Essential Electromyography

  • The principles of electromyography, including single-fibre electromyography and nerve conduction studies, are described simply, supported by clear diagrams and screenshots of high quality recordings. After a brief overview of anatomy, physiology, pathology and technical matters including electrodes, amplifiers and volume conduction, the way these principles aid the diagnosis of disorders of nerves, muscles and neuromuscular junctions is explained. The book concludes with the findings in common clinical conditions and explores the concept of normal vs abnormal values. This is an invaluable introductory text for trainees in clinical neurophysiology. Clinicians in specialties such as neurology, orthopaedic surgery, rheumatology, general medicine, physical medicine and rehabilitation will benefit from guidance on selecting patients for referral and assistance with the interpretation of the results. Based on the expertise of an author who has spent 25 years practising and teaching the subject, readers can be assured of a wealth of knowledge within these pages.

  • Introduction

    Treatment resistant depression (TRD) and severe depression (SD) are common among patients with depression. Patients with inflammatory joint disease (IJD) are at higher risk for developing depression compared to the general population; however, the risk for SD or TRD is not known.

    Objectives

    To examine the odds of patients with IJD for developing SD and TRD compared to non-severe and non-TRD depression.

    Methods

    This case-control study was nested within a cohort of patients with incident depression (n=443,384) identified in nationwide Swedish registers 2006-2018. Patients with SD (n=42,975) were identified through the ICD-10 code specifier, through psychiatric hospitalization and/or through suicide attempts. Patients who started a third consecutive treatment for depression were identified with TRD (n=33,830). Each patient was matched with five non-SD - or non-TRD - patients by sociodemographics and year of cohort entry. Crude and adjusted odds ratios (aOR) were calculated by conditional logistic regression with regard to a history of any IJD and specific IJDs prior to depression onset.

    Results

    Among patients with depression, those with a history of IJD did not have higher odds for developing SD (aOR 1.09 (95%CI 1.00-1.20)) or TRD (aOR 1.03 (0.93 - 1.14)) compared to patients without IJD. A history of rheumatoid arthritis was associated with a significantly higher odds for SD among patients aged 18-29 (aOR 1.55 (1.01-2.36)) and for TRD among patients aged 30-49 (aOR 1.33 (1.05-1.67).

    Conclusions

    Overall, no association was observed between history of IJD and developing SD/TRD; with the exception of younger age strata in rheumatoid arthritis.

  • Summary

    As the population of the United States ages, rheumatologic disease is quickly becoming one of the more common diagnoses encountered in the geriatric population. According to the Centers for Disease Control and Prevention, approximately 54.4 million (22.7%) US adults had doctor-diagnosed arthritis, and 23.7 million (43.5% of those with arthritis) had arthritis-attributable activity limitations. In addition to increasing prevalence, disability associated with musculoskeletal disorders is increasing. It has also been noted that worldwide disability associated with musculoskeletal disorders has more than tripled since 2004. With this increased burden of disease, there is a necessity for these diseases to be managed with an interdisciplinary approach. Through appropriate partnership of physical therapists, occupational therapists, physiatrists, orthopedic surgeons, and pain specialists, rheumatologic disease in the elderly can be effectively managed.
