Transcutaneous Electrical Nerve Stimulation (TENS) for Advanced Cancer Pain Patients

"* Frequency: 100 Hz~* Intensity: individual; TENS should be clearly perceptible but not painful; impulse width is coupled with intensity~* Mode: intensity modulation (40% decrease every 0.5 seconds)~* TENS device: ARTROSTIM® SELECT~* Channels: 2~* Electrodes: 4 (5x5cm), placed on site of pain (a little more proximal if allodynia is present)"

"* Frequency: 100 Hz (conventional for High TENS; Placebo is achieved by reduction of intensity, see below)~* Intensity: The device is on and will be up-regulated together until the first sensation is perceptible. Then the activated device will be down-regulated minimally (no sensation perceptible) and this configuration will be retained.~* Mode: continuous~* TENS device: ARTROSTIM® SELECT~* Channels: 2~* Electrodes: 4 (5x5cm), placed on site of pain (a little proximal if allodynia is present)"
