Computerised training improves cognitive performance in chronic pain: a participant-blinded randomised...

Area of Science:

• Neuroscience
• Psychology
• Rehabilitation Medicine

Background:

• Chronic pain often impairs cognitive functions, impacting daily life.
• Limited research exists on effective cognitive remediation strategies for chronic pain populations.
• Cognitive deficits in chronic pain include attention, processing speed, and executive functions.

Purpose of the Study:

• To evaluate the efficacy of a computerised cognitive training (CCT) protocol in improving cognitive performance in individuals with chronic pain.
• To assess the impact of CCT on pain intensity, interference, mood, and pain coping mechanisms.
• To explore the role of supervised online delivery and active control conditions.

Main Methods:

• A randomized controlled trial involving 39 adults with chronic pain.
• Participants were assigned to an 8-week CCT program (3 sessions/week) or an active control (documentary videos).
• Weekly video call supervision was provided; primary outcomes included a neurocognitive composite and self-reported cognition.

Main Results:

• The CCT group demonstrated significant improvements in the global neurocognitive composite, particularly in executive functions (attention switching, working memory).
• The active control group showed significant reductions in self-reported pain intensity.
• Both groups reported subjective cognitive improvements and reduced pain catastrophising; no changes were observed in depression, anxiety, self-efficacy, or pain interference.

Conclusions:

• Supervised cognitive training offers preliminary evidence as a viable method to enhance cognitive skills in individuals experiencing chronic pain.
• The study highlights the need for further research to demonstrate transfer of cognitive gains to functional and clinical outcomes.
• Active control engagement suggests that enjoyable activities can improve perceived well-being, and weekly supervision is crucial for adherence.
