About

Spastic wrist flexion deformity is a very common problem in children with CP. Although serial casting (SC) is one of the commonly used interventions in addition to botulinum toxin A (BoNT-A) injections and physical therapy for spastic deformities of lower extremity of children with CP, there is limited data on SC in the upper extremity.

In this prospective, randomized, controlled clinical trial in order to overcome the issues with patient compliance, side effects and combined treatment options an intermittent SC model was developed. The objective of this study was to show the effects of intermittent SC when combined with occupational therapy (OT) and BoNT-A injections on spasticity, and passive range of motion (pROM) of children with CP having spastic wrist flexion deformity.

Full description

Spasticity is not only the most common motor disorder but also the main cause of slowly developing secondary problems like contractures in children with cerebral palsy (CP). Spastic wrist flexion deformity is a very common problem in children with CP and can be primarily due to spasticity of the palmar muscle complex, can be exacerbated by the weakness of the antagonist dorsiflexor muscles and can involve soft tissue and joint contractures. Although serial casting (SC) is one of the commonly used interventions in addition to botulinum toxin A (BoNT-A) injections and physical therapy for spastic deformities of lower extremity of children with CP, there is limited data on SC in the upper extremity. Skin irritation or breakdown, painful epizodes, oedema, tendonitis, weakness, stiffness are some of the side effects reported after SC. Moreover casting especially when prolonged might complicate activities of daily living for instance by increasing the risk of falls or causing problems in bathing. Recent evidence from literature favors early, goal oriented, activity based, intensive, repetitive motor trainings in enriched environments to optimize neuroplasticity in children with CP. Prolonged serial casting might also interfere with these activity based, intensive rehabilitation options for upper extremity.

In this prospective, randomized, controlled clinical trial in order to overcome the issues with patient compliance, side effects and combined treatment options an intermittent SC model was developed. The objective of this study was to show the effects of intermittent SC when combined with occupational therapy (OT) and BoNT-A injections on spasticity, and passive range of motion (pROM) of children with CP having spastic wrist flexion deformity.
