Effectiveness of Vojta Therapy in Motor Development of Preterm Children

May 6, 2013 updated by: Julio Perez-Lopez, Universidad de Murcia

- Justification: Prematurely born children have an increased prevalence of neurodevelopment problems in the first two years. Knowledge regarding the effects of early intervention programs is essential to the follow up of these children and the families.

-Hypothesis: The Vojta Therapy Model showed beneficial effects on motor development outcomes reported by Bayley Sales of Infant Development-Second Edition, in the first 18 months of life on European sample.

Detailed Description

Premature children constitute a heterogeneous group regarding gestational age, determinants and causes of their premature birth, illnesses that occur during the neonatal period and the socio-economic status of the family. These constraints could cause an increase in the risk of development in this group of children, as well as motor abnormalities, when compared to the population of infants born at full term.

Cerebral Palsy (CP), for example, is the most common neurological disorder in this group of children. So many studies showed the association between CP and prematurity. They have pointed out that the probability of premature infants having CP is eight times higher compared to full-term infants.

Apart from CP other minor motor abnormalities are also present in the range of consequences for the preterm children.

Therefore, if the increase is considered in children born prematurely who survive, on account of developments in neonatal care, and that the frequency of appearance of motor sequel described in them remains constant, it is of crucial importance from social, economic and health aspects to implement strategies to improve outcomes for these children. In this regard, the development of physiotherapy treatments aimed at preterm infants is essential from a prevention and intervention point of view.

At the Region of Murcia/Spain, when one child is born preterm is directed from the Neonatal Intensive Care Unit (NICU), where there has already been established a protocol for immediate referral among hospitals to early intervention services, where an interdisciplinary team develops an individualized and comprehensive intervention plan according to the characteristics and conditions of each child and, from the motor point of view, the physiotherapist team will be the one who determines the most appropriate action to be taken.

According Vojta, the basic motor function of human has developed in the course of the first year of life, in a process named Postural and Motor Ontogenesis. The practice of Vojta Therapy (VT) had proved to be effective at the treatment of neuromuscular disturbs. Finally, another researches emphasize the importance of follow up of premature children, due to some problems capable of causing motor disability that might not be detectable in the first moments of life, therefore a longitudinal follow-up is recommended.

Regarding this matter, the general aim of this study is to compare the efficiency of the VT on children motor development opposed to other physiotherapy intervention methods used with premature infants without neurological damage, throughout the first 18 months of life, and taking a group of full term infants as a reference. In order to do so, using a longitudinal research design, referring to four different age-groups where children were followed from the first trimester of life until 18 months, corrected age for premature infants and chronologically for full term infants.

- METHODS: This is a longitudinal research design with four assessment follow up during the first trimester (1), at 6, 12 and 18 months. The children are divided into three groups. An experimental group with premature children treated with Vojta Therapy a control group with premature children treated with other traditional physiotherapy methods and another control group (Group 3) with full term infants presenting no risk or pathology.

  • Instrument: In order to measure motor development, all children in the experimental group and control groups A and B are evaluated with the Bayley-II scales, in particular with the Psychomotor Scale. The Bayley Scales of Infant and Toddler Development (BSID-II) are a set of standardized rating scales, which enable us to assess the mental, psychomotor and behavioral development of children between 1 and 42 months
  • Samples:

The experimental group is composed by preterm children (<37 weeks gestational age), that presented psychomotor delay, but who were not diagnosed with any neurological damage and were receiving VT as a method of physiotherapy treatment, as well as a programme of early intervention including sensory-motor stimulation. This group consists the boys and girls treated at the Early Intervention Centre of Lorca and Aguilas/ Murcia, Spain.

The control group A consists of premature children with similar base characteristics to the experimental group ones who did not receive VT but another method of physiotherapy treatment within a global programme of early intervention that included sensory-motor stimulation. These children are treated and monitored by the Early Intervention Service from the Board of Education of the Region of Murcia (Spain).

The control group B is formed by full term infants, without illnesses or risks. Seventy two boys and girls figured in this group. All children were treated and monitored by the Prevention, Promotion of Early Childhood Development and Early Intervention Service at the University of Murcia (Spain). All parents must sign a consent form authorizing the participation of their children in this project.

- Interventions: Children in the experimental group or Vojta group, receive two weekly sessions of sensory-motor stimulation and two weekly sessions of Vojta Physiotherapy. Sensory motor stimulation and Vojta physiotherapy sessions last 50 minutes each. A guidance programme is also given to parents to carry out at home to promote the overall development of the child and teach the necessary Vojta Method exercises, these are to be performed four times a day for 20 minutes.

Children in control group A or Non-Vojta group, receive two weekly sessions of sensory-motor stimulation and two weekly sessions of physiotherapy with a different methodology to Vojta. Duration of sessions is the same as in the experimental group, of 50 minutes. A guidance programme is also given to parents to carry out at home to promote the overall development of the child and recommendations are provided regarding postural and motor skills that every child needed to ensure proper handling at home.

Children in control group B or the full term infant group receive no intervention of any type but parents are given pointers to promote development at home.

Interventions regarding sensory-motor stimulation in the Early Intervention Centre and guidelines for full term children are carried out by psychologists and specialists in Early Intervention.

Vojta Physiotherapy interventions are performed by expert physiotherapists trained in the method by Vojta Association International.

ANALYSIS OF THE RESULTS All data are analyzed using the computerized statistical package SPSS 15.0 for Windows.

In order to verify our objective, the efficiency of the Vojta Method in motor development of preterm children in the first 18 months of life compared to other physiotherapy methods and using a full term infant group as a reference, mixed 2-factor ANOVA (3x4) with an inter-subject factor (type of sample) with three levels (Vojta, Non-Vojta and Full Term) and one intra-subject factor of repeated assessment (motor development) with 4 measurement times (first trimester, 6, 12 and 18 months) will be used.
