Good Ergonomic Practices
WARNING: The operation of an ultrasound system may to linked to musculoskeletal
disorders (MSDs).
In ultrasound imaging, ergonomics may be defined as the physical interaction between the
operator, the system, and the transducer, in the course of conducting exams. It is important for
the operator of the system to practice good ergonomic techniques to reduce the risk of injury.
This chapter is intended to provide guidelines to help you work more comfortably in order to
possibly reduce the risk of musculoskeletal disorders.
When using an ultrasound system, as with many similar physical activities, you may experience
occasional discomfort in your hands, fingers, arms, shoulders, eyes, neck, back, or other parts
of your body. If you experience symptoms such as constant or recurring discomfort, pain,
throbbing, aching, tingling, numbness, burning sensation, or stiffness, you should promptly
consult a qualified health professional. These may be symptoms of MSD. MSDs can be painful
and may result in potentially disabling injuries to the nerves, muscles, tendons, joints, or other
parts of the body. Examples of MSDs include carpal tunnel syndrome and tendonitis.
Steps you can take to guard against discomfort while scanning, or the risk of MSD are
described here. It is also recommended that you consult the guidelines of professional medical
societies concerned with ultrasound.
Interrupt Scanning
Interrupt scanning frequently, using breaks to rest and give soft tissue a chance to recuperate
from the strained positions and repetitive movements of examinations.
While scanning, avoid maintaining the same body position for extended periods of time, by
moving and varying head, neck, body, arm, and leg positions.
Positioning
Avoid bending or stooping.
Adjust the position of the

not require strained or awkward body positions.
Whenever possible, use an adjustable chair with good back support, and adjust chair height to
promote good body posture. If possible, adjust the height of the patient bed to optimize body
posture.
Maintain a comfortable and balanced body position with minimal stress on your joints,
minimizing bending and twisting.
Keep elbows close to your side and relax your shoulders in a level position.
Hand and Wrist
Do not grasp the transducer with excessive force; hold it as lightly as possible.
Minimize the amount of pressure applied when pressing the transducer against the patient.
Avoid or minimize bending your wrist.
Exercise and Stretching
Targeted exercises and stretching may help avoid the risk of MSDs. Consult with a qualified
health professional to define a program suited to your needs and practices.
