Determining the Interrater Reliability of the SOFMER Activity Score (version 2) for Individuals in Rehabilitation Centers.

OBJECTIVE: To assess the interrater reliability of the SOFMER Activity Score (SAS) (version 2 [v2], an 8-item [4 motor and 4 cognitive] and 5-level scale) and improve its scoring system before conducting further validation steps. DESIGN: Cross-sectional, prospective, observational, noninterventional, and multicentric study. SETTING: The study was conducted between November 2018 and September 2019 in 4 French rehabilitation centers (2 public university hospitals for adults and 2 private not-for-profit rehabilitation centers for children). PARTICIPANTS: The study included 101 participants (N=101; mean age, 44.5±25.4 years; 28.7% younger than 18 and 18.8% older than 65 years). The female/male sex ratio was 0.6. The causes for admission to the center were mainly neurologic (65%) or orthopedic (24%). INTERVENTIONS: None. MAIN OUTCOME MEASURES: Activity limitation was rated with the SAS the same day by 2 independent multidisciplinary teams. The interrater reliabilities of the score items were assessed using weighted kappa coefficients. RESULTS: All weighted kappa coefficients ranged between 0.83 and 0.92, indicating "good" to "excellent" interrater reliability. Interteam score disagreements occurred in 227 of 808 scores (28%). The reason for most disagreements was unnoticed human or material aid during the observation period. CONCLUSIONS: The results demonstrate the high interrater reliability of the SASv2 and allow carrying out further validation steps after minor changes to item scoring instructions and clearer definitions of some items that help improving scoring standardization. The SASv2 may then become a consistent measure of activity level for clinical research or burden of care investigations.

Additional validation study and French cross-cultural adaptation of the Pediatric Stroke Outcome Measure-Summary of Impressions (PSOM-SOI).

BACKGROUND: The Pediatric Stroke Outcome Measure-Summary of Impressions (PSOM-SOI) measures neurological function across right and left sensorimotor domains (Item A), language production (Item B), language comprehension (Item C), and cognition/behaviour (Item D). OBJECTIVE: This study was a cross-cultural adaptation into French of the PSOM-SOI and an assessment of its reliability and limitations of use. MATERIAL AND METHODS: The translation and adaptation of the PSOM-SOI was followed by the assessment of its reliability in a cohort of 69 children with diagnosed acute neonatal arterial ischemic stroke. Three independent raters retrospectively scored the PSOM-SOI based on data from in-person neurological examination and results of standardized tests performed at age 7 in the cohort database. Comparison 1 (C1) involved a less experienced rater and an experienced rater and comparison 2 (C2) involved 2 experienced raters. Inter-rater reliability (IRR) was measured with Kappa coefficients. RESULTS: The cross-cultural adaptation was easily performed, and no rater had difficulties using the French PSOM-SOI. The IRR was better in C1 than C2. For Item A, the agreement in C1 (κ=0.47) and C2 (κ=0.44) was moderate. The C1 agreement was substantial for Items B (κ=0.71) and C (κ=0.70); the C2 agreement was fair for Item B (κ=0.23) and slight for Item C (κ=0.16). For Item D, the agreement was moderate in C1 (κ=0.52) and fair in C2 (κ=0.35). In all but one comparison, agreement or minor disagreement (≤0.5 points) was obtained for more than 90% of the item scores. Regarding the total score, agreement for normal function (≤0.5) versus abnormal function (>0.5) was achieved for 90% in C1 and 67% in C2. CONCLUSION: The IRR of the French PSOM-SOI gave variable results depending on the item and rater's experience, but the extent of disagreements was minor for individual items and total score. Additional prospective validation studies using the French PSOM-Short Neurological Exam to score the PSOM-SOI are needed. A dichotomised total score (cut-off≤0.5) could be used to define normal function versus poor outcome.

[French adaptation of motor function scales for patients with spinal muscular atrophy]. / SMA: Des échelles d'évaluation motrice pour le public francophone.

TITLE: SMA: Des échelles d'évaluation motrice pour le public francophone. ABSTRACT: À l'heure des nouvelles thérapeutiques chez les personnes présentant une amyotrophie spinale antérieure ou spinal muscular atrophy (SMA), la mesure régulière, précise et fiable des capacités motrices est devenue indispensable. Différents outils ont été développés dans la littérature et peuvent être utilisés pour cela. Le choix d'une échelle/ d'un outil se fait en fonction du type de SMA, de l'âge de la personne et des éléments spécifiques de la motricité que l'on souhaite évaluer. En France, l'échelle MFM est utilisée en pratique clinique dans de nombreux centres de référence de Maladies Neuromusculaires (MNM). Les autres échelles fréquemment utilisées au niveau international ne sont cependant pas disponibles en français rendant leur utilisation plus difficile en pratique clinique courante. Cet article présente le processus de traduction en français des échelles les plus fréquemment utilisées chez la personne avec SMA (CHOP INTEND, HFMSE, RULM, 6-minute walk test et HINE-2). Différentes étapes ont été respectées, notamment les étapes de traduction en français, traduction inversée en anglais, comparaison des versions anglaises, harmonisation et obtention de la version finale en français. Un programme de formation et sensibilisation des différents professionnels des consultations MNM des centres de référence français avec proposition d'ateliers en présence des membres du comité scientifique suivra l'étape de traduction afin de les faire connaître, expliciter leur utilisation et participer à la diffusion de ce travail.

Fixed-distance walk tests at comfortable and fast speed: Potential tools for the functional assessment of coronary patients?

OBJECTIVES: There is ambiguity concerning the walk tests available for functional assessment of coronary patients, particularly for the walking speed. This study explores the psychometric properties of two walking tests, based on fixed-distance tests, at comfortable and fast velocity, in stabilized patients at the end of a cardiac rehabilitation program. METHODS: At a three-day interval 58 coronary patients (mean age of 64.85±6.03 years, 50 men) performed three walk tests, the first two at a comfortable speed in a random order (6-minute walk test - 6MWT - and 400-metre comfortable walk test - 400mCWT) and the third at a brisk speed (200-metre fast walk test - 200mFWT). A modified Bruce treadmill test was associated at the end of the second phase. Monitored main parameters were: heart rate, walking velocity, VO2. RESULTS: Tolerance to the 3 tests was satisfactory. The reliability of the main parameters was good (intraclass correlation coefficient>0.8). The VO2 concerning 6MWT and 400mCWT were not significantly different (P=0.33) and were lower to the first ventilatory threshold determined by the stress test (P<0.001): 16.2±3.0 vs. 16.5±2.6 vs. 20.7±5.1mL·min-1·kg-1 respectively. The VO2 of the 200mFWT (20.2±3.7) was not different from the first ventilatory threshold. CONCLUSIONS: 400mCWT and 200mFWT are feasible, well-tolerated and reliable. They explore two levels of effort intensity (lower and not different to the first ventilatory threshold respectively). 400mCWT is a possible alternative to 6MWT. Associated with 200mFWT it should allow a better measurement of physical capacities and better customization of exercise training.
