Comparing Two Protocols to Improve Reflex Integration and Functional Performance

Study Overview
=================
Brief Summary
-----------------
The goal of this quantitative experimental study is to compare two occupational therapy interventions intended to improve functional skills. The main questions it aims to answer are: Question 1: Do preschool children who participate in occupational therapy intervention designed to promote integration of the TLR reflex in conjunction with fine and gross motor intervention demonstrate improved integration of the TLR reflex in clinical assessment, compared to children who participate in fine and gross motor intervention only for an equal amount of time? Question 2: Do preschool children who participate in occupational therapy intervention designed to promote integration of the TLR reflex in conjunction with fine and gross motor intervention demonstrate improved integration of the TLR reflex in clinical assessment, compared to children who participate in fine and gross motor intervention only for an equal amount of time? Participants will participate in either a therapy program consisting of either fine and gross motor treatment in conjunction with reflex integration treatment, or fine and gross motor treatment only. If there is a comparison group: Researchers will compare the group recieving reflex integration in conjunction with fine and gross motor treatment and the fine and gross motor only group to see if one is more effective at integrating the reflex and/or improving functional skills.

Detailed Description
-----------------
Pre-intervention, INPP screening for TLR will be administered to determine eligibility for the study and baseline of reflex persistence. the Peabody Developmental Motor Scales 2nd Edition (PDMS2) stationary and visual motor integration sections will be administered to assess fine and gross motor skills. Stratified random sampling will be used to create two parallel groups. Both the INPP and PDMS2 will be administered and scored by a masked examiner who is licensed to practice occupational therapy. For 6 weeks, one group will receive 20 minutes standard occupational therapy intervention while the second group will receive 10 minutes of standard occupational therapy intervention and 10 minutes of TLR integration protocol (Move Play Thrive Program). 20 minutes per week is standard treatment time for preschool occupational therapy sessions in Aberdeen School District. Intervention will be provided by the PI, Healey Miller. Post-intervention, the Peabody Developmental Motor Scales 2nd Edition (PDMS2) stationary and visual motor integration sections will be re-administered to assess fine and gross motor skills and the INPP screening for TLR will be re-administered to assess for retained TLR reflex. Both the INPP and PDMS2 will be administered and scored by a masked examiner who is licensed to practice occupational therapy. Data will be reviewed to determine if the progress made between groups, in regard to motor skills and reflex integration, is statistically significant. Data will be reviewed to compare progress made in each group in fine/gross motor skills and reflex integration, and to determine if changes made are statistically significant.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: participants will be assigned to one of two groups. Each group will recieve the same minutes of treatment however one group will include reflex integration and one will include fine and gross motor intervention (standard OT treatment) only.
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Reflex integration + fine and gross motor treatment<br>For 20 minutes per week for 8 weeks, this group will recieve 10 minutes of fine and gross motor treatment and 10 minutes of reflex integration exercises from the Move Play Thrive program. | Other: Reflex integration + fine and gross motor treatment<br>* occupational therapy intervention involving general fine and gross motor activities as well as targeted reflex integration exercises<br>* Other names: Move, Play, Thrive reflex integration exercises;|
| Active Comparator: Fine and gross motor treatment only<br>For 20 minutes per week for 8 weeks, this group will recieve 20 minutes of standard occupational therapy treatment consisting of fine and gross motor intervention. | Other: Fine and gross motor treatment only<br>* occupational therapy intervention involving general fine and gross motor activities<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline functional skills at 8 weeks | functional skills as measured by the Peabody Developmental Motor Scales Stationary and Visual Motor Integration sections. This standardized test scoring can be converted into z-scores for data comparison. | week 0 and week 8 | 
| Change from baseline TLR inegration at 9 weeks | integration of the tonic labyrinthine reflex as measured by the INPP measure for retained primitive reflexes. INPP scale 0-4, 0 being no reflex retained and 4 being severe reflex retention | week 0 and week 8 |
