PURPOSE: This study aimed to describe Early Activity Scale for Endurance (EASE) scores and 6-minute walk test (6MWT) distances of children with cerebral palsy (CP) by functional ability level, sex, and age and to examine the convergent validity of the 2 tests. METHODS: A total of 708 participants with CP, Gross Motor Function Classification System (GMFCS) levels I to V, completed the EASE, and 376 of the study participants (3-12years), GMFCS levels I to III, completed the 6MWT. RESULTS: Children with CP vary in EASE scores and 6MWT distances based on GMFCS level and, to a lesser extent, age. The EASE and the 6MWT demonstrate a statistically significant but low, positive correlation. CONCLUSIONS: Understanding the relationship between these outcomes and GMFCS levels and age assists clinicians in establishing plans of care targeted at improving endurance for activity and functional walking capacity for children with CP.

OBJECTIVES: Validity of the Early Clinical Assessment of Balance (ECAB), to monitor postural stability in children with cerebral palsy (CP), was evaluated. METHODS: 410 children with CP, 1.5 to 5 years old, participated. Physical therapists scored children on the Movement Assessment of Infants Automatic Reactions section and Pediatric Balance Scale. Through consensus, researchers selected items from both measures to create the ECAB. Content and construct validity were examined through item correlations, comparison of ECAB scores among motor ability, age and gender groups and correlations with the Gross Motor Function Measure 66 basal and ceiling (GMFM-66-B&C). RESULTS: Internal consistency was high (Cronbach's alpha = 0.92). ECAB differed significantly among motor ability, children <31 months old scored lower than older children, but there was no difference between boys and girls. ECAB and GMFM-66-B&C scores correlated strongly (r = 0.97). CONCLUSION: Validity of the ECAB was supported. Reliability and responsiveness need study.

PURPOSE: The Early Activity Scale for Endurance (EASE) was developed as a clinically feasible measure of endurance for physical activity in young children with cerebral palsy (CP). Validity and reliability were evaluated. METHODS: Participants included 414 children with CP and 106 without CP. Parents completed the EASE, an 11-item self-report measure. For construct validity, EASE scores were compared by Gross Motor Function Classification System levels (0 assigned for children without CP), age, and gender. In subgroups, convergent validity with the 6-minute walk test and test-retest reliability with a second EASE were evaluated. RESULTS: EASE scores differed significantly by Gross Motor Function Classification System, but not by age or gender. The EASE correlated moderately (rs = 0.57) with the 6-minute walk test. Test-retest reliability was high, intraclass correlation (2,1) = 0.95. CONCLUSION: The EASE has acceptable psychometrics for use in practice and research to estimate endurance for physical activity in young children with CP.

PURPOSE: To highlight key considerations for planning and implementing multisite research based on experiences and reflections in conducting a large, international, multisite study. DESCRIPTION: Successes and challenges encountered throughout a multisite study process, and collective recommendations for future researchers are presented. Considerations addressed include creation of the research team and a "community of practice," study preparation and management time, approval by institutional review boards, training of future researchers, recruitment and retention of participants, and dissemination and translation of study materials to consumers. IMPORTANCE TO MEMBERS: Multisite research has the potential to create knowledge for pediatric physical therapy through collaboration among knowledgeable researchers and expert practitioners and by increasing the potential for generalization of findings. Effective planning, including anticipation of challenges, is critical to a successful study. Our collective experiences may assist practitioners and researchers in planning, implementing, and completing future multisite studies.

PURPOSE: To describe and evaluate the effects of motor control intervention in young children diagnosed with idiopathic toe walking. METHODS: Five children received motor control intervention in a multiple-case series design using a nonconcurrent, variable baseline. Multiple gait measures were taken before and during the intervention phase. Pre- and posttreatment measures of gross motor development and ankle dorsiflexion range of motion were compared. RESULTS: During the intervention phase, heel strike frequency showed an upward slope for 1 participant, slight upward trends for 3 participants, and no change for 1 participant. Parents indicated minimal gait change within the children's regular environments. Gross motor skill scores increased but were not statistically significant. Passive ankle range of motion improved and was maintained (P = .002). CONCLUSIONS: Presentation of children with idiopathic toe walking varies and refinement is needed for gait measures and assessment methods. Intervention improved ankle mobility, but additional components appear necessary to attain spontaneous heel-toe gait.

A standardized protocol for a pediatric heel-rise test was developed and reliability and validity are reported. Fifty-seven children developing typically (CDT) and 34 children with plantar flexion weakness performed three tests: unilateral heel rise, vertical jump, and force measurement using handheld dynamometry. Intraclass correlation coefficients (ICC) varied from 0.85-0.99 for reliability analyses in both participant groups. Construct validity analysis revealed a significant difference between groups (F = 44.57, p < .05) and age-related differences among CDT; 5- to 8-year olds (mean = 15.2, SD = 5.4) performed fewer repetitions compared to 9- to 12-year olds (mean = 27.7, SD = 11.7) (p < .05). Age explained 41% of the variance in the number of heel-rise repetitions. Correlations between the three tests (r = 0.56 to 0.66) provide evidence of convergent validity. The results indicate that the standardized protocol is both reliable and valid for use in 5- to 12-year-old children with and without plantar flexion weakness.
