TL;DR: NTSB seems to be reliable in test-retest, but some learning effect was noticed and junior players showed less core stability and more trunk and shoulder mobility than senior players.
Abstract: Background Injuries are common in handball, but little is known about their risk factors. One potential screening test to identify player at risk is the Nine Test Screening Battery (NTSB). Objective To test the intra-rater reliability of the NTSB and compare the results from NTSB between subgroups in the cohort. Design Test-retest design used for the intra-rater reliability test of NTSB. Experimental design used for testing senior and national team players. Setting Icelandic male handball players. Participants A total of 50 junior players from 5 clubs participated in the intra-rater reliability test. Also, 115 seniorplayers from 13 of 16 teams in the two highest divisions in Iceland and 26 Icelandic national team players (8 playing abroad), participated. Main outcome of measurement Intra-rater reliability of NTSB. Difference in NTSB scores between subgroups. Results There was a strong intra-rater correlation between the test-retest sessions, ICC: 0.95 T1: 21.6±3.5 (95% CI: 20.7–22.6), T2: 22.0±3.4 (95% CI: 21.0–22.9). The retest had significantly higher total score than the first test (P=.041), indicating some learning effect. No difference was found in total score of NTSB between teams, level of play or different age and height groups. However, goalkeepers had higher total score than other players (P=.001). Observing NTSB separately, junior players had significantly less core stability than senior and national team players (tests 5-7, P≤.006) and more mobility in trunk and shoulders (tests 8-9, P Conclusions NTSB seems to be reliable in test-retest, but some learning effect was noticed. Junior players showed less core stability and more trunk and shoulder mobility than senior players.

TL;DR: In this article, the inter-and intra-rater reliability of the head-shaft angle (HSA) on radiographs from a surveillance program for children with cerebral palsy (CP) was analyzed.
Abstract: Purpose The purpose of this study was to analyse inter- and intra-rater reliability of the Head-Shaft angle (HSA) on radiographs from a surveillance programme for children with cerebral palsy (CP). Method A high HSA is a risk factor for hip displacement in children with CP. To evaluate inter- and intra-rater reliability of the HSA, hip radiographs from the CP surveillance programme CPUP in the southern part of Sweden during the first half of 2016 were included in this study. Results We analysed 50 radiographs from children in Gross Motor Function Classification System (GMFCS) levels II-V with a mean age of 6.6 (SD 3.2) years from 11 different radiology departments. Three raters measured the HSA of one hip at baseline and after four weeks. Intra-Class Correlation Coefficient (ICC) showed excellent inter- and intra-rater reliability of the HSA with ICC 0.92 (95% CI 0.87–0.96) and ICC 0.99 (95% CI 0.98–0.99) respectively. Conclusion We conclude that the HSA, important when predicting hip displacement in CP, showed high inter-and intra-rater reliability when analysed on radiographs from various radiology departments in a surveillance program for CP.
