Retractable Monofilament Pen Diabetic Pen

Instructions for use:

• Place the patient in supine or sitting position with shoes and socks removed.
• Tell the patient that you’re testing for loss of protective sensation, which increases the risk of foot ulcers and amputation.
• Touch the 5.07 monofilament wire to the patient’s skin on the arm or hand to demonstrate what the touch feels like.
• Instruct the patient to respond “Yes” each time he or she feels the pressure of the monofilament on the foot during the exam.
• Instruct the patient to close his or her eyes and keep toes pointing straight up during the exam.
• Hold the monofilament perpendicular to the patient’s foot. Press it against the foot, increasing the pressure until the monofilament bends into a C shape. (The patient should sense the monofilament by the time it bows.)
• Hold the monofilament in place for about 1 second.
• Press the monofilament to the skin so it buckles at one of two times as you say “Time one” or “Time two.” Have the patient identify at which time he or she was touched.
Randomize the sequence of applying the filament throughout the examination.
