TL;DR: HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not, for teaching and research institutions in France or abroad.
Abstract: HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d’enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

TL;DR: Reliability ratios values typically were highest (greater than 90%) for aspiration, especially with solid food, and lowest for the functional components, and it was concluded that inter- and intrarater reliability in VFSS are adequate for evaluating oral stage, laryngeal penetration, and aspiration and pharyngeAL retention, but questionable for functional components.
Abstract: The objective of this study was to determine the inter- and intrarater reliability in evaluating videofluoroscopic swallowing studies (VFSS). Participants included 4 physicians (3 physiatrists and 1 internist) and 5 speech-language pathologists with at least 5 years experience in evaluating VFSS. The main outcomes of the study were reliability ratios of positive and negative tests in inter- and intrarater evaluations. Raters independently rated each of 20 VFSS on two separate occasions. Traits evaluated included oral stage impairment, aspiration, pharyngeal retention, and several functional components: timing of swallow onset, adequacy of velopharyngeal apposition, laryngeal elevation, epiglottic tilt, pharyngeal contraction, and pharyngoesophageal (PE) segment opening. Reliability varied widely depending on food type and the trait under evaluation. Inter- and intrarater reliability ratios did not differ widely. Reliability ratios values typically were highest (greater than 90%) for aspiration, especially with solid food, and lowest for the functional components. It was concluded that inter- and intrarater reliability in VFSS are adequate for evaluating oral stage, laryngeal penetration, and aspiration and pharyngeal retention, but questionable for functional components.

TL;DR: Intrarater reliability of the visual assessment of cervical and lumbar lordosis was statistically fair, whereas interrater reliability was poor.
Abstract: Study design Blinded test-retest design. Objective To measure the intrarater and interrater reliability of the visual assessment of cervical and lumbar lordosis. Summary of background data Cervical and lumbar lordoses are frequently evaluated using visual assessment, but little attempt has previously been made to measure the reliability of visual assessment. Methods Twenty-eight chiropractors, physical therapists, physiatrists, rheumatologists, and orthopedic surgeons were recruited to evaluate the posture of photographed subjects (with and without back pain). Each clinician rated the lordosis of the cervical and lumbar spines as normal, increased, or decreased. Kappa coefficients (kappa) were calculated to determine intrarater and interrater reliability. Results Twenty-eight clinicians evaluated photographs of 36 individuals (17 with back pain, 19 without). Mean intrarater reliability was kappa = 0.50 (95% confidence interval 0.02-0.98) and mean interrater reliability was kappa = 0.16 (95% confidence interval 0.00-0.48). No statistically significant difference existed among the five groups of clinicians or between the evaluation of the subjects with and without back pain. Conclusion Intrarater reliability of the visual assessment of cervical and lumbar lordosis was statistically fair, whereas interrater reliability was poor.

TL;DR: The responsiveness of ankle joint range-of-motion measurements is uncertain and requires further studies using patient populations, and how the characteristics of the study population or clinician affect reliability is investigated.
Abstract: This article reviews the existing range-of-motion measurement literature related to ankle dorsiflexion and plantarflexion to determine whether the reliability of ankle range-of-motion measurements can be defined, how the characteristics of the study population or clinician affect reliability, and the level of responsiveness for these measures. A MEDLINE search was performed through February 2004, and 11 articles met the inclusion criteria established for this review. Ample evidence was found for intrarater reliability for ankle dorsiflexion and plantarflexion range of motion. Although some evidence for interrater reliability of dorsiflexion was found, little evidence for interrater reliability of plantarflexion range of motion was uncovered. On the basis of the current literature, the responsiveness of ankle joint range-of-motion measurements is uncertain and requires further studies using patient populations.
