Schmidt SM, et al. - Utilizing data from the Swedish follow-up program and national registry Cerebral Palsy Follow-Up Program, the authors carried out this retrospective cohort registry study to investigate the links between pain in the lower extremities (feet, knees, and hips) and back, and spasticity, bone/joint complications, and mobility. Three thousand two hundred fifty-six candidates with cerebral palsy (aged 2.5 to 16 years) participating in the Swedish Cerebral Palsy Follow-Up Program were involved. When controlling for sex, bone/joint complications (range of motion, windswept posture, and scoliosis) and reduced mobility were linked to pain in the lower extremities. Data reported that the R² of the model was 0.15. In children with cerebral palsy, other factors not included in the model, considering the model's R2, are also related to pain in lower extremities.
