OBJECTIVE: To investigate the effectiveness of high-voltage monophasic pulsed current (HVMPC) as an adjunct to a standard wound care for the treatment of Stage II and III pressure ulcers (PrUs).

DESIGN: Prospective, randomized, double-blind, controlled clinical study.

SETTING: Two nursing and care centers.

PATIENTS: Patients with PrUs that did not respond to previous treatment for at least 4 weeks were randomly assigned to the electrical stimulation (ES) group (25 patients; mean age of 79.92 ± 8.50 years; mean wound surface area [WSA] of 10.58 ± 10.57 cm²) or to the control group (24 patients; mean age of 76.33 …

Sensory Electrical Stimulation Improves Foot Placement During Targeted Stepping Post-Stroke, Eric R. Walker, Allison Hyngstrom, Brian D. Schmit

Physical Therapy Faculty Research and Publications

Proper foot placement is vital for maintaining balance during walking, requiring the integration of multiple sensory signals with motor commands. Disruption of brain structures post-stroke likely alters the processing of sensory information by motor centers, interfering with precision control of foot placement and walking function for stroke survivors. In this study, we examined whether somatosensory stimulation, which improves functional movements of the paretic hand, could be used to improve foot placement of the paretic limb. Foot placement was evaluated before, during, and after application of somatosensory electrical stimulation to the paretic foot during a targeted stepping task. Starting from standing, …

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. …

Chronic Dermal Ulcer Healing Enhanced With Monophasic Pulsed Electrical Stimulation, Jeffery A. Feedar, Luther C. Kloth, Gary D. Gentzkow

Physical Therapy Faculty Research and Publications

The purposes of this randomized, double-blind, multicenter study were to compare healing of chronic dermal ulcers treated with pulsed electrical stimulation with healing of similar wounds treated with sham electrical stimulation and to evaluate patient tolerance to the therapeutic protocol. Forty-seven patients, aged 29 to 91 years, with 50 stage II, III, and IV ulcers were randomly assigned to either a treatment group (n=26) or a control (sham treatment) group (n=24). Treated wounds received 30 minutes of pulsed cathodal electrical stimulation twice daily at a pulse frequency of 128 pulses per second (pps) and a peak amplitude of 29.2 mA …

Acceleration Of Wound Healing With High Voltage, Monophasic, Pulsed Current, Luther C. Kloth, Jeffery A. Feedar

Physical Therapy Faculty Research and Publications

The purpose of this study was to determine whether high voltage electrical stimulation accelerates the rate of healing of dermal ulcers. Sixteen patients with stage IV decubitus ulcers, ranging in age from 20 to 89 years, participated in the study. The patients were assigned randomly to either a Treatment Group (n = 9) or a Control Group (n = 7). Patients in the Treatment Group received daily electrical stimulation from a commercial high voltage generator. Patients in the Control Group had the electrodes applied daily but received no stimulation. The ulcers of patients in the Treatment Group healed at a …
