Parameter selection and electrode placement of neuromuscular electrical stimulation apparatus
First Claim
1. A method of treatment and prevention of deep vein thrombosis in a lower extremity of an immobilized patient, the method comprising:
- placing a plurality of electrodes on an anterior portion of at least one knee of the immobilized patient, proximal a common peroneal nerve of said patient; and
applying an electrical current to said electrodes while the patient remains immobilized thereby stimulating the common peroneal nerve transcutaneously, such that dorsiflexion muscle stimulation is produced, whereby blood flow in the deep leg veins of said patient is increased with minimal pain imparted to said patient.

Abstract
A method of neuro-muscular electrical stimulation for treatment and prevention of venous thrombosis and pulmonary embolism employs electrodes attached to an anterior portion of a patient'"'"'s knee, immediately proximal the common peroneal nerve. Electrical stimulation is comprised of trains of pulse modulated sinusoids where each pulse has a rise time of about 1 second, a fall time of about 0.5 seconds, and a plateau (on time) of about 1 to 10 seconds. Peroneal nerve stimulation is achieved thereby causing passive stretching of the gastrocnemius and soleus muscles (major posterior calf muscles) rather than a contraction for creating a blood pumping action.

10. A method of treatment and prevention of deep vein thrombosis in a lower extremity of an immobilized patient, the method comprising:
-
(a) placing a first plurality of electrodes on an anterior portion of a first knee of the immobilized patient, said electrodes placed proximal a common peroneal nerve of said patient and a second plurality of electrodes on an anterior portion of a second knee of the immobilized patient, said electrodes placed proximal a common peroneal nerve of said patient; (b) applying an electrical current for a predetermined period of time to said first electrodes on said first knee while the patient remains immobilized thereby stimulating the common peroneal nerve on said first knee transcutaneously, such that dorsiflexion muscle stimulation is produced; (c) applying an electrical current for a predetermined period of time to said second electrodes on said second knee while the patient remains immobilized thereby stimulating the common peroneal nerve on said second knee transcutaneously, such that dorsiflexion muscle stimulation is produced; and (d) repeating steps (b) and (c). - View Dependent Claims (11, 12)
