The Use of Silver Oxynitrate Wound Dressings in the Treatment of Chronic Wounds: A Feasibility Pilot Study.

Objective: To evaluate the feasibility and effectiveness of a silver oxynitrate (Ag 7 NO 11 ) dressing on wound healing in patients with stalled chronic wounds.

Methods: A prospective pilot study was conducted to determine the feasibility and effect of using silver oxynitrate dressings within an outpatient setting in Alberta, Canada. A total of 23 patients (12 women and 11 men; mean age, 66.

A Scoping Review of the Use of Silver-impregnated Dressings for the Treatment of Chronic Wounds.

Topical silver agents and dressings are used to control infection and promote healing in chronic wounds, but reviews published from 2006 to 2011 found heterogeneous results regarding their effectiveness. A scoping review was conducted to examine the extent, range, and nature of research activity surrounding chronic wound care that employed silver-impregnated dressings; identify research gaps in the existing literature; and summarize the evidence to provide recommendations for future clinical studies. Ten (10) electronic databases and additional sources were screened from their inception to May 2016; search terms for the different databases included but were not limited to silver, chronic, complications, wound, ulcer, and sore.

Older adults show higher increases in lower-limb muscle activity during whole-body vibration exercise.

The purpose of this study was to compare lower limb muscle activity during whole-body vibration (WBV) exercise between a young and an older study population. Thirty young (25.9±4.

Comparison of sEMG processing methods during whole-body vibration exercise.

The objective was to investigate the influence of surface electromyography (sEMG) processing methods on the quantification of muscle activity during whole-body vibration (WBV) exercises. sEMG activity was recorded while the participants performed squats on the platform with and without WBV. The spikes observed in the sEMG spectrum at the vibration frequency and its harmonics were deleted using state-of-the-art methods, i.

Relationship Between Lower Limb Muscle Activity and Platform Acceleration During Whole-Body Vibration Exercise.

The purpose of this study was to identify the influence of different magnitudes and directions of the vibration platform acceleration on surface electromyography (sEMG) during whole-body vibration (WBV) exercises. Therefore, a WBV platform was used that delivers vertical vibrations by a side-alternating mode, horizontal vibrations by a circular mode, and vibrations in all 3 planes by a dual mode. Surface electromyography signals of selected lower limb muscles were measured in 30 individuals while they performed a static squat on a vibration platform.

sEMG during Whole-Body Vibration Contains Motion Artifacts and Reflex Activity.

The purpose of this study was to determine whether the excessive spikes observed in the surface electromyography (sEMG) spectrum recorded during whole-body vibration (WBV) exercises contain motion artifacts and/or reflex activity. The occurrence of motion artifacts was tested by electrical recordings of the patella. The involvement of reflex activity was investigated by analyzing the magnitude of the isolated spikes during changes in voluntary background muscle activity.

Vibration transmission to lower extremity soft tissues during whole-body vibration.

In order to evaluate potential risks of whole-body vibration (WBV) training, it is important to understand the transfer of vibrations from the WBV platform to the muscles. Therefore, the purpose of this study was to quantify the transmissibility of vibrations from the WBV platform to the triceps surae and quadriceps soft tissue compartments. Sixteen healthy, male participants were exposed to side-altering WBV at 2.

Determination of the optimal parameters maximizing muscle activity of the lower limbs during vertical synchronous whole-body vibration.

Purpose: To describe the most effective parameters maximizing muscle activity during whole-body vibration (WBV) exercises on a vertically vibrating (VV) platform.

Methods: The influence of (1) WBV vs. no vibration, (2) vibration frequency (25, 30, 35, 40 Hz), (3) platform peak-to-peak displacement (1.

Validity of the Optogait photoelectric system for the assessment of spatiotemporal gait parameters.

The purpose of this study was to evaluate the discriminant and concurrent (criterion-related) validity of a recently introduced floor-based photocell system (Optogait, Microgate, Bolzano, Italy) with a validated electronic walkway for the assessment of spatiotemporal gait parameters. Fifteen patients (mean age±standard deviation: 65±7 years) with total knee arthroplasty and 15 healthy matched control subjects were asked to walk at different velocities while gait variables were recorded simultaneously by the two instruments. The Optogait and the criterion instrument detected the same differences in walking parameters between patients and controls.
