Comparison of the efficacy of two interventions in ameliorating abdominal thickness and sitting function in children with diplegia.

Objective/Background: The abdominal muscles are extremely important in stabilizing the trunk and maximizing postural stability. The presence of apparent stiffness in children with spastic diplegia is associated with unsteadiness, impaired walking, and pelvic malrotation. The aim of this study was to compare the efficacy of hippotherapy and whole-body vibration in ameliorating abdominal muscle thickness and sitting function in children with diplegia.

Methods: A total of 60 children with spastic diplegia were selected from the Faculty of Physical Therapy's outpatient clinic, Cairo University, and randomly allocated into two groups. Group A received conventional physical therapy for 1 h in addition to whole-body vibration, whereas group B received hippotherapy for 40 min. The same designed physical therapy program was administered for 12 weeks, three times per week, in both groups. Ultrasonography was used to measure abdominal thickness, and Gross Motor Function Measurement-88 was used to measure functional ability.

Results: A significant improvement in abdominal muscle thickness and sitting function ( p  < 0.05) was observed in both groups, and greater improvements were observed in group B.

Conclusion: Whole-body vibration and hippotherapy training may be recommended to facilitate sitting function and ameliorate abdominal thickness in children with diplegia. Hippotherapy is more effective than whole-body vibration in improving sitting function and abdominal muscle thickness.
