Abstract: BACKGROUND: Motor cortex stimulation (MCS) is routinely used for the treatment of chronic neuropathic pain but its effect on quality of life remains uncertain. OBEJCTIVE: To systematically review the published literature on MCS and quality of life and report the effects of this therapy in a series of patients prospectively followed in our center. METHODS: The systematic literature review was conducted using the search words ""motor cortex stimulation and pain and neurosurgery"" and ""motor cortex stimulation and pain and quality of life."" Quality of life in our clinical trial was investigated in a series of 10 patients with chronic neuropathic pain prospectively followed for 12 mo after MCS. RESULTS: Two hundred eighteen nonreplicated articles were pooled for analysis. Of these, 6 described measures of quality of life in the pre- and postoperative period. In these studies, 64 patients with different clinical conditions associated with neuropathic pain were followed for 6 to 84 mo after MCS surgery. Improvement in quality of life ranged from 35% to 85%. In our clinical series, visual analog scale (VAS), SF-12 physical (PhysCS), and mental scores (MenCS) recorded 12 mo after MCS were improved by 60 +/- 10% (P = .002), 50 +/- 13% (P = .002), and 22 +/- 6% (P = .01), respectively. No significant correlation was found between postoperative improvement in pain and either PhysCS (r = 0.18; P = .6) or MenCS (r = -0.24; P = .5). CONCLUSION: MCS improves quality of life in patients with chronic refractory neuropathic pain. Additional factors other than a simple analgesic effect may contribute to these results.
