How brachial plexus birth palsy affects motor development and upper extremity skill quality?

The Relationship Between Postural Torticollis Abnormalities and Plagiocephaly on the Early Motor Development Milestones of Lying and Rolling Activities in Infants: A Retrospective Study

The study examined how neck muscle imbalance and plagiocephaly affect the lying and rolling activities in 118 infants aged 4 to 6 months with postural torticollis. Outcome measures included age, sex, cervical movement, and plagiocephaly severity. Neck muscle function was assessed with the Muscle Function Scale (MFS), and infant motor abilities in lying and rolling were evaluated through the corresponding dimensions of the Gross Motor Function Measure (GMFM). Multiple regression analysis showed that a better MFS score of the affected neck was significantly associated with improved lying and rolling activities in the GMFM (p < .01), and importantly, the interaction between the plagiocephaly and the MFS scores of the affected neck muscle in these activities was found to be significant (p < .05). These results highlight the need for early intervention in infants with torticollis to address muscle imbalance and plagiocephaly, crucial for early motor development (KCT0008367).

Quality of upper extremity skills and disability inventory via manual ability classification in children with neonatal brachial plexus palsy

PURPOSE

The aim of study was to investigate the relationship between upper extremity skill quality and disability inventory according to manual ability classification system in children with neonatal brachial plexus palsy (NBPP).

MATERIALS AND METHODS

Children with NBPP were included between the ages of 4-7.5 years. Children were classified in Manual Ability Classification System (MACS). Upper extremity skill quality was evaluated with Quality of Upper Extremity Skills Test (QUEST), disability status was assessed with Pediatric Evaluation of Disability Inventory (PEDI).

RESULTS

Total of 63 children (girls:31/boys:32), and mean age was 6.32 ± 1.73 years. 37 (58.73%) of children were at MACS Level-2. According to MACS classification, significant differences were noted in PEDI scores (p = 0.001), dissociated movements (p = 0.016) and grasp (p = 0.002) domains of QUEST. However, no significant differences between QUEST total scores (p = 0.079). PEDI (ROC; AuC = 0.762) and QUEST total score (ROC; AuC = 0.714) were sensitive to difference between groups across MACS in children with NBPP.

CONCLUSION

The PEDI and QUEST are sensitive in distinguishing the disability of children with NBPP at different MACS levels. Assessment of children with NBPP is not limited to functionality, disability, and quality of movement, it is multidimensional. Outcomes measures studies of movement's quality in children with NBPP are needed.

Early Spontaneous Movements and Upper Extremity Movement Score in Infants With all Narakas Types of Obstetric Brachial Plexus Palsy

BACKGROUND

Obstetric brachial plexus palsy (OBPP) is a birth injury that affects upper extremity performance. However, some children with OBPP might have central nervous system disorder or developmental disabilities. This study aimed to investigate (1) the early spontaneous movements using General Movements Assessment (GMA) in infants with OBPP according to the Narakas classification, (2) the differences from typical infants, and (3) the relationship between the GMA and the affected upper extremity movements score.

METHODS

Fifty-six infants with OBPP (39 females; median gestational age 40 weeks, range = 34 to 42) and 50 typical infants (20 females; median gestational age 38 weeks, range = 37 to 41) were assessed at age three to five months using the GMA, which is a determined Motor Optimality Score (MOS) for fidgety movements and concurrent motor repertoire, and using the Active Movement Scale (AMS) for affected upper extremity movements.

RESULTS

There were no differences in MOS and its subcategories between Narakas types in infants with OBPP (P > 0.05); however, infants with OBPP had a higher degree of aberrant fidgety movements and a lower score in MOS and its subcategories than typical infants (P < 0.05). There was no relationship between AMS scores, and MOS and its subcategories.

CONCLUSIONS

Infants with OBPP, except Narakas type I, might have an increased risk of central nervous disorder and developmental problems in addition to peripheral nerve injury. Each test, GMA and AMS, contributes to the identification of their own specific risk in these infants.
