Piriformis syndrome.

Piriformis syndrome is a condition that is proposed to result from compression of the sciatic nerve, either in whole or in part, in the deep gluteal space by the piriformis muscle. The prevalence of piriformis syndrome depends upon the diagnostic criteria being used and the population studied but is estimated by some to be 5%-6% in all cases of low back, buttock, and leg pain and up to 17% of patients with chronic low back pain. While the sciatic nerve may pierce the piriformis muscle in about 16% of healthy individuals, this frequency is no different in those with the syndrome; thus, the relationship to this anatomic finding is unclear. The most common symptoms are buttock pain, external tenderness over the greater sciatic notch, and aggravation of the pain through sitting. Many clinical signs are reported for piriformis syndrome, but the sensitivity and specificity are unclear, in part because of the lack of a uniformly accepted case definition. In the majority of cases in the literature, it appears that the diagnosis is more ascribed to a myofascial condition rather than a focal neuropathy. Electrodiagnostic studies can be useful to exclude other causes of symptoms, but there is no well-accepted test to confirm the presence of piriformis syndrome. Ultrasound imaging may show thickening of the piriformis muscle, but further research is required to confirm that this is correlated with the clinical diagnosis. Magnetic resonance imaging and neurography may hold promise in the future, but there are not yet sufficient data to support adopting these methods as a standard diagnostic tool. The initial treatment of piriformis syndrome is typically conservative management with the general rehabilitation principles similar to other soft tissue musculoskeletal conditions. Local anesthetic, botulinum toxin, and/or corticosteroid injections have been reported by some to be beneficial for diagnostic or treatment purposes. Surgical interventions have also been used with variable success.

Electrodiagnostic reporting preferences of referring physicians: An exploratory survey.

INTRODUCTION/AIMS: Electrodiagnostic (EDX) studies play a crucial role in the evaluation of patients with peripheral nervous system disorders. Accurate and succinct communication of test results is critical to patient safety and clinical decision-making. The objective of this study was to explore EDX reporting preferences of referring physicians to improve quality of communication and patient care. METHODS: An online survey was developed, and a purposive sampling strategy was used to recruit physicians in the authors' professional networks. Quantitative and qualitative survey data underwent frequency and thematic analyses, respectively. RESULTS: There were 40 respondents, including: 21 non-surgical specialists, 12 surgical specialists, and 7 family physicians. Sections rated as most critical were diagnostic impression (97%) and summary/interpretation (72%). Only 18% reported numeric data as critical to their needs, preferring this data to be formatted as bullet points or tables without nerve conduction study waveforms. Regarding the format of the data summary and diagnostic impression sections, the majority of respondents preferred bullet points rather than paragraphs. DISCUSSION: The results of this exploratory survey suggest that physicians who refer patients for EDX studies prefer reports that emphasize the interpretation of EDX data and a clear diagnostic impression, particularly in bullet point format. This project highlights important preferences and how they compare to recommended reporting guidelines, which may help improve communication and ultimately patient care. Future efforts should explore larger sample sizes with all key stakeholders in the EDX process to better understand reporting styles and preferences with greater nuance and context.

Motor Unit Number Index of the Upper Trapezius: A Meta-Analysis and Cross-sectional Study of Its Reliability.

Motor unit number index of the upper trapezius (MUNIX-Trapezius) is a candidate biomarker for bulbar lower motor neuron function; however, reliability data is incomplete. To assess MUNIX-Trapezius reliability in controls, we conducted a systematic review, a cross-sectional study (n = 20), and a meta-analysis. We demonstrated a high inter- and intra-rater intraclass correlation (0.86 and 0.94, respectively), indicating that MUNIX-Trapezius is reliable with between-study variability moderated by age and MUNIX technique. With further validation, this measure can serve as a disease monitoring and response biomarker of bulbar function in the therapeutic development for amyotrophic lateral sclerosis.

Comparison of electrodiagnostic findings in acute traumatic versus chronic non-traumatic ulnar neuropathy at the elbow.

INTRODUCTION/AIMS: A common concept is that traumatic nerve injuries are more likely axonal, and that compressive neuropathies are more likely demyelinating. The purpose of this study was to compare traumatic versus non-traumatic ulnar neuropathy at the elbow (UNE) to look for electrodiagnostic differences between the two groups. METHODS: A retrospective 3 year review of UNE patients at two academic health science centers was conducted. Patients were grouped into acute traumatic UNE versus chronic non-traumatic UNE based on clinical history. Electrodiagnostic measurements were compared between the two groups. RESULTS: There were 50 subjects with acute traumatic UNE and 41 with chronic non-traumatic UNE. Mean age and sex distribution were similar but those with traumatic UNE had a 7 month duration of symptoms, while those with chronic UNE had 29 month duration (p < .001). All electrodiagnostic measurements were similar between the two groups including compound muscle action potential amplitudes, motor conduction velocities, frequency of conduction block, sensory nerve studies, and needle electromyography. DISCUSSION: We did not find a difference between the two groups. One should not make inferences regarding acuity or etiology based on electrodiagnostic features alone.

Provocative changes in nerve conductions: Fact or fiction?

At times electrodiagnostic medical consultants (EMCs) are asked to perform studies in both a neutral position, and then again after the patient is in a provocative position that exacerbates symptoms, to assess for measurable electrophysiologic changes. While this approach might seem initially appealing, particularly when standard studies are not effective at diagnosis, empiric studies in several conditions have been unimpressive. Studies in median neuropathy at the wrist, thoracic outlet syndrome, piriformis syndrome, and radial tunnel syndrome have failed to demonstrate reproducible changes in nerve conduction studies in positions that exacerbate symptoms. Furthermore, there is lack of a plausible pathophysiologic mechanism for producing both measurable and rapidly reversible electrophysiologic changes after just a few minutes, or less, of compression. Axon loss and demyelination would not be rapidly reversible, and positional changes of 2 min or less (the durations generally studied) would be insufficient to produce measurable nerve ischemia. Last, we have gained a greater appreciation for how much nerves move within limbs with changes in joint position; this movement can lead to misleading changes in nerve conduction studies. It is thus appropriate to conclude that testing nerve conduction in provocative or symptomatic positions adds no value to electrodiagnostic testing.

Training factors that influence electrodiagnostic medicine knowledge.

INTRODUCTION/AIMS: Self-assessment examinations (SAEs) help trainees assess their progress in education. SAEs also provide feedback to training programs as to how factors in training influence examination performance. This study's goal was to examine the relationship between the number of months of training in electrodiagnostic (EDx) medicine, the number of EDx studies during training, and scores on the American Association of Neuromuscular and Electrodiagnostic Medicine SAE. METHODS: This was a retrospective study of the 2023 AANEM-SAE results. In addition to the examination score, participants were asked approximately how many EDx studies they performed in training and how many months of training they had completed. Analysis included correlation of the examination scores with months of training as well as number of EDx studies. In addition, a multivariate linear regression model was developed. RESULTS: A total of 756 participants completed the proctored examination in May 2023. Examination score was moderately and positively correlated with the number of months of training (Pearson r = .5; p < .001) as well as the number of EDx studies during training (Pearson r = .55; p < .001). Scores steadily improved with additional months of training, but leveled off after 300-400 EDx studies. Regression analysis indicated that higher numbers of EDx studies were correlated with a higher examination score even after accounting for the number of months of study. DISCUSSION: We believe that a greater number of months of training is associated with better performance on the AANEM-SAE and that greatest improvement in examination performance occurs during the first 300-400 EDx studies.

Patients, Caregivers, and Healthcare Providers' Experiences with COVID Care and Recovery across the Care Continuum: A Qualitative Study.

Introduction: During the COVID-19 pandemic, discharge timelines were accelerated and patients were moved across the continuum of care, from acute to post-acute care, to relieve the strain in health system capacity. This study aimed to investigate the COVID-19 care pathway from the perspective of patients, caregivers, and healthcare providers to understand their experiences with care and recovery within and across care settings. Methods: A qualitative descriptive study. Patients and their families from an inpatient COVID-19 unit and healthcare providers from an acute or rehabilitation COVID-19 unit were interviewed. Results: A total of 27 participants were interviewed. Three major themes were identified: 1) The perceived quality and pace of COVID-19 care improved from acute care to inpatient rehabilitation; 2) Care transitions were especially distressing; and 3) Recovery from COVID-19 stagnated in the community. Conclusion: Inpatient rehabilitation was viewed as higher quality due to the slower paced care. Care transitions were distressing for stakeholders and enhanced integration between acute and rehabilitation care were suggested to improve patient handover. A lack of rehabilitation access led to recovery stagnating for patients discharged to the community. Telerehab may improve the transition to home and ensure access to adequate rehabilitation and support in the community.

Characteristics and healthcare utilization of COVID-19 rehabilitation patients during the first and second waves of the pandemic in Toronto, Canada.

The objective of this study is to describe the healthcare utilization, and clinical and sociodemographic features of a cohort of 74 coronavirus disease 2019 (COVID-19) patients admitted to a tertiary rehabilitation hospital in Toronto, Canada. A retrospective chart review was performed using 74 charts from patients admitted to a COVID-19 rehabilitation unit between 11 April 2020 and 30 April 2021. Measures of central tendency, SDs, interquartile ranges, frequencies, and proportions were calculated to analyze clinical and sociodemographic data. A total of 74 patients were included in this study, including 33 males and 41 females. The mean age was 72.8 years, with Wave 1 patients being younger than Wave 2 patients. Sixty-six percent of total patients experienced hypertension. Mean functional independence measure score across both waves was 78 at admission and 100 at discharge. Mean length of stay was 14.6 days in Wave 1 and 18.8 days in Wave 2. This study represents some of the first data on the characteristics and outcomes of COVID-19 patients admitted to inpatient rehabilitation in Toronto, Canada across the initial waves of the COVID-19 pandemic.

Psychosocial group therapy interventions for patients with physical disabilities: A scoping review of implementation considerations.

OBJECTIVE: Group therapy is an intervention that that has been well-studied in patients with medical illness and shown to optimize patients' wellbeing and mental health resource utilization. However, its implementation and effectiveness have not been adequately studied in those with physical disabilities. This review addresses current gaps by synthesizing the literature to examine implementation considerations in the use of psychosocial group therapy for anxiety and depression in individuals with physical disabilities. METHOD: This review adhered to Arksey and O'Malley's methodological framework and the Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for Scoping Reviews Checklist. Studies were identified through MEDLINE, EMBASE, PSYCINFO, and CINAHL. Included studies were qualitative, quantitative, or mixed methods research on participants with a physical disability, and undergoing psychosocial group therapy to address anxiety/depression. RESULTS: Fifty-five studies were included in the review. The most common physical disabilities were multiple sclerosis (n = 31) and Parkinson's disease (n = 13). Group Cognitive Behavioral Therapy was the most commonly used intervention, facilitated by individuals with formal mental health training. A majority of therapy sessions included cohorts of up to 10 patients, and occurred weekly. Almost half of the studies (n = 27) reported high adherence rates (80%-99%), and a large proportion found group therapy led to improvements in their samples on a range of outcomes. CONCLUSION: Group therapies to address anxiety and depression are diverse, widely used, effective, and well-adhered to. This review may help practitioners develop, implement, and evaluate group programming for individuals with physical disabilities to address anxiety and depression.

Conceptualization, use, and outcomes associated with compassion in the care of people with multiple sclerosis: a scoping review.

OBJECTIVE: Compassion is widely regarded as an important component of high-quality healthcare. However, its conceptualization, use, and associated outcomes in the care of people with multiple sclerosis (PwMS) have not been synthesized. The aim of this review is to scope the peer reviewed academic literature on the conceptualization, use, and outcomes associated with compassion in the care of PwMS. METHODS: Studies were eligible for inclusion if reporting primary research data from quantitative, qualitative, or mixed-methods studies on the conceptualization, use, and outcomes associated with compassion in the care of PwMS. Relevant studies were identified through searching five electronic databases (CINAHL, Cochrane Library, EMBASE, MEDLINE, and PsycINFO) in January 2022. We followed the guidance outlined in the Joanna Briggs Institute (JBI) manual for evidence synthesis, and also referred to the Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for Scoping Reviews Checklist (PRISMA-ScR). Simple descriptive methods were used to chart quantitative findings, and a descriptive approach with basic content analysis was employed to describe qualitative findings. RESULTS: Fifteen studies were included (participant n = 1722): eight quantitative, six mixed-methods, one exclusively qualitative. Synthesized qualitative data revealed that PwMS conceptualize compassion as involving self-kindness, agency, and acceptance. PwMS report using self-compassion in response to unpleasant sensations and experiences. Quantitative findings suggest that compassion may mediate benefit finding, reduced distress, and improved quality of life (QoL) in PwMS, that those with the condition may become more compassionate through time, and that self-compassion specifically can be increased through training in mindfulness. In this context, greater self-compassion in PwMS correlates with less depression and fatigue, better resilience and QoL. Among studies, self-compassion was the most common outcome measure for PwMS. CONCLUSIONS: A nascent literature exists on the conceptualization, use, and outcomes associated with compassion in the care of PwMS. Further research is required to better understand what compassion means to PwMS and those caring for them. However, self-compassion can be cultivated among PwMS and may be helpful for managing unpleasant somatic symptoms and in benefit finding. Impact on other health outcomes is less clear. The use of compassion by health care providers in the care of PwMS is unstudied.

Preoperative electrodiagnostic planning for upper limb peripheral nerve transfers in cervical spinal cord injury: A narrative review.

Peripheral nerve transfer (PNT) to improve upper limb function following cervical spinal cord injury (SCI) involves the transfer of supralesional donor nerves under voluntary control to intralesional or sublesional lower motor neurons not under voluntary control. Appropriate selection of donor and recipient nerves and surgical timing affect functional outcomes. Although the gold standard of nerve selection is intraoperative nerve stimulation, preoperative electrodiagnostic (EDX) evaluation may help guide surgical planning. Currently there is no standardized preoperative EDX protocol. This study reviews the EDX workup preceding PNT surgery in cervical SCI and proposes an informed EDX protocol to assist with surgical planning. The PICO (Population, Intervention, Comparison, Outcome) framework was used to formulate relevant Medical Subject Headings (MeSH) terms and identify published cases of PNT in cervical SCI in Medline, Embase, CINAHL, and Emcare databases in the last 10 years. The EDX techniques evaluating putative donor nerves, recipient nerve branches, time sensitivity of nerve transfer and other electrophysiological parameters were summarized to guide creation of a preoperative EDX protocol. Needle electromyography (EMG) was the most commonly used EDX technique to identify healthy donor nerves. Although needle EMG has also been used on recipient nerves, compound muscle action potential amplitudes may provide a more accurate determination of recipient nerve health and time sensitivity for nerve transfer. Although there has been progress in presurgical EDX evaluation, EMG and nerve conduction study approaches are variable, and each has limitations in their utility for preoperative planning. There is need for standardization in the EDX evaluation preceding PNT surgery to assist with donor and recipient nerve selection, surgical timing and to optimize outcomes. Based on results of this review, herein we propose the PreSCIse (PRotocol for Electrodiagnosis in SCI Surgery of the upper Extremity) preoperative EDX panel to achieve said goals through an interdisciplinary and patient-centered approach.

Peer support for traumatic injury survivors: a scoping review.

PURPOSE: Peers are uniquely able to draw on their lived experiences to support trauma survivors' recovery. By understanding the functions and outcomes of peer support and the factors that impact implementation, evidence can be mobilized to enhance its application and uptake into standard practice. As such, we aimed to review the literature on peer support for trauma survivors to: examine the role of peer support in recovery; describe the nature and extent of peer support; Examine the influence of peer support on health and well-being; and identify the barriers and facilitators to developing and implementing peer support. METHODS: Scoping review methodology as outlined by Arksey and O'Malley. RESULTS: Ninety-three articles were reviewed. Peer support was highlighted as an important component of care for trauma survivors and provided hope and guidance for the future post-injury. Most peer support programs were offered in the community and provided one-on-one support from peer mentors using various modalities. Interventions were successful when they involved knowledgeable peer mentors and maintained participant engagement. Prior negative experiences and stigma/privacy concerns deterred trauma survivors from participating. CONCLUSIONS: Peer support fulfills several functions throughout trauma survivors' recovery that may not otherwise be met within existing health care systems. Implications for rehabilitationBy understanding the functions and outcomes and the factors that impact implementation of peer support, evidence can be mobilized to enhance its application and uptake into standard practice.Peers provide trauma survivors with socioemotional support as well as assistance in daily management and life navigation post-injury.Peer support provided hope and guidance for the future after injury and improved self-efficacy amongst trauma survivors.Peer support programs are most likely to be successful when they involve knowledgeable peer mentors, are flexibly delivered, align with organizations' values and priorities, and have adequate resources and funding to support their implementation.

Performance on the American Board of Physical Medicine and Rehabilitation certifying examinations: Rural and urban physicians.

BACKGROUND: Over 60 million people in the United States live in a rural community making up approximately 20% of the population. Data are minimal about the physiatrists who serve this rural population, their performance on certification examinations and how the American Board of Physical Medicine and Rehabilitation (ABPM&R) serves their ongoing educational, assessment, and practice needs. OBJECTIVE: To compare the performance of rural and urban physicians on the Part I, Part II, and maintenance of certification (MOC) examinations along with subspecialty preference and continuance of primary certification. DESIGN: Retrospective cross-sectional study. SETTING: Board-eligible PM&R physicians and certified diplomates of the ABPM&R. PARTICIPANTS: Physicians who participated in an initial certification or maintenance of certification examination with the ABPM&R between 2010 and 2019. METHODS: Comparisons of physician pass rates, mean scaled scores (aggregates), and program pass rates on ABPM&R certifying examinations were completed. Cross-reference to national database and ABPM&R practice site zip codes provided sociogeographic linkage. INTERVENTIONS: Not applicable MAIN OUTCOME MEASURES: Physician mean scaled scores, pass rates, subspecialty preferences, and primary certification status. RESULTS: There were no meaningful differences in performance on the ABPM&R Part I, II, and MOC examinations between rural and urban physiatrists. Most common subspecialty is the pain medicine certification whose diplomates most frequently drop their primary certification. Pediatric rehabilitation medicine certification is rare in rural localities and a health care disparity. CONCLUSION: The study found no meaningful differences in the performance of rural and urban physicians on the ABPM&R certifying examinations.
