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 lifting and holding weights and having workspace over head on the musculoskeletal system of workers. To evaluate a passive industrial exoskeleton for upper limb 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's cycle will consist of lifting the load, which is 5-10 kg off the table, holding it over head and touching 4 points in order on a horizontal plate for 2 min. After this volunteer is resting for 1 min. 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.

  1. Heart rate

    A Polar H10 heart rate monitor (Polar Electro, Finland) will carry all items during the entire research

    Measured: 4 hours

  2. Blood pressure (Systolic and diastolic)

    A Custo med blood pressure monitor will be used by all subjects throughout the study

    Measured: 4 hours

  3. 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

  4. Metabolic cost of ergospirometric testing

    A Metamax 3B instrument (Cortex, Germany) will be used to measure a metabolic cost during all labor activities.

    Measured: 4 hours

  5. 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

  6. 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

  7. 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)
  1. Exoskeleton parameter evaluation form

    Questionnaire on partial and general parameters of the exoskeleton and user experience

    Measured: 30 minutes

Questions about this trial

What is this clinical trial studying?

A study testing Passive industrial exoskeleton for the upper limb and The protocol will be performed without exoskeleton in people with Prevention of Diseases of the Musculoskeletal System, run by Federal State Budgetary Scientific Institution "Izmerov Research Institute of Occupational Health" at 1 site in Russia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Russia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Heart rate (time frame: 4 hours). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Oct 2020.
