Clinical Trial
Continuous versus intermittent spinal cord stimulation: an analysis of factors influencing clinical efficacy.
Spinal cord stimulation (SCS) has, for decades, been shown to be successful in a variety of chronic neuropathic pain syndromes. However, there is a paucity of reports in the literature comparing different stimulation patterns. The impact of different stimulation patterns upon outcome remains to be determined, as well as how the latter is influenced by the duration of the post-SCS pain-free interval. ⋯ Our data showed an equal effectiveness of SCS in the intermittent and in the continuous stimulation mode. The duration of the post-SCS pain-free interval may be predictive for the choice of the most effective individual stimulation pattern and deserves further investigation.

Subthalamic nucleus stimulation for attenuation of pain related to Parkinson disease.
The objective of this study was to evaluate the efficacy of chronic subthalamic nucleus (STN) stimulation for alleviating pain related to Parkinson disease (PD). ⋯ This study found that STN stimulation produced significant improvement of overall pain related to PD in patients with advanced PD, and the efficacy continued for at least 1 year. The present results indicate that musculoskeletal pain and dystonic pain responded well to STN stimulation, but patients with back pain (somatic pain) and radicular/peripheral neuropathic pain originating from spinal disease have a potential risk for postoperative deterioration of their pain.

Although gender differences in pain and analgesia are well known, it still remains unclear whether men and women vary in response to multimodal pain treatment. This study was conducted to investigate whether men and women exhibited different outcomes after an intensive multimodal pain treatment program. The daily outpatient program consisted of individual treatment as well as group therapy, with a total amount of therapy of 117.5h per patient. ⋯ Consistently, women (ES .694) improved more in pain-related disabilities in daily life than men (ES .436). These distinctions are not due to differences in pain duration, received medication, psychiatric comorbidities, pain chronicity stage, or application for a disability pension. Therefore, gender differences not only refer to chronic pain prevalence, pain perception, or experimental pain measurement, but also seem to have a clinically relevant impact on the response to pain therapy.
