Reliability of the gross motor function measure for children with osteogenesis imperfecta

Abstract: Purpose: The Gross Motor Function Measure (GMFM) is a criterion-referenced evaluative measure designed to detect change over time for children diagnosed with cerebral palsy (CP). Reliability of this measure has not been tested for children with osteogenesis imperfecta (OI). The purpose of this study was to determine the intra- and interrater reliabilities of the GMFM for use with children diagnosed with OI. Method: One physical therapist administered and scored the GMFM for 19 children with OI who were followed at the Shriners Hospital for Children. The assessments were videotaped, then viewed and scored by five physical therapists, including the author, at least six weeks later. Intra- and interrater reliabilities were assessed using intraclass correlation coefficients (ICCs). Kappa statistics were calculated for items demonstrating more disagreement than the majority. Results: The ICCs for intrarater reliability of the five dimensions and total score were 0.99. The ICCs for interrater reliability were 0.98 for the lying and rolling dimension and 0.99 for the other dimensions and total score. Kappa statistics for items demonstrating more disagreement than the majority ranged from 0.552 to 1.00. Conclusions: This study provides evidence of the reliability of the GMFM for children with OI when scored by pediatric physical therapists familiar with the measure. The videotape provided a consistent situation because each therapist did not directly interact with each child, but rather rated a videotaped session of the child’s performance.

Clinical assessment of ankle plantarflexor spasticity in adult patients after stroke: inter-and intra-rater reliability of the Modified Tardieu Scale.

Abstract: Primary objective: To evaluate the reliability of the Modified Tardieu Scale (MTS) in the measurement of ankle plantarflexor spasticity in patients after stroke.Research design: Inter- and intra-rater reliability study.Interventions: Not applicable.Methods and procedures: Adult patients after stroke participated. Patients were tested by two raters for inter-rater reliability. Patients were re-tested by one rater at least 1 week later for intra-rater reliability. The plantarflexors on the hemiparetic side were tested.Main outcomes and results: The ICCs of inter and intra-rater reliability across all components of MTS were moderate and moderately high (range 0.40–0.71). Inter- and intra-rater reliability for the dynamic component of spasticity (R2–R1) were moderate (ICC = 0.57 and 0.40, respectively). The difference between the two raters for R2 was statistically significant (p = 0.001).Conclusions: The reliability of the Modified Tardieu Scale in the measurement of ankle plantarflexor spasticity in adult p...

Rater agreement for the Rey‐Osterrieth Complex Figure Test

Abstract: This report assesses the intrarater and interrater reliability of quantitatively scoring the Rey-Osterrieth Complex Figure Test (RCF). The intrarater correlation coefficients were .96, .99, and .96, and the interrater correlation coefficients were .88, .97, and .96 for the Copy, Immediate Recall, and Delayed Recall, respectively. However, statistically significant mean differences in score were found between raters on the Copy, Immediate, and Delayed Recall. Though the majority of structural units within the RCF are reliably scored, several units had a greater magnitude of observed scoring differences compared to the other units after adjusting for expected differences. Overall, reliability estimates demonstrate high intrarater reliability and acceptable interrater reliability except for the potential for systematic scoring differences.

Scoring reliability of the multiple sleep latency test in a clinical population.

Abstract: Study Objectives: To determine intrarater and interrater scoring reliability of the multiple sleep latency test (MSLT) in a population of sleep clinic patients. Design: N/A Setting: Urban sleep center. Patients: 200 consecutive sleep center patients (diagnoses included: obstructive sleep apnea, narcolepsy, periodic-limb-movement, and individuals with no diagnosis). Interventions: N/A Measurements and Results: MSLTs were recorded and scored according to standard clinical procedures. One of four clinical polysomnographers and one of seven polysomnographic technologists scored each MSLT. All MSLTs were then rescored by the same polysomnographer. The intrarater reliability coefficient for mean MSLT score was .87 and interrater reliability was .90. Coefficients for the mean number of REM onsets during the MSLT were .81 for intrarater and .88 for interrater reliability. Intrarater and interrater agreement (kappa coefficients) for the presence of at least one REM onset during the MSLT was .78 and .86, respectively. For the presence of greater than one REM onset, a kappa of .78 was obtained for intrarater agreement and .91 for interrater agreement. Conclusions: The clinical MSLT displays excellent interrater and intrarater reliability estimates for both sleep latency and REM onset scores in a sleep-disordered population.
