Abstract: A method for assessing nerve fiber excitability is disclosed. The method comprises: arranging an electrode in contact with skin of a person; determining a first and a second threshold value based on a stimulation current pulse of a first and a second waveform, respectively; wherein said determining of the first threshold value and said determining of the second threshold value each comprises: repeatedly providing a stimulation current pulse of the first or second waveform, respectively, through the electrode, wherein a stimulation current strength is altered between repetitions; and receiving signals from an interaction element with which the person interacts, said signals from the interaction element providing an indication of the first threshold value or the second threshold value, respectively, corresponding to a stimulation current strength necessary to be perceived by the person; and determining at least one measure of psychophysical perception based on the determined first and second threshold values.

Abstract: The present invention describes a system for inducing at least compressional or shear force on a subject and evaluating pain modulation, spatial and/or temporal summation of pain, or descending inhibition of pain in the subject, said system comprising a cuff unit comprising an inflatable cuff having at least two chambers or comprising at least two inflatable cuffs having one or more chambers each, each chamber having a coupling for connection to a compressor or other activator device; a compressor or other activator device arranged to provide inflation; and a computer unit with a control function, said control function directed to control of inflation rates and independent control of each chamber. The present invention is also directed to an inflatable cuff for a system according to above and also to the use and methods involving the use of such a system.

Abstract: It is possible to effectively treat moderate to severe visceral pain by administering analgesic medications comprising the opioid oxycodone or pharmaceutically acceptable salts thereof. Visceral pain and especially acute (i.e. non-chronic) visceral pain can be effectively treated by administering oxycodone at a dosage which is lower than the corresponding dosage of the other opioids like morphine.

Abstract: A device for evoking a temporal summation of pain in a subject. The device comprises a stimulation element (SE) arranged generating a physical stimulation on a skin surface area of at least 20 cm2 according to a control signal (CS), where the stimulation (PS) evokes pain in the subject. A processor (PR) generates the control signal (CS) to the stimulation element (SE) so as to provide a repetitive stimulation pattern comprising at least repetitions of: a)applying stimulation for a period (SP) of 0.5-120 seconds, b)stopping stimulation for a period (TP) of 0.5-20 seconds. Preferred periods are 1-3 seconds for both stimulation and intermediate stopping periods. The stimulation element may include an inflatable tourniquet arranged for providing a compressional stimulation of an arm or a leg. However, other types of stimulation elements may be used such as electric, heating, mechanical stimulation or the like may be used.
