“…body mechanics, is still the foundation of many of the educational programs…despite the technological, scientific, and evidence-based revolution...”
Audrey Nelson, Safe Patient Handling and Movement

• “We used to work on ultrasound machines and 90 percent of sonographers would end with lost time injuries on their shoulders over time.
• “It was just because they were badly designed machines.”– Nancy Paris, Director of PART, BCIT

Injuries In Sonography
• Injuries using ultrasound:– More than 80% scanning in pain– 20% of above – career ending injury– Onset of pain within 5 years– Other

Body Mechanics/Basic Ergonomics
• Well identified.
• Consensus Conference (WRMDS)– Equipment Control Measures– Administrative Control Measures– Professional Control Measures
• Very little help.

Cardiac Sonography
• Pain in shoulder, wrist and thumb.
• Caused by trying to get image.
• Require more force for larger patients.
• Prolonged scans.• Administrative controls.• WCB ergonomic
recommendations.

The Problem
• Peak pinch force injury (thumb/wrist)– 10 Newtons (approx 0.45 kg)
• Push forces (female) at 6 seconds:– 11-14 kg– Less for sustained forces

The Problem
• Biomechanical Model– Cannot reduce forces appropriately.– Forcing the employee to fit the machine.
• Ergonomics– Try to get the machine to fit the worker.

Possible Solution
• Introduce to NSCC Engineering.– Dan Bolivar, Faculty NSCC– Three Engineering Students
• Alan Lock• Ben Bates• Coady Carter
– Project to reduce overall forces.– Eventually, Karen Richards, ergoCentric
