Introduction: Stress is one of the most common psychological disorders. In Mexico, a study of academic stress in college students found that a high percentage of students had experienced intense anxiety (73.4%). Research on physical therapy students at the Riphah Rehabilitation Science Center show that the prevalence of perceived stress is 88%.Meditation programs in college students had resulted beneficial for the management of stress, depression and anxiety. Objective: To determine the effects of meditation on academic stress in first semester students of the degree in physiotherapy of the Autonomous University of Querétaro. Methodology: Quasi-experimental study. Participants: Thirty-six firstsemester students of the physiotherapy degree from the Autonomous University of Querétaro, a control group of 17 students and 19 in the experimental group. The experimental group was intervened for 8 weeks with guided meditation sessions with duration of 20 to 25 minutes from Monday to Friday. Both control and experimental groups were evaluated through the Academic Stress Inventory before and after the intervention program. Results: There is a significant reduction in stress levels using meditation in the experimental group (p = 0.0002). For the control group, no significant difference was found in stress p = 0.093. Conclusion: An 8-week meditation program has healthy effects on the academic stress of undergraduate physical therapy students.

OBJECTIVE: Analyze the ergonomic risk of the workers of an automotive company using the Check-List OCRA method. METHODOLOGY: An analytical cross-sectional study of the workers of an automotive company was carried out in a production area during the period from August to November 2015. A total of 17 evaluations were carried out based on the data collected from the analysis of the videos of each operation. The information was captured in the application for the OCRACheckINSHT v.1.2 Repetitive Work Risk Assessment, from which the final results were obtained, thus identifying the level of ergonomic risk. RESULTS: A total of 17 operations analyzed, 8 (23%) presented a high level of ergonomic risk, 12 (35%) were at an average ergonomic risk level, 3 (9%) were at a level of mild ergonomic risk, 6 (18%) at a very low ergonomic risk level and 5 (15%) are at an acceptable ergonomic risk level. The determinants of ergonomic risk were mainly posture, strength and frequency. CONCLUSIONS: In the production area analyzed, operations with high and medium ergonomic risk levels were found to be the highest percentage. Therefore it is necessary to implement pauses based on physical activity and stretching of upper limbs as prevention of musculoskeletal injuries as well as avoid monotony. Likewise, work rotation is suggested as a measure to prevent ergonomic injuries.
