Frequency, facilitators, and barriers for range of motion to prevent shoulder contracture in brachial plexus birth injury: A pilot study.

Only five caregivers participated, all were mothers, and all children had an upper trunk brachial plexus injury, so the sample is very small and may not represent other families. The participants were known to the researchers, which may bias responses. The study relied on retrospective recall, and at least one caregiver's report conflicted with medical records. The children also received occupational therapy at least once per week, so the study cannot determine whether PROM frequency alone mattered. The paper is a pilot and states that additional research is needed before making generalizations.

Do not conclude that stretching at every diaper change prevents shoulder contracture. This was a pilot with five caregivers, the children also received occupational therapy at least once per week, and the paper states that additional research is needed before making generalizations.
