Objective Lower limb deformity in children with cerebral palsy (CP) is a common musculoskeletal problem and planovalgus is the most prevalent, characterized by talus median subluxation, calcaneal valgus, and supinated forefoot. According to studies, one issue in orthopedics and pathology is the accurate diagnosis and proper treatment of planovalgus deformity in children with bilateral spastic cerebral palsy, which has attracted researchers’ attention. Accordingly, the present study investigates the effect of planovalgus deformity on the motor performance and balance of these children.
Materials & Methods This cross-sectional study employed a descriptive-analytical design. The convenient sampling method was used among children with bilateral spastic cerebral palsy, diagnosed with unilateral planovalgus, who were referred to the clinics of the University of Social Welfare and Rehabilitation Sciences (Nezam Mafi) and occupational therapy clinics from September 2022 to February 2023 in Tehran City, Iran. Meanwhile, all participants were willing to cooperate in this research. A total of 27 participants were evaluated by an occupational therapist based on the specified criteria and gross motor function classification system (GMFCS), which included the assessments of balance, muscle strength, range of motion, and pain. Data analysis was done using the SPSS software, version 16.
Results The results revealed a statistically significant difference between the mean range of motion of ankle dorsiflexion and knee extension between the two limbs (P<0.001). The mean muscle strength of the quadriceps and ankle plantar flexors indicated a statistically significant difference in the affected limb (P<0.001). Additionally, the mean displacement of the center of pressure of the foot also demonstrated a statistically significant difference regarding topographical involvement (P<0.001).
Conclusion Planovalgus deformity is one of the most common ankle deformities, which is of great concern for children with cerebral palsy. The results obtained from the assessments of the child’s balance and motor function demonstrated the importance of assessment strategies and early interventions to achieve better rehabilitation outcomes for children with CP and planovalgus deformity.
