The purpose of this study was to determine the effects of video-game experience and flight-stick position on flying performance. The study divided participants into 2 groups; center- and side-stick groups, which were further divided into high and low level of video-game experience subgroups. The experiment consisted of 7 sessions of simulated flying, and in the last session, the flight stick co...

The stick index of a knot is the least number of line segments required to build the knot in space. We define two analogous 2-dimensional invariants, the planar stick index and the spherical stick index. We find bounds on these quantities in terms of other knot invariants, and give planar stick and spherical stick constructions for torus knots and for compositions of trefoils.

In the last decade, dramatic changes in lacrosse stick design are believed to be associated with changes in the play of the game; however, there is a limited understanding of how the lacrosse stick propels the ball. We predicted that the lacrosse stick would perform as a passive extension of the player's hand and hypothesized that ball shot speed would be equal to the speed at the tip of the st...

Quantification of plantar tissue behavior of the heel pad is essential in developing computational models for predictive analysis of preventive treatment options such as footwear for patients with diabetes. Simulation based studies in the past have generally adopted heel pad properties from the literature, in return using heel-specific geometry with material properties of a different heel. In e...

HYPOTHESIS Plantar heel pain (plantar fasciitis) is a common and disabling condition. A variety of treatment options are available to patients with plantar heel, however the evidence for these treatments is generally weak and the best way to manage plantar heel pain remains unclear. Trigger point dry needling is increasingly used as an adjunct therapy for musculoskeletal pain. In patients with ...

A 6 day old boy sustained scalds to his right foot from application of a "warm nappy" to increase blood flow to facilitate heel pricking for a routine Guthrie test. It is proposed that active warming of the heel in isolation is not necessary in heel blood sampling.

Heel ulcers are a costly and preventable complication of lower-extremity immobilization, but they still occur with some regularity. A technique using a short leg posterior splint that suspends the heel away from the splint is described. This modification completely removes pressure the heel to prevent decubitus ulcer formation. This technique is simple, inexpensive, and effective.

background : accidental needle-stick injuries (nsis) are a hazard for health-care workers and general public health. nursing workers are at high risk for occupational exposure to blood-borne pathogens (such as hbv, hcv and hiv) via sharp injuries of needle stick. methods : this descriptive analytical cross-sectional study was done on 158 nursing workers of khanevadeh hospital in tehran to study...
