Inter-observer and intra-observer reliability in the radiographic measurements of paediatric forefoot alignment

BackgroundFoot bones in children have more rounded shapes in radiograms than adults. Thus, the goal of this work was assessing inter- and intra-observer reliability in paediatric forefoot angle measurements.Material and methodsSix forefoot angles in 34 AP standing paediatric foot radiographs were measured by 5 researchers. A classic statistical analysis with use of IBM SPSS Statistics 25 was performed and a new method with two-way analysis of variance was applied.ResultsResults of statistical analysis revealed the properties of a subjective assessment related to specific angles. Kilmartin’s angle, calcaneus-fifth metatarsal angle and first ray angle are the most reliable; metatarsus adductus angle should be used with great caution in pediatric population. Engel’s angle is the most difficult for measuring and measurement error is the highest.ConclusionThe power of paediatric forefoot measurements is various. Several angles are reliable, while Engle’s angle is the most doubtful.

Abstract

Objective

To examine the psychometric properties of the Community Integration Questionnaire (CIQ) in large samples of individuals with spinal cord injury (SCI).

Design

Longitudinal 12-month survey study.

Setting

Nation-wide, community dwelling.

Participants

Adults with SCI: 627 at Time 1, 494 at Time 2.

Interventions

Not applicable.

Outcome measures

The CIQ is a 15-item measure developed to measure three domains of community integration in individuals with traumatic brain injury: home integration, social integration, and productive activity. SCI consumer input suggested the need for two additional items assessing socializing at home and internet/email activity.

Results

Exploratory factor analyses at Time 1 indicated three factors. Time 2 confirmatory factor analysis did not show a good fit of the 3-factor model. CIQ scores were normally distributed and only the Productive subscale demonstrated problems with high (25%) ceiling effects. Internal reliability was acceptable for the Total and Home scales, but low for the Social and Productive activity scales. Validity of the CIQ is suggested by significant differences by sex, age, and wheelchair use.

Conclusions

The factor structure of the CIQ was not stable over time. The CIQ may be most useful for assessing home integration, as this is the subscale with the most scale stability and internal reliability. The CIQ may be improved for use in SCI by including items that reflect higher levels of productive functioning, integration across the life span, and home- and internet-based social functioning.     

Linguistic validation and reliability properties are weak investigated of most dementia-specific quality of life measurements—a systematic review

ObjectiveFor people with dementia, the concept of quality of life (Qol) reflects the disease's impact on the whole person. Thus, Qol is an increasingly used outcome measure in dementia research. This systematic review was performed to identify available dementia-specific Qol measurements and to assess the quality of linguistic validations and reliability studies of these measurements (PROSPERO 2013: CRD42014008725).Study Design and SettingThe MEDLINE, CINAHL, EMBASE, PsycINFO, and Cochrane Methodology Register databases were systematically searched without any date restrictions. Forward and backward citation tracking were performed on the basis of selected articles.ResultsA total of 70 articles addressing 19 dementia-specific Qol measurements were identified; nine measurements were adapted to nonorigin countries. The quality of the linguistic validations varied from insufficient to good. Internal consistency was the most frequently tested reliability property. Most of the reliability studies lacked internal validity.ConclusionQol measurements for dementia are insufficiently linguistic validated and not well tested for reliability. None of the identified measurements can be recommended without further research. The application of international guidelines and quality criteria is strongly recommended for the performance of linguistic validations and reliability studies of dementia-specific Qol measurements.     

Assessing the Reliability of Ultrasound Imaging to Examine Peripheral Nerve Excursion: A Systematic Literature Review

Ultrasound imaging (USI) is gaining popularity as a tool for assessing nerve excursion and is becoming an important tool for the assessment and management of entrapment neuropathies. This systematic review aimed to identify current methods and report on the reliability of using USI to examine nerve excursion and identify the level of evidence supporting the reliability of this technique. A systematic search of five electronic databases identified studies assessing the reliability of using USI to examine nerve excursion. Two independent reviewers critically appraised and assessed the methodological quality of the identified articles. Eighteen studies met the eligibility criteria. The majority of studies were of “moderate” or “high” methodological quality. The overall analysis indicated a “strong” level of evidence of moderate to high reliability of using USI to assess nerve excursion. Further reliability studies with consistency of reporting are required to further strengthen the level of evidence.     

The Sensational Hand: Clinical Assessment after Nerve Repair

Following the transection and repair of major nerve trunks in the forearm, the functional outcome is influenced by mechanisms in the peripheral, as well as in the central nervous system. In the present thesis the interest is focused on assessment of the outcome after nerve repair, central nervous factors influencing the outcome, and sense substitution to compensate for sensory loss. A new model instrument for routine documentation of the outcome after repair of a peripheral nerve is identified. The model includes assessments reflecting sensory, motor and pain/discomfort domains. Investigations of frequently used assessment instruments led to the construction and evaluation of a new test instrument for assessment of discriminative sensibility (tactile gnosis) to fit in the model. The summarised outcome, calculated from the model instrument and with a numerical scoring system, conforms well with the patient's opinion on the influence on activities of daily living resulting from the nerve injury, and demonstrates good reliability and validity. A reference interval for the outcome is presented, with the estimated 95% predicted values for the outcome up to five years after the nerve repair. Brain plasticity is a factor sensibility - tactile gnosis - in the adaptive process after a nerve injury, when the mind has to interpret new signal patterns, when objects are touched. For better understanding of the sensory outcome after nerve repair, central nervous factors were examined. Specific cognitive capacities, such as verbal learning and visuo-spatial logic capacity could be identified as being of importance for recovery of tactile gnosis. For patients with temporary or permanent sensory loss, a new principle for artificial sensibility based on sense substitution is presented. The hearing sense substitutes the sense of touch. The resemblance in perceptual experience between sound and touch is bridged by the stereophonic friction sound generated by touching objects, which is then amplified and transmitted to earphones. The delicate capacity of the sense of hearing to discriminate between the complex pattern of frequencies makes it reasonable to assume that hearing is able to take over functions normally devoted to touch. This is demonstrated in the thesis.     

Adolescent Stress Questionnaire: Reliability and validity of the Greek version and its description in a sample of high school (lyceum) students

Adolescence is a crucial phase of human life characterized by enhanced exposure and vulnerability to various stressful stimuli. The Adolescent Stress Questionnaire (ASQ) is a useful measure to evaluate possible sources of stressors affecting the adolescent equilibrium. The present study examines the scientific properties of the Greek version of ASQ to measure perceived stress among 250 Greek adolescents. The confirmatory factor analysis (CFA) results showed a good fit of the original structure of ASQ to the observed data in the Greek sample. A good internal reliability was also confirmed by high Cronbach's alpha values. In line with previous research, girls reported more stress than boys. Overall, the Greek ASQ is a valid and reliable instrument for evaluating adolescent stress.
