The aim of this study is to investigate the effect of early postoperative mobilization on the correction of equinus deformity and the improvement of motor functions following gastrotenotomy in children with spastic-type Cerebral Palsy (CP).

H1: Early postoperative mobilization combined with AFO use after gastrotenotomy in children with spastic CP has a significant effect on equinus correction and motor function improvement.

H0: Early postoperative mobilization combined with AFO use after gastrotenotomy in children with spastic CP has no significant effect on equinus correction or motor function improvement.

The study is designed as a prospective, comparative clinical investigation. Children aged 4-14 years with spastic-type CP and Gross Motor Function Classification System (GMFCS) levels I-II will be included. Participants will be randomly assigned into two groups:

Group 1: A cast will be applied for 3 weeks postoperatively, followed by 24-hour AFO use for 3 weeks, and thereafter night-time use only. A rehabilitation program will be initiated for 12 weeks postoperatively, twice per week.

Group 2: AFO will be used 24 hours a day for 6 weeks postoperatively, followed by night-time use only. Early postoperative rehabilitation will be provided twice per week for 12 weeks.

Assessments will be conducted preoperatively and at postoperative months 3, 6, and 12. The Gross Motor Function Measure-88 (GMFM-88) and the Edinburgh Visual Gait Score will be used as measurement tools.

Gastrotenotomy is a commonly preferred surgical technique in children with spastic CP; however, there is no consensus regarding the optimal duration of postoperative immobilization or the appropriate timing of mobilization. Early mobilization has been reported to have beneficial effects on muscle-tendon flexibility, joint range of motion, and gait pattern.

The findings of this study are expected to contribute to the evidence-based standardization of rehabilitation protocols following gastrotenotomy, and to provide scientific insight into the safety and effectiveness of early mobilization. The results may support clinicians in developing more functional and time-efficient postoperative rehabilitation programs.

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.
