The log rank test is a popular nonparametric test for comparing survival distributions among groups. When data are organized in clusters of potentially correlated observations, adjustments can be made to account for within-cluster dependencies among observations, eg, tests derived from frailty models. Tests for clustered data can be further biased when the number of observations within each cluster and the distribution of groups within cluster are correlated with survival times, phenomena known as informative cluster size and informative within-cluster group size. In this manuscript, we develop a log rank test for clustered data that adjusts for the potentially biasing effect of informative cluster size and within-cluster group size. We provide the results of a simulation study demonstrating that our proposed test remains unbiased under cluster-based informativeness, while other candidate tests not accounting for the clustering structure do not properly maintain size. Furthermore, our test exhibits power advantages under scenarios in which traditional tests are appropriate. We demonstrate an application of our test by comparing time to functional progression between groups defined initial functional status in a spinal cord injury data set.

“…Therefore, the item may actually test the training team's ability to hold a person in the appropriate posture, instead of the person's true ability to maintain this posture. Furthermore, in other studies, 14,15 test-retest and interrater reliabilities were shown to be low for Stand retraining, and most subjects had a ceiling effect for this item.…”

“…14,18 The Pediatric NRS was adapted from the adult Neuromuscular Recovery Scale (NRS). 18,[40][41][42][43][44] Content validity 14 and good interrater reliability 45 have been determined for children 2-12 years old. It assesses neuromuscular capacity in the context of 10 tasks that may be performed in the clinical environment.…”

“…While responsiveness of the SATCo for the pediatric population post SCI has been established and shown to have a significantly larger effect size 16 compared to other typical trunk control and balance measures (eg, modified functional reach, Berg Balance Test), content validity 14 and interrater reliability 45 have been determined for the Pediatric NRS. The adult NRS, also applied to adolescents older than 13 years old, has been tested and determined to have good test-retest reliability, 40 good interrater reliability, 41 responsiveness in the outpatient setting, 43 and validity. 42 Testing of psychometric properties (eg, test-retest reliability, responsiveness) for the Pediatric NRS has yet to be conducted and is forthcoming.…”

Background: Activity-based therapies aim to improve neuromuscular capacity after spinal cord injury (SCI). Objective: The purpose of this prospective study was to report the impact of Activity-based Locomotor Training (AB-LT) on neuromuscular capacity in pediatric patients with SCI. Methods: Participants were enrolled for their first episode of AB-LT for a minimum of 60 daily, 1.5-hour sessions. The Segmental Assessment of Trunk Control (SATCo) and the Pediatric Neuromuscular Recovery Scale (Pediatric NRS) were assessed initially, every 20 sessions, and post 60 sessions. Results: Twenty-six consecutive patients, mean age 5 years (SD = 3), completed a mean 55 sessions (SD = 4) within 63 weekdays (SD = 9). The Pediatric NRS total score improved significantly, adjusted mean 11.4, from initial to post-60 sessions (p < .05) with an average adjusted evaluation-toevaluation 3.7 change. SATCo scores improved significantly across 60 sessions, mean change 5.2, an estimated 1.7 change between evaluations (p < .05). Age at enrollment and chronicity had no effect; however, initial neuromuscular capacity scores were negatively correlated with change scores (p < .05). Conclusion: Sixty AB-LT sessions significantly improved trunk and neuromuscular capacity in children with SCI, regardless of age or chronicity at enrollment. Patients with lower initial scores made greater improvements than patients with higher initial neuromuscular capacity. Anecdotal parent reports of their child's functional change in the home and community highlight the synergy between quantitative change in neuromuscular capacity and meaningful, improved quality of life and the need for formal investigation of this relationship.
