About this study

Official title: Comparing Conventional Abdominal Ultrasound Scanning Versus a Robotic Assisted Ultrasonography System (ROBUST): a Pilot Study

Work-related musculoskeletal disorders (WRMSD) among sonographers/radiographers are prevalent in the healthcare industry. This pilot study will evaluate the use of a robotic assisted ultrasonography system (ROBUST) against the conventional abdominal ultrasound scanning procedure. The ROBUST will be developed to provide 6 degrees of freedom to allow radiographers to perform abdominal scanning without having to reach over patients.

10 sonographers with at least 5 years of experience will be recruited from SGH and SKH, to perform abdominal ultrasound scans on healthy volunteers. Each sonographer will be randomly assigned to scan a volunteer using conventional abdominal ultrasound scanning procedure and with ROBUST respectively. The study will be done in 2 phases, separated by at least a 1-month interval between scans.

Phase 1: Scanning of volunteer using conventional abdominal ultrasound scanning procedure.

Phase 2: Scanning of volunteer using ROBUST. Outcome measures will include ultrasound image quality, sonographer feedback and comfort level as well as satisfaction feedback from healthy volunteers. A panel of 4 reviewers, consisting of 2 radiologists and 2 senior radiographers will be invited to grade the images, using a 3-point Likert scale. The duration of each scanning will be recorded. The comfort level reported by sonographers will be assessed using the SGH Comfort Level Survey. In addition, the comfort level of healthy volunteers will also be assessed using a satisfaction questionnaire.

Read the detailed description
  • 10 participating sonographers will be recruited from SGH and SKH to perform abdominal ultrasound scanning.
  • 10 healthy volunteers of average body habitus with BMI <30, abdominal circumference <102cm will be recruited.
  • Each sonographer will be randomly assigned to scan 1 healthy volunteer. The same volunteer will be scanned twice with an interval of at least 1 month between two scans: once using conventional abdominal ultrasound scanning procedure and once using ROBUST.
  • During the session, markers coated with a retroreflective material to reflect light to the motion capture camera will be pasted on participating sonographers on various parts of the upper limb.
  • Surface electromyography (sEMG) electrodes will be affixed on sonographers' upper trapezius, deltoid, biceps, triceps, wrist extensors and flexors to monitor muscle activities.
  • The healthy volunteer will lie on a plinth with the participating sonographer seated next to him/her. The sonographer will then perform scanning on various abdominal organs following the point of reference and scanning approach as indicated.
  • The same ultrasound scanner and probe type will be used on all volunteers by all sonographers.
  • Static bilateral grip strength of participating sonographers will be measured using a dynamometer before and after each scan.
  • At the end of both scans, participating sonographers will be required to complete a survey on comfort level.
  • At the end of both scans, healthy volunteers will be required to complete a survey on satisfaction level.
  • The quality of the images from both scans will be rated by 4 readers: 2 consultant radiologists and 2 senior radiographers. A photometer will be used to ensure all readers interpret images directly from a designated monitor under consistent lighting condition.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Comparison of quality of ultrasound image for manual scanning and robot scanning

    Measured: During the scan

  2. Kinematic data, Range of Motion from motion capture system

    Measured: During the scan

  3. Muscle activation from EMG data

    Measured: During the scan

  4. Static bilateral grip strength

    Measured: Immediately before the scan and immediately after the scan

  5. Questionnaire on comfort level from sonographers

    Measured: immediately after the scan

  6. Questionnaire on Satisfaction level from healthy volunteers

    Measured: immediately after the scan

Questions about this trial

What is this clinical trial studying?

An observational study of Work-related Musculoskeletal Disorders, run by Singapore General Hospital at 2 sites in Singapore.

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 4 inclusion and 4 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 12 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Singapore. 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?

Comparison of quality of ultrasound image for manual scanning and robot scanning (time frame: During the scan). The study lists 6 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 12 Aug 2021.
