Viktig studie om hvordan huden påvirker trykksensitivitet i muskler. Nevner at trykksensitiviteten sitter mest under huden i dyperliggende vev.
In studies attempting to block the skin contribution of the pressure pain sensitivity, a thoughrough assessment of cutaneous anaestesia is either not included or only a partial loss of skin sensitivity is reported. Thus, it is likely that the cutaneous mechanoreception was partly intact, which might affect the pressure sensitivity of deep tissue.
With the skin completely anaesthetised to brush and von Frey hair pinprick stimulation, skin indentation with the strongest von Frey hair caused a sensation described as a deep touch sensation.
The present data show a marginal contribution of cutaneous afferents to the pressure pain sensation that, however, is relatively more dependent on contributions from deep tissue group III and IV afferents. Moreover, a pressure sensation can be elicited from deep tissue probably mediated by group III and IV afferents involving low-threshold mechanoreceptors.
