“…In an early study of pressure, circumferential application of 200 mmHg was established as a pain threshold relative to pressure [27]. More recently, researchers have stated that muscle cell death can occur in less than 3 to 6 hr with as little as 68 mmHg [28][29][30][31][32][33][34].…”

Abstract-The objective of this study was to investigate the effect of brimless compared with ischial ramus containment (IRC) prosthetic sockets when using vacuum-assisted suspension (VAS) on persons with a unilateral transfemoral amputation (TFA). A randomized crossover design with a 2 d accommodation was used. People with unilateral TFA (n = 9 analyzed) were enrolled. Interventions were IRC VAS and brimless VAS sockets. Main outcome measures included coronal hip angle and vertical and lateral socket movement as measured by X-ray, skin pressure measured by Tekscan, and preference measured subjectively. The brimless design was statistically equivalent to IRC in all measured coronal hip angles and vertical and lateral socket displacement. The peak/stance mean pressure in the medial proximal aspect of the socket was 322 mmHg in the IRC compared with 190 mmHg in the brimless condition. Except for medial proximal pressure, no other measures reached statistical significance. All subjects reported the brimless design to be more comfortable than the IRC in short-term preference. Brimless VAS socket design may be a clinically viable choice for people with TFA.

“…b) The pain threshold was ascertained by focussing radiant energy from a 500 watt bulb onto the blackened skin of the subject through a shutter regulated to open for three seconds (9). The amount of heat in millicalories per second per square centimeter of skin required to evoke the first perceptible sensation of pricking pain was measured.…”

“…The technique which utilizes radiant heat as a source of painful stimulation (3) was used for measuring the threshold for both "pricking" and "burning" pain. Observations were made of the amount of thermal radiation just necessary to produce the sensation of pain.…”
