Insights
Consistent passive range of motion (PROM) in the first year may prevent shoulder contractures in infants with brachial plexus birth injury (BPBI). Integrating PROM into daily routines aids adherence, while family factors can pose challenges.
Area of Science:
- Pediatrics
- Neurology
- Rehabilitation Medicine
Background:
- Brachial plexus birth injury (BPBI) can lead to shoulder contractures.
- Early intervention is crucial for managing BPBI complications.
- Passive range of motion (PROM) is a common therapeutic intervention.
Purpose of the Study:
- To evaluate the effectiveness of PROM in preventing shoulder contractures in infants with BPBI during their first year.
- To identify factors that help or hinder caregiver adherence to daily PROM exercises.
Main Methods:
- A pilot study involving five caregivers of children with upper trunk BPBI.
- Retrospective interviews to assess PROM frequency, facilitators, and barriers.
- Review of medical records for adherence and contracture development by age one.
Main Results:
- Three out of five children developed shoulder contractures, all with delayed or inconsistent PROM.
- Two children without contractures received consistent PROM throughout their first year.
- Consistent daily routine facilitated adherence; family context presented barriers.
Conclusions:
- Consistent PROM in the first year of life may be linked to the absence of shoulder contractures.
- Adherence to PROM can be improved by considering family routines and context.
Purpose:
This pilot study investigated the efficacy of passive range of motion (PROM) during the first year of life to prevent development of shoulder contractures in children with brachial plexus birth injury (BPBI) and identified facilitators and barriers to caregiver adherence with daily PROM.
Methods:
Five caregivers of children with upper trunk BPBI participated in retrospective interviews about the frequency with which they performed PROM during their child's first year of life including facilitators and barriers to daily adherence. Medical records were reviewed for documentation of caregiver-reported adherence and documented evidence of shoulder contracture by age one.
Results:
Three of the five children had documented shoulder contractures; all three had delayed initiation or inconsistent PROM in the first year of life. Two without shoulder contractures received consistent PROM throughout the first year of life. Making PROM part of the daily routine was a facilitator to adherence while family contextual factors were barriers.
Conclusion:
Absence of shoulder contracture may be related to consistent PROM throughout the first year of life; decreased frequency of PROM after the first month of life did not increase the risk of shoulder contracture. Consideration of family routines and context may facilitate adherence with PROM.
