Only Women Report Increase In Pain Threshold Following Fatiguing Contractions Of The Upper Extremity, Kathy J. Lemley, Jonathon Senefeld, Sandra K. Hunter, Marie K. Hoeger Bement

Physical Therapy Faculty Research and Publications

Purpose

The perception of pain in response to a noxious stimulus can be markedly reduced following an acute bout of exercise [exercise-induced hypoalgesia (EIH)]. Sex differences in EIH frequently occur after exercise but may be confounded by the sex differences in muscle fatigue. The purpose was to determine if sex differences in pain relief occur after an exercise protocol when muscle fatigue is similar for both young and older men and women.

Methods

Pain perception of 33 men (15 young) and 31 women (19 young) was measured using a pressure pain stimulus on the left index finger before and after …

In Vitro Effects Of Two Silver Electrodes On Select Wound Pathogens, Linda Jean Laatsch-Lybeck, Poh Chye Ong, Luther C. Kloth

Physical Therapy Faculty Research and Publications

The use of electrical current to promote wound healing is well documented. However, little is understood about the effects of micro-amperage direct current (μADC) on growth of wound pathogens. The purpose of this project was to investigate the antibacterial effects of a silver wire/silver nylon electrode carrying μADC in vitro on several Gram positive and Gram negative bacteria. The current was delivered via silver wire and silver nylon electrodes at an amplitude of 100 μA for a 30-minute duration in an in vitro system. Results demonstrated that only silver wire carrying current inhibited bacterial growth around …

Antibacterial Effects Of A Silver Electrode Carrying Microamperage Direct Current In Vitro, Poh Chye Young, Luther C. Kloth, Linda Jean Laatsch-Lybeck

Physical Therapy Faculty Research and Publications

Currently, electrical stimulation is an accepted method used clinically to promote chronic wound healing. A literature review revealed that similar therapeutic current has been shown to suppress growth of common wound pathogens in vitro and in vivo. To date, little has been reported on the factors contributing to the antibacterial effects of microamperage direct current (μADC) stimulation. The purpose of this project was to investigate the role of electric field strength, current density, pH, and type of electrode used in vitro, to gain a better understanding of how these factors contribute to inhibiting growth of select wound pathogens. …
