Footing pressure

Diameters are measured using a dead-weight gauge with a specific foot pressure of weight applied with diameters measured to within 0.02 mm. The diameter is measured at three points on the suture, about V4,, and V4 of the strand length. Since the knot strength is so important. 

Arm-applied pressure to a spade is insufficient. Excavation can be accomplished quite easily by application of impact energy with spade or by foot pressure to spade. 

In a double-blind, placebo-controlled study in eight healthy men, zolpidem 10 mg produced statistically significant postural sway in the tandem stance test, and triazolam 0.25 mg was statistically significant only as defined by the polygonal area of foot pressure center (23). Zolpidem, which has a minimal muscle-relaxant effect, produced more imbalance than triazolam, which is known for its muscle relaxant effect. The authors suggested that in the use of hypnotics, sway derives from suppression of the central nervous system relevant to awakening rather than from muscle relaxation. 

It is fairly obvious that the use of a different foot pressure would, with a soft and deformable material such as rubber, produce a different result. Hence, it is not permissible to use a dial gauge with a return spring, calipers, or a travelling microscope when this standard method is specified. The errors resultant on using different pressures have been reported by Clamroth and Dobrosehke [29]. 

Tactile rehabilitation has received minimal attention in the literature or medical community. One research device sensed pressure information normally received by the fingertips and displayed it on the forehead using electrotactile stimulation [ Collins and Madey, 1974]. Subjects were able to estimate surface roughness and hardness and detect edges and corners with only one sensor per fingertip. Phillips [1988] reviews prototype tactile feedback systems that use the intact tactile sense to convey hand and foot pressure and elbow angle to users of powered prosthetic limbs, often with the result of more precise control of these devices.

Abstract— 3-D Foot Print Device was developed to measure the plantar foot pressures for normal and diabetic patients with neurotrophic ulcers. The results show that patients with peripheral neuropathy develop very high forefoot pressures as compared to normal segment of the populations. Bubble technology and new memory biomaterials insoles were used to reduce these forefoot pressures combined with providing new custom made shoes.

Plantar foot pressure data were 628 78 k Pa (values are means SE) peak pressure for 20 normal subjects and 1501 128 k Pa peak pressure for 20 patients with neurotrophic ulcers. A correlation coefficient r = 0.27 reveled a significant difference in plantar pressures between the two groups (p>0.05).
