Mechanisms and Outcome-Prognostication for Paresthesia-based and -Free Spinal Cord Stimulation
Neuropathic PainChronic PainSpinal cord stimulation (SCS) relies on stimulation of pain-relieving pathways in the spinal cord to treat chronic neuropathic pain. Traditional paresthesia-based SCS (PB-SCS) relies on providing analgesia through stimulation of spinal cord dorsal columns but it is often associated with attenuation of analgesic benefit and lack of acceptance of paresthesias. Recently introduced three different paresthesia-free (PF-SCS) modes of stimulation aim to overcome limitations of PB-SCS. Several questions regarding PB and PF SCS modes remain unanswered including the mechanisms of therapeutic benefit, criteria for selecting patients likely to benefit, and long-term outcomes. A concerted effort is required to understand and optimize utilization of SCS. This project has the twin goals of using neuroimaging techniques to understand mechanisms that underlies analgesic benefit from PB/PF-SCS modes and to identify criteria for selecting patients based on monitoring of pain and its related domains in patients undergoing SCS trials. Achieving these objectives will increase probability of analgesic benefit while minimizing adverse effects and knowledge gains from this study will be applicable to other therapies for chronic pain conditions.
Effect of Electroacupuncture in Patients Submitted Orthognathic Surgery and Mentoplasty
ParesthesiaEdemaGoals. To evaluate the effect of electroacupuncture on paresthesia and myofunctional changes in patients undergoing bimaxillary orthognathic surgery and mentoplasty. Methodology: this is a controlled, randomized, blinded clinical trial. The sample will consist of 62 individuals in each group (general sample = 124 participants). Therefore, 124 young adults, aged between 18 and 50 years, both sexes, with at least 24 teeth, with Class II or III skeletal malocclusion, diagnosed by cephalometric radiographs, who underwent orthognathic surgery in the period from 1 to 30 days before the start of physical therapy, be available to perform the proposed postoperative treatment for six weeks. Participants will be equally and randomly distributed into two experimental groups: GF (Physiotherapy Group), GFE (Physiotherapy plus Electroacupuncture Group). The variables to be studied will be: socioepidemiological data; sensitivity assessment by the Semmes-Weinstein monofilament test; Edema assessment by the MD Anderson Cancer Center Head and Neck Lymphedema protocol, validated in Portuguese; assessment of mandibular movements using a Western-DC digital caliper; Assessment of masticatory function using the Chewing Quality Assessment Questionnaire. Data will be analyzed descriptively and organized into tables. Subsequently, the normality of continuous variables will be tested by the Kolmogorov-Smirnov test. As the variables are normally distributed, we will use parametric tests such as the paired t test, independent t test, ANOVA and Pearson's correlation. Nonparametric tests such as Wilcoxon paired signed rank test, Mann-Whitney U test, Kruskal Wallis test, Spearman correlation test will be used in case of non-normality of continuous variables. The significance level will be adjusted to 5% in all analyses.
Paresthesia-free Peripheral Nerve Field Stimulation for Trigeminal Neuralgia (FreeST Trial)
Trigeminal NeuralgiaFacial PainStudy type: Prospective, double-blinded, double arm, cross-over, randomized controlled clinical trial. Brief protocol: Postoperative week 0-2 -> Conventional parameters (parameters tested during trial period) Postoperative week 2-6 -> Sham stimulation (2 weeks) and paresthesia-free stimulation (2 weeks) double-blind crossover design Postoperative week 6 - month 12 -> Parameters that patients feel more benefit from
Paresthesia Free Spinal Cord Stimulation (PF-SCS)
SCSChronic PainThe goal is to document efficacy of PF-SCS therapy in a blinded fashion and better understand how SCS therapy works in the clinical setting. Overall the investigators hope to improve patient care and selection of candidates who have the best potential for effective pain relief from an expensive and invasive therapy.
