The anatomy of your low back contributes to spine stability when you lift.
- Spine stability is maximized by using the neutral, power position of the back.
- The TLF (thoracolumbar fascia) helps keep the back in neutral and augments the power generated by the back muscles
- The multifidus and TA (transverse abdominal) muscles coordinate their actions to grip and hold and to guide and control the spine as you lift.
- Bending at the hips and knees helps keep your spine in the power position for lifting.
Give your back an added advantage whenever you lift.
- Lower your center of gravity by keeping your feet apart.
- Keep the load you are lifting close to your body.
- Avoid positions where your back is twisted or bent as you lift.
Keep the eight rules of lifting in mind whenever you must lift.
- Plan and prepare.
- Use a wide base of support.
- Keep the load close.
- Use the neutral spine position.
- Engage your core muscles.
- Lift with your legs.
- Avoid twisting.
- Get help if needed.
Lifting belts are not supported by modern research.
- Scientists still haven't proven that lifting support belts reduce the chances of injury.
- Lifting belts should not be relied upon to protect against back injuries in the workplace.
- They may be of some help for patients who've had an episode of back pain or injury and who are returning to jobs that involve heavy and repeated lifting.
- Reliance on a lifting support belt can cause the trunk muscles to weaken.
Lifting support belts have several drawbacks.
- They can create a false sense of security.
- They haven't been proven to remind workers how to keep their backs lined up for lifting.
- They can cause atrophy and weakness in the back and abdominal muscles.
- Worn improperly, they heighten the risk for back injury.
- People can become psychologically dependent on them.
Lifting becomes a risk factor for back pain only in certain conditions.
- When the lifter uses poor technique.
- When loads of unexpected or unknown weights are lifted.
- When lifting has to be repeated, especially with loads over 50 pounds.
Other factors also make lifting a risk for back pain.
- Abusing tobacco.
- Being overweight.
- Feeling stress about work.
- Feeling dissatisfied with your job.
- Worrying that you'll get hurt lifting at work.
