Spina bifida (SB) is one of the most common congenital malformations. It is caused by a failed closure of one or more vertebrae during the early weeks of gestation and results in significant neurological impairment at or below the lesion site (Copp et al., 2015). SB is the most complex of the congenital disorders that infants are expected to survive (Phillips et al., 2017); approximately 85% of individuals with SB are expected to survive to adulthood owing to medical advances (Spina Bifida Association, 2018). However, despite the advances in medical care and treatment, patients with SB continue to experience a range of functional impairments in areas such as walking and voluntary bowel and bladder control (Şahiṅ et al., 2014).
