Brief Summary:
This research will provide data on evaluation of the effectiveness and safety of using a passive exoskeleton designed to reduce the negative impact of static and dynamic loads associated with body tilts, lifting and holding weights on the musculoskeletal system of workers. To evaluate a passive industrial exoskeleton for back support, a protocol was developed in which individual production operations will be modeled.
This research will recruit 9 valunteers. During a 4-hour laboratory visit, each subject will perform three identical experimental tests: one test without an exoskeleton and two tests using two different modifications of the exoskeleton prototype. To avoid sequence bias, the test order will be randomized (balanced). Two types of labor operations will be simulated. One operation will consist in lifting the load, which is 20% of the volunteer's body weight, from a height of 14 cm to a surface with a height of 70 cm, the frequency of lifting is 1 time in 30 seconds. The second operation is holding a cargo weighing 5 kg in a forced working position (tilt of the body more than 30 °) for 1 minute, after which rest will follow for 1 minute, and then the work will be repeated. Both types of work will be performed for 105 minutes, then a break of 15 minutes, then 105 minutes of work. Heart rate, blood pressure, ECG (Custo) will be monitored. An ergospirometric device (Metamax) will be used to collect muscle activity data (Trust-M, Myoton), inertial sensors (Trust-M) will be used to evaluate the biomechanics of movements. In addition, questionnaires will be filled out for a subjective assessment of the use of exoskeleton prototypes (local discomfort scale, exoskeleton properties assessment questionnaire).
