Background: Cerebral palsy seems to be more common in term babies whose birthweight is low for their gestational age at delivery, but past analyses have been hampered by small datasets and Z-score calculation methods.
Methods: We compared data from ten European registers for 4503 singleton children with cerebral palsy born between 1976 and 1990 with the number of births in each study population. Weight and gestation of these children were compared with reference standards for the normal spread of gestation and weight-for-gestational age at birth.
Findings: Babies of 32-42 weeks' gestation with a birthweight for gestational age below the 10th percentile (using fetal growth standards) were 4-6 times more likely to have cerebral palsy than were children in a reference band between the 25th and 75th percentiles. In children with a weight above the 97th percentile, the increased risk was smaller (from 1.6 to 3.1), but still significant. Those with a birthweight about 1 SD above average always had the lowest risk of cerebral palsy. A similar pattern was seen in those with unilateral or bilateral spasticity, as in those with a dyskinetic or ataxic disability. In babies of less than 32 weeks' gestation, the relation between weight and risk was less clear.
Interpretation: The risk of cerebral palsy, like the risk of perinatal death, is lowest in babies who are of above average weight-for-gestation at birth, but risk rises when weight is well above normal as well as when it is well below normal. Whether deviant growth is the cause or a consequence of the disability remains to be determined.

Aim: To identify developmental trajectories of impaired hand function in infants aged 3 to 15 months with unilateral cerebral palsy (CP).
Method: Sixty-three infants (37 male; median gestational age 37 weeks [interquartile range 30-39.1 weeks]) recruited as part of a randomized trial with a confirmed diagnosis of unilateral CP were included.

Aim: To systematically review the prevalence and incidence of osteoporosis, osteopenia, low bone mass, and fragility fracture in adults with cerebral palsy (CP), and identify the risk factors for osteoporosis and fracture.
Method: A systematic literature search was performed in the MEDLINE, PubMed, CINAHL, AMED, Cochrane Reviews, EMBASE, and EBM database reviews from inception until May 2024. Search terms covered a combination of keywords for CP, fracture, osteoporosis, incidence and prevalence, and risk factors.

Objective: This study aimed to describe the monitoring of treatment fidelity in a pragmatic pediatric rehabilitation trial using the National Institutes of Health Behavior Change Consortium framework, and to identify child and therapist factors that influence treatment fidelity.
Methods: Therapists (n = 28) were trained in the key ingredients (1-on-1, functional, goal-directed, motor learning intervention) and study protocol for a comparative effectiveness trial titled: A Comparison: High Intensity periodic vs. Every week therapy in children with cerebral palsy (ACHIEVE) for children ages 2 to 8 years with cerebral palsy.

Spasticity affects up to 80% of individuals with cerebral palsy and can lead to pain and difficulties with performing activities of daily living. If left untreated, spasticity can progress to contracture and neuro-orthopedic deformities. Cryoneurolysis is an emerging and mini-invasive ultrasound-guided technique that causes secondary axonotmesis of peripheral nerves through the formation of an ice ball and may result in months to years of improved range of motion and reduced pain in patients with spasticity.
