Similarities and differences between men with self-reported lifelong and acquired difficulty reaching ejaculation.

Men with delayed ejaculation are often categorized into lifelong and acquired subtypes, yet little is known about similarities and differences between these groups. In this study, we examined whether delayed ejaculation subtypes differed on various demographic, diagnostic, relationship, and sexual activity/satisfaction variables. We drew 140 men reporting moderately-severe to severe difficulty reaching ejaculation during partnered sex (occurring during ≥75% of sexual events) from a convenience sample of over 3000 respondents obtained through an opt-in, multinational, online survey.

Automatically evaluating balance using machine learning and data from a single inertial measurement unit.

Background: Recently, machine learning techniques have been applied to data collected from inertial measurement units to automatically assess balance, but rely on hand-engineered features. We explore the utility of machine learning to automatically extract important features from inertial measurement unit data for balance assessment.

Findings: Ten participants with balance concerns performed multiple balance exercises in a laboratory setting while wearing an inertial measurement unit on their lower back.
