1	"Kansas State University" Kansas State University Division of public safety
2	"Lever Arms and Lifting" Lever Arms and Lifting Basic understanding of the spinal column Functions of the disc Bending – Twisting – Loading Keys to safe lifting Get a grip!!!
3
4
5	"Daily stress to the body" Daily stress to the body When exposed to high risk activities If stress > bodies ability to recover Result is inflammation Long term exposure = cumulative trauma
6	"Repetition" Repetition Forceful exertion Awkward and/or sustained postures Mechanical Stress
7
8	"Prevention" Prevention Early Intervention Training Implementation Eyes on the floor Feedback
9
10	"Review of the anatomy" Review of the anatomy normal curves bony columns function of the disc spinal cord & nerve roots degenerative issues Maintain the balance
11
12
13	"Posterior column of support" Posterior column of support made up of the facet column very stable reflects an upright posture Anterior column of support made up of body of vertebra and the disc less stable reflects a flexed posture
14	"The disc is the shock..." The disc is the shock absorber of the spine 85% water at the age of 15 25% water at the age of 75
15
16
17	"Too much spinal flexion" Too much spinal flexion loads the anterior column of support places the posterior wall of the disc at risk has the potential for nerve root compromise
18
19
20	"Avoid excessive flexion of the..." Avoid excessive flexion of the spine Flexed postures increases your risk of disc and nerve root involvement Maintain up-right postures - not back bends... Think posture
21	"Up-right neutral posture" Up-right neutral posture Posterior column of support Stable = less risk of injury
22
23	"Lying flat:" Lying flat: disc pressure equals 25 psi Standing: disc pressure equals 100 psi Sitting erect: disc pressure equals 100 psi Sitting slouched: pressure equals 150-175 psi Lifting 25# box from the floor in a flexed posture: disc pressure equals > 400 psi

32	"Tendon function:" Tendon function: transmit force from muscle to bone Micro tears of tendon occur daily Typically repair themselves With repeated loading repair is not adequate Pain / Inflammation
33	"Required physical effort" Required physical effort Type of grip Object weight Distribution of weight Object dimension Required posture Duration of effort
