Does physical therapy improve outcome in infants with joint hypermobility and benign hypotonia?

This study examined the effect of the frequency of physical therapy on the outcome of infants referred for delayed motor development due to joint hypermobility and benign hypotonia. The study groups comprised 29 infants (8-12 months) who were randomly placed into a monthly and weekly treatment groups. No difference was found between the 2 study group scores on the different tests at all assessment points. However, assessment of walking at the age of 15 months revealed a clear advantage of the infants who were treated weekly. Our study demonstrated a minor benefit of weekly treatment protocol only in the achievement of independent walking in children with joint hypermobility and benign hypotonia. It did not prove an advantage of weekly physical therapy. It seems that monthly physical therapy combined with a home treatment protocol implemented by the primary caregivers is sufficient to achieve motor catch-up.
