[Technic for research on pain sensitivity. Practical note].
A disposable hypodermic needle introduced into the end of its cover at right angles represents a useful tool for the determination of sensitivity to pain. This tool is more comfortable to use for the examiner and permits more adequate measurement of the muscular force used for the different stimuli when compared with pins, needles and sharp tools specially manufactured for the evaluation of superficial cutaneous sensation to pain.
