About this study
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.
Read the detailed description
This research will recruit 12 volunteers. During a 4-hour laboratory visit, each subject will perform two identical experimental tests: one test without an exoskeleton and another one using the exoskeleton. To avoid sequence bias, the test order will be randomized (balanced). The labor operation will be simulated. This operation will consist of lifting the load, which is 20 kg off the floor, walking 1.5m to a surface with a height of 70 cm to put it on, the frequency of lifting is 1 time in 30 seconds. The work will be performed for 105 minutes, then a break of 15 minutes, then 105 minutes of work. Heart rate (Polar) 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).

What is being measured
The primary outcome is the main question the study is designed to answer.
Heart rate
A Polar H10 heart rate monitor (Polar Electro, Finland) will carry all items during the entire research
Measured: 4 hours
Blood pressure (Systolic and diastolic)
A Custo med blood pressure monitor will be used by all subjects throughout the study
Measured: 4 hours
Range of motion in large joints of the upper, lower limbs and spine
Inertial sensors will be mounted on the body of the volunteer. The amplitude of the moving in the shoulder, elbow, hip, knee joints and in the thoracolumbar spine is determined. Flexion and extension, abduction and adduction, rotation are performed.
Measured: 1 hour
Metabolic cost of ergospirometric testing
A Metamax 3B instrument (Cortex, Germany) will be used to measure a metabolic cost during all labor activities, 4 hours.
Measured: 4 hours
Surface electromyography
Trust-M sensors with electrodes will be used to collect electromyographic data in accordance with the SENIAM recommendations. The muscles that will be monitored, the muscles of the arms, legs and back, which account for the maximum load. The locations of the sensors will be prepared by shaving, abrasion with sandpaper, and alcohol cleaning. The average amplitude of the EMG spectrum will be collected. The recording will be carried out at rest, standing before and after work, as well as outside work in the voltage position without exoskeleton and with it.
Measured: 1.5 hours
Myotonometry
Myotonometry will be performed with a Myoton Pro device. Parameters of the certain muscles, which get the maximum load, will be measured at rest standing before and after work, as well as outside work in a stress position without an exoskeleton and with it.
Measured: 1.5 hours
Local Comfort Rating Scale
This questionnaire is for assessing the duration of maintaining a working posture without discomfort, fixing their appearance, as well as the nature of these sensations. Points can vary from 1 to 10, where 1 is the absence of pain, 10 is unbearable pain.
Measured: 1 hours
Secondary outcomes (1)
Exoskeleton parameter evaluation form
Questionnaire on partial and general parameters of the exoskeleton and user experience
Measured: 30 minutes
