The effects of non-painful transcutaneous electrical nerve stimulation on cutaneous pain threshold and muscular reflexes in normal men and in subjects with chronic pain
TLDR
An important difference between healthy and pathological subjects is not the quality but the quantity of the changes induced by TENS, in the sense that the levels of inhibition and facilitation of the reflexes are more evident in patients with pain.Abstract:
In healthy subjects and in subjects with chronic myofascial pain of one lower limb, the following was measured in both lower limbs: (i) sequential Hoffman (H) reflex, (ii) sequential Achilles tendon (T) reflex, (iii) cutaneous pain threshold determined with electrical stimuli, before, during and after transcutaneous electrical nerve stimulation (TENS). In healthy subjects no significant differences were observed between the pain thresholds of the two limbs. During and after TENS, changes of the reflexes were related to the pain thresholds. In the pathological subjects a significant difference of pain threshold was present between the affected limb and the contralateral one. An important difference between healthy and pathological subjects is not the quality but the quantity of the changes induced by TENS, in the sense that the levels of inhibition and facilitation of the reflexes are more evident in patients with pain. Indeed, TENS induces a reset of sensory and of motor system and a parallel long lasting effect both on sensory and on muscular function, with concomitant pain relief in the pathological subjects.read more

Pain threshold variations in somatic wall tissues as a function of menstrual cycle, segmental site and tissue depth in non-dysmenorrheic women, dysmenorrheic women and men

TL;DR: It is indicated that menstrual phase, dysmenorrhea status, segmental site, tissue depth and sex all have unique interacting effects on pain thresholds, thus adding more items to the lengthy and still‐growing list of biological factors that enter into an individual's judgment of whether or not a stimulus is painful.

Is TENS purely a placebo effect? A controlled study on chronic low back pain *

TL;DR: It is concluded that TENS should be used as a short‐term analgesic procedure in a multidisciplinary program for low back pain rather than as an exclusive or long‐term treatment.

Sensory stimulation (TENS): effects of parameter manipulation on mechanical pain thresholds in healthy human subjects.

TL;DR: While high frequency, ‘strong but comfortable’ intensity, segmental stimulation produced comparable hypoalgesic levels during stimulation, this effect was not sustained post‐stimulation, and these results may have implications for the clinical use of sensory stimulation.

Dose-specific effects of transcutaneous electrical nerve stimulation (TENS) on experimental pain: a systematic review.
TL;DR: The level of hypoalgesic efficacy of TENS is clearly dependent on TENS parameter combination selection and experimental pain model and future clinical RCTs may consider these TENS dose responses.

Transcutaneous electrical nerve stimulation: effect on peripheral nerve conduction, mechanical pain threshold, and tactile threshold in humans.
TL;DR: The findings from this study suggest that at least part of Tens-mediated hypoalgesia is a consequence of a direct peripheral effect of TENS, although a "central" effect may not be excluded.

TL;DR: The gate theory appears to offer a way in which non-destru~;tive intervention into the nervous system might provide pain control without attenuated loss of neurological function, and an increased empbasis on neurophysiological research in pain has occurred.

TL;DR: Five patients out of a group of ten who had dorsal column electrodes implanted for the relief of chronic pain were examined for the influence of the stimulation on the spontaneous pain and on the thresholds for touch, vibration and cutaneous pain induced by pinching.

TL;DR: It can be concluded that the facilitation of γ motoneurones is obtaining for a low level of activation, that an inhibition of the flexor reflex afferents is obtained for a higher level and that facilitationOf the H reflex, produced by the highest levels ofactivation, indicates the lower sensibility of α mot oneurones to reticular discharge.
