Objectives: Although both high-frequency and burst spinal cord stimulation (SCS) have shown improved efficacy and patient satisfaction compared with conventional tonic stimulation, there are limited data directly comparing the two. This study aimed to compare both high-frequency 10,000 Hz and burst SCS in the same patients in terms of pain relief and satisfaction in those with axial back pain with or without leg pain.

Materials And Methods: This prospective, single-blind, randomized controlled trial was conducted at an outpatient pain clinic within an academic medical center.

Background: During the COVID-19 pandemic, social distancing has been employed to decrease the spread of COVID-19, especially within the geriatric population; however, the resulting loneliness and isolation carry their own detrimental effects. Loneliness resulting from the COVID-19 pandemic may also have negative implications on those with chronic musculoskeletal pain.

Objectives: The aim of this review was to identify the role of loneliness specific to the recent COVID-19 pandemic as it relates to the prevalence and severity of chronic pain in the geriatric population and to provide an overview for clinicians.

Dialogue on physician well-being was concerning even prior to onset of the COVID-19 pandemic, which introduced additional unprecedented strain on healthcare workers compounded by increased personal and family stress. This paper describes our process for a rapid needs assessment and creation of a pandemic resiliency and well-being support infrastructure for physicians and healthcare staff at an academic medical center. In March 2020, executive leadership from our health system and physician group created a Resiliency and Support Steering Committee (RSSC) for rapid development of a pandemic needs response for our healthcare providers.

Spinal cord stimulation (SCS) is commonly utilized for treatment and management of chronic intractable low back and lower extremity pain. Although SCS is an overall low-risk procedure, there are potential life-threatening complications, including surgical site infections, such as an epidural abscess. Immunosuppression, a risk factor for epidural abscess, is becoming more common as an increasing number of patients are being treated with biologics for a multitude of autoimmune disorders.

Background: There is limited research regarding the prevalence of post-traumatic stress disorder (PTSD) in civilian multidisciplinary pain clinics. Controlled studies have only examined specific patient populations, such as those with motor vehicle accidents, war veterans, work-related injuries, back pain, and headache.

Objective: The purpose of this study was to estimate the prevalence of PTSD symptoms in patients with chronic pain at a large multidisciplinary pain clinic.

Objectives: Cancer pain is common and difficult to treat, as conservative medical management fails in approximately 20% of patients for reasons such as intolerable side-effects or failure to control pain. Intrathecal drug delivery systems (IDDS), while underutilized, can be effective tools to treat intractable cancer pain. This study aims to determine the degree of pain relief, efficacy, and safety of patients who underwent IDDS implantation at a multidisciplinary pain clinic.

The present study furthered the concept of simulation-based medical education by applying a personalized active learning component. We tested this novel approach utilizing a noninvasive hemodynamic monitor with the capability to measure and display in real time numerous hemodynamic parameters in the exercising participant. Changes in medical knowledge concerning physiology were examined with a pre-and posttest.
