RT journal article T1 Comparison of Traditional Physical Intervention Techniques vs. Operational Tactical Procedures and Techniques in the Use of Force during Police Arrests A1 Vera Jiménez, José Carlos A1 Villero-Carro, Domingo A1 Pastor Fernández, Andrés A1 Shippen, James A1 Ferreiro González, Marta A1 Vera Jurado, José Carlos A1 Álvarez Saura, José Ángel A1 Ayuso Vilacides, Jesús A2 Ingeniería Mecánica y Diseño Industrial A2 Química Analítica A2 Química Física K1 ergonomic K1 occupational risk prevention K1 police physical intervention K1 use of force K1 operational tactical procedure K1 motion capture technology AB Background: A set of relevant police ergonomic parameters (PEP) have been usedfor the assessment and prevention of occupational risks involved in police physical interventions(PITs). Through this set of PEPs, a comparison has been made between two traditional PITs againsttwo novel OTPs (operational tactical procedures). (2) Method: The data have been collected bymeans of a motion capture suit fitted with 19 inertial measurement units (IMUs). A specific andpowerful software package specific for ergonomic analysis has been used to manage the largeamount of data registered and to generate a series of three-dimensional plots. Traditional PITs andnewer OTPs have been performed for their analysis. Specifically, the PEPs corresponding to theimplementation of four PITs have been analyzed by collecting the measurements provided by aset of IMUs installed on a motion capture suit, and their occupational risk assessments have beencompared against those corresponding to newer OTPs. (3) Results: For the four PITs, the PEPs havebeen analyzed with the measured values from the IMUs, throughout the duration of each technique.The two traditional intervention techniques have scored higher than the new OTPs in the REBAsystem, the asymmetry angle, L5-pelvis shear and joint contact forces, and the total muscle powermeasurements. (4) Conclusions: It has been confirmed that the new OTPs minimize the risk ofinjuries, since their PEPs reached lower values than those corresponding to the traditional PITs, whichare still being taught at police academies.
