Current treatment options for Overactive Bladder and Urinary Incontinence include exercise and behavioral modifications, pharmacological therapies, surgical intervention, and neuromodulation. Although each of these treatments is used in the treatment of individuals with these conditions, each has severe limitations. Building on the limitations of existing therapies, and with the distillation of lessons learned from the field of pulsed electric stimulation, the present invention employs Low Frequency Induction Therapy for the delivery of an effective, cost efficient, noninvasive alternative to available treatment options. The device of the present application allows for consistent, user-friendly modulation of the pudendal nerve and the sacral plexus, via pulsed electromagnetic stimulation of the posterior tibial nerve, on an outpatient basis. The device has two primary components: a programmable Logic Controller (LC), which generates the required current, and a Conductive Wrap (CW), through which the current is channeled in generating the pulsed electromagnetic fields.

Methods and apparatuses (including systems, devices, etc.) for the treatment of neurological disorders, and particularly multiple sclerosis (MS) by the application of electromagnetic fields (EMF), and in particular, pulsed electromagnetic fields (PEMF), including a subset of PEMF in a radio frequency domain (e.g., pulse-modulated radio frequency or PRF). This treatment may prevent or delay the onset, and / or may reduce the severity of the onset of MS and MS-related symptoms.

A method for treating a wound of an individual and for enhancing a rate of wound healing by applying, for a first period of time, a negative pressure treatment to the wound without applying a pulsed radio frequency treatment; and applying, for a second period of time subsequent to the first period time, a pulsed radio frequency energy treatment to the wound while maintaining the negative pressure treatment to enhance the rate of wound healing. The negative pressure treatment and the pulsed radio frequency energy treatment are applied concurrently for the duration of the second period of time.
