select the best option.
repetitive motions
vibration
prolonged periods of localized pressure
neutral postures
if you need to review this content, it can be found in the effects of repetitive motion, localized pressure, and vibration module of the ergonomics topic.

Explanation:

Using a pipette frequently involves performing the same hand - arm movements repeatedly. Repetitive motions can lead to musculoskeletal disorders over time. Vibration is not typically associated with pipette use. Prolonged periods of localized pressure would involve constant pressure on a body part (e.g., leaning on an elbow), which is not the case here. Neutral postures are actually a good ergonomic practice and not a risk factor.

Answer:

Repetitive motions
