Study Overview

Objective. To determine the effectiveness of a person-centered intervention (comprising personalized and cocreated treatment plans to promote physical activity) for individuals with chronic widespread pain when delivered with digital eHealth support compared with standard telephone follow-up.

Design. Single-blinded multicenter randomized controlled trial.

Settings and participants. Participants with chronic widespread pain (CWP) who had participated in a pain management program from 2010–16 at 5 primary health care rehabilitation centers in 5 cities or towns in the western part of Sweden were invited to join the study between March 2018 and April 2019 via letter providing information about the intervention. The letter was followed by a phone call 1-2 weeks later to screen for inclusion and exclusion criteria and interest in participating. Additional participants were invited to participate via a newspaper advertisement in 1 of the 5 cities.

Inclusion criteria were Swedish-speaking persons aged 20–65 years with CWP (defined as having pain in both sides of the body, pain above and below the waist, and axial pain for at least 3 months). Exclusion criteria included having other severe somatic or psychiatric disorders, dominating causes of pain other than CWP, or other severe disease interfering with the ability to be physically active, pregnancy, not having access to a smartphone or a computer, inability to speak or understand Swedish, ongoing physiotherapy treatment, and already exercising regularly. Of 716 people initially assessed for eligibility, 425 completed telephone screening, and 139 were randomized (using block randomization) to either the intervention arm (n = 69) or the active control arm (n = 70). Due to the nature of the intervention, it was not possible to blind the participants or the physiotherapist to group allocation. All participants provided written informed consent.

The 2 groups underwent the same first individual meeting with a physiotherapist to cocreate a health plan with physical activities, and, if needed, stress management, based on each participant’s individual preferences, obstacles, goals, and resources. The difference between the groups was the type of follow-up support. Participants in the intervention group had 1 follow-up meeting with the physiotherapist a week after the initial meeting (to review and adjust the health plan as needed) and thereafter were supported through a digital e-health platform (accessed via the participant’s smartphone or computer) during the 6-month follow-up period. Participants were encouraged to access the platform once a week to answer questions regarding their health, and the extent to which they had been able to manage their health plan during the previous week. In addition, the participant and physiotherapist could communicate via the platform as needed. Participants in the active control group had 1 follow-up phone call with the physiotherapist 1 month after the initial meeting (similarly to review and adjust the health plan as needed), and no further contact or support from the physiotherapist during the 6-month follow-up period.

Measures and analysis. The primary outcome measure was pain intensity during the previous week assessed with a 0–100 subscale from the Fibromyalgia Impact Questionnaire (FIQ-pain). Secondary outcome measures included overall health status (via FIQ-total with 10 subscales), global fatigue (via FIQ-fatigue subscale), multidimensional fatigue (via Multidimensional Fatigue Inventory, a 20-item questionnaire rated on a 1-5 Likert scale), clinical manifestations of stress (via Stress and Crisis Inventory, a 35-item questionnaire rated on a 0-4 Likert scale), self-efficacy (via General Self-Efficacy Scale, a 10-item questionnaire rated on a 1-4 Likert scale), health-related quality of life (via Short Form 36, specifically the Physical Component Summary composite score), leisure-time physical activity (via Leisure Time Physical Activity Instrument), and physical function (via 1-min chair-stand test). Additional demographic data on age, pain localization, pharmacological treatment, tobacco use, country of birth, level of education, family status, economic status, work status, sick-leave, and disability pension were collected via a questionnaire.

Between-group differences for changes in outcomes from baseline to 6-month follow-up were calculated using the Mann–Whitney U test for continuous data, and Pearson’s χ2 or Fisher’s exact test for categorical data. Significance level was set at 5% with no adjustment for multiple comparisons. All analyses were made according to intention-to-treat by originally assigned group; missing cases were not included in the analysis.
