Kinematic Demands Of Nucleus Arthroplasty Technology, Elizabeth J. Sander
Kinematic Demands Of Nucleus Arthroplasty Technology, Elizabeth J. Sander
Theses and Dissertations (ETD)
Recent advancements in biomaterial technologies have fostered growth in alternative surgical procedures to fusion surgery for treatment of early stages of degenerative disc disease. One application of immediate interest is that of nucleus arthroplasty (NA). Novel materials are being developed to better match the nonlinear biomechanical properties of the native tissue. The effects of changing the motion segment unit (MSU) properties via surgery (nucleotomy) or placement of a nucleus arthroplasty material, changes the effort or work required to move the altered spine condition through a prescribed kinematic path relative to the intact spine condition. The closer the loading mechanics of …
Effect Of 3-Electrode Electrical Stimulation On Current Delivery And Healing In Chronic Wounds, Hyejin Suh
Effect Of 3-Electrode Electrical Stimulation On Current Delivery And Healing In Chronic Wounds, Hyejin Suh
Loma Linda University Electronic Theses, Dissertations & Projects
Chronic wounds have been an enormous burden on the healthcare system due to their prevalence and the lack of efficacy of current treatment modalities. Over the years, electrical stimulation (ES) has been widely used in the treatment of wounds. Unfortunately, the effectiveness of this treatment is under scrutiny, since many studies have failed to report successive and/or consistent effects of ES on wound healing. This inconsistency may be due to the uneven current produced by the conventional 2-electrode delivery system (2-channel ES) and the reduced resting blood flow resulting from thermally cool treatment rooms. In this study, a new approach …
