The Effect of Vest Type Dynamic Elastomeric Fabric Orthosis (DEFO) on Sitting Balance and Gross Manuel Dexterity in Children With Bilateral Cerebral Palsy: A Feasibility and Randomized, Single-blinded, Pilot Study
The Effect of Vest Type Dynamic Elastomeric Fabric Orthosis (DEFO) on Sitting Balance and Gross Manuel Dexterity in Children With Bilateral Cerebral Palsy: A Feasibility and Randomized, Single-blinded, Pilot Study
To evaluate the effects and feasibility of lycra based compression garment called Stabilizing Pressure Input Orthosis (SPIO) vest on posture and balance during sitting and gross manuel dexterity, parent satisfaction with the garment and to to compare 2 hours vs 6 hours of daily wear time.
Cerebral palsy (CP) is a disorder of development of movement and posture due to non-progressive lesion in fetal or infant brain. Postural control in children with cerebral palsy (CP) is deteriorated due to inappropriate muscle force and lack of sensory integration. The trunk which is found in the centre of the body plays a crucial role in postural control. Research and treatments in CP have focused on extremities rather than trunk control. Both evaluation and treatment of trunk impairment have not been adequately addressed in previously published studies. Improved proximal stability obtained by a better trunk control may lead to improvements in upper extremity function.
Dynamic elastomeric fabric orthosis (DEFO) which are lycra based compression garments provide extra proprioceptive information which enhances body awareness. The more correct proprioceptive input result in the more proper alignment. Vest type dynamic elastomeric fabric orthosis (DEFO) is composed of a front part which is compromised of double-or triple-layer of lycra fabric attached to velcro sensitive neoprene back panel. Thus, it provides adjustable compression around the shoulder, trunk, pelvis, and hips. It is proposed that these orthotic garments provides stabilization of the trunk, shoulder and pelvis girdle and thus improve proximal stability and upper extremity function. Children with sensory deficits and poor muscle strength including children with neuromotor developmental disorders and hypotonia can benefit from the use of vest type dynamic elastomeric fabric orthosis. Severe restricted pulmonary function and refractory cyanosis are absolute contraindications for lycra based orthosis use while having severe reflux symptoms, uncontrolled epilepsy, cardiovascular circulatory disorders and being diagnosed with diabetes are relative contraindications. The adverse events pertaining to the use of these orthoses are difficulty in donning/doffing, toileting problems such as constipation and urinary leakage, decrease in respiratory function, heat and skin discomfort. Due to those unwanted effects, it can be assumed that longer wear time of the orthosis may lower compliance. However, the optimal wear time for vest type dynamic elastomeric fabric orthosis has not been established so far. The reported wear time of suit therapies range from 2 to12 hours a day during 2-12 weeks. The aim of this study was to investigate if the use of a vest type dynamic elastomeric fabric orthosis (DEFO) vest type dynamic elastomeric fabric orthosis is feasible or not and will lead to improvement in sitting balance, sitting as a gross motor function and gross manuel dexterity. The secondary purposes of the present study are to evaluate parent satisfaction with the orthosis and to compare 2 hours vs 6 hours of daily wear time.
