The sequential stimulator for the treatment of dysphagic patients incorporates a unit which is capable of detecting a swallowing signal from the glossal or temporalis surface electromyography (SEMG). When a swallowing signal is recognized, a trigger signal is sent to the stimulation generation unit to release high voltage stimuli sequentially to the suprahyoid muscles or the masseter muscles and the pharyngeal muscles in order to assist in the elevation of the larynx. This enables the pharyngeal lumen to open more widely so that food can pass through the patient's pharynx and into the oesophagus more easily during swallowing. Thus the sequential stimulator is a device for assisting swallowing in patients with dysphagia due to a variety of causes, for instance, brain injury, cerebrovascular accident, injury of the cervical nerves, muscles weakness, or old age. The stimulator is operative only when the patient attempts to swallow and provides a physiologic stimulus and provides a means of immediate relief of the swallowing difficulty. The device is also useful for physical therapy whereby the muscles under the chin, the masseter muscles and the pharyngeal muscles can be re-educated to contract in the normal coordinated sequence.

Method and apparatus for treating poor laryngeal-elevation disorder with sequential-high voltage electrical stimulation

A wearable device that enables adjustable resistance to the extremity of a user using an attachment system and associated eddy current braking system. The wearable resistive device can be used for physical therapy made necessary due to weakness caused by neuromuscular diseases, such as stroke and cerebral palsy, orthopedic disorders, general disuse, or even for overall fitness.
