Test 3 & 4 Flashcards
Local depolarization of muscle membrane of myofascially involved fibers
LTR - local twitch response
Mechanical pain in joint during myofascial stretching
PSS - positive stretch sign
RPP - Referred pain pattern
activation of trigger point that projects pain to a distant reference zone
TMJ
temporal mandibular joint
Heads & trigger points of SCM
2 heads & 4 trigger points
What do you need to do to treat the Longus Colli
displace the trachea laterally
RPP for Upper Trapezius
up towards the neck and head
3 things to do when treat the TMJ
- Assess their movement - Wear gloves to work inside mouth - Always flush after treatment
Myofascial stretch for Upper Trapezius
flex the neck, side bending to the opposite side, rotation to the ipsilateral (same) side *All of the above
Action of Upper trapezius
elevates scapula
biomechanics of injury for splenius capitis and cervicis
postural stress short repetitive movements of neck
action for masseter muscle
lower jaw closure & clenching of teeth
RPP for Scalene
None of above (actually is neck, pectoral region, border of scapula, front & back of arm, radial surface of forearm, index finger & thumb)
Myofascial stretch for Subocciptal muscles
chin tuck followed by cervical traction
constant or repetitive forward neck bending biomechanical injury for what muscle
SCM
muscles involved in whiplash injuries & high-velocity neck movements
SCM & Scalenes
Muscles affected by asthma & other breathing problems
scalenes
RPP for Splenius Capitis & Cervicis
Top of head, middle of coronal suture, posterior to the suborbital margin, trunk & shoulder
Action of Temporalis
Clenches teeth
Travel & Simmons definition of trigger points
hyper-irritable spot in skeletal muscle associated w/ hypersensitive palpable nodule in taut band. Spot painful on compression & can give referred pain, referred tenderness, motor dysfunction & autonomic phenomena.
Biomechanics of injury for Latissimus Dorsi
Activities requiring repetitive extension, adduction & internal rotation of shoulder (some types of swimming)
PSS for Teres major
pain in the superior Acomion area
Origin & Insertion for Pectoralis minor
Origin - Anterior surface of 3-5 ribs Insertion - Coracoid process of scapula
to myofascially stretch Latissimus Dorsi you must
do shoulder abduction to 180 degrees & external rotation
The positive stretch sign (PSS) of pain in superior acromion area indicates dysfunction in what muscles
- Latissimus dorsi - Teres major - Subscapularis - Deltoid
Biomechanics of injury for Subclavius
Direct trauma & clavicular fracture
Action of Pectoralis minor
raises ribs & forced inspiration
Origin & insertion of Subscapularis
Origin - Subscapular fossa on costal surface of scapula Insertion - Lesser tubercle of humerus & tendon attaches to fibrous capsule of shoulder joint
pain when trying to button a skirt or bra indicates dysfunction in what muscle
Infraspinatus
surrounds each muscle fiber, tendon, bone, nerve & vessel in body
connective fascial tissue
role of sarcoplasmic reticulum
storage of calcium necessary for muscle contraction
functional unit of motor nervous system
motor neuron
3 causes of micro trauma
over shortening over stretching over loading
chemical used as energy source for muscle contraction
ACH
Symptoms associated with myofascial trigger points b/c of nociceptive substances
- Referred pain - Burning sensation - Occasional pain - Tenderness on involved muscle
best explanation of pain
Pain is fear expressed by all living creatures with pain receptors…
components of successful, appropriate, accurate treatment of client
- Treatment done consistently - Method of treatment - hand placement - degree of stretching - position of myofascial stretching
Myofascial trigger point can be found
anywhere w/in muscle belly & pathological mechanism resides in dysfunctional endplates
MTP that produces pain w/o digital compression, tender upon palpation, produces RPP, impedes flexibility, produces muscle weakness, & may elicit LTR is?
Active TP
The consequences of body’s fight against gravity
