| Valgus Stress (Elbow) at 00  | 
              
                | Examination type | Ligament Laxity, Joint Instability | 
              
                | Patient & Body Segment Positioning | The patient 
				is sitting upright, with elbow fully extended (0 degrees).  
				Patient does not resist or assist any movement. | 
              
                | Examiner Position | The examiner 
				should face the patient while standing on the side of the 
				affected elbow with one hand cupping the elbow (heel of hand on 
				lateral side of elbow with fingers on medial side) for support 
				while the other hand is placed at the patient’s wrist to provide 
				force. | 
              
                | Performing the Test | Cup the 
				posterior aspect of the patients elbow in one hand and hold the 
				patients wrist in the other.  The hand on the elbow will act as 
				a fulcrum around which the examiner’s other hand will apply.  
				With the elbow extended to 0 degrees, force the forearm 
				laterally which will place stress on the medial side of the 
				elbow. | 
              
                | Tissues 
            Being Tested | Ulnar collateral ligament | 
              
                | Positive Test | Lack of a 
				firm end feel or extra joint opening as compared bilaterally | 
              
                | Interpretation | Possible 
				sprain (stretching or even tear) of the ulnar collateral 
				ligament | 
              
                | Common errors in 
            performing exam | Not placing 
				enough force on the elbow; not completely extending the 
				patient’s elbow to 0 degrees; not comparing bilaterally | 
              
                | Factors possibly 
            resulting in misinterpretation | Athletes who 
				routinely participate in repetitive overhead activities, such as 
				baseball pitchers, may show excess laxity in the dominant arm 
				even with no injury to the ulnar collateral ligament. |
