Fibromyalgia Symptom Reduction by Online Behavioral Self-monitoring, Longitudinal Single Subject Analysis and Automated Delivery of Individualized Guidance.
Collinge, William, Yarnold, Paul, Soltysik, Robert · North American journal of medical sciences · 2013 · DOI
Quick Summary
This study tested a website tool called SMARTLog that helps people with fibromyalgia track their symptoms and receive personalized feedback. Patients who used the tool several times a week for a few months reported improvements in pain, fatigue, memory, mood, and sleep. The more consistently people used the tool, the greater their symptom improvements tended to be.
Why It Matters
Digital self-monitoring tools may offer accessible, low-cost symptom management strategies for ME/CFS patients, who often have limited access to specialized care. Understanding how behavioral self-monitoring and personalized feedback can reduce symptom burden may inform development of scalable remote interventions for post-viral and chronic fatigue conditions.
Observed Findings
- Moderate use of SMARTLog (3 times weekly for 3 months) was associated with clinically significant improvements in pain, memory, gastrointestinal problems, depression, fatigue, and concentration.
- Heavy use of SMARTLog (4.5 times weekly for 5 months) produced additional improvements in stiffness and sleep difficulties.
- Individualized classification trees could be derived for each user linking specific behaviors to symptom levels over time.
- Greater frequency of tool use was correlated with broader symptom improvements.
Inferred Conclusions
- Web-based behavioral self-monitoring with personalized, data-driven feedback can enable fibromyalgia patients to achieve clinically meaningful symptom reduction.
- Dose-response relationship exists between frequency of self-monitoring engagement and breadth of symptom improvement.
- Individualized, algorithm-generated behavioral feedback may help patients identify personal symptom triggers and effective management strategies.
Remaining Questions
- How do improvements with SMARTLog compare to control conditions such as standard care, placebo web interfaces, or symptom tracking without feedback?
- Do symptom improvements persist after discontinuation of the tool, or do they require ongoing monitoring?
What This Study Does Not Prove
This study does not prove that the SMARTLog tool itself causes symptom improvement—improvements could result from increased self-awareness, attention, placebo effects, or natural fluctuations in fibromyalgia. The lack of a control group makes it impossible to determine whether outcomes exceed what occurs without the intervention. Results may not generalize to ME/CFS patients, as fibromyalgia and ME/CFS have distinct pathophysiological mechanisms.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
