Interrater reliability for unilateral and bilateral tests to measure the popliteal angle in children and youth with cerebral palsy

Abstract Background Short hamstring muscles can cause several problems for children with cerebral palsy. The results of the clinical measurement of hamstring length are often used in decision-making about treatment of children with cerebral palsy. There are different ways of performing this measurement. The aim of this study was to evaluate the interrater reliability of the unilateral and bilateral measurement of the popliteal angle in children and youth with cerebral palsy. Methods Two methods for estimating hamstring length using unilateral and bilateral measurements of the popliteal angle were applied in children with cerebral palsy. Both tests were applied bilaterally by two independent examiners on the same day for each child. The intraclass correlation coefficient (ICC) was calculated to evaluate the interrater reliability of both measurements. Seventy young people with cerebral palsy (32 females, 38 males, mean age 10 years 8 months, range 5–22 years) at Gross Motor Function Classification System levels I (n = 17), II (n = 31), III (n = 12) and IV (n = 10) were included. Results The interrater reliability was good for both measurements. The ICC values were 0.80 on the right and 0.86 on the left for the unilateral popliteal angle, and 0.82 on the right and 0.83 on the left for the bilateral popliteal angle. Conclusions Both unilateral and bilateral measurement of the popliteal angle is a reliable method for estimating hamstring length in children and youth with cerebral palsy.

Background/Aims The ability to eat and drink is the most important factor in health, survival and longevity. Children with cerebral palsy can suffer from severe dysphagia, which can lead to a high risk of aspiration and choking. As classifying eating and drinking ability in children with cerebral palsy is important in research and treatment, the aim of this study was to determine the cross-cultural validation and reliability of the Persian version of the Eating and Drinking Ability Classification System. Methods After translation procedures, the face validity, content validity, test–retest reliability and interrater reliability of the Eating and Drinking Ability Classification System were evaluated. In total, 130 parents of children with cerebral palsy and 34 therapists participated in the evaluation of the scale's reliability. The 73 boys and 57 girls with cerebral palsy were aged 3–20 years (mean age 4.4 years) and had various types of cerebral palsy. They were classified according to the Eating and Drinking Ability Classification System by both their parents and the therapists. Results The overall results indicated that the words and sentences used were simple, clear, understandable, relevant and necessary. The intraclass correlation coefficients for test–retest reliability for parents, occupational therapists and speech therapists were 0.98, 0.98 and 0.995, respectively. The interrater reliability between parents and occupational therapists was 0.96, between parents and speech therapists was 0.95, and between occupational therapists and speech therapists was 0.985. Conclusions The Persian version of the Eating and Drinking Ability Classification System seems to be valid and reliable. This system may be used to evaluate children with cerebral palsy.

Abstract Background and Purpose. The purpose of this study was to examine the reliability and validity of data obtained with 2 newly developed shuttle run tests (SRT-I and SRT-II) to measure aerobic power in children with cerebral palsy (CP) who were classified at level I or II on the Gross Motor Function Classification System (GMFCS). The SRT-I was developed for children at GMFCS level I, and the SRT-II was developed for children at GMFCS level II. Subjects. Twenty-five children and adolescents with CP (10 female, 15 male; mean age=11.9 years, SD=2.9), classified at GMFCS level I (n=14) or level II (n=11), participated in the study. Methods. To assess test-retest reliability of data for the 10-m shuttle run tests, the subjects performed the same test within 2 weeks. To examine validity, the shuttle run tests were compared with a GMFCS level–based treadmill test designed to measure peak oxygen uptake. Results. Statistical analyses revealed test-retest reliability for exercise time (number of levels completed) (intraclass correlation coefficients of .97 for the SRT-I and .99 for the SRT-II) and reliability for peak heart rate attained during the final level (intraclass correlation coefficients of .87 for the SRT-I and .94 for the SRT-II). High correlations were found for the relationship between data for both shuttle run tests and data for the treadmill test (r=.96 for both). Discussion and Conclusion. The results suggest that both 10-m shuttle run tests yield reliable and valid data. Moreover, the shuttle run tests have advantages over a treadmill test for children with CP who are able to walk and run (GMFCS level I or II). [Verschuren O, Takken T, Ketelaar M, et al.

Test Retest Reliability

Background. Children with cerebral palsy often suffer from a lack of balance compared with typically developing children. Because balance capacity is relevant to functional activities, reliable and valid functional balance measures are crucial for the pediatric clinical setting. Objective. This study examined the reliability and validity of 3 functional balance measures. Methods. Thirty children aged 60 to 142 months with Gross Motor Function Classification System (GMFCS) levels of I to IV were recruited. For test-retest reliability, the same physical therapist administered the Functional Reach Test (FRT), Berg Balance Scale (BBS), and Timed Up and Go (TUG) twice. For interrater reliability, the testing processes were video recorded and later scored by another therapist. For convergent validity, children with cerebral palsy received the Gross Motor Function Measures (GMFM), walking speed, and 10-second sit-to-stand test within 1 week and the results evaluated. Results. The 3 functional balance measures had excellent test-retest reliability (intraclass correlation coefficient [ICC] >0.95) and interrater reliability (ICC = 0.98-1.00). With regard to convergent validity, the BBS and the TUG were highly correlated with GMFM total score, walking speed, and the 10-second sit-to-stand test. The discriminate validity indicates that the FRT can distinguish children with cerebral palsy with different GMFCS levels, whereas the BBS total score and TUG failed to distinguish between children with cerebral palsy with GMFCS levels of I and II. Conclusion. The 3 functional balance measures are simple, valid, and reliable for examining children with cerebral palsy and are thus suitable for clinical practice.

Stage Renal Disease

Autosomal dominant polycystic kidney disease (ADPKD) eventually leads to end stage renal disease (ESRD) with an increase in size and number of cysts over time. Progression to ESRD has previously been shown to correlate with total kidney volume (TKV). An accurate and relatively simple method to perform measurement of TKV has been difficult to develop. We propose a semi-automated approach of calculating TKV inclusive of all cysts in ADPKD patients based on b0 images relatively quickly without requiring any calculations or additional MRI time. Our purpose is to evaluate the reliability and reproducibility of our method by raters of various training levels within the environment of an advanced 3D viewer. Thirty patients were retrospectively identified who had DWI performed as part of 1.5T MRI renal examination. Right and left TKVs were calculated by five radiologists of various training levels. Interrater reliability (IRR) was estimated by computing the intraclass correlation (ICC) for all raters. ICC values calculated for TKV measurements between the five raters were 0.989 (95% CI = (0.981, 0.994), p < 0.01) for the right and 0.961 (95% CI = (0.936, 0.979), p < 0.01) for the left. Our method shows excellent intraclass correlation between raters, allowing for excellent interrater reliability.
