			Pivot Shift Test – Lateral Pivot Shift Maneuver 
			Test of 
			Machintosh – Pivot-Jerk Test  | 
              
                | Examination type | Ligamentous Stability | 
              
                | Patient & Body Segment Positioning | Patient should lie supine, and be completely relaxed on the exam 
				table | 
              
                | Examiner Position | The examiner will grasp the patient’s ankle with one hand, and 
				also grasp the lateral side of the leg level with the fibular 
				head. | 
              
                | Tissues 
            Being Tested | Anterior 
				Cruciate Ligament | 
              
                | Performing the Test | Examiner will passively move the patient’s hip into 30 degrees 
				of abduction and flexion. The examiner will then medially rotate 
				the leg slightly. Next, the examiner will axial load the leg and 
				flex the knee with the lower hand while applying valgus stress 
				to the knee with the upper hand. Once the subluxation is felt 
				the examiner will then extend the leg 30 – 40 degrees to reduce 
				the subluxation. | 
              
                | Positive Test | 
				If 
				an anterolateral subluxation of the tibia occurs along with a 
				reduction of the lateral femoral condyle the test is positive. | 
              
                | Interpretation | 
				 Anterolateral 
				Rotary Instability; ACL Sprain or Tear | 
              
                | Common errors in 
            performing exam | Possible errors in performing this test can include but are not 
				limited to: improper patient positioning, improper examiner 
				positioning, having active participation from the patient, and 
				not allowing the patient to fully relax before and during the 
				examination. | 
              
                | Factors possibly 
            resulting in misinterpretation | Several factors can cause the examiner to read a false negative 
				for this test. If the IT Band is sprained or torn or if 
				excessive swelling is present, the examiner may have a false 
				negative test. Also, if the patient is apprehensive, the 
				protective muscle contractions produced will cause a false 
				negative by not allowing the tibia to slip backwards. |
