5 - Back Pain Basics - Review
The degenerative model of back pain describes a chain reaction of changes.
- At first the nucleus weakens, tears, and scars.
- As disc height decreases, the vertebrae move closer together.
- This puts pressure on the facet joints, which can cause them to become arthritic.
- Changes in the ligaments, discs, and facet joints can cause the spinal segment to become loose and unstable.
- Bone spurs form on the vertebrae.
- The nucleus may squeeze (herniate) through the weakened annulus
Mechanical pain comes from wear and tear on the parts of the spine.
- It's like a machine that is wearing out.
- It usually gets worse with activity and eases with rest.
- The pain rarely goes down past the knee.
- It usually doesn't cause weakness or numbness.
Neurogenic pain comes from a nerve injury.
- It occurs when spinal nerves are inflamed, squeezed, or pinched.
- It can cause pain and symptoms that affect structures away from the spine.
Neurogenic pain is more concerning than mechanical pain.
- Neurogenic pain involves the spinal nerves and can lead to weakness and numbness in the legs.
- Mechanical pain usually doesn't affect the nerves.
Protect your back while sweeping and mopping.
- Engage your core muscles to keep you from twisting back and forth.
- Keep one leg in front of the other and lean forward and back from your hips.
Sample calculations of the training heart rate for a sedentary
- 220 - 40 = 180 (180 is his maximum heart rate).
- 180 x .6 = 104 beats per minute (bpm).
- He should feel 26 pulses in 15 seconds during exercises (26 x 4 = 104 bpm).
