BMI, selective control assessment of the lower extremity and pediatric functional independence measure (WEE FIM) were used to assess BMI, SVMC and functional independence, respectively.<br> <strong>Results</strong>: The data demonstrated the presence of a positive strong significant correlation between selective control assessment of the lower extremity and WEE FIM. On the other hand, there was a negative, significant correlation between WEE FIM and BMI. In addition, a negative moderate considerable correlation between BMI and selective control assessment of the lower extremity was detected<br> <strong>Discussion</strong>: Functional independence is significantly correlated with BMI and SVMC in children with spastic diplegic CP. BMI and SVMC are major factors that influence functional independence in these children. So, they are highly recommended to be part of the evaluation of the functional independence of children with spastic diplegia in clinical settings and research.</span></span></span></div> Body mass index, Cerebral palsy (CP), Diplegia, Functional independence, Selective voluntary motor control (SVMC) 655 662 http://irj.uswr.ac.ir/browse.php?a_code=A-10-1955-2&slc_lang=en&sid=1 Alaa AL-Nemr alaaalnemr28@cu.edu.eg 0000-0001-8184-5010 Yes Department of Physical Therapy for Pediatrics, Faculty of Physical Therapy, Cairo University, Giza, Egypt.
