The effectiveness of the parachutist ankle brace in reducing ankle injuries in an airborne ranger battalion.

The purpose of this study was to determine if the parachutist ankle brace (PAB) decreases the number and severity of ankle injuries in an airborne Ranger battalion. A retrospective study was performed covering a 38-month period. A computer database was used to track all jump injuries with a diagnosis of ankle pain, sprain, or fracture. The frequency was calculated for ankle injuries per 1,000 jumps and the average length of medically restricted duty per ankle injury. A total of 13,782 static line parachute jumps were conducted during the study period. Without the PAB, 35 ankle injuries were seen (4.5/1,000 jumps), with 9 fractures and 316 days of medical restriction per 1,000 jumps. Using the PAB, 9 ankle injuries were seen (1.5/1,000 jumps), with 3 fractures and 71 days of medical restriction per 1,000 jumps. The correct use of the PAB appeared to significantly decrease the incidence of ankle injuries in this battalion.

Knowledge and use of birth control methods in active duty Army enlisted medical trainees.

This study was designed to determine the familiarity of medical advanced individual training (AIT) students with current methods of birth control and to evaluate the accessibility of these methods. A survey was distributed to 578 medical specialist AIT students assigned to Fort Sam Houston, Texas, for training. Results obtained show a lack of knowledge concerning the newer forms of contraceptives available. This study also indicates that barriers may exist that limit a soldier's ability to acquire prescription forms of contraception while in training.

PIP: This cross-sectional study evaluates the knowledge and use of contraceptives in medical advanced individual training students and the availability of these contraceptive methods. A 15-item proctored self-administered questionnaire was given to 564 soldiers from the 232nd Medical Battalion assigned to Fort Sam Houston, Texas. Results revealed that majority of the active duty service members were well informed on the current birth control methods. About 55.6% females and 50.8% males reported knowing emergency contraceptive pills as a method of pregnancy prevention. Condom was reportedly the most popular method of contraception among 98.8% females and 99.4% males. Lack of knowledge on newer forms of contraceptive devices was observed. Inability of obtaining contraceptives was due to unavailability of condoms, lack of time for routine check-ups, barriers in the medical system, and a general lack of information.

Psychological factors that influence traumatic injury occurrence and physical performance.

This 9 month prospective study, conducted at the US Army Sergeants Major Academy (USASGMA), examined the association of selected psychological variables (e.g., measures of tension/anxiety, sleep disturbance, Type A behavior pattern) with injury occurrence and physical performance in 126 soldiers. ANOVA and logistic regression analyses revealed significant relationships between: 1) Traumatic injury occurrence and mean tension/anxiety scores, 2) Mean self-reported sleep disturbance scores and traumatic injury occurrence, 3) The Type A behavior pattern (abbreviated Jenkins Activity Survey) and number of sit-ups repetitions completed in 2 minutes, one component of the Army Physical Fitness Test (APFT), 4) The Type A behavior pattern and total score APFT. No significant associations were found for mean tension/anxiety scores and overuse injuries, or Type A behavior pattern and two mile run time or number of push-up repetitions completed in 2 minutes. These data suggest traumatic injury occurrence is influenced by tension/anxiety and disturbances in sleep habits. Additionally, individuals with higher Jenkins Activity scores (characteristic of the Type A behavior pattern) perform better physically.
