myoActivation® for Chronic Pain in a Marginalized Population

Completed

• Conditions: Pain, Chronic; Widespread Chronic Pain
• Interventions: Other: myoActivation; Other: Physiotherapy

• Registration Number: NCT04261959
• Lead Sponsor: University of British Columbia

Brief Summary

Marginalized populations are at increased risk of chronic pain, trauma and use of street drugs to manage this suffering, with the associated risk of overdoses. Non-pharmacological options to manage chronic pain are difficult for this population to access. myoActivation® is an innovative structured assessment and therapeutic approach. This study will be conducted in the Vancouver Community Primary Care Chronic Pain Service and will include myoActivation and physiotherapy. The study will include sixty patients who seek care on a Tuesday, the only day that myoActivation is offered, and will examine the impact of these treatments on pain outcomes, function and quality of life.

Detailed Description

Purpose: This study will evaluate the inclusion of myoActivation in primary care for marginalized persons with concurrent opioid use disorder (OUD), chronic pain and trauma history. The research aims to investigate whether myoActivation improves pain intensity, quality of life, physical function, and reduces the need for prescribed analgesics (including opioids) and reported illicit drug use.

Hypothesis: The investigators hypothesize that patients with chronic pain who are treated with myoActivation will experience a reduction in pain and improvement in function and quality of life as shown by a 30% reduction on the PEG score (Pain intensity, interference with Enjoyment of life, interference with General activity) at 4, 12 and 24 weeks.

Justification: Chronic pain is typically treated by prescription of analgesic medications, including opioids. However, many patients who have overdoses are using opioids and other substances (including street drugs, alcohol, and marijuana) to manage chronic pain. There are an inadequate number of effective non-pharmacological options to manage chronic pain and wait lists for local Vancouver chronic pain clinics are as long as a year. Other treatment modalities offered by the Vancouver Community pain service include physiotherapy, counselling and group therapy.

Objectives: The investigators aim to demonstrate an improvement in pain intensity, quality of life, and physical function as the primary outcomes. Secondary objectives include reduced need for analgesic medications (including opioids) and illicit drug use.

Research Design: This study is a prospective, mixed method design, including 1:1 semi-structured patient interviews. It is an observational study: patients will NOT be allocated to treatment on the basis of randomization or their enrollment in the study, i.e. participants will receive routine clinical care, based on the services offered by the clinical team at the pain clinic, and this will not change with their participation in the study.

The study will involve recruitment of sixty patients who attend the pain service on Tuesdays, when myoActivation and physiotherapy are offered, and who consent to being contacted for follow up data collection and interviews. The aim is to recruit 20 patients receiving myoActivation, 20 patients receiving physiotherapy and 20 patients receiving both treatments.At the time of recruitment, the subset of patients who have concurrent opioid use disorder, other addictions and / or trauma will not be known.

Data collection includes:

* a baseline score of the patients' pain experience using the validated questionnaires PEG, Pain Catastrophizing Scale (PCS) and Pain Self-Efficacy Questionnaire (PSEQ).

* information on baseline mental health conditions - OUD, Trauma, Anxiety, Depression, Axis 1

* PEG, PCS, PSEQ scores as well as the patient reported use of street drugs and pain medications will be collected at 4, 12, 24 weeks using a study designed questionnaire

* a semi-structured 1:1 patient interview at 12-24 weeks will assess opioid/drug use, as well as questions related to changes to housing, finances and overall health; this will be conducted with 10 randomly selected participants who have received myoActivation.

Statistical Analysis: To allow for correlation of repeated data points on the same patient as well as the anticipated variability in the number of data points for each patient, a linear mixed-effects model will be used to analyze the quantitative data, including PEG score and self-reported opioid use. A PEG score decrease of 30% will be taken to indicate an improved pain experience. The PCS and PSEQ scores will be used to interpret the severity and change of an individual's pain score.

The patient interview responses will be collated for common themes and used to augment the quantitative data outcomes. Interviews will be recorded and transcribed. Thematic analysis will be used to identify key words and phrases, list noted benefits of the service, potential problems raised and any preferences expressed by participants with respect to the way the treatment is administered.

Name	Time	Method
PEG score wk 4	4 weeks	PEG is a validated self-report measure of (1) Pain intensity, (2) interference with Enjoyment of life, (3) interference with General activity. Each of the 3 dimensions is scored on a 0-10 scale. Total score is the average (mean) of the 3 values, minimum 0, maximum 10, lower score indicates a better outcome.
