Which strategies are described as part of ergonomics and spine-sparing in reinforcement?

• A. Movement modifications and ergonomics
• B. High-fat diet
• C. Ignoring posture
• D. No change in activity

Answer: (A)

Movement modifications and ergonomics focus on how you move and the environment to protect the spine during reinforcement. By adjusting lifting techniques, keeping loads close to the body, maintaining a neutral spine, bending at the hips and knees rather than at the back, and avoiding twisting, you reduce bending and shear forces on the lumbar spine. Pair these with ergonomic adjustments—properly positioned work surfaces, supports, and assistive devices, plus pacing tasks—to promote safer mechanics throughout activities and rehab. These combined strategies directly reduce spinal load and support safer reinforcement. The other options don’t provide this protective approach: a high-fat diet isn’t a mechanical safeguard, ignoring posture increases risk, and no change in activity would hinder spine-protective progress.
