Brief Summary

Complex Regional Pain Syndrome (CRPS) is a severe and complex chronic pain condition in children. Many psychosocial factors impact its development and recovery. CRPS has a strong central component, which is reflected by structural and functional changes in the brain. However, the interaction between these cerebral changes and trajectory of recovery has been seldom investigated to date. Furthermore, interactions between cerebral changes and psychosocial factors, which might affect trajectory of recovery, are unknown. The aim of this study is to identify the psychosocial factors and cerebral changes that predict the trajectory of recovery from CRPS. Children between the ages of 10 and 17 years will be enrolled with one of their parents or legal guardians for this study. Three populations will be recruited: patients with CRPS undergoing treatment at the Functional Independence Restoration Program (FIRST), patients with CRPS undergoing treatment at the Pain Management Center and matching healthy controls. Participants will undergo three sessions: the first session will be scheduled immediately before or as soon as possible at the beginning of the patients' treatment; the second session will take place at the end of the patients' treatment; the last session will be scheduled six months post-treatment. The timing of the sessions of the healthy participants will follow a schedule similar to the FIRST patients. Each session will last approximately three hours and include acquisition of psychosocial, psychophysical, and brain imaging data in the child participants, as well as acquisition of psychosocial data in the parent participants.

Outcome Measures

Primary Outcomes (2)

  • changes in pain perception

    changes in ratings of spontaneous pain intensity and unpleasantness assessed on non-numerical visual analog scales, ranging from 'no pain sensation'/'not at all unpleasant' to 'most intense pain sensation imaginable'/'most unpleasant imaginable'

    before treatment, at the end of the treatment (an average of 4 weeks for inpatients and 3 months for outpatients after session 1), and 6-month post treatment for patients; 1 month after session 1 and 6 months after session 2 for healthy participants

  • Changes in functional disability

    Changes in scores on the self-reported Functional Disability Inventory investigates disabilities associated with pain which might impact on everyday functioning of children. It includes 15 questions assessing the children's capacity to perform everyday tasks, such as doing chores, walking, or eating regular meals. Participants evaluate their capacity to perform these tasks on Likert-type scale, ranging from "No Trouble" to "Impossible".

    before treatment, at the end of the treatment (an average of 4 weeks for inpatients and 3 months for outpatients after session 1), and 6-month post treatment for patients; 1 month after session 1 and 6 months after session 2 for healthy participants

Secondary Outcomes (3)

  • Changes in functional Magnetic Resonance Imaging (fMRI) BOLD (Blood Oxygenation Level Dependent) and pCASL (pseudo-Continuous Arterio-Spin Labeling) resting-state and task-related brain signal

    before treatment, at the end of the treatment (an average of 4 weeks for inpatients and 3 months for outpatients after session 1), and 6-month post treatment for patients; 1 month after session 1 and 6 months after session 2 for healthy participants

  • changes in fMRI BOLD and pCASL resting-state functional connectivity

    before treatment, at the end of the treatment (an average of 4 weeks for inpatients and 3 months for outpatients after session 1), and 6-month post treatment for patients; 1 month after session 1 and 6 months after session 2 for healthy participants

  • changes in DTI (Diffusion Tensor Imaging) structural connectivity

    before treatment, at the end of the treatment (an average of 4 weeks for inpatients and 3 months for outpatients after session 1), and 6-month post treatment for patients; 1 month after session 1 and 6 months after session 2 for healthy participants

Study Arms (3)

Inpatients

Observation and measure of trajectory of recovery in CRPS. This group will include children diagnosed with CRPS and undergoing regular therapy at the inpatient FIRST clinic at CCHMC and one of their parents or legal guardian.

Behavioral: observation and measure of trajectory of recovery in CRPS

Outpatients

Observation and measure of trajectory of recovery in CRPS. This group will include children diagnosed with CRPS and undergoing regular therapy at the outpatient Pain Management Center at CCHMC and one of their parents or legal guardian.

Behavioral: observation and measure of trajectory of recovery in CRPS

Healthy Controls

For comparison purposes, healthy controls and one of their parents or legal guardian will be enrolled in this study as well.

Behavioral: observation and measure of trajectory of recovery in CRPS

Interventions

Child participants enrolled in this study will undergo three sessions, which will include psychosocial measures, brain imaging, and quantitative sensory testing. Parent participants will also complete three sessions, which only include psychosocial measures.

Study Population

Participants to this study may be part of one of the following groups: children diagnosed with CRPS undergoing inpatient treatment at the FIRST clinic (CCHMC), children diagnosed with CRPS underdoing outpatient treatment at the pain management clinic (CCHMC or comparable outpatient programs), or healthy children. The investigator's groups will be matched as well as possible for BMI, sex, and age. In addition, one parent will be recruited with each child.

  • Former unsuccessful treatment for CRPS
  • Scheduled for or beginning the usual inpatient treatment for CRPS at the FIRST clinic at CCHMC.
  • Outpatients:

  • Scheduled for or beginning the usual outpatient treatment for CRPS at the pain management clinic
  • Healthy children:
  • \- No diagnosis of chronic pain.
  • Parents:
