1.) movement is strong and pain free - muscle and nervous tissue intact and not cause of discomfort 2.) Movement is strong and painful - Local lesion in muscle or tendion (1/2nd degree strain) 3.) Movement is weak and painful - severe lesion around joint - caused by reflex inhibition secondary to pain 4.) movement is weak and pain free - 3 degree strian or neural involvement |
|
Sources of muscular weakness? |
- strain - pain inhibition - peripheral nerve injury - nerve root lesion (myotome) - upper motor neuron lesion - tendon pathology - avulsion - psychological affect |
|
Why palpate? |
can differentiate btw tissue quality - determine joint tenderness - determine variations in temp - note any alterations in sensation or presence of crepitus begin away from injury and move towards |
|
Define trauma?
|
Physical injury or wound produced by internal or external force |
|
What is mechanical injury a result of? |
Force or mechanical energy that changes the state of rest or uniform motion of matter |
|
Common MOIs? |
- all out exertion - contact - striking or throwing projectiles - propulsion of the body through the air - repetition of movement |
|
Load? |
external force acting on body causing internal reactions within tissues |
|
Stiffness? |
Ability of tissue to resist load |
|
Stress? |
internal resistance to load |
|
Strain? |
Internal change in tissue (length) resulting in deformation |
|
Direct impact? |
Injury occurs at the point of impact |
|
Indirect impact? |
injury occurs at point away from contact |
|
what are the 5 types of tissue loading? |
Compression Tension Shearing Bending Torsion |
|
Describe compressive tissue loading |
force that results in tissue crush - aka compression - 2 forces applied towards each other eg. standing, burst fracture of spine |
|
Describe tension tissue loading |
Forces that pulls and stretches tissue eg. ligaments or muscles, hamstring strain |
|
Shearing |
Force that moves across the parallel organization of tissue Stress causing 2 opposing bones that displace one each other eg. Spondylolisthesis |
|
Bending tissue loading? |
4 points- 2 forces act at opposite ends of structure
3 points - 3 forces, 2 on ends and 1 in middle eg. bone |
|
Torsion? |
twisting in opposite direction from opposite ends twisting force that causes tissue to fail eg. ACL |
|
When does an injury become chronic? |
When it doesnt heal properly |
|
Impingement? |
Pinching of intervening tissue btw 2 bony structures eg. subdeltiod bursitis |
|
Friction? |
Reptitive frictino btw 2 structures or an intervening structure (bursa) eg. illiotibial band friction syndrome |
|
injuries are classified according to what? |
- Stage of injury or healing - Severity of the injury - Type of tissue damaged/injured - type of mechanism |
|
1st degree muscle strain? |
Some fibers stretched or torn, Full ROM but painful |
|
2nd degree muscle strain? |
multiple fibers torn - active contraction painful - divot is palpable, some swelling and discolouration |
|
3rd degree strain? |
Complete rupture of muscle or musculotendinous junction - significant impairment - great deal of pain |
|
Abnormal muscle contraction is the result of...? |
Failure in reciprocal coordination of agonist and antagonist Electrolyte imbalance due to sweating or strength imbalance |
|
Muscle gaurding? |
muscles within effected area contract to immobilize area to minimize pain - involuntary muscle contraction |
|
What is a clonic and tonic muscle spasm? |
Clonic- alternating involuntary muscular contractions and relaxations in quick succession Tonic- rigid contraction that lasts a period of time |
|
What is a contusion? |
Bruise that results from a sudden traumatic blow that compresses the soft or boney tissues - creates hemorrhaging - chronically inflamed and contused tissue may result in generation of calcium deposits (myositis ossificans) |
|
Tendinitis? |
tenderness due to repeated microtrauma and degenerative changes - inflammation of tendon RESTTTT |
|
Tendinosis/tendonopathies? |
due to improper healing of tendinitis - visibly swollen with stiffness and restricted motion |
|
Tenosynovitis? |
inflammation of synovial sheath Acute- rapid onset, crepitus and diffuse swelling Chronic - thickening of tendon with pain and crepitus often occurs in flexor tendon of digit and biceps tendon |
|
How does a ligamentous sprain occur? |
Traumatic joint twist that causes stretching or tearing of connective tissue |
|
Grade 1 sprain? |
Some pain, minimal loss of function, no abnormal motion, mild point tenderness |
|
Grade 2 sprain? |
Pain, moderate loss of function, swelling and instability with tearing and separation of ligament fibers |
|
Grade 3 sprain? |
Extremely painful - loss of function - severe instability and swelling |
|
Subluxation? |
Breif, transient injury involving partial dislocation and spontaneous joint relocation |
|
Dislocation? |
disarticulation of joint - stablizing structures of joint are disrupted - common in fingers and shoulder |
|
Separation? |
separation of fibrous joint due to stretching or tearing of supporting tissues |
|
Bone fracture S&S? |
S: deformity, pain, point tenderness, swelling, pain on active and passive movements |
|
stress fractures? |
overload due to muscle contraction, altered stress distribution due to muscle fatigue, changes in surface |
|
3 types of bone fractures? |
linear - line parallel to bone transverse- line perpendicular to bone spiral oblique |
|
3 major stages of healing? |
1. inflammatory phase: 1-4 days 2. fibro-plastic repair phase : 3 days- 6 weeks 3. maturation- remodeling phase: upto 3 years |
|
Goal of leukocytes and phagocytic cells? |
- protect - localize - decrease injurious agents - prepare for healing and repair |
|
inflammatory phase is characterized by SHARP. What does sharp stand for |
- swelling - heat - altered function - redness - pain |
|
Process of clot formation? |
injury to cell -> chemical mediators liberated -> vascular reaction -> platelets and leukocytes adhere to vascular wall -> phagocytosis |
|
What does histamine do? |
First to arrive at wound - causes vasodilation and changes cell permeability owing to swelling |
|
Chemical mediators? |
- impact adherence along cell wall - increase permeability locally for fluid and protein passage - facilitates exudate formation and neutrophil entrance to injured site |
|
vascular response of inflammatory phase |
- vasocontriction, coagulation - chem mediators are released - vasodilation later |
|
3 stages of clot formation? |
1. thromboplastin is formed 2. prothrombin is converted to thrombin due to interaction with thromboplastin 3. thrombin changes from soluble fibrinogen to insoluble fibrin coagulating into a network localizing the injury |
|
What ends the inflammatory stage? |
Fibrin clot: Leukocytes phagocytize the remaining debris |
|
What causes chronic inflammation? |
Occurs when acute inflammatory response does not eliminate injuring agent - tissue not restored to normal physiologic state |
|
How does the fibroblastic repair phase begin? |
Commences when macrophages have finished - cap buds begin to proliferate - reactino to hypoxia - create revascularization |
|
What signals the beginning of stage 3? |
tensile strength increases, fibroblastic activity slows |
|
Maturation and remodeling is characterized by..? |
Remodeling of scar tissue according to tensile forces - tissue will gradually assume normal appearance |
|
What should u do actively during the remodeling phase? |
Controlled activity should be added - work towards regaining normal flexibility and strength |
|
Factors that impede healing? |
- extent of injury - edema - hemorrhage - poor vascular supply - separation of tissue - muscle spasm - atrophy - infection - health, age, nutrition |
|
Tell me about cartilage healing boi |
- Limited capacity to heal - little or no direct blood supply |
|
Tell me about dat ligament healing my n*gga |
similar to vascular tissues, 3 phases - repair will involved random laying down of collagen which will mature and realign in reaction to joint stresses and strain |
|
What types of factors affect the healing of ligaments? |
- surgically repaired ligaments r stronger due to decreased scar formation - exercised ligaments r stronger as opposed to immobilized |
|
what is required for good tensile strength of tendon healing? |
an abundance of collagen - initially injured tendon will adhere to surrounding tissues |
|
5 stages of acute fractures? |
- hematoma formation - cellular proliferation - callus formation - ossification - remodeling |
|
short term goals of injury rehab? |
- control pain - maintain/increase flexibility - increase/restore strength - maintain cardiorespiratory fitness |
|
Long term goals of rehab? |
return to practice/competition as quickly and as safely as possible |
|
factors to consider when developing a RTP plan? |
- Mechanism of injury - age - anatomical structures involved - injury severity |
|
Acute management goals? |
Manage injury site - bleeding, pain, inflammation - Prevent secondary complications - support and stabilize injury - implement a home program (RICE, basic ROM) |
|
Effects of cold? |
Vasoconstriction or vessels - decrease blood flow, inflammation, cellular waste production |
|
Hunting response? |
bodys reaction ice when temp reaches 10 degrees - vasodilation followed by vasoconstriction |
|
fibroplastic repair phase goals? |
control pain, reduce swelling - scar is forming and pain is decreasing with active and passive ROM |
|
Goals of maturation and remodeling? |
- Return to activity - collagen fibers need stresses and strains to align - functional training - strengthening exercises |
