The objectives of this study were to evaluate the reliability of wearable inertial motion unit (IMU) sensors in measuring spinal range of motion under supervised and unsupervised conditions in both laboratory and ambulatory settings. A secondary aim of the study was to evaluate the reliability of composite IMU metrology scores (IMU-ASMI (Amb)). Forty people with axSpA participated in this clinical measurement study. Participant spinal mobility was assessed by conventional metrology (Bath Ankylosing Spondylitis Metrology Index, linear version—BASMILin) and by a wireless IMU sensor-based system which measured lumbar flexion-extension, lateral flexion and rotation. Each sensor-based movement test was converted to a normalized index and used to calculate IMU-ASMI (Amb) scores. Test-retest reliability was evaluated using intra-class correlation coefficients (ICC). There was good to excellent agreement for all spinal range of movements (ICC > 0.85) and IMU-ASMI (Amb) scores (ICC > 0.87) across all conditions. Correlations between IMU-ASMI (Amb) scores and conventional metrology were strong (Pearson correlation ≥ 0.85). An IMU sensor-based system is a reliable way of measuring spinal lumbar mobility in axSpA under supervised and unsupervised conditions. While not a replacement for established clinical measures, composite IMU-ASMI (Amb) scores may be reliably used as a proxy measure of spinal mobility.

Abstract Objective The Routine Opioid Outcome Monitoring (ROOM) tool measures outcomes with opioids using an established framework which includes domains such as pain, mood, opioid use disorder, alcohol use, and constipation. This study aims to validate and establish the test-retest reliability of the computer-administered ROOM tool. Design and Setting Cross-sectional analysis of an online sample. Subjects Participants comprised those with chronic noncancer pain who regularly used prescription opioids. Methods Participants self-completed the online ROOM tool along with other validated measures (validation questionnaire), and those who were agreeable also completed the online test-retest questionnaire approximately two weeks later. Subcomponents of the ROOM tool (i.e., pain, mood, alcohol use, opioid use disorder, and constipation) were validated against longer measures of the same construct using Pearson correlation coefficients. Intraclass correlation coefficients were used to assess the stability of the ROOM tool over time. Results A total of 324 participants completed the validation questionnaire, of whom 260 also completed the test-retest questionnaire. The opioid use disorder domain showed good sensitivity (73.6) and specificity (75.8) against the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, any opioid use disorder. All ROOM components showed moderate correlation (r = 0.55–0.73) with their longer counterparts. Test-retest reliability was fair (0.58–0.75), indicating that responses were relatively stable over time. Reliability did vary, however, based on the components being measured and how certain tools were scored. Conclusion The computer-administered ROOM tool is a valid approach for brief monitoring of outcomes with prescribed opioids in primary care settings and appears to be acceptable to people who are using prescribed opioids for chronic pain.

Abstract Context: Inadequate hip active range of motion (AROM) may stifle the energy flow through the kinematic chain and decrease pitching performance while increasing the risk for pitcher injury. Objective: To examine the relationship of hip AROM and pitching biomechanics during a fastball pitch in adolescent baseball pitchers. Design: Cross-Sectional study. Setting: Biomechanics laboratory. Participants: A voluntary sample of 21 adolescent baseball pitchers (16.1 ± 0.8 yrs.; 183.9 ± 5.2 cm; 77.9 ± 8.3 kg). Main Outcome Measure (s): Bilateral hip internal rotation (IR), external rotation (ER), flexion, extension, and abduction AROM were measured. Three-dimensional biomechanics were assessed as participants threw from an indoor pitching mound to a strike zone net at regulation distance. Pearson correlation coefficients were used to determine correlations between hip AROM and biomechanical metrics. Results: Statistically significant negative correlations were found at foot contact between back hip ER AROM and back hip abduction angle (p=0.030, r=−0.474), back hip ER AROM and torso rotation angle (p=0.032, r=−0.468),and back hip abduction AROM and lead hip abduction angle (p=0.037, r=−0.458). Back hip extension AROM was positively correlated with increased stride length (p=0.043, r=0.446). Lead hip abduction AROM was also positively correlated with normalized elbow varus torque (p=0.034, r=0.464). Conclusions: There were several relationships between hip AROM and biomechanical variables during the pitching motion. The findings support the influence hip AROM can have on pitching biomechanics. Overall, greater movement at the hips allows for the kinematic chain to work at its maximal efficiency, increasing pitch velocity potential.

To objectively evaluate in-patient rehabilitation programmes in China, we developed a new rating scale: the Inpatient Psychiatric Rehabilitation Outcome Scale (IPROS). The scale has five subscales: performance in occupational therapy, daily activities, socialisation, personal hygiene, and level of interest in external events. Evaluators (physicians or nurses) observe patients for one week before coding items on a five-point scale. Comparison of four independent evaluators' results for 32 schizophrenic patients assessed on two separate occasions indicated that the inter-rater and test-retest reliability for the overall IPROS score and for the five subscale scores was excellent (all ICC values ≥0.973). Validity was evaluated by comparing IPROS results with those of five other independently assessed clinical measures for 101 chronic schizophrenic patients before and after a six-month rehabilitation programme; concurrent validity and longitudinal validity were satisfactory (correlation coefficients 0.37–0.81, all P values <0.01).

Parents of children with developmental disabilities, particularly Autism Spectrum disorder, are known to be at risk for high levels of psychological distress. The present study aimed to adapt the Quality of Life in Autism Questionnaire (QoLA, parent-version) in the context of Bangladeshi culture. The sample included 50 participants. Participants were selected from the Institute of Paediatric Neurology and Autism (IPNA, BSMMU) and some special schools of Dhaka city. World Health Organization’s (WHO, 2009) guidelines were followed in translating the QoLA and adaptation for use in Bangladesh. For the parent-report version of the QoLA, Cronbach’s coefficients were 0.880 and 0.725 for part A and part B subscale items, respectively. The Pearson correlation coefficients for the test-retest reliability were r =0.964 for part A of the scale and r = 0.954 for part B. These psychometric properties are comparable to those obtained in the initial QoLA validation study (Eapen et al. 2014). Results of this study demonstrate that the Bangla version of the QoLA (Parent version) provides a valid measure of quality of life and is suitable for use in Bangladesh.

The purpose of this study was to translate and culturally adapt the Carpal Tunnel Questionnaire to produce an equivalent Korean version. A total of 53 patients completed the Korean version of the Carpal Tunnel Questionnaire pre-operatively and 3 months after open carpal tunnel release. All 53 also completed the Korean version of the Disabilities of Arm, Shoulder, and Hand questionnaire pre-operatively and 3 months post-operatively. Reliability was measured by determining the test–retest reliability and internal consistency. Test–retest reliability was assessed using intraclass correlation coefficients and paired t-tests, and internal consistency using Cronbach’s alpha coefficients. Pearson correlation analysis was carried out on the Korean version of the Carpal Tunnel Questionnaire scores and the Korean version of the Disabilities of Arm, Shoulder, and Hand scores to assess construct validity. Responsiveness was evaluated using effect sizes and standardized response means. The reliability of the Korean version of the Carpal Tunnel Questionnaire was good. The scores in the Korean version of the Disabilities of Arm, Shoulder, and Hand strongly correlated with the scores in the Korean version of the Carpal Tunnel Questionnaire. Standardized response mean and effect size were both large for the Korean version of the Carpal Tunnel Questionnaire. The study shows that the Korean version of the Carpal Tunnel Questionnaire is a reliable, valid and responsive instrument for measuring outcomes in carpal tunnel syndrome.

Abstract Objective To evaluate the validity and reliability of inertial measurement unit (IMU) sensors in the assessment of spinal mobility in axial spondyloarthritis (axSpA). Methods A repeated measures study design involving 40 participants with axSpA was used. Pairs of IMU sensors were used to measure the maximum range of movement at the cervical (Cx) and lumbar (Lu) spine. A composite IMU score was defined by combining the IMU measures. Conventional metrology and physical function assessment were performed. Validation was assessed considering the agreement of IMU measures with conventional metrology and correlation with physical function. Reliability was assessed using intra-class correlation coefficients (ICCs). Results The composite IMU score correlated closely (r = 0.88) with the BASMI. Conventional Cx rotation and lateral flexion tests correlated closely with IMU equivalents (r = 0.85, 0.84). All IMU movement tests correlated strongly with BASFI, while this was true for only some of the BASMI tests. The reliability of both conventional and IMU tests (except for chest expansion) ranged from good to excellent. Test–retest ICCs for individual conventional tests varied between 0.57 and 0.91, in comparison to a range from 0.74 to 0.98 for each of the IMU tests. Each of the composite regional IMU scores had excellent test–retest reliability (ICCs=0.94–0.97), comparable to the reliability of the BASMI (ICC=0.96). Conclusion Cx and Lu spinal mobility measured using wearable IMU sensors is a valid and reliable assessment in multiple planes (including rotation), in patients with a wide range of axSpA severity.

Limitations in hand function are common among children with cerebral palsy (CP), with almost 50% presenting an arm–hand dysfunction. However, there is no standardized assessment tool available in Italian for evaluating bimanual performance for this population. Our objective in this study was to evaluate the psychometric properties of an Italian translation of the ABILHAND-Kids (ABILHAND-Kids-IT) among children with CP. We examined internal consistency using Cronbach’s Alpha and Omega coefficients, and we investigated test-retest reliability with intraclass correlation coefficients (ICC). We performed explorative factor analysis (EFA) to investigate structural validity. We calculated Pearson’s correlation coefficients between the ABILAND-Kids IT and the Manual Ability Classification System (MACS) to assess criterion validity; and, to demonstrate the score variability of the ABILHAND-Kids-IT, we used analyses of variance (ANOVAs) to compare the 181 children with CP in this sample with their levels on the MACS. We enrolled 181 children with CP in the study. EFA confirmed a uni-dimensional scale. We obtained internal consistency on both Cronbach’s Alpha and Omega coefficient of 0.98, and a one-week test-retest reliability analysis revealed an ICC with 95% of confidence interval of .992. The ANOVA revealed significant score variability ( p < 0.01) and the Pearson correlation coefficient comparing the ABILHAND-Kids-It score with the MACS was –0.929 ( p < 0.01). We conclude that the ABILHAND-Kids-IT is valid and reliable for use with Italian children with CP.

Background Balance assessment is necessary when evaluating athletes after a concussion. We investigated a mobile device application (app) for providing valid, reliable, and objective measures of static balance. Objectives The mobile device app would demonstrate similar test–retest reliability to force platform center of pressure (COP) sway variables and that SWAY scores and force platform COP sway variables would demonstrate good correlation coefficients. Methods Twenty-six healthy adults performed balance stances on a force platform while holding a mobile device equipped with SWAY (Sway Medical LLC) to measure postural sway based on acceleration changes detected by the mobile device's accelerometer. Participants completed four series of three 10-second stances (feet together, tandem, and single leg), twice with eyes open and twice with eyes closed. Test–retest reliability was assessed using intraclass correlation coefficients (ICC). Concurrent validity of SWAY scores and COP sway variables were determined with Pearson correlation coefficients. Results Reliability of SWAY scores was comparable to force platform results for the same test condition (ICC = 0.21–0.57). Validity showed moderate associations between SWAY scores and COP sway variables during tandem stance (r = –0.430 to –0.493). Lower SWAY scores, indicating instability, were associated with greater COP sway. Discussion The SWAY app is a valid and reliable tool when measuring balance of healthy individuals in tandem stance. Further study of clinical populations is needed prior to assessment use. Conclusion The SWAY app has potential for objective clinical and sideline evaluations of concussed athletes, although continued evaluation is needed.

Purpose This study reports the psychometric development of the Cantonese versions of the English Computerized Revised Token Test (CRTT) for persons with aphasia (PWAs) and healthy controls (HCs). Method The English CRTT was translated into standard Chinese for the Reading–Word Fade version (CRTT-R- WF -Cantonese) and into formal Cantonese for the Listening version (CRTT-L-Cantonese). Thirty-two adult native Cantonese PWAs and 42 HCs were tested on both versions of CRTT-Cantonese tests and on the Cantonese Aphasia Battery to measure the construct and concurrent validity of CRTT-Cantonese tests. The HCs were retested on both versions of the CRTT-Cantonese tests, whereas the PWAs were randomly assigned for retesting on either version to measure the test–retest reliability. Results A two-way, Group × Modality, repeated-measures analysis of variance revealed significantly lower scores for the PWA group than the HC group for both reading and listening. Other comparisons were not significant. A high and significant correlation was found between the CRTT-R- WF -Cantonese and the CRTT-L-Cantonese in PWAs, and 87% of the PWAs showed nonsignificantly different performance across the CRTT-Cantonese tests based on the Revised Standardized Difference Test. The CRTT-R- WF -Cantonese provided better aphasia diagnostic sensitivity (100%) and specificity (83.30%) values than the CRTT-L-Cantonese. Pearson correlation coefficients revealed significant moderate correlations between the Cantonese Aphasia Battery scores and the CRTT-Cantonese tests in PWAs, supporting adequate concurrent validity. Intraclass correlation coefficient showed high test–retest reliability (between .82 and .96, p < .001) for both CRTT-Cantonese tests for both groups. Conclusions Results support that the validly translated CRTT-R- WF -Cantonese and CRTT-L-Cantonese tests significantly differentiate the reading and listening comprehension of PWAs from HCs and provides acceptable concurrent validity and high test–retest reliability for both tests. Furthermore, favorable PWA versus HC sensitivity and specificity cutoff scores are presented for both CRTT-Cantonese listening and reading tests.

Forty-eight first- and second-grade children with /r/ or /s/ errors met with an articulation examiner once a week for three consecutive weeks. During each session, the investigator role-played social behaviors of a supportive examiner (S) or a non-supportive examiner (N) (Relationship Segment) and then administered a Vocal Imitation Task and an imitative Articulation Task (Testing Segment). Subjects were divided into four groups balanced by sex, error sound, grade, and therapy experience. The sequence of experimental conditions for each group was Group 1 (SSS); Group 2 (NNN); Group 3 (SNS); and Group 4 (NSN). Two questions were posed: Do supportive versus nonsupportive examiner social behaviors affect articulation performance? Do differences in examiner social behaviors affect children’s test-retest reliability? No main or interaction effects for the type of examiner behaviors were obtained on either dependent variable. Comparison of the Pearson correlation coefficients for each group indicated that Group 1 obtained the highest temporal reliability, 0.92, while Groups 2, 3, and 4 obtained average coefficients of 0.67, 0.76, and 0.62, respectively. Clinical and theoretical implications of these data point to the value of using intensive designs for further study of interpersonal variables in the clinical process.
