Virtual and Augmented Reality-based Treatments for Phantom Limb Pain: A Systematic Review.

Objective: To evaluate the literature on the effectiveness of virtual reality (VR)- and augmented reality (AR)-based treatments for phantom limb pain (PLP) in postamputation or brachial plexus avulsion (BPA) populations. Methods: Multiple databases were queried in July 2021 with the keywords "virtual reality," "augmented reality," and "phantom limb pain." Included studies utilized VR or AR to treat PLP with outcome measurement. Two independent reviewers assessed methodological quality using the Physiotherapy Evidence Databsae (PEDro) Scale and the Methodological Index for Nonrandomized Studies (MINORS) scoring. Studies were separated into immersive and nonimmersive AR/VR systems, with further categorization according to the specific methodologies used. Results: Of 110 results from the database queries, 20 publications met the inclusion criteria. There was one unblinded, randomized, control trial (RCT), one single-blinded, randomized, crossover trial (RCxT), three comparative case series, 13 noncomparative case series, and two case reports. Seven of the 20 studies were classified as nonimmersive. Six studies reported decreased PLP after AR/VR treatments, of which four reported significant reductions. One study reported a reduction in PLP with no significant difference from control conditions. Thirteen of the 20 studies were classified as immersive AR/VR. Twelve studies reported decreased PLP after AR/VR treatments, of which eight reported significant reductions. One study found no change in PLP, compared to baseline. Conclusion: The number of studies using AR/VR in PLP treatment has expanded since a 2017 review on the topic. The majority of these studies offer support for the efficacy of treating PLP with AR/VR-based treatments. Research has expanded on the customization, outcome measurements, and statistical analysis of AR/VR treatments. While results are promising, most publications remain at the case series level, and clinical indications should be cautioned. With improvements in the quality of evidence, there remain avenues for further investigations, including increased sampling, randomization, optimization of treatment duration, and comparisons to alternative therapies.

Physical Medicine and Rehabilitation Residency Applicants: A Decade of Change.

Physical medicine and rehabilitation (PM&R) has been an expanding specialty in medicine since its induction into the American Medical Association in 1947. This article quantifies the growth of PM&R by analyzing the number of residency positions and applicants as well as the characteristics of the applicants. Review of the United States (US) National Residency Matching Program (NRMP) data from 2010-2020 shows that the number of PM&R residency positions has grown by 26%, while the number of applicants has grown by 37% with a decreasing ratio of allopathic to osteopathic matched applicants. Matched applicants have had increasing Step 1 and 2 scores, abstracts, presentations, publications, and volunteer experiences. In the last decade there has been a growing interest in PM&R that outpaces residency positions and with increasingly qualified applicants. This analysis can guide residency administration and future applicants on the trends in the PM&R residency selection process.

Residency Match Trends, Racial Disparity, and Matching Amid a Pandemic.

PURPOSE: Radiation oncology has been facing an evolving crisis in recruitment for several years, and the events of 2020 to 2021 will certainly add to that crisis with the urgency of addressing systemic racial injustice amid a global pandemic. The purpose of this study is to examine applicant data to gain insight on residency match trends and evaluate these findings within the backdrop of a novel match year. METHODS AND MATERIALS: National Residency Matching Program (NRMP) data between 2009 and 2020 were assessed for the number of applicants, programs, and positions available, number of ranked applicants needed to fill positions, and successfully matched applicant data. Additionally, Electronic Residency Application Service data were evaluated for race/ethnicity identification among applicants. RESULTS: The number of applicants who ranked radiation oncology as their preferred specialty has declined for 3 consecutive years from 223 in 2017 to 155 in 2020. In 2020 the applicant-to-position ratio was at an all-time low at 0.82, and the unmatched position rate increased to 18.5%. The percentage of Black or African American applicants applying to radiation oncology has also declined to 4.9%, and this population represents 7.2% of all applicants. The number of ranked applicants needed to fill the available radiation oncology PGY2 positions increased from 4.0 in 2010 to 6.0 in 2020. CONCLUSION: Declining interest in radiation oncology among applicants, and an even further decline of black applicants, along with the challenges of interview and travel restrictions during the pandemic provide heightened concern for this year's match. Innovative efforts to expand the reach of radiation oncology to prospective applicants is needed to engage diverse, bright, and committed students for the continued progress of radiation oncology and most importantly, our patients.

Art of prevention: The importance of measles recognition and vaccination.

Measles is a viral infection that has a characteristic pattern of prodromal symptoms followed by a rash. Previously considered an inevitable childhood condition, measles is known as the "first" classic childhood exanthem. For most children, measles was a one-time, short-term illness; however, some children developed complications that led to severe sequelae and death. The introduction of the measles vaccine dramatically decreased the number of cases, but the current trend against vaccination has caused outbreaks of the condition. We propose the implementation of the AAA approach (assume, advise, and answer) as a way for providers to directly encourage the administration of the vaccine and prevent future cases of measles.
