Abstract

Aim: To find the effect of multisensory therapy based paediatric Occupational Therapy strategies on children with sensory modulation disorder.

Objectives

  1. To screen sensory modulation disorder (SMD) children by using SMD diagnostic sensory profile-2 scale.
  2. To assess sensory under response (SOR), sensory over response (SOR) and sensory craving (SC) of SMD children.
  3. To compare the sensory and behavioural section between control and experimental participation groups.

Methodology: Totally 30 subjects (15 in experimental group and 15 in control group) of age group of 2 years to 35 months participated in current study.

Results: Significant reduction in social sensory modulation quadrants, with regard to multi-sensory therapy in occupational therapy.

Conclusion: participation in multisensory therapy has significant effect in reducing sensory issues and maladaptive behavioural problems in SMD pupil.

Keywords: Multisensory therapy, Sensory modulation disorder, Paediatric Occupational Therapy, sensory profile.

Background

Multi-Sensory stimulation is used in all stages of expansion, from infants to the elderly. They benefit people with cognitive impairments and developmental disabilities resulting from Autism, Cerebral Palsy, Profound Multiple Disabilities, Developmental Disabilities, Chronic Pain Syndrome, ADHD, SPD (Sensory processing Disorder), Pervasive Developmental Delays, Traumatic Brain Injury, Stroke, Coma, Alzheimers and Dementia Multi-Sensory Environments.

Patients with traumatic brain injury and those with ontological impairments also benefit, as do agitated patients and those in need of pain management. The environment in which the sensory stimuli are given is significant in the therapeutic progression (Slavik and Chew, 1990; Walker, 1991). Millers sensory integration dysfunction was renamed into Sensory processing disorder to integrate the work with other fields such as neuroscience. The use of the term sensory integration often applies to a neurophysiologic cellular process rather than a behavioural response to sensory input as connoted by Ayres. Sensory modulation refers to a multifarious central nervous system process by which neural communication that convey information about the concentration, occurrence extent, intricacy, and novelty of sensory stimuli are adjusted consists of three subtypes: Sensory over-responsivity, Sensory under-responsivity and Sensory craving/seeking. Ayres developed her sensory integration therapy in a sensory room with specific characteristics, included the presence of an Paediatric occupational therapist or occupational therapy professional, in a calm and safe environment, and occupational formats that provided significant sensory opportunities utilizing a diversity of modalities to engage the senses (Ayres, 1971; Ayres 1979 as cited in Parham et al., 2007), such as suspension apparatus, therapy balls, ramps, and mountaineering structures.

In contemporary practice, therapeutic interventions often take place in enthusiastic spaces called Multisensory Environments (MSEs).

Aim: To find the efficacy of individualized use of a multisensory integrative environment on engagement in children with sensory modulation disorder.

Objectives

  1. To screen SMD children by using sensory profile-2 scale.
  2. To assess sensory processing skills of SMD children.
  3. To assess sensory under or over processing and also seeking skills of SMD children.

Methodology

Study Design: The study is done with two group of pre-test and post-test of quasi experimental design (Pre-Post Experimental Study). Experimental group = pre-test (multisensory therapy+ interaction) post-test Control group = pre-test (interaction) post-test.

Sample Size: Total numbers of following samples of 30 subjects have engaged in this study. The subjects were divided into two groups as experimental and control group. The control group consist of 15 subjects, and experimental group consist of 15 subjects.

Sampling Technique: Simple Random sampling technique was adopted.

Study Place: Department of Occupational therapy, Unit of Hamsa rehab for kids, Kauvery hospital, Trichy-620 001.

Duration of Study: Duration of the study is 3 months (June 2023 to Sep-2023).

Selection Criteria: Inclusion Criteria; Participants were children with SMD between age 1year to 2.11 years, Children with Sensory modulation problems, both males and females included the study.

Exclusion Criteria: Age should not be more than 3 years or less than 1 year, Children with neurologic problems, Retts, Asperger syndrome, MD, ADHD and other associated conditions are excluded this study.

Variables of the study: Independent variables-multi sensory therapy, dependant variables sensory issues of SMD.

Hypothesis – Null Hypothesis: There are no significant the effect of occupational therapy spatial play-based management on cooperative behaviour in elementary school-aged children with an autism spectrum disorder.

Alternative Hypothesis: There is significant the effect of occupational therapy spatial play-based management on cooperative behaviour in elementary school-aged children with an autism spectrum disorder.

Measurement Tools/Material Required

The tool used for the study is Toddler sensory profile-2 on sensory processing skills. Measured with SMD.

Procedure: subjects attended six sessions per weekly (one introductory session and five MSIE sessions). Sessions were scheduled at the expediency of parents and were completed in three-month duration. Sessions were conducted at around the 45 min per day in an effort to control for individual differences across time of day. In the first session, the research personnel obtained informed consent from the parents and consent from the subjects. The child participant and parent were oriented to the study procedure (including whats app procedure to schedule sessions and to arrive with their child rested, fed, and toileted or changed, as appropriate). The parents completed the demographics questionnaire and the Toddler Sensory Profile-2 (Winnie Dunn) while the research personnel conducted the SMD Diagnostic Scale (SP-2) with the child participant in an adjacent room. The toddler SP-2 assessment was videotaped using a Panasonic high-definition video recorder with audio capabilities for later offline analysis. A stuffed bear named Lucy was used to demonstrate donning and doffing of the devices during the first session. Upon arrival for the six subsequent MSIE sessions (Activity configurational approach protocol-driven condition and three in the individualized condition), the parents were asked to assist the research personnel in applying the physiological measurement devices when needed. Child participants remained seated on a child-sized chair next to the door while the physiological measurement devices were prepared to activate and stream/record. The kids participant was then led to the MSIE to engage in a 45 min session. Parents had the option to inconspicuously observe the sessions via the two wall-mounted cameras or to accompany the child. Research personnel remained with the participants in the MSIE to ensure their safety and take field notes. Research personnel only interacted with the kids if the participant initiated the interaction. When participants engaged in behaviours that were unsafe or destructive, research personnel redirected them. If unsafe or destructive behaviours persisted after three attempts to redirect, the parent was asked to intervene. If the parent intervention was unsuccessful, the session was terminated. After completion of all MSIE sessions, parents were asked to observe videotaped sessions and count incidents of desired and undesired behaviours (as they defined them). Parents were also asked to complete a reflective questionnaire about their kids experience in the MSIE.
