Types of polyploidy There are mainly two types of polyploidy-autopolyploidy and allo(amphi)polyploidy. There are various types under each of these major divisions. 1. Autopolyploidy is the presence of multiple sets of chromosomes derived from a single genotype.
The two most popular tests for shoulder impingement are the Neer test and the Hawkins test. In the Neer test (below left), the examiner stabilizes the scapula while passively elevating the shoulder, in effect jamming the humeral head into the acromion. In the Hawkins test (below right) the examiner elevates the arm to 90 degrees of abduction and forces the shoulder into internal rotation, grinding the cuff under the subacromial arch.
Test Movement. In the starting position the examiner forcefully moves the patientâs shoulder into internal rotation to the end or range of motion or until reports of pain. Positive Test. The Hawkins Kennedy test is considered positive if pain is reported in the superior â lateral aspect of the shoulder. Accuracy of Test. The Hawkins Kennedy test for shoulder impingement is commonly believed to be less accurate test for shoulder impingement than the Neer test though some studies have found the reverse to be true.
