Immersive Virtual Reality Therapy with Myoelectric Control for Treatment-resistant Phantom Limb Pain: Case Report

Conclusions: Currently available immersive virtual reality technology with myolectric and motion tracking control may represent a possible therapy option for treatment-resistant phantom limb pain. Keywords: virtual reality, phantom limb pain, rehabilitation, amputation, therapy, pain Innov Clin Neurosci. 2017;14(7–8):3–7 Phantom limb pain (PLP), the sensation of pain in an absent limb, is a frequent complication after amputation, with reported prevalence rates ranging from 40 to 85 percent.1,2 While the exact mechanism of PLP remains to be elucidated, peripheral and central neural factors are thought to contribute to this phenomenon.2 One current theory is that maladaptive neuroplastic changes in the sensory and motor cortices are associated with development of PLP.3 While no longer thought to be the sole cause of PLP, emotional factors also play a role in this condition. Significant psychological comorbidities have been noted among those with PLP, including anxiety (66%) and depression (41%).4 PLP is also a risk factor for developing depression in individuals with limb loss, with prevalence of significant depressive symptoms in this population close to 30 percent in a large cross-sectional study.5 Other risk factors for developing PLP include pre-existent pain, residual limb pain, and female gender.8 The prognosis for PLP is highly variable, with some patients having complete resolution of symptoms acutely, and others reporting chronic pain lasting for years.2 A ...

We describe the most highly recommended generic and disease-specific PRO tools in SCD and discuss the challenges of incorporating them in clinical practice. EXPERT OPINION: PRO measures are essential to incorporate into SCD clinical trials either as primary or secondary outcomes. The use of PRO measures in SCD facilitates a patient-centered approach, which is likely to lead to improved outcomes. Significant challenges remain in adapting PRO tools to routine clinical use and in developing countries. PMID: 33034214 [PubMed - as supplied by publisher]

Currently in fellowship doing bread/butter procedures (MBB, epidurals, PNB, few SCS/PNS trials, etc.) and just interviewed at a private practice spot where they do a lot of procedures that I will have not done any training in prior to graduating (e.g. IT pump, SI fusion, Vertiflex, Kypho, MILD, Discectomy, lots of SCS/PNS trials etc) and significant amount of "OR pain procedures" at a very busy practice seeing 30-40 pts/day - how many of you are commonly performing these procedures and are... private practice concern

Conclusion Visual estimation had excellent intra-rater reliability in the assessment of neck active rotation and head tilt on infants with congenital muscular torticollis. Visual estimation had acceptable inter-rater reliability in the assessment of neck active rotation but not of head tilt. There was a wide variation in reliability with no correlation between reliability and clinical experience. Assessment tools for head tilt that are more psychometrically robust should be developed.What is Known:• A thorough assessment of infants presenting with torticollis is essential, using assessment tools with robust psychometr...

In this study, an attempt to oxidise the surface of a commercial activated carbon to improve its adsorption capacity for sevoflurane was conducted using 6 mol/L nitric acid, 2 mol/L ammonium persulfate, and 30 wt per cent (wt%) of hydrogen peroxide (H2O2). The adsorption tests at fixed conditions (bed depth: 10 cm, inlet concentration: 528 mg/L, and flow rate: 3 L/min) revealed that H2O2 oxidation gave desirable sevoflurane adsorption (0.510 ± 0.005 mg/m2). A parametric study was conducted with H2O2 to investigate the effect of oxidation conditions to the changes in surfa...
