189
stretching and tissue properties - 2
toe is where everyone goes
has to go through plastic for permanent deformation - PNF - passive to barrier (passive restraint) then you keep going and get past it - compensation from the body and scream and push back but hold for 10 seconds and repeat till no slack - you have to hurt a little
190
does static stretching increase flexibility?
no
191
slow vs fast load
fast much more dangerous and forceful
192
load

198
5 primary tissue stresses leading to injuries
tension, stretching, compression, shearing, bending
199
tension
force that pulls or stretches tissue
200
stretching
when go beyond yield pt leads to rupturing of soft tissue or fracturing of bone
201
compression
large force that crushes tissue
202
shearing
force that moves across in a parallel fashion across tissue - muscle is okay but bone will break
203
bending
force on a horizontal axis that places enough stress to cause the structure to bend
204
acute injuries and 6 examples
within 3 days- some sort of healing and it was an event - sudden and traumatic
contusions, sprains, strains, dislocations, subluxations, fractures
205
contusions - 6
MOI
What happens
bruise
external force causes soft tissues to be compressed against hard bone
capillaries may break and cause bleeding into the tissues which accumulates under the connective tissue
deep contusions can bruise the bone
pain improves within a few days and discoloration decreases with a few weeks
muscle pain with active contraction
206
myositis ossificans
MOI
What happens
dont take care of the inflammation - you need to pad and let it heal
occurs when a muscle or soft tissue is bruised repetitively
ca begins to deposit in muslce fibre - blood pooling and ph changes
may impact movement
207
Treatment of myositis ossificans
usually surgical intervention is needed

283
3 phases of healing process
inflammatory (hemostasis) response - 0-4d
fibroblastic repair 1-inf
maturation - remodeling 2-inf
continuum - overlap and have no set/end pt
284
goal of you during healing process
create an environment that is conducive to the healing process
285
When does inflammatory begin
what does it result in?
duration?
once tissue is injured - direct injury to cells of soft tissue
Release of materials needed for the inflammatory response
2-4 d - ice in 72 hrs
286
purpose of inflammation - 2
protect/splint, localize and rid body of some injurious agent in prep of healing
associated with vascular, cellular and chemical responses
287
Why is the inflammation phase critical?
if it does not accomplish what is needed/does not subside, normal healing cannot take place
288
Symptoms of inflammatory response
```
Swelling
Heat
Altered function
Redness
Pain
```
289
2 events of inflammatory phase
vascular reaction
| formation of a clot
290
vascular reaction - 2
vascular spasm - vasoconstriction of vascular walls to reduce blood flow (5-10min - ice, tensor, immob), followed by vasodilation
formation of a platelet plug, blood coagulation, and growth of fibrous tissue
chemical mediators released - histamine, leukotaxin, necrosin to limit amt of exudate and swelling, swelling depends on the extent of tissue damage
291
formation of a clot - 3
damage to BV exposes the endothelium and collagen fibers
platelets and leukocytes adhere to the exposed fibers, eventually forming a plug
localize the injury process
292
Fibroplasia
Period of scar formation
293
Fibroblastic phase
time frame
S&S- 2
formation of scar
first few hours and up to 4-6 weeks
inflammatory S&S subside
tender to touch and painful with certain movements - depends on the tissues diff peak points
294
What is happening in fibroblastic phase - 2
new capillaries bud into wound to deliver oxygen - increase blood flow and nutrients to site - initially a granulation tissue to fill in gaps
as healing continues fibroblast accumulate at the would site and synthesize new extracellular matrix that contains collagen, elastin, ground substance and additional proteins
295
day 6-7 of fibroblastic - repair phase - 3
collagen fibers deposited in a random fashion, forming a scar
tensile strength increases in proportion to the rate of collagen synthesis
increase in tensile strength decreases fibroblast production to begin next phase
296
Maturation-remodeling phase - 5
long term - up to several yrs
realignment or redeling of collagen fibers that make up the scar tissue and ongoing breakdown and synthesis of collagen
increased stress and strain causes the collagen fibers to realign along the lines of tension
tissues gradually assume normal appearance and function
by the end of 3 weeks - firm, strong, contracted, non-vascular scar forms
297
Chronic inflammation - 4
acute inflammatory phase does not eliminate the agents and restore tissue to normal state
can last for m to y
repeated microtraumas and overuse of a particular structure
typically resistant to both physical and pharmacological treatments
298
Cartilage healing capability
dependent on whether the damage is to the cartilage or subchrondral bone - bone progresses normally
299
Lig healing capability - 3
normal
fibrin clot helps to bridge the torn ends of the lig
over m scar continues to mature in response to stress and strain - up to 12 m
300
why is lig healing variable - 2
scar tissue is insufficient
| lig not reattached to the proper location on the bone - lig failure
301
3 stages of healing in muscles
in large and force producing muslces - hemorrage, edema, phagocytosis to clear debris
scar formation, myiblastic activity to regenerate myofibrils
maturation - collagen fibers arrange themselves along lines of tensile force - needed for active muscle contraction
302
active muscle contraction is needed for
normal tensile strength
303
Length of rehab in muscles depend on
degree of strain = can be longer than lig sprain
304
Muscle strain and too soon for return to play
reinjury and start healing process again
305
Nerve healing
| process - 3
cells dont regenerate when they die but nerve fibers do
peripheral nerve regeneration at 3-4mm/d
damaged nerves in CNS regenerate very poorly bc they lack CT sheaths and schwann cells dont proliferate
surgical intervention in severed nerve - increases healing potential
306
Bone healing - 3
callus formation needs to occur at the fracture site
remoddling process - ongoing where osteoblasts lay down new bone and osteoclasts remove bone according to the forces placed on the healing bone - wolff's law - bone adapts to the mechanical stress and strain by changing size, shape and structure
osteoblast/clast activity may cont for 2-3 years
307
3 types of trauma to bone
contusion of periosteum
closed nondisplaced fractures
displaced open fractures that involve soft tissue
308
factors that impede healing - 7
```
extent of injury -
edema
hemorrhage
poor vascular supply
infection
separation of tissue
muscle spasm
health, age and nutrition
```
309
extent of injury and healing -2
greater the damage the more inflammation present - microtears vs macrotears
310
edema and healing
increased pressure causes tissue separation, inhibits neuromuscular control and impedes nutrition to the injured structure
311
hemorrage and healing - 3
increased bleeding causes increased pressure, additional tissue damage
if its bleeding its not healing
312
poor vascular supply and healing
poorly and slow - tendons and ligs
313
infection and healing - 2
delays healing and increases granulation tissue
314
separation of tissue and healing - 2
need more scare tissue to fill the gap
| smooth edges vs jagged/separated edges
315
muscle spasm
cause traction of torn tissue, separating the 2 ends, affecting approximation
316
health, age and nutrition - 2
```
older age has less elastic properties of tissue
vit c(collagen synthesis), vit k(clotting), vit A(immune system)
```
317
PIER
pressure - pressure on blood vessels to make it harder for fluid to leak out
ice - vasocontriction therefore reducing swelling
elevation - uses gravity to assist in fluid drainage in area
rest - ceases damage to the area by not placing stress on injured structures
318
Pain - 2
subjective sensation
| unpleasant sensory and emotional experience associated with actual or potential tissue damage
319
Goal with pain
control acute pain by encouraging the body to heal through exercise designed to progressively increase functional capacity and return the patient to full activity as quick and safe as possible
320
acute vs chronic pain
less than 6m vs greater than 6m and cont beyond usual normal healing time
321
referred pain
away from the actual site of irritation
322
How do you treat pain -2
therapeutic modalities and manual therapy techniques
ex: heat, cold, electrical stim, ultrasound, manipulation, ART, massage etc
medication - Physician - NSAIDs or analgesics
323
4 ways to treat pain with therapeutic exercises
exercises/stretches to ROM; helps enhance realignment of scar tissue
exercises to help strengthen injured tissues or surrounding areas
include proprioception
advance to functional exercise
324

328
how to figure out when to use stitches
open it to see deepness and if it goes back together its okay steri strip, if not - get stitches
329
In what environment do cuts heal better in?
moist environment
330
how do you heal chronic inflammation
reset it to square 1
331
stability for a jt after a lig injury
generally pretty good, some are within the jt capsule and gets less blood
332
3 treatments during skeletal inflammatory
