The Effect of the Movement Imitation Therapy in Preterm (MIT-PB) in Motor Behavior's Quality.

Study Overview
=================
Brief Summary
-----------------
This study aims to assess the effect of a parent-administered intervention program based on MIT-PB in preterm with abnormal general movements during the preterm period. We will describe the short and long-term differences between infants exposed to MIT-PB and infants who follow current standard care.

Detailed Description
-----------------
The quasi-experimental design has been planned to assess the effect of a physiotherapy program carried out in neonatal intensive care and at home during the first months of life. Preterm babies born before 32 weeks gestational age (GA) and/or with less than 1500g showing an abnormal General Movement Assessment (GMA) at 34-36 weeks will be included. Standardized tests will be performed at baseline, at term, 44 weeks post-menstrual age (PMA), 54 weeks PMA, 6 months, and 12 months. A qualitative study has been designed to assess the physiotherapy performance and parents' experience. Two different Hospitals with similar care protocols and sizes will recruit the sample (n=36). The Intervention group (n=18) will be located at Hospital Josep Trueta of Girona and the control group (n=18) will be located at Hospital Parc Taulí of Sabadell (Barcelona).

Design Details

Primary Purpose: Treatment
Allocation: Non-Randomized
Intervention Model: Sequential Assignment
Interventional Model Description: The infants will be pre-stratified according to General Movement Optimality Score (GMOs). The Control group will receive standard care and the Intervention group will begin the therapy at 34-36w. The intervention will be explained and guided by the principal researcher and experienced Pediatric Physical therapist. Parents will conduct the intervention until the 50-52 weeks PMA. General Movement Assessment (GMA) will be performed at term, 44w and 54w PMA. Motor assessment will be carried out at 6 months Corrected Age (CA) and a global assessment at 12 months CA. Those assessments will be performed by independent and blind professionals at their corresponding Hospitals.
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Intervention group<br>The group intervention will receive MIT-PB. | Other: MIT-PB, movement imitation therapy for preterm.<br>* The instant an infant showed CS or PR movements, the therapists (or a therapist and a parent) intervened by gently guiding the infants' limbs so as to maneuver and smoothen their movements, thereby imitating normal GM sequences as closely as possible, adding variability to the movement<br>|
| No Intervention: control group<br>The control group will receive standard care | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The quality of General Movement by General Movements Optimality Score (GMOS) and Motor Optimality Score (MOS). | We will videotape General Movements at 34, 38-40, 44 and 54 weeks PMA. The baseline measure( 34w) will be performed by the main researcher and an independent and experienced certified rater. This rater will be blind regarding infant group. The assessments at 38-40, 44 and 54 weeks will be performed by the independent, blind and certified rater in order to guarantee the study validity. The GMOS global assessment can be Normal (N), Poor Repertoire (PR), Cramped Syncronized (CS) or Chaotic (CH). On the detailed score ,the maximum value is 42. The MOS global assessment can be classified as Fidgety (F), Abnormal Fidgety (AF) or Absent Fidgety (F-). On the detailed score the maximum value is 28. Higher scores in both scales are correlated with better global outcome. | Each participant will be assessed from birth to the 54 weeks PMA. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Motor development by Hammersmith Infant Neurological Scale (HINE). | Infants will assessed at 6 months CA by an independent neuro-pediatrician using the HINE. It is a standardized neurological exam for infants adjusted age 2 to 24 months. The HINE evaluates nerve function, movements, reflexes and reactions, posture, and tone and can help clinicians identify movement disorders including cerebral palsy (CP)The maximum global score is 78. Higher scores indicate better neurological performance. | 6 months CA | 
| Global development by Bayley III | An independent neuropsychologists will assess Global Development by Bayley III at 12 months CA. Bayley-III provides information about whether a child's developmental trajectory in the cognitive domain is proceeding as expected, relative to same-age peers. It also includes a motor score, and fine and gross motor subtest scores. The assessment indicates mild, moderate or severe delay. | 12 months CA |
