TL;DR: In people with shoulder pain and functional loss, the intrarater reliability and error over 1 to 3 days were established using an HHD for measurement of isometric force for the assessment of scapular muscle performance.
Abstract: Background and Purpose. Scapular muscle performance evaluated with a handheld dynamometer (HHD) has been investigated only in people without shoulder dysfunction for test-retest reliability of data obtained with a single scapular muscle test. The purpose of this study was to assess the reliability, error, and validity of data obtained with an HHD for 4 scapular muscle tests in subjects with shoulder pain and functional loss. Subjects and Methods. Subjects (N=40) with shoulder pain and functional loss were tested by measuring the kilograms applied with an HHD during 3 trials for muscle tests for the lower trapezius, upper trapezius, middle trapezius, and serratus anterior muscles. Concurrently, surface electromyography (sEMG) data were collected for the 4 muscles. The same procedures were performed 24 to 72 hours after the initial testing by the same tester. Muscle tests were performed 3 times, and the results were averaged for data analysis. Results. Intraclass correlation coefficients for intratester reliability of measurements of isometric force obtained using an HHD ranged from .89 to .96. The standard error of the measure (90% confidence interval [CI]) ranged from 1.3 to 2.7 kg; the minimal detectable change (90% CI) ranged from 1.8 to 3.6 kg. Construct validity assessment, done by comparing the amounts of isometric muscle activity (sEMG) for each muscle across the 4 muscle tests, revealed that the muscle activity of the upper trapezius and lower trapezius muscles was highest during their respective tests. Conversely, the isometric muscle activity of the middle trapezius and serratus anterior muscles was not highest during their respective tests. Discussion and Conclusion. In people with shoulder pain and functional loss, the intrarater reliability and error over 1 to 3 days were established using an HHD for measurement of isometric force for the assessment of scapular muscle performance. Error values can be used to make decisions regarding individual patients. Construct validity was established for the lower and upper trapezius muscle tests; therefore, these tests are advocated for use. However, construct validity was not demonstrated for the serratus anterior and middle trapezius muscle tests as performed in this study. Further investigation of these muscle tests is warranted.

TL;DR: The Brazilian Portuguese version of the Fugl-Meyer Assessment Scale did not show any conflicts of interpretation, thereby allowing this version to be used as instrument for clinical evaluation and research in Brazil.
Abstract: Reliability Study on the Application of the Fugl-Meyer Scale in Brazil Objective: The aim of this study was to produce a Brazilian version of the original Fugl-Meyer Assessment Scale and to verify the intrarater and interrater reliability in chronic post-stroke patients. Method: Fifty hemiparetic patients participated in this study. The Fugl-Meyer assessment was applied to them twice (intrarater reliability) by three physiotherapists (interrater reliability), from three rehabilitation centers. Results: The results showed that the whole Fugl-Meyer scale demonstrated high interrater and intrarater reliability (intraclass correlation coefficient = 0.99 and 0.98, respectively), and high reliability for each subscale (intraclass interrater = 0.99 to 0.94; intraclass intrarater = 0.98 to 0.87). Conclusion: It was concluded that the Brazilian Portuguese version of the Fugl-Meyer Assessment Scale did not show any conflicts of interpretation. High intrarater and interrater reliability rates were obtained, thereby allowing this version to be used as instrument for clinical evaluation and research in Brazil.

TL;DR: In this article, the inter-and intra-observer reliability of movement control dysfunction tests of the lumbar spine was evaluated in 27 patients with non specific low back pain and 13 patients with other diagnoses but without back pain.
Abstract: Background: Movement control dysfunction [MCD] reduces active control of movements. Patients with MCD might form an important subgroup among patients with non specific low back pain. The diagnosis is based on the observation of active movements. Although widely used clinically, only a few studies have been performed to determine the test reliability. The aim of this study was to determine the inter- and intra-observer reliability of movement control dysfunction tests of the lumbar spine. Methods: We videoed patients performing a standardized test battery consisting of 10 active movement tests for motor control in 27 patients with non specific low back pain and 13 patients with other diagnoses but without back pain. Four physiotherapists independently rated test performances as correct or incorrect per observation, blinded to all other patient information and to each other. The study was conducted in a private physiotherapy outpatient practice in Reinach, Switzerland. Kappa coefficients, percentage agreements and confidence intervals for inter- and intra-rater results were calculated. Results: The kappa values for inter-tester reliability ranged between 0.24 – 0.71. Six tests out of ten showed a substantial reliability [k > 0.6]. Intra-tester reliability was between 0.51 – 0.96, all tests but one showed substantial reliability [k > 0.6]. Conclusion: Physiotherapists were able to reliably rate most of the tests in this series of motor control tasks as being performed correctly or not, by viewing films of patients with and without back pain performing the task.
