Abstract

Introduction:

Shackled maneuver was poorly studied in specific literature despite being a technique used every day for security and police forces. The use of new technologies had reported important benefits in learning process and could improve shackled learning process. Therefore, the objectives of the present research were: (i) to analyze the effect of an audiovisual training on the efficiency in shackled technique in three different stress situations and (ii) to study the week point in the shackled maneuver to know how to improve the audiovisual training.

Methods:

Technical procedures in shackle techniques in 3 different situations of 26 male soldiers were analyzed after an audiovisual session. The situations were normal, alert and danger. All the shackle interventions were filmed by a video camera and were analyzed later. Shackle maneuver was divided in approach to the subject, subject control, placing the first shackle, limb immobilization, placing the second shackle, frisk and transfer. Every part of the shackle maneuver was evaluated with 10, 5 or 0 point.

Results:

Maneuver efficiency decreased with the stress. There was significant difference in the placement of the second phase shackle between the normal and alert situations and in all the situations the limb immobilization phase obtained the lower values. Furthermore, the execution time was lower in normal (40.30 s) than in alert (120.08 s) and danger situations (180.36 s).

Conclusion:

A short audiovisual training was enough to learn the proper shackled procedure in non experimented soldiers with a low technical level in the limb immobilization phase and differences between the stress situation in the placing the second shackle phase. Also, the increase in stress caused an increase in the maneuver time, and an increase in number of the video reproductions.

Keywords: Audiovisual, immobilization, shackled, soldiers, stress, subject control.
