Nevertheless up to date no prospective randomised controlled trial has proven the superiority in preventing trauma when falling from a great height instead of a free fall. The aim of this prospective randomised controlled trial was to prove the effectiveness of a parachute when falling from great height. In this prospective randomised-controlled trial a commercially acquirable rag doll was prepared for the purposes of the study design as in accordance to the Declaration of Helsinki, the participation of human beings in this trial was impossible. Twenty-five falls were performed with a parachute compatible to the height and weight of the doll. In the control group, another 25 falls were realised without a parachute.

Objectives: To determine whether parachutes are effective in preventing major trauma related to gravitational challenge. Design: Systematic review of randomised controlled trials. Data sources: Medline, Web of Science, Embase, and the Cochrane Library databases; appropriate internet sites and citation lists. Study selection: Studies showing the effects of using a parachute during free fall. Results: We were unable to identify any randomised controlled trials of parachute intervention.

Volunteers Jumped with or without a Parachute to Gauge Its Effectiveness

In the examiner's comments were basically just a series of complaints about the poor quality of candidate "just can't get good candidates these days". Fortunately, in the college offered some guidance as to what was expected. Vincent, Jean-Louis. Jadad, Alejandro R. Randomized controlled trials: questions, answers, and musings. Blackwell Pub.

Kristi L. BMJ Dec Both civilian and military jumpers use parachutes to reduce risk for injury, but is there any objective evidence that these devices work?

In such an experiment, a random sorting leads to only some subjects getting the real intervention being tested. The first known RCT took place in , when Dr. James Lind, surgeon on the HMS Salisbury , staked out his place in history by giving some scurvy patients citrus fruits. At first, anyway. Then all the sailors got citrus, as it became obvious that scurvy was preventable through the inclusion in the diet of vitamin C via consumption of oranges, lemons and—of key importance to etymologists—limes, which led to all British sailors, and then all Brits in general, to become known as Limeys.

We think that everyone might benefit if the most radical protagonists of evidence based medicine organised and participated in a double blind, randomised, placebo controlled, crossover trial of the parachute.
