Dialing torque preferences of people with diabetes when using insulin pens: a pilot study.

ABSTRACT:

Introduction

Ergonomic dialing torque may enhance safety and comfort when setting doses with insulin pens. Limited data are available on the correlation of dialing torque and dialing comfort.

Methods

Three studies were performed with SoloSTAR(®) (SS; Sanofi), FlexPen(®) (FP; Novo Nordisk), KwikPen(®) (KP; Eli Lilly) and FlexTouch(®) (FT; Novo Nordisk) pens. Dialing behavior was examined with 20 pen-experienced people with diabetes. Participants dialed up to the maximum dose and back down to "zero" with each pen. Hand and pen movements were recorded by video camera and rotational speeds and angles calculated for each pen. In a laboratory study, dialing torque was measured discontinuously at a speed of 120°/s, reflecting typical patient behavior. Sixteen pen-experienced people
