Chronic pain has a substantial negative impact on work-related outcomes, which underlines the importance of interventions to reduce the burden. Spinal cord stimulation (SCS) efficiently relieves pain in specific chronic pain syndromes and is recommended for treating failed back surgery syndrome (FBSS) or post-surgical chronic back pain that is refractory to other treatments. To examine the impact of SCS in patients with FBSS on the return to work (RTW), we determined the RTW rate and the factors positively associated with the RTW. ⋯ Our protocol for SCS for patients with FBSS, including a strict selection of patients and a multidisciplinary approach, led to good results, especially for the RTW. RTW should be a therapeutic goal, directly affecting indirect costs related to FBSS.

Our meta-analysis aimed to compare the analgesic effectiveness of ultrasound-guided preoperative erector spinae plane block (ESPB) versus paravertebral nerve block (PVB) in breast surgery. ⋯ Both ultrasound-guided preoperative ESPB and PVB showed comparable analgesic effects in patients undergoing breast surgery. However, with a significantly shorter procedure time and higher block success rate, our findings suggest that ESPB may be a simple alternative to PVB in breast surgery.

Identifying EEG brain markers might yield better mechanistic insights into how chronic pain develops and could be treated. An existing longitudinal EEG study gave us the opportunity to determine whether the development of pain is accompanied by less alpha power-ie, a "relaxed" brain state-and vice versa. ⋯ Transitions in pain states are linked to a change in baseline EEG activity. Future research is needed to replicate these results in a larger study sample and in targeted clinical populations. Furthermore, these results might be beneficial in optimizing neurofeedback algorithms for the treatment of chronic pain.
