John Henryism-racial stressors among older black men with low back pain.

The relationship between adaptive pain-coping skills, such as John Henryism, and pain and function remains unclear in non-Hispanic Black populations. This cross-sectional, observational study included sixty older Black men with low back pain in Jacksonville, Florida. Key measures were: self-reported 0-10 pain intensity in the past 24 h, 13-item pain catastrophizing, functional performance from the Back Performance Scale, and the John Henryism Active Coping Scale.

Multichannel mapping of in vivo rat uterine myometrium exhibits both high and low frequency electrical activity in non-pregnancy.

The uterus exhibits intermittent electrophysiological activity in vivo. Although most active during labor, the non-pregnant uterus can exhibit activity of comparable magnitude to the early stages of labor. In this study, two types of flexible electrodes were utilized to measure the electrical activity of uterine smooth muscle in vivo in anesthetized, non-pregnant rats.

Steady-state approximations for Hodgkin-Huxley cell models: Reduction of order for uterine smooth muscle cell model.

Multi-scale mathematical bioelectrical models of organs such as the uterus, stomach or heart present challenges both for accuracy and computational tractability. These multi-scale models are typically founded on models of biological cells derived from the classic Hodkgin-Huxley (HH) formalism. Ion channel behaviour is tracked with dynamical variables representing activation or inactivation of currents that relax to steady-state dependencies on cellular membrane voltage.

A descriptive study of physical function and performance in older black men with low back pain.

The purpose of this paper is to describe physical function and performance scores and examine the relationships between measures of physical performance in older Black men with low back pain. The Mobility, Aging, Pain, and Disparities study used a cross-sectional, observational design to objectively measure physical performance on the Short Physical Performance Battery (SPPB), the Back Performance Scale (BPS), and the 400-meter Walk Test along with subjective ratings of pain intensity in the past 24 hours. Sixty community-based Black men aged 61-87 (x̄= 70 ± 6) years had an average BPS score of 7.

Improvement Opportunities for PAINReportIt Delivered on a Wireless Tablet: Rated by Black Older Men With Low Back Pain.

Health care professionals and researchers can implement technology to improve older adults' acceptability of providing health information and to better include older adults in sharing information with health providers. However, older adults' engagement with technology remains low. This study focused on 60 Black older men (mean age = 70 years, = 6 years) with low back pain who completed the 13-item Computer Acceptability Scale after using the PAINReportIt software on an Apple iPad.
