Trends of Opioid Usage in Surgical Patients in a Small Community Hospital: Analysis of Patient Data Between 2017 and 2021.

The purpose of our study was to quantify and analyze the annual opioid usage in surgical patients at Wood County Hospital (WCH) between 2017 and 2021. : In this retrospective study, patient data between 2017 and 2021 was analyzed to determine the oral morphine milligram equivalent (MME) of opioids used in surgical patients at WCH. Annual MME prescribed per admission was compared each year using one-way ANOVA followed by Tukey post hoc test.

Strength evaluation of prosthetic check sockets, copolymer sockets, and definitive laminated sockets.

A prosthesis encounters loading through forces and torques exerted by the person with amputation. International Organization for Standardization (ISO) standard 10328 was designed to test most lower-limb prosthetic components. However, this standard does not include prosthetic sockets.

Tensile strength and impact resistance properties of materials used in prosthetic check sockets, copolymer sockets, and definitive laminated sockets.

Prosthetic sockets serve as the interface between people with amputations and their prostheses. Although most materials used to make prosthetic sockets have been used for many years, knowledge of these materials' properties is limited, especially after they are subjected to fabrication processes. This study evaluated tensile and impact properties of the current state-of-the-art materials used to fabricate prosthetic check sockets, copolymer sockets, and definitive laminated sockets.

Pneumatic muscle actuator for resistive exercise in microgravity: test with a leg model.

Introduction: A proof-of-concept demonstration is described in which a DC servomotor (simulating the quadriceps of a human operator) rotated a pulley 90 degrees (simulating knee extension). A pneumatic muscle actuator (PMA) generated an opposing force (antagonist) to the rotating pulley. One application of such a device is for use in microgravity environments because the PMA is compact, simple, and of relatively small mass (283 g).

Characterisation of a phenomenological model for commercial pneumatic muscle actuators.

This study focuses on the parameter characterisation of a three-element phenomenological model for commercially available pneumatic muscle actuators (PMAs). This model consists of a spring, damping and contractile element arranged in parallel. Data collected from static loading, contraction and relaxation experiments were fitted to theoretical solutions of the governing equation for the three-element model resulting in prediction profiles for the spring, damping and contractile force coefficient.
