What does MOI stand for?
- Mechanism of Injury
- How did the injury occur?
What happens during the on-field assessment?
- primary survey
- determine athlete's disposition efficiently
- refers to tasks not done in the clinical setting
What happens during the clinical assessment?
- secondary survey (HOPS)
- professional documentation
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"
- ex: 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
