CERVICAL and THORACIC SPINETESTS
Tests for topical diagnosis of the cervical and thoracicspine
Movementstesting
The movement tests design to evaluate the involvement in the pathological process particular muscles, nerves and nerve roots. The examiner should not only to conduct the tests but also observe how the patient executes the particular movements. These tests can help localize a lesion to the particular cortical or white matter region, spinal cord level, nerve root, peripheral nerve, or muscle. Movement tests quantify by using muscle strength (MS). All tests and movements testing in particular depend on the patient’s cooperation and sufficient efforts. If the patient consciously or unconsciously unable to cooperate, the examiner should document “insufficient efforts” and try to observe and appreciate MS indirectly. For example, observe the patient’s ability to put on/ takes off clothes, lace shoes, fasten buttons and zips and write/ type on a computer during fill out the office papers. The examiner may quickly test of the upper extremity movements analyzing muscle strength of the certain muscles. Testing of the strength of each muscle group should be performed in a consistent uniform order. The examiner should test symmetrical muscles started with the dominant extremity. MS is rated on a scale of 0/5 to 5/5:

BakodySign
Indications: suggestive for the cervical radiculopathy at the levels of C4-C6. Test is indicative for the nerve root irritation due to cervical foraminalcompression.
Patient’s position: sittingupright.
Technique: Either the patient actively, or the examiner passively, place the patient’s hand on top of his/herhead.
Interpretation: the test is positive if the patient reports decrease pain.
Clinical Notes: Reverse Bakody Sign can be noted when the patient resists raising the arm and hand toward the head. This finding should be correlated with other orthopedic testing, as it could indicate facet irritation, glenohumeral dysfunction, rotator-cuff trauma or myofascialspasm.
