What does MOI stand for?
Mechanism of Injury
How did the injury occur?
What happens during the on-field assessment?
determine athlete's disposition efficiently
refers to tasks not done in the clinical setting
What happens during the clinical assessment?
secondary survey (HOPS)
Definition of palpation
the art of seeing with your hands
Active Range of Motion
always done first
joint motion produced by patient contracting muscles
Passive Range of Motion
clinician moves the joint through the ROM
arthrokinematics - "joint play"
: to flex glenohumeral joint (osteokinematics), the humeral head must slide inferiorly (arthrokinematics)
RROM Measurement Techniques
isotonic = with weights
isometric = with dynamometer
isokinetic = with specific controlled speed dynamometer
muscles acting in their synergies to produce force, stabilize or reduce force
Length Tension relationships
optimal force at optimal length (shortened and elongated alter function)
overactive or tight agonist will inhibit the antagonist
synergist attempt to assume the role of the agonist to produce movement and force
