Multidisciplinary Digital Therapeutics of Chronic Lower Back Pain Versus Usual Care

EverEx Inc.46 enrolled

Overview

This randomized controlled pilot study will be evaluating an app, MORT-LBP app (ETH-02K), owned by EverEx, Inc., to examine safety and efficacy in individuals with chronic lower back pain.

This randomized controlled pilot study will enroll 46 participants, where half will be randomly assigned to the app, MORT-LBP (n = 23), and half will be assigned to treatment as usual (TAU) (n = 23), to examine safety and efficacy in individuals with chronic lower back pain. All subjects will be followed up in the study for a total of 12 weeks, 8-week courses of treatment with additional 4-week observation. The app provides multidisciplinary rehabilitation treatment, a combination of graded exercise therapy and cognitive behavioural therapy for patients with chronic lower back pain.

Outcomes

Primary Outcomes

Usual pain severity in the past week assessed by the Numeric Rating Scale (NRS)

The primary outcome being measure is differences in usual pain severity in the past week between groups after the intervention. NRS score was measured from 0 (no pain) to 10 (worst pain imaginable).

Time frame: 8 weeks

Worst pain severity in the past week assessed by the Numeric Rating Scale (NRS)

The primary outcome being measure is differences in worst pain severity in the past week between groups after the intervention. NRS score was measured from 0 (no pain) to 10 (worst pain imaginable).

Time frame: 8 weeks

Functional disability assessed by Oswestry Disability Index (ODI)

The primary outcome being measure is differences in functional disability between groups after the intervention. Oswestry Disability Index (ODI) is a patient reported assessment of chronic lower back pain-specific functional limitations. It has 10 questions, total score ranging from 0 to 50, and ODI is calculated with (total score)/(answered question number \* 5)\*100%. Higher index means worse outcome.

Time frame: 8 weeks

Secondary Outcomes

Ususal pain severity in the past week assessed by Numeric Rating Scale (NRS)

The secondary outcome being measure is differences in usual pain severity in the past week between groups at 4 and 12 weeks. NRS score was measured from 0 (no pain) to 10 (worst pain imaginable).

Time frame: 4, 12 weeks

Worst pain severity in the past week assessed by Numeric Rating Scale (NRS)

The secondary outcome being measure is differences in worst pain severity in the past week between groups at 4 and 12 weeks. NRS score was measured from 0 (no pain) to 10 (worst pain imaginable).

Time frame: 4, 12 weeks

Time frame: 4, 12 weeks

Health-related quality of life assessed by EuroQol five-dimensional (EQ-5D)

The secondary outcome being measure is differences in health-related quality of life between groups at 4, 8 and 12 weeks. It measures five dimensions of health: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression, with three possible answers for each dimension (1=no problem, 2=moderate problem, 3=severe problem). The instrument also includes a visual analogue scale, which is numbered from 0 (the worst health you can imagine) to 100 (the best health you can imagine).

Time frame: 4, 8, 12 weeks

Assessment of mental health symptoms specific to depression as assessed by the Patient Health Questionnaire-9 (PHQ-9)

Differences in mental health symptoms between groups at 8, 12 weeks. The Patient Health Questionnaire-9 (PHQ-9) total score for the nine items ranges from 0 to 27 (higher scores indicating greater severity of depression).

Time frame: 8, 12 weeks

Assessment of catastrophic thinking measured by Pain Catastrophizing Scale (PCS)

Differences in levels of catastrophic thinking between groups at 8, 12 weeks. The Pain Catastrophizing Scale (PCS) is a 13-item scale, with a total range of 0 to 52 (higher scores indicating higher amounts of pain catastrophizing).

Time frame: 8, 12 weeks
