Method and apparatus for transdermal stimulation to treat overactive bladder and other medical ailments are described herein. The method may generally comprise non-invasively positioning a first portion of a patient's body relative to an electrical stimulator such that a target nerve within the first portion of the body is in proximity to the electrical stimulator, delivering an electrical stimulus from the electrical stimulator to the target nerve, detecting electrical conduction through a response nerve or detecting a muscular response caused by an electrical conduction through the response nerve via at least one sensor positioned along a second portion of the body, receiving a signal from the at least one sensor indicative of the detected electrical conduction or muscular response thereby providing feedback about the existence of neuropathic-irresponsiveness along the target nerve, and adjusting stimulation parameters of the electrical stimulator based on the feedback.

A referred sensation or neural haptic wearable includes an electrode array for transdermal stimulation of a sensory nerve that itself innervates a body part distal to a worn location of the referred sensation wearable. The transdermal stimulation is configured to induce an electrical current or voltage that evokes a sensory impression at an area innervated by the sensory nerve, not at the stimulated sensory nerve itself. In one implementation, the referred sensation wearable takes a finger ring form factor worn on a proximal phalanx of an index finger. In this configuration, the referred sensation wearable can stimulate a portion of a branch of the median nerve extending through the index finger. Upon stimulation of the median nerve, a user wearing the finger ring may perceive pressure applied to the user's fingertip.
