PinPrick Stimulators
MRCs PinPrick stimulators are used for quantitative
sensoric testing (QST) of pain and perception thresholds.
They allow a reproducible measurement and documentation of
nociceptor activation of the skin. Thus, they enable a
better diagnostic of symptoms of neuropathologic pain and
the investigation of mechanisms that
are connected with chronic pain.
The tactile stimulators have been developed and introduced
by Prof. Rolf-Detlef Treede and PD Dr. Walter Magerl
(Department of Neurophysiology, Medical Faculty Mannheim,
University of Heidelberg). They
are used by the members of the
German Research Network on Neurophathic Pain (DFNS) and validated by the European
Federation of Neurological Societies.
The PinPrick-Sets are directly available from
us.

Applications
Pinprick stimulation ...
- is used to assess gain and loss of mechanical sensory functions
- is one important contribution to characterize the somatosensory phenotype of patients with neuropathic pain
- provides quantitative data for mechanical detection and pain thresholds as well as stimulus/response functions
- provides quantitative data for pain summation to repetitive stimuli
- is an important step towards mechanism based treatment of pain syndromes
- is a reproducible method to diagnose changes of pain sensitivity like mechanical hyperalgesia or dynamic mechanical allodynia
- is used to investigate the central sensitization to A-fibre nociceptor input
- enables the validation of paint treatment concepts by standardized protocols and absolute reference values

Product description
- One set includes seven weighted pinprick stimulators for different
pressures (between 8 and 512 mN)
- Tips have a flat contact area of 0.25 mm in diameter
with a controlled edge curvature
Accessory: Disinfection unit
For easy and safe disinfection of the PinPrick stimulators we
offer the disinfection unit as accessory.
The glass jar can
be filled with a standard disinfectant for medical
products. The PinPrick holder ensures dipping the pins into the disinfectant.
