2. Burst TENS low frequency stimulation is usually most effective for radiating projected pain in the arms and legs rhizopathy for conditions with reduced or changed sensory of touch for deep muscular pain or when the post treat ment effect of Conventional TENS is too short Burst TENS treatment alleviates pain by stimulating muscles to release the body s own morphine like substances endorphins Place the electrodes on a muscle in the painful area so that a visible contraction occurs or on acupuncture points the painful area The stimulation should feel pleasant and give visible muscle contractions Remember that the patient often feels the stimulation clearly before contractions become visible Modulated pulse duration stimulation is a type of high frequency stimulation where the pulse duration varies continuously This can cause an undulating sen sation which may be more pleasant than a constant pulse duration Use program 3 for pain alleviation and a massage effect on muscles like the trapezius Examples of indications Electrodeplacement no Neck pain Shoulder pain Elbow pain Rheumatic pain Fractured rib Lumbago Menstrual pain Phantom limb pain Hip pain Osteoarthritic pain in the knee 17 18 Wound healing Mononeuropathy Central pain Cervical rhizopathy Sciatica Knee pain Trapezius pain Lumbago For more examples see Program 1 PROGRAM LOCK The stimulator can be locked to prevent changing of
