Title: Musculoskeletal Injuries

Musculoskeletal Injury Facts
  • In the field of sonography, musculoskeletal
    injuries affect approximately 80 of the
  • One of every five sonographers (20) is affected
    by a career ending injury.
  • The average time a sonographer is working in the
    profession before experiencing pain is
    approximately five years.
  • Many sonographers do not report their pain
    because the feel nothing can be done to improve
    the situation.

Musculoskeletal Injury Terms
  • Musculoskeletal injuries among sonographers have
    been described with many terms
  • Work-Related Musculoskeletal Disorder (WRMSD)
  • Musculoskeletal Disorder (MSD)
  • Musculoskeletal Injury (MSI)
  • Repetitive Strain Injury (RSI)
  • Cumulative Trauma Disorder (CTD)

Physical Demands
  • Sonographers must have full use of hands, wrists,
    and shoulders and they face many physical demands
    such as the following
  • Lift more than 30 pounds
  • Push and pull
  • Bend and stoop
  • Work standing on their feet at least 80 of the
  • Assist patients on and off examining tables

Risk Factors
  • Three primary risk factors that contribute to
  • Posture
  • Force
  • Repetition
Description of Exposure
  • Repetitive motion
  • Forceful and awkward movements
  • Persistent continual pressure for long durations
  • Poor posture and body mechanics
  • Improper positioning
  • Excessive force and strain
  • Increased exam scheduling

Causes of WRMSD
  • How does a musculoskeletal injury occur?
  • Basically, thousands of forceful, awkward and
    repetitive movements eventually produce trauma to
    muscles, tendons and ligaments which leads to
    pain, inflammation, swelling and deterioration of
    tendons and ligaments.
Common Work-Related Injuries To Sonographers
  • Shoulder (Rotator Cuff)
  • Elbow
  • Neck

  • Pain
  • Clumsiness
  • Numbness
  • Burning or tingling
  • Tenderness
  • Swelling
  • Loss of sensation
  • Loss of function
  • Muscle spasm
  • Muscle Weakness
Tasks That Aggravate Musculoskeletal Symptoms
  • Applying pressure with the transducer
  • Shoulder abduction
  • Sustained twisting of the neck trunk
  • Repetitive twisting of the neck trunk
  • Performing portable exams

Consequences of WRMSD
  • Decreased and painful work activities
  • Decreased and painful home activities
  • Decreased and painful recreation activities
  • Absent from work
  • Redesign of work station
  • Specialized equipment
  • Fewer work hours
  • Change in profession
  • Physical disability

Raising Awareness
  • Often, the risk for WRMSD is not the result of
    the work be performed, but rather how it is being
  • By increasing awareness of ergonomics, current
    and future sonographers can learn preventative
    measures associated with work-related injuries.

Scanning Ergonomics
  • Sowhat are ergonomics?
  • In general, ergonomics is the science or study of
    how people are affected by their work
  • Ergonomics help adapt and adjust products, tasks
    and environments to people to help reduce
    musculoskeletal disorders and workplace injuries.
  • The most effective control measures to help
    prevent WRMSD include sonographer work methods
    and changes in workstations.
  • Prevention of WRMSD requires a combination of
    changes involving sonographers, department
    managers and equipment manufacturers.
Recommendations To Reduce Risk
  • Recommendations to reduce risk should include the
  • Engineering controls - proper equipment and
    workstation design and layout
  • Administrative controls work organization and
    work practices
  • Individual controls risk identification and
    control, training and education

Sonographer Awareness
  • Sonographers should learn the following
  • Be aware of activities that cause pain and learn
    to modify those activities.
  • Learn the proper use of all exam room equipment.
  • Utilize adaptive equipment when scanning, such as
    support cushions.
  • Learn to perform stretching and strengthening
    exercises designed to prevent injury.

Sonographer Work Practices
  • Decrease the duration of static posturing by
    varying postures throughout the day.
  • Decrease hand grip pressure loosen grip on the
    transducer, take short breaks, vary grip used on
    the transducer.

Sonographer Work Practices
  • Minimize awkward and extreme postures.
  • Increase muscle tissue strength and tolerance to
    injury through exercise and adequate rest.

Musculoskeletal Checklist
  • Is the patient close enough to me? Is my arm and
    elbow tucked in closely to my body in a
    comfortable position.
  • Did I adjust my chair or examination bed
    according to the body habitus of my patient in
    relationship to my height.
  • Is my posture a comfortable and correct so as not
    to cause stress on my body?
  • Am I working with my wrist and neck in a straight
    and supported position?
  • Is the monitor and keyboard positioned so that I
    can easily see and reach them?
  • Am I supporting my limbs properly throughout the
    entire examination?
  • When I stand, am I carrying my body weight
    equally on both feet?
  • Did I take a short break? Did I consciously
    release tension on the scanning hand for a few
  • Did I take a longer break? Did I remove the
    probe from the scanning hand, stretching the
    hand, arm and shoulders.
  • Am I aware of any unusual symptoms, such as
    numbness, swelling or pain?

Musculoskeletal and Physical Affects From
Transducer Use
3D/4D OB Transducer
2D OB Transducer
Musculoskeletal and Physical Affects From
Transducer Use
Heavy, inflexible transducer cables put
additional strain on the wrist, forearm and elbow
of the scanning arm requiring increased grip
force to resist the torque created by the
transducer cable.
