Early Mobilization and Equinus Correction in Spastic Cerebral Palsy

Cerebral Palsy (CP) is a condition characterized by a permanent motor function impairment resulting from brain injury occurring before, during, or after birth. Spastic CP accounts for approximately 70-80% of all cases, and equinus deformity is the most common deformity in the lower extremities due to increased muscle tone. Equinus deformity leads to limited ankle dorsiflexion and gait abnormalities, thereby negatively affecting functional independence. Gastrotenotomy is frequently performed in the surgical management of this deformity; however, there is no consensus in the literature regarding the duration of postoperative immobilization, AFO-use protocols, or the optimal timing of mobilization.

Early postoperative mobilization is suggested to support the remodeling of the muscle-tendon unit, increase joint range of motion, and prevent muscle shortening and contracture development. Nevertheless, controlled studies investigating the effect of early mobilization on equinus correction following gastrotenotomy in children with CP are highly limited. Therefore, the aim of this study is to evaluate the effects of early postoperative mobilization on equinus deformity correction and gross motor function improvement in children with spastic-type CP. The results are expected to contribute to the standardization of postoperative rehabilitation protocols and to support evidence-based decision-making in clinical practice.

Inclusion criteria

• Diagnosis: Children diagnosed with spastic-type Cerebral Palsy (CP).
• Age Range: Participants aged between 4 and 14 years.
• Functional Level: Children with Gross Motor Function Classification System (GMFCS) levels I-II (able to walk independently or with minimal assistance).
• Surgical Indication: Scheduled for orthopedic surgery (gastrotenotomy) due to equinus deformity.
• Cognitive Status: Sufficient cognitive capacity to understand verbal instructions.
• Parental Consent: Written informed consent obtained from parents or legal guardians.

Exclusion criteria

• Other CP Types: Children diagnosed with dyskinetic, ataxic, or mixed-type CP.
• Functional Level: Participants with GMFCS levels III, IV, or V (unable to walk independently or dependent on a wheelchair).
• Concomitant Orthopedic Problems: Presence of hip dysplasia, scoliosis, or severe lower extremity contractures that may affect gait patterns.
• Neuromuscular or Other Diseases: Presence of non-CP neuromuscular disorders (e.g., muscular dystrophy, peripheral neuropathy).
• Previous Surgery: History of tendon lengthening or muscle release surgery in the same lower extremity.
• Postoperative Complications: Development of surgical site infection, excessive pain, or conditions requiring reoperation.
• Noncompliance with Rehabilitation: Inability to attend prescribed physical therapy and rehabilitation sessions regularly or poor adherence to the treatment program.
