Sensory Modulation to reduce restrictive practice Part 2: Policy Context

Currently, NDIS providers are struggling to reduce the use of restrictive practices in service delivery. A report by the NDIS Quality and Safeguards Commission showed that there were more than a one million incidents of unauthorised restraints in 2020 – 2021, a 240% increase from the previous 12 months. The restraints included use of sedation, strapping down a person or depriving them of their personal belongings. (Henriques-Gomes, 2021 report of NDIS quality and safeguards commission)

As described in Part 1 of this blog series, Sensory Modulation is an intervention shown to be effective for reducing restrictive practice. Sensory Modulation can be defined as “using your senses to change the way you feel” (O’ Sullivan, Fitzgibbon 2017). Sensory Modulation interventions involve:

  • identifying problematic, or overwhelming sensory stimuli and developing strategies to reduce the input or promote self-regulation, with the goal of supporting the individual to continue to be able to engage in occupations.

  • Identifying calming and soothing sensory strategies to prevent the use of and/or be an alternatives to restrictive practices.

Acute Care Team Legend Rachel Woolcock using cooling down sensory modulation options.

Recently I met with one of the most experienced and skilled Mental Health Clinical Nurses in Queensland – Rachel Woolcock. Rachel has over 20 years’ experience with Mental Health including acute care and homeless health. Rachel has undertaken Sensory Modulation Brisbane training and applies Sensory Modulation strategies regularly when working with very distressed or agitated clients. Rachel identifies that one of the most beneficial techniques for this client group has been cooling down with the dive reflex response. In her experience, Rachel has found that it is important to acknowledge that the technique sounds 'unusual' or 'a bit funny' but continues to encourage people to try it, with positive outcomes!

Factors Influencing Occupational Performance

Occupational Therapists have a lead role working with individuals in the area of occupational performance. Occupational performance refers to how a person engages in meaningful and valued activities in their life and can include self care, daily living skills, community living skills, work, leisure and many more.

An Occupational Therapist who is assisting a person with their occupational performance will identify strengths, barriers, supports, problems and solutions to participating in occupational performance. This process often involves an observation of the person undertaking a or a select number of tasks, as well as completion of checklists and standardised assessments. From here, the OT will then identify possible interventions, with regard to the person (P), the environment (E) and the task/occupation (O), aimed to improve or assist their ability to actively engage in the activity, thus enhancing their occupational performance.

Intense Sensations to Manage Muscle Cramps and Dissociation

Sensory Modulation Brisbane often discusses the effectiveness of sensory input as a pain competitor, to more effectively manage pain and improve functioning. For example, using temperature, deep pressure or intense scent. It is understood that the application of sensory input interferes with the transmission of pain signals, thus dialling down the intensity.

Sensory Preferences in the Work Environment (Office)

Working from home/ changes to work locations has been one of the many challenges facing individuals during COVID-19. Some people have absolutely loved this change, while others cannot wait to return to the office environment. Are these differences all to do with personality traits? Or the trend towards open office spaces? Occupational therapists would suggest that it may also reflect our diverse sensory preferences.

Weighted Blankets: Need for more evidence but definitely not no evidence

Weighted blankets are a popular Christmas present this year and have also been described by Time Magazine as one of the best inventions of 2018 (Source: Choice Magazine.) Gravity weighted blankets have sold over $18 US million dollars worth of weighted blankets yet many experts say that there is no evidence that they work. .

I must admit I am getting a little tired of ‘experts’ being interviewed who state that there is no evidence for weighed blankets. I wonder if they do a recent google search or if they are going on something that they read years ago when the research trials were just beginning.

It would be more accurate to describe that there is strong evidence in some areas and limited evidence in other areas. In research groups, strong and limited evidence is described according to levels of evidence. This table describes the categories of level of evidence.

Sensory Triggers Screen- Acute Medical Environment

Sensory Modulation and the Hospital Environment

Hospital admissions can be an extremely overwhelming experience, no matter the reason or duration of the stay. A significant contributing factor to this is the experience of sensory triggers, often at heightened levels and unique to the hospital setting. This overstimulation of the senses is further compounded by the person’s difficulty in modulating the environmental input to suit their individual sensory needs due to illness or injuring, having cognitive or mental health issues, and simply not having the ability to control the environment they are inhabiting.

Teachers: Keeping calm in the classroom

Sometimes it sounds like Mission Impossible to keep calm in a classroom with dozens of noisy kids present. In this blog I will outline some quick strategies using Sensory Modulation in a primary school classroom.

Sensory Modulation is changing how you feel through using your senses.

  1. Take a movement break in the classrrom

    Both you and the children in the class can Jump up and down, start jumps, jog on the spot.

    Just a couple of minutes of intense exercise can provide a relaxation response through activating the parasympathetic nervous system. This technique has worked for some people for a panic attack. *

  2. Seating

    Try sitting on a wedge cushion or wobble stool and use this to make small movements. Sit up, drop your shoulders and take some long breaths out. Push your feet into the floor for grounding.

  3. Icy Water

    Icy water held over your eyes can invoke the dive reflex and provide calming. Can you take a quick trip to the bathroom and use this technique there? Have a zip lock bag ready, fill it one third with icy water and hold your breath. This technique should not be used if you have a heart condition or anorexia nervosa as it changes the heart rate quickly.

    Some teachers are using this strategy with the whole class ad keep the ziplock bags in the fridge for students or teachers to use.

  4. Weighted Items

    Use several wheat packs or a weighted cushion on your lap (up to 10 per cent of your body weight) This can be a very calming sensation

  5. Low stimulation time

    Have a low stimulation and calming time for the entire class. Dim the lights, put on some white noise or calming music and use this time to relax and let go of tension.

I hope that you can try these techniques and try one that will work for you. It can be very useful for children to see someone modelling how to stay calm. So if you have a technique that you can try, talk to the kids about t it and see if they would like to try it to.

If you would like to learn more about these techniques, you could purchase the “Sensory Modulation Resource Manual’ or attend the Brisbane based “Sensory Modulation for Teacher Self Care workshop ‘ in September 2019.

How do you do Sensory Modulation on an Impatient Mental Health Unit without a Sensory Room?

A Sensory Room is a dedicated room with an array of sensory items and strategies for people to trial and use to support their development of self-management skills and to change their moods through Sensory Modulation*. Sensory rooms have been found to be useful in many mental health units by those who use them. (Champagne, 2011).  

Often people express that they would like to use Sensory Modulation, but that their organisation is unable to fund a Sensory Room or find the space to put one. The good news is that is possible to use Sensory Modulation on an inpatient ward or emergency department without a Sensory Room through the use of low cost or existing sensory items or considering the environment.

Using your senses for self-care

Self-care is increasingly identified as a foundation for physical and mental health and wellbeing. It can be explained as self-directed activities a person engages in with the goal of moving towards a more optimal level of health. Self-care activities involve general daily living tasks (such as healthy eating, getting enough sleep and regular exercise) and can incorporate additional self-initiated activities that may be viewed as relaxing (yoga, meditation), pampering (massage, facial, movie) or a social outlet (date night, catching up with friends).
