Randomized Controlled Trial
Cyclization of Motor Cortex Stimulation for Neuropathic Pain: A Prospective, Randomized, Blinded Trial.
Programming guidelines for motor cortex stimulation (MCS) in neuropathic pain requires further investigation. After optimizing voltage as a percentage of motor threshold, we evaluated the effect of cyclizing time of stimulation on pain relief for chronic neuropathic pain. ⋯ In this small cohort, cyclization of MCS settings revealed two distinct subgroups: responders and nonresponders. Responders tolerated stimulation in all settings and 50% stimulation (15 min ON/15 min off) was their subjectively preferred setting. Cyclization in responders will prolong battery life and delay the need for INS replacement and may offer improved pain relief. Building from our previous work, we recommend clinicians consider following the Vancouver MCS programming algorithm presented in this manuscript.

Patients with thoracic neuropathic pain often do not respond to medication and physical therapy. Coblation technology has been demonstrated to have potential for pain management. ⋯ Percutaneous thoracic paravertebral nerve coblation guided by computed tomography is a potential method for the treatment of thoracic neuropathic pain.

Pain with neuropathic characteristics is generally more severe and associated with a lower quality of life compared to nociceptive pain (NcP). Short form of the Douleur Neuropathique en 4 Questions (S-DN4) is one of the most used and reliable screening questionnaires and is reported to have good diagnostic properties. This study was aimed to cross-culturally validate the Hindi version of the S-DN4 in patients with various chronic pain conditions. ⋯ Overall, the Hindi version of the S-DN4 has good internal consistency and test-retest reliability along with good diagnostic accuracy.

Aromatherapy Massage for Neuropathic Pain and Quality of Life in Diabetic Patients.
This study aimed to examine the effects of aromatherapy massage on neuropathic pain severity and quality of life (QoL) in patients suffering from painful diabetic neuropathy. ⋯ Aromatherapy massage is a well-tolerated, feasible, and safe nonpharmacological method that can be readily integrated into clinical settings by nursing staff. The essential oils rosemary, geranium, lavender, eucalyptus, and chamomile can be safely used by nurses in the clinical setting, if applicable. However, training and experience of nurses in aromatherapy massage is critical to achieving positive results.

Chronic pain after spinal cord injury (SCI) is a form of central neuropathic pain that is debilitating and often refractory to current pharmacological treatments. Neurostimulation pain therapies, such as epidural spinal cord stimulation, have only moderate success in reducing SCI pain. The pathogenesis of SCI pain may involve a state of central neuronal hyperexcitability, especially in the spinal cord dorsal horn, that develops after injury. ⋯ Our hypothesis can be readily tested in preclinical models of SCI pain by using a combination of in vivo electrophysiological (neuronal activity) and animal behavioral (pain response) approaches. Since ISMS electrodes stimulate the spinal structures directly, we expect that the effective stimulus intensity and energy consumption can be lower than that for epidural spinal cord stimulation. The proposed hypothesis may provide insights and rationales for developing a novel neurostimulation pain therapy by directly inhibiting the pain generators in the spinal cord, and ISMS may be an alternative strategy to treat SCI pain.
