Study Notes
Body Mechanics and Mobility
- Body mechanics involve using proper physical coordination of bones, joints, muscles, and the brain during movement.
- Correct body mechanics help healthcare providers avoid musculoskeletal injuries and fatigue while reducing the risk of patient injury.
Principles of Body Mechanics
- A low center of gravity can be maintained by flexing hips and knees rather than bending at the waist, promoting balance and even weight distribution.
- A wide base of support is created by spreading the feet apart, providing lateral stability and lowering the center of gravity.
- Proper body alignment is crucial; keeping the center of gravity over the base of support is essential, and this is achieved by moving feet instead of twisting and bending at the waist.
Patient Positions
- Erect Position: Patient is upright with their back against the receptor; chin raised to avoid being in the image field.
- Supine Position: Patient lies horizontally with the face upward.
- Dorsal Recumbent Position: Patient lies on their back with lower extremities moderately flexed and rotated outward.
- Fowler Position: Patient is seated in a semi-sitting position at 45–60 degrees, often categorized as high Fowler, Fowler, or low Fowler based on the angle of elevation.
- Lateral Position: Patient lies on their left or right side.
- Prone Position: Patient lies face down.
- Sims Position: A variation of the lateral position, often used for certain medical procedures.
- Knee-Chest Position: Patient brings knees to the chest, enhancing access to the rectal area.
- Trendelenburg Position: Patient’s feet and legs are elevated above heart level while lying supine, often used in emergencies.
- Reverse Trendelenburg Position: Patient lies supine at a 30-degree incline, with the head elevated above the pelvis and legs lower than the hips.
