94–0.98) and inter-rater reliability (ICC 0.72–0.89). However, the Compass app measurements had higher intra-rater reliability (ICC = 0.96 − 0.98; 95% CI [0.93–0.99]; vs. ICC = 0.94 − 0.98; 95% CI [0.88–0.99]) and inter-rater reliability (ICC = 0.87 − 0.89; 95% CI [0.74–0.95] vs. ICC = 0.72 − 0.82; 95% CI [0.21–0.94]). A strong and significant correlation was found between the UG and the Compass app, demonstrating good concurrent validity (r = 0.835, p < 0.001). Levels of agreement between the two devices were 24.8° (LoA –9.5°, +15.3°). The UG was found to consistently measure higher values than the compass app (mean difference 2.8°, P < 0.001). Conclusion This study reveals that the iPhone® app (Compass) is a reliable tool for measuring thoracic spine rotation which produces greater reproducibility of measurements both within and between raters than a UG. As a significant positive correlation exists between the Compass app and UG, this supports the use of either device in clinical practice as a reliable and valid tool to measure thoracic rotation. Considering the levels of agreement are clinically unacceptable, the devices should not be used interchangeably for initial and follow up measurements.

Abstract Background: The Foot Posture Index (FPI-6) is a validated and rapid clinical method for evaluating standing foot posture through assessing six individual criteria. Although it has been widely used without radiographic examination, evidences for correlation of FPI-6 with radiographic parameters remain scanty. The objective of this study is to investigate the correlation of FPI-6 with radiographic measurements and to assess the feasibility of FPI-6 for clinical evaluation of standing foot postures. Methods: Sixty patients (M:F,33:27, mean age 62 ) of foot and ankle symptoms and 40 asymptomatic male volunteers (age, 20-28), were included in this study. FPI-6 scores were evaluated by 4 raters and inter-rater reliability of FPI-6 was assessed by intraclass correlation coefficient (ICC). Radiologic measurements including talo-first metatarsal angle (TMA), Meary’s angle (MA), talonavicular coverage angle (TNCA), talocalcaneal angle (TCA), calcaneal pitch angle (CPA), and hindfoot alignment angle (HAA) were measured. For the correlation analysis between FPI-6 and radiographic parameters, statistical analysis was performed using Pearson’s correlation test.Results: Inter-rater reliability was ‘high to excellent’ among raters. However, FPI-6 score was more repeatable in patients group and in more experienced raters. In total group, FPI-6 score was correlated with TNCA, TMA, lateral TCA, MA, and HAA. Especially, TNCA and HAA were more strongly correlated among them. When we analyzed the subdomains of FPI-6, the congruence of the medial longitudinal arch and the prominence in the region of the talonavicular joint were most strong indicators for TNCA and HAA, respectively. Conclusion: This study manifested that not only the feasibility of the FPI-6, but also its correlation to radiographic parameters, is significant for both the patients and the asymptomatic group. We assert that FPI-6 scoring system can be used as a first-line tool for foot posture assessment in clinics without radiographic evaluation if used carefully.

OBJECTIVEGrabb’s line—the perpendicular distance from the basion-C2 line (pB-C2)—is a widely used radiographic measurement with significant clinical implications in patients with a complex Chiari malformation. Rigorous demonstration of the reproducibility of this measurement has not previously been reported. The authors report a standardized measurement technique with excellent inter- and intrarater reliability on T1-weighted sagittal MRI.METHODSThe authors developed a standardized measurement technique that included specifications of midline slice selection, landmark and reference line definitions, and measurement technique on T1-weighted sagittal images. Twenty MR images were reviewed by 2 pediatric neurosurgeons, 1 pediatric radiologist, and 1 undergraduate student. Measurements were performed using the technique specified on 2 separate occasions. Intrarater and interrater reliabilities were calculated using the intraclass correlation coefficient.RESULTSA combined interrater reliability of 0.879 was achieved for the pB-C2, and 0.916 for the clival-canal angle, another measure of interest in patients with complex Chiari malformations. Intrarater reliability for these measurements exceeded 0.858 for all 4 reviewers.CONCLUSIONSGrabb’s line—the pB-C2—can be measured with excellent reliability using a standardized measurement protocol. Individual clinicians and collaborative databases should consider using validated measurement techniques to guide clinical decision making in patients with craniocervical junction pathology.

INTRODUCTION We sought to validate radiographic measurements of range of motion of the knee after arthroplasty as part of a new system of virtual clinics. METHODS The range of motion of 52 knees in 45 patients was obtained by 2 clinicians using standardised techniques and goniometers. Inter-rater reliability and intraclass correlation coefficients (ICCs) were calculated. Radiographs of these patients’ knees in full active flexion and extension were also used to calculate intra and inter-rater reliability compared with clinical measurements using four different methods for plotting angles on the radiographs. RESULTS The ICC for inter-rater reliability using the goniometer was very high. The ICC was 0.91 in extension and 0.85 in flexion while repeatability was 8.49° (-8.03–8.99°) in extension and 5.23° (-4.54–5.74°) in flexion. The best ICC for radiographic measurement in extension was 0.86, indicating ‘near perfect’ agreement, and repeatability was 5.43° (-4.04–6.12°). The best ICC in flexion was 0.95 and repeatability was 5.82° (-3.38–6.55°). The ICC for intrarater reliability was 0.98 for extension and 0.99 for flexion on radiographic measurements. CONCLUSIONS Validating the use of radiographs to reliably measure range of motion following knee arthroplasty has allowed us to set up a ‘virtual knee clinic’. Combining validated questionnaires and radiographic measurement of range of motion, we aim to maintain high quality patient surveillance following knee arthroplasty, reduce our ratio for new to follow-up patients in line with Department of Health guidelines and improve patient satisfaction through reduced travel to hospital outpatients.

New Perspective

Changes in balance are observed in some hemiparetics following a stroke, generating significant physical, social, and economic impacts; thus, an assessment was developed to facilitate treatment plans for patients. Goniometry is currently used as an evaluation tool for range of motion (ROM); however, the development of exergames has brought a new perspective to the assessment, which uses a dynamic mechanism and has little subjectivity. Objective: This study evaluates the inter-and intra-rater reliability of ROM measurement of the shoulder abduction in post-stroke patients using the exergame PhysioPlay™. Method: Thirteen volunteer chronic stroke survivors, aged 58.23 ± 9.96 years (men and women), participated in this study. Two physiotherapists evaluated the abduction of the shoulder using goniometry and the exergame PhysioPlay™. A retest was performed one week later. Clinical trial registry number – RBR-55smwr. Results: The results of the analyses using intraclass correlation coeficient (ICC) showed an excellent inter- and intra-rater reliability level (r > 0.90; p < .05). The Pearson correlation between the maximum measures obtained in the goniometry and the software PhysioPlay™ showed a high correlation (r > 0.90, p= .001). Conclusion: The Kinect associated with the exergame PhysioPlay™ presented excellent reliability in capturing the ROM measure compared to the conventional goniometry.

Implant Stability Quotient

Background: Actually, resonance frequency analysis (RFA) is the most extended method for measuring implant stability. The implant stability quotient (ISQ) is the measure obtained by the different RFA devices, however, inter- and intra- rater reliability and validity of some devices remains unknown. Methods: Thirty implants were placed in 3 different pig mandibles. ISQ was measured axial and parallel with Osstell® Beacon, Penguin® and MegaISQ® by 2 different operators and one operator performed a test-retest. Intraclass correlation coefficient was calculated to assess the intra- and inter-rater reliability. Pearson correlation coefficient was used to assess the validity. Results: The higher inter- and intra- rater reliability was obtained by Penguin® when measuring axial. The highest ISQ values were obtained using Penguin® in an axial measurement; the lowest, using the MegaISQ® in an axial measurement. The highest correlation values with the other devices were obtained by MegaISQ® measuring axially. Conclusion: Penguin® had a good reliability for measuring ISQ both inter- and intra- rater. Osstell® had good validity for measuring ISQ both axial and parallel and MegaISQ® had the best validity for measuring ISQ axial.

Objective. To investigate the intra- and inter-rater reliability of three measurements on painful and pain-free sides in participants with chronic low back pain (CLBP) at different ages. Methods. We recruited 60 participants with CLBP and divided them equally into a group of younger participants with chronic low back pain (18 ≤ age ≤ 35, Y-CLBP) and a group of older participants with chronic low back pain (36 ≤ age ≤ 65, O-CLBP). Participants were assessed by two testers within the same day (10 min interval), and one of the testers repeated the assessment program 24 h later. The intraclass correlation coefficient (ICC) was used to assess reliability. The Pearson correlation coefficient was used to analyze the correlation between tactile acuity and age, waistline, and pain-related variables. Results. In the Y-CLBP group, the intra-rater reliability of two-point discrimination (TPD), point-to-point test (PTP), and two-point estimation (TPE) on the painful and pain-free sides was good (ICC range: 0.74–0.85), whereas the inter-rater reliability of TPD, PTP, and TPE on the painful and pain-free sides was moderate to good (ICC range: 0.65–0.76). In the O-CLBP group, the intra-rater reliability of TPD, PTP, and TPE on the painful and pain-free sides was good (ICC range: 0.75–0.85), whereas the inter-rater reliability of TPD, PTP, and TPE on the painful and pain-free sides was moderate to good (ICC range: 0.70–0.85). Age, waistline, duration of pain, maximum pain, general pain, and unpleasant score caused by pain were positively correlated with tactile acuity thresholds (D-TPD, A-TPD, PTP, and TPE) (r > 0.365, p < 0.05 ). When BMI was controlled, age, waistline, and pain-related variables were positively correlated with tactile acuity thresholds (r > 0.388; p < 0.05 ). Conclusion. In the participants of Y-CLBP and O-CLBP groups, TPD, PTP, and TPE have moderate-to-good intra- and inter-rater reliability on the painful and pain-free sides of the fifth lumbar vertebrae.

Resonance frequency analysis (RFA) is the most extended method for measuring implant stability. The implant stability quotient (ISQ) is the measure obtained by different RFA devices; however, inter- and intra-rater reliability and agreement of these instruments remain unknown. Thirty implants were placed in three different pig mandibles. ISQ was measured parallel and perpendicular (lingual) to the peg axis with Osstell® Beacon, Penguin® and MegaISQ® by two different investigators and furthermore, one performed a test-retest. Intraclass correlation coefficient was calculated to assess the intra- and inter-rater reliability. Pearson correlation coefficient was used to assess the agreement. Intraclass correlation coefficients ranged from 0.20 to 0.65 for the Osstell® Beacon; 0.57 to 0.86 for the Penguin®; and −0.01 to 0.60 for the MegaISQ®. The highest ISQ values were obtained using Penguin® (66.3) in a parallel measurement; the lowest, using the MegaISQ® (60.1) in a parallel measurement. The highest correlation values with the other devices were obtained by MegaISQ® in a parallel measurement. Osstell® Beacon and MegaISQ® showed lower reliability than Penguin®. Osstell® had good agreement for measuring ISQ both in parallel and perpendicular, and MegaISQ® had the best agreement for measuring ISQ in parallel.
