Accurate recording of spinal posture with simple and accessible measurement devices in clinical practice may lead to spinal loading optimization in occupations related to prolonged sitting and standing postures. Therefore, the purpose of this study was to establish the level of reliability of sagittal lumbosacral posture in quiet standing and the validity of the method in differentiating between male and female subjects, establishing in parallel a normative database. 183 participants (83 males and 100 females), with no current low back or pelvic pain, were assessed using the “iHandy Level” smartphone application. Intrarater reliability (3 same-day sequential measurements) was high for both the lumbar curve (ICC2,1: 0.96, SEM: 2.13°, andMDC95%: 5.9°) and the sacral slope (ICC2,1: 0.97, SEM: 1.61°, andMDC95%: 4.46°) sagittal alignment. Data analysis for each gender separately confirmed equally high reliability for both male and female participants. Correlation between lumbar curve and sacral slope was high (Pearson’sr=0.86,p<0.001). Between-gender comparisons confirmed the validity of the method to differentiate between male and female lumbar curve and sacral slope angles, with females generally demonstrating greater lumbosacral values (p<0.001). The “iHandy Level” application is a reliable and valid tool in the measurement of lumbosacral quiet standing spinal posture in the sagittal plane.

Abstract Introduction: In physiotherapeutic diagnostic processes, various tools and methods may be used. However, price and availability may limit their daily use in clinical practice. Therefore, the suggestion that smartphones with specific applications may be useful as diagnostic tools can be found in the literature. However, before using them in clinical practice, it is important to verify their reliability. The aim of the study was to evaluate the consistency of measurements of the curvatures in the sagittal plane performed with the Saunders digital inclinometer and a smartphone application. Materials and methods: The study included 40 subjects aged 22-39 years (23.0 ± 3.7). All subjects had sagittal spinal curvatures (sacral slope - SS, lumbar lordosis - L, thoracic kyphosis - K, upper thoracic kyphosis - K1, lower thoracic kyphosis - K2) measured in both standing and sitting positions with the Saunders digital inclinometer and a smartphone application. Results: In measurements performed with the use of the Saunders inclinometer and the smartphone, no significant differences were found between the size of the curvatures of the spine in a standing position (SS 19° ±8.2 vs. 17° ±8.4 p=0.3; L 32° ±11.1 vs. 29° ±10.3 p=0.2; K 43° ±8.4 vs. 41° ±8.1 p=0.2; K1 31° ±7.2 vs. 29.0° ±7.3; K2 11o ±7.4 vs. 11.0° ±6.7) and a sitting position (SS 3.75° ±8.9° p=0.8; L 5.8° ±9.06 vs. 5.2° ±8.5 p=0.75; K 40.0° ±8.1 vs. 36.7° ±7.9 p=0.6; K1 25.8° ±7.1 vs. 24.9° ±7.1; K2 14.5° ±9.9 vs. 11.5° ±9.4). Conclusions: The examination of spinal curvatures in the sagittal plane using Saunders digital inclinometer and a smartphone application allows researchers to obtain reliable results. Therefore, smartphones can be used for an objective evaluation of the musculoskeletal system in daily clinical practice.

Spinal Imbalance

In the anatomy of a normal spine, due to the curvatures in various regions, the C7 plumb line (C7PL) passes through the sacrum so that the head is centered over the pelvic-ball and socket hip and ankle joints. A failure to recognize malalignment in the sagittal plane can affect the patient's activity as well as social interaction due to deficient forward gaze. The sagittal balance configuration leads to the body undertaking the least muscular activities as possible necessary to maintain spinal balance. Global sagittal imbalance is energy consuming and often results in painful compensatory mechanisms that in turn negatively influence the patient's quality of life, self-image, and social interaction due to inability to maintain a horizontal gaze. Deformity, scoliosis, kyphosis, trauma, and/or surgery are some ways that this optimal configuration can be disturbed, thus requiring higher muscular activity to maintain posture and balance. Several parameters such as the thoracic kyphosis (TK), lumbar lordosis (LL), pelvic incidence (PI), sacral slope (SS), and hip and leg positions influence the sagittal balance and thus the optimal configuration of spinal alignment. This review examines the clinical and biomechanical aspects of spinal imbalance, and the biomechanics of spinal balance as dictated by deformities—ankylosing spondylitis (AS), scoliosis and kyphosis; surgical corrections—pedicle subtraction osteotomies (PSO), long segment stabilizations, and consequent postural complications like proximal and distal junctional kyphosis. The study of the biomechanics involved in spinal imbalance is relatively new and thus the literature is rather sparse. This review suggests several potential research topics in the area of spinal biomechanics.

Abstract Elicited imitation (EI), a short-cut measure of global proficiency in second language (L2) research, requires participants to listen to sentences and repeat them as closely as possible. To support instrument sharing and assessment of L2 proficiency for longitudinal and crosslinguistic research, we created a parallel form of an EI task (EIT) for L2 English originally developed by the third author and colleagues and investigated the reliability and validity of the original and new forms. Eighty-two participants completed the two EITs, an oral narrative task, and a self-diagnostic survey. Both forms exhibited high reliability and good alignment with external criterion measures. Both distinguished well among four proficiency levels in the sample. Further, participants’ perception of EI difficulty aligned well with their EI scores. We suggest some improvements to boost forms equivalence and discuss new insights about the nature of EI as reconstructive, integrative, modality independent, and with indirect links to communicative abilities. Our study seeks to make this English EIT instrument widely useful to the L2 research community.

This article develops a familiness scale measuring the family influence on the business via decision premises that express familiness. In three studies, we examine familiness with qualitative and quantitative approaches based on new systems theory. Narrative interviews are employed to generate items. Exploratory and confirmatory factor analyses led to a multidimensional scale (Family Influence Familiness Scale [FIFS]) comprising six dimensions: (1) ownership, management, and control; (2) proficiency level of active family members; (3) sharing of information between active family members; (4) transgenerational orientation; (5) family–employee bond; and (6) family business identity. Results indicate high reliability and validity levels.

Objective: The purpose of this study was to assess psychometric properties of the six-item Headache Impact Text (HIT-6™) across episodic and chronic migraine. Methods: Using a migraine screener and number of headache days per month (HDPM), participants from the National Survey of Headache Impact (NSHI) study and the HIT-6 validation study (HIT6-V) were selected for this study. Eligible participants were categorized into three groups: chronic migraine (CM: ≥ 15 HDPM); episodic migraine (EM: < 15 HDPM); non-migraine headaches. Reliability and validity of the HIT-6 were evaluated. Results: A total of 2,049 survey participants met the inclusion/exclusion criteria for this study. Participants were identified as 6.4% CM; 42.1% EM; 51.5% non-migraine, with respective mean HIT-6 scores: 62.5 ± 7.8; 60.2 ± 6.8; and 49.1 ± 8.7. High reliability was demonstrated with internal consistency (time1/time2) of 0.83/0.87 in NSHI, and 0.82/0.92 in HIT6-V. Intra-class correlation for test-retest reliability was very good at 0.77. HIT-6 scores correlated significantly ( p < .0001) with total Migraine Disability Assessment Scale scores ( r = 0.56), headache pain severity ( r = 0.46), and HDPM ( r = 0.29). Discriminant validity analysis showed significantly different HIT-6 scores ( F = 488.02, p < .0001) across the groups. Conclusion: Results from these analyses confirm that the HIT-6 is a reliable and valid tool for discriminating headache impact across episodic and chronic migraine.

Beck Hopelessness Scale

ABSTRACTBackground:Older adults represent the segment of population most exposed to the risk of suicide nearly everywhere in the world. Previous studies showed that hopelessness was an important risk factor for suicide.Aims:This study aimed to evaluate the reliability and validity of the four-item Beck Hopelessness Scale (BHS-4) in psychological autopsy study among Chinese rural elderly.Method:Two-stage stratified cluster sampling method was used to select research sites. Using case-control psychological autopsy study, face-to-face interviews were conducted to collected information.Results:A total of 242 elderly suicide deaths and 242 matched living comparisons were investigated, including 135 males and 107 females for each group. Intraclass Correlation Coefficients (ICC) of the controls were 0.682-0.713. The median score of BHS-4 among suicides was significantly higher than that among controls. The corrected correlation coefficient between items and total score were 0.184-0.723. Cronbach’s Alphas coefficient was 0.834. Only one common factor was precipitated by exploratory factor analysis and the cumulative variance contribution rates were 59.558% for suicides and 52.722% for living controls. The correlation coefficient between hopelessness and depression were 0.481 among suicide death and 0.617 among living controls.Conclusion:The information provided by the informants through psychological autopsy method had high reliability to reflect the actual situation of suicides and controls. BHS-4 has good reliability and validity among Chinese rural elderly suicides. It is suitable for psychological autopsy study among Chinese rural elderly.

Experiences In Close Relationships

Currently, there is no instrument to quickly measure adult attachment in the Chinese cultural context. In this study the Experiences in Close Relationships Scale–Short Form (ECR-S) was translated and tested in terms of reliability and validity with Chinese college students. All items of the Chinese-version ECR-S showed high discriminability and the scale had a two-dimensional structure in both exploratory and confirmatory factor analyses. The internal consistency coefficients of the two subscales of the ECR-S showed excellent reliability, and scores were modestly to highly correlated with the criteria of state adult attachment, self-esteem, anxiety, pressure, depression, and satisfaction with intimate (romantic) relationships. It can be concluded that the Chinese version of the ECR-S has high reliability and validity; thus, it meets the requirements for psychometric tools and can be used to assess Chinese adults' attachment.

This study aimed to compare static posture of male and female riders on a riding simulator. Ten female and five male riders underwent a 5 min standardised exercise programme on the simulator, they were then videoed for 10 s from each the left, right, and rear views whilst stationary on the simulator. Two-dimensional kinematic analysis of the videos showed that male riders had a more neutrally positioned pelvis in the sagittal plane (median left: 6.47°, right: 5.24°) with females demonstrating a posterior pelvic tilt (L: 14.04°, R: 13.55°). Females showed significantly greater pelvic obliquity (median female: 1.99°, male: 0.73°), trunk lean (F: 1.60°, M: 0.43°), and shoulder tilt (F: 1.79°, M: 0.57°) in the frontal plane, demonstrating an overall greater postural asymmetry. Previous studies of elite riders have shown a more anteriorly rotated pelvis to be more desirable. Symmetry of riding position is favourable as it allows movements to be performed with ease and ensures even force distribution through the saddle to the horse. Male riders may therefore have a biomechanical advantage over females when it comes to maintaining a desirable riding position. This research should now be extended to study riders on the horse in motion.
