what are the four components of the Nagi Model?
Pathology → Dysfunction → Functional Limitation → Disability
what is impairment? what are some examples?
impairment is synonymous with dysfunction
examples: decreased ROM, decreased strength
what is tissue impairment? what are some examples?
more detailed than impairment, but less specific than tissue-specific impairments
examples: torn muscle (causing decreased ROM), weak rotator cuff muscles
what is tissue-specific impairment (TSI)? what are some examples?
reference impairments to the actual tissue that is involved and the side of the body the pathology is located
examples: partial tear of the left supraspinatus muscle, weakness of the right infraspinatus muscle
can swelling be considered a tissue-specific impairment?
never, swelling is only considered an impairment
what is swelling inside the joint called?
effusion

- warmth and swelling is commonly present
- pain can be present, but the pain is improving
what classifies an injury as displaying chronic behavior for the state of condition?
- the condition is stable
- warmth is absent
- typically pain has resolved
what classifies an injury as displaying a chronic condition for the state of condition?
- signs or symptoms have become persistent well beyond a tissue full healing
- might have swelling, but no active inflammation
- majority of tissue has healed, but maybe not properly
what are the time frames for healing?

- Proliferation: 2 weeks - 1-2 months
- Remodeling: anytime greater than 1-2 months
what stage of condition is someone considered to be in after immobilization?
sub-acute
what are the therapeutic goals of an injury presenting with acute behavior?
prevent the condition from worsening; decrease the swelling, pain, and protect the injured area
what are the therapeutic goals of an injury presenting with sub-acute behavior?
continue to facilitate the healing process; tissue is still fragile and must be treated delicately as to not cause re-injury and result in the patient digressing back into an acute stage
what are the therapeutic goals of an injury presenting with chronic behavior?
restore the tissue back to normal; during this stage you can begin “fixing” the problem
what are the therapeutic goals of an injury presenting with chronic condition?
determine why the patient has persistent signs/symptoms despite healing being complete
what is tissue reactivity?
how irritable the tissue is; delicate tissue will present with pain
what are the three classifications of tissue reactivity?
(1) High - pain is present before an end-feel can be reached, or resistance of tissue
(2) Moderate - able to determine end-feel and the patient complained of pain
(3) Low - able to determine end-feel with no pain
how is tissue reactivity determined?
by applying a tensile load to the tissue; MUST BE A PASSIVE STEP
determining tissue reactivity must be a passive or an active step?
PASSIVE
If a patient reported pain during the performance of MSTT would you continue on and perform MMT?
no; if you have pain during a sub-max contraction, pain will obviously be present during max contraction
what are the three classifications of subject reactivity?

what is involved with preparatory treatment interventions?
heat could be used before stretching, CP to decrease swelling, mobilizations to decrease joint viscosity, therex @ 50% 1-RM to increase blood flow, etc.
what SOC would heat NOT be used as a modality?
acute SOC; you don’t apply heat to active inflammation
what is a corrective treatment intervention defined as?
this is the treatment that attempts to actually “correct” or “fix” the impairment (ex. strengthening to correct a weakness, or joint manipulation grades III or IV to correct a capsule tightness)
what is one of the most important corrective interventions that EVERY patient should receive?
patient education; you MUST always educate the patient in something specific to them
what is involved with corrective treatment interventions?
typically some form of exercise; (ex. consider that coordination exercise (60% of 1 RM/25-30 reps) is necessary for tonic muscles, whereas, strength exercise (80% of 1 RM/ 10 reps) is necessary for phasic muscles
what is a supportive treatment intervention defined as?
all activities the patient performs to “support” the purpose behind treatments incorporated within the Palliative, Preparatory and Corrective treatments
what is involved with supportive treatment interventions?
