Comparative Study
Efficacy of kilohertz-frequency and conventional spinal cord stimulation in rat models of different pain conditions.
The aim was to compare the effects of high-frequency spinal cord stimulation (HF-SCS) at subparesthetic intensity with conventional SCS in rat models of different types of pain. In addition, microrecordings of afferent activity in the dorsal columns during both types of SCS were performed to elucidate their mode of action. ⋯ Conventional SCS proved equally effective to HF-SCS in various pain models. As no activity is conveyed rostrally in subparesthetic HF-SCS, we hypothesize that its mechanisms of action are primarily segmental.

Review Multicenter Study
Effectiveness of cervical spinal cord stimulation for the management of chronic pain.
Scientific evidence supports spinal cord stimulation (SCS) as a cost-effective treatment option that, for many disease states, should be employed earlier in the treatment continuum. Reimbursement for SCS in the cervical spine has recently been challenged based on supposed lack of clinical literature. To refute this assumption, we analyzed data from an international registry to support the use of cervical SCS. ⋯ The results suggest that the use of SCS in the cervical spine is a medically effective method of pain management that satisfies and improves the QoL of most patients. The use of SCS can reduce the high cost of direct medical treatment of pain, as well as increasing the productivity of patients, and therefore should be reimbursed in appropriately selected patients.

Randomized Controlled Trial
Occipital nerve stimulation in fibromyalgia: a double-blind placebo-controlled pilot study with a six-month follow-up.
The goal of this study is to evaluate the effectiveness of occipital nerve stimulation (ONS) as a surgical treatment for fibromyalgia in a placebo-controlled design. ⋯ Our data strongly suggest that ONS is beneficial in the treatment of fibromyalgia. The beneficial effects are stable at six months after permanent implantation. Subsensory threshold stimulation is feasible in designing a placebo-controlled trial.
