| Term | Definition |
| body mechanics | safe and efficient use of the body using scientific reasoning based on kinesiology and physiology |
| goal of body mechanics | conserve energy, decrease stress & strain, prevent injury |
| forces | gravity & friction |
| center of gravity (COG) | point where mass is equally distributed |
| base of support (BOS) | part of object in contact with support surface |
| line of gravity | perpendicular line thru COG & BOS |
| ways to improve stability | 1)decrease COG 2)centralize COG over BOS 3)increase size of BOS 4)increase weight |
| other rules | every action has equal and opposite reaction/ increase mobility-decrease stability & vice versa |
| COG in the body | about S2 in adults |
| BOS in body | changes according to position |
| anatomy of disc | nucleus populous-soft / annulus fibrosus-tough |
| purpose of disc | gives mobility & acts as shock absorber & flexibility |
| imbibing | fills with fluid at night |
| area of the disc @ risk for injury with flexion | posterior |
| area of the disc @ risk for injury with extension | anterior |
| area of the disc @ risk for injury with flex/rotation | posterior/lateral |
| lever system | weight of object + upper body X 10 |
| dynamic support | trunk muscles are like a corset |
| when lifting... | use legs |
| sprain | soft tissue injury to joint |
| osteoarthritis | wearing out/may cause bone spurs |
| mm strain | tearing of muscle |
| types of disc injury | tearing, bulging, rupture, herniation (HNP) |
| forces causing back injury can be... | prolonged forces, repetitive, or could be one time big thing |
| laminectomy | removal of part of bone or disc |
| discectomy | removal of whole disc |
| fusion | vertebrae fused together |
| increased lordosis... | caused by anterior pelvic tilt, lumbar ext, hip flexors |
| decreased lordosis... | caused by posterior pelvic tilt, abs, hip extensors (glut. max) |
| pelvic tilt is determined by... | the movement of the anterior superior iliac spine (ASIS) |
| lateral plumbline | thru ear, thru acromium, just posterior to hip joint axis (greater trochanter), just anterior to knee axis, just anterior to ankle axis (laterl malleolus) |
