Ultrasound of median and ulnar nerves in the distal arm of healthy volunteers- inter- and intra rater reliability

Abstract Background The accurate assessment of distal radioulnar joint (DRUJ) instability is still challenging as there is no established objective evaluation method. This study aimed to develop a noninvasive measurement method using a three-dimensional electromagnetic sensor system (EMS) to quantitatively assess and characterize the normal DRUJ movement in healthy volunteers. Methods The DRUJ movement was mimicked using both a block model and saw bone. Movement of the models was measured by EMS, and the accuracy and reproducibility of the measurements were assessed. The movement was evaluated in 14 healthy volunteers (7 men and 7 women) by three hand surgeons. Measurement was done in a sitting position with the elbow flexed and the forearm pronated. One sensor each was attached to the distal radial shaft and the ulnar head. The examiners fixed the distal radius and moved the ulnar head from the dorsal to the volar side, measuring the dorsovolar ulnar head translation. The intraclass and interrater correlation coefficients (ICCs) were calculated using the average values of the measurements. The differences between the dominant and non-dominant sides and between men and women were also assessed. Results The accuracy and reproducibility assessment results of the EMS showed high accuracy and reproducibility. The ICC (1,5) for the intra-rater reliability was 0.856, and the ICC (2,5) for inter-rater reliability was 0.868. The mean ulnar head translation and difference between dominant and non-dominant sides were 6.00 ± 1.16 mm (Mean ± SD) and -0.12 ± 0.40 mm, respectively. There were no significant differences between any of the parameters.Conclusions A new measurement method using EMS could evaluate DRUJ movement with high accuracy, reproducibility, and intra- and inter-rater reliability. In healthy volunteers, the dorsovolar ulnar head translation was 6.00 mm. The difference between the dominant and non-dominant sides was < 1.0 mm with no significant difference. EMS provided an objective, non-invasive, real-time assessment of dynamic changes in the DRUJ. These findings could be useful in the treatment of patients with DRUJ instability.

Background and Objectives: Within the clinical evaluation of multiple pathologies of the lower limb, the measurement of range of motion (ROM) of its joints is fundamental. To this end, there are various tools, from the goniometer as a reference to more recent devices such as inclinometry-based applications, photo capture applications, or motion capture systems. This study aimed to assess the validity, intra-rater, and inter-rater reliability of the VeloFlex system (VS), which is a new camera-based tool designed for tracking joint trajectories and measuring joint ROM. Materials and Methods: Thirty-five healthy volunteers (16 females; aged 18–61 years) participated in this study. All participants were assessed on two separate occasions, one week apart. During the first assessment session, measurements were obtained using a goniometer and the VS, whereas, in the second session, only the VS was used. In each assessment session, nine active movements were examined. For each movement, three trials were tested, and the mean of these three measures was used for analysis. To evaluate the concurrent validity and agreement, the Pearson correlation coefficient (r) and Bland-Altmann plots were used. Intra-rater and inter-rater reliability were evaluated using intra-class correlation (ICC), standard error of measurement (SEM), and minimal detectable change (MDC). Results: Both devices showed excellent correlations for all movements (r ranged from 0.992 to 0.999). The intra-rater reliability of the VS was excellent (ICC ranged from 0.93 to 0.99), SEMs ranged from 0.53% to 2.61% and the MDC ranged from 0.68° to 3.26°. The inter-rater reliability of the VS was also excellent (ICC ranged from 0.88 to 0.98), SEMs ranged from 0.81% to 4.76% and the MDC ranged from 2.27° to 4.42°. Conclusions: The VS is a valid and reliable tool for the measurement of ROM of lower limb joints in healthy subjects.

This study aimed to develop a noninvasive measurement method using a three-dimensional electromagnetic sensor system (EMS) to quantitatively assess and characterize the normal DRUJ movement in healthy volunteers. Methods The DRUJ movement was mimicked using both a block model and saw bone. Movement of the models was measured by EMS, and the accuracy and reproducibility of the measurements were assessed. In vivo measurement was performed in a sitting position with the elbow flexed and the forearm pronated. One sensor each was attached to the distal radial shaft and the ulnar head. The examiners fixed the distal radius and the carpal bones, moved the ulnar head from the dorsal to the volar side and measured the dorsovolar translation. The volar translation was measured by EMS and ultrasonography, and the correlation coefficient was calculated. The dorsovolar translation was evaluated in 14 healthy volunteers (7 men and 7 women) by three hand surgeons. The intraclass and inter-rater correlation coefficients (ICCs), the differences between the dominant and non-dominant sides and between men and women were assessed. Results The accuracy and reproducibility assessment results of the EMS showed high accuracy and reproducibility. In the comparison between EMS and ultrasonography, the correlation coefficient was 0.920 (p = 0.16 × 10-3). The ICC (1,5) for the intra-rater reliability was 0.856, and the ICC (2,5) for inter-rater reliability was 0.868. The mean ulnar head translation and difference between dominant and non-dominant sides were 6.00 ± 1.16 mm (mean ± SD) and − 0.12 ± 0.40 mm, respectively. There were no significant differences between any of the parameters. Conclusions A new measurement method using EMS could evaluate DRUJ movement with high accuracy, reproducibility, and intra- and inter-rater reliability. In healthy volunteers, the dorsovolar ulnar head translation was 6.00 mm. The difference between the dominant and non-dominant sides was < 1.0 mm with no significant difference. EMS provided an objective, non-invasive, real-time assessment of dynamic changes in the DRUJ. These findings could be useful in the treatment of patients with DRUJ instability.

Pain Pressure Threshold

Background: Although the prevalence of sacroiliac joint (SIJ) pain is relatively high (15 – 30%), there is no unambiguous reference standard to diagnose SIJ pain. Pressure tenderness in the SIJ region is used for diagnostic purposes, but the clinimetric properties of this procedure remain to be determined. Objectives: The aim of this study is to determine the reliability of pain pressure threshold (PPT) measurements in the SIJ region and the difference in PPTs in the SIJ region between healthy volunteers and PPTs in patients with SIJ pain. Study Design: Prospective cohort study. Setting: Outpatient pain clinic VU University Medical Center. Methods: Forty-one healthy volunteers and 31 patients diagnosed with SIJ pain were included. PPTs were obtained from 5 measurement points in the region of the SIJ with a pressure pain algometer using a standardized protocol. The inter-rater reliability of this method was calculated by means of the Intraclass Correlation Coefficients (ICC) of individual assessment performed by 2 individual raters of SIJs of healthy volunteers on both sides. PPTs of healthy volunteers were compared to those of the affected side in patients with SIJ pain. Results: PPT measurement showed moderate to good inter-rater reliability (ICC 0.6 – 0.82).The median PPTs of 5 points was comparable for both sides in healthy volunteers (right: 8.5 kg/cm2 [IQR 6.0 – 10.0]; left 8.3 kg/cm2 (5.8 – 10.0]). Median PPTs for the affected sides of patients with SIJ pain were significantly lower compared to the same side of healthy volunteers (right: 2.4 kg/cm2 [IQR 2.2 – 3.2, n = 15]; left: 2.5 kg/cm2 [2.3 – 3.2, n = 16]; P < 0.001 for both sides). Limitations: Only the SIJ on one side of was measured in patients with SIJ pain, where both sides would be desirable. Conclusions: Pressure pain algometry appears to be a reliable method to establish differences in PPTs between healthy volunteers and patients with SIJ pain. The diagnostic accuracy of this test should be investigated further. Key words: Sacroiliac joint pain, pain pressure threshold, pressure algometry

ABSTRACT The universal goniometer (UG) is the most frequently used tool for measuring range of motion (ROM), with demonstrated reliability. Computerized photogrammetry (CP) is widely used for postural assessment, but its role in the measurement of ROM of hip flexion and abduction has not yet been fully explored. This study aimed to test inter- and intra-rater reliability for measuring ROM of hip flexion and abduction using UG and CP, as well as the reliability between the instruments. Our sample consisted of 40 healthy volunteers (aged from 18 to 28 years). Measurements of ROM were conducted by two independent raters, 15 minutes apart, using UG and CP to assess inter-rater reliability. The procedures were repeated one week later by the first rater (intra-rater reliability). Using UG, inter-rater reliability was excellent for flexion and abduction (ICC=0.92 and 0.91, respectively); using CP, it was rated as very good (ICC=0.77 and 0.80, respectively). Intra-rater reliability using UG was excellent for flexion and abduction (ICC=0.95 and 0.92), and very good using CP (ICC= 0.81 and 0.89). The correlation between the instruments was excellent for flexion and very good for abduction (r=0.92 and r=0.82). Future investigations should seek a more diversified sample and symptomatic patients. Inter- and intra-rater reliability is high when measuring range of motion of hip flexion and abduction using both UG and CP, and the correlation between instruments is excellent for flexion and very good for abduction, meaning that both are valid.

Abstract. The Structured Interview for Hoarding Disorder (SIHD) is a semi-structured interview designed to assist clinicians in diagnosing a hoarding disorder (HD). This study aimed to validate the Italian version of the SIHD. For this purpose, its inter-rater reliability has been analyzed as well as its ability to differentiate HD from other disorders often comorbid. The sample was composed of 74 inpatients who had been diagnosed within their clinical environment: 9 with HD, 11 with obsessive-compulsive disorder (OCD) and HD, 22 with OCD, 19 with major depressive disorder (MDD), and 13 with schizophrenia spectrum disorders (SSD). The results obtained indicated “substantial” or “perfect” inter-rater reliability for all the core HD criteria, HD diagnosis, and specifiers. The SIHD differentiated between subjects suffering from and not suffering from a HD. Finally, the results indicated “good” convergent validity and high scores were shown in terms of both sensitivity and specificity for HD diagnosis. Altogether, the SIHD represents a useful instrument for evaluating the presence of HD and is a helpful tool for the clinician during the diagnostic process.
