Define Capsular and Noncapsular Pattern and give an example of each.
Only joints being controlled by muscles can present with a capsular pattern. Painful stimuli from the joint incite involuntary muscle spasms. The muscle spasms cause a restriction of movement at the joint. Every joint capsule resists a stretching in a specific way. A capsular pattern presents as a proportional limitations of joint movements that are characteristic at each joint. The shoulder capsular pattern would look different from the capsular pattern of the hip. A noncapsular pattern exsists when there is a limitation of movement at a joint but does not in a capsular pattern. A noncapsular pattern indicates the absence of a total joint reaction. Extra-articular lesions can result in a noncapsular pattern.
Define close-packed and loose-packed positions of joints.
A close packed position is when the joint surfaces are fully congruent, which places maximal tension in the joint capsule and ligaments. In this position the joint surface cannot be pulled apart with traction. You should avoid a close packed position when muscle testing. A loose packed position is any position of a joint other than the close packed position. A position in which the joint surfaces are not congruent and parts of the joint capsule are lax.
What is the typical range of labral tear for a Bankart lesion and what is a common MOI for a Bankart lesion?
The range of a Bankart Lesion is 3 to 6 (the anterioinferior portion of the labrum). A common mechanism of injury for a Bankart lesion is an anterior dislocation of the shoulder from the glenohumeral joint.
