“…instrumentation A 7-camera, 240-Hz motion analysis system (Vicon Motion Systems and Peak Performance Inc, Oxford, UK) was used to obtain the 3-D kinematics during data collection. Anatomical reflective markers were used to define joint centers and placed at the left and right anterior superior iliac spines, superior iliac crests, posterior superior iliac spines, and greater trochanters, and right femoral epicondyle, right medial and lateral malleoli, and the right first and fifth metatarsal (eg, landing 21,25,32,33 and lateral cut 6,18,28 movements), during which ankle sprains typically occur. More recently, Cordova and colleagues 7 showed that a semirigid ankle brace is more effective in reducing rearfoot angular displacement and velocity than a lace-up brace, but the lace-up brace was more effective than no brace.…”

t he ankle joint is the most commonly injured joint during sports participation. 3,13,14,19 The most recent National Collegiate Athletic Association injury data over 16 years (1988)(1989)(1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004) showed that ankle ligamentous injuries represent the highest injury rate at 14.9% of all reported injuries in 15 sports, ranging from 2.8% of all injuries for women's ice hockey to 26.6% for men's basketball. 19 Basketball, volleyball, soccer, and lacrosse are among the sports with the highest ankle injury rate. It was reported that up to 80% t Study deSign: Controlled laboratory study.t objectiveS: To examine effectiveness of an ankle brace with a subtalar locking system in restricting ankle inversion during passive and dynamic movements.t background: Semirigid ankle braces are considered more effective in restricting ankle inversion than other types of brace, but a semirigid brace with a subtalar locking system may be even more effective.t MethodS: Nineteen healthy subjects with no history of major lower extremity injuries were included in the study. Participants performed 5 trials of an ankle inversion drop test and a lateralcutting movement without wearing a brace and while wearing either the Element (with the subtalar locking system), a Functional ankle brace, or an ASO ankle brace. A 2-way repeated-measures analysis of variance (ANOVA) was used to assess brace differences (P.05).t reSultS: All 3 braces significantly reduced total passive ankle frontal plane range of motion (ROM), with the Element ankle brace being the most effective. For the inversion drop the results showed significant reductions in peak ankle inversion angle and inversion ROM for all 3 braces compared to the no brace condition; and the peak inversion velocity was also reduced for the Element brace and the Functional brace. In the lateral-cutting movement, a small but significant reduction of the peak inversion angle in early foot contact and the peak eversion velocity at push-off were seen when wearing the Element and the Functional ankle braces compared to the no brace condition. Peak vertical ground reaction force was reduced for the Element brace compared to the ASO brace and the no brace conditions. t concluSionS: These results suggest that the tested ankle braces, especially the Element brace, provided effective restriction of ankle inversion during both passive and dynamic movements.

“…Hodgson et al 16 found that the maximum vertical ground reaction force (GRF) and loading rate at toe contact significantly increased and the ankle dorsiflexion angle at toe contact significantly decreased during the drop landing onto a flat surface wearing an ankle brace. In addition, Ubell et al 19 found that participants wearing semirigid braces had significantly greater success rates in keeping balance for 3 seconds after landing with a 24-degree inversion fulcrum affixed to the heel of the shoes, compared with a laceup brace and no brace. To date, no study has been conducted to compare the 2 testing protocols, landing on an IS and inversion drop. Therefore, it is important to examine differences and similarities of the 2 protocols and their implications in future testing of ankle braces and ankle performance mechanisms under these perturbations.…”

“…In addition to these, it is quite important to ensure that proper personal protective equipment is used, instructions for usage are given, and that their maintenance is done. It has been reported that the usage of ankle braces reduce the traumas such as ankle sprain and ankle injuries which occur during landing [20]. The usage of personal protective equipment for the neck region should be considered in order to reduce the neck traumas.…”

The skydiving/parachuting sport which has recently gained popularity is also known for its accidents and injuries. However, there are a few studies related to its occupational ergonomic risks and occupational musculoskeletal diseases. It has been reported that the sudden hyperextension of the neck during the parachute opening, so called opening shock results in neck pain. It has been found that the jumpers are subjected to an average deceleration of 3-5 times the earth's gravitational acceleration (3-5 G) during parachute opening shock. It is considered that the spinal cord is destabilized by the impact of this force. This study presents the occupational cervical disc herniation occurring in the case of a subject who has been working as a skydiving/parachuting instructor for 25 years, and the ergonomic risks specific to the sports of skydiving. There is a requirement for systematic and representative studies related to the administrative measures to be taken in order to prevent the occupational diseases that may occur in the case of skydivers, the personal protective equipment to be used, and the employee.
