Flex Therapist CEUs

1. There is virtually no bending moment resisted by the spinal discs and ligaments when the lumbar spine is flexed to what percent?

A. 20% B. 40% C. 80% D. 100%

2. The recruitment of passive tissues of the lumbar spine during flexion does not tend to result in a change in spinal compression forces.

A. True B. False

3. When lifting with a lordotic posture, the upper erector spinae and lumbar erector spinae show similar activation patterns. At the initiation of the lift both the upper erector spinae and lumbar erector spinae activation peak and there is minimal change in lumbar curvature. This would suggest that the primary action of the erector spinae during the initial stages of a lift is:

A. Isometric B. Concentric C. Eccentric D. None of the above

4. There seems to be strong biomechanical evidence to suggest that end range of lumbar flexion during lifting and lowering should be avoided. It could be argued that this is not just a matter of instructing patients to 'bend the knees,' as patients who use a bent knee technique can still flex their lumbar spine to maximum range.

A. True B. False
