It was determined those groups take more helmet collisions during a week of practice than they do in a game. Additional testing performed this year revealed an average reduction of 10% for the Guardian Cap.įor high school players who aren't as big or fast, Erin and Lee Hanson, who invented the Guardian Cap a decade ago, claim the reduction has been tested up to 33%.Īfter the Jacksonville Jaguars experimented with them in 2020, the NFL approved use of the cap in practice for offensive and defensive linemen this year. The average reduction was 5% for the ProTech. Statistical analysis of the weighted results showed the helmet with the Guardian Cap on average showed a 9% reduction in force impact compared to a bare helmet. In an attempt to duplicate the average impact speed and concussive impacts that offensive and defensive linemen experience in games, the tests used two impact velocities and three impact locations: front, side and upper. The tests were conducted using the same type of linear-impactor machine used for annual NFL-NFLPA performance evaluations of bare helmets. The study tested helmets with and without the cap under conditions that simulated impacts NFL players sustained during games from 2015 through 2019. Ann Bailey Good, a senior mechanical engineer for Biocore. The memo explained that two add-on caps - the Guardian Cap and Defend Your Head ProTech Helmet Cap - were chosen in a collaborative effort between the NFL and NFLPA to be tested by Biomechanics Consulting and Research under Dr. He didn't, but as he thought about it during the offseason, he came to this simple conclusion: "The science says it helps, so it's not really a debate at that point.''īut what have scientific studies actually revealed about the effectiveness of Guardian Caps in reducing the energy of impacts to the heads of NFL players?ĮSPN.com obtained a copy of a memo the NFL sent to team physicians, head athletic trainers and equipment managers in August 2020 when it decided to move forward with on-the-field experimentation of the cap. Paradis, 31, was offered the opportunity last season to wear the shell, which is designed to reduce the energy of impact and limit head injuries. "Squishy helmet," Paradis said with a laugh. Carolina Panthers center Matt Paradis was among about 100 NFL players who arrived for the first padded practice of training camp wearing a large, soft-shelled cover over his helmet that gave him the appearance of a "Star Wars" stormtrooper. Guardian Caps: Are the soft-shelled football helmet covers effective at limiting head injuries?ĬHARLOTTE, N.C.

Of these, 837 (91%) completed interviews at 6 weeks, 759 (82%) at 6 months, and 728 (79%) provided data at both time points. A total of 921 women participated in this study 407 in the Sphincter Tear cohort, 390 in the Vaginal Control cohort, and 124 in the Cesarean Control cohort. The cohorts were interviewed at 6 weeks and 6 months following delivery to identify symptoms of UI and FI symptoms using the Fecal Incontinence Severity Index and the Medical, Epidemiological, and Social Aspects of Aging Questionnaire, respectively. The primary goal of the study was to estimate and compare the prevalence and incidence of postpartum urinary and fecal incontinence (UI and FI, respectively) in 3 cohorts of primiparous women: (1) those who had anal sphincter disruption during vaginal delivery (2) a control group of women without clinically apparent anal sphincter disruption during delivery and (3) a second control group who underwent a cesarean delivery without labor.
The Childbirth and Pelvic Symptoms (CAPS) study was a prospective cohort study performed by the Pelvic Floor Disorders Network to study postpartum fecal and urinary incontinence in primiparous women.
