Interrater reliability of face-to-face, tele- and video-based assessments with the modified Mallet classification in brachial plexus birth injuries.

The modified Mallet classification is widely used to measure motor function in brachial plexus birth injuries. The aim of the study was to investigate agreement and reliability of this classification under three different evaluation conditions: face-to-face; live tele-assessment; and delayed video-based assessment. A total of 100 children aged 4-15 years were included. Children were assessed by two raters except for live tele-assessment, which was performed by four raters. Agreement between the three different assessment conditions for the same rater were between strong and excellent for both raters 1 and 2. The interrater reliability for raters 1 and 2 under different assessment conditions was strong to excellent. Interrater reliability among the four raters was moderate to strong in tele-assessment. The modified Mallet classification may have appropriate reliability to be used in remote medical follow-up.Level of evidence: III.

Cut-off values of internal rotation in the glenohumeral joint for functional tasks in children with brachial plexus birth injury.

The aim of this study was to determine the cut-off values of the range of internal rotation motion in the isolated glenohumeral joint that is required for functional tasks in children with an upper root injury of the brachial plexus. Internal rotation motion was measured using a universal goniometer in 97 participants. The Mallet Hand to Spine and Mallet Hand to Belly tasks were assessed as functional tasks that require internal rotation of the shoulder. For the Hand to Spine task, 41° passive and 30° active internal rotation were necessary to reach the S1 level. For the Hand to Belly task, 42° passive and 29° active internal rotation were required to place the palm on the belly without wrist flexion. Of our participants, 97% could touch the belly with or without wrist flexion, but 28% could not reach S1 in the Hand to Spine task. The results of this study show the necessary amount of internal rotation of the shoulder that should be considered in treatment strategies.Level of evidence: III.

How does treadmill training contribute to botulinum toxin application plus routine physical therapy in ambulatory children with spastic bilateral cerebral palsy? A randomized controlled trial.

BACKGROUND: In spite of treadmill training and multilevel botulinum toxin (BoNT-A) injection being the two most commonly used treatment methods in pediatric rehabilitation management, there was no study investigating the effect of treadmill training after BoNT-A injection in children with cerebral palsy (CP). AIM: The aim of this study was to investigate the effect of treadmill training in addition to routine physical therapy after BoNT-A injection in ambulatory children with spastic bilateral CP on lower extremity muscle strength, selective motor control, and mobility. METHODS: A total of 30 spastic bilateral children with CP classified level II-III by the Gross Motor Function Classification System were randomly assigned the study and control groups. Both groups continued routine physical therapy treatments after multilevel BoNT-A injection into lower extremities, while the study group additionally underwent 8 weeks of treadmill training (20 min, two sessions per week). Handheld dynamometer, selective control assessment of lower extremity, temporospatial evaluation of gait, and Pediatric Evaluation of Disability Inventory were assessed before and after 8 weeks. RESULTS: In both groups, hip, knee, and ankle muscle strength increased at the end of 8 weeks (p < 0.05); however, in the study group, hip flexor/extensor muscle strength (p < 0.05, ES ≥ 0.50), selective motor control of ankle (p < 0.01, ES = 1.17), walking speed (p < 0.01, ES = 2.60), step lengths (p < 0.01, ES = 1.32), and mobility (p < 0.01, ES = 1.37) increased significantly compared to those of the control group. CONCLUSIONS: Treadmill training in addition to routine physical therapy after BoNT-A injection is beneficial for hip muscle strength, ankle selective motor control, walking quality, and functional mobility in the short term.

The functional health status of children with cerebral palsy during the COVID-19 pandemic stay-at-home period: a parental perspective.

BACKGROUND: Coronavirus disease 2019 (COVID-19) pandemic was effective all over the world. The stay-athome period was proposed to protect against the pandemic. The aim of this study was to investigate the effects of the COVID-19 pandemic stay-at-home period on body structures and functions, activity and participation levels, and environmental factors of children with cerebral palsy (CP) from the parental perspective in Turkey. METHODS: A twenty-question survey, using the International Classification of Functioning, Disability and Health for Children and Youth set to understand the functional changes of children with CP during the stay-athome period, was sent to parents in this prospective study. Motor function levels of children were determined by the Gross Motor Function Classification System parent report. The structural equation model was used for statistical analysis. RESULTS: One hundred and three parents of children with CP participated. At least one of four children with CP had increased levels of anxiety (41.8%), and increased level of a sensation of pain (34%) and sleep problems (25.2%). More than half of the children had increased tonus (67%), decreased range of motion (60.2%), decreased physical activity level (55.3%), and decreased support level of rehabilitation services (82.6%). During the stayat- home period activity and participation levels and environmental factors of children explained the changes of body functions as 70% and 33% (RMSEA=0.077, p < 0.05). CONCLUSIONS: This study is the first study to examine the functional health of children with CP biopsychosocially during the COVID-19 stay-at-home period. According to the parents, the functional health of children with CP was affected at different levels during the COVID-19 pandemic. Body functions may also be affected positively if physical activity level, home program and environmental supports increase.
